What is the common examiner trap about Environment in UPSC exams?

They may ask which disaster is 'not' covered under NDRF, using heatwave as the correct answer. They may also swap the IMD heatwave thresholds for different regions (plains vs. coastal vs. hilly) or confuse the Kigali Amendment phase-down percentages and years.

What should UPSC aspirants remember about Environment for Prelims?

1. Target this Data: 380 million workers in heat-exposed jobs (World Bank 2022). 2. Target this Nodal Body: National Disaster Management Authority (NDMA) for Heat Action Plan guidelines. 3. Target this Legal Point: Heatwave is NOT included in the list of 12 disasters eligible for NDRF/SDRF funds.

Heatwave Thresholds, 380M Exposed Workers & ICAP: India's Climate Action for 75% Workforce

Q: Which national authority is primarily responsible for issuing the guidelines for the preparation of Heat Action Plans (HAPs) in India?

National Disaster Management Authority (NDMA), The article states that the NDMA issued 'Guidelines for Preparation of Action Plan – Prevention and Management of Heat Wave' in 2016, which were revised in 2017 and 2019. The NDMA collaborates with states to implement HAPs.

Q: Consider the following statements regarding heatwaves in India: 1. For coastal regions, the India Meteorological Department (IMD) declares a heatwave when the maximum temperature reaches or exceeds 37°C. 2. Heatwaves are included in the list of 12 disasters eligible for financial assistance from the National Disaster Response Fund (NDRF). 3. The India Cooling Action Plan (ICAP), launched in 2019, is aligned with India's commitments under the Kigali Amendment to phase down Hydrofluorocarbons (HFCs). Which of the statements given above is/are correct?

Both 1 and 3, Statement 1 is correct as per IMD thresholds mentioned in the article. Statement 2 is incorrect because the article explicitly states heatwave is NOT among the 12 disasters eligible for NDRF/SDRF support. Statement 3 is correct as the article links ICAP to the Kigali Amendment commitments for HFC phase-down.

Q: According to a 2022 World Bank report cited in the article, approximately how many workers in India are engaged in heat-exposed work?

380 million, The article directly states: "According to a 2022 report by the World Bank, about 75 per cent of India’s workforce (~ 380 million people) is involved in heat-exposed work." This is a key data point for understanding the scale of vulnerability.

Q: What is identified as a primary structural weakness in India's policy response to heatwaves, as per the article?

Exclusion of heatwaves from the list of disasters eligible for NDRF/SDRF funds, The article highlights that only 12 disasters qualify for NDRF/SDRF support and heatwave is not one of them, leaving states severely underfunded for response. This is cited as a major structural gap, unlike the other options which are factually incorrect based on the article's content.

What This Article Covers

1.Heatwaves, defined by IMD thresholds (40°C for plains, 37°C for coasts, 30°C for hills), are arriving earlier and intensifying due to climate change and urban heat island effects.

2.India's policy response includes National Disaster Management Authority (NDMA) Heat Action Plans (HAPs) in 23 states and the India Cooling Action Plan (ICAP) 2019, aiming for a phased HFC reduction under the Kigali Amendment.

3.Critical gaps remain: heatwaves are not a notified disaster eligible for NDRF/SDRF funds, HAPs lack local vulnerability assessments, and cities prioritize short-term emergency measures over long-term solutions like green spaces.

The Big Picture

Prelims · HighMains · High

India faces an escalating heatwave crisis, exposing 380 million workers (75% of the workforce) to severe risks. The government's response includes Heat Action Plans (HAPs) and the India Cooling Action Plan (ICAP), but structural gaps like exclusion from disaster funds and urban heat islands pose major challenges for climate resilience.

News Snapshot

🌡️

Defining a Heatwave

IMD declares a heatwave based on regional thresholds (40°C plains, 37°C coast, 30°C hills) and a temperature departure of 4.5°C–6.4°C from normal.

🏙️

Urban Heat Island Effect

Cities like Mumbai record 15 extra warm nights per summer due to dense construction, waste heat, and reduced green spaces, worsening heat stress.

📜

Policy Framework Gaps

Heatwaves are not a notified disaster under NDRF/SDRF, limiting funds, while Heat Action Plans often lack local vulnerability data and long-term solutions.

Detailed Analysis & Strategic Depth

Context / Background

Heatwaves, historically peaking in May-June, are now occurring earlier in April due to anthropogenic climate change, as confirmed by the IPCC AR6 report. India's tropical geography, high population density, and large outdoor workforce (~380 million) make it uniquely vulnerable. The National Disaster Management Authority (NDMA) first issued Heat Action Plan guidelines in 2016, revised in 2017 and 2019.

Core Analysis & Implications

The crisis is multi-faceted: climatic (hot dry air, no cloud cover), anthropogenic (global warming, GHG emissions), and urban (Heat Island Effect). The India Cooling Action Plan (ICAP) 2019 addresses rising cooling demand but faces the challenge of low AC penetration (<10% households). A major structural flaw is the exclusion of heatwaves from the list of 12 disasters eligible for NDRF/SDRF funding, crippling state response capacity. Mortality data is likely under-reported.

Future Outlook / Way Forward

Experts advocate for notifying heatwaves as a disaster to unlock funds, developing local heat vulnerability maps instead of uniform thresholds, and mandating green infrastructure (green roofs, reflective pavements) in urban planning. Ensuring equitable access to cooling for vulnerable populations and meeting India's Kigali Amendment HFC phase-down targets (10% by 2032, 85% by 2047) are critical long-term priorities.
