National forests and woodlands are some of the environmental public resources that provide a diversity of goods and services to society. Supporting, regulating, provisioning and cultural services are all known to contribute to human well-being. As these services are not traded in regular markets because of the public or semi-public characteristics of the resources involved, their values are largely unknown. However, a deeper knowledge of the related benefits’ value is expected to help to enhance management practices. The research described in this dissertation concentrates on the analysis of the benefits related to recreational activities enjoyed in national forests and in understanding the demand for these environmental services. The research was motivated by the perception that these values are largely unknown, particularly in Portugal. Bussaco National Forest was chosen as the case study area, but the conclusions are likely to be adapted and extended to other national forests. Two non-market valuation techniques, the travel cost method and the contingent behaviour method, are used to estimate the recreational use benefits. The travel cost method, which belongs to the group of revealed preferences techniques, is used to analyse the actual behaviour and enables us to estimate recreational use values in current conditions. The individual version of the method is identified as the most accurate in the present context as we analyse the recreational demand of a forest visited by people living at different distances from it. From the management perspective...

Dissertação de mestrado em Economia e Política do Ambiente; The study focuses on the common trade-offs between nature conservation and economic development, tourism in particular, in the case of Phu Quoc island, Vietnam; this is a problem poor and developing countries are often faced with due to severe budget constraints. Applying methods of economic valuation to non-market goods, the island environmental values are estimated as the direct use for recreational purposes and the indirect use for improving environmental condition. The field data was collected simultaneously through the administration method of a questionnaire online and on-site to tourists while a different questionnaire was applied through face to face interviews to local residents. The travel cost method reveals that the recreational value is equal to over 63 million dollars per year. The contingent valuation outputs the total annual economic values of nature conservation at nearly 1 million dollars to tourists and also reveals that tourists aren’t willing to pay to improve the environmental program in Phu Quoc island. The result confirms the importance of nature as a recreational asset and explores the possibility for local authorities to apply market-based instruments through an environmental tax or a nature conservation fee to different subjects to promote the development of the area while protecting the natural environment.; Este trabalho estuda o compromisso entre conservação da natureza e desenvolvimento económico...

Recently, the sport of ice climbing has seen a drastic increase in popularity. This paper uses the travel cost method to estimate the demand for ice climbing in Hyalite Canyon, Montana, one of the premier ice climbing venues in North America. Access to Hyalite and other ice climbing destinations have been put at risk due to liability issues, public land management agendas, and winter road conditions. To this point, there has been no analysis on the economic benefits of ice climbing. In addition to the novel outdoor recreation application, this study applies econometric methods designed to deal with “excess zeros” in the data. Depending upon model specification, per person per trip values are estimated to be in the range of $76 to $135.

Municipal solid waste management continues to be a major challenge for local governments in both urban and rural areas across the world, and one of the key issues is their financial constraints. Recently an economic analysis was conducted in Eryuan, a poor county located in Yunnan Province of China, where willingness to pay for an improved solid waste collection and treatment service was estimated and compared with the project cost. This study finds that the mean willingness to pay is about 1 percent of household income and the total willingness to pay can basically cover the total cost of the project. The analysis also shows that the poorest households in Eryuan are not only willing to pay more than the rich households in terms of income percentage in general, but also are willing to pay no less than the rich in absolute terms where no solid waste services are available; the poorest households have stronger demand for public solid waste management services while the rich have the capability to take private measures when public services are not available.

"Getting the prices right" is a good starting point but is not sufficient for achieving environmentally efficient outcomes. Other policy interventions are often necessary to complement pricing policies. Moreover, when pricing is not at all feasible, regulatory and command-and-control policies must be used instead. This paper focuses on three interrelated themes at the core of the pricing problem. First, there is the incorporation of non-marketed activities with environmental consequences into aggregate measures of economic performance: the so-called "green-GDP." Second, there is the problem regarding the reliable estimation of the valuation of the shadow prices that properly reflect environmental externalities. Third, there is the issue of full-cost pricing that requires the pricing of environmental externalities for guiding both individual and public decision-making.

