Planning and management for recreational activities in protected areas involves an understanding of many complex factors.
Segmentation of recreation demand and of the main physical or sporting activities can contribute to the design of more efficient
management strategies, which may help to maintain or significantly enhance satisfaction with the recreation experience, and
this in turn could improve the interest in and appreciation of the natural environment. The current study examined the motivations
of hikers in three small Natura 2000 protected areas. It establishes a typology or categorization as a contribution to better
management based on a survey conducted through on-site personal interviews with a representative sample of 569 hikers. Through
an analysis of the principal intervening components by means of cluster analysis, we identified three groups of hikers based
on three motivational dimensions: (1) nature-minded hikers, (2) sporting hikers and (3) general-purpose hikers. The most striking
results were the significant differences among group variables related to visit behaviour (frequency and duration of visits
and number of people per group), previous knowledge (protection status of the areas) and recreational frequentation (trail
categories and protected areas visited). A positive correlation between the degree of sympathy for nature and the degree of
satisfaction with the recreational experience (including positive evaluation of the public facilities, signposting and services
offered) was also observed. The results are discussed in terms of their applicability and implications in hiking management
in protected natural areas such as those of Natura 2000. 相似文献

The implementation of adaptation actions in local conservation management is a new and complex task with multiple facets, influenced by factors differing from site to site. A transdisciplinary perspective is therefore required to identify and implement effective solutions. To address this, the International Conference on Managing Protected Areas under Climate Change brought together international scientists, conservation managers, and decision-makers to discuss current experiences with local adaptation of conservation management. This paper summarizes the main issues for implementing adaptation that emerged from the conference. These include a series of conclusions and recommendations on monitoring, sensitivity assessment, current and future management practices, and legal and policy aspects. A range of spatial and temporal scales must be considered in the implementation of climate-adapted management. The adaptation process must be area-specific and consider the ecosystem and the social and economic conditions within and beyond protected area boundaries. However, a strategic overview is also needed: management at each site should be informed by conservation priorities and likely impacts of climate change at regional or even wider scales. Acting across these levels will be a long and continuous process, requiring coordination with actors outside the “traditional” conservation sector. To achieve this, a range of research, communication, and policy/legal actions is required. We identify a series of important actions that need to be taken at different scales to enable managers of protected sites to adapt successfully to a changing climate. 相似文献

Marine protected areas (MPAs) provide place-based management of marine ecosystems through various degrees and types of protective actions. Habitats such as coral reefs are especially susceptible to degradation resulting from climate change, as evidenced by mass bleaching events over the past two decades. Marine ecosystems are being altered by direct effects of climate change including ocean warming, ocean acidification, rising sea level, changing circulation patterns, increasing severity of storms, and changing freshwater influxes. As impacts of climate change strengthen they may exacerbate effects of existing stressors and require new or modified management approaches; MPA networks are generally accepted as an improvement over individual MPAs to address multiple threats to the marine environment. While MPA networks are considered a potentially effective management approach for conserving marine biodiversity, they should be established in conjunction with other management strategies, such as fisheries regulations and reductions of nutrients and other forms of land-based pollution. Information about interactions between climate change and more “traditional” stressors is limited. MPA managers are faced with high levels of uncertainty about likely outcomes of management actions because climate change impacts have strong interactions with existing stressors, such as land-based sources of pollution, overfishing and destructive fishing practices, invasive species, and diseases. Management options include ameliorating existing stressors, protecting potentially resilient areas, developing networks of MPAs, and integrating climate change into MPA planning, management, and evaluation. 相似文献

This paper discusses the complexity of the protected area mosaic that has evolved in the United Kingdom over the past 40 or so years. Experimental matrices have been used to assist in the analysis of the various types of protected areas. The trend has been towards the development of protected areas to serve multiple objectives, although categories of protected area introduced under European legislation are more narrowly defined. There has been a proliferation in the number of categories of protected area in the past ten years; since 1990 six new categories of protected area have been established, two resulting from European directives. Most of the protected areas operate indirectly through the planning system and/or voluntary agreements. However, a distinction is drawn between systems for nature conservation and landscape protection with the former relying more on direct controls (ownership and/or legal force). There is considerable potential overlap of protected areas. New categories of protected area have often been superimposed upon the existing system without consideration of whether they will result in duplication of effort, expenditure etc. We conclude that there is scope for some rationalization of the system. Ideally this would involve replacing existing protected areas with broader based ones but considerable simplification could be obtained in practice by making the powers of the agencies more flexible and changing the administrative arrangements for managing the various protected areas. 相似文献

