Bhubaneswar: Urban heat island effect studied in a growing city

Urbanisation of Bhubaneswar, a tier-2 city in Odisha, India, has been rapid at 83% in the last 15 years (2000-2014) and this has led to about 89% decrease in dense vegetation and about 2% decrease in water bodies. This has led to about 1.8 degree C warming of the city compared with surrounding non-urban areas … Continue reading Bhubaneswar: Urban heat island effect studied in a growing city

Some Indian cities cooler than surrounding areas during summer days

More than 60% of the total 89 urban areas are 1-5 degree C cooler than their surrounding non-urban areas during April and 70% of cities are cooler in May. Between February and May, most of the 89 Indian cities that are to be developed as Smart Cities have been found to be 1-5 degree C … Continue reading Some Indian cities cooler than surrounding areas during summer days
