Upgrading informal areas through sustainable urban development principles

Abstract

Informal areas are considered one of the biggest urban problems worldwide; it was estimated in 2018 that 29% of the world’s urban population lived in informal areas (The world bank, Population living in slums, 2022). This research aimed to identify a set of criteria and principles that are the basis for sustainable development in informal areas to achieve a better quality of life for the community. After conducting a literature review of the sustainable development principles, indices, and sustainable development interventions within informal areas, the research links them to set informal areas’ sustainable development principles. Then, by relying on the experts’ questionnaires and their analysis through SPSS, the researchers utilized the experts’ input to define each principle’s relative weight. Additionally, the research applied the extracted principles to the Boulaq El Dakrour case study to assess the sustainability of previous developments undertaken in the area with community participation.
