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年版是由174个国家的四个近目标指标的平均值构成的复合指数，这些指标包括生态区域保护（受保护生物群落加权平均百分比）、改善卫生条件、改善水源和儿童死亡率。2011年版的NRMI包含从2006年至2011年的NRMIs的一致时间序列。此外，2011年版的NRMI还包括两个新的指标，这些指标将最终取代NRMI：一个是自然资源保护指标（NRPI），它仅由生态区域保护指标组成；另一个是儿童健康指标（CHI），它是获取水源、卫生条件和儿童死亡率接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和政策中心（YCELP）合作生产与分发。
