Cities are becoming increasingly more populated and rapid urbanization is taking place all around the world. This requires larger supplies of input and output resources to sustain human and urban needs. Water, Energy and Food (WEF) have long been acknowledged as essential inputs to feed cities. Urban planners have, however, often treated water, energy and food as separate domains. What is missing is an ‘Urban Nexus’ perspective which assumes that Environmental Flows of WEF interact and relate to one another in achieving urban sustainable development. This research seeks to contribute to theorize, analyze, identify and visualize this Urban Nexus, which thus far remains quite obscure and complex to policy-planners, producers and consumers. It will offer an analytical framework to study the Urban Nexus of Water, Energy and Food resources through a material and non-material Environmental Flow Analysis. The material analysis will examine and show the processes and flows in which WEF systems go through: (1) resources inputs, (2) infrastructures, and (3) services provided. Thereafter, the non-material analysis will focus on how (1) actors, (2) social dynamics, (3) and institutional arrangements come together in the scene of WEF nexus. Finally this research aims to use novel visualization techniques to spotlight the Nexus findings of these flows in a conceptual flows diagram.
