To fill the data gap, UN Environment and Google have collaborated with the European Commission’s Joint Research Centre and launched this Water-Related Ecosystems platform, aiming at providing free and open access to national, sub-national, basin and sub-basin aggregated data on water extent. Satellite-based Earth observations on this site partially supplement countries’ in situ monitoring and nationally reported data. Currently the site covers only parts of indicator 6.6.1 components (i.e. change in spatial extent of open water bodies) but will include others (e.g. water quantity and quality, natural and artificial water bodies, etc.) in the future.
