Planning for food security in a changing climate

摘要: The Intergovernmental Panel on Climate Change and other international agencies have concluded that global crop production is at risk due to climate change, population growth, changing food preferences. Society expects the agricultural sciences will innovate solutions these problems provide security for foreseeable future. My thesis an integrated research plan merging agronomic genetic approaches has greatest probability of success. I present a template based lessons we learned from Green Revolution development genetically engineered crops may guide us meet this expectation. starts with vision how management system could give few examples innovations are very much in their infancy but significant potential. opportunities need be conceptualized regional basis each target change. gives overview tools plant biotechnology can used create diversity needed implement envisioned changes system, using drought tolerance maize (Zea mays L.) as example led recently commercial release new hybrids USA. requires interdisciplinary approach integrates coordinates biotechnology, genetics, physiology, breeding, agronomy, cropping systems successful.
