Knowledge and Willingness to Pay for the Conservation of Wildlife Species: Experimental Results Evaluating Australian Tropical Species
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo.
The nature of an experiment involving 204 residents is outlined and the results are reported and analysed. Two consecutive surveys of the respondents provide data about their stated knowledge of 23 wildlife species present in tropical Australia, most of which exclusively occur there. In addition, these surveys provide data about the willingness of respondents to pay for the conservation of those species belonging to three taxa; reptiles, mammals, and birds. Thus it is possible to compare the respondents’ stated knowledge of the species with their willingness to pay for their conservation, and to draw relevant inferences from this. From the initial survey and these associations, interesting relationships can be observed between those variables (knowledge...

Why farmers continue to use pesticides despite environmental health and sustainability costs
Provedor de dados: 31
Autores: Wilson,   Clevo; Tisdell,   Clement A.
Use of chemical inputs such as pesticides have increased agricultural production and productivity.  However, negative externalities, too, have increased.  The externalities include damage to the environment, agricultural land, fisheries, fauna and flora.  Another major externality has been the unintentional destruction of beneficial predators of insects which has led to a virulence of many species of agricultural pests.  Mortality and morbidity among agricultural workers, especially in developing countries from exposure to pesticides, are also common.  The costs from these externalities are large and affect farmers’ returns.  However, despite these high costs, farmers continue to use pesticides and in increasing quantities.  In this paper, we examine this...

Open-Cycle Hatcheries, Tourism and Conservation of Sea Turtles: Economic and Ecological Analysis
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo.
Considers the role that tourism-based sea turtle-hatcheries can play in conserving populations of sea turtles by combining economic analysis of markets with ecological parameters. Background is provided on the nature and development of such hatcheries in developing countries, giving particular attention to Sri Lanka. The modelling provided helps with the assessment of the impacts of turtle hatcheries on the conservation of sea turtles and enables ecological consequences of tourism, based on such hatcheries, to be better appreciated than in the absence of such modelling. The results demonstrate that sea turtle hatcheries that operate for tourist purposes can make a positive contribution to sea turtle conservation, but this depends on the manner in which...

Dynamic Processes in Contingent Valuation: A Case Study Involving the Mahogany Glider
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo; Swarna Nantha,   Hemanath.
This paper reports the results of an experiment involving a sample of 204 members of the public who were assessed on three occasions about their willingness to pay for the conservation of the mahogany glider. They were asked this question prior to information being provided to them about the glider and other focal wildlife species; after such information was provided, and finally after participants had had an opportunity to see live specimens of this glider. The mean willingness to pay of the relevant samples are compared and found to show significant variations. Theories are considered that help explain the dynamics of these variations. Serious concerns are raised about the capacity of information provision to reveal ‘true’ contingent valuations of public...

Knowledge of Birds and Willingness to Pay for their Conservation: An Australian Case Study
Provedor de dados: 31
Autores: Wilson,   Clevo; Tisdell,   Clement A.
This case study concentrates on the extent of knowledge of members of the Australian public of Australia’s tropical bird species and their willingness to pay for their conservation.  In order to place this issue in context, it first provides background information on the status of Australian bird species, focusing attention on species that occur in tropical Australia.  Then, using survey results, this study considers the hypothesis that the public’s relative support for the conservation of different bird species depends on its comparative knowledge of their existence and status.  Based on experimental results from a sample of residents of Brisbane, Queensland (Australia), it is found that their knowledge of bird species that occur exclusively in the...

Conservation and Economic Benefits of Wildlife-based Marine Tourism: Sea Turtles and Whales as Case Studies
Provedor de dados: 31
Autores: Wilson,   Clevo; Tisdell,   Clement A.
Tourism development can have positive and/or negative impacts on wildlife. However, if tourism is developed in accordance with the basic tenets of wildlife tourism such an activity can be sustainable and can aid the conservation of species.  Based on two case studies in Queensland, Australia, this article outlines the various economic and conservation benefits arising from wildlife-based tourism. Some of the benefits are direct, such as tangible economic benefits, others are less tangible, such as increased visitors’ willingness to pay in principle for the conservation of species. Wildlife-based tourism is shown to foster political support for the conservation of species utilized for such tourism by various mechanisms. Non-consumptive uses of wildlife are...

