TEGU ID #: S11053489 Course Code: GE302 DUE DATE: week -13- 2011 Lecturer: Dr. Tamarisi Yabaki INTRODUCTION Agricultural sector was the most important sector for the economy. It accounts for approximately 30% of the GDP. Agricultural export is a major source of export earnings and it is the main source of employment and livelihood in the rural areas. Agriculture consists of three sub-sectors: subsistence smallholder farming, a commercial sub-sector, and large plantations (Central Bank of Solomon Islands, 2006, Annual Report 2005).On the other hand, the climate of the Solomon Islands is changing and people are now experiencing increased in intensity or severity of extreme events like cyclones, storm surges, floods and droughts. These extreme events are causing substantial damage to agriculture and associated infrastructure with negative impact on food production. In which, There is increasing concern over the consequences of climate change on food production amongst the Pacific Island Countries, Solomon Islands for instance.Already, the changing weather patterns is having some effects soil fertility, pests and diseases, increased heat stress on plants, changes in rainfall and soil moisture, salt water incursion from rising sea-levels and increased damage on agriculture and crops from extreme weather events (Baragamu, G. 2008). Well, in this report it will focus on the effects of climate change on the agriculture expansion in Solomon Islands. However, the research will concentrate looked at the food security and land specifically apart from livestock, fisheries, and forestry as a part of agriculture as well.Besides, the research looks at how effects of climate changes affect land , and result in lessen of food crops such as taro, banana, sweet potatoes, Pineapple, coconut, and so on. Statement of the problem Well, this research project will mainly focus on the climate change and its effect on the agr icultural expansion in SIDS. The problem that this research tried to find it out is that, how do the SIDS will cope with drastic effect of climate change if there is no enough land left for agriculture to expand, for example low-lying lands are covered due to sea-level rise Ontong Java for instances.And also what happened if the crops are affected due to increased of temperature, and humidity where it encourage the plants to die out due to lack of underground water, and also encourage of pests to damage the crops, whilst it lessen the agricultural productions in the country. It leads to downfall of the GDP of the economy, poverty that people will experience. In which it is a problem for Solomon Islands, therefore these research will investigate on the problem, and come with a possible solutions to help them to deal with problem.Significance of the study The significance of this research is that, to find out the most problems, and challenges that face by the Solomon Islands in terms of their agricultural expansion as result of climate change, and how it halt the agriculture development at the community basis or level and to provide some possible solutions to help them to cope with the changing climate. BACKGROUND INFROMATION The country had an estimated population of 508,000, there were nine provinces in the country Malaita is the most populous and Renbel the least populous.The population of Solomon Islands is predominantly Melanesian (about 95%) although there are smaller Polynesian, Micronesian, Chinese and European communities ( Solomon Islands national census statistic, 2007). Moreover, the economy is largely dependent on agriculture, forestry, and fishing. For a high proportion of the population (mainly village-based), the Solomon Islands economy involves the production of subsistence foods and other items for personal consumption.The main item of production for cash at the village level is copra (the dried flesh of coconut), but also significant in some a reas is cocoa, market vegetables and marine products including fish and shells. Export commodities include gold, copra, wood and fish products, and cocoa (Judith A. Bennett 1978) Solomon Islands is a low-lying coastal country that shares similar sustainable development challenges, including small population, remoteness, susceptibility to natural disasters, vulnerability to external shocks, and excessive dependence on international trade and foreign aid.Besides, Solomon Islands have particular problems and concerns in dealing with the effects of climate change, variability and extreme events, and Climate change will be a major impediment to the achievement of sustainable development in Solomon Islands. As all economic and social sectors are likely to be adversely affected, and the cost of adaptation will be disproportionately high, relative to gross domestic product (GDP) (World Bank, 2000). GEOGRAPHICAL LOCATION & INFORMATIONThe Solomon Islands is located between latitudes 5o South and 12o South and longitudes 1520 East and 1630 East in the Pacific Ocean, encompassing a total land area of 28, 785 square kilometres (km-2) and an Exclusive Economic Zone(EEZ) of 1. 34 million km-2. The land area of the Solomon Islands consists of a double chain of six large islands that make up total 997 islands. The double chain of islands is described as a fragmented island arc situated along the boundary between the Ontong Java Plateau-Central Pacific Basin and the Solomon Sea-Woodlark-Torres Basins.A composite basin separates the double chain of islands that make up the main archipelago of the Solomon Islands and is the segment of the Melanesian Island arch complex that separates the Pacific Ocean from the Coral Sea and Solomon Sea (Geography. about Solomon 2005).

To find out whether the halt of agricultural expansion affect the livelihood and nation as a whole. †¢ To find out the challenges or problems that Solomon Islanders or farmers were facing due to climate change. †¢ To determine adaptation and mitigation strategies to cope with the effect of climate change, local and national level. LITERATURE REVIEW According to Kenneth M, and Joel S (1995), they highlighted that agricultural production could decrease in many countries, low-lying land; particularly in deltas could inundated by sea-level rise.Thus, they said that, climate change could cause developing countries to fall farther behind developed countries. In which they provide examples, that agricultural output in many developing may be reduced by climate change compared to what it would be without it, while many developed nations could have increased output, because high dependen ce on climate sensitive systems, and rapid population growth, cause developing countries will be more vulnerable to climate change than developed countries.Besides that, he mention that, countries with large agricultural productions in deltas, such as Egypt, Bangladesh, and China are particularly vulnerable for a 1m sea level rise, in which he people will be at risk because they depend on agriculture for food and monetary purposes. In which Solomon Islands experience the similar problems as stated by the two authors. Well, in addition to that, in the coming decades, many low-lying areas, and plain areas in Solomon Islands will almost certainly suffer from more frequent and intense droughts and floods, which will reduce yields and potentially fuel forest clearance.Moreover, according to Aalbersberg, W. , Nun, P. D. , and Ravuvu, A. D. (1993), stated that climate change has the great effect on agriculture in a sense that increased temperatures will cause heat stress on many plants, an d increased evaporation may lead to increased drought, especially in drier areas during the dry season. Besides that, increased atmospheric carbon dioxide will increase plant growth; faster growth will also lessen time maturity. This could decrease yields and perhaps food values. Weeds will also grow faster, competing with plants for water and soil nutrients, and areas of agriculture would shift.Due to warming upland area could be planted with crops that previously could not be grown there. Sea-level rise will claim coastal land that is currently for agriculture through inundation or salination where it affect the expansion of agriculture whilst it cause the price to accelerate, and the economy of the SIDS will be drop. To more extent, other factors affecting agricultural output may change in a warmer, more humid south-west Pacific. The occurrence of agricultural pests may increase causing lower yields and increased loss during storage.His sum up with one statement which is,† Farmers are likely to be less productive as temperature and humidity increase†. Well, there are ways that the authors highlight to mitigate climate change in terms of agriculture, for example Network internationally, it was global research to find out cultivars that are less sensitive to heat, salt and drought stress, and it required technological developments that help us the pacific to address these problems. However, it is not applicable for the Solomon Islands for instance, because it was very expensive in sense that it required professionals to deal with this kind of experiment and very demand.And also, they didn’t seen the underlying issues of resistance to heat, salt because pacific islands are surrounded by oceans, and even though they find those cultivars but they do not suite the climate conditions in the pacific. The gap of this research is the way forward to achieve the sustainable agriculture where it not cause climate change on the other hand whilst it wil l adapt to the changing environment rather than emphasis on the sophisticated technology with the solutions that cannot applicable for theSIDS, Solomon Islands for instance. Nevertheless, look carefully on the simple methods that agriculture could expand but does not create any green house gases as well. METHODOLOGY The completion of this report was extracting from a wide Variety of sources, which included quantitative and qualitative data. They highlight below under each sub-heading. In addition, the sample size of the population that interviewed are fifteen (15) both students and working staff for supporting ideas for substantiate some ideas gathered from the secondary sources.Quantitative Method Quantitative is a numerical data in which it is gathered and collected from the interviewees and from the secondary sources; for example, collected data from the internet about the total agricultural production that damaged due to effects of climate change. Besides, collected trend of tem perature, and also the amount of rainfall from each meteorological station in Solomon Islands. Hence, the information gathered, and the sources of information will be summaries in the table below. Sources |Types of information |Primary data |Secondary data | |Internet |Total agricultural production that damaged | | | | |Trend of temperature | | | | |Amount of rainfalls | | | | |Rate of change in sea level height | | | However, there were difficulties and challenges faced during the collections of figures, in which the figures collected from the internet and books were general to understand and analysed in order to pick out the relevant figures. Besides, the sample size of the research did not achieve the accurate results because the sample size was very small. QUALITATIVE METHOD Qualitative is normally non-numeric data in which it gathered during data collection. There were many sources of information collected through websites, books, Library, interviews, observation and so forth. Below summaries the types of information gathered and their source.

Besides, the questionnaire are not properly answered due to some students did not understand what climate change is. To more extent, the questionnaires are delay to give it back, thus it delayed to complete my report in time. Despite of the challenges and difficult faced, the information was accessible and available. RESULTS AND FINDINGSSolomon Islands has a climate humid and warm with mean daily maximum temperature of about 300 ? C and a mean daily minimum of about 230 ? C. Rainfall distribution is quite varied with annual average rainfall normally ranges from3000mm to 5000mm. Often drought in the country is associated with the El Nino Southern Oscillation phenomenon (ENSO). From about December to March, a period of west to north-westerly monsoonal winds and abundant rainfall can expected as well as a period where tropical cyclones form and affect the islands. The south-east trade winds (SE trades) blows from around May to October an d trigger higher rainfall particularly on the windward side of the islands (http://www. SolomonIslandsNapa. pdf. com).Figure 1. 0. Shows The annual mean temperature trends for two locations indicate a warming trend since the 1950s. This is consistent with warming trend elsewhere in the Pacific islands region. [pic] [pic] Source: http://www. SolomonIslandsNapa. pdf. com The above two figures obviously indicated the warming trend of two main stations in Solomon Islands since 1950. The best fit maximum temperature approximately starting from 29. 0 C and gradually upward, while the minimum temperature approximately from 22. 0 C and upward. So by telling that because of the mean, it seen the temperature was gradually increasing with respects to the number of years.Therefore, because of the positive changing in temperature it would actually decreased yields of agriculture crops especially taro, potatoes and so forth on the coastal lowlands, and fires can also result from burning of debris in shifting agriculture systems. Moreover, The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (AR4) estimates that sea-level rise over the last century was 1. 7+ 0. 5mm/yr. However, from 1961-2003, the average rate of sea level rise is estimated at 1. 8+ 0. 5mm/yr. Global projection of sea level rise estimated by AR4 ranges from 0. 18m to 0. 59m (IPCC 2007). Thermal expansion accounts for about 75% of the total sea level rise (http://www. SolomonIslandsNapa. pdf. com). Figure 2. 0.Shows the rate of sea level rise in the last 10 years up to 2006 from satellite records. In the southwest Pacific (Melanesia region), the rate of change of sea level height as measured by satellites over the 10 years was at 8-10mm/yr, approximately three times the global average. In more recent measurements of sea level in Solomon Islands from 1994 up to June 2008, indicates the net relative sea level trend at 7. 6mm/yr, which two-time average of the trend up to June 2007. [pic] Source: http://www. SolomonIslandsNapa. pdf. com It clearly, shown above in the global map with respects to scale and colour signify the raising sea level due to the climate change. Moreover focuses ainly on Pacific Ocean especially Solomon islands, and from the map, Solomon Islands is located between latitudes 50 South and 120 South and longitudes 1520 East and 1630 East in the Pacific Ocean. So the color that represent the region is somewhere between the scales reading of 3-9 mm per years. So evidently, Solomon Islands facing the sea level rising which causes salt-water intrusion, storm surge and flooding in low-lying coastal areas of the main islands and the atolls such as Ontong Java are already threatening food crops and livelihoods. Figure 3. 0. While temperature records show a generally warming trend, rainfall records show a downward trend.Rainfall trend for seven meteorological stations in Solomon Islands. [pic] Source: http://www. SolomonIslandsNapa. pdf. com From the grap hs above shows the rainfall trend for the seven meteorological stations in Solomon Islands from each year. Likewise, it showed the amount of rainfall from each provinces in Solomon Islands as well, where in some provinces the amount of rainfall were increasing from1960s , Auki for instance as shown in the map. Therefore, the above station evidently had shown the downward trend of rainfall due to the changing of climate. As compare to the pass years from 1950 the amount of rainfall increase, while in the current years the amount of rainfall going downward.The trend of best-fit line is downward, which indicate the decrease in amount of rainfall, and raise the temperature, where could change the pattern of the environment system. So this may result in high intensity storm events, increased evaporation and more pronounced dry seasons, could have severe impacts on agriculture crop production and intense rainfall during planting seasons could damage seedlings, reduce growth and provide co nditions that promote plant pests and diseases. Moreover, below were the responses from the 15 interviewees on the effect of climate changes and its impact on the agricultural productions in Solomon Islands. Table 1. Show the number of the interviewees’ views on the objectives of the research topic. |Temperature |4 | |The effect of climate change on |Sea level Rise | | |agricultural expansion in Solomon Islands |Rainfall | | | |Cyclone |9 | | |Drought | | | |Flood | | | |Tsunami | | | |Storm surge |2 | |What will happen if the agricultural |National level |8 | |expansion decline?

