The research focuses on developing an intervention strategy for unsafe urban areas in Qalyubia Governorate and examines how the evaluation policy of ISDF affects the type of interventions required to improve physical conditions and the lives of inhabitants, while also highlighting shortcomings of the policy. In 2015, ISDF launched a project called "Egypt without Shanties," and our institution, the Faculty of Engineering at Shoubra, was tasked with creating a report on the status quo of unsafe areas in Qalyubia governorate and determining the appropriate intervention method for each area. This led to the categorization of unsafe areas according to their degree of risk, which prioritized the urgency of interventions. Four areas were selected for research: Al Zaraieb, El-Bakry, Hayd Ganeb Alra'y, and Al-Jami' Street. Results showed significant differences between the information provided by ISDF on the predefined unsafe areas and the status quo observed by field visits and surveys in terms of area size. The research also discusses the government's implementation of proposed intervention methods and criticizes ISDF's policy for giving more consideration to factors of media interest and small size, downgrading the harmful impact of the area on the surrounding environment, and neglecting critical factors such as health and education, which are essential to the study area.
