OLAS Population-based Water Stress and Risk Dataset for Latin America and the Caribbean

LAC is the most water-rich region in the world by most metrics; however, water resource distribution throughout the region does not correspond demand. To understand water risk throughout the region, this dataset provides population and land area estimates for factors related to water risk, allowing users to explore vulnerability throughout the region to multiple dimensions of water risk.

This dataset contains estimates of populations living in areas of water stress and risk in 27 countries in Latin America and the Caribbean (LAC) at the municipal level. The dataset contains categories of 18 factors related to water risk and 39 indices of water risk and population estimates within each with aggregations possible at the basin, state, country, and regional level.

The population data used to generate this dataset were obtained from the WorldPop project 2020 UN-adjusted population projections, while estimates of water stress and risk come from WRI’s Aqueduct 3.0 Water Risk Framework. Municipal administrative boundaries are from the Database of Global Administrative Areas (GADM). For more information on the methodology users are invited to read IADB Technical Note IDB-TN-2411: “Scarcity in the Land of Plenty”, and WRIs “Aqueduct 3.0: Updated Decision-relevant Global Water Risk Indicators”.

LAC区域凭借多数指标位居全球水资源最丰富的地区；然而，区域内水资源分布与需求并不匹配。为全面理解该区域的水风险，本数据集提供了与水风险相关的种群和土地面积估算数据，使用户能够深入探讨区域对多重水风险维度的脆弱性。本数据集包含拉丁美洲和加勒比海地区（LAC）27个国家在市级层面的水资源压力和风险的人口估算数据。数据集涵盖了与水风险相关的18个因素类别以及每个类别中的39个水风险指数和人口估算，支持在流域、州、国家和区域层面的聚合。用于生成本数据集的种群数据源自2020年联合国调整后的WorldPop项目人口预测，而水资源压力和风险的估算则来自世界资源研究所（WRI）的Aqueduct 3.0水风险框架。市政行政边界数据来源于全球行政区域数据库（GADM）。欲了解更多关于方法论的信息，用户可参阅IADB技术简报IDB-TN-2411：“丰饶之地的稀缺”以及WRI的“Aqueduct 3.0：更新后的决策相关全球水风险指标”。
