🔆 Urban Heat Islands

✅ Urban Heat Islands (UHI) are urbanized areas that experience higher temperatures than outlying areas. 

✅ Structures such as buildings, roads, and other infrastructure absorb and re-emit the sun’s heat more than natural landscapes such as forests and water bodies. 

✅ Urban areas, where these structures are highly concentrated and greenery is limited,become “islands” of higher temperatures relative to outlying areas. 

✅ It increases the demand for energy, leads to increased greenhouse gases emissions, discomforts human health and even affects the health of flora and fauna.

▪️The major factors responsible for UHI 

✅ Anthropogenic heat  

discharges

✅ Absorption of heat

✅ Urban geometry

✅ Greenhouse effect

✅Lack of vegetation

 

▪️Measures that can be taken to countering UHIs

✅ Promoting natural vegetation

✅ Use of appropriate surface material

✅ Use of white pavement instead of Asphalt

✅Providing appropriate landscape
