Environmental changes associated with mass urban tourism and nature tourism development in Hong Kong

Hong Kong's tourism is overwhelmingly urban-focused. There is a heavy concentration of tourist and ancillary facilities in a small core urban area. A well-defined tourist business district has evolved with imprints on urban morphology. Hotels and the travel industry have limited direct environmental impacts; recent efforts have reduced energy and water consumption and waste generation. Changing preferences and market diversification call for countryside and resort types of tourism. The mainly young visitors are increasingly interested in the scenic countryside with a well-established country-park system, the tourist potential of which has been neglected. Hitherto rural excursions have been confined to 'honeypots' with little penetration away from main roads. The varied possibilities of nature tourism with ecotourism ingredients can be tapped as an adjunct to the city-based counterpart. New tourist nodes such as scattered resorts and a resort island can bring visitors close to nature. The changing patterns of consumption and the increase in rural visitorship demand measures to forestall environmental degradation.     

Use of environmental teaching kits in Hong Kong

A systematic postal survey of 449 schools in Hong Kong (including kindergartens, primary and secondary schools) was conducted to investigate the use of environmental education teaching kits and to obtain feedback from teachers about the view and comments in using these kits. Results indicated that kindergartens used teaching kits more frequently than secondary and primary schools. Most of the schools found the existing teaching kits helpful. Appropriate content, updated information, attractiveness to students and inclusion of a teachers' guide were considered important criteria in deciding the use of the teaching kits. Good illustrations, quality production and appropriate duration for the class were considered important factors too. The tight teaching schedule was the major hindrance for secondary and primary schools in the use of the environmental teaching kits. However, the main hindrance for using environmental teaching kits in kindergartens was that they did not have sufficient copies. Hong Kong schools would like to see new teaching kits about waste recycling, energy conservation, green behaviour, air pollution, noise pollution, sewage treatment and wildlife endangering, focusing on Hong Kong and China.     

The Value-Action Gap in Waste Recycling: The Case of Undergraduates in Hong Kong

The discrepancy between verbal and actual commitment in waste recycling and environmental behavior is thought to have attenuated the effectiveness of many environmental policy and measures. Studies purport to show the existence of such a value-action gap in environmental issues has been largely based on matching the verbal commitment to environmental value through self-reported environmental behavioral data. Therefore, there is a lack of direct evidence to prove that such a discrepancy exists. This study demonstrates a methodology (contrasting on-site observation with self-reported results) to measure the gap between verbal commitment and actual recycling behavior and provides an explanation on the recycling behavior of students at Hong Kong Baptist University in the hope that the lessons learnt can be generalized to a wider context. Our findings indicate that a gap between verbal recycling commitment and corresponding action does exist in waste recycling on this university campus. By using multiple linear regression analysis, we found that the self-reported recycling behavior of undergraduates cannot be meaningfully explained by most variables previously suggested in the general value-action model.     

An international review of local governance for climate change: implications for Hong Kong

Cities have increasingly become the focal point for climate change initiatives. However, how cities respond to climate change challenges and through what mechanisms have remained largely unexplored. This paper develops a framework for local governance to examine and explain climate change initiatives in cities. Based on the analysis of 20 climate change initiatives in major cities and a detailed case study of Hong Kong, this paper has two main findings. First, local governments at the city level have an important role to play in climate change policies by embracing some key strategies (such as deliberation and partnership) and values (such as equity and legitimacy) of good governance. Second, by comparing and contrasting the experience in other cities, our case study of Hong Kong provides insights about the barriers that may limit a city's ability to adapt to new forms of governance that would enable it to better respond to climate change. The paper concludes by exploring the potential role of local governance as a model to strengthen climate change initiatives at the city level.

Public Discourses of Climate Change in Hong Kong

The changing political environment in Hong Kong is likely to accelerate the transition in environmental policy discourse. Opportunities for critical public involvement are increasing and new environmental discourses are emerging. Yet, previous social surveys did not explore the range of these discourses and few focused on climate change. The paper outlines the public discourses of climate change in Hong Kong. Using Q-methodology, four distinctive discourses were identified, namely Pure Environmentalism, Political Pragmatism, Popular Optimism, and Fair Rationalism. While the first one is climate-centric, the other three are political or social in nature and do not indicate a clear or coherent climate orientation. This suggests that the climate change concern of the Hong Kong public is not tightly embedded into a coherent narrative of social and institutional transformation. Effective climate change governance and policies require strengthening the link between such concern and the public desires for social and institutional transformation. Bringing together the ongoing social movements and environmental campaigns will be instrumental to nurture an active climate citizenry.     

