Examining urban resilience through a food-water-energy nexus lens to understand the effects of climate change

Urban centers located on the coast expose some of the most vulnerable populations to the effects of climate change. In addition to the challenges faced by high population densities and interdependent social-ecological systems, there is an increasing demand for resources. Exposing the pinch points that are already sensitive to extreme weather, highlights the urban systems that will be least resilient in the face of climate change. We map the projected changes in water availability onto the components of the food-water-energy Nexus at several spatial scales. Resilience thinking acknowledges the different spatial scales at which governance operates, resilience occurs, and Nexus systems function. We use a case study to illustrate how the effects of climate change at locations remote from the city could impact resilience of urban communities in multiple ways through cascading effects from the Nexus. This article underscores the need to examine resilience from multiple spatial and governance angles.
