Restorative Urbanism and the Social Dynamics of Biophilic Design in Aging Urban Centers

As global urbanization reaches unprecedented density in 2026, the structural disconnect between residents and natural systems has created "socially sterile" environments. Biophilic Urbanism—the integration of intentional natural systems into the built fabric—offers a framework for social restoration. This paper investigates the impact of "Living Infrastructure" and "Pocket Forests" on the social cohesion and mobility of elderly residents in high-density metropolitan zones. Through a multi-site ethnographic study and spatial mapping across four distinct climates, we analyze how nature-integrated design facilitates intergenerational interaction and reduces social isolation. Our findings indicate that biophilic "Green Plazas" increase the duration of outdoor social activities by 35% among residents over the age of 65. The study concludes that biophilic design is a vital tool for urban resilience, transforming passive transit zones into active, socially restorative communal spaces.
