The water–food–energy nexus is central to sustainable development. Demand for all three is increasing, driven by a rising global population, rapid urbanisation, changing diets and economic growth. In response, many countries are expanding irrigation infrastructure to produce food, and building dams to secure water and generate power. In some instances, this can create pressure for other food resources, such as fish. This Research Front explores the concept that irrigation and fisheries must advance collaboratively if the Sustainable Development Goals are to meet their intended goals of no poverty and zero hunger.
