"The World Database on Protected Areas (WDPA) is compiled from multiple sources and is the most comprehensive global dataset on marine and terrestrial protected areas available. It is a joint venture of UNEP and IUCN, produced by UNEP-WCMC and the IUCN World Commission on Protected Areas (IUCN-WCPA) working with governments and collaborating NGOs. Over the last 12 months UNEP-WCMC, supported by the Proteus Partnership, has been redeveloping the World Database on Protected Areas. Using the latest GIS, web and database technologies the WDPA has been extensively redesigned into a web-enabled spatial database platform with custom data editing, downloading and analysis facilities. Over the course of the next 16 months, the opportunities to interact with the new WDPA will be slowly unveiled."
