Urban Ecosystem Ecology (original) (raw)

Humans significantly affect their ecosystem. Nowhere is this more evident than in our towns and cities around the world. We have options when it comes to the sustainability of our cities. We have to pay attention to meeting the needs of today without compromising the needs of the future. However, to truly understand those options, we need to have the best knowledge available so that we can make the best decisions possible. It has everything to do with the stewardship of our natural resources, while at the same time using those resources to meet the needs of today’s urban population. This volume deals with the impacts of urbanization on the environment— soils, air, and water quality, the animals and humans who live there—and offers some solutions to contemporary problems. Its coverage exemplifies the wide range of specialties in the agronomic sciences and shows how scientists define ecosystem functions and solve problems. To read this book will give instruction in how agronomy, an ar...

Urban Ecological Systems: Linking Terrestrial Ecological, Physical, and Socioeconomic Components of Metropolitan Areas

Annual Review of Ecology and Systematics, 2001

▪ Ecological studies of terrestrial urban systems have been approached along several kinds of contrasts: ecology in as opposed to ecology of cities; biogeochemical compared to organismal perspectives, land use planning versus biological, and disciplinary versus interdisciplinary. In order to point out how urban ecological studies are poised for significant integration, we review key aspects of these disparate literatures. We emphasize an open definition of urban systems that accounts for the exchanges of material and influence between cities and surrounding landscapes. Research on ecology in urban systems highlights the nature of the physical environment, including urban climate, hydrology, and soils. Biotic research has studied flora, fauna, and vegetation, including trophic effects of wildlife and pets. Unexpected interactions among soil chemistry, leaf litter quality, and exotic invertebrates exemplify the novel kinds of interactions that can occur in urban systems. Vegetation ...

Stewardship of the Biosphere in the Urban Era Coordinating Lead Authors

We are entering a new urban era in which the ecology of the planet as a whole is increasingly influenced by human activities (Ellis 2011; Steffen et al. 2011a, b; Folke et al. 2011). Cities have become a central nexus of the relationship between people and nature, both as crucial centres of demand of ecosystem services, and as sources of environmental impacts. Approximately 60 % of the urban land present in 2030 is forecast to be built in the period 2000–2030 (Chap. 21). Urbanization therefore presents challenges but also opportunities. In the next two to three decades, we have unprecedented chances to vastly improve global sustainability through designing systems for increased resource efficiency, as well as through exploring how cities can be responsible stewards of biodiversity and ecosystem services, both within and beyond city boundaries.
