Am sure we didn’t need a reason for planting trees, however, to drive the point home further, here are some numbers too!
An empirical study by Harini Nagendra who teaches at Azim Premji University points out that trees help to reduce heat in cities. According to her paper, trees reduced surrounding air temperatures by as much as 5.6°C and cooled off tava hot road surface temperatures by 27.5°C. The paper also shows that trees mitigate the impact of dust pollution caused by construction activities. The paper highlights that street trees have a significant impact on controlling air pollution in cities like Bengaluru as they reduce Suspended Particulate Matter (SPM) levels by as much as 75% on roads.
