Irrigation accounts for~ 70% of global freshwater withdrawals and~ 90% of consumptive
water use, driving myriad Earth system impacts. In this Review, we summarize how irrigation …

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

Terrestrial water storage (TWS) over the Tibetan Plateau, a major global water tower, is
crucial in determining water transport and availability to a large downstream Asian …

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 …

Droughts that exceed the magnitudes of historical variation ranges could occur increasingly
frequently under future climate conditions. However, the time of the emergence of …

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 …

Rapid urbanization throughout the globe increases demand for fresh water and the
