Urban Resilience to Environmental Displacement: Sustainable Design Strategies in Samarra and Najaf

This research investigates the critical role of urban resilience as a strategic framework to mitigate climate-induced environmental displacement in hot-arid regions, specifically focusing on the historical Iraqi cities of Samarra and Najaf. As global temperatures rise, these cities face intensifying thermal stress and desertification, acting as primary ``push factors'' for involuntary migration. The objective of this study is to evaluate the efficacy of sustainable urban design and traditional planning morphologies in enhancing the adaptive capacity of these urban centers. The methodology employs a Variable-based Digital Spatial Analysis utilizing Landsat 8 TIRS and Sentinel-2 satellite imagery. Through advanced geospatial processing, original maps for Land Surface Temperature (LST) and Normalized Difference Vegetation Index (NDVI) were generated to quantify the correlation between urban fabric density and thermal performance. The findings reveal a significant thermal disparity between traditional and modern urban layouts. Traditional compact tissues, characterized by narrow winding streets and shaded internal courtyards, demonstrated superior microclimate regulation, reducing surface temperatures by up to 10.5 °C compared to modern open-plan residential blocks. The study highlights that the absence of integrated green infrastructure and high-albedo materials in new developments exacerbates the Urban Heat Island (UHI) effect, directly threatening inhabitant stability. The research concludes that achieving long-term urban resilience requires a hybrid planning approach that integrates the socio-environmental wisdom of ancient metropolis design with modern sustainable technologies, such as nature-based solutions and passive cooling strategies. This integration is essential not only for thermal comfort but as a fundamental necessity for the socio-economic preservation and climate adaptation of Samarra and Najaf, ensuring these cities remain habitable and secure for future generations against the escalating climate crisis.
