A Global Map of Coastal Recreation Values: Results From a Spatially Explicit Based Meta-Analysis

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 biodiversity richness), geo-climatic factors (temperature and precipitation), as well as sociopolitical characteristics, such as the political stability index. In this context, the proposed meta-analytical valuation exercise explores the spatially explicit dimension of the values building upon Geographic Information System (GIS) tools. GIS are relied upon for the spatial characterization of the valued ecosystems, the determination of the role of spatially explicit variables in the meta analytical value transfer model, as well as for the value transfer exercise. The GIS characterization is observed to be extremely significant in explaining the spatial diversity of the estimates values and underlying explanatory factors. The resulting integrated valuation framework constitutes a worldwide première and it results in the first global map of the recreational value of coastal ecosystems. We argue that the presented global map may play an important role in studying the prioritization for the conservation of coastal areas from a social perspective.Built Coastal Environment, Natural Coastal Environment, Ecosystem Service Valuation, Geographic Information Systems, Mapping Ecosystem Values, Marine Biodiversity, Scaling up, Spatial Analysis, Spatial Economic Valuation, Value Transfer

Measuring the economic benefits of protecting the Parque Natural do Sudoeste Alentejano e Costa Vicentina from commercial tourism development : results from a contingent valuation survey

This paper focus on a contingent valuation application as to measure the value that the Portuguese households are willing to pay for the recreation and biodiversity benefits provided by a Natural Park in Portugal. A national survey was designed and implemented. It gathered 1678 respondents and focus on three tourism development policy options for the Park. We refer to (1) the Wilderness- Area commercial tourism development scenario; (2) the Recreational-Area commercial tourism development scenario and, finally, a scenario version which is characterized by the tourism development of both Wilderness and Recreational Areas of the Natural Park. The results show that the Portuguese evaluate the Wilderness-Area and the Recreational-Area differently. In particular, the Portuguese show a higher willingness to pay for preserving the Wilderness-Area free from any commercial tourism development. However, we find no statistical difference between the willingness to pay for the Wilderness-Area and the willingness to pay for the Wilderness-Area jointly with the Recreational-Area. The last result can be interpreted as a consequence of the lack of credibility of the protection scenarios or, more interestingly, as pointing to the eventual presence of warm glow in the stated willingness to pay responses.financial support of the Calouste Gulbenkian Foundation, the European Commission, and the Portuguese Institute for the Conservation of Nature.info:eu-repo/semantics/publishedVersio

Towards the Optimal Management of the Northeast Arctic Cod Fishery

The objectives pursued by governments managing fisheries may include maximizing profits, minimizing the impact on the marine ecosystem, or securing employment, which all require adjusting the composition of the fishing fleet. We develop a management plan that can be adapted to those objectives and allows the regulator to compare the long-run profits between the various management options. We apply the model to the case of Northeast Arctic cod, and estimate the cost and harvesting functions of various vessel types, the demand function, and a biological model to provide key insights regarding the optimal management of this valuable fish species.Built Coastal Environment, Natural Coastal Environment, Ecosystem Service Valuation, Geographic Information Systems, Mapping Ecosystem Values, Marine Biodiversity, Scaling up, Spatial Analysis, Spatial Economic Valuation, Value Transfer

Economic Valuation of Oceanographic Forecasting Services: A Cost-Benefit Exercise

This paper provides an assessment of the economic value of the oceanographic services provided by the Mediterranean operational forecasting system, MFSTEP. The main purpose of this exploratory study is to carry out a cost-benefit analysis for different development scenarios, by comparing the costs associated with the project implementation with the private benefits that arise from delivering its products on the market. As far as the costs are concerned, a total cost assessment has been performed by identifying, classifying and estimating the wide range of inputs that have been allocated both to the project development and maintenance. Against this context, a cost questionnaire has been designed and administered to all MFSTEP partners. In addition, the study focuses on an end-users analysis in order to examine end-users’ attitudes and interests for the forecasting products, their needs and satisfaction. As before, we make the use of a survey. Finally, this questionnaire is characterized by exploring the use of the contingent valuation approach so as to address and estimate the private benefits derived from the provision of the MFSTEP products. Estimation results show that the mean willingness to pay for accessing the forecasting products amounts to 65 euro per download. Cost-benefit analysis reveals that, from a market perspective relying on the profit maximisation, a total of 163 downloads per day are required for total maintenance costs recovery, whereas 90 downloads per day are required to recover personnel maintenance costs. Finally, 33 downloads per day are required so as to recover durable equipment maintenance costs.Cost-Benefit Analysis, Contingent Valuation, Survey Design, Willingness to Pay, Cost Assessment, Observing and Modelling Oceanographic System

