“…Similar results were obtained for organic matter (Figure 8), phosphorus, and coliforms, with concentrations for GRs that were significantly higher than the control cases' concentrations (Table 3). These are similar to results presented in previous studies, indicating GRs as a source of organic matter [7,46], phosphorus [22,24,25,47,48], pathogens [48], and total dissolved solids [1,30], as well as the pH neutralization effect from GRs [1,22,25,26,31,[49][50][51][52]. GRs had significantly higher concentrations for total Kjeldahl nitrogen (TKN), nitrates, and nitrites than the control cases, confirming the findings of Aitkenhead-Peterson et al [46], Greogoire and Clausen [53], Moran et al [54], and Whittinghill et al [55].…”

Green roofs (GRs) are a feasible solution for mitigating increased runoff volumes in urban areas. Though many studies have focused their analysis on the quantity and quality of GR runoff, with respect to the relevance of specific site conditions in GR performance, the information gathered for the tropical Andes is not sufficient. This study assessed the hydrological performance and runoff water quality of 12 green roof modular systems located at the Universidad de los Andes campus (Bogotá, Colombia). Based on 223 rainfall events spanning a 3-year period, average rainfall retention was 85% (coefficient of variation = 29%). t-tests, the Welch Test, multiple linear regressions, and correlation analysis were performed in order to assess the potential effect of air temperature, substrate type, vegetation cover, relative humidity, antecedent dry weather period (ADWP), rainfall duration, and rainfall maximum intensity. In some cases, GR design variables (i.e., substrate type and vegetation cover) were found to be significant for describing rainfall retention efficiencies and, depending on the GR type, some hydrological variables were also correlated with rainfall retention. Rainfall and GR runoff from 12 rainfall events were also monitored for total Kjeldahl nitrogen (TKN), nitrates, nitrites, ammonia, total phosphorus (TP), phosphates, pH, total dissolved solids (TDS), total suspended solids (TSS), color, turbidity, biological oxygen demand (BOD), chemical oxygen demand (COD), total coliforms, metals (i.e., zinc, copper, nickel, lead, selenium, aluminum, barium, boron, calcium, strontium, iron, lithium, magnesium, manganese, potassium, sodium), and polyaromatic hydrocarbons (PAHs). The results obtained confirmed that GR systems have the ability to neutralize pH, but are a source of the rest of the aforementioned parameters, excluding PAHs (with concentrations below detection limits), ammonia, TSS, selenium and lithium, where differences with control cases (rainfall and plastic panel runoff) were not statistically significant. Substrate type, event size, and rainfall regime are relevant variables for explaining runoff water quality.

“…Moreover, diverse urban greening models need to be considered. For example, green roofs has been approved a valuable tool to conciliate the greening of cites with ecological conservation and environmental quality improvements (Farrell et al, 2012;Chen, 2013;Madre et al, 2013), yet this type of urban greening is seldom utilized in the study area. Some remnant natural plant, such as stonewall trees, also need to be protected for enriching urban biodiversity (Jim, 2013).…”

a b s t r a c tUrban forest construction is believed as an effective method to preserve urban biodiversity and restore urban green ecosystem. However, in some fast-urbanizing towns, the most urban flora in the built-up area was almost totally manmade, where is new expanded areas mainly transformed from cultivated lands. How such urban flora contribute to local and regional diversity is seldom quantitatively tested. In this study, we conducted a comprehensive investigation of man-made urban flora in 15 fast-urbanizing towns in Shandong Peninsular, China, to explore the effect of urban greening on the local and regional plant diversity. The results that showed huge investment to urban greening contribute to high urban green coverage but do not foster high plant diversity. Exotic species has lower overall dissimilarity between town pairs than native in either cultivated or wild flora. Urban greening does not result in high proportion of exotic species, however, either wild flora or cultivated flora show homogenizing tendency due to the expansion of exotic species. Nevertheless, the main driving forces are different: the wild flora are homogenized by diminished species richness difference while the cultivated flora due to the decreased species replacement. We therefore suggest biodiversity conservation should be more considered and strengthened in further urban greening. Our study could also provide useful reference data in biotic homogenization research in China.

“…In the Austrian capital Vienna, financial support is granted per m 2 of green roof (Brudermann & Sangkakool, 2017). Chen (2013) reviewed city policies in several Asian and American cities, and found policies and by-laws favoring green roofing in Singapore, Japan, Hong Kong, USA and Canada. Those countries are making a strong initiative to install green roofs during construction of new buildings, and are retrofitting old ones so green roofs can be added in the near future (Vijayaraghavan, 2016).…”