There a maximum of 15 people, response to the questions and their views a arranged above in the table. More over most of them their views a similar, because of the reality that occur now in the country Solomon islands. Thus, they grouped according to their similarities on the responses. Besides, you can see that many interviewees answer some of the questions and few students answer some of the questions, but it based on what they experience that they see in the Solomon Islands about the effects of climate change, some of their perceptions on the mitigations and adaptations as indicated above.Hence, some of their responses shown above are clearly stated that they really experience the severe effects of climate change in their homes in Solomon Islands, and suffered extensively from the impacts, western Solomon for instance where they heated by the Tsunami in 2007, in which they lived in poverty for a long period before they recovered. By saying this because, they lost their farms both subsistence and commercial farming, and the entire valuable belongings, house, and stuffs inside are damaged due to the drastic event. Figure 4. Shows the summary of the table into graph in percentage [pic] The pie chart showed the percentage of the responses, and by looking at the graph, it showed that, 75 percentages of the res ponses were strongly agreed that effect of climate change had a great impacts on food security, 20 % of the responses were fair in weighing the effects of climate change and other factors.And 5 % they did not sure of the effects of climate change on food security. EFFECTS OF CLIMATE CHANGE ON THE AGRICULTURAL PRODUCTION AND EXPANSION IN SOLOMON ISLANDS Table 2 a. Table shows the effect of climate change on agricultural productions that collected from the interviewees’ views and from other research findings in Solomon Islands. |Direct effect of climate change |Impacts | |Cyclone |Increased intensity/frequency of cyclones could have dramatic effects on agriculture and food | | |production that often lasts for many years. | |Also, after the immediate effects, pests and diseases could come in later damaging the newly grow | | |crops. | | |For examples, Cyclone Namu in 1986 had dramatic effects on commercial agriculture (palm oil and rice)| | |in Solomon Islands, particularl y rice production has not recovered, and there is now a heavy reliance| | |on imported rice. | | |Rural people experienced downfall of food security due to the event. |Drought |Drought in different localised parts of the country, as influenced by ElNino and La Nina in 1987 | | |people experienced a long period of droughts , had a great impacts on food production | | |cause crops to die due to less underground water for the crop to absorb | | |Agricultural systems were seriously affected by drought conditions, and increased air temperature. | | |Coconut trees and pandanus trees, which are most resilient to dry conditions, wither away during | | |prolonged droughts.Other crops breadfruit, banana and Giant swamp taro are in a worse state | | | | | | | |Floods |Cyclone Namu in 1986, flooding the crops both subsistence and commercial crops, decreased in food | | |security for the people, and export commodities as well. | | |Damaged the entire farm, e. g. the crops are underg round. | | |Cause the root crops to rotten, e. g. cassava, sweet potatoes, taro, vegetables and so on. | | |Flooding low-lying coastal areas of the main islands and the atolls such as Ontong Java are already | | |threatening food crops and livelihoods. | |It lessen the production , and it affect the local markets in urban areas because less production | | |they sold in the market, and it cause the price of the crops to accelerated, where even the goods in | | |the shop are cheap as compared to the cultivated crops. | | |Storm surge and flooding in low-lying coastal areas of the main islands and the atolls such as Ontong| |Storm surge |Java, Tikopia, Anuta are already threatening food crops and livelihoods. |Tsunami | | | |Washed away crops, such as coconut, sweet potatoes, and vegetables and so on in the western part of | | |Solomon Islands in 2007. | Table 1b. Shows the indirect effects of climate change |Indirect Impact of Climate Change |Impacts | |Temperature |Increased temperatures – A correlation has been found between rising temperatures and decreased | | |yields of taro on the coastal lowlands of Makira (Legu 2006).

The | | |alternate scenario of increased rainfall could have equally severe impacts with waterlogged soils | | |decreasing agricultural production, while increased humidity an d rainfall could provide ideal | | |conditions for the proliferation of a number of plant pathogens. E. g.Malaita province in Solomon | | |Islands | | |These conditions could lead to declining agricultural production and this would adversely affect | | |both the country’s economy and food security | | |Plants flowering earlier than usual while others are fruiting much later than normal during the past| | |3-4 years Pineable for instance.

