Many programmes formally engage Australian Indigenous people in land and sea management to provide environmental services. There are also many Indigenous people who ‘look after country’ without rewards or payment because of cultural obligations. We investigated how Indigenous peoples’ mobility in and around two communities (Maningrida and Ngukurr) is affected by their formal or informal engagement in cultural and natural resource management (CNRM). Understanding factors that influence peoples’ mobility is important if essential services are to be provided to communities efficiently. We found that those providing formal CNRM were significantly less likely to stay away from settlements than those ‘looking after their country’ without payment or reward. Paying Indigenous people to engage with markets for CNRM through carbon farming or payments for environmental services (PES) schemes may alter traditional activities and reduce mobility, particularly movements away from communities that extend the time spent overnight on country. This could have both environmental and social consequences that could be managed through greater opportunities for people to engage in formal CNRM while living away from communities and greater recognition of the centrality of culture to all Indigenous CNRM, formal or otherwise.  相似文献

文化林是按照文化传统和风俗习惯来保护和管理的森林,在保护生物多样性的同时也维持了生态系统服务功能.采用半结构式访谈法调查了文化林周边村民对文化林的生态系统服务功能的认知及保护意愿,结果表明:(1)村民认为文化林提供的最重要的服务功能为固碳释养、水源涵养及美学价值,并与最满意的服务功能间存在正相关关系.最期望提高的服务功能是文化功能,例如:生态旅游,美学价值.(2)相对周边其他森林村民对文化林的资源利用较小,主要是非林木产品,平均26.3%的被访村民在文化林中获得过收入,40.6%的被访者获得山野菜、竹子、中药材、薪柴等.但90.1%被访者从其他森林中得到薪柴等林产品,开展旅游村落的村民获得林产品比例相对较小,但管护意愿相对较低.(3)村民对文化林的保护积极性较高,70.4%的被访者愿意花时间来管护森林,距文化林越近、家庭收入越高,管护意愿越高.38.9%的被访者愿意支付费用来维持服务功能不变化,距文化林越近,管护意愿越低的被访者,支付意愿越高.(4)通过了解村民对文化林的态度和认知,对我国农村森林生态系统服务功能和天然林保护具有重要意义.建议大力宣传文化林的生态系统服务功能,尤其是文化功能,并寻找替代生计提高居民收入,雇佣当地男性村民看护森林,充分利用村民的传统知识加强共管力度,完善村规民约,在今后规划中尽量将村落沿着文化林布局,积极支持对文化林的保护和发展.  相似文献

Mangroves provide valuable ecosystem services for the wellbeing of coastal communities. Assessment and valuation of these mangroves services are increasingly advocated in development and conservation decision-making. Translating the values of services into more explicit monetary terms requires understanding of stakeholder activities, socio-economic context and local organizational structure to effectively support decision-making. Based on a survey of 100 households of three villages of Sundarban in Bangladesh, mangroves services to local communities were identified and their economic values estimated. The households perceived 18 mangroves services, of which capture fisheries, fuel energy, storm protection, habitat for fish breeding and nursery grounds and aesthetic enjoyment were ranked the most important. For provisioning services, households obtained important monetary benefits annually from capture fishery (US$ 976 per ha), fuel energy (US$ 80 per ha), honey (US$ 53 per ha) and fodder (US$ 26 per ha). The average annual willingness to pay for storm protection, erosion control and habitat for fish breeding and nursery services were estimated, respectively, as US$ 13 per ha, US$ 2 per ha and US$ 9 per ha. However, unsustainable exploitation and salinity intrusion impacted the services provided by mangroves. This study provides an important insight into the services and values of mangroves for local welfare, and thus can inform policy for protection and better use of mangrove resources.  相似文献

In the midst of global species loss, Indigenous languages and culture are experiencing similar declines. Current international policies and programs advocate the involvement of local and Indigenous people in sustaining biodiversity and culture, but the anticipated benefits are not always realized or assessed. This paper draws on three objectives of current international and Australian policy to explore the biological and cultural benefits of a collaborative cross-cultural biodiversity project of Indigenous rangers and university ecologists in remote northern Australia. Policies promoting blends of biological and cultural conservation from International to national scale share the following objectives: (1) involve Indigenous Peoples in biodiversity conservation; (2) maintain and develop Indigenous knowledge and culture; and (3) recognize and promote Indigenous natural and cultural resource management and traditional knowledge. This paper reflects on the project benefits in the context of these objectives, with the aim of informing future policy and program development. Biodiversity benefits of the cross-cultural project included new public records for a relatively poorly known but species rich area that are being used to inform local Indigenous land management, as well as specimens and tissue samples with which to explore the genetic diversity and evolutionary history of the region. Cultural benefits included compiling a local field guide that contains ten different languages and engaging young people to facilitate intergenerational transfer of threatened traditional knowledge. Promotion of the work at local to national fora addressed the third objective and enhanced Indigenous involvement. We demonstrate that top-down policy directives can be implemented to deliver on-ground mutual benefits for science and Indigenous communities.  相似文献

