Urban Ecology

Urban ecology is the scientific study of the relationships between living organisms, including humans, and their environment within cities and other urbanized areas. It treats the urban landscape as a complex ecosystem, analyzing the flow of energy, cycling of materials, and the unique patterns of biodiversity that emerge in these human-dominated settings. As a critical applied science informing urban and regional planning, its principles are used to design more sustainable and resilient cities, guiding the development of green infrastructure, managing pollution, and enhancing the well-being of both human and non-human inhabitants.
