effects of agriculture on global warming
Answers
Answer:
Climate change and agriculture are interrelated processes, both of which take place on a global scale. Global warming affects agriculture in a number of ways, including through changes in average temperatures, rainfall, and climate extremes (e.g., heat waves); changes in pests and diseases; changes in atmospheric carbon dioxide and ground-level ozone concentrations; changes in the nutritional quality of some foods;[2] and changes in sea level.[3]
Climate change is already affecting agriculture, with effects unevenly distributed across the world.[4] Future climate change will likely negatively affect crop production in low latitude countries, while effects in northern latitudes may be positive or negative.[4] Animal agriculture is also responsible for CO
2 greenhouse gas production and a percentage of the world's methane, and future land infertility, and the displacement of local species.
Agriculture contributes to climate change both by anthropogenic emissions of greenhouse gases and by the conversion of non-agricultural land such as forests into agricultural land.[5] In 2010, agriculture, forestry and land-use change were estimated to contribute 20–25% of global annual emissions.[6]. In 2020, the European Union's Scientific Advice Mechanism estimated that the food system as a whole contributed 37% of total greenhouse gas emissions, and that this figure was on course to increase by 30–40% by 2050 due to population growth and dietary change.[7]
A range of policies can reduce the risk of negative climate change impacts on agriculture[8][9] and greenhouse gas emissions from the agriculture sector.[10][11][12]
