Public participation in transparent decisionmaking has been proposed as a panacea for environmental protection. Bargaining theory suggests drawbacks to transparency such as hardening of attitudes and intransigence. Yet achievement of consensus on environmental values for integrated water resource management demands public involvement. Historical study of attempts to prevent reservoir construction in upland valleys designated for protection of nature suggests that 'closed-door' bargaining proved more effective for environmentalists than open, public debate. Records now open for analysis of disputes over Teesdale and Farndale, 1950–1970, allow comparisons to be made between behind-the-scenes deliberations and 'open-door' public discussion. The ambition of progressing from public participation to devolution of environmental decisionmaking and responsibility to the local scale demands more conceptualization of the process of decisionmaking on water resource development. 相似文献

古村落社区旅游参与度及影响因素——西递、宏村、南屏比较研究 总被引:2,自引:0,他引:2
以社区家庭为视角,建立基于利益导向的社区旅游参与水平测度指标,以皖南古村落西递、宏村、南屏为实证研究对象,揭示了古村落社区旅游参与度异同及其影响机理。研究结果表明:① 古村落内部、古村落之间的旅游参与度均有不同程度的差异,归因为家庭微观因子与社区中观因子交互作用所致。② 通过家庭微观因子对家庭人均旅游收入影响的通径系数分析,得出三个景区相应的直接通径系数和间接通径系数,发现古村落家庭微观因子的影响方向趋同而影响程度分异,与问卷调查结果分析的一致性也显示了该方法的较强解释力和潜在应用价值。③ 提高古村落社区旅游参与整体水平、缓解参与度空间差异的根本途径在于"让利于民",增强社区分利能力,政府在其中扮演着重要的引导角色。 相似文献

在区分地方饮食与传统饮食概念的基础上,选择宏村传统饮食臭鳜鱼作为研究对象,通过对就餐环境、服务、食物3个原真性维度和满意度与行为意向2个维度,构建Amos结构方程模型,探究游客对传统饮食文化的原真性感知及其对旅游地就餐满意度和行为意向的影响。结果显示,3个维度的原真性均对满意度呈显著、直接、正向影响,对行为意向呈显著、间接、正向影响;其中,环境原真性对就餐满意度影响最大,其次为服务原真性,最后为食物原真性。研究认为,即使体验对象是与原真性关联紧密的传统饮食,大众游客仍更关注整体就餐环境和服务氛围,食物本身对满意度的影响最低。游客需求引发传统饮食文化舞台化重塑,并呈现“去传统化”与“去地方化”特征,旅游地饮食文化塑造对环境的关注大于食物,但当地居民更加关注食物本身的口味,主客关注差异和食物生产过程的游客需求导向引发当地居民对舞台化饮食的认同度降低。未来旅游地要充分考虑传统饮食的特殊性,重塑让游客与本地居民更加满意的饮食文化。 相似文献

Emerging approaches to environmental governance require a greater level of community participation than did previous approaches in which these responsibilities largely rested with government agencies. There is consequently a need for increased engagement with NRM among a broad community sector. This paper examines initiatives by two prominent government agencies, the Murray–Darling Basin Commission (MDBC) and the National Museum of Australia (NMA), to engage school children from regional communities using education programs that focus on place and environmental health. We focus on the MDBC's International Riverhealth Conference held in Mildura in 2003 and the associated Murray–Darling Basin TalkBack Classroom sponsored by the NMA and the Parliamentary Education Office (PEO). We explore how key themes of local scale, place-based identities, youth voice and critical engagement are developed in these programs and consider how they relate to the environmental agency of children. We then reflect on the potential for the kinds of environmental agency promoted through these programs to help build the capacity of local communities to progress larger goals of environmental restoration and sustainability in the Murray–Darling Basin. The evaluation research reported here forms part of the Committing to Place research project, an Australian Research Council Linkage grant involving the University of Tasmania, the National Museum of Australia and the Murray–Darling Basin Commission. 相似文献

冰雪旅游是推动冰雪经济与旅游产业高质量融合发展的重要途径,现已成为文旅产业中最具潜力的领域之一。然而在全球气候变化的影响下,冰雪旅游发展面临严峻挑战。文章以北京市为例,运用结构方程模型对冰雪旅游情境中城市居民的气候变化感知、感知价值、旅游意向和环境责任行为等变量间的影响关系及其形成机制进行分析。研究发现:(1)气候变化感知分为气候变化表征和气候变化风险两个维度,且两者显著正向影响冰雪旅游感知价值。同时,气候变化风险显著正向影响旅游者环境责任行为。(2)冰雪旅游感知价值显著正向影响冰雪旅游意向和环境责任行为。(3)冰雪旅游意向显著正向影响环境责任行为。(4)旅游经历在气候变化感知对冰雪旅游意向和环境责任行为的影响关系中具有显著的正向调节作用。本研究对厘清冰雪旅游情境下气候变化感知对游客环境责任行为的复杂影响机理具有重要的理论价值,同时也能够在一定程度上为相关部门把握“后冬奥”黄金机遇,推动冰雪旅游高质量发展提供决策参考。 相似文献

Marine Stewardship Council (MSC) certification is a market-based incentive program recognizing well-managed fisheries. Currently, four Argentine fisheries are involved in the MSC program. Using in-depth, semi-structured interviews with fishery stakeholders, the study surveys their perceptions regarding MSC certification. MSC certification is positively perceived because stakeholders focus on knowledge of the process. Most respondents consider certification as encouraging effective fishery stakeholders’ participation: access to information, increased communication, and reaching consensus. Market/political/social realities will prove whether a more intense participation of Argentine fisheries in the certification initiative is useful. Because some markets in the EU and USA are demanding MSC certified products, there is a need to work towards a governance structure that helps link certification with policy market outcomes to ensure exportation of Argentine fish. MSC certification may suggest improved management of participatory bottom-up planning. This bottom-up approach provides an opportunity to establish feedback mechanisms and organizational changes. 相似文献

Salmon fishing used to be the primary source of income in many rural areas of Arkhangelsk oblast in northwest Russia. People who settled in the area received a name Pomory, from Russian po moriu, meaning by sea, because their subsistence activities became marine fishing and hunting and seafaring. Local fisheries have undergone significant changes as post-Soviet Russia embraced the market economy and the state introduced fishing concessions. The current Russian law only allows fishing for salmon through officially registered recreational or commercial fisheries. Both these options are often either unavailable or unaffordable to rural dwellers, which leaves them with limited or no legal access to their traditional salmon fisheries. There has been a growing concern for protecting communities’ fishing rights among wider society in Arkhangelsk oblast. City activists promoted Pomory identity and appealed to the Russian government to grant Pomory an indigenous status to secure their access to fisheries. Although Pomor activism did not reach most of its proclaimed goals, it has contributed to promoting the image of Arkhangelsk oblast as a homeland to Pomor fishing. This image has played an important part in what Arkhangelsk authorities have called socially-oriented fisheries management. Officials have made good attempts to better accommodate rural communities’ access to fishing resources. Yet, these attempts have failed to include fishermen as active participants in the process. This paper looks at constraints on community participation in fisheries management in Russia. It considers both historical and contemporary reasons for the low participation of local community in fisheries management. 相似文献
