Agricultural production is the main consumer of water. Future population growth, income
growth, and dietary shifts are expected to increase demand for water. The paper presents a …

Groundwater—the world's largest freshwater resource—is critically important for irrigated
agriculture and hence for global food security. Yet depletion is widespread in large …

We compare ensembles of water supply and demand projections from 10 global
hydrological models and six global gridded crop models. These are produced as part of the …

Green water––rainfall over land that eventually flows back to the atmosphere as
evapotranspiration––is the main source of water to produce food, feed, fiber, timber, and …

People use lots of water for drinking, cooking and washing, but significantly more for
producing things such as food, paper and cotton clothes. The water footprint is an indicator …

This study quantifies the green, blue and grey water footprint of global crop production in a
spatially-explicit way for the period 1996–2005. The assessment improves upon earlier …

Crop production is the single largest cause of human alteration of the global nitrogen cycle.
We present a comprehensive assessment of global nitrogen flows in cropland for the year …

China's water policies in the past decades have relied heavily on the construction of
massive water conservancy projects in the form of dams and reservoirs, water transfer …

Human activities exert global‐scale impacts on our environment with significant implications
for freshwater‐driven services and hazards for humans and nature. Our approach to the …

The human influence on the global hydrological cycle is now the dominant force behind
changes in water resources across the world and in regulating the resilience of the Earth …
