The prioritization of natural-historical based ecotourism strategies with multiple-criteria decision analysis in ancient UNESCO city: Iznik-Bursa case

Ecotourism contains the integration from ecological integrity and economic benefits to environmental and historically sensitive areas. One of the major keys of ecotourism-planning strategies is to ensure the sustainability of unique natural and cultural resources by a balance strategy between protection and use. It causes both the increase of the ecotourism awareness of local people and visitors and the decrease of the environmental problems and visitor pressures on the landscape resources of potential ecotourism areas. For this reason, the study presents the example of Iznik which is an ancient Greek, Roman, Byzantine, and Ottoman city of Nicaea with its lake, historical walls and gates, churches and early-period mosques, ceramic tiles, and agricultural activities on the southeast of Marmara Region, Turkey. It has been declared to have a different protected area status. However, the number of unsuitable management and uncontrolled economic activities has caused damage to sensitive landscape values. The aim of this research is to define ecotourism criteria for Iznik and it offers ecotourism strategies for the sustainability of sensitive landscape areas. Fieldwork, field observation, interviews and survey study with integrated multiple-criteria decision analysis and strengths-weakness-opportunities-threats (SWOT) analysis conducted with locals, tourists and experts were performed for this purpose. According to the results, among the 4 main and 15 sub-criteria of ecotourism to be in UNESCO Tentative List, the opportunity for ecotourism-planning strategy was found as the highest priority ranking. This research proposes a framework by using a priority-ranking method for the development of ecotourism strategies in the town.

Relevance of crowding effects in a coastal National Park in Germany: results from a case study on Hamburger Hallig

Coastal environments are popular sites for tourism and faced with an increasing recreational demand. Most of European coastal areas attract numerous visitors annually. In recreation research this management problem can be described in terms of carrying capacity which expresses the ability of a site or region to absorb recreational use without deterioration of natural resources and the quality of the visitor experience. As social aspects of recreation in Europe still have received little attention, the purpose of this study is to examine the applicability of the concept of social carrying capacity in a German coastal national park. The article addresses if the relationship between perceived visitor encounters, crowding perception and visitor characteristics is applicable by using data from an on-site survey (N?=?509) of visitors conducted on Hamburger Hallig, Germany. It examines whether effects of overcrowding are measurable on a popular daytrip destination with established approaches. Results demonstrate that visitors to Hamburger Hallig are characterised by a heterogeneous visitor composition of local residents and domestic tourists with different motivations and who mainly visited the area for hiking or cycling. Study findings show that valuation for reported encounters and perceived crowding differed substantially among origin of visitors and sampling dates. All in all, respondents report a high level of encounter with others and in contrast a very low level of perceived crowding.

基于重金属污染的耕地生态承载力改进模型研究

将耕地重金属污染引入耕地生态足迹研究中,对传统耕地生态承载力模型进行了改进,并以江苏省为例进行实证研究.结果表明,运用改进的生态承载力模型计算所得2005年江苏省人均耕地生态承载力为0.127 hm2,比传统模型计算结果0.134 hm2小;人均耕地生态赤字为0.067 hm2,比传统模型计算结果0.060 hm2大;耕地生态可持续指数为0.39,比传统模型计算结果0.41小,但2种模型计算方式下耕地利用均属于弱不可持续状态.与传统模型计算结果相比,改进模型所得结果能够反映江苏省耕地利用的实际情况,以及重金属污染对江苏耕地可持续利用所产生的负面影响.     

Using a social–ecological framework to inform the implementation of conservation plans

One of the key determinants of success in biodiversity conservation is how well conservation planning decisions account for the social system in which actions are to be implemented. Understanding elements of how the social and ecological systems interact can help identify opportunities for implementation. Utilizing data from a large‐scale conservation initiative in southwestern of Australia, we explored how a social–ecological system framework can be applied to identify how social and ecological factors interact to influence the opportunities for conservation. Using data from semistructured interviews, an online survey, and publicly available data, we developed a conceptual model of the social–ecological system associated with the conservation of the Fitz‐Stirling region. We used this model to identify the relevant variables (remnants of vegetation, stakeholder presence, collaboration between stakeholders, and their scale of management) that affect the implementation of conservation actions in the region. We combined measures for these variables to ascertain how areas associated with different levels of ecological importance coincided with areas associated with different levels of stakeholder presence, stakeholder collaboration, and scales of management. We identified areas that could benefit from different implementation strategies, from those suitable for immediate conservation action to areas requiring implementation over the long term to increase on‐the‐ground capacity and identify mechanisms to incentivize implementation. The application of a social–ecological framework can help conservation planners and practitioners facilitate the integration of ecological and social data to inform the translation of priorities for action into implementation strategies that account for the complexities of conservation problems in a focused way.

