Urban Heat Islands (UHIs) have become a significant phenomenon in Indian cities, exacerbating the frequency and intensity of heat waves. Analyze the underlying factors contributing to this phenomenon and critically assess the existing mitigation strategies.
Main Body
Urban Heat Island (UHI) refer to select relatively high temperature in Urban areas as a - high temperature in Urban areas is a - which leads to multiple UHI effects.
UHI exacerbating frequency and intensity of Heat Waves
Heat Waves have doubled in last decade as per IMD
Lack of blue green infrastructure
Factors Contributing to Heat waves and UHI:
High rise Building prevent flow of air
Lack of blue green infrastructure prevents inadequate effent
Concentration of land leads to high temperature
High energy consumption due to Cooling houses AC position impact
Increased private transport use due to release of GHG which absorbs terrestrial radiation
Lack of awareness further encourage the impact
