Factors for success in rural tourism tourism development

Since the 1970s,economic restructuring and farm crisis have reduced rural communities' economic development options, making older development strategies less viable and forcing many to look for nontraditional ways to sustain themselves. One of the most popular nontraditional rural development strategies has been tourism and its associated entrepreneurship rural development strategies has been tourism and its associated entrepreneurship opportunities because of

tourism's ability to bring in dollars and to generate jobs and support retail growth. The purpose of this study was to identify and examine those factors that have helped rural communities successfully develop tourism and its entrepreneurship opportunities. Several focus groups were conducted with local businesspersons and leaders in six rural Illinois communities. The results clearly demonstrate the importance of the community approach to tourism development and that rural tourism development and entrepreneurship cannot work without the participation and collaboration of businesspersons directly and indirectly involved in tourism.

Since the 1970s, economic restructuring and the farm crisis have severely reduced rural communities’economic opportunities.Economic restructuring has caused a loss of rural manufacturing plants and many jobs. The 1980s farm crisis in the Midwest also led to a decline in the numbers of farmers and restructured farm ownership, forcing some farm families to augment their incomes with off-farm jobs, to depart farming, or to declare bankruptcy. The farm crisis and the loss of manufacturing jobs had substantial ripple effects in rural communities. As rural joblessness rates rose above urban levels, real income growth stagnated in rural areas (Sears and Reid 1992). Many stores and agribusinesses disappeared from small rural towns. Not surprisingly, a 1992 statewide survey in Illinois found that 39% of rural residents perceived their economic prospects as worsening (Walzer 1993).

These changes limited rural communities’economic development options, making older development strategies such as manufacturing less viable and forcing many to look for nontraditional ways to sustain themselves . One of the most popular nontraditional rural development

strategies has been tourism and its associated entrepreneurship opportunities (Edgell and Harbaugh 1993; Luloff et al. 1994). Rural areas have a special appeal to tourists because of the mystique associated with rural areas and their distinct cultural, historic, ethnic, and geographic characteristics (Edgell and Harbaugh 1993). Rural tourism also is less costly and easier to establish than other rural economic development strategies such as manufacturing. Rural tourism can be development strategies such as manufacturing. Rural tourism can be developed locally with participation from local government and small businesses, and its development is not necessarily dependent on outside firms or companies. Although tourism can be expensive to develop in certain cases (e.g., large resort areas) or can involve large firms and chains, rural tourism can be developed with relatively little investment credit, training, and capital. Hence, rural tourism can be less costly to develop as compared to other economic development strategies; additionally, rural tourism need not involve dependency on outside firms and their decisions on whether they want to be in an area. Rural tourism provides a base for these small businesses that might not otherwise be in rural communities because of their small populations. Tourism particularly helps two types of small businesses in rural areas—those directly involved in tourism (e.g., attractions and hotels/motels) and those indirectly involved in tourism (e.g., gas stations and grocery stores). Additionally, rural tourism works well with existing rural enterprises such as farms (e.g., U-Pick farms) and can generate important secondary income for farm households (Oppermann 1996).Nonetheless, rural tourism remains one of the few viable economic options for rural communities .Like other economic development strategies, rural tourism requires several components to be successful.

Tourism development involves(1) attractions: the natural and manmade features both within and adjacent to a community; (2) promotion:

the marketing of a community and its tourism attractions to potential tourists;(3) tourism infrastructure: access facilities (roads, airports, trains, and buses),water and power services, parking, signs, and recreation facilities; (4) services: lodging, restaurants, and the various retail businesses needed to take care of tourists’ needs; (5) hospitality: how tourists are treated by both community residents and employees in tourism businesses and attractions (Gunn 1988). Left out of this list are tourism entrepreneurs and their role in fostering these components.While the above components and a community’s assets are clearly important to tourism development, only the widespread participation and contribution of rural tourism entrepreneurs can ensure a broad-based foundation for successful tourism development. A research literature has emerged on how to best facilitate the development of tourism. One view, drawing heavily on the economic literature, argues that tourism and its associated entrepreneurship opportunities are best developed by helping and creating individuals businesses and then letting them compete in the marketplace for a review and description of this view). This view, however, has been critiqued because (1) it views tourism and tourism-related businesses as isolated from the larger community and its issues;(2) it does not recognize the interdependence of the various sectors and actors involved in tourism; and (3)most small tourism business, especially those in rural areas, do not have the individual resources to promote either themselves or the community as a tourist product (Gunn 1988; Murphy 1985; Palmer and Bejou 1995).Opposing this view is the community approach to tourism development and entrepreneurship (Murphy 1985). As its name implies, the approach argues that tourism is a community product and that, along with entrepreneurial skills and the presence of tourist businesses, it is also necessary to have the community and local capabilities (e.g., local leadership and formal and informal networks)

