Kolkata's Urban Heat Islands

A study conducted by Calcutta University and Vidyasagar University jointly measures the effect of heat in the central areas of the city. The total amount of UHI growth has been 44.6sqkm over the last three decades, with an urban expansion of 28.7sqkm.

Studies have shown that UHIs affect plant's growth patterns, rainfall patterns by increasing rainfall downwind of cities, and the formation of clouds and fog. Practices of green roofing and waterproofing are required to cover concrete buildings with green plants.

“The only solution to the problem is to increase vegetation,We are in a vicious cycle of the climate crisis. The city’s green cover was ravaged by more frequent cyclones, induced by climate change. And, as we are losing green cover, we are becoming more susceptible to the effects of UHIs,” said climate scientist Arindam Roy .
