Website providing background on 2005 EVI; useful to interpret GIS data. From site: "A vulnerability index for the natural environment, the basis of all human welfare, has been developed by the South Pacific Applied Geoscience Commission (SOPAC), the United Nations Environment Programme (UNEP) and their partners. The index was developed through consultation and collaboration with countries, institutions and experts across the globe. This index is designed to be used with economic and social vulnerability indices to provide insights into the processes that can negatively influence the sustainable development of countries." | GIS_Data>ENVSData>Other_Sites>Global>Global_EVI>CNTRY_02_EVI_04 (Jim Proctor, Fall 2008).