Agriculture is being increasingly integrated into the UK's land use planning system and recently approved amendments to the EU's Environmental (Impact) Assessment Directive will further this integration and cause more assessments of more projects on a mandatory basis. This paper reviews recent research on the quality of assessments and argues that Environmental Statements of agricultural projects are of a much lower standard than those for other project types and that improvements will need to be made as a result of the changes to the Directive. 相似文献

Climate change will pose increasingly significant challenges to managers of parks and other forms of protected areas around
the world. Over the past two decades, numerous scientific publications have identified potential adaptations, but their suitability
from legal, policy, financial, internal capacity, and other management perspectives has not been evaluated for any protected
area agency or organization. In this study, a panel of protected area experts applied a Policy Delphi methodology to identify
and evaluate climate change adaptation options across the primary management areas of a protected area agency in Canada. The
panel identified and evaluated one hundred and sixty five (165) adaptation options for their perceived desirability and feasibility.
While the results revealed a high level of agreement with respect to the desirability of adaptation options and a moderate
level of capacity pertaining to policy formulation and management direction, a perception of low capacity for implementation
in most other program areas was identified. A separate panel of senior park agency decision-makers used a multiple criterion
decision-facilitation matrix to further evaluate the institutional feasibility of the 56 most desirable adaptation options
identified by the initial expert panel and to prioritize them for consideration in a climate change action plan. Critically,
only two of the 56 adaptation options evaluated by senior decision-makers were deemed definitely implementable, due largely
to fiscal and internal capacity limitations. These challenges are common to protected area agencies in developed countries
and pervade those in developing countries, revealing that limited adaptive capacity represents a substantive barrier to biodiversity
conservation and other protected area management objectives in an era of rapid climate change. 相似文献

The experience of Saudi Arabia in environmental policies is relatively recent. However, the Government has established policy direction and administrative bodies to carry out its policy proposals. This endeavour to construct a framework for environmental policies has been hindered by several obstacles. The paper assesses government efforts in this field by reviewing environmental policy documents, the environmental administrative structure and the environmental decision-making process. A background of environmental policies and legislation is given in addition to categories of environmental agencies. 相似文献

Geographic information systems and remote sensing technologies have become an important tool for visualizing conservation management and developing solutions to problems associated with conservation. When multiple organizations separately develop spatial data representations of protected areas, implicit error arises due to variation between data sets. We used boundary data produced by three conservation organizations (International Union for the Conservation of Nature, World Resource Institute, and Uganda Wildlife Authority), for seven Ugandan parks, to study variation in the size represented and the location of boundaries. We found variation in the extent of overlapping total area encompassed by the three data sources, ranging from miniscule (0.4 %) differences to quite large ones (9.0 %). To underscore how protected area boundary discrepancies may have implications to protected area management, we used a landcover classification, defining crop, shrub, forest, savanna, and grassland. The total area in the different landcover classes varied most in smaller protected areas (those less than 329 km2), with forest and cropland area estimates varying up to 65 %. The discrepancies introduced by boundary errors could, in this hypothetical case, generate erroneous findings and could have a significant impact on conservation, such as local-scale management for encroachment and larger-scale assessments of deforestation. 相似文献

The Fate of Priority Areas for Conservation in Protected Areas: A Fine-Scale Markov Chain Approach 总被引:1,自引:0,他引:1
Park managers in alpine areas must deal with the increase in forest coverage that has been observed in most European mountain
areas, where traditional farming and agricultural practices have been abandoned. The aim of this study is to develop a fine-scale
model of a broad area to support the managers of Paneveggio Nature Park (Italy) in conservation planning by focusing on the
fate of priority areas for conservation in the next 50–100 years. GIS analyses were performed to assess the afforestation
dynamic over time using two historical maps (from 1859 and 1936) and a series of aerial photographs and ortho-photos (taken
from 1954 to 2006) covering a time span of 150 years. The results show an increase in the forest surface area of about 35%.
Additionally, the forest became progressively more compact and less fragmented, with a consequent loss of ecotones and open
habitats that are important for biodiversity. Markov chain-cellular automata models were used to project future changes, evaluating
the effects on a habitat scale. Simulations show that some habitats defined as priority by the EU Habitat Directive will be
compromised by the forest expansion by 2050 and suffer a consistent loss by 2100. This protocol, applied to other areas, can
be used for designing long-term management measures with a focus on habitats where conservation status is at risk. 相似文献

The primary objective of planning in protected natural areas should be the conservation of their inherent natural values. With this idea in mind, a proposal of an objective method for the environmental planning of a protected natural area is presented. The method used was principal components analysis, a multivariate analysis technique that integrates the natural value and the state of conservation (the degree of alteration due to human activity) of the main characteristics of the environment. The method is applied to the specific case of a protected natural area in the Comunidad de Madrid (Madrid Autonomous Region), Spain. 相似文献