directly involved in tourism development and promotion effort (Murphy 1985). While the community approach may be an effective way to develop and promote tourism, creating the necessary intercommunity cooperation and collaboration is a complex and difficult process. Businesses are asked to share resources while simultaneously competing. Local governments may see collaborating to develop tourism as risky, or they may be worried about losing control over local decision making (Huang and Stewart 1996; Jamal and Getz 1995). Because of these problems, research on collaboration and those factors that allow for community development of tourism is needed . The purpose of the present study is to identify and examine those factors that help rural communities successfully develop tourism and its entrepreneurship opportunities. The present study makes an additional contribution to the research literature by including rural tourism entrepreneurs, an overlooked group in rural tourism research (Stokowski 1990).

20世纪70年代以来,经济体制的改革和农业危机使得农村社区经济发展的选择减少,同时促使老年人发展战略可行性降低,迫使人们去寻找非传统的方式来维持生计。乡村旅游及其相关产业发展策略因其为社会带来的资金收入、增加就业机会及支持零售增长的功能而成为时下最流行的非传统农业发展策略之一。本研究的目的是确定和审查这些因素,帮助农村社区成功走上发展旅游业的创业道路。几个重点群体在伊利诺斯六个农村社区与当地商人和领导人进行了实验。结果清楚地表明重要的社区不是直接就是间接地参与到了乡村旅游的开发中。 20世纪70年代以来,经济体制的改革和农业危机的发生已严重阻碍了农村经济的发展,经济结构的调整导致了乡村农业生产力和就业岗位的减少。20世纪80年代在中西部发生的农业危机也导致了农民和重组制农场的减少,迫使一些农户为增加收入而参与非农工作,或离开农场,或宣布破产。农场的危机和制造工作的丢失对农村社区产生了重大的影响。随着农村失业率高于城市水平,实际的收入增长停滞在农村地区(希尔和瑞德1992)。许多商店和农业从农村小城镇消失,毫不奇怪,1992年伊利诺斯州的调查表明,39%的农村居民认为他们的经济前景将恶化(沃尔泽1993)。

这些变化限制了农村社区的经济发展方案,使旧式的发展战略例如制造业的可行性降低,并迫使许多人寻找非传统的方式来维持生活。其中最流行的非传统的农村发展战略当属旅游及其相关的创业机会(艾基尔和哈博1993;鲁洛夫等人。1994)。农村地区因其神秘独特的文化,历史,民族和地理特征而对游客产生了特殊的吸引力,(艾基尔和哈博1993)。乡村旅游比起其他的农村经济发展战略例如制造业相对来说开发成本较低且建立较容易。乡村旅游的发展可以带动制造等的发展。乡村旅游可以与其所在地的地方政府和小型企业共同发展,但它的发展并不一定依赖于外部企业或公司。虽然旅游在某些中心地区的发展需要较大的成本投入或者涉及大公司和连锁企业,但是乡村旅游却可以在较少的信贷投资,人员培训和少量资本情况下得到发展。因此,乡村旅游相比较其他的经济发展策略可以在较少投入花费情况下得以发展。此外,乡村旅游不需要涉及依赖外部公司以及他们是否在同一区域的决定。乡村旅游为一些因人口少而可能无法留在农村社区的小公司提供了保障。旅游特别有助于两种类型的小型企业,在农村地区直接参与(例如,旅游景点和酒店、汽车旅馆)和间接参与旅游的企业(例如,加油站和杂货店)。此外,乡村旅游与现有的乡镇企业如农场(例如,采场)发展较好并且可以为家庭农场产生第二收入(奥普曼1996)。尽管有这些好处,其可行性作为一个经济发展战略,乡村旅游,在一些农村地区业有缺点(luloff 等人。1994·1989)。如农村制造,它可以使得农村社区之间互相竞争。旅游业的就业,像许多其他服务部门,仍然是美国最低工资支付阶梯(1989)。旅游及和它相关的工作的生产利润往往是季节性的,一年中只有部分。然而,乡村旅游对于农村社区仍然是少数可行的经济选择。像其他的经济发展战略一样,乡村旅游的成功需要若干部分的组成。

