Syllabus: Population and Migration
Source: TH
Context: Rising climate-induced droughts in Bundelkhand and floods along Bangladesh’s Jamuna River have spotlighted climate migration as a growing livelihood crisis across South Asia.
About Climate Migration:
- What is Climate Migration?
-
- Climate migration refers to the forced movement of people due to climate-related events like floods, droughts, cyclones, or slow-onset changes such as sea-level rise or desertification.
- Annual Impact: As per the International Refugee Assistance Project (2022), 20 million people are internally displaced by climate disasters every year.
- Nature: These movements are often seasonal, cyclical, or permanent, with poor households most vulnerable.
- Data & Case Examples:
-
- Bundelkhand: Faced 8–9 droughts between 1998–2009; temperatures expected to rise by 2–3.5°C by 2100. (IMD)
- Charpauli (Bangladesh): Lost 500+ houses in 1 week due to Jamuna River erosion in 2022 and riverbanks eroding by 12–52m annually.
- Vidarbha-Marathwada: Migrants Walk hundreds of kilometres for sugarcane cutting, facing 50°C+ temperatures and erratic rains.
Factors Pushing Climate Migration:
- Drought & Rainfall Variability: In Bundelkhand and Marathwada, failed monsoons and delayed rains have collapsed agriculture.
- Flooding & River Erosion: Charpauli village shows how river swelling from glacial melt/floods leads to loss of homes.
- Heatwaves & Water Scarcity: Maharashtra’s sugarcane belt records extreme heat and water-stressed agriculture, pushing labour migration.
- Debt & Income Collapse: Crop failure leads to bonded seasonal labour (e.g., ₹50,000–₹5 lakh sugarcane advance trapping koita couples).
- Loss of Livelihood Assets: Soil degradation, arable land erosion, and rising input costs in climate-sensitive regions worsen distress.
Implications of Climate Migration:
- Rural Displacement: Entire families are leaving villages, altering demographic and land-use patterns.
- Urban Informality: Migrants often settle in slums without sanitation, housing, or safety nets (e.g., Bundelkhand migrants in Delhi).
- Gendered Risks: Women left behind face sexual violence, financial burden, and school dropouts among children.
- Labour Exploitation: Contract-bound cane cutters must work without exit, creating modern debt bondage.
- Erosion of Social Structures: Long-term migration breaks rural social support systems and collective farming resilience.
Challenges with Climate Migration
- No Legal Recognition: India lacks a legal category for climate migrants, making them invisible in welfare schemes.
- Lack of Social Security Portability: Migrants lose access to ration cards, pensions, MGNREGA at new locations.
- Poor Working Conditions: Living in plastic tents without water, electricity, or sanitation (e.g., Maharashtra cane cutters).
- Debt Cycle: Wages tied to harvest output amid falling yields trap families in multi-year debt cycles.
- Data Deficit: No centralized climate migration monitoring system, making policy response slow and under-informed.
Way Forward:
- Legal Recognition: Integrate climate-displaced persons under national migration and disaster frameworks (e.g., NDMA Act).
- Social Protection Portability: Use One Nation One Ration Card and eShram to ensure benefit access during migration.
- Climate-Resilient Rural Employment: Expand MGNREGA for water conservation, drought-proofing, and agroforestry.
- Skill Diversification: Provide mobile skill training and job matching for seasonal migrants (like koita couples).
- National Climate Migration Index: Create a district-level vulnerability map integrating IMD, Census, and SECC data for early action.
Conclusion:
Climate migration is no longer a distant threat—it is India’s lived reality, especially for the rural poor. Without adaptive policy and protective social infrastructure, migration will remain a forced displacement rather than a choice. Inclusive growth must now account for mobility, dignity, and resilience in the face of climate change.
