Important Elements And Features Ofneighborhood Landscape For Agingin Place: A Study In Hong Kong, Shu-Lin Shi
Important Elements And Features Ofneighborhood Landscape For Agingin Place: A Study In Hong Kong, Shu-Lin Shi
Faculty of Design & Environment (THEi)
With rapid growth in the aging population around the world, the promotion of aging in place has become more significant in recent years. Many neighborhood landscape elements and features have been revealed by accumulating research findings to be critical to aging in place. However, they are usually studied separately or in small groups. Little has been done to examine the relative importance of these elements and features when brought together, from the older adult’s point of view. In this context, the current study investigated the perceived importance for older adults of 22 selected neighborhood landscape elements and features. A questionnaire …
Tree Density And Diversity In Hong Kong’S Public Housing Estates: Fromprovision 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 and …

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 …

Compact cities and their urban forms have implications on sustainable city development because of high density urban settlement, increased accessibility, and a balanced land use mix. This paper uses quantitative means of understanding urban morphological characteristics with reference to the differing qualities of the urban form (i.e., street patterns, building volumes, land uses and greenery). The results, based on 89 neighborhood communities of Hong Kong, show varying degrees of regional differences in the urban built form supported by numerical statistics and graphical illustrations. This paper offers empirical evidence on some morphological characteristics that can be estimated objectively using modern geospatial …
Occurrence Of Antibiotics And Antibiotic Resistance Genes In Soils Fromwastewater Irrigation Areas In The Pearl River Delta Region, Southernchina, Livia Min Pan, L.M. Chu
Occurrence Of Antibiotics And Antibiotic Resistance Genes In Soils Fromwastewater Irrigation Areas In The Pearl River Delta Region, Southernchina, Livia Min Pan, L.M. Chu
Faculty of Design & Environment (THEi)
The occurrence and distribution of tetracycline (TC) and sulfamethazine (SMZ), and the corresponding antibiotic resistance genes (ARGs) were investigated in six agricultural sites in the Pearl River Delta (PRD) region in southern China. Irrigation water and irrigated soils at two different depths (0-10 and 10-20cm) were analyzed. The total concentrations of TC and SMZ in irrigation water ranged from 69.3 to 234ng/L and from 4.00 to 58.2ng/L, respectively, while the total concentrations of TC and SMZ in irrigated soils ranged from 5.00 to 21.9μg/kg and from 1.30 to 4.20μg/kg, respectively. After long-term irrigation with domestic and fishpond wastewater in the …

Exploring Policy Options To Combat Illegal Micro-Apartments In Hong Kong, Yung Yau, Daniel Chi Wing Ho
Faculty of Design & Environment (THEi)
Illegal building can take multiple forms, including squatter settlements and illegal building extensions. Among the various forms of illegal building, illegal microapartments (IMAs), which take the form of unauthorised subdivided housing units, have recently aroused wide public concern in Hong Kong. On account of their unlawful nature, IMAs pose serious threats to the safety of local communities by undermining structural stability and fire safety in buildings. They may also adversely affect natural lighting and ventilation for building occupants. Fatal fires in buildings with IMAs in recent years have demonstrated the painful consequence of ignoring this issue in the city. Nonetheless, …

Emerging notably in more developed regions, building stock ageing which is characterised by shrinking new completions and falling “mortality” has been posing challenges to various stakeholders in built environment. To find way out of this transition, we need to know how long buildings will last these days and the factors leading to their “mortality”. By using data from 1950s till to date, a comprehensive investigation is conducted to analyse the age composition and life expectancy of public housing stock in Hong Kong. What comes after are survival analysis and empirical analysis of those demolished to identify the key factors leading …

Antibiotics are added to agricultural fields worldwide through wastewater irrigation or manure application, resulting in antibiotic contamination and elevated environmental risks to terrestrial environments and humans. Most studies focused on antibiotic detection in different matrices or were conducted in a hydroponic environment. Little is known about the transfer of antibiotics from antibiotic-contaminated irrigation wastewater and animal manure to agricultural soil and edible crops. In this study, we evaluated the transfer of five different antibiotics (tetracycline, sulfamethazine, norfloxacin, erythromycin, and chloramphenicol) to different crops under two levels of antibiotic-contaminated wastewater irrigation and animal manure fertilization. The final distribution of tetracycline (TC), …
What Is The Impetus To Move? Amenity-Rich Residential Clubs And Retirement Housing Aspirations Of The Soon-To-Be Old, Tris Kee
Faculty of Design & Environment (THEi)
Hong Kong’s population is aging rapidly, yet the city is still struggling to provide an adequate housing supply for its soon-to-be old cohort. By examining the needs and aspirations of the soon-to-be old population through the theoretical frameworks for elderly housing and elderly migration, the relationship between amenity-rich residential clubs and retirement housing aspirations of future retirees become clear. This paper finds that the soon-to-be old cohort is aspired to better medical, leisure, and community facilities in their residential vicinities when considering their retirement living environment, underlining the appeal of amenity-rich residential clubs; however, most of the soon-to-old old cohort …

The maximum vertical uproot resistance (Pmax) of a plant can be used to indicate its stability. Attempts were made to predict the Pmax of a plant empirically from some of its size parameters. In practice, an infinite number of empirical models with different complexities can be formulated. This study presents a Bayesian model class selection method to evaluate the plausibility of each empirical model among a list of model candidates. The models were ranked to identify the most plausible one. A database of vertical uproot resistance of four shrubs and trees native to Hong Kong was first compiled by performing …
