Deployment of decentralised water management through effective local governance frameworks, is an important water management strategy , but in general, insufficient institutional learning and capacity remains a critical barrier for the uptake of sustainable urban water management practices . Transnational networks of cities for sharing best practices in water supply and storm runoff treatment also hold the potential to scale sustainable management . In rapidly growing large urban areas, sustainable water management faces challenges of institutional heterogeneity , scalar mismatch, particularly between river basin and city scales , and equity and justice concerns . Finally, assessing the vulnerability of urban water infrastructures at city scale remains an important knowledge gap .
