The concept of sustainable urban development has evolved significantly over the past decade, shifting from a focus on mere environmental protection to a more integrated approach that encompasses economic viability and social equity. Recent studies indicate that cities adopting green infrastructure, such as permeable pavements and urban forests, not only mitigate flooding and heat islands but also enhance property values and public health. However, critics argue that without inclusive governance, these initiatives can lead to gentrification, displacing low-income residents. Thus, effective sustainable planning requires balancing ecological goals with affordable housing policies and community engagement, ensuring that the benefits of greening are equitably distributed across all socioeconomic groups.
