Agriculture may contribute 29% to global greenhouse gas emissions

Feeding the world releases up to 17,000 megatonnes of carbon dioxide into the atmosphere annually, a new analysis has revealed.

According to the report by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), while the emissions "footprint" of food production needs to be reduced, a companion policy brief by CCAFS lays out how climate change will require a complete recalibration of where specific crops are grown and livestock are raised.
