Agriculture is in a difficult position as far as climate change goes. Cows release huge amounts of warming methane (a potent greenhouse gas) every year. The Intergovernmental Panel on Climate Change estimates agricultural emissions account for 13.5 percent of all manmade greenhouse gas emissions. At the same time, poor countries want more money and better technology to help farmers adapt to the impact of climate change such as frequent droughts, flooding and increased salinity. "It is really a bad split for agriculture," said John Beddington, who was until recently the UK's chief scientific adviser, and one of the authors of a paper calling for a more integrated approach, combining mitigation and adaptation efforts. The paper, published in the Journal 'Science' with contributions from several scientists, called for a better understanding of agricultural practices with the aim of delivering multiple benefits - reducing emissions, helping agriculture to adapt, and using limited resources (like water) efficiently
