Groundswell Part 2: Acting on Internal Climate Migration 

(September 2021, 362 pages, 26.98 MB PDF). This report by CIESIN and the World Bank, CUNY Institute for Demographic Research, and Potsdam Institute for Climate Impact Research projects increased numbers of people moving within their countries of the developing world—as many as 216 million internal migrants by 2050. Hotspots of internal migration will emerge as soon as 2030, spreading and intensifying thereafter. The research improves and extends the pioneering modeling approach of the previous World Bank Groundswell report from 2018, which covered Sub-Saharan Africa, South Asia, and Latin America, now focusing on three new regions—North Africa, Central America, and the Lower Mekong—and including reviews of climate migration issues for small island developing states (SIDS) and the Middle East.
