Dr. Jonas Bergmann



Dr. Jonas Bergmann has recently worked for the Climate Migration Council (CMC), Emerson Collective, and the Thematic Working Group on Environmental Change and Migration of the Global Knowledge Partnership on Migration and Development (KNOMAD) at the World Bank.

Prior, he conducted his doctoral research at the Potsdam Institute for Climate Impact Research (PIK) on climate change and migration, in particular in Peru. His work supported pertinent stakeholders in developing a governance approach to the topic. In his dissertation at Humboldt-Universität zu Berlin, he applied mixed methods to analyze the objective and subjective well-being impacts of different forms of climate (im)mobilities across Peru's three large regions: the coastal desert, the highlands, and the Amazon rainforest. After finalizing the PhD research, he continued to contribute to PIK as a guest researcher.

Dr. Bergmann has consulted for the Climate Migration Council (CMC); Emerson Collective; the Organisation for Economic Co-operation and Development (OECD) Development Centre and its Development Co-operation Directorate's Crises and Fragility Team; the Global Knowledge Partnership on Migration and Development (KNOMAD) Working Group on Migration and Environmental Change in Washington D.C.; as well as for the World Bank’s Climate Policy Team. His publications have covered various aspects of environmental migration and displacement, and he is co-author of the highly cited World Bank’s flagship report "Groundswell" on internal climate migration. Dr. Bergmann has also worked as a research associate at the Global Public Policy Institute (GPPi) in Berlin, where he conducted research on protecting people in mixed migration settings in West Africa.

In addition, Dr. Bergmann's teaching includes a block seminar on Climate Risks and Migration at the University of Dresden. He has also worked and interned with the Institute for the Study of International Migration, Human Rights Watch, the Berkley Center for Religion, Peace and World Affairs, the International Human Rights Unit of the German Foreign Service, and the Chilean National Human Rights Institute. Furthermore, he has participated in various refugee and migration networks as well as co-founded two NGOs for migrant empowerment in Germany and the U.S.

Dr. Bergmann defended his dissertation on the well-being impacts of climate (im)mobilities with magna cum laude at Humboldt-Universität zu Berlin. He received his Master of Science in Foreign Service from Georgetown University in Washington, D.C., and completed his bachelor’s degree in International Affairs in Dresden, Valparaíso (Chile), and Lyon (France). His studies, both completed with summa cum laude, have been supported by the Fulbright Commission, the German Academic Exchange Service (DAAD), Georgetown University, the German National Academic Foundation, and the German Economy Foundation.

Dr. Bergmann speaks German, English, Spanish, and French. He is member of the Population-Environment Research Network of IUSSP (PERN), the AKGeographie Migrationsforschung, the Young Earth System Scientists community (YESS), and the Young Policy Network on Migration (YPNM, funded by Mercator Foundation Switzerland and NCCR).
