Abstract

The rate of urbanization has been increasing and making megacities more socio-ecological complicated with the environmental resilience as the indicators of human well-being being more pressured. Historical forms of city planning frequently focus on grey infrastructure and lead to the division of the ecosystem, bad air quality, and increased exposure to the effects of climate change. This study reinvents the urban ecology with a proposal of the overall implementation of the green infrastructure into the spatial, functional, and cultural tissue of megacity design. Incorporating urban planning, ecological, and environmental engineering interdisciplinary insights, the paper approaches the question of how green infrastructure, including parks, green roofs, permeable surfaces, urban forests, and reclusive waterways may be used both as ecological networks and as resources by local communities. The study is conducted through spatial analysis, case studies of global megacities and predictive modeling to determine the ability of such interventions to enhance biodiversity, counteract urban heat islands, strengthen community stormwater management practices, and social cohesion. The results show that how green systems designed with strategy can play a protective role as ecological corridors across several levels of the urban setting in transregional cities can enable species migration, and serve human recreation and wellbeing at the same time. In addition, the report highlights the importance of governance design that combines stakeholder local input, resilient policy system, and intersectoral partnerships to provide an equitable access and sustainability. This contribution to the discussion of regenerative urbanism brings out the green infrastructure as an element of designing cities not as an additional feature of speeding upbuilding the urban rather than its add-on feature. The given framework provides practical recommendations on how the ecological functionality can be imbibed into the blueprint of future megacities so that fast-paced urbanization can coincide with the requirements of planetary health. Finally, the study promotes such a paradigm shift as the one from the ecologically disruptive cities to the living regenerative ones in balance with their natural surroundings.
