Quantitative empirical studies examining how climate and other environmental factors affect migration are increasing year by year. PIK scientists reviewed the methodological approaches used in the quantitative literature on climate migration. Their journals play an important role in assessing how climate factors affect human migration and provide guidance to researchers studying climate migration.

“The survey method shapes our understanding of climate change. We looked at around 130 of them. Empirical research We identified the challenges of climate migration from a methodological perspective and ultimately provided methodological recommendations based on the Institute’s cutting-edge research method approach, ”said Kira Vinke. PIK scientist Barbora Sedova, who went there, explains. And Roman Hoffmann.

Although the majority of studies agree Weather conditions This is important for the migration and the results will vary widely. For this reason, it is difficult to determine when and under what conditions climate change will occur. One of the reasons for the non-uniformity of the results is the difference in the empirical approach taken in the analysis, according to the study authors.

Scientists provide an overview of current methodological approaches and provide evidence of their potential impact on climate impact estimates. It also identifies five key challenges related to measuring migration and climate events, integrating and aggregating data, identifying causality, and studying contextual impacts and mechanisms.

Finally, this review also has important implications for policy makers and practitioners working on climate change. Barbora Sedova says: “By focusing on the various challenges that exist, we want our users to realize that the interpretation of results and conclusions is too simple. The underlying relationships of climate change are complex and meta. As the analysis shows, the threat of climate change to local livelihoods is becoming increasingly serious, leading to a variety of stakeholders, including researchers from southern countries and representatives of communities directly affected by the climate change. More research focused on solutions and policies involving them is needed.