旅游开发涉及(1)景点:社区内自然和人为的功能分区;(2)推广:一个社区和旅游景点的潜在游客的营销;(3)旅游设施:设施(公路,机场,火车,公共汽车),水和电力服务,停车场,标志,及娱乐设施;(4)服务:住宿,餐饮,和各种零售企业需要照顾的游客的需要;(5)餐饮:游客在旅游企业和旅游景点被社区居民和雇员如何对待(甘1988)。除上述列表外,还有旅游企业家促进了旅游的开发。虽然上述成分和社区资产对于旅游开发是十分重要的,只有广泛的参与和贡献,乡村旅游企业家确保广泛的基础,乡村旅游才能成功的

发展。研究文学出现了关于如何最好地促进旅游业的发展的研究。一个绘制大量的经济试图的文献,认为对旅游业及其相关的创业机会最好的帮助是建立个人企业,让他们在市场上竞争这一观点,但是,一直精益求精,因为它把旅游业及相关企业及其问题作为孤立的大社区;它不承认相互依存,不同的部门和行动者共同参与旅游;(6)多数旅游小企业,特别是在农村地区,没有资源,实现自身或社会旅游产品的开发(甘1988;·1985;帕和bejou1995)。反对这一观点的是社区旅游业发展的企业家(莫非1985)。顾名思义,该方法认为,旅游是一个社区和产品,随着旅游企业创业技能的发展,以及当地社区(例如,当地的领导和正式或非正式网络)直接参与旅游的开发和促销的努力(莫非1985)。而社区的办法可能是一种有效的方式,推动旅游业的发展,创造了必要的共同合作,合作是一个复杂而艰难的过程。企业资源共享的同时,也有竞争的要求。地方政府可以看到合作发展旅游业是有风险的,或者他们可能担心失去地方决策的控制(黄和斯图尔特1996;贾马尔和盖茨1995)。了解这些问题,合作研究这些因素,对于社区旅游业的发展是必要的。本研究的目的是确定和审查这些因素,帮助农村社区成功发展旅游业,创造创业机会。本研究额外进行了对在乡村旅游发展中的乡村旅游企业家,一个被忽视的群体的研究(斯托科夫斯基1990)。

Rural Tourism and Economic Development

原文正文:Tourism is a popular economic development strategy. The author reviews three diverse books that study tourism from various social science perspectives——economic, sociological, psychological, and anthropological. Ryan’s book is multidisciplinary in approach and covers all major topics of tourism; tourist experience; and marketing. Michal Smith details the negative affects of tourism development in rural areas of the southeastern United States. Finally, Valene Smith’s book presents international case studies that document cultural changes caused by tourism development. Despite their different focuses, all three books agree that tourism development has its benefits and costs and that changes to the destination areas are inevitable. Careful planning and marketing can lessen the harmful effects of tourism development.

Tourism is an increasingly popular elixir to economic rural and urban underdevelopment. Its current prominence in the array of local economic development strategies can be traced to several features of the tourism

industry. Tourism jobs are mostly low-skill jobs, which are a good fit with the job skills of many rural residents. Also, tourism has a potential for creating an export base that builds on favorable local advantages such as a pleasant climate or sites of historic or natural interest. More important, tourism strategies mesh with the current political philosophy and budget realities of minimizing government involvement and investment. The accommodations, restaurants, and entertainment activities that necessarily accompany tourism are assumed to be provided by the private sector. Critics of tourism as a development strategy cite its low-paying and dead-end jobs, its degradation of the local natural environment, and its potential corruption of local culture and customs. Further, not every jurisdiction in need of jobs and a tax base has tourism potential.

The study of tourism, like much of the economic development literature, draws from a wide range of disciplines. The forte of economists is in addressing the affects of tourism on the local economy; however, economists fail to describe who tourists are or why they travel. Anthropologists’major contribution to defining and studying tourism is in examining the impacts of tourism on local culture. Psychologists are more likely to dwell on the motives for tourism, but they ignore the impacts. Clearly, the complete definition of tourism includes the economic, social, anthropological, and psychological viewpoints. One strength of Recreational Tourism: A social Science Perspective by Chris Ryan is its multidisciplinary approach to the study of tourism. In contrast, the case studies from around the world found in Hosts and Guests: The Anthropology of Tourism, edited by Valene Smith, dwell on tourism from the perspectives of history and anthropology, with its focus on the culture affects of tourism and tourism’s role in the acculturation process.