A Study of the Impact of Ecotourism on Environmental Education and Conservation: The case of Turtle Watching at an Australian Site
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo.
The importance of environmental education as a component of ecotourism is highlighted.  The extent of environmental education and its impact on attitudes to conservation of sea turtles and actions by ecotourists to support such conservation as a result of their visits to Mon Repos Conservation Park (Queensland), an important marine turtle rookery, is examined.  To do this, results from 519 usable survey forms completed by ecotourists are analysed.  It is found that a considerable amount of environmental education is obtained by visitors and that this has positive and statistically significant impacts on their desire to protect sea turtles and their intended actions to do so.  The importance of the interaction of tourists with wildlife as a contributor to...

OLS and Tobit Estimates: When is Substitution Defensible Operationally?
Provedor de dados: 31
Autores: Wilson,   Clevo; Tisdell,   Clement A.
Field data are used to illustrate that, other things constant, regression results using Ordinary Least Squares (OLS) converge to Tobit estimates as the number of zeros in the regressand decrease. Tobit estimates are theoretically superior to OLS estimates when using censored data. However, if little difference exists between OLS and Tobit estimates, OLS may be operationally acceptable. OLS may even be optimal in a bounded rationality sense because the extra cost of using Tobit analysis may be less than the extra benefits from a very slight increase in accuracy.

Empirical Evidence Showing The Relationships Between Three Approaches For Pollution Control
Provedor de dados: 31
Autores: Wilson,   Clevo.
Willingness to pay models have shown the theoretical relationships between the contingent valuation, cost of illness and the avertive behaviour approaches.  In this paper, field survey data are used to compare the relationships between these three approaches and to demonstrate that contingent valuation bids exceed the sum of cost of illness and the avertive behaviour approach estimates. The estimates provide a validity check for CV bids and further support the claim that contingent valuation studies are theoretically consistent.

Endangerment and Likeability of Wildlife Species: How Important are they for Proposed Payments for Conservation
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Swarna Nantha,   Hemanath; Wilson,   Clevo.
Examines empirically the relative influence of the degree of endangerment of wildlife species and their stated likeability on individuals’ willingness to pay (WTP) for their conservation. To do this, it utilises data obtained from the IUCN Red List and likeability and WTP data obtained from two serial surveys of a sample of the Australian public who were requested to assess 24 Australian wildlife species in each of three animal classes: mammals, birds and reptiles. Between the first and second survey, respondents were provided with extra information about the focal species. This information resulted in the clear dominance of endangerment as the major influence on the WTP of respondents for the conservation of the focal wildlife species. Our results throw...

Attitudes to entry fees to national parks: results and policy implications from a Queensland case study
Provedor de dados: 31
Autores: Wilson,   Clevo; Tisdell,   Clement A.
Examines visitor attitudes and whether visitors are willing to pay to enter Lamington National Park and under what circumstances they would do so. First a sample of visitors is asked a general (normative) question as to whether visitors should pay to visit Lamington National Park and in another question (positive) they are asked whether they would be more willing to pay if the money collected would be invested in the park to improve visitor facilities and for conservation work.  The results show that visitors are more willing to accept the ‘user-pays’ principle if the money will be used for the benefit of the national park and its visitors. It was found that foreigners are more in support for a ‘user-pay’ fee than Australians, and among Australians, those...

A Report on the Management of Saltwater Crocodiles (Crocodylus porosus) in the Northern Territory: Results of a Survey of Pastoralists
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo; Swarna Nantha,   Hemanath.
The management of saltwater crocodiles (Crocodylus porosus) in the Northern Territory is an important component of the State’s wildlife management policy. It encompasses saltwater crocodile control (the removal of problem crocodiles dangerous to humans and livestock), and the regulation of harvesting, farming and ranching of saltwater crocodiles for the production of commercial products. The distribution of saltwater crocodiles and their habitats often extend onto private and communal lands along the coastal belt of the Northern Territory,  and therefore are a concern of landholders both Aboriginal and pastoral. This report presents the findings of a study of managers of Northern Territory cattle properties (pastoralists). Their attitudes are surveyed...

