Caught between concrete and panic, India should not maladapt to climate change, Pg11

Key Highlights:

• India faces a dilemma in coastal climate adaptation, choosing between engineering solutions and managed retreat for its 11,098.81 km coastline.
• The article warns against maladaptation, where engineering solutions worsen long-term climate impacts or create social inequity.
• It advocates for a hybrid strategy that integrates law, policy, and engineering, prioritizing social equity.
• Key proposals include developing "receiver cities", reforming coastal land laws, and treating climate-displaced people as "pioneers".
• Emphasis is placed on nature-based solutions like mangroves and wetlands over hard concrete structures.

Detailed Insights:

• Many high-income countries favor managed retreat, while South Asian governments often opt for concrete walls for coastal protection.
• Examples of maladaptation include Nigeria's "Great Wall of Lagos" accelerating erosion in neighboring areas and Vietnam's dikes causing the Mekong delta to sink.
• In India, the Kosi river embankments have led to catastrophic floods by raising the riverbed.
• Managed retreat, as articulated by the IPCC, involves purposeful movement of people and assets from high-risk zones.
• Global North examples include U.S. Hazard Mitigation Grants for buyouts and U.K.'s "managed realignment" creating salt marshes.
• In India, managed retreat has often been chaotic, leading to displacement and pauperization, as seen in Odisha's Satabhaya village relocation.
• The proposed "third way" includes learning from Bangladesh's Mongla port transformation into a climate-resilient town.
• India needs to reform coastal land laws to recognize informal settlements and provide state support for relocation.
• Nature-based solutions like mangroves, bioswales, and artificial reefs offer soft defenses that adapt to ocean rhythms.
• Cities like China's Ningbo and Shanghai are engineering themselves to absorb water using permeable pavements and rain gardens.

Key Concepts Involved:

• Maladaptation: Climate change adaptation that increases vulnerability or leads to negative outcomes in the long term.
• Managed Retreat: The purposeful and coordinated movement of people, assets, and infrastructure away from areas at risk of environmental hazards.
• Nature-based Solutions: Actions to protect, sustainably manage, and restore natural or modified ecosystems to address societal challenges effectively.
• Social Equity: The fair distribution of resources, opportunities, and burdens among all members of society.
