A glimpse on the history of green urbanism of the U.S. as found in Karlenzig's, et al. ‘How Green is Your City’ book (2007, 06–07). The concept had a gradual start in the late 1800s, when some large cities of the United States (U.S.) started using advanced drinking water, sewage and sanitary systems.
In urban green spaces, trees filter out man-made pollutants. Air quality data collected on cities with and without urban green space has shown that areas with an abundance of trees have considerably less air pollutants, i.e. O 3, PM 10, NO 2, SO 2, and CO. [42]
Community Greens, sometimes referred to as backyard commons, urban commons, or pocket neighborhoods, are shared open green spaces on the inside of city blocks, created either when residents merge backyard space or reclaim underutilized urban land such as vacant lots and alleyways. These shared spaces are communally used and managed only by the ...
The term white paper originated with the British government, with the Churchill White Paper of 1922 being an early example. [4] In the British government, a white paper is usually the less extensive version of the so-called blue book, both terms being derived from the colour of the document's cover.
Environmental gentrification is commonly understood as the process in which urban green space improvements lead to the displacement of lower-income communities, although the exact definition remains a topic of debate. [10] Green gentrification is closely related to urban planning and climate mitigation efforts.
In urban planning and design, blue space (or blue infrastructure) comprises areas dominated by surface waterbodies or watercourses. In conjunction with greenspace (parks, gardens, etc. specifically: urban open space), it may help in reducing the risks of heat-related illness from high urban temperatures (urban heat island). [1]
They are an important component of urban green infrastructure systems. Urban forests use appropriate tree and vegetation species, instead of noxious and invasive kinds, which reduce the need of maintenance and irrigation. [53] In addition, native species also provide aesthetic value while reducing cost.
Urban Forestry and Urban Greening is a peer-reviewed scientific journal published by Urban & Fischer, an imprint of Elsevier. The editor-in-chief is Wendy Chen. [ 1 ] Coverage includes research regarding urban and peri-urban forests and other nearby vegetation.
