River basin management is a holistic and integrated approach to the governance and management of water, land, and associated natural resources within the physical boundaries of a river basin. As a significant research field and methodological framework, it investigates the complex interactions between biophysical processes, human activities, and institutional arrangements, aiming to address challenges related to water quantity and quality, ecosystem health, and socio-economic development. Its key characteristics include interdisciplinarity, stakeholder engagement, and the coordination of policies and actions across sectors and jurisdictions to achieve sustainable and equitable resource use and conservation.