Despite the popularity of marine protected areas (MPAs) as a management tool, increasing evidence shows that many fail to
achieve conservation objectives. Although several MPAs exist in Sri Lanka, most are not managed, and resource extraction and
habitat degradation continue unabated. At present, the declaration and management of MPAs is carried out without adequate
consideration of the ecology, socioeconomic realities, or long-term management sustainability. Managers have focused more
toward the creation of new legislation and protected areas rather than ensuring the implementation of existing regulations
and management of existing protected areas. Poor coordination and a lack of serious political will have also hindered successful
resource management. As in other developing countries, MPA managers have to contend with coastal communities that are directly
dependant on marine resources for their subsistence. This often makes it unfeasible to exclude resource users, and MPAs have
failed to attract necessary government support because many politicians are partial toward the immediate needs of local communities
for both economic and political reasons. A more integrated approach, and decisions based on the analysis of all relevant criteria
combined with a concerted and genuine effort toward implementing strategies and achieving predetermined targets, is needed
for effective management of MPAs and the sustainable use of marine resources in Sri Lanka. 相似文献

Hypoxic blackwater events occur when large amounts of organic material are leached into a water body (e.g., during floodplain inundation) and rapid metabolism of this carbon depletes oxygen from the water column, often with catastrophic effects on the aquatic environment. River regulation may have increased the frequency and severity of hypoxic blackwater events in lowland river systems, necessitating management intervention to mitigate the impacts of these events on aquatic biota. We examine the effectiveness of a range of mitigation interventions that have been used during large-scale hypoxic blackwater events in the Murray–Darling Basin, Australia and that may be applicable in other environments at risk from hypoxic blackwater. Strategies for hypoxia mitigation include: delivery of dilution flows; enhancement of physical re-aeration rates by increasing surface turbulence; and diversion of blackwater into shallow off-channel storages. We show that the impact of dilution water delivery is determined by relative volumes and water quality and can be predicted using simple models. At the dilution water inflow point, localized oxygenated plumes may also act as refuges. Physical re-aeration strategies generally result in only a small increase in dissolved oxygen but may be beneficial for local refuge protection. Dilution and natural re-aeration processes in large, shallow lake systems can be sufficient to compensate for hypoxic inflows and water processed in off-channel lakes may be able to be returned to the river channel as dilution flows. We provide a set of predictive models (as electronic supplementary material) for estimation of the re-aeration potential of intervention activities and a framework to guide the adaptive management of future hypoxic blackwater events. 相似文献

International institutions, understood as sets of rules contained in international agreements, are aimed at orienting national
governments towards specific policy options. Nevertheless, they can determine a change in national policies and practices
only if states are willing and capable of incorporating international obligations into their national legislations and ensuring
their application and enforcement in areas that follow completely under national jurisdiction. The establishment of marine
protected areas promoted by international agreements as a tool for the protection of marine resources represents an interesting
case for revealing the complex interactions between international institutions and national actors. Particularly, the establishment
of these areas in Senegal shows the salience of domestic constellations of actors who may support or undercut national commitments
to international regimes: political elites, bureaucracies, the general public and target groups. By anchoring the empirical
analysis to an actor-centred institutionalist perspective, the article explains how dynamic constellations of actors can distort
the penetration of international objectives in the national policy framework. Different constellations of national actors
can indeed bend international institutions at different moments: during the formulation of a new law in line with international
obligations; in the definition of its implementation framework; and in the enforcement of national policies. 相似文献

Marine Protected Dramas: The Flaws of the Brazilian National System of Marine Protected Areas 总被引:1,自引:0,他引:1

This article discusses the current problems and issues associated with the implementation of a National System of Marine Protected
Areas in Brazil. MPA managers and higher governmental level authorities were interviewed about their perceptions of the implementation
of a national MPA strategy and the recent changes in the institutional arrangement of government marine conservation agencies.
Interviewees’ narratives were generally pessimistic and the National System was perceived as weak, with few recognizable marine
conservation outcomes on the ground. The following major flaws were identified: poor inter-institutional coordination of coastal
and ocean governance; institutional crisis faced by the national government marine conservation agency; poor management within
individual MPAs; problems with regional networks of marine protected areas; an overly bureaucratic management and administrative
system; financial shortages creating structural problems and a disconnect between MPA policy and its delivery. Furthermore,
a lack of professional motivation and a pessimistic atmosphere was encountered during many interviews, a malaise which we
believe affects how the entire system is able to respond to crises. Our findings highlight the need for a better understanding
of the role of ‘leadership’ in the performance of socio-ecological systems (such as MPA networks), more effective official
evaluation mechanisms, more localized audits of (and reforms if necessary to) Brazil’s federal biodiversity conservation agency
(ICMBio), and the need for political measures to promote state leadership and support. Continuing to focus on the designation
of more MPAs whilst not fully addressing these issues will achieve little beyond fulfilling, on paper, Brazil’s international
marine biodiversity commitments. 相似文献

