Irrigated agriculture accounts for around 70% of global water use. However, an estimated 60% of irrigated cropland remains highly water-stressed, a problem intensified by the effects of climate change. Improving water management in agriculture considers ways of addressing this challenge. It reviews advances in monitoring and optimizing irrigation efficiency, ways of retaining and re-using water resources as well as how farmers can work collaboratively with other stakeholders to manage watersheds more sustainably. The book highlights key areas where innovation is required to ensure that water use is optimised at farm and watershed scales. The book encourages farmers to reassess their current irrigation models and implement alternative practices which improve efficiency with a reduced environmental impact.

Water-Energy-Food Nexus Narratives and Resource Securities: A Global South Perspective provides a knowledge synthesis on the water-energy-food (WEF) nexus, focusing primarily on the global south. By presenting concepts, analytical tools, and case studies, the book serves as a practical resource for researchers, policymakers, and practitioners in sustainability and functional roles across all three sectors. It addresses key issues related to data availability, tools, indices, metrics, and application across multiple scales, beginning with a summary of existing knowledge. Finally, it examines the WEF nexus, presents global insights, and discusses future considerations and implications. This book presents an overview of existing knowledge on the WEF nexus and examines how such research aligns with emerging global WEF nexus perspectives, making it ideal for professionals, government entities, private industry, and the general public.
