Behavioral research studies propose that urban open spaces contribute to enhance sociability in urban areas. The urban areas in the city of Abu Dhabi are less appealing to attract vibrant activity and social life. This study investigates the role of the built environment in the enhancement of neighborhood satisfaction and social capital in a residential neighborhood of Abu Dhabi. A total of 145 residents were surveyed for their perception, attitude, and behavior. Regression analyses to predict the role of the built environment of the open space, as well as the ethnicity of respondents, on measures of neighborhood satisfaction and social capital were performed. Spatial data and audit tools were used to assess the lack of suitable built-environment in the study area. Results indicate that improvements to the built environment can improve both the social capital and neighborhood satisfaction of the urban residents of Abu Dhabi. Implications of this study include recommendations to enhance the experience of urban spaces in arid regions like Abu Dhabi. Recommendations include adding landscape elements, providing a comfortable walking environment, adding attractive locations and destinations, and a clean and safe environment with attractive buildings or homes.Sustainability 2020, 12, 3200 2 of 16 neighborhood [12]. However, the perception of availability, use, and attractiveness of such spaces in the middle east, particularly in the capital city of the United Arab Emirates, Abu Dhabi, is limited at best.Abu Dhabi is the largest of the seven emirates in the UAE federation system. The developed land of Abu Dhabi covers 972.45 km 2 of the emirate. As of 2014, the urban population was estimated to be 1.14 million, while the rural population was 493,253, and 81% of the total population was made up of expatriates (SCAD) [13]. In 2007, the Abu Dhabi Urban Planning Council (UPC) introduced the Vision Abu Dhabi 2030. One of the vision goals introduced in the charrette was to create a livable city by developing a good open space network [14]. Although the city launched many community facilities and public realm guidelines, implementation remains slow and limited. At present, there are no specific policies and regulations to improve the public spaces in the existing residential blocks. Additionally, there is very little understanding of what type of open space is preferred by the residents, and what kind of retrofit would enhance the social capital of the neighborhood. With the World Expo 2020 to be hosted in the UAE, all emirates, including Abu Dhabi, are involved in new development and redevelopment of the urban area. Outcomes from this can help recommend appropriate design and policy approaches that can improve the livability of these urban areas and improve the social sustainability of the neighborhoods.Therefore, this study examines the relationship between the built environment (walkable open spaces) and the multi-cultural setting impact neighborhood satisfaction. This study also investigates the relationship of the built e...
