which factors physical, political, technological or economical is the most important in increasing food production? explain your responds.

i believe that economic factors are the most important compared to the rest of the factors.
Economic factors such as the purpose of farming affects the intensity of food production.

There are two types of farming,substance farming and commercial farming. Substance farming is the production of crops to feed the farmer and his family while commercial farming is the large-scale production of crops intended for sale, rather than to meet the consumption needs of the farmer or the farmer's livestock.

Substance farming uses small pieces of land and where family members of the farmer use simple farming tools and seeds from previous harvest to grow crops , producing low crop yield. For example, in Sub-Saharan Africa, subsistence farming is widely practiced, farmers growing staple foods such a corn and cassava for the family.

On the other hand, commercial farming uses large pieces of land and where hired labourers use machinery such as tractors and combine harvesters, producing high crop yields. For example,  in Europe and Australia, commercial farming is widely practice where crops grow includes animal products such as livestock production, wheat and corn.

The more commercial farming farmers practice, food can be produced more efficiently and thus more food can be produced and sold, intensifying food production.

Although i feel that economic factor is the most important. I also acknowlegde other factors such as technological factors

Technological advances such as (HYVs) are improved strains of crops such as rice, wheat and other cereals that have an increased growth rate . They are developed through cross-breeding of selected varieties which are found to exhibit favorable characteristics. For example, using HYVs can help the crops to ripen at a faster rate, and farmers can practice double or even triple cropping rather then their usual single cropping. It can also produce the best yield from one stalk and the stalk also increase in each rice plant. HYVS also help crops to be more resistant to pest and diseases, hence less crops are destroyed and more crops are yield.
For example, IR8, a variety of HYV rice help the succes in India, which had saved india from famine in the 1960s. The rice enabled farmers to produce twice as much grains and traditional varieties. With the help of HYV, wheat production also increased by a lot, with 4 times more then the traditional. However. These varieties require more water and nutrients to sustain their growth.

Thus economic factor is the most important in increasing food production.

Statement : Which factors physical , political , technological or economical is the most important in increasing food production? Explain your response.

Although the other factors such as physical , political and economical are important . I personally feel that technological advancements is the most important factor in increasing food production .

This is because technological advancements such as Green Revolution can lead to a rapid increase in the productivity of agriculture through the use of Science and technology . For example , high-yielding varieties (HYVs) is developed through compatible cross breeding of varieties. This HYVs have a shorter growing period thus crops can be harvested more quickly . Hence , farmers can then practice double or even triple croppings which will help to intensify food production as more crops can be harvested in a year . The usage of pesticides can kill pests thus preventing the pests from destroying the crops . Herbicides are also used to remove weeds that will compete with nutrients with the crops which will lead to poor crop growth .This reduces the amount of crops that will be destroyed hence this increases the amount of food that can be harvested without being destroyed by pests . Fertilisers can also be used so that the soil is fertile and there is enough nutrients for the crops to grow well . The usage of fertilisers are important because for double or triple cropping to work , the soil must be fertile and not fallow . Irrigation can also be used so that the crops receive sufficient amount of water as water from rain is not enough for farming especially for multiple cropings . Thus , this helps to intensify food production . Hence , i feel that technological advancements are important as physical factors such as rainwater can be replaced by irrigation .

However , i acknowledge that other factors also play an important role in intensifying the food production .

Physical factors such as soil fertility and soil drainage are also important . Fertile soil is generally more ideal for higher crop production . Thus fertile soil which consists of nitrogen , phosphorus and potassium are essential for the plant growth . For example , the highly fertile soils in combination with flat terrains and large water supply in Mekong Delta of Vietnam , result in very high production of rice . Thus , ideal climatic conditions can help intensify food production .

Political factor such as agricultural policy is a policies pertaining to domestic agriculture. Governments decide how limited resources such as money and land may best be used to influence the intensity of food production. For example, governments may choose to channel resources into educating farmers on more efficient ways of farming. Through this programme, farmers were taught about the best available seed varieties, pesticide treatment and irrigation methods for higher food production. Hence, they may use these ways to helps intensify food production.

Economic factor such as agribusiness also plays an important role in food production. Larger companies are able to withstand the impact of changes in the environment, e.g. flooding, compared to small-scale farmers. They have greater financial capacity to absorb losses and are more able to invest in food production, including research to improve output. Therefore, producing crop with greater yield for own commercial farms and this helps to intensify food production.

Thus, I can conclude that technological advancements is still the most important factor in increasing food production because the use of modern farming methods and machines help to reduce physical limitations  and speed up crop growth greatly.

Which factors, physical, political, technological or economical is the most important in increasing food production? Explain your response.

All physical, political, technological and economical factors are able to increase food production. However, physical factors plays the most important role in increasing food production as it has the greatest effect on determining food production. Followed by the economical, technological and political factors, which have less prominent impact on food production.

Physical factors play the most important role in increasing food production. Physical factors such as ideal soils and drainage ability for the various plant types can intensify food production. Fertile soil are rich in minerals essential for plant growth, which are nitrogen, phosphorus and potassium. Fertile soils can be found in floodplains along a river, in deltas at the river mouth and at volcanic areas. In these areas, crop yield tends to be high. For example, the highly fertile soils, in combination with flat terrain and a large water supply in the Mekong Delta of Vietnam, result in very high production of rice. Soils with ideal drainage ability are able to sufficiently retain and drain off water. For example, oats require more sandy soils that are well-drained. In contrast, soils with more clay and which retain large amounts of water are best for growing rice. As the various plant types have ideal soils and drainage ability, the food production can be maximised. Physical factors, also known as natural factors, cannot be modified much to increase food production while others can which means that the location of crops are grown can largely affect its production. With suitable (fertile) soil and proper soil drainage for different types of food, it is very much able to increase food production. Therefore, physical factors are the most important in increasing food production.

Economic factors play the second most important role in increasing food production. Economical factors such as the demand and capital for various plant types can intensify food production. The demand for certain types of food according to the tastes and preferences of consumers affects the amount and type of crops produced, therefore, affecting the intensity of their production. The amount of capital a consumer has, in the form of money or other assets, affects whether a demand can be met. In recent years, more corn has been needed to feed livestock as the demand for meat by a larger and wealthier population increased. As the local population of corn was not able to meet the increasing demand for food for livestock, China, a producer and exporter of corn, started to import corn from other countries such as the United States of America which led to higher crop production in America. With the growing economy in China, they are able to afford these exports that will be used as food for livestock. This shows that with more finances, the living standard of people increase as the the demand of livestock in China increases and is able to pay for exported corn. This maximises the food production. However, the finances one has is varied, countries with greater capital can afford to export more and produce more food while countries with less financial ability cannot. Individuals with stronger financial ability can afford to buy more food, hence, leading to greater demand for food production while individuals with weaker financial ability can only afford to buy a smaller amount of food, hence, leading to a lower demand for food production. Therefore, economic factors are very important in increasing food production but still less important than physical factors.

Technological factors play the third most important role in increasing food production. Technological factors such as high-yielding varieties (HYVs) under green revolution can intensify food production. HYVs are improved strains of crops that have an increased growth rate. They are developed through cross-breeding of selected varieties which have favourable characteristics such as increased resistance to pests and diseases and the ability to grow within a shorter growing season which can increase the number of harvest. For example, IR8. It enables farmers to produce twice as much grain as traditional varieties. By 1990, 70% of the rice and wheat grown in India were HYVs. From 1990 to 2010, rice population multiplied by more than 2 times while wheat production multiplied more than 4 times. This shows that HYVs is able to increase the production of crops significantly. However, such advancements may be costly and not all farmers are able to afford these. Also, HYVs requires more resources such as water, fertilisers to provide nutrients in order to sustain their growth. Therefore, technological factors are quite important but still not as important as economical and physical factors in increasing food production.