西藏生态整体性水平测度

为了探讨资源-环境双重约束下地处我国生态环境脆弱区的西藏的生态整体性特征,利用生态环境质量指数和生态现代化指数（EMI）对地处我国西南边陲的西藏地区的生态现代化水平进行了分析。结果表明：全球生态现代化水平在区域之间存在比较明显的空间分异。2004年西藏生态现代化指数为50,在全国排名为3位,较2000年的排名16位有了明显的提高。生态进步指数、经济生态化指数好于其他4个少数民族地区,但社会生态化指数落后于其他4个少数民族地区,人均SO2排放与新疆、广西相同,但高于内蒙古和宁夏;1980—2007年西藏现代化程度虽然有所提升,但远低于世界平均水平和中等发达国家以及我国平均水平和其他4个少数民族地区;1996—2007年西藏区域环境水平呈＂W＂型变动态势。资源转化率和水污染指数呈＂N＂型不稳定变动,生态保护指数和环境治理指数呈剧烈变动,生态脆弱性和环境支持系统的不稳定性没有明显改观。因此,西藏应立足地缘和资源优势,充分考虑西藏生态地域、生态系统服务功能、生态资产、生态敏感性以及人类活动对生态环境胁迫等要素的综合影响,依据青藏高原高寒生态大区和高寒草甸生态区、青藏高原高山草原、高寒草甸生态地区生态区划,发展人工设计生态方案的生态重建途径。建立严格的生态补偿制度,逐步提升生态现代化水平。     

Evaluating eco-sustainability and its spatial variability in tourism areas: a case study in Lijiang County,China

Studying eco-sustainability of tourism areas is part of sustainable development research. In tourism areas, the ecosystem comprises both the environment and the human system. The environmental system is basically physical, whereas the human system, consisting of both tourists and residents, is the dominant factor driving ecosystem change. If the combined influence of tourists and residents exceeds the carrying capacity of the environment, which is the ecological threshold of eco-sustainability in the tourism area, then the structure, function and stability of the environment will degenerate. Hence, eco-sustainability assessment of tourism areas should be based on analyses of the relationship between the influence of tourists and residents on the environment and the environmental carrying capacity. Using ecological footprint and tourism ecological footprint models, we developed and applied a synthetic assessment index system for eco-sustainability of tourism areas in Lijiang County, Yunnan Province, China, to conduct a quantitative spatial assessment for 2001. The eco-sustainability of Lijiang was high, with a harmonious relationship between regional socioeconomic development and the ecological environment. There were significant spatial differences in eco-sustainability among 24 towns in the region because of spatial heterogeneity in socioeconomic status, tourism development and environmental elements.     

Pricing Policy for Tourism in Protected Areas: Lessons from Komodo National Park, Indonesia

Abstract: Protected areas are under increasing pressure to provide economic justification for their existence, particularly in developing countries where demand for land and natural resources is high. Nature-based tourism offers a mechanism to generate substantial benefits from protected areas for both governments and local communities, and ecotourism is increasingly promoted as a sustainable use of protected areas. The extent to which ecotourism offsets the costs of a protected area has rarely been examined. We used financial data from Komodo National Park, Indonesia, and a willingness-to-pay questionnaire of independent visitors to (1) examine the financial contribution of tourism in offsetting the costs of tourism and wider management and (2) assess the effect of hypothetical fee increases on park revenues, visitation patterns, and local economies. Although only 6.9% of park management costs were recovered, visitors were willing to pay over 10 times the current entrance fee, indicating a substantial potential for increased revenue. The potential negative effect of large fee increases on visitor numbers and the resultant effect on local economic benefits from tourism may limit the extent to which greater financial benefits from Komodo National Park (KNP) can be realized. Our results suggest that a moderate, tiered increase in entrance fees is most appropriate, and that partial revenue retention by KNP would help demonstrate the conservation value of tourism to both visitors and managers and has the potential to increase visitors' willingness to pay.     

Quantitative SWOT analysis for prioritizing ecotourism-planning decisions in protected areas: Igneada case

As environmental problems and pressures on natural resources escalate, awareness building and efforts to protect natural areas have also became a major goal to ensure sustainability. Ecotourism is one of the major activities to protect natural and cultural resources, while also providing economic benefits to both local people and government. Successful ecotourism planning is a function of establishing sound goals and criteria. In this paper, we have presented the example of Igneada, Turkey, as a case to elaborate this point. Igneada a coastal town, located on the north-west Black Sea region of Turkey, was declared a national park in 2007. The park is well known for its longos forests (flooded), lagoons, endemic and endangered species, and wildlife. However, currently, unsustainable economic activities, overgrazing, and urbanization cause threats to its sensitive ecosystems. Promoting ecotourism is a sustainable approach to balance economic, social, and environmental aspects in the development of Igneada.

