This book addresses the technologies that can be employed to tackle the challenges of global food security. Several recent studies have reported the significant impact of changing climate on the agricultural production, thus posing a challenge in achieving global food security. Thus, to mitigate these challenges there is an urgent need to develop approaches that may be helpful for the sustainability of food production. These approaches are based on three objectives: (i) sustainably increasing agricultural productivity to support equitable increases in farm incomes, food security, and development; (ii) adapting and building the resilience of food systems to climate change; and (iii), where possible, reducing GHGs emissions from agriculture. This book provides updated information for these climate-smart agricultural technologies that hold high potential to increase productivity, improve resilience, and provide efficient resource utilization. This book is a valuable resource for undergraduates, postgraduates, researchers, professors and policymakers in the field of agriculture, botany and agriculture extension functionaries.