Developing Ecotourism for the Survival of Sea Turtles
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo.
Discusses generally why humans should bother to conserve sea turtles. In doing so, it considers both economic and non-economic reasons and outlines threats to the existence of sea turtles and ways in which tourism may either contribute to the conservation or decline of their populations. Turtle-based ecotourism at Mon Repos in southern Queensland is described. As a result of a survey conducted by the authors, it is shown that turtle-based ecotourism at Mon Repos has positive social (indirect) consequences for the conservation of sea turtles. Furthermore, it is argued that ecotourism operations at Mon Repos have positive direct impacts on the sustainability of populations of sea turtles. However, using a simple model, it is demonstrated that this impact is...

Public Support for Sustainable Commercial Harvesting of Wildlife: An Australian Case Study
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo; Swarna Nantha,   Hemanath.
This paper surveys a sample of 204 members of the Australian public to determine their attitude to the sustainable commercial harvesting of wildlife generally, and considers their specific support for the sustainable commercial harvesting of each of 24 Australian native species. The general attitude of the sample to wildlife harvesting is related to their attitude to nature conservation. The relationship between respondents’ support for the sustainable commercial harvesting of each of the species and their degree of endangerment based on IUCN Red List rankings is established and found to be an inverse one. Support for the commercial sustainable use of each of the species is compared with the willingness of respondents to pay for their conservation. Support...

Dependence of public support for survival of wildlife species on their likeability
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo; Swarna Nantha,   Hemanath.
We surveyed a sample of 204 individuals selected from the public in Brisbane, Australia, to ascertain the extent to which they like or dislike 24 species of wildlife present in tropical Australia. The species belong to three classes: mammals, birds and reptiles. We calculated likeability indices for each of these species. We also asked respondents if they favoured the survival of each of these species and so the  percentage of respondents favouring survival of each of these species could be calculated. Thus, using linear regression analysis, the percentage of respondents favouring survival of each of the species was related to their indices of likeability. In addition, the data enables the average likeability of species in the three classes (mammals, birds...

How Knowledge Affects Payment to Conserve an Endangered Bird
Provedor de dados: 31
Autores: Wilson,   Clevo; Tisdell,   Clement A.
The paper reports the findings of an experimental survey conducted to determine the public’s willingness to pay for the protection and conservation of the golden-shouldered parrot in Australia. This parrot is endemic to Australia and is one of Australia’s most endangered birds. The paper examines the public’s knowledge of this parrot and compares it with other endangered birds as well as common birds and the public’s willingness to pay for conservation from a hypothetical allocation of money based on their current knowledge. We then examine how this allocation changes with increased knowledge about all species. Comparisons are made.

Wildlife-based Tourism and Increased Tourist Support for Nature Conservation Financially and Otherwise: Evidence from Sea Turtle Ecotourism at Mon Repos
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo.
Arguments of most conservationists supporting ecotourism have been based upon the views that it is environmentally friendly as a resource-use and that receipts from it can counter demands to use the natural resources involved for more extractive economic purposes.  But wildlife-based ecotourism can also have positive impacts in itself on the willingness of tourists to pay for wildlife conservation, strengthen the pro-conservation attitudes of tourists and foster personal actions by them which contribute to wildlife conservation.  These aspects are explored in this article on the basis of a survey of tourists visiting Mon Repos Beach near Bundaberg, Queensland for the purpose of watching marine turtles.  The results enable several of the conservation...

Glow Worms as a Tourist Attraction in Springbrook National Park: Visitor Attitudes and Economic Issues
Provedor de dados: 31
Autores: Wilson,   Clevo; Tisdell,   Clement A.; Merritt,   David.
Insect-based tourism mainly caters to a niche market, but its popularity has been growing in recent years.  Despite its popularity this form of tourism has remained under-researched and in a sense its contribution to the tourism industry has gone mostly unnoticed. This paper reports the results of a study undertaken on one form of popular insect-based tourism, namely glow worms.  The study was undertaken in Springbrook National Park (Natural Bridge section) southeast Queensland, which has one of the largest glow worm colonies in Australia that attracts thousands of visitors each year.   A study of this form of tourism is important and useful for several reasons. It is important to understand this hitherto under-studied tourism activity to determine the...

