Urban Heat Island Effect
The Urban Heat Island (UHI) effect occurs when urban areas become significantly warmer than their rural surroundings due to human activities and land use. This happens because buildings, roads, and concrete absorb and retain heat from the sun, while vegetation, which cools the air through shading and evaporation, is often limited in cities. As a result, cities can experience higher temperatures, particularly at night. This effect can lead to increased energy consumption, elevated emissions of air pollutants, and adverse health impacts, especially during heat waves. Addressing UHI involves increasing green spaces and using reflective materials in urban planning.

The Urban Heat Island (UHI) effect refers to the phenomenon where urban areas become significantly warmer than their rural surroundings. This occurs due to factors like concrete, asphalt, and buildings absorbing and retaining heat, as well as reduced vegetation. Urban activities, such as transportation and industrial processes, also contribute to higher temperatures. As a result, cities can experience higher energy consumption for cooling, increased pollution, and health risks for residents. Understanding UHI is important for urban planning and implementing measures to mitigate its impact, such as increasing green spaces and using reflective materials.

The urban heat island effect refers to the phenomenon where urban areas, like cities, become significantly warmer than their surrounding rural areas. This is caused by human activities and structures, such as concrete buildings, asphalt roads, and fewer trees, which absorb and retain heat. Factors like increased energy use, vehicles, and industrial activities also contribute to higher temperatures. This effect can lead to increased energy consumption for cooling, poor air quality, and health issues, particularly during heatwaves. Mitigating the urban heat island effect is important for creating more sustainable and livable urban environments.
