The concept of sustainable urban development has evolved significantly over the past decade. Initially focused on reducing carbon emissions through green architecture, the field now encompasses broader socio-economic factors. Researchers argue that truly sustainable cities must integrate affordable housing, public transportation, and green spaces to foster social equity. A recent study by Martinez et al. (2022) found that cities prioritizing mixed-use zoning experienced lower commute times and improved mental health among residents. However, critics point out that such policies often lead to gentrification, displacing low-income communities. Therefore, sustainable urban planning requires a delicate balance between environmental goals and social inclusion, demanding participatory approaches that involve local stakeholders in decision-making processes.
