The concept of sustainable urban development has evolved significantly over the past decade, moving beyond mere environmental concerns to encompass social equity and economic viability. Recent studies indicate that cities adopting integrated green infrastructure, such as permeable pavements and urban forests, not only reduce flood risks but also lower ambient temperatures, thereby mitigating the urban heat island effect. However, critics argue that such initiatives often prioritize affluent neighborhoods, exacerbating spatial inequality. A longitudinal analysis of 12 European cities revealed that participatory planning processes, where residents directly influence project selection, tend to produce more equitable outcomes. Nevertheless, these processes require substantial administrative capacity and political will, which many developing regions lack. Consequently, while the technical solutions are well-documented, their successful implementation hinges on governance structures that can balance diverse stakeholder interests, a challenge that remains unresolved in many contexts.
