This STAP paper examines how the global hydrological cycle connects climate, biodiversity, land, ecosystems, and human well-being across scales, and argues that water should no longer be managed primarily through fragmented, blue-water approaches focused on rivers, lakes, and aquifers alone. The paper highlights the growing importance of green water, atmospheric moisture flows, and land–atmosphere interactions in shaping water security, ecosystem resilience, and global environmental outcomes in an era of accelerating climate change and environmental degradation. It calls for the Global Environment Facility to adopt a more integrated, systems-based approach in GEF-9 programming by strengthening cross-focal area coherence, embedding hydrological linkages across projects and Integrated Programs, improving the evidence base on blue and green water dynamics, and advancing multi-level governance and cooperation to generate Global Environmental Benefits alongside broader socioeconomic and peace co-benefits.
Summary Climate change is intensifying water scarcity and amplifying upstream-downstream tensions in transboundary river basins, particularly in Central Asia. We present a multiscale framework integrating hydrological dynamics with the water-food-energy (WFE) nexus to assess climate-driven cross-sectoral trade-offs in...

The two-way feedback between societies and water systems is investigated using the socio-hydrology framework. This study evaluates how climate change and wetlands governance, as well as feedbacks, generate socio-hydrological pathways in the human–water system. The paper draws comparative lessons from six contrasting ba...

Climate change is altering hydrological regimes across the Amazon Basin, with implications for water security, freshwater ecosystems, and climate adaptation planning. This study analyzes projected multiannual and seasonal streamflow changes for 2015–2050 under SSP3-7.0 and SSP5-8.5 using HydroBID, building on a previ...
Terrestrial ecosystems operate through tightly coupled interactions among soil systems, vegetation, hydrological processes, and biogeochemical cycles. Forests, agricultural landscapes, and natural resource systems collectively shape ecosystem resilience, productivity, and biosphere stability. This mini review synthesiz...
As a core region for ecological security, food production, and energy supply in China, the hydrological cycle of the Yellow River Basin is being profoundly altered by climate change and intensive human activities, leading to growing systemic water scarcity and increasingly heterogeneous hydrological processes. However,...