We conducted a choice experiment for the economic valuation of benefits of components of biodiversity that are provided by the natural systems protected in the Peñuelas Lake National Reserve, located in the Mediterranean zone of Chile. The Mediterranean zone of central Chile is one of the world's 34 biodiversity hotpots. Furthermore, we estimated the economic benefits of the water supply provided by the reserve. Unlike most of the previous studies on willingness to pay (WTP) for conservation, part of the data that we produce refers to: (a) public WTP for unpopular species of fauna (an endemic amphibian currently in danger of extinction); and (b) public WTP for flora present at the Reserve (endemic orchid species). Specifically the attributes of the study were the following: existence of endemic orchid species; chances of observing animals with scenic attraction; additional protection for an endemic amphibian; and, availability of drinkable water in the future. A rate of entry to the area was incorporated to estimate WTP for additional protection for the selected attributes. WTP data were obtained from a representative sample of Chilean tourists that visit the area. Factors influencing the visitors’ WTP were also explored.Three hundred and four Chilean visitors of the reserve were randomly selected for interviews. Multinomial Logit and Random Parameter Logit models results show that visitors are willing to pay to protect the selected attributes. Marginal mean WTP/visitor for the single levels of variation of the attributes range from about $1.7 per visitor per visit for securing the existence of five species of endemic orchids to about $8.9 for guaranteeing the availability of drinkable water for 50 years. The analysis of visitors’ WTP for different levels of protection allowed an improved understanding of the sensitivity of the participants to the scope of the information provided.  相似文献

Reintroducing captive-born individuals of some extirpated flagship animal species is a helpful and remedy measure for promoting biodiversity conservation, and a successful reintroduction relies heavily on public support. However, little information is available on the factors affecting the public support for reintroduction of large carnivore species. In order to evaluate public support and willingness to pay for the Giant Panda Reintroduction Project (GPRP), we conducted 1100 interviews in August 2014 at Huaying city, Sichuan, China, close to where captive-born giant pandas (Ailuropoda melanoleuca) will be reintroduced. The results showed that local people strongly support this project and that 78.5 % of them are willing to pay an annual contribution. Per capita annual payments averaged USD31, and the potential value of donations to the GPRP in Huaying is about 11 million USD per year. Factors like interviewees’ residential area, occupation, education level, liking of wildlife, level of concern for wildlife conservation, the degree of familiarity with giant pandas, and the frequency of visiting captive giant pandas significantly affected their attitudes and willingness to pay for the project. The notion of “because I love pandas” was the main reason why respondents were willing to pay for the project; respondents’ doubts about the appropriate use of donated funds made them be unwilling to pay for the project. The results suggest that the GPRP is highly and socially acceptable amongst locals due to perceived social, economic and ecological benefits of the reintroduction. These findings clearly indicate, for the chances of reintroduction to be most socially accepted, governments should improve management and accountability when using donated funds, and create more opportunities for the public to engage with giant pandas, thereby encouraging people to become involved in conservation work benefiting conservation for the giant pandas and other endangered species.  相似文献

Hunting and habitat destruction and alteration threaten the existence of many primate species. However, the conservation of these primates has significant costs, as well as benefits, for people living alongside them. Conservation policy now recognizes that people should not suffer impoverishment from wildlife preservation and that, instead, conservation programs should make a significant contribution to alleviating rural poverty. Ethical consideration requires that local communities have greater control over natural resources, and that conservation programs contribute to these people's livelihood security. Nevertheless, this conservation on the basis of potential economic value may not protect primates adequately and may render them still vulnerable to extinction, given their sensitivity to human activities. This presents an ethical dilemma: primates have intrinsic moral value so should be conserved for their own sake, yet conservation policies should not cause harm to local human populations. This article explores ethical issues that arise when primates and people live in close proximity. [Keywords: primate conservation, ethical issues, human–wildlife conflict]  相似文献

