Rupasinghe Green infrastructures such as living walls are technological solutions to replace the declined greenery at urbanized environment and also reliable applications for thermal regulation in buildings through insulation effect and escalates the energy use efficiency. Thermal comfort and local climate are spatiotemporally variable. The existing research gap should be addressed by evaluating the performance of vertical green...
Assessing regulating ecosystem services provided by the Ege University Rectorship Garden
01. August 2018
Publication date: August 2018 Source:Urban Forestry & Urban Greening, Volume 34 Author(s): Cigdem Coskun Hepcan, Serif Hepcan Urban ecosystem services are generated in a diverse set of natural and managed urban green areas, including parks, urban forests, cemeteries, vegetated corridors, vacant lots, gardens, yards, and campus areas. Private gardens are generally undervalued for the ecosystem services they provide along with the other urban green areas. This paper aims to calculate three regulating ecosystem services; runoff retention, carbon storage and sequestration...

01. August 2018
Publication date: August 2018 Source:Urban Forestry & Urban Greening, Volume 34 Author(s): Shaowei Lu, Xinbing Yang, Shaoning Li, Bo Chen, Yan Jiang, Di Wang, Lan Xu We selected 6 species of landscape plants growing under different pollution levels and performed quantitative determination of PM2.5 adsorption. We compared the measured adsorption to the leaf morphology and the water-soluble ion content. The results indicated that the pollution level and plant leaf surface PM2.5 adsorption capacity were positively correlated. There was variation in the leaf area...
Assessing the impact of street lighting on Platanus x acerifolia phenology
01. August 2018
Publication date: August 2018 Source:Urban Forestry & Urban Greening, Volume 34 Author(s): Luciano Massetti Autumn phenology is an important part of the tree growing season that is still poorly understood. In addition to the environmental factors that might affect its timing, there are artificial effects introduced by modern society that could interfere with it, such as the increasing use of artificial light to illuminate urban nights. This study investigates the relationship between outdoor public lighting and leaf senescence of Platanus x acerifolia that constitutes with...
Loading experienced by a tie-in point during ascents
01. August 2018
Publication date: August 2018 Source:Urban Forestry & Urban Greening, Volume 34 Author(s): Brian Kane Working in trees is an inherently dangerous profession, with a higher than average fatality rate. Climbers secure themselves with a rope and harness to a tie-in point to ascend into and work in a tree, but it can be difficult—if not impossible—to assess the safety of a tie-in point from the ground. Very little experimental work has described the loads associated with ascending into and working in trees, but it is critical to understand them to assess safety. We measured...
The influence of spatial configuration of green areas on microclimate and thermal comfort
01. August 2018
Publication date: August 2018 Source:Urban Forestry & Urban Greening, Volume 34 Author(s): Sahar Sodoudi, Huiwen Zhang, Xiaoli Chi, Felix Müller, Huidong Li It has been shown that the spatial configuration of a green area can strongly influence its cooling effect. However, the specific correlation has not been sufficiently studied. To systematically clarify the correlation between the spatial configuration and the cooling effect of green areas, 25 idealized scenarios are designed and simulated using the microclimate model ENVI-met. These 25 scenarios represent green...

01. August 2018
Publication date: August 2018 Source:Urban Forestry & Urban Greening, Volume 34 Author(s): Emmanuel Mwakiwa, Tendai Maparara, Simbarashe Tatsvarei, Nolyn Muzamhindo The poor economic situation in Zimbabwe has forced many households to engage in urban agriculture. With the increasing number of households engaging in the practice, a local NGO in 2009 introduced community gardens in the city of Gweru to vulnerable households as a new development initiative. We examine the feasibility of community resource management in these gardens using a blend of econometrics and...
Digging for the roots of urban gardening behaviours
01. August 2018
Publication date: August 2018 Source:Urban Forestry & Urban Greening, Volume 34 Author(s): Olivia Lewis, Robert Home, Thanasis Kizos Urban green spaces make a significant contribution to the social and ecological environment in cities, and the decisions of green space managers have direct impacts at both local and city scales. However most studies have focussed on public green spaces, despite privately managed gardens collectively forming a large proportion of urban green. The aim of this qualitative paper is to understand why people become involved in gardening and why...

Publication date: August 2018 Source:Urban Forestry & Urban Greening, Volume 34 Author(s): L. Bortolini, G. Zanin Since spring 2011 the roof of a building on the Agripolis Campus of the University of Padova (Italy) has been used as a drainage area for two rain gardens with a circular area of about 10% and 20% of the drainage area respectively. To improve soil infiltration, the topsoil was removed up to the depth of 1 m and filled with a mix of 50% sand, 25% compost and 25% of the existing topsoil. Herbaceous perennials were selected and planted to test their adaptability...
Impervious surface thresholds for urban tree site selection
01. August 2018
Publication date: August 2018 Source:Urban Forestry & Urban Greening, Volume 34 Author(s): Michael G. Just, Steven D. Frank, Adam G. Dale Impervious surfaces are a ubiquitous urban feature that increase temperature and tree drought stress and are a demonstrated indicator of Acer rubrum L. tree condition and insect pest abundance. We examined the relationship between A. rubrum condition, impervious surface cover, and Melanaspis tenebricosa (Comstock) abundance, a primary herbivore of urban A. rubrum, in eight cities across the southern distribution of A. rubrum. We...

01. August 2018
Publication date: Available online 20 June 2018 Source:Urban Forestry & Urban Greening Author(s): Baojie He, Jin Zhu Community gardens are very popular in developed countries, providing multiple benefits to inhabitants. In developing China, residents in many emerging urban communities of China have been appropriating and reclaiming public open spaces intentionally as a leisure opportunity and transforming their entertainment functions into vegetable plots, which has caused a series of conflicts and disputes. However, this issue of informal community gardening has rarely...
Index for evaluation of public parks and gardens proximity based on the mobility network: A case study of Braga, Braganza and Viana do Castelo (Portugal) and Lugo and Pontevedra (Spain)
01. August 2018
Publication date: Available online 19 June 2018 Source:Urban Forestry & Urban Greening Author(s): Bruno MARTINS, António NAZARÉ PEREIRA Urban green space (UGS) indices are increasingly used and are mentioned by many authors. However, while indices relating to the amount of green space are widespread, other important information about UGSs (including proximity) is somehow disregarded. This is noticeable in the Iberian Peninsula, for which studies relating to proximity of public parks and gardens (PG) are not easily found. The aim of this study is to quantify proximity as a...

The Impact of Ancient Tree Form on Modern Landscape Preferences
01. August 2018
Publication date: Available online 18 June 2018 Source:Urban Forestry & Urban Greening Author(s): Joseph B. Townsend, Susan Barton Empirical studies of the relationship between aspects of the landscape and human emotions have been fruitful over the last few decades. In fact, we are awash in data that describes a correlation between natural landscapes and positive human feelings. While this plethora of data has been useful to various disciplines, it has not lead to an explanatory theory as to why and how the landscape should have this affect This paper proposes that the...
