Climate Change and Global Food Security - Section 5

Cuộc tranh luận về sự nóng lên toàn cầu có xu hướng được khá cường độ cao. Các đóng góp cho khối lượng này, tuy nhiên, vượt ra ngoài các cuộc tranh luận khá bực bội về nguyên nhân của sự nóng lên toàn cầu, và đã tìm cách thay vì để cải thiện của chúng tôi sự hiểu biết về các vấn đề như hậu quả của bất kỳ sự ấm lên cho năng suất nông nghiệp và trên mặt đất, đóng góp tiềm năng hấp thụ các-bon để giảm sự nóng lên toàn cầu, và những ảnh hưởng của những nỗ lực giảm nhẹ dự. | Section V Policy and Economic Issues 2005 by Taylor Francis Group LLC 26 Policy and Economic Issues Dealing with Global Warming G.

The contributions to this volume have however moved beyond the rather frustrating debates about causes of global warming and have sought instead to improve our understanding of such issues as the consequences of any warming for agricultural and terrestrial productivity the potential contributions of carbon sequestration to reducing global warming and the effects of mitigation efforts expected at the farm level. We are offered a cornucopia of scientific analyses and evidence on these issues together with some constructive debate. It is important to address the policy and economic dimensions of this subject. Both aspects have received too little attention in the discussions of global warming. It is true that some of the economic costs and implications have received attention in recent years see e.g. Nordhaus 1994 but economic policy issues have still received only limited attention. Technological solutions to the problem have also received some attention as evidenced in the contributions to this volume but even then the range of alternatives considered has been rather limited. This chapter has three main focuses 1 .
