Change in agricultural production in the

This solution is beneficial in its overall environmental impact.


Increases in atmospheric CO2 can increase the productivity of plants on which livestock feed. On the other hand, agricultural trade has grown in recent years, and now provides significant amounts of food, on a national level to major importing countries, as well as comfortable income to exporting ones.

There is some evidence that climate change is already having a measurable affect on the quality and quantity of food produced globally. For example, the complex interlinkages with the impacts of climate change on pests, diseases and pollinators, like bees, are largely unknown.

Access has been affected by the thousands of crops being destroyed, how communities are dealing with climate shocks and adapting to climate change. Sheep were domesticated in Mesopotamia between 13, and 11, years ago.

Sorghum was domesticated in the Sahel region of Africa by 7, years ago. Food Safety, Nutrition, and Distribution. This could increase the risk of pesticides entering the food chain or lead to evolution of pesticide resistance, with subsequent implications for the safety, distribution, and consumption of livestock and aquaculture products.

In developing countries, adaptation options like changes in crop-management or ranching practices, or improvements to irrigation are more limited than in the United States and other industrialized nations.

This type of farming is practiced mainly in highly developed countries. A Foresight report concluded that climate change is a relatively small factor here, at least in the short term, when compared with the rapid increases in global food demand expected in the next decade.


In the IPCC Fourth Assessment Report, "low confidence" means that a particular finding has about a 2 out of 10 chance of being correct, based on expert judgement. This has been achieved primarily with a technological revolution that has increased yields through increases in modern inputs—irrigation, improved seeds, fertilizer, tractors and pesticides figure 2.

As a result, cattle would need to eat more to get the same nutritional benefits. Some laboratory experiments suggest that elevated CO2 levels can increase plant growth. Impacts to the global food supply concern the United States because food shortages can cause humanitarian crises and national security concerns.

Introduction Agriculture is strongly influenced by weather and climate. Along with a few technological breakthroughs to increase yields, the food needs of growing populations were historically met by expanding the cultivated area.

This paper focuses on impacts on crop productivity, but many of the processes and impacts discussed may also apply to livestock. While the Government Office for Science commissioned this review, the views are those of the author sare independent of Government, and do not constitute Government policy.

Dark purple indicates areas where double cropping has been abandoned. Not only are more native plants getting planted, but pest insects are no longer building up an immunity to pesticides.As a result of climate change, many regions that already suffer from high rates of hunger and food insecurity are predicted to experience the greatest declines in food production.

7–9 In drought-stricken regions like Kenya (pictured), many cattle farmers have already lost their animals, their livelihoods, and their sources of food and income.

Climatic variability and change directly affect agricultural production and food security given that most of the population in Kenya lives in the rural areas and relies on agriculture for its livelihoods. GTAP Resource # "Climate Change, Agricultural Production and Trade in Africa" by Balcha, Yodit and Jamie Macleod Abstract According to IPCC () predictions climate change is forecast to hit Africa heavily, with temperatures rising on the continent more than the global median, extreme weather events becoming more prevalent, and drier areas becoming even drier.

Nov 15,  · Agriculture has a potential role to play in the removal of carbon dioxide from the atmosphere.

Climate Impacts on Agriculture and Food Supply

Land managers can change production practices or land uses to increase the carbon stored in soil or vegetation. Land managers can use other changes in production practices and land uses to reduce emissions of methane and nitrous oxide.

In addition, agriculture can produce biofuels, which. Effects of climate variability and change on agricultural production: The case of small scale farmers in Kenya. How will climate change affect food production?

Agricultural Production and Mitigation

and so it is impossible to know how our agricultural systems will react in the real world. For example, the complex interlinkages with the.