Political factors play the least important role in increasing food production. Political factors such as agricultural policy can intensify food production. Agricultural policy refer to policies to domestic agriculture. With more resources provided for agriculture, government may choose to channel resources to educating farmers on more efficient ways of farming. For example, in India, the Punjab Agriculture Department responded in 2012 to the need to ensure greater productivity. Under this programme, farmers were taught about the best available seed varieties, pesticide treatment and irrigation method. With more educated farmers, they would know how to better maximise their food production. This will be a more efficient way in increasing food production as they gain more knowledge on the favourable conditions crops need in order for a healthy growth which will result in increased productivity and more food production. However, resources may be retrained in developed countries as their demand for other needs are higher than agriculture as they can easily export food. Likewise in underdeveloped countries, they would want to sustain other basic needs such as housing and healthcare more than producing more food as producing sufficient food is enough for them to live and the government may not consider the need to educate farmers to increase food production as healthcare and housing may be more urgent issues. Therefore, political factors are the least important factors in increasing food production.

In conclusion, physical factors are still the most important factor in increasing food production as physical factors cannot be controlled as the majority is a natural occurrence and has the greatest effect on crop production. The production of food depend largely on the physical factors which are determined by natural effects that cannot be changed. The other factors, economic, technological and political, also affect food production but not as much as physical factors and these factors can be controlled and changed to benefit food production.

Which factors, physical, technological, political or economical is the most important in increasing food production?

Technogical advancement is the most important factor in increasing food production.

Technological advancement increase crop yield through the green revolution. High-yielding varieties(HYVs) has been introduced. HYVs needs lesser time to maturate. For example miracle rice only needs 130 days to maturate compared to normal crops that needs 170.Theses HYVs also have shorter stems in order to winthstand strong winds reducing loss of crop yield during windy days. In a HYV crop the crops typically have the same height hence this prevents taller crops from blocking sunlight for shorter crops. Maximising the crop yield.
Pesticides have also been introducted to kill pest such as insects and small animals that damage crops. For example arsenic(poison) is used to kill rats that damage crops.This results in more undamaged and healthy crops and increases crop yield. Herbcides have been introduced as well to kill weeds that compete with crops fro nutrients.This ensures that crops grow big and healthy hence increasing crop yield. Fertilisers have also been introduced to provide crops with sufficient nutrients for healthy growth espically in continuously used land. This allows crop to grow more healthly and frequently increasing crop yield.
Lastly irrigation has also been introduced, enhancing crop growth and productivity because water is readily available unlike natural rain. Hence technological advancements is the most important factor in increasing crop yield as it reduces the time need for growing of crops and increase the amount of yield from the crops.

However, other factors such as Physical, Economic and Political also increase food production. But not as much as technological advancement.

One of the physical factor that help increase food production is climate. Climate refers to average atmospheric conditions determined by rainfall and temperatures of a specific place. Climate determimes the type of crops that can be grown and productivity of the land. Plants need minimum of about 130 days above 5°c to grow and mature as sunlight and heat are needed for photosynthesis and germination. However termperature required varies among plants. Crops eg. Peas, broccoli and strawberry require cooler temperatures while soya bean and tomatoes are tolerant of warmer temperature.

One of the economic factors that helps increases food production is agribusiness. Agribusiness invest into food production and research increasing the crop yield. Agribusiness also are financial stable and hence are able to withstand setbacks.Thus agribusiness is not restricted by finance and setbacks and increase food production.

One of the political factors that helps increase food production is agricultural policies. Agricultural policies ensure stable food supply, rice stablility, food quality and employment in agricultural factor. For example, in 2012 in India Punjab Agricultural Department educated farmers on the best seed varities so as to maximise food production in the farm land. Hence agricultural policies increase food production as it educates farmers about the best way to maximise crop yield in their limited farm land.
In conclusion, technological advancement is the most important factor as it has the greatest impact because it affects every country, while physical, political and economic only increases food production in certain countries only.

Which factors, physical, political, technological or economical is the most important in increasing food production?

I feel that the political factor is the most important factor in increasing food production. Although I acknowledge that the economical and physical factors are also factors in increasing food production, I feel that the political factor has the largest magnitude of impact towards increasing food production than the other two factors.

Political factor consists of the ASEAN which is an organisation involving countries in the South-East Asia that helps to intensify food production. Countries part of the ASEAN work together to increase food production by the delegation of different roles to produce food and to fund the operations to increase efficiency in food production. For example, in 2012, Thailand started a programme for other ASEAN nations to intensify rice production so that they can help other countries to increase their efficiency in their food production. Efforts contributed by ASEAN helps the countries involved to increase food production. This has a large magnitude of impact because it affects the regional food production of South-East Asian countries instead of only affecting one area. Therefore, I feel that the political factor is the most important factor in increasing food production.

Economic factor is the purpose of farming that helps to increase food production. There are two purposes of farming: Subsistence farming and Commercial farming. However, only commercial farming will intensify the food production because the large scale production intended for sale are being made. The farming is done on a large piece of land with many hired labours and machinery to produce food more efficiently. For example, production of wheat, corn, tea and coffee are products of commercial farming to be sold. By increasing the number of commercial farming and decreasing the number of subsistence farming, a larger scale of food will be produced efficiently and increases food production. The magnitude of impact of commercial farming is limited because the increase in number of commercial farming cannot be forced to occur. It takes us large amounts of land, more hired labours and more machinery as well which is a lot of a hassle. Hence, the economic factor is not the most important factor in increasing food production.

Physical factor includes proper soil drainage which helps to increase food production. Proper soil drainage can allow the growing of some food to be intensified because they need a specific amount of water to grow well. However, some other food production requires large amounts of water. For example, the growing of rice needs soils with more clay which retain large amounts of water. With the required amount of water for growth, they can be produced more efficiently. Food production can then be intensified by giving crops the ideal soil drainage conditions. However, the magnitude of impact of this factor is also limited because it is not easy to give the crops the ideal conditions to grow well as many other factors may still hinder the production of some food. For example, strawberries can only be grown in cold conditions like the mountainous regions. The soil drainage condition does not have a large impact on food production. Therefore, I feel that the physical factor is not the most important factor in the increasing of food production.

In conclusion, I feel that the political factor is the most important factor in increasing food production because it has the largest magnitude of impact compared to the economic and physical factors.

Which factors, physical, political, technological or economical is the most important in increasing food production?

Technological factor is the most important factor in increasing food production.

Technological factor is the most important factor in increasing food production. Technological advancements allow High-Yielding Variety crops to be grown. HYVs have more growing cycles and ripen at a faster rate. For example, traditional varieties of rice take 180 days to ripen and have only 1 growing cycle each year whereas, High-Yielding Varieties of rice take 100 days to ripen and have 3 growing cycles each year. This allows more crop harvest within each year, leading to increased food production. The success of this is that these High-Yielding Varieties can be used over and over again. Another success is that High-Yielding Varieties allow food production to be high even during extreme weather conditions. The limitation of this is that it is expensive to developed such High-Yielding Varieties.

However, I do acknowledge physical, political and economic factors can increase food production.

The physical factor soils and drainage for the various plant types can help increase food production. The amount and type of nutrients found in the soil varies across locations. Fertile soil is rich in minerals essential for plant growth. At the fertile soils surrounding volcanoes or in floodplains along a river, the crop yield tends to be high. For example, the highly fertile soils, in combination with flat terrain and a large water supply in the Mekong Delta of Vietnam, result in very high production of rice. Soil drainage refers to the ability of the soil to retain or drain off water, where different crops require different soil drainage. For example, oats require more sandy soils that are well drained. Being mindful that different crops receive their ideal amounts and types of nutrients and ideal soil drainage will increase food production.

