Grassland Reforestation Practices concerning Sediments
To help determine where watershed conservation can help secure water for cities, we estimated the effectiveness of five common conservation strategies: land protection,... -
Cities' average distance to surface diversion sources
The average distance to surface diversion sources is expressed in kilometers. Today, cities are looking farther beyond their limits for clean water. On average, cities retrieve... -

The Agricultural Water Stress indicator identifies agricultural water stress of agricultural land under irrigation. It is calculated as the mean annual irrigation water... -
Global upstream storage (2010)
Upstream storage measures the water storage capacity available upstream of a location relative to the total water supply at that location from 1950 to 2010. Higher values... -
Annual Stress Category
Water withdrawals or water abstractions, is the freshwater taken from ground or surface water sources and conveyed to a place of use. These, normally, are sectorial distributed... -
Global upstream protected land
Upstream protected land measures the percentage of total water supply that originates from protected ecosystems. Modified land use can affect the health of freshwater ecosystems... -
