Multicriteria decision support systems are applied in natural resource management in order to clarify the planning process for the stakeholders, to make all available information usable and all objectives manageable. Especially when the public is involved in planning, the decision support system should be easy to comprehend, transparent and fair. Social choice theory has recently been applied to group decision-making in natural resources management to accomplish these objectives. Although voting forms the basis of democracy, and is usually taken as a fair method, the influence of voters over the outcome may vary. It is also possible to vote strategically to improve the results from each stakeholder's point of view. This study examines the use of social choice theory in revealing stakeholders' preferences in participatory forest planning, and the influence of different voters on the outcome. The positional voting rules examined were approval voting and Borda count, but both rules were slightly modified for the purposes of this study. The third rule examined, cumulative rule, resembles utilitarian voting rules. The voting rules were tested in a real participatory forest planning situation in eastern Lapland, Finland. All voting rules resulted in a different joint order of importance of the criteria. Yet, the preference orders produced had also a lot in common and the criteria could be divided into three quite distinct groups according to their importance. The influence of individual voters varied between the voting rules, and in each case different voter was the most influential. 相似文献

It has been argued that strategies to manage natural areas important for tourism and recreation should integrate an understanding
of tourist preferences for specific natural features. However, the accuracy of tourist recalled perceptions of environmental
attributes, which are usually derived from post hoc surveys and used to establish management priorities, is currently unmeasured.
We tested the validity of the relationship between tourist-stated preferences and actual condition of coral reefs around the
Caribbean island of Bonaire. Using standardized questionnaires, we asked 200 divers to select their most and least favorite
dive sites and the attributes that contributed to that selection. We also carried out ecological surveys at 76 of the 81 dives
sites around the island to assess the actual conditions of the attributes indicated as important for site selection. Fish-
and coral-related attributes were key features affecting dive enjoyment. In general, divers appeared to be able to perceive
differences between sites in the true condition of biological attributes such as fish species richness, total number of fish
schools, live coral cover, coral species richness, and reef structural complexity, although men and women divers differed
in their ability to perceive/recall some of the attributes. Perceived differences in environmental attributes, such as surface
conditions, underwater current, and the likelihood of encountering rare fish and sea turtles, were not empirically validated.
The fact that divers perceive correctly differences in the condition of some of the key biological attributes that affect
dive enjoyment reinforces the need to maintain overall reef condition at satisfactory levels. However, variation in accuracy
of perceptions owing to demographic factors and attribute type suggests the need for caution when using public perceptions
to develop environmental management strategies, particularly for coral reefs. 相似文献

Perceptions, preferences, and reactions of local inhabitants in Vikos-Aoos National Park, Greece 总被引:1,自引:0,他引:1
Trakolis D 《Environmental management》2001,28(5):665-676
Local inhabitants' perceptions, preferences, and reactions were investigated in Vikos-Aoos National Park, 25 years after its
designation. Knowledge of aims of the park and source of information about them, necessity for infrastructure, reactions to
certain policies, and effectiveness of administration and management scheme were studied by means of a questionnaire survey.
Personal interviews were performed by systematic sampling, which resulted in 203 cases for analysis. Most respondents said
that they had knowledge of the aims of the national park, and this was positively associated with education; protection of
flora and fauna was identified by most as the main aim, and the management authority (the Forest Service) ranked first in
order as source of information. Tourism development of the area was seen as a positive change, and recreation facilities and
improvement in accessibility were considered of high priority for development. The investigation into peoples' reactions to
several possible alternative management policies revealed willingness to accept certain restrictions on their agricultural
use of the land. A policy of nonintensive agriculture with compensation for loss of income, if the ecosystems of the park
were in danger, seems the most acceptable. Long-term leasing of farms by the Forest Service was another policy with a high
degree of acceptance, especially for certain occupational groups; those working in the secondary and tertiary sectors of economy
would accept such a policy more easily than those working in the primary sector. Finally, a very large majority of the respondents
expressed a preference for a new administration and management scheme with the participation of local communities in the decision-making
process. 相似文献

Blue space: The importance of water for preference,affect, and restorativeness ratings of natural and built scenes 总被引:2,自引:0,他引:2

Although theorists have suggested that aquatic environments or “blue space” might have particular restorative potential, to date there is little systematic empirical research on this issue. Indeed the presence of water has, unintentionally, been a confounding factor in research comparing people’s reactions to built and natural environments. Whereas aquatic features (rivers, lakes, coasts) are frequently present in visual stimuli representing natural environments they are rarely incorporated in stimuli portraying built environments. As many towns are, for good reason, located near water this is a potentially significant oversight. The current research collated a set of 120 photographs of natural and built scenes, half of which contained “aquatic” elements. Proportions of “aquatic”/“green”/“built” environments in each scene (e.g. 1/3rd, 2/3rds) were also standardised. Two studies investigated preferences (attractiveness, willingness to visit and willingness to pay for a hotel room with the view), affect and perceived restorativeness ratings for these photographs. As predicted, both natural and built scenes containing water were associated with higher preferences, greater positive affect and higher perceived restorativeness than those without water. Effect sizes were consistently large. Intriguingly, images of “built” environments containing water were generally rated just as positively as natural “green” space. We propose a number of avenues for further research including exploration of the mechanisms underlying these effects. 相似文献

The current industrial pig production model is in crisis, due to its association with environmental pollution, doubtful product quality and lack of animal well-being. In Bretagne (France), a region of intensive pig production, a survey of seven stakeholder groups concerned with pig production was conducted, as part of a research programme dedicated to the assessment of the environmental impact of different modes of pig production. A very large majority of pig producers (93%) and their suppliers (100%) considers pig farms as an asset for the region, whereas a majority of scientists (58%), activists (78%) and consumers (54%) sees it as a handicap. Differences among stakeholder groups are minor with respect to the perceived importance of environmental and social issues. Stakeholders agree on the relative level of responsibility of pig farms with respect to specific problems. For all groups unpleasant odours and water quality come first with respect to responsibility, for most groups soil quality comes second, followed by product safety and air quality. For a future improved mode of pig production, 76% of pig producers and their suppliers prefer to adapt the current model, for all other groups the majority prefers an alternative model. While pig producers and their suppliers prefer a slurry-based housing system, all other groups prefer a straw-based system. Pig producers see the slurry-based system as technically superior and associate the straw-based system with poor working conditions, whereas consumers associate the slurry-based system in the first place with poor water quality and associate the straw-based system with less pollution. These results will be of use in the research programme on the environmental impact of modes of pig production, as they indicate the environmental impacts to be considered and their relative importance. The results will also help in deciding which options should be assessed. It is concluded that the poor image of the current pig production model and its production practices with consumers does not seem compatible with a sustainable demand for pork products. 相似文献
