Trade in ivory is banned under CITES in an effort to protect the African elephant. The trade ban is supported by some range states, most notably Kenya, because they see the ban as an effective means for protecting a ‘flagship’ species, one that attracts tourists and foreign aid. It is opposed by some states, mainly in southern Africa, because their elephant populations are exceeding the capacity of local ecosystems with culling and other sources have resulted in the accumulation of large stocks of ivory. They argue that ivory trade will benefit elephant populations. The question of whether an ivory trade ban will protect elephant populations is addressed in this paper using a dynamic partial-equilibrium model that consists of four ivory exporting regions...

The welfare dimension of the recreational services provided by global coastal ecosystems is examined through a meta-analytical regression-based valuation approach. First, we construct a global, state-of-the-art database of stated and revealed preference estimates on coastal recreation, which includes also the grey literature and with the latest entry updated to February 2010. Second, the profile of each of the 253 observations of our dataset, which correspond to individual value estimates, was further enriched with characteristics of the built coastal environment (site accessibility, anthropogenic pressure, level of human development), characteristics of the natural coastal environment (presence of protected area, type of ecosystem, and marine...

Bella, Giovanni.

The aim of this paper is to present a search model in the field of environmental economics, where so-called clean and dirty producers enter the trading market, both looking for a partner with whom to exchange the goods they are endowed with. The model derived in this paper is rather simple. Nevertheless, it is able to produce a series of interesting results and useful insights, and is conveniently used here as a framework to explain the functioning of Joint Implementation programmes for polluting emissions’ reduction.

Much of the justification for environmental rulemaking rests on estimates of the benefits to society of reduced mortality rates. This research aims to fill gaps in the literature that estimates the value of a statistical life (VSL) by designing and implementing a contingent valuation study for persons 40 to 75 years of age, and eliciting WTP for reductions in current and future risks of death. Targeting this age range also allows us to examine the impact of age on WTP and, by asking respondents to complete a detailed health questionnaire, to examine the impact of health status on WTP. This survey was self-administered by computer to 930 persons in Hamilton, Ontario, in 1999. The survey uses audio and visual aids to communicate baseline risks of death and...

Current government guidelines for the appraisal of coastal defence projects in the UK do not require that non-market amenity benefits to be considered . However, a new option in coastal defence, namely multi-purpose reefs, provides an opportunity to integrate coastal defence with significant amenity provision. This paper reports the findings of a choice experiment study that evaluated the amenity benefits of four alternative coastal defence systems currently being considered for Borth in west Wales. The results indicate that traditional coastal defence options such as timber and rock groynes do not generate amenity benefits, while a multipurpose reef would generate significant benefits in terms of improvements in the visual appeal of the beach, safer...

Paudel, Krishna P.; Caffey, Rex H.; Devkota, Nirmala.

A visitor’s decision to use a particular recreational site is influenced by the individual’s taste as well as the characteristics of the site. For this reason, improved knowledge of the visitors’ interests and factors influencing their choices are vital for both planning and policy formulations in coastal development. This study examines visitor characteristics and desired site specific characteristics in order to determine the factors affecting use of the Louisiana coast for specific recreational purposes. We use a multinomial logit model and internet survey data to evaluate the factors affecting individuals’ decisions to visit coastal Louisiana for a specific use. Results suggest that the major variables affecting the choice of coastal recreational...

An Improved Method for Calibrating Purchase Intentions in Stated Preference Demand Models

Davies, Stephen P.; Loomis, John B..

The Orbit demand model allows the magnitude of the calibration to stated purchase intentions to vary based on the magnitude of the stated quantities. Using an empirical example of stated trips, we find that the extent of calibration varies substantially with less correction needed at small stated trips (–25%) but larger corrections at higher quantities of stated visits (–48%). We extend the Orbit model to calculate consumer surplus per stated trip of $26. Combining the calibrations in stated trips and value per trip, the Orbit model provides estimates of annual benefits from 60% to 111% less than the count data model.

Analysis of Participation in Multifunctional Agriculture: U.S. Rice Farms

Tur Cardona, Juan; Wailes, Eric J.; Dixon, Bruce L.; Danforth, Diana M..

Multifunctional agriculture is particularly fundamental to some working lands conservation policies and programs, such as the Environmental Quality Incentive Program (EQIP), Conservation Security Program (CSP) and Wildlife Habitat Incentive Program (WHIP). Farmers can also be engaged in providing recreational and agri-tourism services such as hunting, fishing, bird-watching, farm tours, petting zoos and hospitality services. Using the Agricultural Resource Management Survey (ARMS) we analyze factors associated with participation in conservation, recreation and agri-tourism activities as a function of farm structure, farm financial measures, production practices, and socio-demographic characteristics of the farm operator. To estimate the functional...

Analyzing Landowner Demand for Wildlife and Forest Management Information

Antarctic tourism: Environmental concerns and the importance of Antarctica's natural attractions for tourists

Munn, Ian A.; Hussain, Anwar; West, Ben; Grado, Stephen C.; Jones, W. Daryl.

