Natural Resource Management Index (NRMI), 2011 Release

The Natural Resource Management Index (NRMI), 2011 Release is a composite index for 174 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 2011 release of the NRMI includes a consistent time series of NRMIs for 2006 to 2011. In addition, the 2011 release includes two new indicators that will eventually supplant the NRMI: a Natural Resource Protection Indicator (NRPI) that is solely composed of the eco-region protection indicator, and a Child Health Indicator (CHI), which is an unweighted average of the proximtiy-to-target scores for access to water, access to sanitation, and child mortality. 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）2011版》系针对174个国家的一项综合指数，该指数基于生态区域保护（受保护生物群落所占加权平均百分比）、改善卫生设施的可及性、改善水资源可及性以及儿童死亡率四个邻近目标指标的算术平均值。NRMI 2011版包含了2006年至2011年连续时间序列的NRMIs。此外，2011版还新增了两个指标，这些指标将最终取代NRMI：一是自然资源保护指标（NRPI），该指标仅由生态区域保护指标构成；二是儿童健康指标（CHI），该指标为水、卫生设施可及性及儿童死亡率邻近目标分数的无加权平均值。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与政策中心（YCELP）共同制作并分发。
