Global climate change is one of the most serious threats to the environment of the earth and to the crop production. Crop’s vulnerability to climate change stress caused by the greenhouse gases emission is a serious concern. This book describes various technologies and methods including the simulation of the future climate changes, studying the response of crop plants and characterizing their responses physiologically and biochemically. It includes the latest information of protocols and technologies for climate change research on agriculture. This book is of interest to teachers, researchers, climate change scientists, capacity builders and policymakers. Also the book serves as additional reading material for undergraduate and graduate students of agriculture, forestry, ecology, soil science, and environmental sciences. National and international agricultural scientists, policy makers will also find this to be a useful read.
