Farming: Climate change
Multiple sources of emissionsAgricultural practices are responsible for around 14% of global greenhouse gas emissions1. Sources include fertilizers, livestock, wetland rice cultivation, manure management, burning of savanna and agricultural residues, and ploughing.
For example, rice production is one of the single-largest producers of methane, while the UN Food and Agriculture Organization (FAO) recently stated that the livestock sector alone is responsible for 18% of all greenhouse gas production.
In addition, the conversion of forests to agriculture – particularly in tropical Asia – accounts for a roughly similar percentage of greenhouse gas emissions as agriculture itself2.