Comparative Public Support for Conserving Reptile Species is High: Australian Evidence and its Implications
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo; Swarna Nantha,   Hemanath.
This paper investigates factors influencing the public’s support for conservation of tropical reptile species in a focal group drawing on Australian data and an experiment involving a sample of the Australian public. The influences of the likeability of the species, their degree of endangerment, ethical considerations as well as knowledge are examined and found to be important. Likeability is found to be much less important than the existing literature suggests. This is highlighted by comparing the likeability of the focal group of reptiles with that for a group of birds and a group of mammals with differences in willingness to pay for their conservation.

What role does knowledge of wildlife play in providing support for species' conservation
Provedor de dados: 31
Autores: Wilson,   Clevo; Tisdell,   Clement A.
Conservation of biodiversity is a complex issue. Apart from the creation of nature reserves, there is a plethora of other factors that are part of this complex web.  One such factor is the public knowledge of species. Since public funding is imperative for the conservation of species and creation of reserves for them it is important to determine the public’s awareness of species and their knowledge about them. In the absence of such awareness and knowledge, it is possible that the public may misallocate their support. In other words, resources may be provided for species that do not need support urgently.  We show how availability of balanced information about species helps the public to make rational decisions and to allocate support (e.g. monetary) to...

Does Ecotourism Contribute to Sea Turtle Conservation? Is the Flagship Status of Turtles Advantageous?
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo.
There is little doubt that marine turtles are a flagship species for wildlife tourism.  In some cases, this has turned out to be liability for sea turtle conservation, but in other cases, where for example turtle-based ecotourism has been developed, it has made a positive contribution to turtle conservation.  Examples of both cases are given.  Particular attention is given to the development of turtle-based ecotourism at Mon Repos Beach near Bundaberg, Australia.  This development is set in its historical context and its contribution to conservation is discussed.  Headstart projects for sea turtles in Sri Lanka are a tourist attraction.  While they are promoted as having positive conservation consequences and a survey indicates that visitors are on the...

World Heritage Listing of Australian Natural Sites: Tourism Stimulus and its Economic Value
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo.
Australia has 14 areas inscribed on the UNESCO World Heritage list, on the basis of their globally outstanding natural and in some cases also cultural values. Many regard listing as prestigious and believe that it acts as a signalling device like a brand name. But to what extent and in what ways does the extra prestige bestowed by this listing translate into increased economic value for listed properties? This article deals with two main aspects of World Heritage listing. First, examines the hypothesis that World Heritage listing increases tourist visitation numbers, and available international visitor time-series data are examined to provide empirical evidence. It is found that although visitor numbers are likely to increase as a result of World Heritage...

Environmental and Pro-Social Norms: Evidence from 30 Countries
Provedor de dados: 31
Autores: Torgler,   Benno; Frey,   Bruno S.; Wilson,   Clevo.
The paper investigates the relationship between pro-social norms and its implications for improved environmental outcomes, an area which has been neglected in the environmental economics literature. We provide empirical evidence, demonstrating a strong link between perceived environmental cooperation (reduced public littering) and increased voluntary environmental morale, using European Values Survey (EVS) data for 30 Western and Eastern European countries. The robust results suggest that environmental morale and perceived environmental cooperation, as well as identifying the factors that strengthen these relationships, potentially bring about better environmental outcomes.

Public Choice of Species for the Ark: Phylogenetic Similarity and Preferred Wildlife Species for Survival
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo; Swarna Nantha,   Hemanath.
Humans play a role in deciding which species are preserved and which will perish in the current extinction wave. Because of the Similarity Principle, physical attractiveness and likeability, it is argued that public choice would greatly favour the survival of higher-order species at the expense of others. This paper empirically tests this argument by considering a hypothetical ‘Ark’ situation. Results are drawn from surveys of 204 members of the Australian public who were asked whether they are in favour of the survival of each of 24 native mammal, bird and reptile species. The species were ranked by percentage of ‘yes’ votes received. Species composition in various fractions of the ranking was determined. If the Similarity Principle holds, mammals would...

