Climate-Induced Displacement: Key Reasons & Consequences
- Climate change is drastically altering India’s 7,500 km coastline, with over 34% already facing erosion. Rising sea levels, projected to increase by 0.3–0.7 meters by 2100 (IPCC), along with saltwater intrusion and unregulated development, are displacing traditional farming and fishing communities.
- Over 3 million people in low-lying coastal areas are at risk, many of whom are being pushed into insecure urban jobs lacking legal protection or state support.
Climate Induced Displacement: Current Facts and Data
| Coastal Erosion Extent | Over 33.6% of India’s 7,500 km coastline is eroding, posing a threat to coastal settlements. |
| Annual Climate Displacement | 3.6 million Indians are displaced each year due to disasters including coastal hazards. |
| Future Risk Projection | An estimated 45 million Indians may be displaced by 2050 due to sea-level rise and flooding. |
| Urban Risk | Mumbai could lose more than 10% of its land by 2040, with sea levels rising up to 76 cm by 2100. |
Key Reasons for Displacement
- Sea-Level Rise: Due to a surge in coastal water levels caused by climate anomalies, e.g., Coastal community relocation in Satabhaya, Odisha.
- Coastal Degradation: In Karnataka’s Honnavar taluk, traditional fishing communities face displacement as ports, tourism projects, and mangrove destruction accelerate coastal degradation.
- Flooding: Coastal flooding during monsoon rainfall has been a common phenomenon in areas such as Tamil Nadu (Nagapattinam), Gujarat (Kutch), and Kerala.
- Infrastructure: Industrial expansion and port development have accelerated coastal degradation by deliberately clearing mangrove forests, dunes, and wetlands that traditionally protected communities.
- Weaponisation of Climate Change: Narrative of voluntary retreat from ecologically sensitive areas like coasts as part of climate action, without any strategy.
Legal Lacunae
- Lack of Legal Access: Coastal communities have limited access to protective laws. E.g., labour laws, the Prevention of Human Trafficking Act, etc.
- No Specific Legal Status: Climate migrants are protected under Article 21, but don’t get reference in any laws like the Disaster Management Act, Environmental Protection Act, etc.
- Missing Rehabilitation Strategy: NAPCC and state plans acknowledge climate risks but lack concrete frameworks for resettling displaced populations
- CRZ 2019 Priorities Skewed: Though aimed at sustainable management, CRZ 2019 favours tourism and industry over community rights.
- Violation of Informed Consent: The legal principle of ‘informed consent,’ as outlined in environmental laws, is often violated.
- Judicial Oversight Ignored: Lack of legal amendments to incorporate judicial observations has denied complete justice.
- M.C. Mehta Case: SC acknowledged and recognised the intrinsic link between the environment and fundamental rights (Article 21).
Consequences
- Social impact: Displaced communities lack basic amenities like water, education, & shelter, denying them a dignified life. Women and children face social challenges like prostitution, illiteracy, & hunger.
- Economic impact: Displaced people work in the informal economy as construction workers and guards, often for low pay, and face bonded labour in coastal urban areas like Mumbai and Chennai.
- Intimidation: Activists who fight for their rights face criminalisation, surveillance, & life threats very often.
Way Forward
- Legal Recognition: Enact policies to recognise climate-induced displacement and extend welfare entitlements such as housing and healthcare.
- Strengthen CRZ and EIA: Reinforce Coastal Regulation Zones and integrate climate risk into environmental assessments.
- Community-Led Adaptation: Promote mangrove reforestation and sustainable coastal livelihoods using local knowledge. E.g., Pattuvam, Kerala: Community-managed mangroves enhance flood resilience.
- Resilient Urban Planning: Improve rehabilitation colonies with basic services, land tenure rights, and skill-building programs.
- Gender-Sensitive Interventions: Prioritise women and children in social protection and livelihood schemes.
- Climate Finance and Governance: Leverage Green Climate Fund & decentralise adaptation planning through Panchayats. E.g., the Sundarbans, which are MGNREGS-funded, enhance local climate resilience.
Climate-induced displacement is a human rights and development crisis that demands a rights-based, inclusive response. As UN Chief António Guterres warns, “Climate change is the defining issue of our time,” and India must act with urgency and equity.
