Background

UPSC frequently examines the impacts of climate change, disaster management strategies, public health challenges, and the role of governance in protecting citizens from environmental hazards. This concept integrates environmental science, public health, and policy responses.

Heatwaves are periods of abnormally high temperatures, often accompanied by high humidity, which can have severe impacts on human health, leading to heatstroke, dehydration, and exacerbation of pre-existing conditions. Effective public health management during heatwaves involves a multi-faceted approach to mitigate risks and protect vulnerable populations.

Facts & tables

Health Risks
Heatwaves increase risks of dehydration, heatstroke, and impair the body's ability to regulate temperature.
Vulnerable Populations
Elderly, children, and individuals with chronic illnesses are particularly susceptible to heat-related illnesses.
Alcohol's Role
Alcohol consumption exacerbates heat-related risks by increasing urine production (dehydration) and dilating blood vessels (impaired thermoregulation).
Government Interventions
Measures include early warning systems, opening cooling centers, restricting high-risk activities (e.g., alcohol bans), and urban planning adjustments (e.g., 24/7 park access).
Evolution of French Heatwave Response
Period Key Measures
Pre-2003 Less interventionist, high mortality (e.g., ~15,000 deaths in 2003)
Post-2003 More interventionist: cooling centers, checking on vulnerable, activity restrictions (e.g., alcohol ban, parks open 24/7)

  9. Why France has banned alcohol in places with high heat

    Heatwaves pose significant public health risks, exacerbated by climate change. Governments implement measures like activity restrictions (e.g., alcohol bans), cooling centers, and urban planning adjustments (e.g., 24/7 park access) to mitigate health impacts, especially for vulnerable populations.

In a multi-ethnic district where both economic competition and historical grievances frequently led to community tensions, a flashpoint has arisen with a Government decision to allocate land for a waste management facility near a tribal hamlet, sparking protests by the tribal community, which claimed that the land was sacred and critical to their cultural identity. At the same time, urban residents and local industries supported the project, citing severe solid waste challenges and health concerns due to lack of a proper disposal site. The conflict has escalated with road blockades, social media campaigns, and allegations of police excesses.

As a responsible Government official, you are tasked with resolving the situation through mediation, ensuring a sustainable outcome that balances environmental needs, tribal rights, and urban public health.

Consider the following statements with reference to the above:

1. A successful conflict resolution process must begin with acknowledging the cultural concerns of the protesting tribal community before discussing technical alternatives.
2. The Government should move ahead with the project without delay to address urban health concerns, which outweigh the sentiments of a small group.
3. Creating a multi-stakeholder dialogue platform — including tribal leaders, environmental experts, and municipal representatives — to build mutual understanding and help de-escalate tensions.
4. Conducting an independent Environmental and Social Impact Assessment (ESIA) and sharing findings transparently with both sides to facilitate evidence-based decision-making.

Which of the statements given above would contribute to the resolution process?
