This report contributes to the discussion of interconnections between scarce resources by highlighting the nexus between land, water and energy (the LWE nexus). It focuses on a dynamic, integrated, and disaggregated analysis of how land, water and energy interact in the biophysical and economic systems. The report provides projections for the biophysical and economic consequences of nexus bottlenecks until 2060, highlighting that while the LWE nexus is essentially local, there can be significant large-scale repercussions in vulnerable regions, notably on forest cover and in terms of food and water security. The analysis is based on coupling a gridded biophysical systems model with a multi-regional, multi-sectoral dynamic general equilibrium modelling assessment. Numerical insights are provided by investigating a carefully selected set of scenarios that are designed to illustrate the key bottlenecks: one scenario for each resource bottleneck, plus two scenarios that combine all bottlenecks, with and without an overlay of climate change.

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 existence of water, energy, and food (WEF) is critical for people to fulfil their basic needs, to achieve welfare, and to support the Sustainable Development Goals (SDGs). The WEF security topic is becoming widely discussed in developing and developed countries. Major components of WEF security i.e. availability, accessibility, and quality should be achieved integratedly to avoid unexpected impacts. The interconnectedness among endogenous and exogenous variables such as environmental, socio-economic, and political factors makes this issue immensely complex. The nexus approach attempts to integrate management and governance across sectors and scales to improve WEF security. This study aims to grasp WEF security in a local context and evaluate the implications of planned local interventions by developing a conceptual and quantitative analysis with local stakeholders. Karawang Regency in Indonesia is chosen as the case study. Several strategies for WEF-related sectors are formulated using location quotient (LQ) and competitive position (CP) methods. In addition, qualitative and quantitative system dynamics models are established by involving related stakeholders through group model building. Finally, a nexus-based framework for WEF security is developed to assist local policymakers in doing the evaluation and planning of WEF resources in the region.

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.

In a worldwide context of ever-growing competition for water and land, climate change, droughts and man-made water scarcity, and less-participatory water governance, agriculture faces the great challenge of producing enough food for a continually increasing population. In this line, this book provides a broad overview of innovation issues in the complex water–agriculture–food nexus, thus also relative to their interconnections and dependences. Issues refer to different spatial scales, from the field or the farm to the irrigation system or the river basin. Multidisciplinary approaches are used when analyzing the relationships between water, agriculture, and food security. The covered issues are quite diverse and include: innovation in crop evapotranspiration, crop coefficients and modeling; updates in research relative to crop water use and saving; irrigation scheduling and systems design; simulation models to support water and agricultural decisions; issues to cope with water scarcity and climate change; advances in water resource quality and sustainable uses; new tools for mapping and use of remote sensing information; and fostering a participative and inclusive governance of water for food security and population welfare. This book brings together a variety of contributions by leading international experts, professionals, and scholars in those diverse fields. It represents a major synthesis and state-of-the-art on various subjects, thus providing a valuable and updated resource for all researchers, professionals, policymakers, and post-graduate students interested in the complex world of the water–agriculture–food nexus.
