Understanding and forecasting human mobility in response to climatic environmental changes has become a subject of substantial political, societal, academic interest. Quantitative models exploring the relationship between factors migration patterns have been developed since early 2000s; however, different produced results that are not always consistent with one another or robust enough provide actionable insights into future dynamics. Here we examine weaknesses classical methods identify next-generation approaches potential close existing knowledge gaps. We propose six priorities for climate modeling: (i) use non-linear machine-learning rather than linear methods, (ii) prioritization explaining observed data testing statistical significance predictors, (iii) consideration relevant impacts temperature- precipitation-based metrics, (iv) examination heterogeneities, including across space demographic groups aggregated measures, (v) investigation temporal dynamics essentially spatial patterns, (vi) better calibration data, disaggregated within-country flows. Improving both accommodate high complexity context-specificity will be crucial establishing scientific consensus on historical trends projections eluded discipline thus far.

The amount of literature on environmental migration is increasing. However, existing studies exhibit contradictory results. A systematic synthesis the environment-migration relationship much needed.

Abstract In the past 15 years, research activities focusing on interlinkages between climate change and human mobility have intensified. At same time, an increasing number of actors processes sought to address in context from a policy perspective. Hitherto, has been limited terms geographical preferences as well conceptual methodological focus areas. This paper argues that evolving space, future needs become more differentiated, integrated generalized. includes concerted efforts better integrate researchers global South, improved cross‐linkages different datasets, approaches disciplines, longitudinal comparative studies development innovative qualitative quantitative methods.