The economic factor demand and capital for certain types of food can help increase food production. The amount of capital a consumer has affects whether a demand can be met. China used to be a producer and exporter of corn. In recent years, more corn has been needed to feed livestock as the demand for meat by a large and wealthier population increased. Therefore China started to import corn from other countries, causing other countries such as the USA to increase its production of corn for China. Thus because there was a larger demand supplied by China, USA raised its food production in order to meet China’s demand. Therefore, a higher demand will lead to a higher supply, which increases food production.

Political factor can increase food production. Agriculture policies ensure that farmers are educated on farming. For instance, the Punjab Agriculture Department started a programme to educate farmers on the best seed varieties, pesticide treatments and irrigation methods. This allows the farmers to be equipped with the knowledge on efficient methods of farming. Thus, they would choose to use these efficient methods, resulting in more crop harvest on the same plot of land. Hence, increasing food production.

In conclusion, it is apparent that technology is the most important factor in increasing food production because all countries can benefit from the development of a HYV crop, causing it to have a greater impact. In addition, once a HYV crop is developed, it can be used an unlimited number of times, making this a long term solution.

Which factors, economic, technological, political, physical is the most important factor in increasing food production?
Political is the most important factor in increasing food production. The government have the power to decide how resources are used. So as to achieve the highest food production possible, the government holds the deciding power to facilitate resources wisely so that intensification of food can be made possible. One such policy that they have put in place for this to take place is Agricultural Policy. It refers to policies pertaining to domestic agriculture. By deciding how limited resources such as money and land may best be used. As the government decides how the given land and limited money can be used, they play a crucial role in intensifying food production, Government are able to also influence the intensifying of food production by channeling food resources into educating farmers on how to stay relevant by learning the skills to upgrade themselves and more efficient ways of farming. For example, in India, the Punjab Agriculture Development started an education programme where farmers were taught about the best available seed varieties, pesticide treatments and irrigation methods. This will ensure greater productivity from its farmland, which will then result in increase in food production.

Physical factors such as climatic conditions are also important. Ideal climatic conditions for the various plant types can help to increase food production. High temperatures and rainfall int he tropical regions are generally ideal for higher crop production for most crops as the sufficient sunlight and rain throughout the year allows for a long growing season where farmers can grow multiple croppings in a year, thereby increasing food production.Being mindful that crops receive their ideal temperature and rainfall required for growth will intensify food production. But, it has to be noted that some plants require lower temperatures to grow such as strawberries will have to grow in their optimum climate to achieve maximum food production. However, it would be very costly to achieve this process. Hence it is not as important.
Technological advances are also important tin increasing food production as it improves the farming technology which would be able to proliferate food production. Mechanisation is a way which technological advancement have allow farmers to use more advanced machinery to perform tasks which they would otherwise have to do manually. This has sped up the process involved in tending to crops and harvesting. The combine harvester, a machine that harvests grain crops has reduced reliance on human labour. This invention have allowed the process of collecting crops to be more efficient as the machine works faster than a human would be able to. This advancement have greatly reduced the time to collect crops which ultimately intensifies food production as the amount of food supplied at a time is a massive amount. Therefore, mechanism can intensify food production as it warrants a higher rate of production. However, not every country have been equipped with the knowledge to use such equipment, so the government would actually have to educate their native farmers on this before this solution for intensifying food production can be made possible.
Economic also plays a crucial role in increasing food production. Agribusiness is a way in which involves the economy in increasing food production. It is a business or industry involved in food production. It usually refers to large scale farming and related business activities. Larger company which are doing agribusiness are also more able to withstand the impacts of changes in the environment such as damage to crops caused by pets or flooding as compared to small scale farmers. Small scale farmers may not be able to continue after going through such set backs as compared to the larger companies. As large scale company have the ability to afford such researches, they can help to intensify food production and the fact that they can bounce back after setbacks would allow them to intensify food production as they would not close down resulting in the decrease of food supply worldwide. But again, they are under the control of the government and hence they may be restricted to carry out the experiment that they want to. Therefore, political is the most important factor in increasing food production.

Statement: Which factors, physical, political, technological or economical is the most important in increasing food production? Explain your response.
Ans:
I feel that technological advancement is the most important factor compared to physical, political and economical factors as it is the most effective in increasing food production.

Technological advancement such as the Green Revolution is the rapid increase in productivity of agriculture through science and technology. These include, high yielding varieties, fertilisers, pesticides and improved irrigation to enhance farming efficiency. High-yielding varieties (HYV) are improved strains of crops such as rice wheat and maize which have an increased growth rate. They are developed to ripen at a faster rate which produces more croppings per year compared to traditional varieties. HYV also produces more grains per stalk and more stalks, as well as being resistant to pests and diseases. Fertilisers are added substances which provides nutrients for healthy plant growth. Fertilisers would allow soil fertility to be at an optimal level and does not require farms to fallow after a harvest. Pesticides are chemical substances that kills pests which destroy crops reducing the damage to crops.
Irrigation supplies water to the land other than natural means through a network of underground water system. These technological advancements charaterised under the Green Revolution would increase food production by increasing the efficiency of farms.

However I do acknowledge that there are other factors that increase food production.

Physical factors such as the climate and soils and drainage affects food production as well. Climatic conditions that are required for plant growth include high rainfall and high temperatures of 22°C - 32°C are needed. Proper drainage and soil quality is also important as improper drainage can hinder plant growth and infertile soil does not contain the essential minerals for plant growth which decreases the production of food. But having technological advancement like HYV, irrigation and fertilisers, physical factors only play a small role in increasing food production.

Next, economic factors such as demand and capital would also play a part in increasing food production as with a large demand, intensification of food production of that food item increases to meet the demand. Having a larger capital as a consumer would mean that there would be purchasing power and thus increasing the food production of the food item. However without technological advancement to accommodate for the increase in food production, with an increase in demand would not increase food production overall as is reliant on technological advancement.

Lastly, political factors such as the Government Policy - Agricultural policy does have an impact on food production but does not increase food production on a large scale. Agricultural policies influence the intensity of food production by channelling resources and teaching farmers various ways to increase food production. However, these resources are also derived from technological advancement such as fertilisers, pesticides and irrigation. Farmers in India are taught on seed varieties, pesticide treatment and irrigation methods which are all classified by the Green Revolution where HYV, pesticides and irrigation are improved and created.

In conclusion, technological advancement is the most important factor in increasing food production and other factors are only supportive of the technological advancements. Without it, other factors do not hold much impact to increasing food production.

# data[].attributes.body
Which factors, economic, technological, political or physical is the most important factor in increasing food production?

I feel that political is the important factor in increasing food production. Government policy such as agricultural policy can intensify food production. Agricultural policy is the policy pertaining to domestic agricultural where the government are able to influence the intensify food production by deciding how limited resources such as land and money can be used. The government may choose to channel resources into educating farmers on more efficient ways of farming. For example in India, the Punjab agricultural department in 2012, the government started education for the farmers where they are taught about the best available seeds varieties, pesticides treatment and immigration methods. Being mindful to domestics agriculture can intensify food production.

However I acknowledge that other factors such as economic, technological advancement and physical are important in increasing food production as well.

The demand for certain type of food can affect the intensity of their food production. When people  have more money, they demand more food, thus more livestock are reared and more crops are grown to meet the demand. For example, USA increased its production of corn to export to China to feed livestock and in turn, more livestock can be reared for meat. Being mindful that demands are met can intensify food production.

