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.
位于沿海的城市中心使一些最脆弱的人群暴露于气候变化的影响之下。除了面临人口高密度和相互依存的社会生态系统所带来的挑战外，对资源的需求也在不断增加。暴露那些已经对极端天气敏感的关键点，凸显了面对气候变化时最缺乏复原力的城市系统。我们在几个空间尺度上，将预计的水资源可利用量变化映射到食物-水-能源关系的各个组成部分上。复原力思维承认治理运作、复原力产生以及关系系统发挥作用的不同空间尺度。我们通过一个案例研究来说明，远离城市地区的气候变化影响如何通过关系的级联效应以多种方式影响城市社区的复原力。本文强调了从多个空间和治理角度审视复原力的必要性。
