Co-Designing Mobile Collection Points With Older Persons To Promote Green Attitudes And Practices In Hong Kong, Alex Pui-Yuk King Jan 2019

Co-Designing Mobile Collection Points With Older Persons To Promote Green Attitudes And Practices In Hong Kong, Alex Pui-Yuk King

Technological and Higher Education Institute of Hong Kong (THEi) Staff Publications

Hong Kong has actively promoted various recycling campaigns over the last decade, but much improvement is still needed, as only a small portion of the region’s waste is collected for recycling in towns. By exploring the latent needs and concerns of the public through involving older people and recyclers, the recycling process can be streamlined and made more effective. This paper reports on a participative workshop in which older people, representatives of local recyclers and designers discussed future directions for the design of mobile collection points. This process was facilitated by quick models and developed through an iterative process ...


Tree Density And Diversity In Hong Kong’S Public Housing Estates: From Provision Injustice To Socio-Ecological Inclusiveness., Louis Shing Him Lee, C.Y. Jim, Allen Hao Zhang Jan 2019

Tree Density And Diversity In Hong Kong’S Public Housing Estates: From Provision Injustice To Socio-Ecological Inclusiveness., Louis Shing Him Lee, C.Y. Jim, Allen Hao Zhang

Socio-economically underprivileged urban communities might suffer from restricted access to urban forests. Environmental injustice research on urban greenery in Asian cities is lacking. Public housing estates in Hong Kong, accommodating low-income households and over half of the 7.45 million population, were investigated for injustice in tree provision. Two clustering schemes used socio-economic and ecological characteristics to classify 93 estates. Factor analysis of 14 socio-economic variables identified four factors related to deprivation, namely ageing population, overcrowding, working poor with high academic qualifications, and marginalised language minorities. Principal component analysis of six ecological indices returned two components related to tree density ...

Tree Distribution, Morphology And Modelled Air Pollution In Urban Parks, Yang Xing, Peter Brimblecombe, Sifeng Wang, Allen Hao Zhang

Trees offer a range of ecosystem services and remain important in providing human benefits. However, emerging literature questions the long-accepted view of trees being able to improve air quality in urban parks. The aerodynamic effect of trees was identified as a major reason for the change of pollutant distribution in near-road parks, where trees can act as porous barriers and cause localised concentration increase. Although not yet fully developed, planting strategies aiming to mitigate the negative effect of vegetation on air quality should be encouraged in future park design. In this study, we explored the effect of tree planting design ...


Species Diversity And Spatial Pattern Of Old And Precious Trees In Macau, Allen Hao Zhang, Po Ying Lai, Chi Yung Jim Jan 2019

Species Diversity And Spatial Pattern Of Old And Precious Trees In Macau, Allen Hao Zhang, Po Ying Lai, Chi Yung Jim

Technological and Higher Education Institute of Hong Kong (THEi) Staff Publications

The world's fast pace of urbanization has exerted profound pressure on urban trees. With over 400 years of urban history, Macau has developed an exceptionally high population density and ultra-compact mode, yet it permits survival of interesting and diverse heritage trees. These outstanding living remnants connote special values in history, ecology and botany. In conjunction with commemorative importance, they have been designated as Old and Precious Trees (OPT). This study evaluated the OPT with reference to: (a) species diversity and evenness; (b) spatial distribution; (c) tree dimensions, age and health; and (d) spatial differentiation of tree attributes by four ...

Spatial Differentiation Of Heritage Trees In The Rapidly-Urbanizing City Of Shenzhen, China, Po Ying Lai, Cy Jim, Guang Da Tang, Wen Jun Hong, Hao Zhang Jan 2019

Spatial Differentiation Of Heritage Trees In The Rapidly-Urbanizing City Of Shenzhen, China, Po Ying Lai, Cy Jim, Guang Da Tang, Wen Jun Hong, Hao Zhang

In China, heritage trees are actively surveyed and reported. Over 300 relevant published articles were reviewed to assess the contents, trends and geographical distributions of the investigations. The majority of the heritage trees studies in China were found in the eastern provinces and published within 2010–2014. Most studies reported surveys on all old trees. For studies focused on single species, Ginkgo (Ginkgo biloba) and Chinese Yew (Taxus chinensis) was most frequently reported. Unlike the champion tree registry in the US and other countries, the tree registry in China emphasized more on the tree age than the size. We then ...
