The dominance of insular, supply-side technocratic thinking has posed a major challenge to improving water governance in the face of mounting resource scarcity, which has itself been accentuated by climate change. During the 1990s, global discourse moved from supply-driven sectoral interventions to more holistic approaches to water governance as part of larger socioeconomic and environmental processes. Integrated water resources management (IWRM) emphasized demand-side water management and used prices, participation, entitlements, laws and regulations to strengthen water governance at hydrological rather than territorial units. More recently, there have been pleas for more integrative approaches that link land, water, energy, food, livelihoods, the environment and other spheres – each with its own, often insular, governance structure. The evolution in global thinking reflects the need to meet growing human needs by innovating approaches that enhance resilience and the sustainability of landscapes, the biosphere and the Earth as a whole. To this end, the water–energy–food (WEF) nexus advocates that society is better off seeking system-level balance rather than maximizing sectoral objectives. The nexus approach has produced prolific analytical literature over the past decade but integrating it into policy and governance faces many challenges. This review paper explores these challenges by focusing on the WEF nexus in action. We compare the nexus in several water-stressed areas of the world including Iran, Saudi Arabia, Mexico, China, Bangladesh and Gujarat (India), with additional evidence drawn from other places such as Morocco and Punjab-Haryana. We synthesize these case studies to examine the actual state of play in different locations and tease out practical lessons for mainstreaming nexus thinking in water policy and governance. The key conclusion is that specific contexts, contingencies and constituencies drive national and sub-national policies. Directing the outcomes towards the optimal nexus depends on the nature of the state, investment in institution building and, above all, ingenuity in policy design and implementation to overcome resistance to change and strengthen political capital for the leaders who back such policies.

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.

Satisfying the changing food habits and increased demand for food intensifies pressure on the world’s water, land and soil resources. However, agriculture bears great promise to alleviate these pressures and provide multiple opportunities to contribute to global goals. Sustainable agricultural practices lead to water saving, soil conservation, sustainable land management, conservation of natural resources, ecosystem and climate change benefits. Accomplishing this requires accurate information and a major change in how we manage these resources. It also requires complementing efforts from outside the natural resources management domain to maximize synergies and manage trade-offs. The objective of SOLAW 2021 is to build awareness of the status of land and water resources, highlighting the risks, and informing on related opportunities and challenges, also underlining the essential contribution of appropriate policies, institutions and investments. Recent assessments, projections and scenarios from the international community show the continued and increasing depletion of land and water resources, loss of biodiversity, associated degradation and pollution, and scarcity in the primary natural resources. SOLAW 2021 highlights the major risks and trends related to land and water and presents means of resolving competition among users and generating multiple benefits for people and the environment. The DPSIR framework was followed in order to identify the Drivers, Pressures, Status, Impact and Responses. SOLAW 2021 provides an update of the knowledge base and presents a suite of responses and actions to inform decision-makers in the public, private, and civil sectors for a transformation from degradation and vulnerability toward sustainability and resilience.

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 becoming increasingly recognized that for the optimal sustainable development and use of natural resources, an integrated approach to water management, agriculture, food security and energy is required. This "nexus" is now the focus of major attention by researchers, policy-makers and practitioners. In this book, the authors show how these issues are being addressed in India as part of its economic development, and how these can provide lessons for other developing nations. They address the conflicting claims of water resources for irrigation and hydropower, where both are scarce at the national level for fostering water and energy security. They also consider the relationship between water for irrigated agriculture and household use and its impact on rural poverty. They identify weaknesses in the current hydropower development programme in India that are preventing it from being an ecologically sustainable, socially just and economically viable solution to meeting growing energy demand. The empirical analyses presented show the enormous scope for co-management of water, energy, agricultural growth and food security through appropriate technological interventions and market instruments.

The WWDR 2014 on Water and Energy is now an annual and thematic report with a focus on different strategic water issues each year. It is shorter in the order of 100 pages with a standardized structure and data and case studies annexes related to the theme. The WWDR 2014 will be launched during the main World Water Day celebrations in Tokyo, Japan on 21 March 2014. Water and energy are closely interconnected and highly interdependent. Trade-offs need to be managed to limit negative impacts and foster opportunities for synergy. Water and energy have crucial impacts on poverty alleviation both directly, as a number of the Millennium Development Goals depend on major improvements in access to water, sanitation, power and energy sources, and indirectly, as water and energy can be binding constraints on economic growth the ultimate hope for widespread poverty reduction. This fifth edition of the United Nations World Water Development Report (WWDR 2014) seeks to inform decision-makers

This book contributes to the on-going debates on climate change by focusing on the SDGs and exploring linkages between environmental change and food security as well as the relevance and need to consider the management of natural resources, especially water, soil and forest. Compared to relevant existing publications, this book covers case studies that capture the everyday realities of the local people and how they react and adapt to similar situations in different geographical settings. Each case study presented in this book gives a particular message. The strength of this book lies in the fact that it covers the most neglected topics in climate negotiations in spite of the fact that these decide the fate of millions of people around the world, especially the developing countries. By presenting a collection of case studies from Africa, Asia and Europe, this book encourages cross-continental knowledge sharing. The scope of the book ranges from impacts to mitigation and from in-field experiments to policy implementation. It contributes to the existing knowledge on climate-food nexus and connects climate change to sectors it could impact directly. All chapters in this book emphasise local ownership of strategy processes, effective participation from all levels, and high-level commitment. Besides being relevant for the academicians and scholars working in the field of climate change, forest and agriculture, it aims to catch interest of the policy makers and practitioners to understand ground realities for appropriate action. It is also bound to make an impact on the Non-Governmental Organizations around the world and in the three different continents that this book covers, considering the indigenous and local issues highlighted in this book.
