Understanding The Heat Island Effect: Causes, Impacts, and Solutions
The Heat Island Effect refers to the phenomenon in which urban and metropolitan areas experience significantly higher temperatures compared to their rural surroundings. This increase in ambient temperature occurs due to the rampant installation of paved and built-up surfaces such as roads, sidewalks, and buildings, all of which have low reflectivity and high heat retention rates.
Why Does the Heat Island Effect Occur?
The primary driver of the Heat Island Effect is urbanization. Contributing factors include:
- Absorption and Retention: Concrete and asphalt surfaces absorb sunlight and retain heat, releasing it throughout the day and night.
- Reduced Vegetation: Trees and plants provide natural cooling through shading and transpiration. Urban areas with fewer green spaces lack this cooling effect.
- Human Activities: Car engines, air conditioners, and industrial activities generate additional heat.
- Building Geometry: Structures trap heat within narrow streets, reducing airflow and creating
