Africa Climate Mobility Initiative (ACMI): Internal Migration Projections

Description

The Africa Climate Mobility Initiative (ACMI) Internal Migration Projections project internal migration flows at 5-year intervals from 2020 to 2050 for a combination of 2 sets of Shared Socioeconomic Pathways (SSPs) scenarios and 3 sets of Representative Concentration Pathways (RCPs) scenarios. The unit of analysis is 7.5 arc-minutes, covering the entire African continent (approximately 15 km at the equator). These grid cells are drawn using a vector representation, and not a tessellation of grid cells (rasters). While the calibration and projection took place at a grid cell resolution of 2.5 arc-minutes, these data have been aggregated to a 7.5 arc-minute resolution. These data underpin the African Shifts Report, produced by the ACMI and enabled by the Global Centre for Climate Mobility (GCCM). The ACMI was launched in September 2021 as a joint initiative of the GCCM, the African Union Commission (AUC), the United Nations System (UN), and the World Bank.

21 The data are available in two different versions: country specific and Africa-wide. The first version of the data set provides grid cell-level data for all countries individually, while the second version combines the data from all the countries into a single file. Both versions are available in Geodatabase (GDB) and GeoPackage (GPKG) formats and are packaged as compressed zip files containing PDF Documentation which includes a data dictionary. The documentation is available at https://cmr.earthdata.nasa.gov/search/concepts/C3393310301-SEDAC.html. https://search.earthdata.nasa.gov/search/granules?p=C3393310301-SEDAC