Well there were two tables above which is figure 1a and b, and they were categorize in two different sub headings which is direct effects and indirect effects of climate change as shown clearly.Seeing that they affected the food security in b oth ways, which is the Solomon Islanders are experience food insecurity and less production for export especially, cocoa, copra, and oil palm for instance. Take for example climate change affect our food security directly as shown above, where by the crops were damaged instantly at the spot when the event strike, and lessen the foods for the household and as well as the productions at the national level in the Solomon Islands. While indirectly effects happened in another way around, where as a result of the sea level rise, it cause salt intrusion and coastal erosion, which lead to less land along the coast for crops and cash crops, cocoa for instance to grow. Table 2: shows the crops that are vulnerable to climate change as stated by the interviewees. crops |Effects | |Taro |Easily destroyed by cyclone | |Sweet Potatoes |Damaged by flooding | |Cassava |Damaged by High intensity of rainfall and cyclone | |Cocoa |Damaged by flooding | |Coconut |Destroyed by sea level rise | |Pinea ble |High intensity of rainfalls where it delay the flowering , and as well as the harvesting | |Cabbage |Spoiled the leaves to rotten | |Giant swamp Taro |Cause to turn yellow colour due to salt intrusion, less underground water | |Yam |High rainfalls, and cyclone cause the crop to rotten, and damaged | |Pana |High rainfalls and cyclone | |Palm Oil |Flooding due to intensity rainfalls | This table showed the type of crops that are vulnerable to climate change, for example Taro, Cassava in which they can easily destroyed by the cyclones and high intensity of rainfall. During cyclones, there always be a strong wind and associate with heavy rain falls, whereby it totally damaged the taro leaves into pieces, and the breeze from the sea can cause the taro leaves to turn yellow due to the high intensity of salt, Thus, it cause the Taro corm to rotten.Besides, the strong wind also damaged the Cassava stalk. If the cassava is premature in which it affect the root crops to small in size for the stage of maturity or if not it cannot yield or have no root crops anymore, because it disturbed the growth. Moreover, cocoa, oil palm and coconut are the major cash crops in Solomon Islands; and, they highly vulnerable to sea level rise and flooding result from eroding of coastal land or coastal erosion where it dug the coconuts out, and flooding could wiped the cocoa and oil palm out due to the great force of the current. Along the same line, it digs the riverbanks and causes the cocoa along the rivers to wash down along the river.Figure 4: shows the percentages of agricultural productions that affected due to the effects of climate change from 2004 to 2007. [pic] Source: Central Bank of Solomon Islands, 2006, Annual Report 2005 The figure above obviously had shown the outcomes of agriculture production that was affects by the climate change as from 2004 to 2007 both subsistence and commercial. Well the output affects product was increases accordingly, like in 2004, the affect ed products percentage was 21%, 24% for 2005, followed by 25% for 2006 and 30% for 2007 and as it continues the percentage will increases accordingly. This is because of the changes in temperature and rainfall and the occurrence of tropical cyclones in Solomon Islands.Now day families and communities experience inadequate supply of food from their garden, which leads to the limited products supply due to the following experiences: †¢ Yield from staple fruits trees is not sufficient to meet the food needs of the population and this problem is exacerbated by natural cycle and weather pattern changes. †¢ Yield from roots crops is not sufficient to meet the food needs of the population because of declining soil fertility and poor choice of root crop varieties. †¢ Yield from supplementary sources of food (bush, and gardens) have declined because of climate change and sea level rise. †¢ Less production export in which it decrease the GDP of the economyIn addition, coas tal garden areas (mainly taro patches) were flooded by seawater for long period, and caused the swamp taro tubers to turn yellow and bitter rendering them not suitable for Consumption. Hence, Seawater flooding also affected the quantity and quality of potable water supply that could be exacerbated by drought conditions. Thus for Ontong Java sea-level change and its concomitant consequences are already being experienced. DISCUSSION Well agriculture sector was the backbone of the pacific islands countries, particularly Solomon Islands because it accounts and contributes in to the economic sector with higher percentage of the GDP.Not only that but it was also accommodated the daily and sustainability of earning for the rural people (Legu, M. 2006). Therefore, it is a concern for every people and well as government to take action, adaption and mitigation strategies on this issue of growing climate changes on the food security and agriculture production. Refer to figure 1. 0. It depict o ut the increasing minimum and maximum temperature of two main islands, Malaita and Guadalcanal of Solomon islands since the 1950s. Besides, the best fit maximum temperature approximately from 29. 0 ? C and gradually upward, while the minimum temperature approximately from 22. 0 ? C and upward.From that, you can see that best fit is continuously increasing from 1950s to 2007, likewise from 2007 to 2011 in which the temperature might 30. 0 ? C from the estimation from the figure. Besides, the figure 1. 0 was true because it back up the evidence from the interviewees, where they said that they experienced droughts, and hot session not like before. Where, some of the grasslands in Guadalcanal province were in flame, due to the friction between the grasses itself and the hot weather. These lead to the massive destruction on the crops due to the burning, and diminish the growth of the agricultural crops because of inadequate nutrients and ground water to the support the growth of the crop s.Increased temperatures resulted in a correlation has been found between rising temperatures and decreased yields of taro on the coastal lowlands of Makira (Legu 2006). Fires can also result from burning of debris in shifting agriculture systems. For example, in 1997 and 1998 ENSO, people experienced a long period of drought , result in hunger due to poor quality of crops because they are affected by disease because they breed in dry session, sweet potatoes for instance, and so on, where only few crops have left, in which it reduced in food supply for the household consumption (Legu 2006). Besides, swamp water for the Giant swamp Taros were dried up, and they are dead due to no water for them to keep alive and as well rice farms.Whilst, it reduced in food security and even the production, rice for instance for both daily consumption and export were affected. Along the same line, in 2002, they experienced the long sunshine period due to effects of climate change, and it has the grea t effect on food security in a sense that increased temperatures will cause heat stress on many plants, and increased evaporation may lead to increased drought, especially in drier areas during the dry season, (Personal Interview of Dr. Morgan). Hence, it affected the food production to be less in the central market in Honiara, where it causes the price of the crops too expensive for the urban dwellers especially for the low-income earners. Moreover, according to figure 2. 0.It shows the rate of sea level rise in the last 10 years up to 2006 from satellite records. In the southwest Pacific (Melanesia region), and Solomon Islands is one of them. Likewise, the record indicates that from 1994 to 2008 the relative trend of sea level rise is 7. 6 mm per year for Solomon Islands (http://www. SolomonIslandsNapa. pdf. com). Well, estimated from 2008 to 2011 where the global trend of the seal level rise is 1. 1 mm per year, in which absolutely it rise to 11 mm according to the record from th e estimation. In addition, sea level rise spoil the swamp Taros and cause intrusion to the leaves to turn yellow because it resist to salination, and even the corm of the swamp Taros (Kakake) are perished.Hence it affect the food security to reduce and some household experienced hunger during flooding, and diseases, because this food can substituted instead of high land taro, and sweet potatoes and so on for their survival. besides, it signifies that coastal land are eroding, where it reduced the size of the land to plant coconut and cocoa Plantations where they used to reside along the coast in which they found land areas to plant. To more extent, from the responses of the interviewees, it shows that sea level rise and Cyclones and storm surges was a major problem especially the low-lying coast in Solomon Islands especially, Ontong Java, Tikopia, Anuta, western Solomon, and northern Solomon. For example, a storm in early 2006 coinciding with high tides caused extensive floods on th e two permanently inhabited islands, Luaniua and Pelau.And Ontong Java considered highly vulnerable to cyclones due to the high exposure and sensitivity to impacts from flooding, dependence on few crops (mainly coconuts and taro) and wind-sensitive house constructions. In addition, from the interviewees, especially the students from western part of Solomon Islands, they said that, they experienced the great massive of destruction on the agricultural productions and as well taking life of human. For example, in 2007, the Tsunami heats the coastal area in western Solomon and split the villages into half, and washed away the crops along the coast, and they experienced great hunger ever in their lives that they did not experienced in life before. (Personal Interview with students). Below is the picture of the Tsunami in 2007. [pic][pic] Source: by Calwin, 2007As you can see from the picture above, the Tsunami split the Coconut Plantation, and all the coconut trees along the coast were w ashed away, and with their homes. The impacts result in coastal erosion, and eroded of the large area of land that planted by coconut and cocoa trees, and the sea come through the inner part of the land and washed ? part of the plantation away. Likewise, it results in shortage of supplies to the main centre for exporting, because less coconut and cocoa ripe fruits collected for dryer. Hence, it reduced the revenue coming into the country for increased the economy in terms of the GDP, this is because coconut and cocoa are primary products and main source of export from Solomon Islands.Well, it affected the household income basis because less income received from the selling of the dryer coconut flesh and dry and wet cocoa beans, result in hindrance for their livelihood in terms of living standard. Likewise, they suffered from the drastic event until today. Furthermore, agricultural productivity in PICs is heavily dependent on the seasonal rainfall. About 70% of the gross cropped area in the Pacific Islands is geographically located to benefit from rains in the summer season (November – April). Well, most of the rural population in Solomon Islands lived and cultivated crops in areas where annual rainfall was in the range 1800–3500 mm.In mountainous locations where clouds formed early in the day and reduced sunlight, human settlement and agriculture was generally absent. Localities where the annual rainfall was more than 4000 mm tend to be wet and have too much cloud covered for good agricultural production. The variation of the normal rainfall can have many impacts to the agriculture products like shift of rainfall patterns affect planting time, growing stages, harvest periods, post harvesting storage and drastically reduced the total yield (World Bank, 2000). Cocoa production is widely distributed throughout Solomon Islands, grown in all provinces except Rennel/Bellona, which makes cocoa the second most important cash crop after coconut.The high r ainfall in production areas led to severe outbreaks of the Black-pod disease having devastating effects on production ( personal interviews with student). Agriculture and crop productions were under stress from these climatic factors but it remains difficult to predict the likely outcomes with certainty because of limited empirical data for the Solomon Islands. These can affected the local food consumption and the total exports of products per year, which also contributed to the decline in country GDP. Hence, by observation the most destructive impacts of excessive rainfall on agriculture infrastructure and crops are flooding and water logging.For example, Cyclone Namu in 1986 had dramatic effects on commercial agriculture (palm oil and rice), and in Solomon Islands, particularly rice production has not recovered, and there is now a heavy reliance on Imported rice (personal interviewed with Dr. Morgan, 2011). Another example, flooding in 2009-caused damage to gardens and the oil pal m and other outdoor crops, these in fact lead to lose in output oil palm and other farmers loses. And affected the livelihood of the people both rural and urban dwellers, and even at the national level GDP for instance reduced because less merchandise to export (Lizzie Tegu, 2009). Below show some pictures in 2009 flooding in Solomon Islands and affected the outskirts of the Town Honiara, even further away from the City in Guadalcanal province. [pic][pic]Source: shot by Lizzie Tegu, 2009 These pictures have taken during the flood in 2009 but just outskirt of the cities, and only few but not all pictures. Moreover, from the analysis of the interviewees’ views or responses from the tables, it come with the summary that, absolutely the food security was rapidly reduced due to the effects of climate change that discussed above. Well, it shown that, Solomon Islanders facing a great challenges and problems but they do not realized the real effects on the food security, in which the y experienced less food for household consumption, and some urban dwellers experienced the price of the crops were increasing so fast from year to year.Imagine that even the crops were very expensive than the proceed food in the shops in Solomon Islands, where the price should decrease because there was no Taxes, labour cost on the crops, but it shown that the productions is reduced but they do not know the exact causes. In addition, from some findings shows that there are great percentage lose from the agricultural production especially food security both in rural areas and outskirt of the city of Honiara. Where figure 4, give the actual data, each year the percentage of the crops were decreased due to cyclones, flooding, seal level rise, drought, and so on as indicate from the table above. As you can see below was the picture taken during the Cyclone that affected Tikopia, and Lordhowe (http://www. SolomonIslandsNapa. pdf. com). [pic] Source: http://www. SolomonIslandsNapa. pdf. o m). From the responses, highlighted that, flooding was a major problem in Solomon Islands, Guadalcanal province where Honiara city is located, it have a great massive destruction on the Oil palm plantation, where it washed away the new seedlings and even dig out the big Oil palm trees and through the river to the seas. Where it results in low export of Oil palm to the global market and it really affected the GDP of the economy to fall and experience devalued in currency. Besides, the sweet potatoes, melons, vegetables were damaged and covered with ground, and it happen every year in Solomon Islands during heavy rains associate with cyclones.Where it affected the food security to reduce, and daily income of the people halt and it affected the purchasing power of the rural people for other necessities from the shops. The interviewees’ responses gave me clear picture that some of their places where they plant their crops covered with seas, Makira province in Solomon Islands for instance. Besides, the coconut and cocoa plantation really affected by the sea level rise because it would erode the coconut and cocoa trees into the sea and covered with seas today especially my home village, and it seen that the half bottom coconut was standing in the beach, but before there was a land mass that occupied with coconut plantations.Thus, it affect the owner of the plantations because their plantation size already reduce, and it can lessen the mature coconut fruits during their maturity stage to fall, where they can make 10 bags of coconut drier only to sell it for the Liver Company Limited for exporting. While before he can make 30 bags out of the plantation during one harvest. Likewise, it really shown the great changes on his output, and even the income he received also reduced as he expected for his family survival. Therefore, climate change was really a challenge to hinder the living of people in terms of the income they received from their productions, and to th e extent, the production for exporting also reduced and it cause the GDP of the economy to fall. The adverse impacts on agriculture and food security are a major concern for many communities and/or villages.Evidence from changes in temperature and rainfall and the occurrence of tropical cyclones in Solomon Islands will have long-term effects on food production systems. MITIGATION AND ADAPTATION STRATEGIES Below are the suggestions from the interviewees and from other findings in Solomon Islands. a) National Food Security programme, food security issue is common to all service providers in the agriculture sector. b) Provincial Food Banks – To mitigate and prepare against the effects of climate change such as cyclones, tsunamis, floods, and pest outbreaks, provincial food banks must be established at strategic sites. c) Crop diversification – The introduction of various crops to boost food production and economic development in the country must continue. This activity ca n be one by all players in agriculture development. d) Tolerant crop species – salt, drought, high rainfall, etc. – Crop varieties that are tolerant to extreme effects of climate change must be identified and rapidly propagated and distributed to hot spots. e) Rapid Response to disasters – exotic pests and diseases outbreaks, floods – An agriculture rapid response center must be established to prepare for any disasters such as pest and disease outbreaks. f) Weather forecasting- Predicting outbreaks of pest and diseases on crops -Developing capacity and capability to predict weather patterns such as weather simulations and pest and disease outbreaks would reduce crop loses. ) Weather stations establishment at agriculture production areas – The establishment of weather stations at agriculture field stations would ensure that data on rainfall, sunlight, and temperature are kept. This information is critical for crop production. h) National Urban Fruit Tree Planting – Planting fruit trees in urban centers such as Honiara, Auki, Gizo, Kirakira, Buala, Lata, Taro, Tulagi, and Tingoa. This will serve two purposes; as a source of fresh fruits and as beautification of the towns. It is vital for everyone in Solomon Islands to practices this adaptation and mitigation to improve their food security and even safe side during those drastic events happening in our country.Besides, Government must work hard by giving out people to give awareness or workshops on the type of system in order to implement in the communities in the provinces in Solomon Islands. CONCLUSION From the findings, it shown clearly that Climate change is a threat to Solomon Islands as it affected the livelihood of people both directly and indirectly in rural and urban areas in terms of hunger, decreased in household income, and affected their purchasing power because agriculture is the source of living in Solomon Islands. And, to the extent it affected the nationa l level in the country as well due to decreased in GDP result from less merchandize export.Hence, Government and individuals should act on by looking for possible adaptation and mitigation strategies or adapt to the highlighted ones above to help each other, in order to minimize the impacts on the food security, and as well as the welfare of the nation.

