The concept of sustainable urban development has evolved significantly over the past decade, shifting from a purely environmental focus to a more integrative approach that encompasses social equity and economic viability. Recent studies suggest that cities adopting green infrastructure, such as permeable pavements and urban forests, not only mitigate flooding and heat islands but also enhance mental well-being among residents. However, critics argue that without inclusive governance, these initiatives may inadvertently displace low-income communities, a phenomenon known as 'green gentrification'. Therefore, effective policies must balance ecological goals with affordable housing and community engagement to ensure that sustainability benefits are equitably distributed.
