29% of Global GHG Emissions from Agriculture and Food Production

Feeding the world releases up to 17,000 megatonnes of carbon dioxide into the atmosphere annually, according to a new analysis released on 30 October  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.
While previous studies have looked at the contribution of agriculture to emissions, Climate Change and Food Systems assesses the entire food system's emissions "footprint" -- in total somewhere between a fifth and third of the greenhouse gases emitted by people on this planet. This figure accounts for every aspect of food production and distribution -- including growing crops and raising livestock, manufacturing fertilizer, and storing, transporting and refrigerating food. Agriculture accounts for around 80 percent of these emissions, but the combined contribution of transport, refrigeration, consumer practices and waste management is growing.
"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 in Doha," said Bruce Campbell, CCAFS's program director.