Organic food †Agriculture Essay

What is Organic Food? Organic farming is a relatively new concept to us, though we are practicing it for thousands of years without noticing. Organic farming is nothing but cultivating foods and other agricultural products using methods that do not involve modern synthetic inputs such as synthetic pesticides and chemical fertilizers, do not contain genetically modified organisms, and are not processed using irradiation. Organic food is produced with: †¢No synthetic pesticides, herbicides or fumigants †¢No fertilizers made with synthetic ingredients or sewage sludge †¢No genetically modified organisms (GMOs). †¢No irradiation †¢No hormones, antibiotics, artificial ingredients or trans fats In simple words organic farming is way and means to cultivate naturally, in other word primitively in a sense. The primary goal of organic agriculture is to optimize the health and productivity of interdependent communities of soil life, plants, animals and people. A Brief History of Organic Food: Until the early part of the 20th Century pretty much all the food grown across the world was organic. It wasn’t called organic food – it was just food. Nobody had thought of putting chemicals into soil and sprays to enhance crop growth and yield. And genetic engineering took place over generations as farmers selectively bred to improve their stock or their seeds. Organic food farming continued in small, mostly family-run, farms or kitchen gardens where people grew food for their own requirements. The produce was sold in farmer’s markets. Large scale organic farming was begun by farmers and scientists, as a mark of protest to the agricultural industrialization. With the rise of the petro-chemical industries in the early 1900s, agricultural research became focused very much on the chemicals that are needed for plant and animal growth. That these chemicals come from finite resources, most often as by-products of oil refining, was rarely thought of. That they could cause other problems was seldom recognized until the problems became too big to ignore. In the 1930s there was a reaction against the use of chemical additives in people’s food. It was led, in part, by Rudolf Steiner who also designed an educational system based on his holistic and sustainable outlook. These early organic farmers and foodies laid the foundations for today’s interest in sustainable lifestyles. Now, organic food is widely available and has become very popular, with soaring sales. Principles of Organic Agriculture: These Principles are the roots from which organic agriculture grows and develops. They express the contribution that organic agriculture can make to the world, and a vision to improve all agriculture in a global context. The Principles of Organic Agriculture serve to inspire the organic movement in its full diversity and guide our development of positions, programs and standards. Principle of Health. Organic Agriculture should sustain and enhance the health of soil, plant, animal, human and planet as one and indivisible. This principle points out that the health of individuals and communities cannot be separated from the health of ecosystems – healthy soils produce healthy crops that foster the health of animals and people. Health is the wholeness and integrity of living systems. It is not simply the absence of illness, but the maintenance of physical, mental, social and ecological well-being. Immunity, resilience and regeneration are key characteristics of health. The role of organic agriculture, whether in farming, processing, distribution, or consumption, is to sustain and enhance the health of ecosystems and organisms from the smallest in the soil to human beings. In particular, organic agriculture is intended to produce high quality, nutritious food that contributes to preventive health care and well-being. In view of this it should avoid the use of fertilizers, pesticides, animal drugs and food additives that may have adverse health effects. Principle of Ecology Organic Agriculture should be based on living ecological systems and cycles, work with them, emulate them and help sustain them. This principle roots organic agriculture within living ecological systems. It states that production is to be based on ecological processes, and recycling. Nourishment and well-being are achieved through the ecology of the specific production environment. For example, in the case of crops this is the living soil; for animals it is the farm ecosystem; for fish and marine organisms, the aquatic environment. Organic farming, pastoral and wild harvest systems should fit the cycles and ecological balances in nature. These cycles are universal but their operation is site-specific. Organic management must be adapted to local conditions, ecology, culture and scale. Inputs should be reduced by reuse, recycling and efficient management of materials and energy in order to maintain and improve environmental quality and conserve resources. Organic agriculture should attain ecological balance through the design of farming systems, establishment of habitats and maintenance of genetic and agricultural diversity. Those who produce, process, trade, or consume organic products should protect and benefit the common environment including landscapes, climate, habitats, biodiversity, air and water. Principle of Fairness Organic Agriculture should build on relationships that ensure fairness with regard to the common environment and life opportunities Fairness is characterized by equity, respect, justice and stewardship of the shared world, both among people and in their relations to other living beings. This principle emphasizes that those involved in organic agriculture should conduct human relationships in a manner that ensures fairness at all levels and to all parties – farmers, workers, processors, distributors, traders and consumers. Organic agriculture should provide everyone involved with a good quality of life, and contribute to food sovereignty and reduction of poverty. It aims to produce a sufficient supply of good quality food and other products. This principle insists that animals should be provided with the conditions and opportunities of life that accord with their physiology, natural behavior and well-being. Natural and environmental resources that are used for production and consumption should be managed in a way that is socially and ecologically just and should be held in trust for future generations. Fairness requires systems of production, distribution and trade that are open and equitable and account for real environmental and social costs. Principle of Care Organic Agriculture should be managed in a precautionary and responsible manner to protect the health and well-being of current and future generations and the environment. Organic agriculture is a living and dynamic system that responds to internal and external demands and conditions. Practitioners of organic agriculture can enhance efficiency and increase productivity, but this should not be at the risk of jeopardizing health and well-being. Consequently, new technologies need to be assessed and existing methods reviewed. Given the incomplete understanding of ecosystems and agriculture, care must be taken. This principle states that precaution and responsibility are the key concerns in management, development and technology choices in organic agriculture. Science is necessary to ensure that organic agriculture is healthy, safe and ecologically sound. However, scientific knowledge alone is not sufficient. Practical experience, accumulated wisdom and traditional and indigenous knowledge offer valid solutions, tested by time. Organic agriculture should prevent significant risks by adopting appropriate technologies and rejecting unpredictable ones, such as genetic engineering. Decisions should reflect the values and needs of all who might be affected, through transparent and participatory processes. How can we be sure that our Food is Organic? The early followers of organics were often dismissed as anti-scientific cranks. Nowadays, organic production is one of the fastest growing sectors of agriculture, and there are millions of dollars being spent to research more sustainable farming methods. But, unfortunately, organics still account for a minority of the foods grown. Most nations have a government regulated system that certifies that those people who claim to be selling organic produce are actually doing so. It will vary from country to country, but most systems will be affiliated with the international umbrella organization IFOAM. We can check with IFOAM to make sure that the organic accreditation is actually recognized. Types of Organic Food: Organic products grown in healthier soil contain higher amounts of nutrients, and many taste better than their conventional counterparts. Hence, the popularity of such produce is picking up volumes in recent years. There is no better choice for one’s consumption than organic produce. The major types of organic foods are: Organic Vegetables and Fruits Organic vegetables and fruits are the most common type of organic food that is available in the market. They come in a wide variety and they are usually in good quality. Any certified organic plant product must come from fields that have remained free of chemical application of fertilizers and pesticides for at least three years, and must follow regulations set by Agri-Food and Veterinary Authority of Singapore. Organic Meat Organic meat is perfect for meat lovers as in is healthy and not contain any chemicals in the meat as the animals are fed with natural food that does not contain chemicals. Organic provisions require animals to be raised without receiving antibiotics, hormones, or growth stimulants. Humane treatment and access to the out-of-doors are stipulated, and the animals must be fed 100% certified organic feed and must graze in certified organic pastures. Organic Dairy Products Organic dairy products are extremely popular in recent years as they are safe and healthy to consume. Milk from all dairy animals, including cows, goats, and sheep, may be certified organic. Certified organic products cover nearly the full dairy spectrum, including milk, cheese, yogurt, butter, cottage cheese, sour cream, ice cream, and more. Organic Fish Organic fish are fishes that are rare in fish farms such as salmon, trout, cod, halibut and sea bass. Fishes that are caught in the open see cannot be labeled as organic due to the fact that it is uncertain of what the fishes eat. Advantages of Organic Foods: The debate about the advantages of organic foods is over. According to a new $25-million study into organic food – the largest of its kind to date – organic food is more nutritious than ordinary produce and it may help to lengthen peoples lives and prevent disease. More Nutrients The European Union funded study found that organic fruit and vegetables have up to 50% more antioxidants, which scientists believe can cut the risk of cancer and heart disease. They have also more vitamins and minerals such as iron and zinc. According to other recent studies, organic foods are better for fighting cancer. And people eating organic food have improved immune system, better sleeping habits and are less likely to be overweight than when eating â€Å"conventional† foods. (Can you imagine the benefits of eating both raw and organic food? ) Better Taste The taste of organic fruits and vegetables is often superior to any conventional produce. That’s why many top restaurants use organic produce in their menu. Today, most fruits and veggies are manipulated to look and stay good. The strawberries from your ordinary supermarket may look great on your cake but they have virtually no taste. However, the taste of fresh organic fruits is irresistible! Safer for Babies and Children The advantages of organic foods might be highest for babies. The average baby is born with 200 toxins and carcinogens in its body. By the time kids reach their 2nd year, most have pasted the lethal limit for the toxins. By feeding your child organic food, it will have about 1/6th the amount of carcinogens in its blood. Thus you will decrease the chances of illnesses significantly. Therefore, especially for infants and children a raw organic food diet is incredibly important. Irradiation? Do we ever wonder why organic vegetables and fruits seem to spoil so much faster than produce from normal supermarkets? The reason is that many foods are irradiated. Irradiation kills bacteria and extends food life. But, it also alters the molecular structure and life force of the food. Some irradiation methods use radioactive substances, others high energy electrons or X-rays. I don’t know about you, but I prefer my food pure and not irradiated. So one of the advantages of raw organic foods is that it still has life force. Raw organic seeds grow – cooked and irradiated seeds don’t GMO Secrets Organic food stores don’t sell genetically modified (GM) food. It’s suspected that GM food causes allergies and decreases your immune system. Government is being secret – at least vague – about the health consequences of GMO food. I’ve read enough to not want to take a chance. Do you? Shocking Animals Organic meat, fish and poultry is healthier for you. Organic farmed animals are raised without dangerous chemicals, growth hormones or antibiotics. Pesticides used in ordinary farming don’t just affect the animal who eats it first. They accumulate in their tissues (mostly fat). Animals on top of the food chain get the highest concentration of these chemicals. Conventional animals full of toxins and dirt. A cow, chicken or pig will retain most of the pesticides it has ever eaten (directly or indirectly through other animals). Factory farm animals are fed great quantities of (polluted) fish, food doused in pesticides and fed many unnatural compounds never eaten by wild animals. Inorganic animal food (meat, fish, dairy and eggs) is a main source of pollution to the environment. According to research animal food contribute to as much as 95% of the toxic chemical residues in the American diet. Meat, fish and poultry have 10 times the amount of the dangerous chemicals DDT, DDE and TDE as conventional produce. In addition intensive farming is incredibly cruel to farm animals. One of the most outrageous advantages of organic foods is that organic farms treat their animals much more humane. They place a great emphasis on animal welfare. Just for this reasons, switching to an organic living makes sense. And even consider becoming vegan. Save the Environment Organic food facts are especially striking if you consider the environment. Conventional farming methods erode soil and use dangerous pesticides that may take centuries before they’re gone. Think of the DDT, thought to be harmless but appeared to be extremely bad for your health. Even though this pesticide has been forbidden for many years now, it’s still found in virtually all waters, human beings and animals in the world†¦ In addition, over time, artificial pest controls become less and less effective, so that even more chemicals must be used or other methods found. One of the huge advantages of organic food is that buying it has a huge positive impact on the environment, the animals and people who live on it. Organic vs. Non-organic: A new study looking at the potential health benefits of organic versus non-organic food found that fruit flies fed an organic diet recorded better health outcomes than flies fed a nonorganic diet. The study from the lab of Southern Methodist University biologist Johannes H. Bauer, Southern Methodist University, Dallas, found that fruit flies raised on diets of organic foods performed better on several tests for general health. Flies on organic food performed better on some health tests â€Å"The data demonstrated that flies raised on organic food extracts by-and-large performed better on the majority of health tests,† reported the researchers. It remains unclear why organic diets delivered better health, the researchers said. The Bauer lab results come at a time when the health effects of organic food are widely debated. Prior studies by other researchers