China's Sponge City Development: Global Position, Governance, and Potential Enhancement with Ecosystem Services

China has been implementing a policy initiative termed sponge city development (SCD) since 2014 to address complex, interlinked water challenges, particularly flooding and runoff pollution, faced by urban development under climate change. Pilot implementation of the initiative in 30 selected cities provides an opportunity for learning and enhancement relevant to global practice in general and SCD expansion in particular. This article reviews China's SCD, synthesizing: (1) SCD position in global practices for urban stormwater management; (2) governance and implementation; (3) challenges and issues in planning and management; and 4) potential enhancement with ecosystem service (ES). The article shares that: (1) China's SCD differs from, while sharing some similarity with, global practices for urban stormwater management, particularly marked by engineering dominated implementation; (2) the policy implementation exhibits sophisticated governance in supporting the initiative; (3) there are challenges and issues concerning particularly planning and management, characterized by a lack of a systematic approach linking physical projects, ecosystem functions, societal impact, and urban development goals; and (4) an ES-based framework can deliver a systematic approach enhancing SCD beyond water resilience toward urban green transition and sustainability. This article contributes to learning about ecosystem-based integrated stormwater management during urbanization and climate change.
