Summit urged to clean up farming : Nature News & Comment
international progress on tackling climate change need to look beyond smoke stacks and car exhausts to a neglected source of emissions — agriculture.
That's the message from an international group of leading agricultural and climate scientists in a report published on 16 November. They say that agriculture is the “single largest contributor to greenhouse-gas pollution on the planet”, through routes such as deforestation, rice growing and animal husbandry (see 'Farming footprint'). Emissions include nitrous oxide from fertilizer and methane from livestock, as well as carbon dioxide. With global food demand projected to double by 2050, agriculture's emissions will grow — unless farming can become dramatically more efficient. Agriculture is a “poor relation” in negotiations on strategies to mitigate climate change, says John Beddington, Britain's chief scientific adviser and chair of the Commission on Sustainable Agriculture and Climate Change, an initiative of the Consultative Group on International Agricultural Research in Washington DC, which produced the report.
...Benton believes that the “intellectual weight” of the report's authors will help it to influence policy-makers. As well as Beddington and Mamo, they include Carlos Nobre, a climate scientist at Brazil's National Institute for Space Research in São Paulo, and Marion Guillou, president of the French National Institute for Agriculture in Paris.