have found conflicting results when reviewing the scientific literature for data. While several studies have shown elevated nutrient content and lower pesticide contamination levels in organic food, a recent publication reporting a large-scale analysis of all available studies concluded no clear trend was apparent. Organic farming only uses naturally occurring chemicals or traditional remedies to control pests and diseases. According to public perception, organic food is the healthy option. Sales of organic produce have rocketed over the past few years with the organics industry sending out messages of safer, healthier food created by farming practices which are better for the environment. But is it really as good as we think? Critics argue that organic farming leads to the risk of contamination with potentially dangerous bacteria and mould toxins, and increased levels of ‘natural pesticide’ found in organic produce could even be as dangerous as synthetic chemicals. So who do we believe? Are organic fruit and vegetables as harmless as they appear? And why do they cost so much? In this piece, common views about this subject are discussed. Is organic food the healthier option? Is it as safe as the public think? Many in the public perceive organic food as the healthy option. However, organo-sceptics argue that organic food may not be as safe as we think. †¢The public’s viewpoint is based on the fact that no synthetic pesticides or fertilizers are used in organic agriculture leading to the assumption that no pesticide residues are present on the products. Without the use of pesticides, organic crops develop a natural defense mechanism in the form of chemicals all called phenols. The organic supporters claim that these chemicals are antioxidants and that organic fruit and vegetables are better at protecting the body from cancers and heart disease. Organic-sceptics argue that these natural pesticides may be a potential health risk and insist that there is no evidence to show health gains from organic food. The lack of evidence, however, may be due to the difficulty in conducting such a study. †¢The use of manure as a fertilizer in organic farming leads to fears of contamination of produce with bacteria such as E.coli which could lead to food poisoning. However, it has been shown that by composting the manure for a precise time at an exact temperature, the amount of bacteria present is greatly reduced. As long as these conditions are adhered to, the risk of food poisoning is kept to a minimum. †¢Another significant concern regarding organic farming is the contamination of produce with toxic substances produced by moulds called mycotoxins. There is a greater chance of crops being vulnerable to moulds if they are damaged by insects or weather. The organic lobby argues that although less effective fungicides are used in their farming methods, organic produce is less prone to fungal attack as crops are not fed with chemicals known as nitrates which may make plant cells in conventional crops more vulnerable to fungal growth. Are the levels of pesticides used in conventional farming enough to damage health? The quantities of pesticides used in agriculture are declining as the industry is developing more efficient methods of delivery and pesticides which have the ability to target specific pests more accurately. Pesticides have played an important role in improving crop yields but are often hazardous materials. Care must be taken when using such materials to ensure that they are applied as advised to minimize risks associated with misuse. Before a pesticide can be used commercially its safety must first be proved. The law requires that only pesticides approved by Government regulators shall be sold, supplied, used, stored or advertised. This ensures that the levels and toxicity of all pesticides used in agriculture are at a safe level. Is organic farming a viable option in the developing world? It is argued that without pesticides and genetically modified crops, farming is not economically viable in the developing world. Non-organic farming allows you to farm land that would otherwise not be farmable. Yields are high and costs are low. However, there is a worry that intensive farming in these countries will destroy the fertility of the land and in the long run organic farming will secure the future for sustainable farming. Why is the price of organic produce so high? Crop rotations, higher animal welfare standards and restricted use of chemicals, leading to lower yields, all mean that organic food costs more to produce. Subsidies from the government are paid mainly to farmers with non-organic farms allowing them to keep their prices low. The pro-organic lobby argues that when buying non-organic food you are in fact paying threefold; once at the counter, second via taxation and third to remedy the environmental pollution. As the sector develops and technologies are improved, the cost of organic food should decrease as yields increase and production costs decrease. Organic Food market: From economic point of view, organic market is growing very fast worldwide. A simple statistics can tell a lot. According to Data monitor’s â€Å"Organic Food: Global Industry Guide†, the global organic food market grew nearly 10% in 2009 to reach a value of $60 billion and market is forecasted to have a value of $96. 5 billion in 2014. Organic agriculture offers enormous trade opportunities for farmers in the developing and least developed countries. This organic market expansion makes it possible for farmers to reap the benefits of a trade with relatively high price premiums. Food producer have also found fast growing markets for natural and organic products. One example is Earthbound Farm, a company that grows and sells organic product. It started in 1984 as a 2. 5-acre raspberry farm in California’s Carmel Valley. Founders Drew and Mera Goodman wanted to do the right thing by farming the land organically and producing food they’d feel good about serving to their family, friends, and neighbors. Today Earthbound Farm has become the world largest producer of organic vegetables, with 40000 acres under plug, annual sells of $480 million, and products available in 75% of America supermarkets. Organic farming, on the other hand, promotes the health of both consumers and the environment contrast to modern farming. The main problem with modern agriculture, however, is that the synthetic chemicals never disappear. When we eat a mango grown using synthetic pesticides, traces of the pesticides remain in the mango, and the chemicals end up in our fat cells. Similarly, cotton grown using synthetic chemicals retains traces of the chemicals after it is woven into a fabric. Chemicals, used for cultivation are then absorbed into the plant, air, soil, water, and eventually, our bodies. Started after mid 1950’s reaction against modern toxic farming methods, organic farming excludes the use of synthetic pesticides, herbicides, fertilizers, and genetic engineering. Organic farmers respect their land: they feed and build the soil with natural fertilizers; they protect crops against insects using natural insect predators, barriers, or traps; and they control weed growth with crop rotation, hand weeding, cover crops, and mulches. In the past decade, the organic agriculture market has grown exponentially because more consumers are learning that organic farming is better for them and their environment. How can we market Organic Products? The marketing model used in conventional agriculture is not easily applied to organic systems. Currently, local elevators that accept organic grains are not common, though they do exist in some areas. Farmers that transition to organic production must also transition their marketing strategies. Whether growing organic grains, herbs, fruits and vegetables, or raising organically certified livestock, marketing becomes an additional consideration. Producers who have always sold to local elevators will find that quality time will be needed to do a good job with marketing organic products. Organic Foods Strategic Marketing and Communications The â€Å"Go Green† trend is quickly gaining momentum. Law makers are actively working to pass legislation that promotes the development of green energy sources, manufacturers are researching technologies that can be used to produce new biodegradable products, and USDA certified organic foods are increasingly finding their way into every home. More than other green initiatives, the demand for organic foods has soared in recent years. With the implementation of new federal requirements for labeling of natural and organic foods, and the growing research that suggests links between foods produced using antibiotics, hormones, pesticides, irradiation or bioengineering and illnesses such as cancer, Parkinson’s disease and Alzheimer’s disease, consumers are gaining confidence in the quality and benefits of organic foods and increasingly rejecting their conventionally produced counterparts. As young people grow up consuming organic foods and learn to accept them as healthier and more eco-friendly, the organic foods industry will continue to gain market share. Many organic farmers link in to existing networks of organic wholesalers, exporters and processors. Others use the opportunity provided by their change to organic, to take on a completely different approach such as direct marketing to consumers. This fact sheet discusses some of the options for marketing of organic produce and poses some questions to be considered as we develop our marketing strategy. A small but rapidly growing market The market for organic food and fiber has been growing around the world for some years now. It is however still very small, making up only about one per cent of the world total market value. One of the risks associated with supplying product into a small market, is that of oversupply of certain products, leading to depressed prices. To help avoid this situation, some market research is vital early in the process of considering organic conversion and certification, as highlighted below. Some organic farmers manage the risk of oversupply in organic markets by selling into conventional markets when necessary. This means sacrificing any organic price premium, but can help to stabilize prices in the organic market – a benefit in the longer term. Organic price premiums. Many organic products receive a price premium, justified by higher costs of production under organic management. Such premiums are not guaranteed and can be influenced by the supply and demand situation and product quality. Whether or not your produce is likely to attract a premium price, and whether or not a premium is necessary for economic viability, should be considered during your market research and development of a marketing strategy. Consider marketing options early One of the first steps in the process towards organic certification is to identify marketing options. We should ideally have our markets organized before you begin certification, especially if you think you will need to receive a price premium to cover extra costs arising from organic management. The change to organic marketing may be easy if you already sell direct to end-consumers or retailers who might welcome the access to organic produce, or to wholesalers and exporters who have links to organic markets. If your wholesalers/exporters currently have no links with the organic industry, are they interested in pursuing organic certification to diversify their business? If not, some research may be required to identify suitable alternative marketing options. Develop a marketing strategy When you are planning your change to organic farming and are looking at marketing options, take the time to consider what your marketing objectives are and how you might achieve them. Pulling this and other relevant information together into a marketing strategy will help us to focus your efforts in the most productive areas. Some key points to consider are: †¢Be closely involved in selling your produce or leave it to a ‘professional’ marketer? †¢Maintain a diversity of markets to spread the risk in case the usual supply chain fails for you? †¢Have direct contact with end consumers? †¢Use customer feedback to guide farm production (e. g. crop varieties and seasonal availability)? †¢Increase financial security by improving returns? †¢ Consider different marketing options Following are options that organic farmers commonly use to market their produce, along with some of their pros and cons from a farmer’s perspective. Often a range of different options will be used to balance the risk, the workload and the prices obtained. 1. Direct to consumers 2. Direct to retailers 3. Direct to Wholesaler 4. Use mass media Look for opportunities to tell a story that gets media attention as this exposes potential new customers to our organic business and products. One area of opportunity is to piggy-back onto relevant local, state, national and global events. For example, contact local media with an interesting story about: †¢National Organic Week (e. g. highlight local organic production and produce availability) †¢Earth Day and World Environment Day (e. g. how organic farming reduces environmental impacts). †¢Organic Day (e. g.promote citizen buying organic produce within the country as an example) †¢National Tree Day (e. g. plant a treed spray buffer) †¢World wetlands day (e. g. how your farm protects its wetland) Organic Food in Bangladesh: Organic certification is the parallel tool needs to develop getting the market opportunity worldwide. Those who intend to label and market their foods as organic will usually seek certification – almost certainly if they grow for the export market. However, many farmers practice organic techniques without seeking or receiving the premium price given to organic food in some markets. This includes many traditional farming systems found in developing countries. Agriculture that meets organic production standards, but that is not subject to organic inspection, certification and labeling, is referred to as ‘organic by default’. While economic and institutional conditions differ, both certified organic agriculture and organic agriculture ‘by default’ rely on the same technology and principles. Although the results might be similar, organic agriculture ‘by default’ may not always represent a deliberate choice between alternative productions. Organic certification focuses on this part. We may have a huge farm producing by default organic product. Organic certification will just convert it certified and added a huge value. Organic certification scheme varies from country to country regulators. The two sources of general principles and requirements governing organic production and trade are: Firstly, the ‘Basic Principles’ of the International Federation of Organic Agriculture Movements (IFOAM), a private sector international body, with some 750 member organizations in over 100 countries. IFOAM defines and regularly reviews, in consultation with its members, the Basic Standards that shape the organic term. According to IFOAM basic standards ‘organic agriculture is a whole system approach based upon a set of processes resulting in a sustainable ecosystem, safe food, good nutrition, animal welfare and social justice. Organic production therefore is more than a system of production that includes or excludes certain inputs. ’ But in order to access the major organic markets in Europe and United States, one has to comply with specific regulations that are instituted in these countries. These are Regulation 834/07 in the case of Europe and the National Organic Programmed (NOP) in the case of United States. Certification Bodies operating following above stated standards, need to take accreditation from an accreditation body under ISO/IEC Guide 65 for demonstration their competence. Bangladesh Accreditation Board (BAB) is ready to play its role in this regards. We expect our entrepreneurs to come forward with initiative for launching organic farming and organic certification body. BAB will provide all necessary support as national Accreditation Body.

