The topic of social sustainability and livability in urban environments is of paramount importance as cities continue to expand and urbanization rates soar. In hot and arid regions like The Pearl, the distinctive climate and cultural factors present challenges in creating socially sustainable public spaces. Existing literature has predominantly focused on the indoor environment, leaving a significant gap in understanding outdoor walkability in these regions. This research study strives to bridge this gap by taking a closer look at outdoor walkability within the context of The Pearl, with an exclusive focus on its waterfront promenade. Additionally, we aim to contribute valuable insights into how the design and planning of outdoor public spaces can enhance social sustainability and livability in hot and arid climates. This study incorporates qualitative and quantitative data collection and analysis using a mixed-methods approach. Through this approach, the study investigates the physical characteristics, climate, cultural factors, and social activities associated with The Pearl's waterfront promenade. The investigation reveals that The Pearl possesses numerous physical and social attributes that enhance its walkability and livability. Nonetheless, the study also identifies several challenges that necessitate attention to fully unlock the potential of the outdoor environment in augmenting social sustainability. The findings of this study hold implications for informing the planning and design of outdoor spaces in other hot and arid regions, facilitating the enhancement of livability and sustainability in such environments.
