Regional ecosystems have been greatly affected by the rapid expansion of urban areas. In order to explore the impact of land use change on net primary productivity (NPP) in rapidly developing cities during the current urbanization process, we quantified land use change in Liaoning province between 2000 and 2010 using net primary productivity as an indicator of ecosystem productivity and health....
Changes in land use disrupt ecosystem patterns and processes and serve as precursors to other biotic and abiotic stressors. Forest ecosystems in the urban core typically differ structurally and functionally from those in rural areas. The overall objective of the study was to determine concentrations of selected air-borne contaminants (N, S, and heavy metals) over space and time and relate these...
Ecological research targeting sustainable urban landscapes needs to include findings and methods from many lines of ecological research, such as the link between biodiversity and ecosystem function, the role of humans in ecosystems, landscape connectivity, and resilience. This paper reviews and highlights the importance of these issues for sustainable use of ecosystem services, which is argued ...
Stormwater management has traditionally focused on the use of conveyances to quickly move stormwater runoff from urban centers into nearby rivers, streams, and lakes. The increased flow caused by impervious surface cover (ISC) leads to runoff rates that are amplified by kinematic processes as they travel through the municipality’s stormwater system. Elevated runoff volumes and rates lead to hig...
The environmental fragility of cities under advanced urbanization has motivated extensive efforts to promote the sustainability of urban ecosystems and physical infrastructures. Less attention has been devoted to neighborhood inequalities and fissures in the civic infrastructure that potentially challenge social sustainability and the capacity of cities to collectively address environmental cha...
A large part (85%) of Brazil’s population lives in urban areas. Roughly half of these dwellers are located in large cities, defined as having 750,000 or more inhabitants. The urbanization trend is due to historical migration movements that occurred mostly before the recent phenomenon of globalization. Nevertheless, the growth of these urban centers is characterized by insufficient public polici...
Urban forest ecosystems are the collections of trees and other woody plants such as bushes shrubs in urban areas, well non-living (sidewalks, buildings, soil) living (people, insects, wildlife) things that interact with them. Most humans throughout world (56%) live ecosystems, so it is important these environments safe, healthy, sustainable. This article will point out forests your life. It als...