Iran during this time also suffered defeats by the Russians which culminated with the Shah of the Qajar dynasty, Naser Al-Din Shah ruling the middle of Iran while the Russians ruled the north and the British ruled the south. The Qajar dynasty was in dire straits as a result and it did not help that the Shah was spending his country into a more precarious position than he was already in. By the late 19th century the Shah due to his opulent life style began to issue concessions to each power ruling its upper and lower regions for a fee. A concession is an â€Å"amicable† agreement to give a certain right such as the ability to improve infrastructure in order that the concession holder have a monopoly over this enterprise in its given area. An example would be both Russia and Britain wanting to have concessions of the railroads in their given sectors, this did not happen.

Gothic Literature The Southern Gothic Fiction - 1476 Words

Authors use morbidly dark and eccentric characters combined with southern charm and the ever-present gender divide to tell stories that represent a writing style known as southern gothic literature. â€Å"Southern Gothic is a subgenre of Gothic fiction unique to American literature that takes place exclusively in the American South. Elements of a Gothic treatment of the South were apparent in the 19th century, ante- and post-bellum, in the grotesques of Henry Clay Lewis and the de-idealized visions of Mark Twain.[3] The genre came together, however, only in the 20th century, when Dark Romanticism, Southern humour, and the new Naturalism merged into a new and powerful form of social critique.† (Wikipedia) Almost all stories told in the southern gothic genre have blemished characters that act in strange and weird manners, often told with dark, deadly humor. Set in the south, story lines are always ominous and disastrous focusing on poverty, estrangement, illegal activity and/or brutality. These writings are fraught with gender bias and typically centered on common southern themes such as the downfall of the southern upper class and the futility of the southern plantation.

Essay about Druids and Druidism A Study of Their Real...

When interpreting history it is almost akin to separating the wheat from the chaff in farming. Close attention has to be paid to every historical detail that is given. In many cases when studying a historical description the reader can find a particular bias that the author has written with. The writings of Julius Caesar and Pliny are not exempt from being written with a bias when they describe the druids. Both authors are considered to be valid sources on historical events which make the assertions and observations that they noted more reliable than other authors. Upon a cursory observation of the text it seems that Caesar tended to find fewer faults in the druids customs compared to Pliny. This paper will argue and prove that although†¦show more content†¦Caesar makes no comment on this difference but instead keeps relaying the facts. Another part that ties into the religious description that Caesar gives is the druid’s rights to enact punishment. For instance, â₠¬Å"if a private person or the public does not yield to their decision they are prohibited from sacrifices† these people are regarded â€Å"as godless and wicked and they are cut off from all.† (Caesar, 21) This shows that the druids were very powerful not only when it came to religious matters but also matters that dealt with the public. They had the power to ostracize entire clans from the rest of the Celts for any type of religious misconduct by a particular clan. The position of druid was coveted by the Celt people, so much so that many men were sent by â€Å"parents and relatives† to try to become one.(Caesar, 21) This was not an easy task though. â€Å"They are said to commit to memory a great number of verses†¦ and remain some twenty years in training.† (Caesar, 21) Part of the reason for the extensive training that went on is that the druids refused to commit â€Å"things to writing.† (Caesar, 21) One can only imagine the great mental ca pacity that each one of these individuals had to have. The huge amounts of information that had to be memorized did two things for the druids. One it deterred anyone who did not really have the