This report is the first step in a process toward using environmental damage cost assessments for priority setting and as an instrument for integrating environmental issues into economic and social development. The report provides estimates of damage cost for several areas of the environment: air, water, land and forests, and waste disposal. The estimates should be considered as orders of magnitude and a range is provided to indicate the level of uncertainty. As areas of priority are identified, further analysis will be required for more accurate estimates. Due to data limitations, the damage cost of environmental degradation has not been estimated in several areas: industrial, hazardous, and hospital waste disposal; unsanitary landfills; degradation of natural ecosystems and biodiversity; and groundwater resource degradation and over-extraction. In addition and due to the complexity of the problem, the report only partially captures damage resulting from soil degradation. The report points t the need to further assess and quantify current and potential future damage costs related to those impacts.

La valoración económica de los usos recreativos de los espacios naturales es relativamente reciente en España. La utilización del método del Coste de Viaje (MCV), como herramienta para acometer dicha valoración, ha resultado fértil en la literatura científica reciente tanto en lo que hace referencia a su variante individual como zonal. Este artículo llevará a cabo de manera inicial y novedosa la valoración económica del parque natural del Delta del Ebro a través de la variante zonal para el período 1999-2007. Los resultados obtenidos ponen de manifiesto un aumento en el valor de casi un 60%, pasando de los 4.1 millones de euros en 1999 hasta los 6.5 millones en 2007. Por otra parte, el salto en el valor en el 2005 podría atribuirse a la promoción del parque asociada a la derogación del Plan Hidrológico nacional.; ABSTRACT The economic valuation of recreational use associated to environmental goods is relatively new in Spain. The employment of the Travel Cost Method (TCM), as a tool for estimating this value, has growing in the scientific literature. This paper makes an initial contribution to estimating the recreational value of Delta de l’Ebre natural park, over the period 1999-2007, using the zonal approach.

Randall (1994) argued that the Travel Cost Method, TCM, cannot do what it is supposed to do - generate monetary measures of recreation site benefits for use in Cost Benefit Analysis. Randall argues that what is relevant to recreational decision making is the subjective, and unobservable, price of travel, whereas what TCM uses is the observer assessed cost of travel. Hence, the best that can be expected from TCM is ordinally measurable welfare estimates. This paper formulates ‘Randall’s difficulty’ as an estimation problem and derives some results for that problem. A survey data set and Monte Carlo simulations based upon it, where many of the problems usually attending TCM application are absent, are used to illustrate and quantify Randall’s difficulty. The meaning of, prospects for, and usefulness of ordinal measurement are explored, and the question of the existence of a solution to Randall’s difficulty is considered.; no

The need to save and protect the environmental goods and services against the uncontrolled human consumption and interventions led to the institutionalization and creation of the Conservation Units. And these, in addition to ensuring the conservation of a certain biome's natural patrimony and biodiversity, carry with them environmental, social, economic, cultural values, among others, attributed by people, due to the use and non-use of their environmental goods and services. For the evaluation of the values related to that kind of unit, this work took place in the São Jorge District, City of Alto Paraíso de Goiás, State of Goiás, Brazil, in the Chapada dos Veadeiros National Park (PNCV), with the intention of evaluate the importance of the Conservation Unit in the context of the development of the region, identifying the values that people (residents and visitors) attribute to the Park's set of goods and services and the District surroundings. At first, it became a study case of the elapsed historical context in the region, to analyze the socioeconomic activities developed there since the time of mining, until the tourism arising from the National Park, in order to apprehending the notion of value of the local residents. Then proceeded to a environmental valuing...