Improvement n farming technology can intensify food production. Cross breeding method is used to develop high-yielding varieties, they are found to exhibit favourable characteristic which include increased resistance to pests and to diseases for the ability to grow within a shorter growing season so that there can be more harvest in a year. For example, "Wonder Rice" has a growing season of 100 days as compared to they growth duration of 120 days for the non HYVs and the ZR36 has a maturation period of 105 days instead of 130 days for previous HYVs and 150 days for traditional varieties of rice. Being mindful to technological advancements can intensify food production.

Ideal relief for various plant type can increase food production. Slopes are cut to create flat land for cultivation, this prevent topsoil from being eroded as steep relief will remove topsoil which is fertile. This way not only we can prevent topsoil being removed, we can also retain water that is needed for certain plant growth. For example, crops that are grown on terraces which includes the Longji Rice terraces in China, Sapa in Vietnam and Banoue Rice Terraces in Philippines. Being mindful that crops receive sufficient nutrients and water required for growth will intensify food production so slopes are cut to create flat land for cultivation.

However, I strongly feel that political is the most important factor in increasing food production. Without the government, no one will be managing the activities taking place and funds will not be provided to educate the farmers with the required knowledge. Hence,  even with good climatic conditions,advanced technology and demands being met, if the farmers are not educated in the areas of farming, they will not be able to fully make use of the land to grow the maximum yield of crops which means the food production will in turn lower than the actual amount that the land can actually produce. Therefore, political is the most important factor in increasing food production

Statement:which factors physical,political technological or economical is the most important in increasing food production?Explain your response.
While the other factors,such as political,economical and technological factors are important,I personally feels that physical factor is the most important factor in increasing food production.
Firstly, physical factor is the most important factor in increasing food production.
Soils and drainage is one point for physical factor.It has ideal amount and type of nutrients found in the soil varies across locations can help increase food production.Fertile soils can be found in floodplains along a river,in deltas at the river mouth and in areas near volcanoes. In those areas, crop yield tends to be  high. For example,the highly fertile soils,in combination with flat terrain and a large water supply in the Mekong Delta of Vietnam, result in very high production of rice. Therefore, physical factor is the most important factor as without it, no matter how good the other factors are, crops cannot grow without proper soil and drainage.
Secondly, economic factor is also important  factor in increasing food production. Demand of capital is ideal of amount of capital a consumer has, in the form of money or other assets, affects whether a demand can be met. As the local production of corn was not able to meet the increasing demand for food for livestock, China started to import corn from other countries such as USA. As China's population grew in wealth, this allowed for demand for more meat to be met. Hence ,USA increased its production of corn for export to China to feed livestock. In result, more livestock can be rested for meat. Hence,economic factor is also important  factor for the increase in food population as without capital people cannot purchase food from other countries to increase the food population
Thirdly,Political factor is also important to increase food population.Agricultural policy is an ideal stability of food supply as well as whether people have sufficient resources to gain access to it. By deciding how limited resources such as money and land may best be used,governments may choose to channel resources into educating farmers or more efficient ways of farming. Hence,political factors is also important as without the help of government many things cannot be done as other people would not have the resources.
In conclusion,physical factor is the most important factor as it is the basic that leads to increase in food production. Without the physical factor,food production cannot work normally.Not only that,other factors need the help of more resources which may be more difficult than physical factor.

Statement: Which factors, physical, political, technological or economical is the most important in increasing food production? Explain your response.

Ans:

While the other factors, such as the political, technological and economical factors are important, I personally feel that the physical factor is the most important in increasing food production as it gives the most impact and is also one of the most effective way to increase food production.

Firstly, for physical factor, I feel that climate is the main factor and plays the most important role in increasing food production. Ideal climatic conditions can help increase food production. Proper temperatures, rainfall, amount of sunlight, together with low rate of climatic hazards will provide an ideal condition for crops to grow. Only with a suitable climate, will the crops be able to grow well and be of good quality. For example, strawberries requires low temperatures to achieve maximum crop yield. With high quality crops, people will want to buy more and increasing the demand and need to grow more food → more crops being produced and hence the increased production of food.

Secondly, I feel that the technological advances in yielding crops does play an important role in increasing food production, but not the most important. Green revolution characterised by high-yielding varieties; fertilisers; pesticides; improved irrigation and mechanisation will help improve and upgrade the living conditions of crops and help improve and sustain growth of crops which results in an increase in crop harvest and thus increasing food production. For example, improved corn varieties have been grown in Africa even though corn is not indigenous to it. Corn production in developed countries such as England has increased as well. Thus, technological advancement does help increase food production but it has only a moderate impact on increasing food production, which is dependent on the climate, as no matter how advanced the technology is, if there is a flood, tropical cyclones or thunderstorm, it could destroy all the high-tech machinery and technology and destroy the crops and its surroundings. This will in turn, decrease food production.

Thirdly, another factor that is quite important but not the most is economic -- demand and capital. The higher the demands for food, the higher the production of food. When people have more disposable income, they have more purchasing power, and are allowed to have a larger variety and preference of food, and so they will eat more, there will be an increase in demand which results in increase in need to grow food → increase food production. For example, as China’s population grow in wealth, this allows the demand for more meat which increases the production of corn in USA for export to China to feed livestock. Hence, the higher the demand and capital, the higher the production of food. However, similarly to the advancements in technology, no matter how rich the consumers get, one flood could destroy all the crops and the food production would be zero, where the farmers have to start from scratch.

In conclusion, physical factors -- climatic conditions are the most important factor in increasing food production, as it is the foundation for increasing food production as the other factors are builded on top it. Only when there are no climatic hazards, the climate is safe, is the other factors able to contribute to increasing food production and function normally. Hence, since the physical factor has the largest impact and does not need to count on the other factors, it is the most important factor in increasing food production.

Which factors, physical, political, technological or economical is the most important in increasing food production? Explain your response.

The physical factor is the most important factor among the rest because climate, one of the physical factor, holds the highest weightage in terms of affecting increasing food production. It is able to influence the increase of food production the most as compared to factors like politics, technology and economic due to it playing a huge role.

Ideal climatic conditions for the various plant types can help increase food production. High temperatures and rainfall in the tropical regions are generally ideal for higher crop production for most crops as the sufficient sunlight and rain throughout the year allows for a long growing season where farmers can grow multiple cropping in a year, thereby increasing food production. For example, in the Republic of Kosovo, a country in southeastern Europe, precipitation falls as rain and continues through the winter as snow, depending on the altitude of the area, from September to May of the following year. Land preparation and sowing takes place from April to June after which harvesting takes place during the drier months of June to August. However, during long winters, food production can only occur during the warmer seasons when temperature and rainfall are suitable for growing crops. As humans are unable to control how the climate would be like, the food production would be highly dependent on the climate of the country. If the climate is suitable for growing a certain crop, the food production of the crop would be high, however if the climate is not suitable for growing crops, the food production of the crop would be low as the crops are unable to grow due to the unfavourable conditions. Hence, the physical factor which is the climate is the most important in increasing food production as the climate affects the suitability of growing the crop in a certain area.

However, I still acknowledge that other factors can help to intensify food production.

One of the political factors, the Association of South Asian Nations (ASEAN) is an organisation of 10 Southeast Asian countries. ASEAN aims to accelerate the region’s economic growth, increase social progress, foster cultural development and protect regional peace and stability. For example, in 2012, Thailand started a programme for other ASEAN nations to intensify rice production in the region. The countries that are part of ASEAN will work with or help other countries when other countries are in crisis. When other countries are in need of help, the countries helping them would need to produce more food to be able to give to the countries in need of help. Hence, the food production will increase as they are not just producing food for their own citizens but also for other countries.

