Context: <\/strong>Delhi and the NCR are facing longer and more intense heatwaves due to rapid urbanisation, shrinking green cover, excessive concretisation, and rising air-conditioning use. These factors have intensified the Urban Heat Island effect, turning the city into a \u201cheat trap\u201d.<\/p>\n

Reason why Delhi is retaining heat<\/strong><\/h2>\n
    \n
  1. Concrete, asphalt, steel, and glass absorb heat during the day and release it slowly at night, preventing cooling.<\/li>\n
  2. Roads, rooftops, and facades store heat, causing surface temperatures to rise to 50\u201360\u00b0C in dense areas.<\/li>\n
  3. Glass-heavy architecture in Gurgaon and Noida increases solar radiation indoors and raises dependence on air conditioning.<\/li>\n
  4. Vehicular activity on corridors such as NH-48 creates continuous heat hotspots through engines and exhaust emissions.<\/li>\n
  5. High-density construction and narrow streets restrict airflow and trap heat within the city.<\/li>\n
  6. Traditional cooling features such as courtyards, shaded pathways, and ventilation corridors have disappeared.<\/li>\n
  7. Loss of green cover, degraded wetlands, and destruction of Yamuna floodplains have weakened natural cooling through evapotranspiration.<\/li>\n<\/ol>\n

    How does cooling further increase warming:<\/strong><\/h2>\n
      \n
    1. Air conditioners release heat outdoors while cooling interiors, thereby increasing ambient temperatures by 1\u20132\u00b0C in dense neighbourhoods.<\/li>\n
    2. Rising temperatures increase cooling demand, creating a feedback loop of more energy use and more heat release.<\/li>\n
    3. Delhi\u2019s peak electricity demand has crossed 8,000 MW during summers due to high cooling requirements.<\/li>\n
    4. Increasing cooling demand also raises pressure on power systems and increases the risk of outages during extreme heat events.<\/li>\n<\/ol>\n

      Economic and ecological impacts<\/strong><\/h2>\n

      Economic impacts<\/strong><\/p>\n

        \n
      1. Excessive heat reduces industrial and warehouse efficiency because machinery functions within temperature limits.<\/li>\n
      2. Productivity declines by 2\u20133% for every degree rise above optimal temperature levels.<\/li>\n
      3. Heat-related disruptions increase delays, operational costs, and supply chain inefficiencies.<\/li>\n
      4. Storage conditions deteriorate during extreme heat, affecting logistics and trade.<\/li>\n
      5. Delhi faces annual economic losses worth nearly $100 billion due to declining heat-related productivity.<\/li>\n<\/ol>\n

        Ecological impacts<\/strong><\/h2>\n
          \n
        1. Shrinking green cover reduces natural cooling and increases urban temperatures.<\/li>\n
        2. Degraded wetlands and disappearing water bodies weaken ecological resilience.<\/li>\n
        3. Loss of Yamuna floodplains reduces moisture retention and heat regulation capacity.<\/li>\n
        4. Increased energy consumption raises emissions and worsens environmental degradation.<\/li>\n<\/ol>\n

          Measures needed to address the heat crisis<\/strong><\/h2>\n

          Structural and architectural measures<\/strong><\/p>\n

            \n
          1. Buildings should adopt cool roofs, reflective coatings, and high-albedo materials to reduce heat absorption.<\/li>\n
          2. Passive cooling techniques such as shading, cross-ventilation, and insulation must be promoted.<\/li>\n
          3. Urban design should reintroduce courtyards, shaded pathways, and ventilation corridors.<\/li>\n
          4. Energy-efficient appliances and district cooling systems should be encouraged to reduce heat discharge.<\/li>\n<\/ol>\n

            Urban planning measures<\/strong><\/h2>\n
              \n
            1. Urban planning should preserve airflow through proper street orientation and ventilation corridors.<\/li>\n
            2. Expansion of urban forests, parks, wetlands, and water bodies is necessary for natural cooling.<\/li>\n
            3. Sustainable public transport and electric mobility should be promoted to reduce vehicular heat emissions.<\/li>\n
            4. Green and blue infrastructure should be treated as essential cooling systems in city planning.<\/li>\n<\/ol>\n

              Social protection measures<\/strong><\/h2>\n
                \n
              1. Affordable housing upgrades should be undertaken to improve thermal comfort for vulnerable groups.<\/li>\n
              2. Subsidised cooling facilities and community cooling centres should be developed during heatwaves.<\/li>\n
              3. Public awareness and heat action plans should be strengthened to protect urban populations.<\/li>\n<\/ol>\n

                Conclusion:<\/strong> Delhi\u2019s heat crisis is not only a climatic issue but also a structural and planning failure. A combination of climate-sensitive urban planning, sustainable infrastructure, ecological restoration, and social protection measures is essential to make the city resilient against extreme heat.<\/p>\n

                Question: <\/strong>What structural and urban planning measures are required to address Delhi\u2019s growing heat crisis? Discuss the economic and ecological impacts of urban heat accumulation.<\/p>\n
