Many nations have achieved success in this field since the trend of sustainable development and its applications in urban development (sustainable cities, green cities, etc.) emerged. However, other countries have not been able to achieve the same results because of various challenges and obstacles. With the goal of creating a set of broad frameworks that allow these nations to achieve sustainability in their cities, this study aims to identify the most significant barriers and difficulties that these nations face in this regard (sustainable cities). Urban sustainability in developing countries is a critical and complex issue that arises from the rapid urbanization and population growth experienced by many cities in these regions. The current state of urban sustainability in developing countries is characterized by various challenges, including inadequate infrastructure, limited access to basic services, environmental degradation, and social inequality. Developing country cities are facing a myriad of challenges and issues that hinder their progress towards sustainable development. The aim of this study is to identify and analyze these challenges, with a specific focus on their impact on the environment, society, and economy. The complexities involved in achieving sustainability in these urban settings necessitate a comprehensive understanding of the interconnected factors at play. This research seeks to contribute valuable insights to policymakers, urban planners, and stakeholders, guiding the formulation of targeted strategies for sustainable development in developing country cities. The findings will also serve as a foundation for future research and interventions aimed at fostering sustainability in urban environments.
