This book discusses an emerging context of climate change, environmental degradation, monitoring and management, agricultural vulnerability and its development and adaptation from local to global scale. The book also describes the research methodology in a simple and lucid way so that a researcher can adopt it in his/her field studies. Individual chapters are dedicated to different subjects such as the quantification of climate change impacts on environment; land use land cover; crops in controlled and field conditions; water resources; soil fertility, erosion and carbon sequestration; insects, pests, weeds, microbes and diseases; greenhouse gas emission assessment; regional vulnerability to climate change; and selection of crop. Researchers from around the world and from various fields explore these important topics in the book. The book is a valuable resource for environmentalists, geographers, economists, agronomists, biologists, agricultural scientist, climate modellers, policyanalysts, development agency staff, and graduate and postgraduate students.
