At what scales are the indicators available?

Submitted by admin on Wed, 05/13/2015 - 14:04

Indicators are available at one or more of the following geographic scales:

  • Site scale: Site scale data are currently available at two levels.
    • Protected Areas are delineated using the World Database of Protected Areas (WDPA), the most comprehensive global database on terrestrial and marine protected areas. The WDPA is compiled by UNEP-WCMC with support from the IUCN World Commission on Protected Areas.
    • Key Biodiversity Areas (KBAs) are sites contributing significantly to the global persistence of biodiversity. They are identified using globally standard criteria and thresholds, based on the needs of biodiversity requiring safeguards at the site scale. KBA criteria have recently been revised by a task force of the World Commission on Protected Areas. KBA-level data are currently available only in countries overlapping the MacArthur Foundation's focal regions (see Regional Scale, below).
  • Basin scale: River basin (i.e., watershed) scales (for basins located inside of country boundaries) are delineated using HydroShed, compiled as sub basins and published by FAO, 2012. For some indicators, basin-scale data are only available for basins overlapping the MacArthur Foundation's focal regions (see Regional Scale, below).
  • Country scale: Analyses were performed at the national scale for most indicators. The country areas analyzed are the entire country, including offshore islands.
  • Regional scale: Regional scale data are currently available for a few indicators at up to three levels.
    • MacArthur Foundation focal regions encompass the Tropical Andes of South America, the Great Lakes of East and Central Africa, and the Greater Mekong of Southeast Asia. Each region is delimited by their constituent major river basins.
    • FAO Global Ecological Zones are used by the Global Forest Resources Assessment (FRA) of the Food and Agriculture Organization of the United Nations (FAO) to present global and regional forest data. The FAO defines these zones as “a zone or area with broad yet relatively homogeneous natural vegetation formations, similar (not necessarily identical) in physiognomy. Boundaries of the EZs approximately coincide with the map of Köppen-Trewartha climatic types, which was based on temperature and rainfall. An exception to this definition are ‘Mountain systems,’ classified as one separate EZ in each Domain and characterized by a high variation in both vegetation formations and climatic conditions caused by large altitude and topographic variation.” The EZ map used by the Dashboard corresponds to the 2010 update, which mapped 19 different EZs.
    • CBD/WDPA regional divisions are used by the Convention of Biological Diversity (CBD) and the World Database of Protected Areas (WDPA) to summarize regional statistics based on geographically sensible country groups. There are 10 regional divisions including Africa, Asia, Caribbean, Central America, Europe, Middle East, North America, Oceania, South America, and Southern Oceans. The list of countries that these regional divisions encompass can be find in Annex 2 of the 2014 United Nations List of Protected Areas report