The number of MPAs has increased sharply, from just 118 in 1970 to well over 6,300 today. This growth in numbers has also been accompanied by a voluminous growth in the academic literature on the theme, with writers employing ecologic, economic and governance lenses (or a combination thereof) to both support the case for MPA creation, and to evaluate just how successfully (or not) existing MPAs match up to their promises. Research suggests effective management of such protected areas is vital if desired outcomes are to be achieved within the allotted time period. This Special Feature on MPAs therefore seeks to address two key questions derived from the management effectiveness framework of Hockings and others (2000), namely: ‘How appropriate are the management systems and processes in place?’ and ‘Were the desired Objectives achieved—and if so, why?’ Fourteen articles, drawing on different disciplinary perspectives relating to MPA experiences from across the globe, offers insights into these questions by considering, inter alia, how: are MPA sites selected?; is ‘buy-in’ to the process from the various stakeholders achieved?; are these stakeholder’s views reflected in the management systems that evolve?, and what monitoring and evaluation mechanisms are in place? Bringing these perspectives and approaches together through the medium of this Special Feature is thus intended to further our understanding of the different issues that may confront both planners and managers of Marine Protected Areas. 相似文献

The lack of scientific baseline information hinders appropriate design and management of protected areas. To illustrate the value of science to management, we consider five scenarios for the 202.0 km² Puerto Princesa Subterranean River National Park, Philippines: (1) closure to human activities, (2) and (3) two levels of increase in unplanned human activities, (4) creation of a forest corridor and (5) additional allocation of land for permanent or shifting agriculture. We then use habitat-specific bird density estimates to simulate the net effect of each scenario on 18 focal bird populations. Closure has significant benefits—populations of five species are predicted to increase by >50 % and nine by >25 %, but two secondary forest flycatchers, including the endemic and ‘Vulnerable’ Palawan flycatcher, decline dramatically, while the creation of a 4.0 km² forest corridor yields average increases across species of 2 ± 4 % (SD). In contrast, heavier unplanned park usage produces declines in all but a few species, while the negative effects of an extra 2.0 km² of shifting cultivation are 3–5 times higher than for a similar area of permanent agriculture and affect species whose densities are highest in primary habitats. Relatively small changes within the park, especially those associated with agricultural expansion, has serious predicted implications for local bird populations. Our models do not take into account the full complexities of bird ecology at a site, but they do provide park managers with an evidence base from which to make better decisions relating to biodiversity conservation obligations which their parks are intended to meet. 相似文献

/ An approach to evaluating the effectiveness of management of protected areas is proposed. This approach has been used in developing an evaluation strategy for the Fraser Island World Heritage Area in Australia. The main component of the strategy is built upon the desired outcomes specified in the management plan for the area and thus provides a basis for assessing the extent to which the plan's objectives are being achieved. A series of monitoring programs have been proposed to enable this assessment. Examples of monitoring programs developed as part of the evaluation strategy are presented. A second component of the strategy monitors the implementation of the management plan. A management information system has been developed to record and report on the extent to which the specific actions specified in the management plan have been implemented. The strategy is discussed in relation to seven objectives set for the evaluation program in its design phase.KEY WORDS: Planning; Evaluation; Monitoring; Management; Protected areas 相似文献

Partnerships between natural-area managers and the tourism industry have been suggested to contribute to sustainability in
protected areas. This article explores how important sustainability outcomes of partnerships are to their members, how well
they are realised and the features of partnerships leading to their achievement. In 21 case studies in Australia, interviews
(n = 97) and surveys (n = 100) showed that of 14 sustainability outcomes, improved understanding of protected areas values and improved biodiversity
conservation were the most important. Other highly ranked outcomes were greater respect for culture, heritage, and/or traditions;
improved quality of environmental conditions; social benefits to local communities; and improved economic viability of the
protected area. Scores for satisfaction with outcomes were, like those for importance, all high but were less than those for
importance for the majority, with improvement in quality of environmental conditions showing the largest gap. The satisfaction
score exceeded that for importance only for increased competitiveness of the protected area as a tourist destination. “Brown”
aspects of sustainability, i.e., decreased waste or energy use, were among the lowest-scoring outcomes for both importance
and satisfaction. The most important factor enabling sustainability outcomes was provision of benefits to partnership members.
Others were increased financial support, inclusiveness, supportive organisational and administrative arrangements, direct
involvement of decision makers, partnership maturity, creation of new relationships, decreased conflict, and stimulation of
innovation. Improving sustainability outcomes, therefore, requires maintaining these partnership attributes and also increasing
emphasis on reducing waste and resource use. 相似文献
