The concept of 'green infrastructure' has gained significant traction in urban planning as a means to address climate change and biodiversity loss. Unlike traditional gray infrastructure, which relies on concrete and steel, green infrastructure integrates natural systems such as parks, green roofs, and permeable pavements into cityscapes. These elements not only manage stormwater and reduce urban heat islands but also provide habitats for wildlife and recreational spaces for residents. However, the implementation of green infrastructure faces challenges, including high upfront costs, maintenance requirements, and the need for interdisciplinary collaboration among ecologists, engineers, and policymakers. Despite these obstacles, studies suggest that long-term economic and environmental benefits, such as reduced energy consumption and improved public health, often outweigh initial investments. Consequently, many cities are adopting adaptive strategies, tailoring green solutions to local climatic and social conditions, rather than applying a one-size-fits-all model.