Environmental impacts of iron ore tailings—The case of Tolo Harbour,Hong Kong

Disposal of iron ore tailings along the shore of Tolo Harbour, Hong Kong has altered the adjacent environment. Due to the ever-expanding population, the vast development of various industries, and the lack of sanitary control, the existing pollution problem of Tolo Harbour is serious. The iron ore tailings consist of a moderate amount of various heavy metals, e.g., copper, iron, manganese, lead, zinc, and a lower level of macronutrients. A few living organisms have been found colonizing this manmade habitat. Higher metal contents were also found in the tissue ofPaphia sp. (clam);Scopimera intermedia (crab);Chaetomorpha brychagona (green alga);Enteromorpha crinita (green alga); andNeyraudia reynaudiana (grass). The area can be reclaimed by surface amelioration using inert materials, soils, or organic substrates, and by direct seeding, using nontolerant and tolerant plant materials. Reclamation of the tailings would improve the amenity of the adjacent environment and also mitigate pollution escaping to the sea.     

Comparison of trace metal contents of sediments and mussels collected within and outside Tolo Harbour,Hong Kong

Sediments collected from Tap Mun (within Tolo Harbour) and Yim Tin Tsai (outside Tolo Harbour) were extracted sequentially and the copper, cadmium, and chromium contents were determined. Total contents of copper, cadmium, chromium, and arsenic were also detected by acid digestion. The level of heavy metal extracted was higher in sequential extraction (which extracted all forms of metal ions) than total acid digestion. Among the four heavy metals studied, only copper showed a significantly higher (P<0.001) level in samples collected from Yim Tin Tsai (16.10 mg/kg) than that from Tap Mun (3.19 mg/kg). Such a difference in copper level is mainly attributed to the significantly higher (P<0.05) levels of copper in the organic, carbonate, and sulfide forms, whereas there was no significant difference (P>0.05) in the exchangeable and sorbed forms. Green-lipped mussel (Perna viridis) samples collected from the two sites were dissected into seven parts (gill, byssus, siphon, shell, digestive gland, soft tissue, and adductor muscle) and the concentrations of copper, cadmium, chromium, and arsenic were measured. The highest concentration of copper was obtained in the byssus. A higher concentration of copper was also noted in the mussels collected from Yim Tin Tsai than those collected from Tap Mun. No specific trend was revealed for the other metals tested. Chromium and arsenic concentrations were found to be independent of the body size of the mussels. Copper had a lower concentration in larger mussels and cadmium level was found to decrease with size. In addition, the mussels collected from Tap Mun were much larger than those collected from Yim Tin Tsai.     

The role of perceived effectiveness of policy measures in predicting recycling behaviour in Hong Kong

Hong Kong is a compact and ‘land-hungry’ city where recycling has become an important measure for treating waste and reducing the demand on the limited landfills. The objectives of this paper are to extend the model of recycling attitude and behaviour to explain the relationship between perceived policy effectiveness and recycling behaviour. Previous studies on recycling attitude and behaviour had widely adopted the theory of planned behaviour (TPB) and the norm activation model (NAM), and drawn policy implications from them. Nevertheless, little research has been conducted to investigate the role of perceived effectiveness of policy measures in predicting recycling behaviour. To address this, a model that integrates the TPB and NAM was proposed in this study, and a street survey was conducted to investigate the case. The results illustrate that recycling intention is influenced by subjective norms, perceived behavioural control, moral norms, and awareness of consequences, as well as a newly proposed construct, namely perceived policy effectiveness. The study proved self-reported recycling behaviour (direct behaviour) and support for policy measures (indirect behaviour) are influenced by recycling intention. All in all the Government should provide more recycling bins, guidelines on recycling activities, and should accent what it has been doing to facilitate and encourage recycling.     

