Syllabus: Urbanisation   Context: By 2070, India’s urban population is projected to touch 1 billion, making cities the fulcrum of growth. However, rising risks from floods, heat waves, cyclones, and earthquakes highlight the urgency of climate-resilient urban planning.   Current Climate Vulnerabilities in Indian Cities Flooding: Unchecked urbanisation, poor drainage → two-thirds of residents at risk; projected damages > $30 billion by 2070. Extreme Heat: Urban Heat Island effect → cities hotter by 3–5°C, worsening mortality, health risks, and productivity loss. Transport: Nearly 25% of roads flood-prone; even partial waterlogging can paralyse urban mobility. Housing: Over half of future housing yet to be built; poor design can lock in risks for decades. Municipal Services: Weak drainage, waste, and energy networks worsen shocks and pollution.   Why Climate-Resilient Cities are Needed Safeguard Lives: Preparedness against floods/heatwaves reduces mortality and displacement. Protect the Economy: Cities contribute 70%+ of GDP and jobs; resilience safeguards economic continuity. Inclusion: Poor and migrants are most exposed; resilient design ensures equity. Cost-Effective: Proactive adaptation lowers future losses and attracts global investment.   Key Challenges Weak ULBs: Limited capacity, finances, and expertise for resilience planning. Fragmented Governance: Overlapping roles among states, ULBs, and parastatals slow decision-making. Financial Constraints: Low municipal revenues; limited access to global climate finance. Poor Planning: Encroachment on wetlands/floodplains amplifies vulnerability. Inequality: Informal settlements remain exposed to hazards with minimal protection.   Indian Initiatives NAPCC & SAPCCs: Frameworks for mainstreaming climate action. Sustainable Habitat Mission: Greener buildings, transport, and waste systems. Smart Cities Mission & AMRUT: Incorporate resilience into infrastructure. Heat Action Plans: Initiated in Ahmedabad; now scaled nationwide. PMAY-Urban: Scope for integrating climate-smart housing.   Strategies for Resilience Urban Planning: Compact cities; disaster-resistant building codes; zoning restrictions in high-risk areas. Flood Management: Wetland restoration, modern drainage, predictive flood systems. Heat Resilience: Tree canopies, cool roofs, shaded walkways, adjusted labour hours. Transport Systems: Elevated, redundant networks to stay functional during floods. Municipal Services: Climate-proof sanitation, waste, and energy systems with circular economy principles. Finance & Partnerships: Mobilise PPPs, green bonds, climate funds; encourage citizen participation. Capacity Building: Training ULB staff; GIS/AI-based risk mapping; institutional strengthening.   Conclusion India’s urban future depends on building cities that can withstand climate shocks while ensuring sustainable growth, equity, and ecological balance. Climate resilience is not only about disaster response but about long-term survival and competitiveness. The window of opportunity is narrow — action must begin now.