Determining appropriate topics and target audiences is essential to design effective educational outreach programs. Based on landowner responses to a mail survey, we determined both the importance and the availability of wildlife and forest management information topics to Mississippi landowners. Combining this information clearly identified the appropriate subject matter for outreach programs-topics important to landowners and for which information was relatively unavailable. The importance of wildlife and forest management information relative to its availability depended on the region, land use patterns, and landowner characteristics, thus demonstrating which segments of the population should be targeted to maximize program impact.

This article provides general background on the development of tourism in Antarctica and environmental concerns raised by it. However, the major part of it reports on and interprets the results from a survey of tourists visiting Antarctica on a cruise ship. Particular attention is given to the socioeconomic profiles of these tourists, their stated level of knowledge of Antarctica before and after their visit, the relative importance to these visitors of seeing different species of Antarctic wildlife and whether or not the opportunity of seeing Antarctic wildlife was of critical importance for their decision to visit Antarctica. The relative valuation by the sampled tourist of features of their Antarctic cruise is explored along with changes in their...

A method of paired comparison is adapted for use in estimating economic measures of value. The method elicits multiple binary choices for paired items in a choice set. Probability distributions and economic values are estimated nonparametrically and parametrically. The method is applied in an experimental context with a choice set composed of four private goods and several sums of money. The sample's median value estimtes for the goods are generally not different than the market prices for these goods. People who are in the market for a good value it higher than those not in the market for the good.

The groundwater resource, the drinking water areas and the surface water quality can be protected by measures, e.g. by reductions of pesticide and nutrient applications, conversion of arable land to grasslands or forests etc. The objective of the paper is to estimate the benefits of groundwater protection by the valuation method choice experiments. This method allows for separate estimation and comparison of the different attributes connected to groundwater protection i.e. the effects on drinking water and surface water quality as compared to the benefits from cleaning and treatment of polluted drinking water to make it suitable for drinking water consumption. The results indicate that the benefits are significant, and that the willingness to pay for...

This paper reports on and interprets the results of a survey of visitors to the Jourama Falls Section of the Paluma Range National Park located in Northern Queensland. It reports, amongst other things, on how much knowledge visitors to the site had about it before their visit, the procedures they adopted in deciding to visit it and how generally they go about deciding to visit tourist sites when on holidays. The results are consistent with those predicted by theories of bounded rationality and behavioural economics. Information is also provided on the value visitors placed on attractions at the Jourama Falls sites, their attitudes to the private supply of tourist/visitor services and facilities in national parks, the importance of wildlife as an attraction...

Within a context of global trade liberalisation and constrained national budgets, agriculture in many countries has proved incapable of sustaining household livelihoods an d socio-economic development in rural areas. The post-war industrial success of several Asian countries has suggested various alternatives for rural development, including tourism for domestic and possibly foreign visitors. After outlining the economic characteristics of rural tourism and its policies, this paper reviews the evolution of government policies in this area in East Asia, including the establishment of "tourist farms" and "pilot scheme" villages in Korea since the 1980s. A field survey of some 200 Korean village leaders and others, undertaken in 2004, is reported as to the...

The urgent need to improve livestock productivity in sub-Saharan Africa in order to keep pace with expected increases in demand for meat and milk is very topical. Breed improvement provides key entry points for increasing productivity in cattle populations. However, there are tendencies for breed improvement programs to focus on single, market driven traits such as milk or meat production in isolation of environmental constraints and broader livestock system functions which cattle assume in developing countries. This potentially leads to genotypes that are not well adapted to the environment and not capable of performing the multiple roles that cattle assume in cattle production systems of developing countries. In developing countries, many important...

This paper presents an optimal control model to analyze reforestations with two different species, including commercial values, carbon sequestration and biodiversity or scenic values. We solve the model qualitatively with general functions and discuss the implications of partial or total internalization of environmental values, showing that internalizing only carbon sequestration may have negative impacts on biodiversity-scenic values. To evaluate the practical relevance, we compare reforestations in the South-west of Spain with cork-oaks (a slow growing native species) and with eucalyptus (a fast growing alien species). We do the analysis with two different carbon crediting methods: the Carbon Flow Method and the Ton Year Accounting Method. With the...

Coastal communities cannot depend on funding from the state or federal government to maintain high-quality beaches that benefit the public and attract tourist revenues. This article investigates the feasibility and efficiency of beach improvement projects at two Georgia barrier islands through the alternative funding mechanisms of general-revenue financing and user fees. Benefits are calculated from observable sources. The analyses presented support beach improvement as an effective policy on both islands under all scenarios considered.

We developed an economic demand model of wildlife hunting and found that sociodemograpahic and ecological characteristics of county are its strong predictors. Result shows that the hunting is not popular among younger generation; and promoting hunting clubs and lease-hunting, recruiting young hunters could be effective policy considerations for retaining/promoting hunting.
