Urban Heat Island Effect

India is facing intense heatwave conditions, and rising urban temperatures are adding to the concern.

The Urban Heat Island (UHI) effect is making cities hotter than nearby rural areas by 1.7°C to 4°C.

This happens because concrete and asphalt absorb and store heat during the day and release it slowly at night.

Lack of greenery reduces natural cooling, while dark surfaces trap more heat. As a result, cities face higher health risks, increased power consumption, and worsening air quality.

In 2026, experts are focusing on solutions like urban greening, cool roofs, and better materials to reduce heat. Smarter city planning is now crucial to make urban areas more livable.
