Agriculture and food production contribute up to 29 percent of global greenhouse gas emissions

Feeding the world releases up to 17,000 megatonnes of carbon dioxide into the atmosphere annually, according to a new analysis released October 30 by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS). But 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.

Together, Climate Change and Food Systems (published in the 2012 Annual Review of Environment and Resources) and Recalibrating Food Production in the Developing World: Global Warming Will Change More Than Just the Climate (published by CCAFS), shed new light on the intertwining evolutions of climate change and the world's food system and their potential impact on humanity's relationship with food.

"Climate Change mitigation and adaptation are critical priorities. Farmers around the world, especially smallholder farmers in developing countries, need access to the latest science, more resources and advanced technology. This research serves as an urgent call for negotiators at the upcoming United Nations Framework Convention on Climate Change (UNFCCC) in Doha," said Bruce Campbell, CCAFS's program director.
