Urban Heat Action Plans in India: Coverage, Responsibilities and Implementation Gaps

Why in News?

A July 20, 2026 reply by the Ministry of Housing and Urban Affairs stated that Heat Action Plans have been prepared by 23 States, 195 districts and 64 cities in India.

• The coverage numbers are three reported administrative categories: 23 States, 195 districts and 64 cities. They should not be read as a single count of mutually exclusive plans because city and district jurisdictions can overlap.
• The NDMA’s 2019 national guidelines ask cities to assess vulnerability, identify factors driving urban heat islands and include suitable mitigation measures in their Heat Action Plans.
• The NDMA advisory on informal workers asks States and Union Territories to include street vendors and outdoor workers through shaded vending areas, drinking-water access, cooling centres, flexible working hours and timely heat alerts.
• MoHUA has linked urban heat mitigation with green and blue infrastructure, cool roofs, passive cooling, water-sensitive planning and climate-responsive urban design.
• Under AMRUT 2.0, a strategic pilot is assessing heat drivers and priority vulnerable areas in 12 cities and preparing city-specific recommendations.

• A Heat Action Plan is not only a weather-warning document. It is an inter-departmental operating plan for forecasts, public communication, health-system readiness, protection of exposed groups and longer-term risk reduction.
• The central governance question is whether formal coverage becomes ward-level delivery: shaded public space, water, hospital protocols, worker safeguards, cooler housing and measurable reductions in illness and death.
• Urban heat is an equity issue. People in poorly ventilated housing and those who cannot avoid outdoor work face greater exposure while often having the least access to cooling.

Prelims Relevance

• Heat Action Plan: a locally adapted plan combining early warning, preparedness, response and heat-risk mitigation.
• National Disaster Management Authority: established under the Disaster Management Act, 2005; it issues national guidance and advisories for disaster-risk management.
• India Meteorological Department: supplies forecasts, warnings and meteorological inputs used by local authorities to trigger heat-response actions.
• Twelfth Schedule: lists municipal functions under Article 243W; urban planning, land-use regulation, water supply, public health and urban forestry are relevant to heat resilience.
• Urban Heat Island: a condition in which built-up areas remain warmer than surrounding areas because of heat-absorbing materials, reduced vegetation, waste heat and altered air flow.
• India Cooling Action Plan: provides an integrated approach to sustainable cooling and thermal comfort while reducing cooling demand and improving efficiency.

Background and Context

What a Heat Action Plan Must Do

A credible HAP links an official forecast to pre-agreed local action before, during and after dangerous heat.

• The plan begins with a heat-risk and vulnerability assessment. It should identify exposed wards, dense built-up surfaces, low-green-cover areas, poorly ventilated settlements, high-risk occupations and people with health or mobility constraints.
• It defines heat-alert thresholds and communication chains so IMD information reaches departments, hospitals, schools, employers, markets and the public in time for preventive action.
• It assigns tasks for health preparedness: training staff, recognising heat illness, ensuring emergency cooling and supplies, preparing ambulances and monitoring cases and deaths.
• It provides for public protection through drinking water, shade, cooling spaces, modified school or work schedules, outreach in accessible languages and checks on high-exposure sites.
• A mature plan also contains long-term mitigation, such as cool roofs, tree canopy, shaded mobility routes, water-sensitive design, better building envelopes and preservation of water bodies.

Institutional Responsibilities from National Guidance to Ward Delivery

Heat governance is decentralised, but its institutions do not have interchangeable roles.

• The NDMA supplies national guidelines, advisories and a common disaster-risk framework. Its guidance supports State and local plans, but it does not replace local vulnerability assessment or city implementation.
• The IMD provides seasonal, extended-range and short-range forecasts, heatwave warnings and meteorological information. Local agencies use these inputs to activate response measures.
• Under the constitutional scheme and the Twelfth Schedule, urban planning is primarily a State and municipal domain. States provide legal, policy and financial backing; ULBs and urban development authorities translate it into land-use, building, water.
• District disaster-management authorities coordinate line departments across urban and peri-urban areas, align emergency response and ensure that warnings reach local institutions.
• Municipal health teams, public-health departments and hospitals handle surveillance, clinical preparedness and community outreach; labour, market, transport, water, education and power agencies act on sector-specific exposure.

