Jitendra drives his autorickshaw every day in the scorching heat of Delhi’s heatwave. He travels from his locality in Sangam Vihar, Asia’s largest unauthorised colony, to neighbouring Sainik Farm, an affluent and planned locality in South Delhi.
“When I drive to areas like Sainik Farm, which have more trees and open spaces, I get some relief. But congested areas like Sangam Vihar are very hot,” said Jitendra.
Studies have shown that there is a correlation between temperatures and the way a city is built and developed. Areas that are more concretised, congested, and densely populated experience higher temperatures.
