Large cities are increasingly affected by the phenomenon of “Urban Heat Islands” (UHI), particularly during the dry summer months. This phenomenon especially affects the MENA region, which is the driest in the world and therefore the most vulnerable to climate change. The aim of this work is to identify UHI that affect the quality of urban life. The study was conducted during 2022 in a densely populated area of the Belouizdad (Belcourt) municipality (Algiers, Algeria). The study area is particularly dominated by the residential urbanization that represent about 75%. The plant element account for only 14 per cent of the study area.. To identify the urban heat islands (UHI), we used a simple, easy and reproducible empirical method developed by NEPSEN-E6. This approach consists of attributing a UHI score to each element of the ground surface: plant, buildings, parks and roads. The predominance of UHIs, underscore the importance of the mineral element (over 70%), creating a large zone of UHIs whows the imbalance between mineral and plant elements. The projection map shows these UHIs that can be reduced if mitigation measures are taken into account in the municipality's strategy (such as increasing green space) to address the effects of climate change.