Domar Growth Model free essay sample

According to Thrall (2000), tariff levels in highly developed nations have skimmed down dramatically, and now average approximately 4 percent. Tariff levels in developing nations of the world have also been reduced, although they still remain relatively high, averaging 20 percent in the low-and middle-income countries. Non-tariff barriers to trade, such as quotas, licenses and technical specifications, are also being gradually dismantled, but rather more slowly than tariffs. Regional Trade Agreements (Arts) have also become very fashionable in the form of Free Trade Areas and Customs Unions. The WTFO lists 76 that have been established or modified since 1948. The major ones are the European Union (ELI); the North American Free Trade Area (NONFAT); Mercury covering Argentina, Brazil, Paraguay, Uruguay and Chile; APES, covering countries in the Asia and Pacific region; SEAN covering South-East Asian countries, and SACS, covering countries in southern Africa. The liberalizing of trade has led to a massive expansion in the growth of world trade relative to world output. While world output (or GAP) has expanded fivefold, the volume of world trade has grown 16 times at an average compound rate of Just over 7 percent per annum. In some individual countries, notably in South-East Asia, the growth tot exports has exceeded ten percent per annum. Exports have tended to grow fastest in countries with more liberal trade regimes, and these countries have experienced the fastest growth of GAP (Thrall, 2000). Foreign trade can be defined as commercial transactions (in goods and/or services) across international frontiers or boundaries. Foreign trade plays a vital role in estimating economic and social attributes of countries around the world. The workings of an economy in terms of growth rate and per-capita income have been based on the domestic production and consumption activities and in conjunction with foreign transactions of goods and services. Further, the role of foreign trade in economic development is considerable and the relationship between openness and economic growth has long been a subject of much interest and controversy in international trade literature. The classical and neo-classical economists attached so much importance to foreign trade in a nations development that they regarded it as an engine of growth. Over the past several decades, the economies of the world have become greatly connected through international trade and globalization. Foreign trade has been identified as the oldest and most important part of a countrys external economic relationships. It plays a vital and central role in the development of a modern global economy. Its impact on the growth and development of countries has increased considerably over the years and has significantly contributed to the advancement of the world economy. The impact of foreign trade on a countrys economy is not only limited to the quantitative gains, but also structural change in the economy and facilitating of international capital inflows. Trade enhances the efficient production of goods and services through allocation of resources to countries that have comparative advantage in their production. Foreign trade has been identified as an instrument and driver of economic growth (Franken and Roomer, 1999). It has been stated theoretically and proven empirically that economic openness contributes to the level of the economy (Errors and Denizen (201 1); Shaky (201 1); Chuddar et al (2010)). This is because in a competitive environment, prices get lower and the products become diversified through which consumer surplus emerges. Gains from specialization and efficiency are also further advantages of economic openness. Hence, it is quite reasonable that economies generally desire to be economically open. Of the various objectives of foreign trade, the promotion of economic growth and stability holds more weight. Various researchers have, in their various research works, delved into studying the numerous advantages and gains obtainable from trade between economies. As a result, there has therefore been an increasing interest in the study of foreign trade and its benefits particularly to developing countries. However, (recent) empirical investigations have not been able to show how healthy or otherwise, vastly (or scarcely) opened boarders are to economic growth. Actual gains from trade rather than gains accrued to vastly or scarcely open boarders are most often, the major points of discourse in most research. To this end, this research work concerns itself with examining how porous the Nigerian economy should be towards foreign trade. How exactly wide and receptive should the economy accommodate foreign trade in the quest for sustained long run economic growth? This study focuses extensively on the trade pattern of Nigeria over the years with more attention on the various trade policies or programs that and been adopted over the years. Relevant trade theories ranging trot classical theories to contemporary trade theories shall be highlighted. The Real Gross Domestic Product (Real GAP) shall be used as the indicator for the economic growth of Nigeria. The study time frame shall be restricted to fall between 1980 and 2011. The relevant questions in this research are: What has been the pattern of international trade in Nigeria? Has trade openness in Nigeria stimulated economic growth? To what extent should the economy be open to foreign trade in the quest for sustainable long run growth and development? Therefore, the main objectives of this paper are to: (1) examine the pattern of international trade in Nigeria. 2) determine if indeed, trade openness stimulates economic growth in Nigeria and, (3) determine the extent to which the economy should be open to foreign trade in the quest for sustainable long run growth and development. Congregation analysis is adopted for this study to test for the long run relationship between trade openness and economic growth in Nigeria. Individual variable relationship between the various trade openness indicators and economic growth variable (Real GAP) will be established and actual functional relationships will be determined using the LOS estimation method. The Augmented Dickey-Fuller unit root test for stationary will also be conducted for the variables of interest. Secondary data would be used in this study. The relevant data to be used would be sourced from the Central Bank of Insignias statistical reports, annual reports and statement of accounts for the years under review. The remaining part of the paper is structured as follows: in Section 2 we present a brief review of related literature alongside relevant trade and growth theories while Section 3 provides some stylized facts about the subject matter. Section 4 is on the Research Methodology and Empirical Result. In Section 5, we conclude the research work. 2. Review of Related Literature and Theories. Openness refers to the degree of dependence of an economy on international trade and financial flows. Trade openness on the other hand measures the international competitiveness of a country in the global marked. Thus, we may talk of trade openness and financial openness. Trade openness is often measured by the ratio of import to GAP or alternatively, the ratio of trade to GAP. It is now generally accepted that increase openness with respect to both trade and capital flows will be beneficial to a country. Increased openness facilitates greater integration into global markets. Integration and globalization are beneficial to developing countries although there are also some potential risks (aloha and Rakish, 2002). Trade openness is interpreted to include import and export taxes, as well as explicit non tariff distortions of trade or in varying degrees of broadness to cover such matters as exchange-rate policies, domestic taxes and subsides, competition and other regulatory policies, education policies, the nature of the legal system, the form of government, and the general nature of institution and culture (Baldwin, 2002). One of the policy measures of the Structural Adjustment Programmer (SAP) adopted by Nigeria in 1986 is Trade Openness. This meaner the dismantling of trade and exchange control domestically. Trade liberalizing has been found to perform the role of engine of growth, especially via high real productivity export (Baden, 1993). He argued that with export, a nation can take advantage tot division tot labor and procure desired goods and services from abroad, at considerable savings in terms of inputs of productive resources, thereby helping to increase the efficiency of the export industry. Export Roth sets up a circle of growth, so that once a country is on the growth path, it maintains this momentum, of competitive position in world trade and performs continually better relative to other countries. The doctrine that trade enhances welfare and growth has a long and distinguished ancestry dating back to Adam Smith (1723-90). In his famous book, and inquiry into nature and causes of the wealth of nations (1776), Smith stressed the importance of trade as a vent for surplus production and as a meaner of widening the market thereby improving the division of labor and the level of productivity. He asserts that between whatever places foreign trade is carried on, all of them derive two distinct benefits from it. It carries the surplus part of the produce of their land and labor for which there is no demand among them, and brings back in return something else for which there is a demand. It gives value to their superfluities, by exchanging them for something else, which may satisfy part of their wants and increase their satisfaction. By meaner of it, the narrowness of the labor market does not hinder the division of labor in any particular branch of art or manufacture from being carried to the highest perfection. By opening a more extensive market for whatever part of the produce of their labor may exceed the home consumption, it encourages them to improve its productive powers and to augment its annual produce to the utmost, and thereby to increase the real revenue of wealth and society (Thrall, 2000). We may summarize the absolute advantage trade theory of Adam Smith, thus, countries should specialize in and export those commodities in which they had an absolute advantage and should import those commodities in which the trading partner had an absolute advantage. That is to say, each country should export those commodities it produced more efficiently because the absolute labor required per unit was less than that of the prospective trading partners. (Applecart and Field, 1998) In the 19th century, the Smithsonian trade theory generated a lot of arguments. This made David Richard (1772-1823) to develop the theory of comparative advantage and showed rigorously in his principles of political economy and taxation (1817) that on the assumptions of perfect competition and the full employment of resources, countries can reap welfare gains by specializing in the production of those goods with the lowest opportunity veer domestic demand, provided that the international rate of exchange between commodities lies between the domestic opportunity cost ratios. These are essentially static gains that arise from the reallocation of resources from one sector to another as increased specialization, based on comparative advantage, takes place. These are the trade creation gains that arise within customs to trade are removed between members, but the gains are once-for-all. Once the tariff barriers have been removed and no further reallocation takes place, the static gains are exhausted. The static ins from trade stem from the basic fact that countries are differently endowed with resources and because of this the opportunity cost of producing products varies from country to country. The law of comparative advantage states that countries will benefit if they specialize in the production of those goods for which the opportunity cost is low and exchange those goods for other goods, the opportunity cost of which is higher. That is to say, the static gains trot trade are measured by the resource gains to be obtained by exporting to obtain imports more cheaply in terms of resources given up, compared to producing the goods oneself. In other words, the static gains from trade are measured by the excess cost of import substitution, by what is saved for not producing the imported good domestically. The resource gains can then be used in a variety of ways including increased domestic consumption of both goods (Thrall, 2000). Baldwin (2003) has demonstrated persuasively that countries with few trade restrictions achieve more rapid economic growth than countries with more restrictive policies. As poverty will be reduced more quickly through faster growth, poor countries could use the trade liberalizing as a policy LOL. Trade liberalizing reduces relative price distortions and allows those activities with a comparative advantage to expand and consequently foster economic growth. Poor countries tend to engage in labor-intensive activities due to an overabundance of available labor. Thus the removal of trade barriers in these countries promotes intensive economic activity and provides employment and income to many impoverished people. On the other hand, the pursuit of trade-restrictive policies by labor endowed poor countries distorts relative prices in favor of capital-intensive activities. The removal of trade barriers could lead to a decline in the value of assets of protected industries and therefore to the loss of Jobs in those industries. This implies that trade liberalizing has distributional effects as industries adjust to liberalized trade policies. Economist Ann Harridans 1991 paper makes a synthesis of previous empirical studies between openness and the rate of GAP growth, comparing the results from cross- section and panel estimations while controlling for country effects. Harrison concluded that on the whole, correlations across openness measures seem to be positively associated with GAP growth the more open the economy, the higher the growth rate, or the more protected the local economy, the slower the growth in income. On the other hand, trade restrictions or barriers are associated with reduced growth rates and social welfare, and countries with higher degrees of protectionism, on average, tend to grow at a much slower pace than countries with fewer trade restrictions. This is because tariffs reflect additional direct costs that producers have to absorb, which could reduce output and growth. Franken and Aroma (1999) and Irwin ND Torero (2002) in their separate and independent studies also suggested that countries that are more open to trade tends to experience higher growth rates and per-capital income than closed economy. Klaxon and Rodriguez Clare (1997) used general equilibrium model to establish that the greater number of intermediate input combination results in productivity gain and higher output, despite using the same capital labor input which exhibit the economics increasing international trade return to scale. Nigeria is basically an open economy with international transactions constituting a significant proportion of her aggregate output. To a large extent, Insignias economic development depends on the prospects of her export trade with other nations. Trade provides both foreign exchange earnings and market stimulus for accelerated economic growth. Openness to trade may generate significant gains that enhance economic transformation. This meaner that, there will be diffusion of knowledge and innovation amongst other open economies tot the world . Trade openness has been hailed for its beneficial effects on productivity, the adoption and use of better technology and investment promotion which are channels for stimulating economic growth. Over the years, Nigeria has identified deeper trade integration as a meaner to foster economic growth and to alleviate poverty. 2. Theoretical Review 2. 1. 1 TRADE THEORIES: Trade as Engine of Growth. The origins of trade can be traced to the absolute and comparative advantage as well as Heckler Olin theories Momma, 2001). The theory of absolute advantage was formulated by Adam Smith in his famous book title Inquiry into the nature and the wealth of Nations 1776. The theory emanated due to the dem ise of mercantilism. Smith argued that with free trade each nation could specialize in the production of hose commodities in which it could produce more efficiently than other nations and import those commodities it could not produce efficiently. According to him, the international specialization of factors in production would result in increase in the world output. Thus this specialization makes goods available to all nations. 2. 1. 2 Comparative Advantage Theory This theory was propounded David Richard. The theory assumed the existence of two countries, two commodities and one factors of production. To him a country export the commodity whose comparative advantage lower and import commodity whose imperative cost is higher. The theory also assumed that the level of technology is fixed for both nations and that trade is balanced and rolls out the flow of money between nations. However, the theory is based on the labor theory of values which states that the price of the values of a commodity is equal to the labor time going into the production process. Labor is used in a fixed proportion in the production of all commodities. But the assumptions underlying is quite unrealistic because labor can be subdivided into skilled, semiskilled and unskilled labor and there are other factors of production. Despite the limitations, comparative cost advantage cannot be discarded because its application is relevant in explaining the concept of opportunity cost in the modern theory of trade. . 1. 3 Heckler-Olin Trade Theory The theory focuses on the differences in relative factor endowments and factor prices between nations on the assumption of equal technology and tastes. The Model was based on two main propositions; namely; a country will specialize in the production and export of commodity whose production requires intensive use of abundant resources. Secondly, countrie s differ in factor endowment. Some countries are capital intensive while some are labor intensive. He identified the different in pre-trade product prices between nations as the immediate basis of trade, the prices depends on production possibility curve (supply side) as well as the taste and preference (demand side). But the production possibility curve depends on factor endowment and technology. To him, a nation should produce and export a product for which abundant resources is used be it capital or labor. The model suggests t developing countries are labor abundant and therefore they should concentrate in he production of primary product such as agricultural product and they should import capital intensive product I. . Manufactured goods from the developed countries. The model also assumes two countries, two commodities and two factors and that two factors inputs labor and capital are homogeneous. The production function is assumed to exhibit constant return to scale. However, the theory is not free from criticism and this because factors inputs are not identical in quality an d cannot be measured in homogeneous units. Also factor endowment differs in quality and variety. Relative factor prices reflect differences in relative factor endowment- supply therefore outweigh demand in the determination of factor prices. Despite this criticism, trade increases the total world output. All countries gain from trade and it also enables countries to secure capital and consumption of goods from the rest of the world. 2. 2 THEORIES OF ECONOMIC GROWTH Economic growth is best defined as a long term expansion of productive potential of the economy. Trend growth is the smooth path of long run national output I. E. It requires a long run series of macroeconomic data which could be twenty years or ore. The trend of growth could be expanded by raising capital investment spending as a share of national income as well as the size of capital inputs and labor supply, labor force and the technological advancement. There are different schools of thought that have discussed the causes of growth and development and they are discussed below. 2. 2. 1 Neo-classical Growth Theory. This was first propounded by Robert Solos over 40 years ago. The model believes that a sustained increase in capital investments increased the growth rate only temporarily, because the ratio of capital to labor goes up. The marginal product of additional units is assumed to decline and thus an economy eventually moves back to a long term growth-path with the real GAP growing at the same rate as the growth of the workforce plus factor to reflect improving productivity. Neo-classical economists who subscribe to the Solos model believes that to raise an economy long term trend rate of growth requires an increase in labor supply and also a higher level of productivity of labor and capital. Differences in the rate of technological change between countries are said to explain much of the variation in growth rates. The neo-classical model treats productivity improvements as an exogenous variable which meaner that productivity improvements are assumed to be independent of the amount of capital investment. 2. 2. 2 Endogenous Growth Theory. To them, they believe that improvements in productivity can be attributed directly to a faster pace of innovation and external investment in human capital. They stress the need for government and private sector institutions to encourage innovation and provide incentives tort individual and business to be inventive . There is also central ole of the accumulation of knowledge as a determinant of growth I. E. Knowledge industries such as telecommunication, electronics, software or biotechnology are becoming increasingly important in developed countries. The proponent of endogenous growth theory believes that there are positive externalities to be exploited from the development of a high value added knowledge economy which is able to developed and maintain a competitive advantage in fact growth within the global economy. They are of the opinion that the rate of technological progress should not be taken as a constant in a growth model- government policies can rearmament raise a country growth rate if they lead to move intense competition in markets and help to stimulate product and process innovation. That they are increasing returns to scale from new capital investment and also private sector investment is a key source of technical progress and that investment in human capital is an essential ingredient of long term growth. . 2. 3 Harrow Dammar Growth Model Harrow-Dammar opined that economic growth is achieved when more investment leads to more growth. They theory is based on linear production function with output given by capital stock (K) tines a constant. Investment according to the theory generates income and also augments the productive capacity of the economy by increasing the capital stock. In as much as there is net investment, real income and output continue to expend. And, for full employment equilibrium level of income and output to be maintained, both real income and output should expand at the same rate with the productive capacity of the capital stock. The theory maintained that for the economy to maintain a full employment, in the long run, net investment must increase continuously as well as growth in the real income at a rate sufficient enough to maintain full capacity use of a growing stock of capital. This implies that a net addition to the capital stock in the form of new investment will go a long way to increase the flow of national income. From the theory, the national savings ratio is assumed to be a fixed proportions of national output and that total investment is determined by the level of total savings I. E. S = SYS which must be equal to net investment, l. The net investment which is I = AK = KAY because K has a direct relationship to total national income. And, therefore SYS = KAY which simply meaner AY/ Y is growth rate of GAP that is determined by the net national savings ratio, s and the national capital output, K in the absence of government, the growth rate of national income will be positively related to the saving ratio I. . The more an economy is able to save and invest out of a given GAP, the greater the growth of GAP and which will be inversely related to capital output ratio. The basis of the theory is that for an economy to grow, it should be able to save and invest a certain proportion of their GAP. The basis for foreign trade rests on the fact that nations of the world do differ in heir resource end owment, preferences, technology, scale of production and capacity for growth and development. Countries engage in trade with one another because of these major differences and foreign trade has opened up avenues for nations to exchange and consume goods and services which they do not produce. Differences in natural endowment present a case where countries can only consume what they nave the capacity to produce, but trade enables them to consume what other countries produce. Therefore countries engage in trade in order to enjoy variety of goods and services and improve their peoples standard of living. . Some Stylized Facts. Nigeria is Sub-Sahara Africans second largest economy, with nominal 2006 GAP of $Bonn (at APP) behind South Africans $Bonn. It has also been one of Africans fastest growing economies, outpacing South Africa, Kenya, Ghana and most of its neighbors with a CARR of 7% over the past 10 years. However, its growth has been more erratic due to the high reliance on natural resources (see further UNDO, Human Development Report 2007). Despite the fast pace of growth and the strong resource endowment, Nigeria has so far not increased its GAP per capita beyond that of its mailer and resource-poor neighbors. Its GAP per capita is below that of Cameroon, Ivory Coast, Kenya, and it is only 12% that of South Africa. Poverty and the rural nature of the Nigerian economy put pressure on financial services institution to innovate and to reach out to poor customers. Insignias economy is heavily reliant on the oil and gas sector. It makes up more than 40% of the GAP (Natural Resources and Industry), and accounts for virtually 100% of exports and 80% of budgetary revenues for the government. Nigeria is the worlds 12th largest producer of oil, mainly applying the US. Next to natural resources the most important sector is agriculture, accounting for approximately 35% of GAP. A large portion of this is subsistence farming with declining productivity. This composition of GAP is quite unlike that of its neighbors, due to the importance of natural resources in the country. The natural resources sector is one of the drivers of sophistication in the financial services industry. While rising oil and gas prices have had a strong positive effect on GAP, exports and government revenues over time, it has however, not been Insignias only river of growth. For instance, in 2007 political unrest in the Delta region affected oil production, but strong growth in the non-oil sector meant that overall GAP still grew by 5. 8%. The non-oil sector has grown at a 7% CARR over the past 10 years. This growth is expected to remain robust, due to good performances in certain sectors of the economy, particularly in communications, wholesale and retail trade, and construction; the financial sector will play a key part in facilitating further growth in the economy. Hence, as a result of the large volume of oil export in Nigeria, it is clear hat foreign trade is essential in ensuring foreign earnings which should enrich the nations foreign exchange/national reserves with a view to exploring such surpluses into growth related activities for the country. 4. Research Methodology and Empirical Result This section basically concerns itself with the methodology of the research as well as presenting the result of econometric estimation and gives explanation of various findings. The importance of this section lies in its quantitative and empirical content within which the purpose of this study would be Justified. Also of importance in this heaper is the overall findings and validation of hypothesis tested. This section is therefore divided into two namely: model specification and general discussion of results obtained from the various unit root test, LOS estimation as well as the congregation analysis. 4. Model Specification Following the production attention theory which snow now the level tot a count productivity depends on foreign direct investments (FED), trade openness (OPEN), exchange rates (EXERT) and government expenditure (JEEP), we specify our model showing how the interplay of these chosen variables actually affect the economic growth of Nigeria. The mathematical model will be based on the methodology adopted by Jude and Pop-Silages (2008) for the countries Romania and Karakas; Mohammed and Giovanni (2005) for 42 developing countries. However for this study, we make some slight adjustments to the adopted methodology to suit the scope within which this study covers. The model used for this study has been so chosen because of its relevance to the Nigerian environment and availability of data. The dependent variable chosen for this study as proxy for economic growth is the real gross domestic product, written as RIGID. The explanatory variables are: Exchange ate, Foreign Direct Investment, Government Expenditure and Trade Openness. Mathematically, the functional relationship between variables of interest is as written below: RIGID = f(VPN, EXERT, FED, JEEP) ? Writing the above equation explicitly in an econometric sense, we have: RIGID = With a view to lingering equation (it), we apply the Logarithmic function thus: Where , and are regression parameters and is the standard error term, which is a random variable and has well defined probabilistic properties. Also, OPEN = Degree of openness, determined by the sum of total imports and exports, divided by total output I. E. EXERT = Real exchange rate in Nigeria FED = Foreign Direct Investments from abroad to the country JEEP = Government Expenditure in the country. The signs on the variables are based on the priori expectations from theory, which is the direction of the relationship between the respective independent variables and the explained or dependent variable. The Real GAP variable is included to capture the growth and activity of the economy. How well an economy is performing, how rich an economy is, as well as how the condition of general well-being in an economy is re all captured in the RIGID variable. The degree of openness, OPEN, measured as the ratio of the sum of total export and total imports to the GAP. According to Allege and Sousaphone (2013), African economies can be regarded as largely open in view of OPEN at an average of about 104. 85% over the period of study and 82. 26 per cent in 2007 only. Open economies are preferred by market seeking and efficiency seeking investors since there are fewer trade re

