The concept of 'green infrastructure' has gained significant traction in urban planning as a means to mitigate the adverse effects of climate change. Unlike conventional gray infrastructure, which relies on concrete and steel to manage stormwater, green infrastructure employs natural systems such as permeable pavements, green roofs, and urban forests. These elements not only reduce flooding by absorbing rainwater but also improve air quality, lower urban heat island effects, and enhance biodiversity. However, the implementation of green infrastructure faces challenges, including higher initial costs and the need for specialized maintenance. Despite these barriers, studies suggest that long-term economic and environmental benefits often outweigh upfront investments, making it a viable strategy for sustainable urban development.
