Circular Water Economy in River Basin Management

Abstract

Increasing water scarcity, climate variability, population growth, and ecosystem degradation have exposed the limitations of linear water management approaches that focus on extraction, use, and disposal. River basins, as natural hydrological units, demand integrated and sustainable strategies to balance human and ecological water needs. The concept of a circular water economy offers a transformative framework that emphasizes water reuse, recycling, recovery of resources, and minimization of waste within river basin systems. This paper explores the principles of the circular water economy and its application to river basin management. It discusses conceptual foundations, enabling technologies, governance mechanisms, environmental and socioeconomic benefits, implementation challenges, and future directions. By integrating circular economy principles with basin-scale planning, river basin management can evolve toward long-term water security, ecosystem resilience, and sustainable development.
