Green Walls Could Cut Street-Canyon Air Pollution
Rows of tall buildings can create a unique urban habitat known as a street canyon. These canyons trap traffic pollutants, limiting their dispersal into the atmospheric boundary layer that extends as high as 2,000 meters above the ground. A new study suggests that vegetation in street canyons may reduce air-pollutant concentrations much more than previously reported and suggests innovative plant...
متن کاملDo green roofs provide habitat for bats in urban areas ?
As the world population continues to increase, with more than 50 percent of people now residing within cities, remaining natural and semi-natural habitats within urban areas play an increasingly important role for people and wildlife (Mortberg and Wallentinus, 2000; Benedict and McMahon, 2002; Jim, 2004; Town and Country Planning Association, 2004; Bierwagen, 2007; Gill et al., 2007; Tratalos e...
متن کاملPerformance evaluation of green roofs in urban runoff reduction
Urbanism directly affects the hydrological cycle. One of the ways to manage runoffs in urban areas that is considered nowadays is green roof creation. Green roof is mainly created in humid and semi-humid areas, and efficiency of green roofs in arid and semi-arid areas has attracted less attention. In the current study, to evaluate the effect of green roof in arid and semi-arid to reduce runoff,...
متن کاملWildflower green roofs for urban landscaping, ecological sustainability and biodiversity
The aim of this trial was to test a wildflower roof in order to show how a country landscape fits in an urban environment. The bio-agronomic performance, the biodiversity dynamics during the two-years experiment, and the pollinating fauna, were analysed. Each plant group was able to efficiently colonize the surface of the roof though in different periods and with various modalities. Thermal ins...
متن کاملHydrologic Restoration in the Urban Environment Using Green Roofs
Loss of natural soil and vegetation within the urban environment can significantly affect the hydrologic cycle by increasing storm water runoff rates and volumes. In order to mitigate these modifications in urban areas engineered systems are developed, such as green roofs, to mimic and replace functions (evapo-transpiration, infiltration, percolation) which have been altered due to the impact o...
