As part of the United Nations Environment Programme’s World Conservation Monitoring Centre’s (UNEP-WCMC) efforts to achieve the Aichi Biodiversity Targets, recent revisions have taken place on the existing system of terrestrial ecoregions of the world. To capture a more relevant and updated outlook on the ecoregions of the Arabian Peninsula, UNEP-WCMC collaborated with AGEDI to incorporate the latest Geographical Information Systems (GIS) data on hand. As a result, AGEDI’s Local, National and Regional Biodiversity Rapid Assessment data has been set as a standard tool for the region to monitor the progress towards achieving the Aichi Targets.
