The UN Environment GEMS/Water Data Centre was established within the International Centre for Water Resources and Global Change, a UNESCO Category 2 Centre hosted by the German Federal Institute of Hydrology (BfG, by its acronym in German) in Koblenz. Its objectives include collecting, controlling and providing water quality monitoring data and products for regional and global water quality assessments. The Data Centre maintains the global water quality database and information system GEMStat. Data for GEMStat is received from GEMS/Water's global network of National Focal Points (NFP's) which are government institutions and agencies with the official mandate to monitor freshwater quality data in their country.
