M’sila, like other Algerian cities, faces major difficulties that result in urban deterioration compromising the quality of life. Informal urban settlements become interconnected with the city’s urban structure, requiring a strategic and effective intervention to restore these places and enhance living circumstances. Many studies have shown that informal housing is widespread and represents one of the most dominant features of urbanization in developing countries. The aim of this study is to conduct examinations of urban renewal strategies and emphasize their crucial significance in incorporating informal urban settlements into an authorized urban framework, thus supporting the advancement of sustainable urban development. GIS are utilized to conduct accurate geographical analysis in accordance with multicriteria decision analysis (MCDA) methods to methodically find and assess suggested alternatives. The methodology involved collecting and analyzing field data using advanced analytical tools to generate practical recommendations. The study concludes that urban renewal strategies integrating GIS and MCDA significantly improve the quality of life in informal settlements, particularly when prioritizing infrastructure upgrades and community participation.
