Beschreibungen/Notizen

• [...]more than 2 billion people still lack access to safe drinking water, one child dies every 17 seconds from waterborne diseases, and 3 billion people face food insecurity owing to water scarcity - numbers that could grow with the global population unless water provision improves (see go.nature.com/3jkgtry). Deforestation, land degradation and infrastructure development are also altering precipitation patterns and affecting where water comes from and ends up2. Globally, up to half of terrestrial precipitation originates from green water evaporated over land, with the rest from evaporation over the ocean3. [...]landscape changes can alter water supplies in regions downwind, as well as changing local climates and streamflows. Moisture from Chinese land also has a large role in rainfall across Central Asia and the Tibetan Plateau. [...]no country acquires over half of its moisture from within its own boundaries, implying that even the largest countries rely on evaporation from other areas to sustain their precipitation.
