Climate change is no longer merely projected to occur in the indeterminate future. It has already begun to be manifested in the weather regimes affecting agroecosystems, food production, and rural livelihoods in many regions around the world. It is a real and growing challenge to the world at large and in particular to the scientific community, which is called upon with increasing urgency to respond effectively.The second volume in the ICP Series on Climate Change Impacts, Adaptation, and Mitigation, Handbook of Climate Change and Agroecosystems: Global and Regional Aspects and Implications is published jointly by the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America and Imperial College Press. The ongoing series is dedicated to elucidating the actual and potential impacts of climate change, and to formulating effective responses to this global challenge. It is designed to inform, spur, and integrate the work of leading researchers in the major regions of the world, and to further international cooperation in this crucial field.Contents:Introduction:Climate Change and Agroecosystems: Global and Regional Perspectives (Daniel Hillel and Cynthia Rosenzweig)Themes:Agriculture and Environment in a Crowding and Warming World (Daniel Hillel and Cynthia Rosenzweig)Contributions to Climate Change Solutions from the Agronomy Perspective (David W Wolfe)Regions:North American Perspectives on Potential Climate Change and Agricultural Responses (Jerry L Hatfield)Latin American Perspectives on Adaptation of Agricultural Systems to Climate Variability and Change (Walter E Baethgen and Lisa Goddard)European Perspectives: An Agronomic Science Plan for Food Security in a Changing Climate (John R Porter, Jean-Francois Soussana, Elias Fereres, Stephen Long, Fritz Mohren, Pirjo Peltonen-Sainio and Joachim von Braun)African Perspectives on Climate Change and Agriculture: Impacts, Adaptation, and Mitigation Potential (Jesse Naab, Andre Bationo, Benson M Wafula, Pierre S Traore, Robert Zougmore, Mamadou Ouattara, Ramadjita Tabo and Paul L G Vlek)Australia and New Zealand Perspectives on Climate Change and Agriculture (Peter J Thorburn, Michael J Robertson, Brent E Clothier, Val O Snow, Ed Charmley, Jon Sanderman, Edmar Teixeira, Robyn A Dynes, Alistair Hall, Hamish Brown, S Mark Howden and Michael Battaglia)Middle East and North Africa Perspectives on Climate Change and Agriculture: Adaptation Strategies (Shawki Barghouti, Shoaib Ismail and Rachael Monnell)Israeli Perspectives on Climate Change Influences on Semi-Arid Agriculture, Forestry, and Soil Conservation (Shabtai Cohen, Guy Levy and Meni Ben-Hur)China Perspectives on Climate Change and Agriculture: Impacts, Adaptation and Mitigation Potential (Liang Tang, Yan Zhu, Weixing Cao and Yu Zhang)South Asia Perspectives on Climate Change and Agriculture: Adaptation Options (Pramod Aggarwal, Himanshu Pathak, Soora N Kumar and Pradeep Sharma)Programs and Projects:Research Needs for Agriculture Under Elevated Carbon Dioxide (Mary Beth Kirkham)Contributions of WMO Programs in Addressing Climate Change and Agriculture (Mannava V K Sivakumar, Oksana Tarasova, Slobodan Nickovic, Deon Terblanche and Ghassem Asrar)The Agricultural Model Intercomparison and Improvement Project (AgMIP): Integrated Regional Assessment Projects (Cynthia Rosenzweig, James W Jones, Jerry L Hatfield, Carolyn Z Mutter, Samuel G K Adiku, Ashfaq Ahmed, Yacob Beletse, Babooji Gangwar, Dileepkumar Guntuku, Job Kihara, Patricia Masikati, Ponnusamy Paramasivan, K P C Rao and Lareef Zubair)Conclusion: Agricultural Solutions for Climate Change at Global and Regional Scales (Cynthia Rosenzweig and Daniel Hillel)Readership: Advanced undergraduates and graduate students, academia and researchers in climate change, agricultural sciences and biology.
