Quantitative empirical studies investigating how climate and other environmental factors affect migration are increasing year by year. PIK scientists have reviewed the methodological approaches used in the quantitative climate migration literature. Their reviews 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 have reviewed about 130. Empirical research We identified the challenges of climate migration from a methodological point of view and finally provided methodological recommendations based on the state-of-the-art approach to the Institute’s research methods, “said Kira Vinke. The PIK scientist Barbora Sedova, who went, explains. And Roman Hoffman.

Although the majority of studies agree Climatic conditions It is important for the migration and the results will vary significantly. 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 findings is the difference in the empirical approach adopted in the analysis, according to the authors of the study.

Scientists provide an overview of common 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 investigating contextual impacts and mechanisms.

Finally, this review also has important implications for policy makers and practitioners working on climate change. Barbora Sedova says, “By emphasizing the diverse challenges that exist, we want our users to realize that the interpretation of findings 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 more and more serious, leading to a variety of stakeholders, including researchers from Global South and representatives of communities directly affected by climate change. More solution-oriented and policy-oriented research involving them is needed.
