Model of social sustainability for Dhaka city, Bangladesh

The expansion and development of urban areas require a strategic priority of social sustainability to protect their inhabitants' quality of life and well-being. However, social sustainability in urban areas, particularly in developing regions, becomes more apparent due to the social problems caused by rapid urbanization. The main objective of this study is to propose a model of social sustainability for socially sustainable cities in developing regions. To accomplish this objective, a quantitative research strategy was used to gather responses from residents of Dhaka city via a structured questionnaire survey; Dhaka served as a representative city from a developing region. This study used a multistage sampling technique to select 564 residents of Dhaka city. The results showed that social sustainability significantly influenced socially sustainable urban development in Dhaka, determining 38 indicators under 11 social sustainability themes using exploratory and confirmatory factor analysis utilizing structural equation modeling. The implication of this model serves as a guiding framework intended to assist governmental bodies, policymakers, and urban planners in navigating the path toward achieving sustainable cities. Likewise, the proposed model provides policy implications for enacting and revising urban sector policies in developing regions, considering the fundamental themes of social sustainability. Eventually, this study contributes to implementing Sustainable Cities and Communities (SDG 11) in the 2030 Agenda for Sustainable Development, bridging the gap between urbanization and sustainable urban societies. Also, this model is a valuable tool for promoting socially sustainable urban development in developing regions.
