Redefining urban spaces in stormwater assessment through ecosystem management: A narrative review

Climate neutrality requires urban infrastructure overhauls, particularly in rainwater management and green space expansion. Urban planning often conflicts with hydrological engineering, straining budgets and limiting green spaces. This review analyzed urban forestry, greenery, and ecohydrological policies in housing and buildings using bibliometric network analysis from Scopus and Web of Science. Key terms such as "urban climate" and "adaptive management" were linked, highlighting challenges in climate change implementation. Vegetation-based rainwater management projects improved resident safety and reduced sewage discharge through soil retention and evapotranspiration. Strategic greenery (green roofs, gardens, parks) enhances water capture and storage. Findings showed that integrating blue-green infrastructure mitigates conflicts between gray infrastructure and hydrological engineering, reducing construction pressures and preserving urban parks. New stormwater management technologies should align with urban ecosystems and housing priorities. Effective ecohydrological policies require careful local planning and appropriate tools to balance sustainability and urban development.