Gee Journal 31.4457-465457?1993 (Dec) by Kluwer Academic Publishers Ecotoufism in the Small Island Caribbean Weave~ David B., Prof. Dl:, UniversiO, of Regina, Luther College, Regina, Saskatchewan $4S OA2, Canada ABSTRACT: Ecotourism-related strategies can serve to enhance the tourism industries of small Caribbean islands, which are presently dominated by a 3S (sea, sand, sun) product. In the first place, the principles of Alternative Tourism can be applied to 3S tourism in order to minimize negative environmental impacts. Secondly, diversionary ecotourism opportunities can be promoted to diversify the tourism product, thus providing a nature-oriented alternative to resort-based tourists. Thirdly, regional ecotourism, catering to ecotourists, can be fostered in mountainous interiors, peripheral islands, undeveloped coastlines, rural agricultural areas and in offshore reefs. A fourth strategy, exemplified by Dominica, entails a comprehensive ecotourism approach for destinations in which 3S tourism is undesired or unsuited. Introdactien The concept of ecotourism has attracted a considerable amount of interest among both academics and non-academics since the term was first introduced in the mid-1980s (see for example Boo t990; Goriup 1991; Lindberg 1991; Nelson, Butler and Wall 1993; Whelan 1991; Ziffer 1989). In a frequently cited definition, Ceballos-Lascurain (1988) characterizes ecotourism as Tourism that involves travelling to relatively undisturbed or uncontaminated natural areas with the specific object of studying, admiring and enjoying the scenery and its wild plants and animals, as well as any existing cultural aspects (both past and present) found in these areas. While this definition is useful in stressing the environmental orientation of ecotourism, it is clear that the term has also come to be associated with a range o f characteristics which collectively define an "alternative tourism" (AT) paradigm (Dernoi 1981; Krippendorf 1987; Singh, Theuns and Go 1989). This paradigm has emerged as an alternative to "conventional mass tourism" (CMT), which has been criticized as an often inappropriate form of tourism, especially for smaller destinations. CMT characteristics, outlined and contrasted in Tab 1 with the AT model, tend to appear during the middle and later stages of a destination's cycle of evolution (Butler 1980; Christaller 1963; Stansfield 1978). With respect to accommodations, attractions, market and economic impact, the argument can be made that ecotourism and AT are merely other names for the early "exploration" stage of the resort cycle, when relatively unspoiled areas are opened up to further tourist incursions by a few pioneer travellers. However, as pointed out by Weaver (1991), what distinguishes this "circumstantial" AT from "deliberate" AT is the lack of regulations and policies which attempt to ensure that the activity is maintained at environmentally, economically and socially sustainable levels. "Deliberate" ecotourism, the subject of this paper, is therefore very" much associated with intentions of identifying and working within the carrying capacities of a particular area, and o f discouraging the emergence of a CM T product where it is deeme d to be undesirable or inappropriate. The recent proliferation of ecotourism case studies, based largely in the underdeveloped world, is not surprising in light of deliberate ecotourism's status as the fastest growing form o f tourism (Whelan 1991). For example, Dearden (1989) and Zurick (1992) examined the p h e n o m e n o n of mountain trekking in Nepal and northern Thailand respectively, while Boo (1990), and Fennell and

