SEDAC Releases Delta Urban-Rural Population and Land Area Estimates, Version 1

[SEDAC - evlukang]

SEDAC is pleased to announce the release of the Low Elevation Coastal Zone (LECZ) Global Delta Urban-Rural Population and Land Area Estimates, Version 1 data set. The data set provide country-level estimates of populations and land areas in river delta- and non-delta contexts for the years 1990, 2000, 2014, and 2015 for 246 statistical areas, focusing on greater-risk zones using the global extent of low elevation zones contiguous to the coast bounded by either 5 meters or 10 meters.

Four digital elevation models were used to construct 0-5m and 5-10m low elevation coastal zones: Multi-Error-Removed Improved-Terrain Digital Elevation Model (MERIT-DEM); NASA Shuttle Radar Topography Mission Elevation Low Elevation Coastal Zones (SRTM); TerraSAR-X add-on for Digital Elevation Measurement (TanDEM-X); and CoastalDEM90 (CoastalDEM). Population distribution data were sourced from Global Human Settlement - Population
Grid R2019 (GHS-POP), SEDAC's Gridded Population of the World, Version 4, Revision 11 (GPWv4.11 UN WPP), LandScan 2015 High Resolution Population Data Set (Landscan), and WorldPop Global High Resolution Population Denominators (WorldPop).

The Low Elevation Coastal Zone (LECZ) Global Delta Urban-Rural Population and Land Area Estimates, Version 1 data set assesses current and past risks related to areas in river delta- and non-delta contexts and increased natural disasters. With this information, adaptation and mitigation strategies can be tailored to the geographic locations that exhibit risk factors.
