As the majority of people living in cities around the world continues to grow, the challenges connected with life in densely populated urban areas are growing as well. One of the most prominent environmental features of urbanization is the tendency of temperatures in cities to gradually rise in comparison to their rural surroundings, in a localized climatic phenomenon known as the Urban Heat Island (UHI) effect. Especially during periods of heat stress in warm-weather cities, the UHI may have a debilitating effect on the health and activity of the urban population. Urban green infrastructure in general, and urban trees and forests in particular, hold an unmatched potential as a means for mitigating the UHI effect and enhancing the thermal comfort of people in cities.

Urban Heat Island (UHI): A phenomenon characterized by higher temperatures within a built-up urban area as compared with its rural surroundings, attributed to the modification of land surfaces and human activities within...
