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.

《自然资源管理指数》（NRMI）2010年版系基于生态区域保护（受保护生物群落加权平均百分比）的四个邻近目标指标的平均值构建的复合指数，涵盖了157个国家的数据。本版NRMI包含了2006年至2010年间的时序数据。值得注意的是，本版中提供的2006年至2008年的NRMI数据，由于数据和方法的变化，与NRMI 2006年至2008年版本的数据不可直接比较。该数据集由哥伦比亚大学国际地球科学信息网络中心（CIESIN）与耶鲁大学环境法律政策中心（YCELP）合作制作与分发。