The Green Revolution has caused an increase in the food production due to the use of Science and technology. For example, high-yielding varieties (HYVs) is developed through cross-breeding of selected varieties which are found to exhibit favourable characteristics. These include increased resistance to pests and diseases or the ability to grow within a shorter growing season so that there can be more harvests in a year. However, these varieties require more water and nutrients to sustain their growth. Wonder Rice has a growing season of 100 days as compared to the growth duration of 120 days for the non-HYVs. Farmers can practise double or triple cropping using the same piece of land, allowing more crops to be harvested and hence, intensifying food production.

One example of economic factors is the demand and capital. The demand for food changes according to tastes and preferences of consumers. This affects the amount and types of crops produced. The amount of capital a consumer has in the form of money affects whether a demand can be met. For instance, China used to be a producer and exporter of corn. In recent years, more corn is needed to feed livestock as the demand for meat increases as the population grows larger and wealthier. As the local population is unable to meet the increasing demand for livestock, China imports corn from other countries like USA. USA has to increase production of corn for export to China to feed livestock, which in turn, result in more livestock that can be reared for meat. This causes an increase in the food production in order to supply more food for the increasing population.

Even though I acknowledge that other factors such as the technological advancements, political and economic factors are able to help to increase food production, I still think that the physical factor is still the most important factor that helps to increase food production. With the advent of technology, mechanisation are able to speed up the process of harvesting, sowing, and therefore giving more time for crops to grow. With more money, the country is able to buy higher quality fertilisers to help grow more quality crops. With the help of other countries, countries are able to get extra help from other countries. However, once the climate is not suitable for growing crops in an area, the crops would not be able to grow or may die off quickly. Hence, even with more money or machines there would not be any crops for them to even harvest. Therefore, I still think that the most important factor would be the physical factor.

Political Factors
The government decides how limited resources such as money and land may best be used; they are also able to influence the intensity of food production. Governments may choose to channel resources into educating farmers on more efficient ways of farming. In India, the Punjab Agriculture Department responded in 2012 to the need to ensure greater productivity from its farmland. For a country to ensure a stable supply of food, it has to ensure that food is readily available to its population. Hence, importing food from different countries is a way to diversify the sources of food supply. Instead of relying on a few countries for food, more food suppliers are sourced from more countries to buffer against food shortages and price fluctuations. This then resulted in more food is being able to be produced and more food is readily available for consumption by the people.

Which factors, physical, political, technological or economical is the most important in increasing food production? Explain your response.

While factors such as technological and economical factors are important in increasing food production, political factors still hold the most importance as they influence and determine the impact of other factors.

( Megan do the first political para part plus add some parts here and there in the answer like however, ....... factor is also important but still plays a larger/smaller role or something like that)

The increase in the demand for food and growth of agribusiness in the economies of countries increases food production. The increase in food demand drives the growth of agribusiness, which leads to an increased food production through a rise in commercial farming and development of more high-yielding crops to meet the demand. One example is China, which's growing economy led to the increase in demand for meat products. This led to the increase in demand for corn to feed to livestock for meat products and resulted in China having to import corn from other countries such as the USA to meet the growing demand. This then resulted in the increase in demand for corn in the USA, leading to an increased production of the crop to meet the demand. To meet the growing demands for food, food production is increased.

The increase in technological advancements have also improved the food production process which has allowed in the increase of food production. Some of the advances include high-yielding varieties, use of fertilizers, pesticides and herbicides, irrigation and mechanization. Fertilizers enhance plant growth by enriching the soil with nutrients which high-yielding varieties require more of, pesticides and herbicides kill insects and small animals and unwanted weeds respectively that can destroy or damage crops, irrigation helps supply water to dry areas or during dry seasons where precipitation to water the plants is insufficient and mechanization speeds up the farming process by taking over manual labor in the farm, saving time to grow more crops. High- yielding varieties are improved strains of crops that have an increased growth rate and resistance to bad weather and pests, increasing the crop harvest. One example is the IR8 rice, which allowed farmers to product twice as much rice as traditional varieties, saving India from famine in the 1960s. The de

i strongly believe that economic factor is the most important. Economic factors include purpose of farming, agribusiness and demand and capital.
There are two types of farming subsistence farming and commercial farming. Substance farming is the production of crops to feed the farmer while commercial farming is the large-scale production of crops intended for sale, rather than to meet the consumption needs of the farmers or the farmer's livestock

Account for the trend of undernourishment between 1990 and 2005 in the respective country groups. [5]

The prevalence of undernourishment in the total population in country groups of Sub-Sahara Africa, South-East Asia and Central America have all decreased from 1990 to 2005. Sub-Sahara Africa has dropped by 3% from 32% in 1990 to 29% in 2005. South-East Asia has dropped (use "decreased") by 8% from 24% in 1990 to 16% in 2005. Central America has dropped by 5% from 19% in 1990 to 14% in 2005.
This is caused by the increase in disposable income in the 3 country groups. Due to the increase in disposable income people in the 3 country groups would have more purchasing power for more and different food. The access to more and a larger variety of food provides more nutrients for the people in the 3 country groups. Hence this decreases the amount of undernourished people.
Another reason could be because the 3 country groups are more educated about the health concerns that conventional methods of growing food brings, such as the risk of cancer from the use of pesticides on farmland. Hence the people of the 3 country groups would choose to eat organic food avoiding consumption of the potentially harmful pesticides used during the food production process.This leads to a decrease in undernourishment as people who consume organic food are healthier as they take in more nutrients from eating organic food compared to non-organic foods.

In order to mitigate the strain on food shortage, all physical, political technological and economical factors are essential to intensify the food production. However, physical factors play the most important role in increasing the output to tackle with such problem.

Terracing steep slopes is one of the physical factors that creates a suitable environment for farming and helps intensify food production.

Account for the trend of undernourishment between 1990 and 2005 in the respective country groups. [5]

The prevalence of undernourishment in the total population in the 3 country groups -- Sub-Sahara Africa, South-East Asia and Central America has been decreasing in general from 1990 to 2005.                  Sub-Sahara Africa has dropped from 32% to 29%, South-East Asia from 24% to 16% and Central America from 19% to 14% from 1990 to 2005.

The cause for this trend is due to economic factors like disposable income and socio-cultural factors such as food preferences. The people living in these 3 country groups have an increase in disposable income. Disposable income is the amount of income left to an individual after taxes have been paid. With an increase in disposable income, people would have more purchasing power to consume a larger amount and variety of food, especially the food that is more expensive but has more and certain health benefits and nutrients. One example would be a country with a similar trend --- Taiwan. In 1959 to 1991, Taiwan has experienced high economic growth causing their people's disposable income to increase, which led to their meat, fruit and fish consumption to be increased by four times, five times and two times respectively.

Another reason is food preferences. People in the 3 country groups are slowly starting to know more about the health concerns about conventional methods of growing food, such as the risk of cancer from the use of pesticides. So, they start to choose to eat more organic food. When more organic food is been eaten, there are more nutrients that are taken in, people get healthier and they eat more. This decreases the number of people who are undernourished.

Account for the trend of undernourishment between 1990 and 2005 in the respective country groups. [5]

The prevalence of undernourishment in the total population between 1990 and 2005 decreased generally. The prevalence of undernourishment for Sub-Sahara Africa decreased from 32% to 29%, while the prevalence of undernourishment for South-East Asia decreased from 24% to 16% and the prevalence of undernourishment for Central America decreased from 19% to 14% between 1990 and 2005 in all three country groups.

