ABSTRACT: Across the world, humans are increasingly moving from the countryside to cities. This resultant rapid urbanization concentrates the demand of freshwater ecosystem services. In particular, the increased urban population demands more services from not only surrounding watersheds but also distant watersheds through the construction of infrastructure (e.g., dams). However, maintaining benefits to humans with built infrastructure while conserving healthy freshwater ecosystems is a complex challenge. A new strategy is needed to combine built infrastructure with natural infrastructure (e.g., wetland restoration). This study examines the roles of built and natural infrastructure in source watersheds for freshwater supply to urban areas using the ego-centric network analysis. Our results indicate that natural infrastructure plays an important role in sustaining freshwater supply to urban areas while built infrastructure focuses on freshwater supply in source watersheds. The results will have important implications for global urban sustainability in the telecoupled Anthropocene.
