According to The Nature Conservancy, integrated river basin management (IRBM) is the collaborative process of integrating the conservation, management, and development of water, land, and related resources across sectors within a given river basin. The purpose is to improve economic and social benefits derived from water resources in an equitable manner while preserving and, where necessary, restoring freshwater ecosystems. Resources available in this sub-theme include strategic decision-making guides, government funding information, and detailed urban policies on river basin management.
