  • Abstract:
  • Climate change, rapid urbanization, and inadequate urban planning strategies have led to significant urban water challenges, including severe flooding, water pollution, and water scarcity. To address these pressing issues, a novel urban water management approach, the sponge city concept, has emerged. This complex approach, however, presents numerous challenges. This paper critically evaluates traditional urban water management practices. Subsequently, the sponge city concept and its implementation are examined to comprehensively assess its potential and limitations. The sponge city concept is underpinned by four primary principles: sustainable urban water sourcing, ecological water management, green infrastructure, and permeable urban surfaces. However, uncertainties inherent in sponge city design and planning, coupled with financial constraints, pose significant risks to its successful implementation. Despite significant challenges, there are clear opportunities to implement sponge city strategies. To maximize the multiple ecosystem services offered by sponge cities, implementation should be undertaken at watershed scales and remain adaptable to varying decision-making levels and catchment characteristics. A robust decision-making framework is essential, along with strong inter-agency collaboration, with the central government playing a pivotal coordinating role. An appropriately scaled and harmonious sponge city, balancing socioeconomic development with environmental sustainability, represents the ideal outcome.
