The knowledge base
Good decisions are based on sound knowledge. In environmental decision-making, this means understanding the state of the environment and the drivers of environmental change, as well as tracking global responses to change. Data from individual countries can be collated to form worldwide information resources, which enable global targets to be set and progress towards them measured.
At UNEP-WCMC we work with partners around the world to bring together, manage and keep updated several critically important global data sets. Our partners help us bring together national data in standard formats that can be compiled and compared with data from other countries.
The World Database on Protected Areas (WDPA) is the world’s most comprehensive database on terrestrial and marine protected areas and just one of the major databases managed by UNEP-WCMC. Spatial data from governments and collaborating non-governmental organizations are regularly updated and made easily available via the online interface, Protected Planet. Managed in partnership with the International Union for Conservation of Nature’s World Commission on Protected Areas, the WDPA contains approximately 200,000 records. The wealth of knowledge provided by the WDPA facilitates better decision-making and has made it easier to set, and assess progress towards, the Aichi Biodiversity Targets.
