Climate Migration: Coastal Challenges Amplified in Low-Income Regions

A recent study has illuminated a pressing issue: almost half of the world's low-income regions, particularly in Africa and Asia, may continue residing near coastlines or migrate even closer, exposing a critical gap in climate change adaptation strategies.

Research covering changes in night-time lights from 1992 to 2019 by a team from Sichuan University and Monash University revealed a diverse response in coastal subnational areas globally, with settlements retreating in more than half, stable in 28%, and drawing closer in 16%.

The findings, published in Nature Climate Change, emphasize the risk for these populations due to insufficient infrastructure and adaptive capacity, threatening efforts to achieve global climate goals as touted by the Paris Agreement. Regions in India such as Andhra Pradesh were analyzed, highlighting the dire need for robust climate strategies.
