Urban resilience is recently a prominent issue due to rapid urbanization and increasing challenges and stressors affecting cities. Assessment of urban resilience is an essential step in enhancing resilience performance since regular assessment informs resilience action plans, determines areas of deficiencies, and provides spatial and temporal comparisons. However, resilience assessment is a complex process that requires intensive data and resources due to the multi-dimensional and dynamic nature of resilience, and the imprecision of resilience data. In this context, the research aims to develop The Resilience Performance Index (RPI), through setting a conceptual framework, defining relevant resilience indicators, and finally modelling resilience performance using The Fuzzy Logic Approach, aiming to combine resilience analysis with artificial intelligence (AI) tools and dynamic modelling methods. The RPI assesses both qualitative and quantitative resilience indicators obtained through records, census data or structured questionnaires. Indicators’ values are modelled through a designed fuzzy logic system to obtain the resilience performance score. The developed index is applied on New Damietta city to inform resilience action plans in the Nile Delta region. The RPI addresses the complexity of resilience assessment and ambiguity of resilience data through an easy applicable, user friendly approach without the need for complex mathematical and statistical methods.

This study examines the use of landscape design to replace slums in residential areas. The research is based on a descriptive and analytical approach, drawing information from previous studies that have addressed landscape design to achieve sustainability in residential areas. The study aims to develop a comprehensive assessment of the use of landscape elements in an environmentally sustainable manner, focusing on site coordination, water, energy, soil, vegetation, maintenance operations, and materials. The research also considers the impact of landscape design on human well-being. The study was applied to the Rawdat Al-Sayeda Zeinab area in Cairo, and the results were compared with planned landscape designs to identify differences and necessary modifications. The study provides guidelines for using landscape design to achieve sustainability in residential areas and sets a direction for future research.
