Rapid urbanization cupped with climate-induced migration making the cities more exposed to recurrent climate extremes. Most rural to urban migrants move towards mega/primary cities for better livelihood opportunities creating an overburden on the existing dense population. This study developed a framework for building climate-resilient secondary cities to divert the displaced people rather than overcrowded megacities. To develop a town/city-wide climate adaptation plan by the citizens, the study has used a Locally-Led Adaptation (LLA) approach. This paper proposes a comprehensive seven-step approach for the implementation of a climate-resilient migrant-friendly town model. The steps outlined include city selection, establishment of a local adaptation center, identification of climate-vulnerable migrant hotspots, formulation of Local Climate Action Plans (LCAP), Ward-level Climate Action Plans (WCAP), and Town-level Climate Action Plans (TCAP), and scaling up. This structured approach will help to address the multifaceted challenges posed by climate change-induced migration and foster sustainable development in vulnerable communities. Acknowledging the diverse geographical and economic contexts of different locations, the model emphasizes the need for tailor-made strategies.
