Urban Heat Island
An Urban Heat Island (UHI) is a phenomenon where urban areas experience higher temperatures than their rural surroundings. This temperature difference is primarily due to human activities, such as the extensive use of concrete, asphalt, and buildings that absorb and retain heat. Additionally, reduced vegetation in cities limits natural cooling processes.
The UHI effect can lead to increased energy consumption, elevated emissions of air pollutants, and health risks for residents. Strategies to mitigate UHI include increasing green spaces, using reflective materials for buildings, and implementing urban planning practices that promote natural cooling, such as planting trees and creating parks.