Several treatments for obesity have received regulatory approval, but health insurers and other payers typically refuse to support access to them. Thus, patients are left to bear significant out-of-pocket costs for obesity pharmacotherapy. This study aimed to assess preferences and willingness to pay (WTP) for obesity medications among people seeking weight loss in the United States and United Kingdom. An online survey was developed based on literature review, clinician interviews, and profiles of available therapies. Participants indicated their preference for hypothetical treatments which varied by seven attributes: percentage of weight loss, long-term health risk reduction, time to noticeable weight loss, delivery mode, side effects, lifestyle modification, and cost; 502 obese participants completed the survey (mean BMI 37.12 kg/m(2) (±4.63); 73.5% female; 47.7 (±12.9) years of age). The participants deemed weight loss of >21 kg (United Kingdom) and >28 kg (United State) as "acceptable". All treatment attributes were important (P < 0.001) except "time to noticeable weight loss." The survey found that percentage weight loss was the most important factor for patients and a reduction in long-term health risk was relatively less important. Patients were willing to pay £6.51/$10.49 per month per percentage point of weight loss that a pharmacotherapy could provide. Participants also highly valued therapies that did not require substantial lifestyle modifications and were willing to pay £17.78/$30.77 more per month for a one-pill-per-day treatment vs. a weekly injectable. Participants placed a high value on weight loss and avoiding changes to their lifestyle, and less value on reducing long-term risks to health.  相似文献

In natural protected areas, ecotourism could provide the impetus andeconomic investment for improved conservation of species and habitats. However,few studies have attempted to characterise sustainable ecotourism and positiveexamples of ecotourism are still rare. This study conducted a series ofinterviews at the local, regional, and national level in order to identifygeneral feeling and concerns of government and non-government institutions withrespect to ecotourism. Questionnaires were used to assess the extent offulfillment of ecotourism principles by tour operators in protected areas of LaPaz Bay. Government and non-government institutions interviewed expectedecotourism to be a means for regional development, a conservation strategy andcompatible with conservation activities. Ecotourism operators surveyed were morelikely to be considered ecotourism ventures, reaching on average 10 indicators( 3, n = 14), and were found to be providing, insome way, benefits to the conservation of the area. Current ecotourismactivities may provide benefits for conservation, but are not comparable to thecosts involved in the conservation of the protected areas concerned. Hence,current ecotourism activities have not met the expectations of the protectedarea managers. The role that ecotourism can play as a conservation strategydepends on the strategies designed by protected area managers to take touroperators to share the costs and benefits of environmental services.  相似文献

Over the past fifty years, the world's wildlife populations have drastically declined. This stems from multiple causes, including the loss of natural habitat, which plays a vital role. Effective strategies to help endangered wildlife species recovery requires broad public support to be politically viable. In this study, we conducted a randomized survey to elicit and describe the Quebec population’s preferences and concerns regarding endangered wildlife and estimate its willingness-to-pay (WTP) for their recovery. We used stated preference approaches, namely a discrete choice experiment (DCE) and best-worst scaling (BWS), to estimate WTP and rank respondent preferences towards categories of wildlife species and recovery program attributes. In the selection of animals listed, results also reveal strong public preferences for large mammals, more specifically the beluga whale and woodland caribou. Simulation exercises from our DCE results show that a quarter of respondents would be willing to pay $160 per year for a megafauna recovery program compared to $12 for birds, or insects, or fish and molluscs recovery programs. Despite respondents’ strong preferences for the protection of megafauna, BWS and DCE simulation results indicate that a broader multispecies approach would be favoured by a larger segment of the population than a single specie approach. The survey results also revealed that the public likes to spend time in nature and is both concerned about endangered wildlife and aware of the interdependence between humans and nature. Therefore, our findings suggest that policymakers have a social acceptance to use both flagship species and multispecies approaches to implement endangered species recovery strategies. Moreover, our findings and the related literature on the value of ecosystem services indicate that communication on wildlife conservation could be buttressed by emphasizing conservation’s contributions to ecosystem services.  相似文献

In this article we present an international Indigenous people’s partnership project co-led by two Indigenous communities, Musqueam (Coast Salish, Canada) and Totoras (Quichua, Ecuador), as a community-driven health initiative. The Musqueam-Totoras partnership includes Indigenous organizations, universities, international agencies, government, and nongovernmental organizations to address Indigenous health concerns in both communities. Our collaborative approach provides a framework to (a) increase the development expertise of Indigenous people internationally, (b) increase skills among all participants, and (c) facilitate Indigenous knowledge mobilization and translation to promote cultural continuity. This international Indigenous people’s partnership between north and south reflects the diversity and commonalities of Indigenous knowledge, contributes to cultural revitalization, and minimizes the impact of assimilation, technology, and globalization. Indigenous people’s partnerships contribute to self-determination, which is a prerequisite to the building and maintenance of healthy communities and the promotion of social justice. The exchange of Indigenous knowledge upholds Indigenous values of respect, reciprocity, relevance, and responsibility. Given the history of colonization and the negligence of governments in the exercising of these values with respect to Indigenous communities, this contemporary exchange among Indigenous people in the Americas serves to reclaim these values and practices. International cooperation empowering Indigenous people and other marginalized groups has become fundamental for their advancement and participation in globalized economies. An international Indigenous people’s partnership provides opportunities for sharing cultural, historical, social, environmental, and economic factors impacting Indigenous health. These partnerships also create beneficial learning experiences in community-based participatory research and community-driven health initiatives, provide culturally sensitive research ethics frameworks, increase capacity building, and address basic human needs identified by participating communities.  相似文献

