The urban heat island effect is one of the most visible manifestations of human alteration of natural landscapes and is closely connected to the larger discourse on climate change. Cities are characterized by dense settlements, large-scale replacement of natural surfaces with concrete, asphalt, and glass, as well as intense energy consumption patterns. These changes create localized warming in urban areas compared to surrounding rural regions, a phenomenon widely known as the urban heat island. To understand its causes and mechanisms, it is essential to analyze how urban design, human activities, and energy exchanges combine to produce this effect, and subsequently, how strategies can be developed to minimize the resulting impacts on urban ecosystems in the context of climate change. The primary cause of the urban heat island effect is the alteration of land cover. In natural landscapes, vegetation, soil, and water bodies contribute to cooling through evapotranspiration and surface reflectivity. When these are replaced by asphalt, concrete, and rooftops, the surfaces absorb and retain more solar radiation during the day and release it slowly at night. The thermal properties of urban materials, which have low albedo and high heat capacity, trap heat and elevate urban temperatures. For instance, asphalt roads absorb a large proportion of solar radiation and radiate heat long after sunset, reducing nocturnal cooling that normally occurs in rural areas. A second mechanism is the lack of vegetation and green cover in urban areas. Trees and plants provide shade and reduce heat through the process of evapotranspiration, where water is released into the atmosphere, cooling the surrounding environment. Urban areas, however, often lack sufficient greenery due to land-use pressures, and this loss of natural cooling exacerbates local warming. Similarly, the replacement of wetlands, ponds, and open spaces with impermeable surfaces reduces natural cooling systems. Another important factor is anthropogenic heat release. Human activities such as transportation, industrial operations, use of air conditioners, and energy generation emit additional heat into the atmosphere.
