Groundwater is by far the largest unfrozen freshwater resource on the planet. It plays a
critical role as the bottom of the hydrologic cycle, redistributing water in the subsurface and …

Population growth, economic development, and dietary changes have drastically increased
the demand for food and water. The resulting expansion of irrigated agriculture into semi …

Climate change and human activities increasingly threaten lakes that store 87% of Earth's
liquid surface fresh water. Yet, recent trends and drivers of lake volume change remain …

Terrestrial water storage (TWS) modulates the hydrological cycle and is a key determinant of
water availability and an indicator of drought. While historical TWS variations have been …

The hydrological cycle is expected to intensify with global warming, which likely increases
the intensity of extreme precipitation events and the risk of flooding. The changes, however …

Water scarcity threatens people in various regions, and has predominantly been studied
from a water quantity perspective only. Here we show that global water scarcity is driven by …

Water scarcity has become a major issue to sustainable development. It can be estimated by
available fresh water resources and human water withdrawal, which are affected by both …

Rapid urbanization throughout the globe increases demand for fresh water and the
ecosystem services associated with it. This need is conventionally met through the …

Water scarcity, a critical environmental issue worldwide, has primarily been driven by a
significant increase in water extractions during the last century. In the coming decades …

We present PCR-GLOBWB 2, a global hydrology and water resources model. Compared to
previous versions of PCR-GLOBWB, this version fully integrates water use. Sector-specific …
