West Africa Coastal Vulnerability Mapping: Gridded Subset of Sub-national Poverty and Extreme Poverty Prevalence

The West Africa Coastal Vulnerability Mapping: Gridded Subset of Sub-national Poverty and Extreme Poverty Prevalence represents the HarvestChoice Subnational Poverty and Extreme Poverty Prevalence data set as a one kilometer raster, and includes values within 200 kilometers of the coast. Poverty levels affect the "defenselessness" of populations in the low elevation coastal zone. These data were developed by the Harvest Choice project funded by the Bill and Melinda Gates Foundation. Harvest Choice measured 2005 poverty levels using 2005 purchasing power parity data for two thresholds: $1.25/day and $2/day international poverty lines. The $2/day threshold was selected for this mapping exercise.

《西非沿海地区脆弱性映射：省级贫困和极端贫困患病率栅格子集》代表HarvestChoice省级贫困和极端贫困患病率数据集，以一公里栅格形式呈现，并包含距离海岸线200公里范围内的数值。贫困水平影响着低海拔沿海地带人口的‘脆弱性’。这些数据由Bill and Melinda Gates Foundation资助的Harvest Choice项目开发。Harvest Choice项目使用2005年的购买力平价数据，针对1.25美元/天和2美元/天的国际贫困线标准，对2005年的贫困水平进行了测量。在本次映射练习中，选取了2美元/天的贫困线标准。