人工智能的形成及其发展现状分析 冯海东 (长江大学管理学院荆州434023) 摘要:人工智能的历史并不久远,故将从人工智能的出现、形成、发展现 状及前景几个方面对其进行分析,总结其发展过程中所出现的问题,以及发展现状中的不足之处,分析其今后的发展方向。 关键词:人工智能,发展过程,现状分析,前景。 一.引言 人工智能最早是在1936年被英国的科学家图灵提出,并不为多数人所认知。 当时,他编写了一个下象棋的程序,这就是最早期的人工智能的应用。也有著名的“图灵测试”,这也是最初判断是否是人工智能的方案,因此,图灵被尊称为“人工智能之父”。人工智能从产生到发展经历了一个起伏跌宕的过程,直到目前为止,人工智能的应用技术也不是很成熟,而且存在相当的缺陷。 通过搜集的资料,将详细的介绍人工智能这个领域的具体情况,剖析其面临的挑战和未来的前景。 二.人工智能的发展历程 1. 1956年前的孕育期 (1) 从公元前伟大的哲学家亚里斯多德(Aristotle)到16世纪英国哲学家培根(F. Bacon),他们提出的形式逻辑的三段论、归纳法以及“知识就是力量”的警句,都对人类思维过程的研究产生了重要影响。 (2)17世纪德国数学家莱布尼兹(G..Leibniz)提出了万能符号和推理计算思想,为数理逻辑的产生和发展奠定了基础,播下了现代机器思维设计思想的种子。而19世纪的英国逻辑学家布尔(G. Boole)创立的布尔代数,实现了用符号语言描述人类思维活动的基本推理法则。 (3) 20世纪30年代迅速发展的数学逻辑和关于计算的新思想,使人们在计算机出现之前,就建立了计算与智能关系的概念。被誉为人工智能之父的英国天才的数学家图灵(A. Tur-ing)在1936年提出了一种理想计算机的数学模型,即图灵机之后,1946年就由美国数学家莫克利(J. Mauchly)和埃柯特(J. Echert)研制出了世界上第一台数字计算机,它为人工智能的研究奠定了不可缺少的物质基础。1950年图灵又发表了“计算机与智能”的论文,提出了著名的“图灵测试”,形象地指出什么是人工智能以及机器具有智能的标准,对人工智能的发展产生了极其深远的影响。 (4) 1934年美国神经生理学家麦克洛奇(W. McCulloch) 和匹兹(W.

Lathes Lathes are machine tools designed primarily to do turning, facing and boring, Very little turning is done on other types of machine tools, and none can do it with equal facility. Because lathes also can do drilling and reaming, their versatility permits several operations to be done with a single setup of the work piece. Consequently, more lathes of various types are used in manufacturing than any other machine tool. The essential components of a lathe are the bed, headstock assembly, tailstock assembly, and the leads crew and feed rod. The bed is the backbone of a lathe. It usually is made of well normalized or aged gray or nodular cast iron and provides s heavy, rigid frame on which all the other basic components are mounted. Two sets of parallel, longitudinal ways, inner and outer, are contained on the bed, usually on the upper side. Some makers use an inverted V-shape for all four ways, whereas others utilize one inverted V and one flat way in one or both sets, They are precision-machined to assure accuracy of alignment. On most modern lathes the way are surface-hardened to resist wear and abrasion, but precaution should be taken in operating a lathe to assure that the ways are not damaged. Any inaccuracy in them usually means that the accuracy of the entire lathe is destroyed. The headstock is mounted in a foxed position on the inner ways, usually at the left end of the bed. It provides a powered means of rotating the word at various speeds . Essentially, it consists of a hollow spindle, mounted in accurate bearings, and a set of transmission gears-similar to a truck transmission—through which the spindle can be rotated at a number of speeds. Most lathes provide from 8 to 18 speeds, usually in a geometric ratio, and on modern lathes all the speeds can be obtained merely by moving from two to four levers. An increasing trend is to provide a continuously variable speed range through electrical or mechanical drives. Because the accuracy of a lathe is greatly dependent on the spindle, it is of heavy construction and mounted in heavy bearings, usually preloaded tapered roller or ball types. The spindle has a hole extending through its length, through which long bar stock can be fed. The size of maximum size of bar stock that can be machined when the material must be fed through spindle. The tailsticd assembly consists, essentially, of three parts. A lower casting fits on the inner ways of the bed and can slide longitudinally thereon, with a means for clamping the entire assembly in any desired location, An upper casting fits on the lower one and can be moved transversely upon it, on some type of keyed ways, to permit aligning the assembly is the tailstock quill. This is a hollow steel cylinder, usually about 51 to 76mm(2to 3 inches) in diameter, that can be moved several inches longitudinally in and out of the upper casting by means of a hand wheel and screw. The size of a lathe is designated by two dimensions. The first is known as the swing. This is the maximum diameter of work that can be rotated on a lathe. It is approximately twice the distance between the line connecting the lathe centers and the nearest point on the ways, The second size dimension is the maximum distance between centers. The swing thus indicates the maximum work piece diameter that can be turned in the lathe, while the distance between centers indicates the maximum length of work piece that can be mounted between centers. Engine lathes are the type most frequently used in manufacturing. They are heavy-duty machine tools with all the components described previously and have power drive for all tool movements except on the compound rest. They commonly range in size from 305 to 610 mm(12 to 24 inches)swing and from 610 to 1219 mm(24 to 48 inches) center distances, but swings up to 1270 mm(50 inches) and center distances up

