Overview

Causal mediation analysis reveals social networks influence migration decisions in rural households during flooding, suggesting new adaptation strategies.

Key Points

  • This research aims to explore the role of social networks in mediating the impact of flooding on migration decisions in Malawi.
  • Utilized 2019/2020 Malawi Living Standards Measurement Survey and geospatial flood data.
  • Employed causal mediation analysis with control function and Lewbel approaches to address endogeneity.
  • Performed Heckman correction, propensity score matching, and Rosenbaum bound sensitivity tests to mitigate selection bias.
  • A significant mediation effect of 0.041 percentage points corresponds to a 2.41% reduction in migration.
  • The mediation effect is statistically significant only for low-intensity flooding (SPI ≥ 1) among rural households.
  • Findings suggest social networks serve as risk-coping mechanisms for vulnerable populations.
