Delhi Heat Action Plan Launched to Mitigate Urban Heatwaves
Source:The Hindu ↗

Why It Matters
Demonstrates proactive, decentralized disaster management in response to climate change. The integration of structural measures (cool roofs, cooling centres), early warning systems (SMS alerts), and community resilience ('aapda mitra' volunteers) offers a model for urban heat adaptation relevant to GS3 (Disaster Management) and GS1 (Urbanization/Heat Islands).
Summary
Delhi Chief Minister Rekha Gupta announced the Delhi Heat Action Plan 2025 to mitigate the severe impacts of urban heatwaves, which she termed a "deadly crisis." The multifaceted strategy encompasses public health preparedness, such as dedicated heatwave wards in hospitals, alongside infrastructural adaptations like cool roof technologies, shaded bus stops, and cooling centres in vulnerable neighborhoods. Crucially, the plan relies on 1,800 Central government-provided 'aapda mitra' disaster volunteers for frontline implementation, with a specific focus on protecting high-risk demographics including outdoor workers, the elderly, and the economically weaker sections.
Key Points
- Delhi Chief Minister Rekha Gupta launched the Delhi Heat Action Plan 2025, describing heatwaves as a deadly crisis rather than just a weather condition.
- The plan includes the installation of 3,000 water coolers, sending heatwave alerts via SMS, and establishing dedicated heatwave wards with ICU beds in government hospitals.
- Urban mitigation measures encompass implementing cool roof technology in government buildings, providing shaded bus stops, and establishing cooling centres in slums and low-income neighborhoods.
- The implementation will be supported by 1,800 "aapda mitra" (disaster volunteers) assigned by the Central government to act as frontline responders.
- Vulnerable groups such as children, the elderly, outdoor workers, women, the economically weaker sections, disabled persons, and chronic illness patients will be prioritized.
Important Terms
Delhi Heat Action Plan 2025
A comprehensive policy launched by the Delhi government to mitigate extreme heat risks. It integrates early warning systems, public health infrastructure (heatwave wards), and urban cooling measures (cool roofs) to protect vulnerable demographics.
UPSC context
GS Paper 3: Disaster Management and Environment; tests understanding of state-level climate adaptation and urban resilience strategies.
Aapda Mitra
A Central Sector Scheme implemented by the National Disaster Management Authority (NDMA) to train community volunteers as first responders. They provide frontline relief and rescue during disasters like floods or heatwaves.
UPSC context
GS Paper 3: Disaster Management; tests knowledge of community-based disaster risk reduction (CBDRR) and grassroots crisis response frameworks.
Urban Heat Island (UHI) Effect
A phenomenon where urban areas experience significantly higher temperatures than surrounding rural areas. This is caused by heat-absorbing surfaces like concrete, lack of vegetation, and waste heat from human activity.
UPSC context
GS Paper 1: Geography (Urbanization) and GS Paper 3: Environment; tests understanding of human-induced microclimate changes.
Heatwave
A period of abnormally high temperatures, specifically defined by the IMD based on departures from normal limits. It poses severe health risks and is classified as a disaster in many states.
UPSC context
GS Paper 1: Physical Geography and GS Paper 3: Disaster Management; tests criteria for weather extremes and mitigation policies.
Cool Roof Technology
An adaptation strategy using high-reflectance materials or coatings to minimize solar heat absorption in buildings. This reduces indoor temperatures, energy consumption, and the overall urban heat island effect.
UPSC context
GS Paper 3: Environment and Infrastructure; tests knowledge of sustainable urban planning and passive cooling techniques.
Prelims Trap
Heatwaves are a centrally notified disaster under the Disaster Management Act, 2005.
While the NDMA issues guidelines for Heat Action Plans, heatwaves are NOT a centrally notified disaster under the Disaster Management Act for standard NDRF/SDRF funding.
Static Concepts Connected
What are the IMD criteria for declaring a heatwave in India?
- Plains threshold: The maximum temperature of a station reaches at least 40°C.
- Coastal & Hilly: The maximum temperature reaches at least 37°C in coastal regions and 30°C in hilly regions.
- Departure condition: The temperature must be 4.5°C to 6.4°C above the region's normal temperature (Severe if >6.4°C).
What is the 'Aapda Mitra' scheme?
- Central Sector Scheme: A Central Sector Scheme under the National Disaster Management Authority (NDMA).
- Core Objective: Aims to train 100,000 community volunteers in disaster response across 350 most flood-prone/disaster-prone districts.
- Volunteer Support: Volunteers are equipped with standard first responder kits and life insurance during disaster duties.
Cross-Topic Patterns
Aapda Mitra + Sendai Framework
Deploying 'Aapda Mitra' volunteers operationalizes the Sendai Framework's emphasis on Community-Based Disaster Risk Reduction (CBDRR), empowering locals as first responders.
Urban Heat Islands + Building Codes
Mitigation strategies like 'cool roofs' directly link urban disaster management with the Energy Conservation Building Code (ECBC) and sustainable urbanization efforts.
Expect a 2026 Prelims question mixing IMD heatwave criteria, the UHI effect, and whether heatwaves are officially notified disasters.