Recreation is one of the ecosystem's secondary values of a well conserved natural ecosystem, associated with the direct use individuals make of these natural assets. In this paper we define and estimate the total economic recreation value to visitors of a particular natural area, a national park. An on-site individual observation Travel Cost Model, Count Data distributions, and a version of hyperbolic discounting framework distribution were used to estimate a measure for the present recreation use of the site and the total discounted recreation value for a 50 years period. The empirical estimates of the average representative visitor's present equivalent surplus willingness to pay, based on the impact assumption of closure or loss of access to the park were 123 € per day per visit, and 593 € per each average five days length visit, per visitor. These values suggest that recreation use of nature has a higher value than certain economic activities in the area.

Current institutions, research, and legislation have not yet been sufficient to achieve the conservation level of Nature as required by the society. One of the reasons that explains this relative failure is the lack of incentives to motivate local individual and Nature users in general, to adopt behaviour compliant with Nature sustainable uses. Economists believe that, from the welfare point of view, pricing is the more efficient way to make economic actors to take more environmental friendly decisions. In this paper we will discuss how efficient can be the act of pricing the recreation use of a specific natural area, in terms of maximising welfare. The main conservation issues for pricing recreation use, as well as the conditions under which pricing will be an efficient and fair instrument for the natural area will be outlined. We will conclude two things. Firstly that, from the rational utilitarian economic behaviour point of view, economic efficiency can only be achieved if the natural area has positive and known recreation marginal costs under the relevant range of the marshallian demand recreation curve and if price system management is not costly. Secondly, in order to guarantee equity for the different type of visitors when charging the fee...

The Upper Paraná River floodplain is the last lotic stretch of an ecosystem seriously threatened given that circa 50% of the original ecosystem has been converted into reservoirs. To assess the recreational value of the Upper Paraná River floodplain, 174 tourists were interviewed using the Willingness to Pay - WTP and Travel Cost - TC methods. The annual aggregated WTP attributed by tourists was US$ 122.50 million and the variables which determine the decision in willingness to pay for the Floodplain are: 'consider oneself as a Floodplain natural resources consumer' and 'marital state'. If the single person considers her/himself as a consumer of floodplain natural resources, the WTP increases by a multiplicative factor of 38.8. The value aggregated by the TC method was US$ 234 millions and decreased by zone as the distance increases. Higher income and traveling farther increases the travel cost, which is inversely related to annual trip frequency. The total recreational value (356.5 millions per year) is high and representative since it refers to an environment fragmented by dams and with many anthropogenic effects. Therefore, the progressive changes on the landscape are a threat to local tourism, since half of the visitors are attracted solely by the scenic beauty...

Protected areas are an important part of our society. They provide ecosystem services such as climate regulation and water filtration; they secure critical habitat for wildlife, including many threatened and endangered species; and they also provide a form of recreation through wildlife viewing, photographing, hiking, and camping. Eliciting the economic benefits of these protected areas is important to ensure they are properly considered in policy and decision making. But because no markets for these services currently exist, protected areas are often undervalued when compared to alternative land use policies. As lands are put under more pressure from population and economic growth, it is critical that the benefits derived from protected areas are fully understood. Therefore, non-market valuation techniques have been developed to estimate these benefits. Relatively few environmental valuation studies, however, have been conducted in developing countries to date. Here, I apply one such valuation method, the travel cost method (TCM) to estimate the recreational benefits of Tanzania’s protected areas to East African citizens. Data were collected from visitors through an on-site intercept survey in Arusha National Park (ANP) during the summer of 2012 . The recreational value...

This study estimates the change in aggregate consumer surplus associated with increased freshwater supply into two South African estuaries, namely, the Klein and the Kwelera. The estimation entailed the application of a contingent behaviour, single-site Clawson-Knetsch travel cost model. The value estimates derived reflect the benefit of improved freshwater supplies into the estuaries in question over the status quo. In a survey, a questionnaire was administered face-to-face to 240 households at the Klein Estuary and 231 households at the Kwelera Estuary during the period between December 2005 and April 2006. It was deduced that in 2006 the marginal recreational value of freshwater inflow into the Klein Estuary was 5.7 cents/m³ (ZAR0.057/m³) and into the Kwelera Estuary 1.1 cents/m³ (ZAR0.011/m³).
