A water-function-based framework for understanding and governing water resilience in the Anthropocene
One Earth(2021)
摘要
The freshwater cycle over land is fundamental for sustainability and resilience, yet is extensively modified and shaped by a vast range of human interventions in the land, water, and climate systems. The consequences of human water-cycle modifications can be non-linear, delayed, and distributed across boundaries, sectors, and scale. This complexity renders freshwater challenges difficult to govern and manage. We here propose a framework for understanding water's many functions for supporting, regulating, and stabilizing hydro-climatic, hydro-ecological, and hydro-social systems. This framework recognizes human impacts on major partitioning points, interactions among water functions, and stabilization and destabilization processes. A functional understanding of the freshwater cycle can integrate with social-ecological resilience-building principles, complement existing water sustainability governance approaches, and highlight the potential need for Earth-system-level governance of water. Recognizing water's diverse functional roles for resilience may promote a new generation of holistic and integrative water-land-climate governance.