A brief description the features of telecommunications networks, including key networking technologies. Cover the Open Systems Interconnection (OSI) model, including each logical layer A telecommunications network includes the following features: 1. Terminals for accessing the network 2. Computers that process information and are interconnected by the network 3. Telecommunications links that form a channel through which information is transmitted from a sending device to a receiving device. 4. Telecommunications equipment that facilitates the transmission of information. . Telecommunications software that controls message transmission over the network. (1) Key networking technologies includes the traditional telephone system, mobile cellular communication, wireless local-area networks, videoconferencing systems, a corporate Website, intranets, extranets, and an array of local and wide-area networks, including the Internet (2) The ISO/OSI model was designed to formulate a standard for allowing different types and brands of computers to communicate with one another. It’s a conceptual model for the communication process that has seven discrete layers each with a specific responsibility or function: Physical-defines the electrical, mechanical, procedural, and functional specifications for activating and maintaining the physical link (such as the cable) between end systems; Data Link-provides reliable transit of data across the physical link and is responsible for the physical addressing, data error notification, ordered delivery of frames and flow control; Network-provides connectivity and path selection between two end systems This layer uses routing protocols to select optimal paths to a series of interconnected subnetworks and is responsible for assigning addresses to messages; Transport-responsible for guaranteed delivery of data It uses data units called datagrams, it is also responsible for fault detection, error recovery, and flow control, this layer manages virtual circuits by setting them up, maintaining them and shutting them down; Session –responsible for establishing, maintaining and terminating the communication session between applications; Presentations-responsible for formatting data so that it’s ready for presentation to an application this layer is also responsible for character format translation, such as from ASCII to Unicode, and for syntax selection; Application-this layer is responsible for giving application access to the network; (3) Discuss whether telephone networks and computer networks will remain distinct in the future. We will write a custom essay sample on Networking Essentials or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Two months ago, ATamp;T petitioned the Federal Communications Commission to plan for the retirement of traditional phone networks and transition to what ATamp;T sees as inevitability: the all-IP telco. ATamp;T had been discussing the transition internally, spurred on by the FCCs own suggestion that the Public Switched Telephone Network might be ripe for death somewhere around 2018. This telephone network weve grown up with is now an obsolete platform, or at least a rapidly obsolescing platform. It will not be sustainable for the indefinite future. Nobodys making this network technology anymore. Its become more and more difficult to find spare parts for it. And its becoming more and more difficult to find trained technicians and engineers to work on it. As you can see, the largest company of the telecom industry is opening the dialogue of ending the traditional telephone network. Many may not agree with thus but I think we should be ready if it happens. More and more people are opting out of landlines and opting in wireless/voice of IP. (4) Description of the various network media and how they are changing Telecommunications links may be implemented with various communication media, with a corresponding variety of characteristics. The main feature of a medium is its potential transmission speed, also known as channel capacity, which for data transmission purposes is expressed in bits per second (bps). An alternative measure of transmission channel capacity is bandwidth the range of signal frequencies that can be transmitted over the channel. Six potential media are employed to implement telecommunication links: 1. Twisted pair 2. Coaxial cable 3. Fiber Optics cable 4. Terrestrial Microwave 5. Satellite Transmission 6. Radio Transmission How they are changing Transmission speeds keep on rising, particularly in the fiber optics area. We are now moving toward a global infrastructure of gigabit-speed fiber optic links relying on digital transmission. In this multimedia environment, data, text, voice, images, and video will travel at speeds of billions of bits per second. (5) A brief explanation of the differences among LANS, WANS, CANS, and MANS; There are several types of computer network designs- you are more than likely familiar with the LAN, or local area network. But the fun doesn’t stop there- we have MANs, SANs, CANs, and more â€Å"ANs† than you can shake a stick at. But don’t worry- if you can remember what the first letter in each acronym means, you’re set! And that much more prepared for your networking exams! ) What is a LAN? If you aren’t already familiar with a LAN, it is defined as a local area network. From the term local, you’d probably guess that LAN network designs don’t span a large region (and you’d be correct). The basic LAN is just a sim ple network of computers, although LANs can often span multiple buildings. In the example below, you can see a network divided by a router, which is being used to connect the network to the internet. In general there are three things to remember about a LAN: Three Things to Remember about LANs * 1. They operate within a limited geographical area * 2. They allow a large amount of users to access media with high-bandwidth capability * 3. They prove full-time connectivity with local services A LAN is a fairly easy concept to grasp- perhaps the simplest of all networks. In fact, computer networking started out with a simple LAN connection. Since the birth of the LAN, we have been graced with even more advanced technologies- such as the WAN. The Difference between a LAN and a WAN WANs are networks that interconnect LANs. You can think of it as a company who has offices in three separate states. If the company wishes to have each office on the same network, they would need to somehow connect the LANs together. Whereas a WAN enables you to send an instant message to someone around the world, a LAN would be limited to a much smaller geographical location. You are actually more familiar with WANs than you think- you’re using one right now! The internet is biggest WAN on Earth. Looking at it from a global perspective, you can see a WAN as a collective of networks run by many people- whereas a LAN is often ran by a specific organization (and thus usually only has one administrator). In general, there are three things to remember about WANs: Three Things to Remember about WANs * 1. They operate using serial interfaces * 2. They generally provide lower bandwidth compared to LANs * 3. They provide full-time remote resources that are connected to local services Generally speaking, we could stop there. But we can further classify network designs even further with MANs and CANs. What are MANs and CANs? A MAN is short for metropolitan area network. As the name implies, it covers a metropolitan area- such as a city or the suburbs of a city. You can think f them as between what a LAN and WAN would be. They span a much larger geographical area than LANs, but do not often surpass the limits of a metropolitan area. MANs are generally good for businesses and organizations that have multiple locations around a city. A bank may also take advantage of a MAN. So, far so good, right? Well now we’ll introduce the CAN- the campus area network. You’ve probably guessed it- this type of network design spans a university or campus. It acts a lot like a MAN would in some cases, although it obviously has a much more specific purpose. 6) Describe three (3) ways in which businesses use Internet services and protocols. (For example, what is VoIP and how is it used? Businesses are increasingly using the internet services as a means to conduct business. Here a just a few: The internet VoIP phone has taken over the market by force. If you do not know what a internet VoIP phone is then you can research information on the Vonage phone company. Basically, it is a phone that is connected through the internet instead of the phone socket in the wall. That are some good things and bad things about an internet VoIP phone but the good seems to outweigh bad.
