Body · points and prose

SUN (pointing arrows down)
arrows pointing down from H.P.
Heat dome effect (arch showing trapped heat)
2. Anthropogenic factors such as climate change due to carbon emission traps heat
3. Urban Heat island due to asphalt construction
Effects of heatwaves
- It causes an increase in maximum temperature of a region, thus prolonged heat
Plain (above 40°C) <---> Hilly region (above 30°C)
- Loss of life due to heat stroke.
- Threat to livestock.
- Failure of crops due to extreme heat conditions → food insecurity
- Increased pressure on water leading to decrease in water table.
Therefore, various policies are adopted in India for effective management of
extreme risk of heat :
Role of IMD in early warning system
Promoting Green city through "Nagar Vans"
Ensuring "whole of society" approach
Mitigation (Biophilic design) -> Preparedness (Ensuring climate resilient lifestyle) -> Response (utilising "virtual meet" to escape going out)
- Proactive role of governance in harnessing digital technology

The increased frequency of heatwaves demand categorisation as "disaster" in India
