GEMET

The keyword system used is based on GEMET (GEneral Multilingual Environmental Thesaurus) - a thesaurus system developed for the European Topic Centre on Catalogue of Data Sources and the European Environment Agency. It contains over 5,000 keywords, organised in a hierarchical structure under 40 themes.

For this EIS, some additional keywords have been added to the GEMET to cater for some Namibian and southern African concepts that were not adequately covered.

For more information on GEMET go to the EIONET website.
