Natural Resource Management Index (NRMI), 2010 Release

The Natural Resource Management Index (NRMI), 2010 Release is a composite index for 157 countries derived from the average of four proximity-to-target indicators for eco-region protection (weighted average percentage of biomes under protected status), access to improved sanitation, access to improved water and child mortality. The 2010 release of the NRMI includes time series NRMIs for 2006, 2007, 2008, 2009 and 2010. Note that the NRMIs for 2006-2008 provided in this release are not directly comparable to those found in the 2006-2008 releases of the NRMI owing to changes in data and methods. The data set is produced and distributed by the Columbia University Center for International Earth Science Information Network (CIESIN) in collaboration with the Yale Center for Environmental Law and Policy (YCELP), Yale University.
