In Senegal, under the Belmont Forum-funded project “Climate-Induced Migration in Africa and Beyond: Big Data and Predictive Analytics” (CLIMB), DPA and its academic and civil society partners used “traditional” and “non traditional” data sources, including mobile phone data, to study human mobility induced by extreme weather events. This project, enabled by OPAL technology, integrated Call Detail Records (CDRs) provided in partnership by Orange-Sonatel, were layered with earth observation, social media, survey, and official statistical data. This comprehensive approach enabled a detailed analysis of migration processes, shedding light on the influence of multilevel factors like climate, social, economic, sociological, and cultural aspects.
