Integrated management of lakes, reservoirs, and their basins is critical for a climate-resilient planet: an urgent wake-up call from collective amnesia

ABSTRACT Integrated management of lakes and reservoirs and their basins is vital for preserving their significant socioeconomic and ecological benefits, which are essential for climate resilience. Lakes and reservoirs store 88% of the Earth's fresh surface water, providing water, food, energy security, flood protection, drought mitigation, and ecosystem services. This article highlights the rapid depletion and deterioration of these Lentic (standing) waters and the consequent loss of valuable benefits, threatening the global water supply and exacerbating environmental and climate crises. It discusses the evolution of lake management practices and contrasts these with strategies for managing lotic (flowing) waters. It summarizes collaborative best practices for Lake Basin Governance developed through a multiagency partnership. It reviews recent global initiatives to sustainably manage lakes, integrate storage, address aging dams, and foster partnerships and cooperation. It highlights the widespread failures across international water and environmental policies and institutions. The article calls on the global water and environmental community to awaken from collective amnesia, act, and implement best practices for governing lakes, reservoirs, and basins. Our companion article examines the institutional inertia hindering integrated action and offers collaborative opportunities for integrating land and water management in lake and reservoir basins to enhance climate resilience.