Proliferation of nonconforming land uses in agricultural envelope of urban Hong Kong

Until the late 1960s rural Hong Kong had an attractive rustic landscape and a small but active farming population. The recent widespread agricultural decline provided opportunities for urban-oriented activities to invade, mainly as open storage and workshops unsuitable in city areas. Rapid container-port expansion and cross-border China trade generate demands for cheap and accessible land for non-conforming uses (NCU). Rural development control and land-use planning are inherently weak, and formal provision for such uses is lacking. An unfavorable landmark court judgement allows landowners to degrade the countryside. The activities have caused acute environmental problems, telescoped into a small territory, including visual blight, pollution, drainage blockage, loss of wetland habitats, and increased flooding hazard. The distinction between urban and rural has been blurred in the destruction of the valuable countryside heritage. An interim legislative amendment fails to stop unauthorized conversion of farmland. In the long term, an integrated and comprehensive rural planning strategy to conserve inherent elements, as well as accommodating selected urban spillover in properly located and serviced sites, is needed.     

Socio-Ecological Impact and Risk Assessments in the Urban Environment: A Multidisciplinary Concept from Hong Kong

This paper discusses the increasing importance of the environment to social scientists. A multidisciplinary approach is highlighted and it is argued that the social sciences have a more significant role to play in understanding and responding to environmental deterioration than has hitherto been the case. The need for harmonizing multidisciplinarity in appreciating impact assessments is emphasized. A framework for analyzing and containing environmental impacts in Hong Kong is also proposed.     

Trace metal contents of the pacific oyster (Crassostrea gigas) purchased from markets in Hong Kong

Arsenic, cadmium, chromium, and copper concentrations of the Pacific oyster,Crassostrea gigas, purchased from four different markets were determined in this project. In general, gill tissue had the highest proportion of metal contents (34%–67%) when compared with other tissue parts (mantle, viscera, and adductor muscle), except for arsenic, which showed the highest level in adductor muscle (44%). Smaller oysters (longitudinal length of soft body part less than 6 cm) had higher metal levels than larger ones (longitudinal length of soft body part more than 6 cm), except copper. None of the four metals examined showed an obvious seasonal trend, although cadmium levels seemed to be higher in autumn and winter months. Arsenic, cadmium, and copper levels in oysters purchased from different markets and different months obtained in the present study were higher when compared with past reports. Cadmium levels, as high as 10.98 mg/kg (dry weight basis) have been obtained. This approaches the safety limit that may be hazardous to human health. Continual monitoring of cadmium and other trace metals of toxicological significance to man in Hong Kong seafood is recommended.     

Improving visitor management approaches for the changing preferences and behaviours of country park visitors in Hong Kong

This study identified the changing preferences of country park visitors in Hong Kong and the potential for such changes to have further negative impacts on the ecologically sensitive areas of country parks. A questionnaire was used to collect feedback from 644 country park visitors to understand their preferences and visitation patterns. To investigate visitors’ preferences and behaviours and to develop better visitor management strategies, the survey data were compared with studies conducted 20 years ago. The results showed that the most popular nature‐based activities of 20 years ago, namely, picnicking and barbecuing, have significantly declined in popularity, while other activities, namely, nature studies and nature photography, have surged in popularity in recent years. These changes in visitor preferences have directly increased the negative impacts of visitors on country parks as they dispersed away from the high intensity recreation zones to the ecological sensitive areas. This emerging group of country park visitors has not been fully considered in the existing approach to visitor management and may irreversibly impact the ecological value of country parks. In this study, visitor management in Hong Kong's country parks was reviewed based on these research findings, and potential improvements were suggested.     

The conservation benefits of cost-effective land acquisition: A case study in Maryland

Economic theory asserts that to achieve maximum conservation benefits land acquisition needs to be cost effective. Yet the most common planning technique used by land conservation organizations is ‘benefit-targeting’ that focuses only on acquiring parcels with the highest benefits and ignores costs. Unlike most of the literature which focuses on covering problems, this research applies optimization techniques to achieve maximum aggregate conservation benefits for an ongoing land acquisition effort in the Catoctin Mountain Region in central Maryland. For this case study, optimization yields additional conservation benefits worth an estimated $3.1–$3.9 million or achieves the same level of conservation benefits but at a cost savings ranging from $0.9 to $3.5 million, depending on the initial budget size. Finally, the highest efficiencies are achieved in low budget scenarios, like those most prevalent in conservation efforts.     

