Empirical studies that examined the potential of polycentric governance to address water challenges in the face of climate change showed that polycentrism could encourage and support participatory, decentralised and deliberative adaptation. These, in turn, can produce better environmental outcomes and improve water governance outcomes . Polycentric water governance can be an effective enabler for adaptation when it ensures interconnectedness with multiple public and private actors across the different sectors  and across different levels  to help come up with well-coordinated water adaptation responses  .
