Climate change impacts on water resources through changes in precipitation, snowfall, soil moisture, river flow and groundwater recharge. With agriculture the largest global water consumer, it is easy to see that the effects of climate change on agricultural production will be both significant and wide-ranging. This book provides an analysis of climate change impacts on water for agriculture, and the adaptation strategies needed to deal with these impacts. Adaptation measures including groundwater management, water storage and irrigation are presented, with chapters including assessment at global level and on impacts in specific countries. Covering the implications of sea level rise for agriculture, it also considers the social vulnerability to climate change among farmers at different scales, the linking of climate change with policy, and the results of water management on greenhouse gas emissions as an effort towards climate change mitigation. Using case studies from developing countries, this book provides a vital and up-to-date resource for agriculture and irrigation researchers and policy makers.
