Climate-smart agriculture is a practice that helps to guide activities needed to transform and reorient agricultural systems to effectively support development and ensure food security in a changing climate. It aims to sustainably increase agricultural productivity and incomes, reducing greenhouse gas emissions, and adapt and build resilience to climate change. Climate-smart agriculture supplies the means to help economic agents from local to national and international levels identify agricultural strategies suitable to their local conditions. Landscape approach is adopted by climate smart agriculture which builds upon the principles of sustainable agriculture but goes beyond the narrow sectoral approaches, resulting in uncoordinated and competing land uses in order to integrate planning and management. This book discusses the fundamentals as well as modern approaches to climate-smart agriculture. While understanding the long-term perspectives of the topics, it makes an effort in highlighting their impact as a modern tool for the growth of the discipline.
