Climate change and agriculture are interrelated processes, both of which take place on a global scale. Climate change 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 dioxideand ground-level ozone concentrations; changes in the nutritional quality of some foods;[1] and changes in sea level.[2]
Climate change is already affecting agriculture, with effects unevenly distributed across the world.[3] Future climate change will likely negatively affect crop production in low latitudecountries, while effects in northern latitudes may be positive or negative.[3]Climate change will probably increase the risk of food insecurity for some vulnerable groups, such as the poor.[4]Animal agriculture is also responsible for greenhouse gas production of CO2and a percentage of the world's methane, and future land infertility, and the displacement of local species.
Agriculture contributes to climate change both by anthropogenicemissions of greenhouse gases and by the conversion of non-agricultural land such as forests into agricultural land.[5]Agriculture, forestry and land-use change contributed around 20 to 25% to global annual emissions in 2010.[6]