This decrease in the prevalence of undernourishment is due to the increase in disposable income in all the three country groups, thus they will have a higher purchasing power to consume a larger variety and amount of food. Hence, when they have more amount of food to eat, they will not be undernourished as the foods which they can afford gives them the nutrients they need. Therefore, there will be a decrease in the prevalence of undernourishment between 1990 and 2005 in all three country groups.

Another reason for the decrease in the prevalence of undernourishment Ian due to globalisation. Globalisation makes it possible to set up more fast food chains in many countries, thus the quality and price are fixed in the fast food chains, selling food at a cheaper price than local outlets. Thus, making it more affordable to people and hence allowing them to have the nutrients they need and therefore there is a decrease in the prevalence of undernourishment between 1990 and 2005 for all three country groups.

Account for the trend of undernourishment between 1990 and 2005 in the respective country groups. [5]

Generally, the prevalence of undernourishment in total population has decreased over the years from 1990 to 2005. In Sub-Sahara Africa, the percentage of undernourishment decreased from 32% at 1990 to 29% at 2005. In South-East Africa, the percentage if undernourishment also decreased from 24% in 1990 to 16% in 2005. Also, the percentage of undernourishment in Central America decreased from 19% to 14% from 1990 to 2005.

All these decreases in undernourishment in these country groups may be due to higher disposable income over the years from 1990 to 2005. Disposable income is the amount of income left to an individual after taxes have been paid. Higher disposable income has resulted in higher consumption of food across the world because they are more financially affordable for the food. So, by being able to afford larger amount and variety of food to nourish themselves with good nutrients, there is a decrease of undernourishment across the countries from 1990 to 2005.

Account for the trend of undernourishment between 1990 and 2005 in the respective country groups. [5]

From 1990 to 2005, there is an overall decrease of undernourishment in both LDCs and DCs. For example, in Sub-Sahara Africa, there is a decrease of prevelance of undernourishment from 32% to 29%. In South East Asia, the prevelance of undernourishment plunged from 24% to only 16%, and Central America decreasing from 19% to 14%.

The reason for the overall trend of the decrease of undernourishment could be due to more disposable income from the country groups mentioned. As the economic situation of the country gradually climbs, more families can now afford to have jobs and thus having more disposable income as they are financially capable of supporting their family members. Having more disposabke income means that more people will have the purchasing power to buy a wider variety of food, which means that the different types of food bought will each have its own nourishing purposes. As consumers consume the food, they will have more nutrients in their body than before, making the properly nourished. Thus, there is a decrease in undernourishment in the area mentioned.

From 1990 to 2005, there is a general decrease in percentage of undernourishment. In Sub-Sahara Africa, there is a decrease in percentage from 32% to 29%. In South-East Asia, it decreased from 24% to 16%. In Central America, the decrease in percentage is from 19% to 14%.

This can be because of the increase in disposable income in those country groups. Having more disposable income means more purchasing power to consume a larger amount and variety of food. Hence, lesser people will be under nourish as eating a variety of food will have different vitamins and nutrients in their body. Therefore, this explains the decrease in percentage of undernourishment.

the prevalence of undernourishement in the total population in sub sahara africa, southeast asia and central america has decreased over the years from 1990-2005. in 1990-1992 and 1995-1997, sub sahara had 32% of prevalence of undernourishment. but from 2003-2005, it decreased from 32 -29%. for southeast asia, the percentage of prevalence of undernourishment in 1990-1992 decreased from 24% to 18% in 1995-1997. it then decreased again from 18% in 1995-1997 to 16% in 2003-2005. in central america. the percentage of prevalence of undernourishment decreased from 19% in 1990-1992, to 18% in 1995-1997. it then decreased from 18% in 1995-1997 , to 14% in 2003-2005.

This is because the countries are becoming for economically developed  from 1990-2005. This results in higher disposable income and they have more purchasing power to consume a larger amount and more variety of food.With the ability to purchase more food that have more nutrients and they will not be undernourished as the food the eat gives them the nutrients they need.
Thus there is a decreased in prevalence of undernourishment in total population in sub sahara, southeast asia and central america.

The prevalence of Undernourishment in the total population has decreased from 1990-2005 by 3% in Sub-Sahara Africa, by 8% in South-east Asia and by 5% in Central America. This could be caused by an increase in the Disposable income in the respective countries. With higher disposable income, the countries will have more money and the ability to spend on a larger amount of food and the variety of food choices, meeting the demands of the people. With the finances to spend on food, the respective countries would also be able to afford better food with more nutrients and health benefits. Hence, more people will be able to have sufficient food and nutrients, decreasing the percentage of undernourishment in the country.
Another factor that could have contributed is the stability of food supply. The government of the country could have taken action to increase food production in the country by increasing the use of Agriculture land through expanding the areas used for agriculture. With an increase in harvests, there will be more food to provide for the country and more people will also get food and nutrients from eating these organic food grown in the country. Therefore, stabilising the food supply could also be another possible reason for the decrease in undernourishment.

The prevalence of undernourishment in total population in Sub-Sahara Africa, South-East Asia and Central America has decreased. From 1990-1992 and 1995-1997, Sub-Sahara Africa had 32% of prevalence of undernourishment. However, from 2003-2005 the prevalence of undernourishment in total population decreased to 29%. The prevalence of undernourishment in total population in South-East Asia has also decreased from 24% in 1990-1992 , 18% in 1995-1997 to 16% in 2003-2005. The prevalence of undernourishment in total population in Central America also decreased from 19% in 1990-1992, 18% in 1995-1997 to 14% in 2003-2005. Both South-East Asia and Central America's  decreased in  prevalence of undernourishment in total population  throughout the years. but Sub-Sahara Africa's prevalence of undernourishment in total population stayed constant in 1990-1992 to 1995-1997 and decreased only in 2003-2005. I believe that there was an decrease as people in the country groups could have gained knowledge of having a healthy diet throughout the years and chose to use their money on food that are rich in vitamin such as fish instead of purchasing fast food.

This may be because the three countries are becoming more economically developed from 1990 to 2005. There is higher disposable income and greater purchasing powering the population.Thus, the people will be able to afford a greater amount of food which tends to have less nutrients that may affect their health conditions.

I feel that technology advancement is the most important factor in increasing food production. Food production is the process of transforming crops or livestocks into marketable food products. Increasing food production allows everyone in the world to have adequate amount of food to prevent starvation, especially in less developed countries (LDCs).

Technological advancements such as the Green Revolution. Green Revolution refers to the rapid increase in the productivity of agriculture through the use of science and technology. The Green Revolution is characterised by high-yielding varieties, fertilisers and pesticides, improved irrigation and mechanisation. High-yielding varieties ripen at a faster rate while the traditional varieties take a longer time to ripen. Hence by using high-yielding varieties with other technology, farmers can practise double or even triple cropping instead of using the traditional varieties which only one crop can be harvested and grown every year. The usage of pesticides is also another way to increase food production. With the presence of pesticides, pests that are potentially able to harm the crops will be killed and hence the amount of crops being destroyed is decrease,  leading to a higher output per unit area. However, without the use of pesticides, the pests will be able to destroy crops and leading to a decrease output per unit area. Hence, i feel that technological advancement such as the Green Revolution is the most important factor as it can increase the food production in many different ways and when all the characteristics of Green Revolution work together, they can produce the maximum amount of food.

