‘Whether protectionism spreads, imposing major harm on the world economy, depends on three factors: the costs and benefits of trade for domestic political actors; these actors’ access to and control over the process of government; and the extent to which international commitments and obligations to trade policy are viewed as binding by national governments’ —Costs and Benefits of Protection (Paris: OECD Secretariat, 1985) 相似文献

Traditional Management Systems, Poverty and Change in the Arid Zone Fisheries of Northern Nigeria 总被引:2,自引:1,他引:2
This paper, based on fieldwork results, explores traditional management systems (TMS) in the arid zone fisheries of north-eastern Nigeria with particular reference to their impact on rural poverty. The first section provides a historical background by tracing the evolution of the TMS since the nineteenth century, with reference to government policy on fisheries management and poverty alleviation. The second gives an overview of TMS, including definitions, distribution, principal objectives, regulatory mechanisms and the impact of TMS on the performance of the fisheries and on the livelihoods of rural people. The third considers the perceptions and attitudes of the fishing communities with regards to the fisheries and TMS. The paper concludes, paradoxically, that while TMS provide a basis for the sustainable livelihoods of many fishing people, they also reflect and enforce the social positions of the rich and powerful members of society who oversee them, at the expense of the poor. In the future, poverty alleviation in fisheries will need to incorporate both sectoral and non-sectoral strategies – dealing with the existing 'paradox of TMS' by encouraging appropriate institutional changes and community development, and recognizing the importance of employment creation in other sectors of the economy as a source of alternative income. 相似文献

Many wildlife tourist attractions (WTAs) have negative impacts on animal welfare and species conservation. In the absence of regulation, raising standards requires tourists to create market pressure by choosing to attend WTAs with benefits for wildlife. We surveyed respondents from five countries – China, Australia, Canada, UK, and USA – to quantify how attitudes to captive animals, and towards WTAs’ outputs and standards, may vary with nationality. Our aim was to provide a firm basis for behaviour change interventions to alter current patterns of tourist consumption of WTAs. All respondents agreed on the importance of conservation and animal welfare, but Chinese respondents were twice as likely to believe that WTAs would not be allowed to exist if they were bad for animals, and that WTAs’ promotional materials were reliable indicators of welfare and conservation standards. These findings indicate Chinese respondents had fundamentally similar attitudes to those from the other countries, but differed in how those attitudes were likely to be applied. Chinese tourists may experience more barriers to aligning their actions with their values with respect to WTAs. Removing these barriers may require information campaigns to highlight the lack of regulation, and the unreliability of some WTAs’ promotional materials and tourists’ reviews. 相似文献

Tourist preferences for ecotourism in rural communities adjacent to Kruger National Park: A choice experiment approach 总被引:1,自引:0,他引:1
This paper analyses the potential for development of ecotourism in rural communities adjacent to Kruger National Park (KNP) in South Africa. We determine preferences of tourists, according to origin and income levels, for ecotourism and their marginal willingness to pay (MWTP) for three ecotourism attributes: village accommodation, village tours and visits to crafts markets. Data were collected from 319 tourists through choice experiments, and analyzed using a conditional probit model. Findings indicate reluctance on the part of all tourists to use accommodation facilities outside KNP, but interest to purchase village tours and visit village-based craft markets. MWTP was negative for accommodation for all income groups, but positive for village tours and crafts markets. Among international and high income groups of tourists, tourists were willing to pay much higher fees than proposed by communities. These findings suggest the potential for development of some limited ecotourism services in villages adjacent to KNP. 相似文献

Appreciative inquiry is a participatory research method based on positive psychology. Founded upon grounded theory and the social constructivist paradigm, appreciative inquiry is a simple, effective, and epistemologically sound tool to understand the rural population’s knowledge, needs, and priorities without alienating them from research. Based on the study conducted to comprehend the interrelationships among conservation, livelihood, and tourism development in three rural communities located in the vicinity of Chitwan National Park, Nepal, this study argues that appreciative inquiry can be a useful tool for conducting tourism research in rural communities. This study employs five steps, including grounding, discovery, dream, design, and destiny. 相似文献
