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... -
Major River and Lake Basins of the World
The dataset comprises the GIS layer of 405 major river and lake basins of the world. Data was collected within the framework of the BGR-UNESCO "World-wide Hydrogeological... -
Global flood occurence (1985-2011)
Flood occurrences is the number of flood recorded from 1985 to 2011. Flood counts were calculated by intersecting hydrological units with estimated flood extent polygons. -

Global return flow ratio
Return flow ratio measures the percent of available water previously used and discharged upstream as wastewater. Higher values indicate higher dependence on treatment plants and... -
Agricultural Water Stress in Transboundary River Basins
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... -