Recent evidence strongly suggests that biodiversity loss and ecosystem degradation continue. How might a systems approach to ecology help us better understand and address these issues? Systems approaches play a very limited role in the science that underpins traditional biodiversity conservation, but could provide important insights into mechanisms that affect population growth. This potential is illustrated using data from a critically endangered bird population. Although species-specific insights have practical value, the main applied challenge for a systems approach is to help improve our understanding of the role of biodiversity in the context of ecosystem services (ES) and the associated values and benefits people derive from these services. This has profound implications for the way we conceptualize and address ecological problems. Instead of focusing directly on biodiversity, the important response variables become measures of values and benefits, ES or ecosystem processes. We then need to understand the sensitivity of these variables to biodiversity change relative to other abiotic or anthropogenic factors, which includes exploring the role of variability at different levels of biological organization. These issues are discussed using the recent UK National Ecosystems Assessment as a framework.  相似文献

Public preferences for ecological restoration can be revealed through environmental valuation studies that aim to measure willingness to pay. However, respondents' environmental views will often influence the conclusions drawn from such studies. We conducted a national survey of perceptions of the benefits and perverse outcomes arising from ecological restoration using a dichotomous choice payment card. Using interval regression to estimate willingness to pay, we find that there are respondents who will perceive mostly biodiversity benefits from restoration, with a particular interest in threatened species recovery. We find that this eco‐centric view of the benefits of restoration also increases the dollar amount that respondents are willing to pay to support restoration activities. A proportion of respondents also perceive restoration as having negative impacts, with concerns orientated towards increased fire, decreased farmland productivity, and groundwater availability. Perceptions of the potential effects of restoration on land productivity had a significant negative influence on the amount of money respondents were willing to pay. These findings are useful for targeting outreach in order to garner public support for ecological restoration.  相似文献

There is increasing evidence that global climate change will alter the spatiotemporal occurrences and abundances of many species at continental scales. This will have implications for efficient conservation of biodiversity. We investigate if the general public in Denmark are willing to pay for the preservation of birds potentially immigrating and establishing breeding populations due to climate change to the same extent that they are for native species populations currently breeding in Denmark, but potentially emigrating due to climate change. We find that Danish citizens are willing to pay much more for the conservation of birds currently native to Denmark, than for bird species moving into the country – even when they are informed about the potential range shifts associated with climate change. The only exception is when immigrating species populations are under pressure at European level. Furthermore, people believing climate change to be man-made and people more knowledgeable about birds tended to have higher WTP for conservation of native species, relative to other people, whereas their preferences for conserving immigrant species generally resembled those of other people. Conservation investments rely heavily on public funding and hence on public support. Our results suggest that cross-country coordination of conservation efforts under climate change will be challenging in terms of achieving an appropriate balance between cost-effectiveness in adaptation and the concerns of a general public who seem mostly worried about protecting currently-native species.  相似文献

Several recent surveys have asked Americans whether they support policies to reduce childhood obesity. There is reason for skepticism of such surveys because people are not confronted with the tax costs of such policies when they are asked whether they support them. This paper uses contingent valuation (CV), a method frequently used to estimate people's willingness to pay (WTP) for goods or services not transacted in markets, applied to unique survey data from New York State to estimate the willingness to pay to reduce childhood obesity. The willingness to pay data correlate in predictable ways with respondent characteristics. The mean WTP for a 50% reduction in childhood obesity is $46.41 (95% CI: $33.45, $59.15), which implies a total WTP by New York State residents of $690.6 million (95% CI: $497.7, $880.15), which is less than that implied by previous surveys that did not use CV methods but greater than current spending on policies to reduce childhood obesity and greater than the estimated savings in external costs. The findings provide policymakers with useful information about taxpayers' support for, and preferred budget for, anti-obesity policies.  相似文献

