Dry & hot extremes threaten several smart cities across India

Urban water systems, public health, and infrastructure get no breather, slashing recovery windows to near zero. “Climate extremes are no longer isolated events. Many Indian cities endure repeated dry-hot stress in short bursts, gutting urban sustainability and resilience,” lead researcher IISER’s Prof. Somil Swarnkar told TOI. Prof Vikas Punia and PhD student IISER Bhopal Vaishnavi Sahu were the part of the study along with Prof Swarnkar.

The team crafted a “Cumulative Vulnerability Index,” blending climate hazards with socio-economic metrics: human capital, environmental health, economic muscle, and quality of life. Standouts like robust education and green spaces emerged as resilience superpowers. Cities boasting strong schools, clean air, and solid infrastructure shrug off shocks better.

Conversely, spots plagued by shoddy planning, scant greenery, pollution, and weak economies teeter on the brink. “Human capital and environmental quality drive urban toughness,” the study notes.

Prof. Swarnkar urged action: “Boost environmental quality, urban green belts, education, and smart planning to slash future risks.”

The findings jolted India’s Smart Cities Mission and sustainable development push, aligning with UN goals SDG 11 (Sustainable Cities) and SDG 13 (Climate Action). Blanket national fixes won’t cut it—city-tailored strategies are key, factoring in diverse terrains from plains to peaks.

Recommendations pack heat mitigation, water savvy, greening drives, and climate-proof builds into urban blueprints. Integrate risk checks into governance, the researchers implore, to steel cities against wilder weather ahead.

“India’s urban tomorrow hinges on mastering compound extremes. Resilient planning isn’t optional—it’s survival,” Prof. Swarnkar warned. TNN