Although, there are other factors which can affect the increase in food production such as the government policy which includes agricultural policy and food policy. A government policy is a plan of action by government in order to change a specific situation. Agricultural policy refers to the policies pertaining to domestic agriculture. The government decides how resources like money and land can be best used to improve the rate of food production. For example, government may choose to educate farmers on efficient way of farming instead. Food policy refers to a decision made by a government that affects how food is produced, processed, distributed, purchased and packages. As part of the government policy, food policy helps to ensure food security. Some of the ways to ensure food security include food stockpilling and diverisifying the source of food supply. Stockpilling is the setting aside and storage of food to ensure food security during emergencies. By stockpilling, government would still be able to provide food their population should there be situations of food shortages or price increase of food items.

In conclusion, all the factors have to work together to maximise food production. However I still strongly believe that technological advancement like Green Revolution is the most important factor as it can benefit the world the longest compared to the other factor. As technology is very advance now, technology will be more advanced in the future and hence increasing the amount of food production in the shortest period of time.

The 3 countries have an overall decrease in the prevalence of undernourishment in the total population between 1900 and 2005. From 1990-1992, Sub Sahara Africa, South East Africa and Central America have 32%, 24%, 19% for the prevalence of undernourishment in the total population respectively. From 2003-2005, Sub Sahara Africa, South East Africa and Central America have 29%, 16%, 14% for the prevalence of undernourishment in the total population respectively. This shows that Sub Sahara Africa, South East Africa and Central America have a 3%, 8%, 5% decrease from 1900-2005 therefore resulting in the overall decrease in the prevalence of undernourishment in the total population in the 3 countries.

This could be due to the lack of disposable income in the countries. Disposable income in the countries in 2005 is much lesser than in 1990 as the quality of life improves, the people will have to pay more for taxes thus, lesser disposable income to spend on a larger variety of food which will lead to undernourishment.

Another reason why these countries are undernourished is because of population growth. As the population increases uncontrobally due to lack of family planning, the demand for food increases. However due to the lack of supply, these countries are unable to feed much to the people thus, they will be undernourished.

The prevalence of undernourishment in the total population between 1990 and 2005 is decreasing in the three countries. From 1990 to 2005, Sub-Sahara Africa has a decrease in undernourishment by 3%, South-East Asia has a decrease in undernourishment by 8% and Central America has a decrease in undernourishment by 5%. This may be because these three countries have been more economically developed now thus people will have higher disposable income. With the increase in disposable income, these people will have more purchasing power to buy more amount of food. As people have more amount of food to eat, they will not be undernourished because the food they eat give them the nutrients that they need. Hence, there is a decrease in the prevalence of undernourishment in the total population of Sub-Sahara, South-East Asia and Central America.

From 1990 to 2005, the prevalence of undernourishment in total population of the three countries are decreasing. For the Sub-Sahara Africa, the prevalence of the undernourishment decreases 3% from 190 to 2005. For the South-East Asia, the prevalence of undernourishment decreased 5% from 1990 to 2005. For Central America, the prevalence of undernourishment decreased 8% from 1990 to 2005.The prevalence of undernourishment in the three countries are decreasing due to the amount of disposable income increasing. As the amount of disposable income increases, the people will tend to be able to afford more food to consume. People that have higher disposable income can also afford to buy organic food that is more expensive. Organic food have not been processed hence, people with higher disposable income will be able to consume organic food to prevent themselves from undernourishment. Hence, this is why the prevalence of undernourishment is decreasing in all 3 countries.

The prevalence of undernourishment for the total population for the three countries, Sub-Sahara, South-East Asia and Central America have a decreasing trend. For example, for Sub-Sahara, the prevalence of undernourishment for the total population decreased from 32% to 29% from 1990 and 2005. During the same duration from 1990 to 2005, the prevalence of undernourishment for the total population in South-East Asia decreased from 24% to 16%. For Central America, the prevalence of undernourishment for the total population decreased from 19% to 14% from 1990 to 2005.

The drop in the percentage can be due to the increase in disposable income by the people. These people who have more disposable income are able to spend more money on a larger variety and amount of food. The quality of food consumed by them will also increase. The food consumed have certain health benefits, like in organic food, and enough essential nutrients that are required to have in the body. Therefore, since there are more people who are able to purchase more healthy food, which are usually more expensive, can prevent themselves from undernourishment.

The prevalence of undernourishment for total population in all 3 country groups have been decreasing between 1990 and 2005. From 1990 to 2005, the prevalence of undernourishment for total population of Sub-Sahara Africa, South-East Asia and Central America have decreased 3%,8% and 5% respectively. This implies that there is an increase in disposable income in all 3 countries. Disposable income refers to the amount of income left to an individual after taxes have been paid. When disposable income increases, people will have more money to spent on higher quality food as they  are able to afford them. When higher quality food becomes affordable, more can be purchased which implies that people are consuming food with more nutrients. This shows that people are eating healthier and therefore causes a decrease in the prevalence of undernourishment for the total population of the 3 countries. Another factor that is pricing. When the pricing of food decreases, people will be able to afford more amount of food with their disposable income. When amount of food purchased increases, this implies that people are able to afford food and not starving themselves. This shows that people are eating the amount of food needed to survive. Therefore, leads to a decrease in the prevalence of undernourishment for the total population of the 3 countries

From 1990-205, there is a decrease in percentage of undernourishment in total population for all 3 countries. This can be seen from the data from 1990-2005, the undernourishment percentage of South-East Asia decrease from 24% to 16%. And For Central America, there is a decrease in percentage from 19% to 14%.  This might be due to the rise in disposable income in these countries thus having people with lesser income being able to afford food with more nutrition to have more nutrients, which prevents them from being undernourished. Therefore there is a decrease in percentage of undernourishment people. Another reason may be due to the people preferring to consume fast food. As fast food restaurants are set up at almost every countries, most people will be able to have access to these fast food restaurants. Due to its affordable pricing, many people are able to afford these fast foods. This causes lesser people to be undernourishment as they consume food which are better compared to what they consume with lesser nutrients before. Therefore, this leads to lesser percentage of people undernourished.

Which factors, physical, technological, political or economical is the most important in increasing food production?

Technogical factor is the most important factor in increasing food production.

Technological factor improve farming technologies such as using fertilisers, pesticides, irrigation, high yeilding varieties and mechanisation. High yielding varieties are developed thorugh cross breeding of selected varieties which are found to exhibit favourable charactiristics such as increased resistance to pests and diseases. An example if HYV rice is the IR36 rice that have a maturation period of 105 days instead of 130 days. This shows that more crops can be produced in a year as more crops can be harvested per year due to the decrease in number of days needed to produce these crops.

However, other factors such as Physical, Economic and Political also contribute to the increase in food production. But not as much as compared to Technological factor.

One of the physical factor that help increase food production is climate. Since temperature and rainfall affects the rate of photosynthesis and seed germimation, not all crops are able to grow in certain regions of the world. An example is corn must be cultivated in countries with temperatures of 18-20 degree celcius during certain season of the year. Thus the increase in food production in all countries are seasonal as different country have different temperature for different crops to grow.

One of the economic factors that helps increases food production is purpose of farming. There are 2 types of farming, subsistence and commercial. Subsistence farming's main purpose to feed the family while commercial farming is to mass produce an amount of crops for people's demand. An example is family members in Madagascar tiling the soil to prepare farming to support themselves. While in Spain, big machines such as tractors harvests large amount of crops. Thus not all country have the same purpose of farming to increase food production as there are other purpose such as subsistence farming, will not affect the increase in food production.

One of the political factors that helps increase food production is ASEAN. ASEAN aims to accelerate the region's economic growth, increase social progress, foster cultural development and protect regional peace and stability. An example is an agreement with China, Japan and South Korea in 2011 October to ensure food security for its members. They supply rice for one another for a reserve in times for natural disasters. Thus this factor only affects country in certain region and not all countries are involved in this agreement. This shows that the increase in food production is not in a global scalr but instead a region only.

