Electrical conductivity
Units: Micro-Siemens/Centimeter
Units: The country values represent averages of the station-level values for the three year time period 1994-96, except where data were only available for an earlier time period (1988-1993). The number of stations per country varies depending on country size; number of water bodies; and level of participation in the GEMS monitoring system. |
Percent of country's territory under severe water stress
Units: Percent of Land Area
Units: This data is derived from the WaterGap 2.1 gridded hydrological model developed by the Center for Environmental Systems Research, University of Kassel, Germany. The modellers derived, for each country, grid cell by grid cell estimates of whether the water consumption exceeds 40 percent of the water available in that particular grid cell. These were then converted to land area equivalents in order to calculate the percentage of the territory under severe water stress. |
