This chapter introduces a perspective that reconceptualises resource management: the interlinkages between the water–energy–food (WEF) nexus and the SDGs. This integrated framework serves as a tool for holistic thinking guided toward concerted SDG advancement.

The WEF nexus transcends traditional resource management, advocating for an integrative approach that considers the synergies and trade-offs between water, energy, and food systems. This chapter reflects on the evolution of the WEF nexus concept, exploring its potential to reshape our strategies for sustainable development. A core part of the discussion revolves around the intimate interlinkages between the WEF nexus and the broader SDGs. Through systematic mapping of the interlinkages between the WEF nexus and the SDGs, the authors provide an overall picture of the WEF-SDG system, highlighted by key SDGs and their linkages. To ground the discourse in reality, this chapter present a practical case examining the water–energy nexus within the Ganges River basin—a vital lifeline for millions.

Further, the authors enrich this chapter with illustrative examples from the research works of the Institute for Global Environmental Strategies (IGES) which demonstrate the tangible benefits of the WEF approach. These case studies exemplify how the integrated management of water, energy, and food resources can not only propel resource efficiency but also fortify other development imperatives.

The purpose of this chapter is not merely to inform but to equip policymakers, researchers, and practitioners with scientific evidence and practical insights. By showcasing the interlinkages of the WEF nexus with the SDGs and illustrating how this approach can act as a lever for integrated SDG advancement, the authors aim to provide a practical tool to guide actions toward a future where resources are managed with a deep sense of interconnectivity.
