A New Report Posits Potential Mobility in Africa from Climate Impacts

February 7, 2023

A new report from the Africa Climate Mobility Initiative (ACMI), African Shifts: Addressing Climate-Forced Migration depicts African people’s experience of climate vulnerability and presents possible scenarios for movements due to climate impacts on the continent between now and 2050. Finally, it presents eight key recommendations to be implemented between now and 2030 that focus on constructive, adaptive responses to climate mobility, in alignment with the 2030 Sustainable Development Goals and the Paris Agreement.

CIESIN contributed to the report by producing spatially explicit projections of both internal and international mobility that may occur from climate impacts, within and among African countries, up to the year 2050. This modelling builds on the innovative approaches of the World Bank’s Groundswell series of reports, for which CIESIN worked with City University of New York and the Potsdam Institute for Climate Impact Research on the modeling. The modeling work was complemented with findings from field research conducted by the Mixed Migration Centre.  

The ACMI is a joint undertaking between the African Union Commission, the United Nations Development Programme (UNDP), the UN Framework Convention on Climate Change (UNFCCC), the International Organization for Migration (IOM), and the World Bank. The CIESIN team was led by Alex de Sherbinin, deputy director and senior research scientist, and included Fabien Cottier, postdoctoral research scientist; Susana Adamo, research scientist; Briar Mills, former geographic information specialist; Greg Yetman, associate director for Geospatial Applications; Tricia Chai-Onn, senior geographic information specialist; and John Squires, geographic information specialist.

New SEDAC Data Releases Include First-Ever Global Poverty Grid

Several new data products have been released under CIESIN’s NASA-funded Socioeconomic Data and Applications Center (SEDAC). Foremost among them, the Global Gridded Relative Deprivation Index (GRDI) measures relative poverty and deprivation using subnational data on human development, infant mortality, and child dependency, as well as satellite-derived data on built-up areas, nighttime lights, and change in nighttime lights. It is the first product of its kind that covers the entire world at a 1 kilometer spatial resolution. Other new data sets from the NASA SEDAC include:

Daily and Annual Air Quality Data Sets for the Contiguous U.S. support research in environmental epidemiology, environmental justice, and health equity by linking with ZIP Code-level demographic and medical data sets.

Country Trends in Major Air Pollutants, a framework of public-health-focused air quality indicators that measures more than 200 countries' trends in exposure to particulate matter (PM2.5), ozone (O3), nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), and volatile organic compounds (VOCs). Developed by an interdisciplinary team from Yale University with NASA SEDAC.

Urban and Land Backscatter Time Series. Based on satellite microwave backscatter, the data set traces trends in urban settlements from 1993 to 2020. Developed by a team led by Steve Frolking, University of New Hampshire.

Twentieth Century Crop Statistics, a crop yield data set spanning the period 1900‒2017 provides national and subnational data on production, yield, and harvested area of maize and wheat for many of the world’s major bread baskets. Developed by W. Anderson and others.

Water Security Monthly Grids. Monthly surpluses and deficits of freshwater, computed on a 0.25 degree grid for 1948‒2014. Developed with ISciences.