China's small coal mine policy in the 2000s: A case study of trusteeship and consolidation

China has been trying to improve the safety and environmental performances of small coal mines (SCMs) in 2000s through measures of trusteeship and consolidation. The question whether such policy and practice can sustain small scale mining is interesting academically and important practically for China and the world. This paper finds that the Chinese SCM policy has been switched from encouragement to restriction for legal SCMs and from privatization to nationalization in some provinces in the past 10 years. Legal SCMs face pressure to be expanded continuously and to be absorbed or consolidated by large coal mines, which often are state owned. Unexpectedly, financial resources may not be a big constraint nowadays due to availability of private equity investment resources. The paper argues that both the trusteeship and consolidation approaches may only be able to sustain SCMs in the short run. A more sustainable measure is to establish a stable, transparent and inclusive legal and fiscal framework. This paper concludes that those trusteeship approaches may be applicable to restructuring small scale mines in other countries; however, the consolidation practice in China's is unique and thus may not be applicable to others.     

Evolution of the landscape as a response of a demographic change. A case study in the Duero riverside,Spain

The Arribes del Duero area, in western Spain, at the border with Portugal, is suffering a drastic change in the landscape, as a response of the diminution of population. Traditional tasks related to agriculture have been abandoned, and heavy sheep farming on the area is provoking the impoverishment of soils. The effect derived from these actions is the disintegration of the terraces, which are one of the major attractions for tourists visiting the region. We propose that incentives for local people could help to develop those traditional labours to recover the landscape, together with the promotion of immigration of families with school-age children, could bring back the economy to the area.     

Economic analysis of reform policies for small coal mines in China

Over the last three decades, China’s coal industry has achieved dramatic increases in coal production, both in absolute terms and relative to the world as a whole. This achievement is due largely to its coal policies. Yet facing increasing pressures of environmental sustainability and market transition, the Chinese government was forced to make deep reforms and adjustments to regulate the coal industry effectively. This paper presents an historical overview of China’s coal economic policies, paying particular attention to the current reform policy of closing mines and restricting the yield for the small coal mines (SCMs) in the context of economic theories and methods. We argue that the SCM closure policy would not likely be efficiently enforced if a feasible market mechanism were not built up. The failure of closure policy is due largely to problems of property rights, coal pricing, ownership, and objectives.     

Farmers' involvement in landscape activities: an analysis of the relationship between farm location, farm characteristics and landscape changes in two study areas in Jutland, Denmark

Farmers are important agents in rural landscape management as they modify landscape elements to suit their needs. The purpose of this study is to investigate if patterns of landscape activities undertaken by farmers are related to certain farm characteristics and if landscape activities vary from one location to another. With this purpose, we investigated the differences between the level of farmers' involvement in landscape activities in two study areas in central Jutland, Denmark. Particular attention was given to the analysis of the type and extent of landscape activities and their relationship with farm characteristics. In both study areas, landscape activities leading to a more extensive type of land use predominate. However, a multivariate analysis implemented on the set of landscape activity data reveals significant differences between the two study areas. Hedgerow planting and removal is more common in S?nder Omme, while pond digging and cultivation of permanent grass lands are characteristic activities in Gadbjerg-Givskud. Moreover, the proportion of farmers involved and the area affected by different landscape activities is larger in S?nder Omme than in Gadbjerg-Givskud. The farms of the two areas are different in terms of production type, size and socio-economic characteristics. These characteristics represent significant relationships with landscape activities. However, they are not sufficient to explain the differences between landscape activities undertaken in the two areas. The differences are caused by unique cultural and biophysical environment, which influence and modify the relationship between farm characteristics and landscape activities in a distinct manner for each study area.     

SMEs and voluntary environmental initiatives: a study of stakeholders' perspectives in Hong Kong

The environmental performance of Hong Kong's businesses is currently perceived as rather poor. Small and medium-sized enterprises (SMEs) in particular are mostly unaware of the environmental impact of their business. Government and professional bodies have recently started to develop various initiatives to improve the SME sector's awareness of environmental and social issues, and external factors such as supply chain requirements, consumer preferences and energy prices are also exerting a growing influence. Based on extensive interviews with representatives of seven key stakeholder groups, this paper explores the effectiveness of such drivers to engage SMEs with environmental change and corporate social responsibility (CSR). It finds that most existing efforts, such as environmental support programmes and award schemes, do not have a great impact on the environmental and social performance of Hong Kong's SMEs.