In conclusion, technological factor is the most important as all countries in the world uses it, while for physical, political and economic only helps increases the food productions in certain parts of the world only.

Account for the trend of undernourishment between 1990 and 2005 in the respective country groups. [5]

From 1990-2005, the prevalence of undernourishment have been decreasing in all 3 countries. In Sub-Sahara Africa, the percentage of undernourishment decreased by 3% over the years. In South-East Asia, the percentage decreased by 8% in total over the years. Lastly, in Central America, the percentage of undernourishment decreased by 5% over the period of years.
The decrease in percentage is because of the growth of income of each family, which leads to higher disposable income of each family, with the higher disposable income of the families, they are entitled to better quality meals, with the ability to afford better meals, they would not have to starve and can have sufficient nutrition, this result in the decrease of percentage of prevalent undernourishment in all 3 countries as people are able to get sufficient nutrition.
The decrease can also be caused by globalisation because at that point globalization was not yet that advance, however, with the developments over the years, it brings a plethora of benefits to almost every countries, this includes food being available at a lower cost, which increases the affordability of food. This would enable more people to be able to purchase food, hence, lesser people would starve and more would be nourished. This explains the decrease in percentage of prevalent undernourishment in all 3 countries.

Account for the trend of undernourishment between 1990 and 2005 in the respective country groups. [5]

Generally, from 1990 to 2005, there was a decrease in percentage of undernourishment. For Sub-Sahara Africa, the percentage of undernourishment in the population decreases from 32% to  29%, from 1990 to 2005. From 1990 to 2005, for South East Asia, there was a decrease in percentage of undernourishment of total population from 24% to 16%. From 1990 to 2005, for Central America, there was a decrease in percentage of undernourishment of total population from 19% to 14%.

One reason why all three country groups have a decrease in percentage of undernourishment of total population is because of increase in disposable income -->increase in purchasing power--> able to buy more food and food with more nutrients--> decrease in people unable to afford better food with more nutrients--> decrease in percentage of undernourishment in the population.

Another reason why all three country groups have a decrease in percentage of undernourishment of total population is due to globalization. Globalization--> possible to set up fast food chains in many countries-->quality and price are fixed in fast food chains--> usually sold at a cheaper price than local outlets--> people would be able to afford-->prevent themselves from starving and lacking nutrients-->decrease in percentage of undernourishment in the population.

From 1990-2005, the amount of undernourishment has decreased for the three regions, Sub Sahara Africa, South East Asia and Central America. (Gd general trend) Sub Sahara Africa received a drop( use "decrease")in undernourishment by 3%, South east Asia received a drop of 8% and Central America received a drop of 5%.( pls state time frame) This is probably due to the increase in disposable income when people have more money(use "purchasing power")to buy more food ,thus this reduces the chance of undernourishment which leads to a decrease in undernourished people(gd attempt to link)

The prevalence of undernourishment in the total population of Sub-Sahara Africa, South-East Asia and Central America has decreased between 1990 and 2005.(gd use of general trend)The prevalence of undernourishment in the total population in Sub-Sahara Africa has decreased 3% from 32% in 1990 to 29% in 2005. The prevalence of undernourishment in the total population in South-East Asia has decreased 8% from 24% in 1990 to 16% in 2005. The prevalence of undernourishment in total population in Central America has decreased 5% from 19% in 1990 to 14% in 2005.(+gd description of trend, incorporating TAD)

This may be because the three countries have been developing (use "more economically developed now")between 1990 and 2005. There is higher disposable income and greater financial power(use"purchasing power" instead)in the population hence the people will be able to afford a greater variety and amount of food which provides them with necessary nutrients(pls link to reduced % of undernourishment).

Which Factors, economic, technological, political, physical is the most important factor in increasing food production?

There are many factors that are essential in intensifying food production, however in my opinion, Technological Advancements is most important factor in increasing food production. The Green Revolution, one of the technological advancements in agriculture, can help to rapidly intensify food production with the use of science and technology.

High-yielding varieties are improved strains of crops such as rice, wheat and other cereals that have an increased growth rate, developed through cross-breeding with other varieties of favorable characteristics, such as resistance to pests and diseases or the ability to grow within a shorter growing season, these characteristics ensure that the food production is not hindered by external factors. One example of how it intensifies food production is that the characteristics of the crops after cross-breeding allows it to grow within a shorter amount of time, hence, contributing to higher crop yield in a year. For example, IR8, it is a variety of HYV rice, saved India from famine in the 1960s, this rice enables farmers to produce twice as much grain as traditional varieties. Thus, technological advancements like High-yielding varieties are the most important factor to intensifying food production as with the help of technological advancements, limitations in farming such as the duration to grow the crops can be overcome by quickening the process.

Other factors such as Agribusiness is also essential as they have the economic ability to invest into research and development in food production which is important in intensifying food production. Agribusinesses place importance on scientific and business principles in farming by investing in the research and development of food crops.  With such investments and resources, farmers and companies will be able to do more to get greater crop yield for business purposes. For example, by investing into research, researchers will have more resources for their research to find developments and solutions to protect their crops from pests and flooding and therefore gaining greater crop yields as lesser crops will be destroyed by pests and floods. Hence, other factors like agribusiness is also important in increasing food production.

However, although I acknowledge the importance of agribusiness, I still agree that technological advancements are still more important in increasing food production because even after researching, the companies would still require technological advancements to help in their commercial farming to increase the crop yield.

Another Factor such as the Physical factor is also important as the environment and nature plays a fundamental role in crop production. For instance, locations with suitable soil and good water drainage for the various plant types can help in increased food production. Locations with fertile soil are generally ideal for high crop yield as these soils are rich in minerals and contains more nutrients essential for plant growth, hence, it can be very helpful to increasing production of food. For example, the highly fertile soils, in combination with flat terrain and a large water supply in the Mekong Delta of Vietnam, results in very high production of rice.

Having proper soil drainage is also important as it prevents flooding and drought and improper soil drainage can hinder the growth of crops. For example, oats require more sandy soils that are well-drained. In contrast soils with more clay and which retain large amounts of water are best for growing rice. Therefore, being mindful of fertile soil and proper soil drainage for the various plant types will intensify food production.

However, although I also acknowledge the importance of the physical factors in increasing food production, there are limitations in the environment when it comes to growing crops, for instance, the time taken to grow the crops. Hence, I still believe that technological advancements are still more important as these advancements can help crops grow for example, faster than normal crops, increasing food production.

In conclusion, I believe that technological advancements are the most important factor in increasing food production. Although i acknowledge that there are many other essential factors that contribute to increasing food production, technological advancements are after all the factor that boost the crop yield and food production.

Account for the trend of undernourishment between 1990 and 2005 in the respective country groups. [5]
The prevalence of undernourishment in the total population between 1990 and 2005 is decreasing in all three country groups. For Sub-Sahara Africa, South-East Asia and Central America the prevalence of undernourishment in total population decreased by 3%, 8% and 5% respectively from 1990 to 2005.( gd use of TAD) This is because there has been an increase in the disposable income in the country groups hence they would have more purchasing power to consume a larger amount and variety of food. Thus when they have more amount and variety of food to eat, they would not be undernourished as the variety of food gives them the nutrients that is needed and the increased amount food would fill their stomachs. Therefore, there has been an decrease in the prevalence of undernourishment between 1990 and 2005 in the three country groups.( perfect explanation with links to undernourishment but shld have 1 more reason)
