This will be the first textbook on the integration of food, energy and water systems (FEWS). In recent years, the world has seen a dramatic rise in interdisciplinary energy and environmental courses and degrees at the undergraduate and graduate levels. In the US for instance, the number and variety of such programs has increased significantly over the past decade, Simultaneously, national and international initiatives that integrate food, energy and water systems have been launched. This textbook provides a substantive introduction to the food-energy-water nexus suitable for use in higher level undergraduate and graduate level courses and for scholars moving into the field of nexus studies without a strong background in all three areas and the many aspects of nexus studies.

Global trends of population growth, rising living standards and the rapidly increasing urbanized world are increasing the demand on water, food and energy. Added to this is the growing threat of climate change which will have huge impacts on water and food availability. It is increasingly clear that there is no place in an interlinked world for isolated solutions aimed at just one sector. In recent years the "nexus" has emerged as a powerful concept to capture these inter-linkages of resources and is now a key feature of policy-making. This book is one of the first to provide a broad overview of both the science behind the nexus and the implications for policies and sustainable development. It brings together contributions by leading intergovernmental and governmental officials, industry, scientists and other stakeholder thinkers who are working to develop the approaches to the Nexus of water-food-energy and climate. It represents a major synthesis and state-of-the-art assessment of the Nexus by major players, in light of the adoption by the United Nations of the new Sustainable Development Goals and Targets in 2015.

Water, Energy and Food are the very basic necessities of human life and all the three of them are interconnected with each other, this connection being called the Water-Energy-Food nexus. Water is an inevitable element to energy and food systems to work. Water is essential for the growth of crops and produce energy and it consumes a lot of energy to treat and move water. Food and energy are equally dependent upon each other as well. This book highlights with various examples and case studies from around the World, the importance of this concept.

It is beyond doubt that the interconnectedness between food, energy, water security and environmental sustainability exists and is getting amplified with increased globalization. It has been recognized that efforts to address only one part of a systemic problem by neglecting other inherently interlinked aspects may not lead to desirable and sustainable outcomes. In this perspective, policy- and decision- making requires a nexus approach that reduces trade-offs and builds synergies across sectors, and helps to reduce costs and increase benefits for humans and nature compared to independent approaches to the management of water, energy, food and the environment. In the past, work related to the Nexus has looked at the interactions between water and food or water and energy, but there has been a reluctance to bring forward a broader systematic perspective that captures the multiple sectors and resource dependencies while understanding its cost to the environment if we neglect these linkages. This book is a compilation of thirteen papers published previously as a special issue of Water International, contains significant pieces of work on the W-E-F nexus focusing on relevant tools, solutions and governance at local and broader human scales.

The book’s primary intention is to serve as a roadmap for professionals working in developing countries interested in the Nexus Water-Energy-Food-Ecosystems (WEFE) approach. The book shows a multi-disciplinary approach, showcasing the importance of the proper use of Nexus WEFE when implementing certain development programs in regions around the globe. It can be presented as a manual for an individual that either wishes to implement intervention projects following the NEXUS approach or students interested in cooperation and development. The book begins with a general explanation of the theoretical concepts and implementation processes of Nexus WEFE and continues getting into case studies, explaining the importance of proper implementation and potential drawbacks and solutions to them. This book has a particular focus on the European Union cooperation policies when implementing such an approach in developing countries.

This collection critically engages the resource use nexus. Clearly, a nexus-approach to resource policy, planning and practice is essential if sustainable development goals are to be met. In particular, in an era of climate change, an integrated approach to water, energy and agriculture is imperative. Agriculture accounts for 70% of global water withdrawals, food production accounts for 30% of global energy use and a rising global population requires more of everything. As shown in this collection, scholars of resource development, governance and management are ‘nexus sensitive’, utilizing a sort of ‘nexus sensibility’ in their work as it focuses on the needs of people particularly, but not only, in the global South. Importantly, a nexus-approach presents academics and practitioners with a discursive space in which to shape policy through research, to deepen and improve understandings of the interconnections and impacts of particular types of resource use, and to critically reflect on actions taken in the name of the ‘nexus’.

HANDBOOK OF CATCHMENT MANAGEMENT In 2010, the first edition of the Handbook of Catchment Management provided a benchmark on how our understanding and actions in water management within a catchment context had evolved in recent decades. Over ten years on, the catchment management concept is entering a new phase of development aligned to contemporary and future challenges. These include climate change uncertainty, further understanding in ecological functioning under change, the drive for a low-carbon, energy efficient and circular society, multiple uses of water, the emergence of new pollutants of concern, new approaches to valuation, finance and pricing mechanisms, stewardship and community engagement, the integration of water across the Sustainable Development Goals (SDG) and the link between water, energy and food. These developments are framed within an increasingly data rich world where new analytics, sensor technology and processing power are informing increasingly real-time decision making. The challenge is also to increase cross-compliance and policy integration to meet multiple stakeholder objectives, and to link actions to achieve cost-effective outcomes. In addition, there are a number of new and exciting city, region and basin-scale real-world examples of contemporary and new catchment thinking; integrating science, technology, knowledge and governance to address multiple drivers and complex problems from across the globe. The time is now right, to capture the new challenges facing catchment management and water resources management globally. This revised and updated edition of the Handbook of Catchment Management features: Thoroughly rewritten chapters which provide an up-to-date view of catchment management issues and contexts New case study material highlighting multi-sectoral management in different globally significant basins and different geographical locations Up-to-date topics selected for their resonance not only in natural sciences and engineering, but also in other fields, such as socio-economics, law and policy The Handbook is designed for a broad audience, but will be particularly useful for advanced students, researchers, academics and water sector professionals such as planners, consultants and regulators.
