“…The novel ecological assemblages of urban environments [47] include native and non-native species in often shifting spatial distributions as the development of the built environment and management of designated greenspaces creates conditions for some plant and fungal species to flourish, and others to become less abundant or locally eradicated. These ecological dynamics are affected by social processes, along with the direct and indirect effects of climate change on species prevalence and abundance [48]. In addition to the conversion of greenspace to hardscape [21,32], remaining greenspaces may be privatised or reconceptualised as spaces for non-consumptive recreation and nature watching, resulting in the closure of de facto commons where foraging previously occurred unhindered [49,50].…”

Abstract:Although hardly noticed or formally recognised, urban foraging by humans probably occurs in all urban settings around the world. We draw from research in India, South Africa, Sweden, and the United States to demonstrate the ubiquity and varied nature of urban foraging in different contexts. Across these different contexts, we distil seven themes that characterise and thereby advance thinking about research and the understanding of urban foraging. We show that it is widespread and occurs across a variety of urban spaces and places. The species used and the local practices vary between contexts, and are in constant flux as urban ecological and social settings change. This requires that urban foragers are knowledgeable about diverse species, harvest locations, and rights of access, and that their practices are adaptable to changing contexts. Despite its ubiquity, most cities have some forms of regulations that prohibit or discourage urban foraging. We highlight a few important exceptions that can provide prototypes and lessons for other cities regarding supportive policy frameworks and initiatives. The formulation of dynamic policy, design, and management strategies in support of urban foraging will benefit from understanding the common characteristics of foraging in cities worldwide, but also will require comprehension of the specific and dynamic contexts in which they would be implemented.

“…The increase of air temperatures in large cities like Manchester will lead to the use of air conditioning systems [15], thus higher electricity demand and higher green house gas emissions. A passive strategy to mitigate heat in cities is to alter the land cover in a way that less solar radiation could be absorbed [16][17][18][19]. Water bodies, high albedo materials, and vegetation can mitigate ambient air temperature to improve energy efficiency and thermal comfort [20][21][22][23].…”

“…The structural attributes of trees are the basis of the multiple ecological services provided by urban forests, such as increasing carbon sinks [63,64], reducing air temperature [28,42,65], and decreasing storm water runoff [66]. In the low RD regions of Harbin, taller and bigger trees were more likely to be associated with lower patch aggregation (IJI) and lower patch areas (TA), as shown by the stepwise regression (Table 4) and RDA ordination results (Figure 8).…”

A better understanding on the associations between road density (RD), urban forest structural-taxonomic attributes, and landscape metrics is vital for forest ecological service evaluations and suitable management in sprawling urban areas with increasing road networks. We chose Harbin, a fast growing provincial capital city in northeast China, as a case study to address this issue. We utilized ArcGIS software (Esri, version 10.0; Redlands, CA, USA) and FRAGSTATS (V4.2.589) to digitize GF-1 images (Gaofen No.1 remote sensing images) to acquire road net characteristic information and landscape metrics of urban forests in Harbin. Together with forest structural-taxonomic attributes from a stratified random sampling survey, statistical methods such as an analysis of variance, a regression analysis, and a redundancy analysis were used to determine the road-dependent differences and to decouple the associations between them. The results indicated that road area percentages, road length/imperious surface area (ISA) ratios, road area/ISA ratios, and road cross-points sharply increased from low to heavy RD areas. This road intensification was strongly associated with increased urban forest area, patch density, and diverse patch shapes; smaller tree sizes, lower tree densities, and diverse tree species compositions were generally observed. Redundancy-based variation partitioning showed that part of the variations in structural-taxonomic attributes of forests could be explained by road intensity characteristics. In low RD (0–1.5 km/km2) regions, the road characteristics significantly affected forest characteristics (Shannon Wiener diversity index, species richness, and evenness index); however, such associations weakened with increasing forest landscape-related associations in medium to heavy RD (1.5–6 km/km2) regions. Our findings highlighted that road development is strongly associated with forest characteristics in Harbin city, and RD-dependent forest landscape regulating management could favor the maximization of forest ecological services that are related to structural and species identities.