Urban Heat Island, Housing and the Built Environment

Urban form can amplify heat exposure even when two places receive the same regional weather warning.

• Dark roofs and paving absorb solar radiation; dense construction can restrict air flow; loss of vegetation reduces shade and evapotranspiration; vehicles, industry and air conditioners add anthropogenic heat.
• Housing quality determines indoor exposure. A household may remain dangerously hot after sunset when a concrete or metal roof stores daytime heat and the dwelling lacks cross-ventilation, insulation or safe night-time cooling.
• MoHUA’s cooling guidance follows an avoid-shift-improve logic: reduce cooling demand through climate-responsive design, meet remaining demand with lower-carbon systems, and improve the efficiency of conventional cooling.
• Cool-roof options include reflective coatings, membranes, high-albedo tiles and context-appropriate alternatives. The choice must account for roof type, maintenance, water needs, affordability and local skills rather than impose one technology everywhere.
• For low-income households, cooler roofs and better ventilation are not merely energy measures. They can improve sleep, health and home-based work conditions while lowering dependence on unaffordable mechanical cooling.

Informal Workers and the Unequal Geography of Exposure

Heat risk is shaped by the ability to stop work, find shade, drink safe water and recover in a cool home.

• Street vendors, construction workers, sanitation workers, delivery workers, transport workers and other outdoor earners face direct solar exposure and physical exertion, often without secure rest breaks or nearby water.
• The NDMA advisory calls for shaded vending zones, hydration facilities, cooling centres, flexible working hours and timely alerts for street vendors and other outdoor workers.
• A gender-sensitive plan must examine differential access to water, sanitation, safe rest space, health care and income security. Pregnant workers and people with caregiving responsibilities can face compounded heat stress.
• Changing work hours without wage protection can shift risk rather than reduce it. Local plans should pair schedules and breaks with income-sensitive enforcement, employer duties and accessible grievance channels.
• Worker protection must extend beyond registered establishments. ULB databases, vendor associations, contractors, resident groups and community health networks can help reach people in informal and mobile occupations.

Way Forward

Turn Every Plan into a Funded Operating Protocol

• Publish a department-wise trigger-action matrix for each warning level, with named nodal officers, backup contacts, deadlines and proof-of-action fields.
• Create a dedicated budget line or clearly tagged expenditure for heat preparedness and mitigation, linked to annual municipal and district planning.
• Run pre-season simulation exercises for hospitals, schools, markets, water teams and emergency services; disclose gaps and corrective action.

Conclusion

• India’s spread of Heat Action Plans across 23 States, 195 districts and 64 cities is an important institutional base.
• The strongest heat policy joins early warning with public health, worker protection, cooler housing and climate-responsive urban design.

UPSC Practice Questions

Prelims MCQ 1

With reference to urban heat governance in India, consider the following statements:

1. Urban planning is among the municipal functions associated with the Twelfth Schedule of the Constitution.
2. The India Meteorological Department provides forecast and warning inputs used in Heat Action Plans.
3. The National Disaster Management Authority directly performs all municipal land-use planning in heat-prone cities.

How many of the above statements are correct?

(a) Only one (b) Only two (c) All three (d) None

Answer: (b) Only two

Explanation:

Statements 1 and 2 are correct. Urban planning is a municipal function associated with the Twelfth Schedule, and IMD supplies meteorological forecasts and warnings. NDMA issues guidelines and advisories; it does not take over municipal land-use planning.

Prelims MCQ 2

Which one of the following best describes an urban heat-island mitigation measure?

(a) Replacing permeable ground with dark asphalt (b) Removing tree canopy to increase road width (c) Combining cool roofs, shaded streets and restored water bodies (d) Restricting heat alerts to hospital administrators

Answer: (c) Combining cool roofs, shaded streets and restored water bodies

Explanation:

Cool roofs reduce solar heat gain, shade lowers direct exposure, and water bodies can support evaporative cooling and local climate resilience. The other choices increase heat absorption or restrict protective communication.