Australian Tropical Reptile Species: Ecological Status, Public Valuation and Attitudes to their Conservation and Commercial Use
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo; Swarna Nantha,   Hemanath.
Five species of reptiles present in tropical Australia are considered in this study. These are the hawksbill turtle (Eretmochelys imbricata); the northern long-necked turtle (Chelodina rugosa); the taipan snake (Oxyuranus scutellatus); the freshwater crocodile (Crocodylus johnstoni); and the saltwater crocodile (Crocodylus porosus).  Background information is provided on the ecological status of each of these species and after outlining their human use (including commercial use) and management in Australia, an experimental survey method is introduced and results from its application are reported and analysed. The survey method involves two serial surveys of a sample of 204 Brisbane (Australia) residents. The first survey is based on the initial knowledge...

Crocodiles Farms and the Management of Saltwater Crocodiles in the Northern Territory: Results of a Survey of NT Crocodile Farmers plus Analysis of Secondary Information
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo; Swarna Nantha,   Swarna.
After outlining some relevant background information about the NT crocodile farming industry and explaining the purpose of our survey of NT crocodile farmers conducted in the first half of 2005, this paper reports the results of the survey. The information received from the survey is supplemented by secondary data and by information from secondary sources. This report covers the location of respondents; the size of crocodile farms; farmers’ stated knowledge of and attitudes towards the NT Crocodile Management Plan; the involvement of farms in the harvesting of crocodile eggs and the costs involved; views of crocodile farmers about whether the NT Crocodile Management Plan encourages landholders to conserve crocodiles and their perceptions of the benefits to...

Economics of Wildlife Tourism
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo.
After introducing the importance of the topic, we examine the economic impacts of wildlife tourism on income and employment as an indicator of the importance of this form of tourism.  While such indicators can be important politically and to particular interest groups, they are shown to be an inadequate guide to the economic use and conservation of resources, including wildlife used in tourism.  One reason for this (amongst others) is that total economic value must be taken into account in determining economic resource use and this is shown to be quite important in the case of wildlife species.  Empirical procedures, such as use of the travel cost method and stated preference methods (for example, contingent valuation) are outlined and the way in which...

Information and Wildlife Valuation: Experiments and Policy
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo.
An experiment involving 204 residents of Brisbane, Australia is outlined and the results are reported and analysed. Two consecutive surveys of the respondents provide data about their stated knowledge of 23 wildlife species present in tropical Australia, many of which exclusively occur there. In addition, these surveys provide data about the willingness of respondents to pay for the conservation of those species belonging to three taxa: reptiles, mammals, and birds. The respondents’ stated knowledge of the species is compared with their willingness to pay for species’ conservation, and relevant inferences are drawn. When the respondents’ knowledge of the species is experimentally increased in a balanced way, it is found to result in more dispersion...

Public Valuation of and Attitudes towards the Conservation and Use of the Hawksbill Turtle: An Australian Case Study
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Swarna Nantha,   Hemanath; Wilson,   Clevo.
Managing hawksbill turtle populations for use and conservation requires (i) adequate scientific understanding of their population status and dynamics and (ii) consideration of the public’s attitudes to this species. This study employs experimental surveys to assess the Australian public’s attitudes towards the hawksbill turtle, their knowledge of it, their views about its sustainable commercial harvesting, and their support and financial contribution for the species’ conservation. Contingent valuation reveals that the Australian public’s willingness to contribute to the conservation of the hawksbill turtle is high even in comparison to threatened Australian bird and mammal fauna. Most of this stated contribution is based on the intrinsic (non-use) value...

Visitor Profiles and Environmental Attributes, especially of Birds, Attracting Visitors to Lamington National Park: Tourist Attitudes and Economic Issues
Provedor de dados: 31
Autores: Tisdell,   Clement A.; Wilson,   Clevo.
Uses a sample of 622 day and overnight visitors to the O’ Reilly’s/Green Mountains site of Lamington National Park, Queensland, Australia, to identify their socio-economic and other pertinent characteristics and the main reasons and attributes that attract them to the site.  Particular attention is given to birds and their attributes as attractions.  The primary economic injection accruing locally as a result of visits is examined and the difference that the presence of birds makes to local expenditure by visitors is explored.  The extent of support for and objection to the introduction of a fee for entering Lamington National Park is estimated. The many suggestions received from visitors for environmental improvements at this site are discussed.  It is...
