1. Average precipitation (1961–90 from IPCC (mm/year). As in the FAO-AQUASTAT Database, for some countries large discrepancies exist between national and IPCC data on rainfall average. In these cases, IPCC data were modified to ensure consistency with water resources data.

2. Outflow – Sep. 2004 for surface water and Aug. 2005 for groundwater.
