Tourism stakeholders’ perceptions of national park management in Norway   总被引:1,自引:0,他引:1  
Local tourism firms represent an important stakeholder interest in national parks. The present study examines these stakeholders’ perceptions of management processes and their assessments of the resulting management plans and operations. This research is based on qualitative interviews with representatives of tourism businesses in two different national park settings in Norway – Rondane National Park and Jotunheimen National Park. The findings illustrate that despite their general support for the national park status, the local tourism stakeholders interviewed had experienced only minor involvement in the management planning process, and had had very little influence in the final management decisions. They believed that opportunities for business operations were lacking due to excessive management restrictions, and that managers lacked competence with regard to business management and tourism development issues. In addition, they thought that management authorities should more explicitly include sustainable tourism development in their visions and goals. Based on the findings, it is assumed that there is potential for local tourism operators to take greater responsibility in planning processes and management operations. It is concluded that measures should be taken to foster durable social links and trustworthy planning partnerships between responsible managers and local tourism stakeholders in the two national parks.  相似文献

Abstract

National parks in Canada operate under the dual mandate of conservation and visitor use, which involves balancing ecological integrity and nature-based tourism activities. Climate-induced environmental change may increase the existing tension between conservation and visitor use as major tourism resources located in protected areas (PAs) are projected to undergo large-scale changes. This study draws upon the behavioural approach, scenario planning, and landscape visualizations to examine the relationship between climate change impacts, visitor perceptions, and visitor experience management at the Athabasca Glacier in Jasper National Park, Canada. Four tourism development scenarios defined by two management drivers (ecological integrity and visitor demand) with corresponding storylines and visualizations were developed for 2050. The visualized scenarios were presented to visitors (n?=?304) in a survey to understand potential implications on visitor satisfaction. The results suggest that park managers need to find a balance between ecological integrity and visitor use in a way that ensures commercialized tourism development is limited, educational material is prioritized, and ecological integrity is maintained. While understanding the behaviour of future tourists is complex, it is a critical component of climate change adaptation planning and decision-making processes that needs to be prioritized by policymakers and PAs managers.  相似文献

Ecotourism has become the focal point of a wide range of private and public sector development initiatives in the countries of the Western Indian Ocean. The 2008 “Regional Strategic Action Plan for Coastal Ecotourism Development in the South Western Indian Ocean” aimed at both a strategic assessment of current achievements and the development of recommendations for policy action. Drawing on the research data initially gathered for this report, the article demonstrates the importance of fostering criteria for ensuring medium and long-term economic viability in the assessment of sustainable ecotourism development performance, both at micro- and macro-economic levels. The arguments are presented in the form of eight lessons learnt, and the article approaches the question of economic viability at the different levels of enterprises, projects and products, and in terms of public policy and planning.  相似文献

Abstract

Protected areas (PAs) worldwide are facing increasing visitation and complexity. Mounting pressures from the private sector are intensifying the risks associated with overtourism. The increasing strategic importance of PAs for the communities and regions in which they are situated requires improved management effectiveness; yet, recent studies indicate significant and growing systemic risk. Worldview analysis can be a valuable tool for building consciousness and informing the evolution of PA planning and management. Directed content analysis was used to examine two Visitor Use Plans developed for the Coyhaique National Reserve, located in the iconic Patagonia cultural area of southern Chile. The plans were developed using distinct planning frameworks, with different underlying assumptions. Research questions focused on how modernist, postmodernist and integral worldviews were expressed within the two plans. Worldviews were explored in both manifest and latent manners, considering plan text, models and overall context revealing patterns and links between the plans and planning frameworks that guided their development. Rich context and a thorough discussion of methods assists with the incorporation of worldview evaluation within PA management theory, informing the continuing development of knowledge and capacities that can better prepare PAs for future challenges.  相似文献

Predicting future events, trends and issues that may affect the tourism industry is not an exact science. Already the 21st century has seen a number of significant, radical and unexpected events, including September 11, SARS and, more recently, the worldwide economic downturn and natural disasters, such as earthquakes and cyclonic activity. Within this increasingly volatile global landscape, more than ever there is a need for the tourism industry to embrace a disciplined, structured and continuous approach to identifying and monitoring future trends and issues to inform policymaking and strategic planning. Yet in Australia it has been claimed that a preoccupation with marketing and short-term tactical planning, at the expense of long-term, strategic thinking, has led to limited planning perspectives for tourism. To explore these claims, this paper reports on a content analysis of 28 Australian national-level tourism strategic planning documents across a 10-year period (2000–2009 inclusive).  相似文献