This study explored the health, well-being, and social capital benefits gained by community members who are involved in the management of land for conservation in six rural communities across Victoria. A total of 102 people participated in the study (64 males; 38 females) comprising 51 members of a community-based land management group and 51 controls matched by age and gender. Mixed methods were employed, including the use of an adapted version of Buckner’s (1988) Community Cohesion Scale. The results indicate that involvement in the management of land for conservation may contribute to both the health and well-being of members, and to the social capital of the local community. The members of the land management groups rated their general health higher, reported visiting the doctor less often, felt safer in the local community, and utilized the skills that they have acquired in their lifetime more frequently than the control participants. Male members reported the highest level of general health, and the greatest satisfaction with daily activities. Members also reported a greater sense of belonging to the local community and a greater willingness to work toward improving their community than their control counterparts. Of equal importance is evidence that involvement in voluntary conservation work constitutes a means of building social capital in rural communities which may help reduce some of the negative aspects of rural life.  相似文献

Community-based ecotourism (CBET) has become a popular tool for biodiversity conservation, based on the principle that biodiversity must pay for itself by generating economic benefits, particularly for local people. There are many examples of projects that produce revenues for local communities and improve local attitudes towards conservation, but the contribution of CBET to conservation and local economic development is limited by factors such as the small areas and few people involved, limited earnings, weak linkages between biodiversity gains and commercial success, and the competitive and specialized nature of the tourism industry. Many CBET projects cited as success stories actually involve little change in existing local land and resource-use practices, provide only a modest supplement to local livelihoods, and remain dependent on external support for long periods, if not indefinitely. Investment in CBET might be justified in cases where such small changes and benefits can yield significant conservation and social benefits, although it must still be recognized as requiring a long term funding commitment. Here, I aim to identify conditions under which CBET is, and is not, likely to be effective, efficient and sustainable compared with alternative approaches for conserving biodiversity. I also highlight the need for better data and more rigorous analysis of both conservation and economic impacts.  相似文献

北京香山公园自然景观价值二十年变迁   总被引:1,自引:0,他引:1  
成程  肖燚  饶恩明 《生态学报》2014,34(20):6020-6027
自然景观是由自然环境、物质和景象构成,具有观赏、游览、休闲、疗养等效用和价值的风景综合体或景物。然而,人们在开发利用自然资源时,并没有将自然景观的价值纳入到费用效益分析中,这种对自然景观价值的忽略和低估导致了各种不可逆转的环境问题。如果赋予自然景观合适的经济价值并探究其价值变化,能为其开发利用提供决策支持。以北京香山公园为例,构建了价值评估的指标体系:即自然景观价值为使用价值与非使用价值之和。并对这两种价值分别运用个体旅行费用法和条件价值法进行评估,得出2012年香山公园的使用价值为19.25亿元,非使用价值为3.46亿元。对香山公园在1992—2012年20年间的自然景观价值变化进行深入的研究发现,其景观价值由1992年的0.175亿元增长到2012年的22.71亿元,增长近130倍,速率为1.13亿元/a,游客量的加倍增长、人们游览支出的提高,以及支付意愿的增长是产生该变化的主要原因。随着环境污染和生态破坏的日益加剧以及人们对健康生活的迫切向往,香山公园自然景观价值仍将持续增长,景区当局应全面认识香山公园所承载的价值,在发展旅游的同时也要积极探索解决现有生态环境问题的新思路。  相似文献

In 1991, the Australian Commonwealth Parliament unanimously passed the Council for Aboriginal Reconciliation Act 1991. This Act implemented a 10-year process that aimed to reconcile Indigenous and non-Indigenous people by the end of 2000. One of the highest priorities of the reconciliation process was to address Indigenous socio-economic disadvantage, including health, education and housing. However, despite this prioritising, both the Keating Government (1991–1996) and the Howard Government (1996–2000) failed to substantially improve socio-economic outcomes for Indigenous people over the reconciliation decade. In this paper, I examine one of the most prominent socio-economic areas, that of Indigenous health. First, I discuss the appalling levels of Indigenous health throughout the reconciliation decade by analysing a number of health indicators, including life expectancy, infant mortality rate, standard mortality ratios, hospital rates and health Infrastructure. This analysis reveals significant and often worsening disadvantage in these health indicators. Second, I analyse a number of policies and programs concerning Indigenous socio-economic disadvantage that were developed by Commonwealth Governments in the 1990s. I argue that these policies and programs largely failed to address Indigenous socio-economic disadvantage. I also discuss alternative policies and programs that could reduce the significant levels of socio-economic disadvantage suffered by Indigenous people.  相似文献