乡村旅游与可持续发展【外文翻译】

外文翻译 译文 标题:乡村旅游与可持续发展 资料来源: 亚诺什学院 - 布达佩斯经济科学大学 作者:塔玛拉拉茨 - 拉斯洛坡格左 引言 乡村旅游是旅游产业的一个部分,这在匈牙利显得尤为重要。在一个国家没有壮观的自然景观,没有海滨、高山、雨林、珍奇动物的情况下,迷人的村庄、温泉、河流和湖泊这些旅游资源可以利用起来。优美环境与当地人们传统的热情接待相结合,能够提供给游客愉快的体验,让游客在安静的环境中得到放松并且欣赏到文化景观。 一方面,乡村旅游业的发展使匈牙利旅游资源呈现多样化,使国家形象更加多姿多彩。另一方面,乡村旅游是刺激经济增长的一种手段,促进了欠发达地区的产业发展,并改善当地居民的生活水平。 如果乡村旅游要发挥其真正的作用,在某种程度上得到进一步的发展,那么在其自身发展的基础上,就要确保资源的长期可持续性发展。那么,什么是乡村旅游的可持续发展方式?如何对其可持续性进行监测来达到促进农村发展的目的?本文试图回答这些问题,并且通过提出匈牙利乡村旅游指标来了解被认为是这种类型的旅游的目前情况。 旅游业可持续发展 可持续发展的概念是由世界环境与发展委员会在1987年的布伦特兰报告中关提出来的,可持续发展定义为“发展,以满足当代人的需求又不损害子孙后代能满足自己的需要”。 旅游业是世界各地最重要的经济活动之一,1997年世界各地国际运送超过6.17亿人,年收益产生448亿美元(WTO,1998年),这是一个重要的经济力量。1996年产生生产总值3153.3亿美元,为255万人创造就业机会,参与生产应用程序。旅游业生产值占到世界10.7%的国内生产总值,766亿美元用于投资应用程序,每年都

原文: Destination brand positions of a competitive set of near-home destinations Abstract: Although the branding literature commenced during the 1940s, the first publications related to destination branding did not emerge until half a century later. A review of 74 destination branding publications by 102 authors from the first 10 years of destination branding literature (1998–2007) found at least nine potential research gaps warranting attention by researchers. In particular, there has been a lack of research examining the extent to which brand positioning campaigns have been successful in enhancing brand equity in the manner intended in the brand identity. The purpose of this paper is to report the results of an investigation of brand equity tracking for a competitive set of destinations in Queensland, Australia between 2003 and 2007. A hierarchy of consumer-based brand equity (CBBE) provided an effective means to monitor destination brand positions over time. A key implication of the results was the finding that there was no change in brand positions for any of the five destinations over the four year period. This leads to the proposition that destination position change within a competitive set will only

外文文献 RURAL TOURISM AND SUSTAINABLE DEVELOPMENT INTRODUCTION Rural tourism is a segment of the total tourist industry which is particularly important in Hungary, in a country with no spectacular natural attractions, without seaside, high mountains, rainforest or herds of exotic animals. However, its attractive cultural landscapes with small villages, thermal springs, rivers and lakes, combined with the traditional hospitality, are able to offer pleasant experiences to the kind of tourist who is looking for relaxation and recreation in a calm setting. On one hand, rural tourism development can play an important role in the diversification of the Hungarian tourist supply and in the creation of a more complex and colourful country image. On the other hand, rural tourism is not only the end, but the means to stimulate economic growth, to increase the viability of underdeveloped regions, and to improve the living standards of local populations. If rural tourism is to fulfil all these roles, it has to be developed in a way that ensures the long-term sustainability of the resources and that of the development progress itself. But what is a sustainable way of development in rural tourism ? How can sustainability be monitored and promoted in rural destinations ? This paper attempts to answer these questions by presenting the current situation of Hungarian rural tourism through indicators that are considered to be relevant for this type of tourism. SUSTAINABLE TOURISM DEVELOPMENT The concept of sustainable development was introduced by the World Commission on Environment and Development in the Brundtland Report in 1987, defining sustainable development as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs". Tourism is one of the foremost economic activities around the world, having transported more than 617 million people internationally and generated 448 billion USD in receipts in 1997 (WTO, 1998). It is a major economic force, having generated in 1996 an estimated 3,153.3 billion USD in gross output, creating employment for app. 255 million people, producing app. 10.7 per cent of world gross domestic product, investing app. 766 billion USD in new facilities
