Why in news?
Persistent droughts in Bundelkhand and recurrent floods along Bangladesh’s Jamuna River illustrate how climate change is driving people to migrate. The discussion emphasises the need to recognise and address climate‑induced migration.
Understanding climate migration
- Definition: Movement of people within or across borders triggered primarily by climate‑related events such as droughts, floods, sea‑level rise and heatwaves.
- Case examples: Farmers in Bundelkhand and Vidarbha–Marathwada are abandoning agriculture due to chronic drought, while communities in the Char districts of Bangladesh and Assam migrate repeatedly because of riverbank erosion and flooding.
- Push factors: Erratic rainfall, declining groundwater, soil degradation, tropical storms, loss of crops/livestock, mounting debts and socio‑economic marginalisation.
Implications
- Urban stress: Migration increases the population of informal settlements in cities, straining infrastructure and services.
- Gendered vulnerabilities: Women and children face higher risks of exploitation, trafficking and disrupted education.
- Labour exploitation: Migrants often work in informal sectors without legal protection, leading to wage theft and unsafe conditions.
- Cultural erosion: Traditional livelihoods, languages and social networks erode when communities disperse.
Challenges and policy responses
- Lack of legal recognition: Climate migrants are not recognised under refugee law, limiting access to rights and assistance.
- No portability of social protection: Welfare benefits tied to place of origin do not travel with migrants, leaving them without safety nets.
- Data deficit: No official mechanism tracks climate‑induced displacement; planning is reactive rather than proactive.
- Way forward: Enact laws recognising climate migration, enable portability of ration cards, pensions and health insurance; create climate‑resilient rural jobs (e.g., drought‑resistant agriculture, water harvesting); diversify skills; and develop a national climate migration index to guide targeted interventions.