This study tests the model of the relationship between corporate entrepreneurship and strategic management, developed for the manufacturing industry by Barringer and Bluedorn (1999 Barringer, B. R. and Bluedorn, A. C. 1999. The relationship between corporate entrepreneurship and strategic management. Strategic Management Journal, 20: 421444. [Crossref], [Web of Science ®] [Google Scholar]), in the hospitality industry. The findings show some similar and different results from the research of Barringer and Bluedorn (1999 Barringer, B. R. and Bluedorn, A. C. 1999. The relationship between corporate entrepreneurship and strategic management. Strategic Management Journal, 20: 421444. [Crossref], [Web of Science ®] [Google Scholar]). Like manufacturing companies, hospitality companies perceive that corporate entrepreneurship is influenced by four strategic planning practices: environmental scanning intensity, planning flexibility, planning horizon, and locus of planning. Hospitality companies, however, consider that financial controls, not strategic controls, positively influence corporate entrepreneurship intensity. These findings have practical applications for hospitality corporations that are attempting to become more entrepreneurial, and will also help researchers to better understand the relationship of corporate entrepreneurship and strategic planning.  相似文献

Are European national risk prevention regulations reflecting different cultural attitudes towards risk? This article replies positively to this question by elaborating the results of an investigation led between 2004 and 2008 by the Joint Research Centre of the European Commission. The investigation focused on the European national implementations of Article 12 of Directive Seveso II on Dangerous Substances (96/82/EC) and aimed at providing an overview of different methodological approaches to the matter of land use planning in areas subject to the risk of major accidents. Five countries were selected for in‐depth analysis and comparison. This article focuses on one aspect of their different approaches to land use planning in at‐risk areas that was not considered by the European investigation: the influence of national cultural backgrounds on the implementation of Article 12 within the respective national legislations and practices. To explain whether different cultural orientations may have affected them, the article refers to one cultural index in particular, namely the uncertainty‐avoidance index (UAI) proposed by the Dutch sociologist Geert Hofstede. This index provides a key of reading of the different methodological orientations adopted for regulating land uses in the vicinity of hazardous establishments in these countries; by applying it, the study demonstrates that different cultural attitudes towards uncertainty may be a determinant factor in the approaches to and the regulation of the matter of hazardous facility siting. In the conclusions, the regulatory as well as ethical implications of this finding are discussed.  相似文献

Romanians were exposed in the last century to a range of natural or man-made disasters, mainly earthquakes and floods. The transition of the country from a Communist authoritarian pattern of emergency preparedness to a democratically civilian emergency system challenges the assessment of emergency preparedness and adds more complexity in designing a better and efficient system. The aim of this paper is to briefly describe the risks and institutions dealing with disasters, to assess the emergency preparedness, the uses of Knowledge Management Systems and Foresight Methodology approaches and to discover the shortcomings of the Romanian Emergency System. The empirical study designed as a reality check focuses on the perception of the local leaders of the emergency system regarding the most probable risks, and the uses and utility of long term strategic planning and foresight methodologies, using the Delphi technique. Lessons drawn from the Romanian transition could provide an interesting case study for other emerging democracies.  相似文献

The rapid pace of technological innovation in the semiconductor manufacturing industry has necessitated the acquisition of competitive advantage from strategic technology planning. The vital requisite for this is well-timed investment including the replacement of old equipment with advanced new equipment. In such investment, selecting the appropriate semiconductor manufacturing equipment from the appropriate supplier is a key factor for successful technology planning. Therefore, equipment supplier selection should be taken into account in the technology planning of semiconductor manufacturing companies. One of the most widely used tools for technology planning is the technology roadmap (TRM). However, conventional TRMs have not considered the task of supplier selection. To address this limitation, this study proposes an extended, four-layered TRM that adds the layer of equipment supplier to the conventional layers of market, product, and technology. The equipment suppliers to be included in the new layer are selected from the supplier portfolio matrix composed of two performance axes: supplier performance and equipment performance. The candidates of equipment suppliers are placed on the supplier portfolio matrix according to the values of two axes determined by evaluation using the analytic hierarchy process (AHP). The proposed TRM is expected to be useful for technology planning by adding a consideration for equipment supplier selection in semiconductor manufacturing companies.  相似文献

While policy-makers understand the vast benefits of publicly funded and not-for-profit research, governance practitioners have the difficult task of defining processes that can best foster high performance for science and technology (S&T) labs not primarily driven by profits. This qualitative study develops a new taxonomy based on two dimensions, the nature of the funding relationship between the parent organisation and the S&T lab and the degree of interdependence between the lab's research units. We discuss the dynamics uncovered for each of the four archetypes with illustrative cases and argue that high-performance governance of S&T labs requires an internal coherence linking the processes of planning, funding and performance evaluation.  相似文献
