The concept of 'green infrastructure' has gained 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 utilizes natural processes such as soil absorption and plant transpiration. Parks, green roofs, and permeable pavements are prime examples. Research indicates that these systems not only reduce flood risks but also improve air quality and urban biodiversity. However, their effectiveness depends on careful design and maintenance, as poorly implemented projects can lead to soil compaction or waterlogging. Critics argue that green infrastructure alone cannot replace traditional drainage systems in extreme weather events, suggesting a hybrid approach is more resilient. Proponents counter that the co-benefits, including mental health improvements and energy savings, justify broader adoption, even if initial costs are higher than anticipated.