The aim of this study is to define a set of ecotourism criteria and propose an ecotourism vision for Igneada. The methodology in this research involves field observations and a strengths, weaknesses, opportunities and threats analysis with an Analytical Hierarchy Process. A survey study is conducted with both local people and experts to define a framework to generate a priority ranking for ecotourism-planning decision. The research generated 5 main criteria and 14 subcriteria, among which ‘Proposal of Igneada in Turkey’s 2023 Tourism Strategy Plan’ was the highest ranked opportunity for ecotourism planning and development in the town.     

A training model for environmental educators and interpreters employed in Greek protected areas and ecotourism settings

In Greece, environmental interpretation is in its infancy as an academic field. In particular, there are no nature guides or specific conservation objectives, and no professional training for non-formal environmental educators and/or interpreters. In view of the United Nations Decade of Education for Sustainable Development, this paper develops and recommends a training model for environmental educator/interpreter guides in protected areas and sensitive ecotourism settings in Greece. An investigation was undertaken into training programmes in developed and less developed ecotourism countries, where environmental interpretation is practiced in the sustainable management of sensitive areas. The proposed model is based mainly on interpretive training programmes of other developed and less developed countries. This model introduces the art of environmental interpretation as a form of non-formal environmental education, integrated in strategic communication in protected areas and sensitive ecotourism areas in Greece. The developed model takes into consideration the special social settings and biophysical environments of Greece. Moreover, a professional environmental interpreter group is recommended to support the role of management authorities in protected areas.     

Contingent valuation of ecotourism development in country parks in the urban shadow

To optimise the use and management of Hong Kong's country parks, ecotourism has recently been promoted by the government and echoed by the leisure sector. Visitors' valuation of ecotourism development hitherto remains scant and could add a new dimension to the knowledge and management base. This study estimated the potential value of ecotourism development using the contingent valuation method (CVM). A total of 613 visitors in three country parks were interviewed. The results showed that the bid amounts and the motives to experience and learn more about nature were significant predictors of willingness-to-pay (WTP). The mean and median WTP were, respectively, HK$101.1 and HK$85.0 annually, varying slightly between parks. The differences were associated with the special ecological and accessibility characteristics of individual parks. The results could justify financial support from the government for ecotourism development and associated nature conservation endeavours and promote the incorporation of natural resource valuation in formulation of public policies in Hong Kong and other developing regions.     

Geographical analysis of tourism sites in Andaman Archipelago (India) and ecotourism development for Smith Island of North Andaman

This paper applies the nearest-neighbour analysis to analyse the clustering of tourist attractions in Andaman region and suggests ecotourism development for Smith Island of North Andaman using remote sensing techniques. The results indicated that present tourism sites are distributed in clusters in three regions (Port Blair, Mayabunder and Diglipur). To avoid concentration of tourism sites and population pressure in one particular area, there is a need to promote tourism to other locations as well. The study provided suggestions for ecotourism development in Smith Island after analysing its various ecological features to support the Andaman Administration’s vision to promote ecotourism.

Calculating ecological carrying capacity of shellfish aquaculture using mass-balance modeling: Narragansett Bay, Rhode Island

Increasing growth in the aquaculture industry demands ecosystem-based techniques for management if that growth is to be ecologically sustainable and promote equity among users of the ecosystems in which it occurs. Models of carrying capacity can be used to responsibly limit the growth of aquaculture in increasingly crowded coastal areas. Narragansett Bay, Rhode Island, USA is one such crowded coastal region experiencing a rapid increase in bivalve aquaculture. An ecosystem mass-balance model was used to calculate the ecological carrying capacity of bivalve aquaculture. Cultured oyster biomass is currently at 0.47 t km⁻² and could be increased 625 times without exceeding the ecological carrying capacity of 297 t km⁻². This translates to approximately 38,950 t of harvested cultured oysters annually which is 4 times the total estimated annual harvest of finfish. This potential for growth is due to the high primary productivity and large energy throughput to detritus of this ecosystem. Shellfish aquaculture has potential for continued growth and is unlikely to become food limited due, in part, to the large detritus pool.     

城市生态可持续性的内涵及其支持系统评价指标体系研究

构建城市生态可持续性支持系统评价模型并对其发展水平进行综合评价,是城市生态可持续性从理论研究阶段进入可操作的实际应用阶段的重要步骤。针对城市生态可持续性基本内涵,根据＂承载力-支持力-吸引力-延续力-发展力＂（CSAED）模型框架,构建城市生态可持续性支持系统的评价指标体系,以泛长株潭地区为例,分析了该区域各地市在生态环境有效改善、资源能源集约利用、社会民生和谐进步、经济高效公平增长、人口质量综合提升、政策和制度调整与完善等方面的基本情况与提升方向。评价结果表明：泛长株潭地区大部分城市生态环境有效改善水平、资源能源集约利用效率、社会民生进步程度以及经济高效公平增长水平都普遍偏低,这意味着当前该区域亟需解决城市生态承载力不够强、环境容量有限、产业结构仍待升级、就业结构不优及公共服务不足等区域经济社会发展不协调问题,以维持区域城市生态可持续性。
