DeWaard, Bajpai, and Co-Authors Estimates Climate-Induced District Out-, District-to-District, and District In-Migration in India

Posted: 3/26/2026 (CSDE Research)

CSDE External Affiliate Jack DeWaard (Saint Martin’s University) and colleagues recently published the paper, “Climate-induced internal migration in India: Looking into the past to understand the present,” in Regional Environmental Change. In addition to the research itself, this paper was lead-authored by Rimjhim Bajpai, an early career researcher who recently started her PhD in Demography at the University of Vienna and works as a Researcher on the project, “Climate change and human [im]mobility: The role of compound and cascading risks (2C-RISK)”, under the direction of Roman Hoffman at IIASA. The paper employs a novel statistical approach to estimate district out-migration, district-to-district migration, and district in-migration around 2021 by leveraging data from the 2001 and 2011 censuses alongside temperature and precipitation extremes derived from historical climate records from 1961 to 2021. Results reveal significant associations between climatic extremes, both positive and negative, and migration flows, underscoring the role of climate stressors in shaping migration decisions.