The Profile of a “Warm-Glower”: A Note on Consumer’s Behavior and Public Policy Implications

The paper focuses on the ongoing debate on non-market valuation, including the valuation environmental goods, and the opportunity to use contingent valuation for policy guidance. In fact, contingent valuation critics argue that reported willingness to pay answers do not reflect real economic preferences and, for this reason, should not be used in cost-benefit analysis The attempt to contravene such critique finds many supporters. This paper starts from the latter stream of research and adds two original contributions. First, it sheds light on the individual warm glow motivational profile, exploring the empirical relationship between individual’s socio-economic characteristics and warm glow. Second, it discusses some implications of the presence of warm glow for public policy.Economic value, Contingent valuation, Willingness to pay; Latent factor, Consumer motivations, Warm glow, Ego driven warm glow, Social oriented warm glow, Public policy design

Is the Value of Bioprospecting Contracts Too Low?

In order to regulate the proliferated bioprospecting and protect the biological diversity in the source countries, the Convention on Biological Diversity (CBD) established a legal framework for the reciprocal transfer of biological materials between the interested parties in bioprospecting activities, subject to the Prior Informed Content (PIC) principles and a set of mutually agreed items on equitable sharing of benefits (CBD 1992, Bhat 1999; Ten Kate and Laird 1999; Dedeurwaerdere 2005). Although interesting and valuable to the cause of conservation, there is a feeling that the ‘price’ being paid under these arrangements is too low. Somehow ecologists argue that, surely, these materials have a greater value than the few million dollars being paid to national conservation organizations for the protection of the areas where the material are located. In this paper we seek to understand better how a biodiversity resource’ use value in production is determined, and how the real value is obscured by the fact that the resource is largely open access. We attempt to analyse how special arrangements, set op top of a basic framework in which the resource open access is limited in what it can achieve and in the ‘price’ that will emerge from any transaction between the buyers of the rights and the sellers of the rights.Access and Benefit Sharing, Convention for Biological Diversity, Bioprospecting Contract, Genetic Resource, Open Access and Welfare Analysis

Valuation of Linkages between Climate Change, Biodiversity and Productivity of European Agro-Ecosystems

It is clear that climate change involves changes in temperature and precipitation and therefore directly affects land productivity. However, this is not the only channel for climatic change to affect agro-systems. Biodiversity is subject to climatic fluctuations and in turn may alter land productivity too. Firstly, biodiversity is an input into agro-ecosystems. Secondly, biodiversity supports the functioning of these systems (e.g. the balancing of the nutrient cycle). Thirdly, agro-systems also host important wildlife species which, though not always, play a functional role in land productivity, nonetheless constitute important sources of landscape amenities. The present paper illustrates a unique attempt to economically assess this additional effect climate change may imply on agriculture. We first empirically evaluate changes in land productivity due to climatic change effect on temperature, precipitations and biodiversity. Then we estimate the economic cost of biodiversity impact on agro-systems. Our key finding is that climate-change-induced biodiversity impact on European agro-systems measured in terms of GDP change in year 2050 is sufficiently large to deepen the direct climate-change effect in some regions and to reverse it in others. Different economies show different resilience profiles to deal with this effect.Climate Change, Biodiversity, Agro-Ecosystems

Comparing Tax and Tax Reallocations Payments in Financing Rail Noise Abatement Programs: Results from a CE valuation study in Italy

The paper examines the use of choice experiments (CE) to assess the economic value of alternative rail noise reduction interventions on the so-called Brennero railway, Italy. The novelty of this paper is threefold. To our knowledge, this is the first study on the valuation of noise conducted in Italy and it is the first example of CE applied in the field of rail noise valuation. Second, we consider not only the economic value assessment of noise reduction but also how this reduction is achieved, ranging from policy instruments such as barriers or train technology. Third, the paper provides an original contribution in the valuation literature since we test formally the econometric robustness of the CE estimates under three payment vehicles. In fact, we consider (a) a special regional tax, (b) reallocation of financial resource within the provincial budget on the public transport sector, and (c) reallocation of financial resource of the provincial budget from the administration and entertainment sector. Test results are mixed. Welfare analysis and policy implications of valuing rail noise reduction programs using different payment vehicles are discussed.Choice Experiment, Noise Abatement, Tax, Tax Reallocation, Formal Testing, Welfare Analysis

An Economic Model for Bioprospecting Contracts

This paper explores the use of a micro-economic model to analyse the provisions and parties of bioprospecting contracts. It focuses on the pharmaceutical industry as the representative biodiversity buyer, presenting an original theoretical framework that explains the main contract characteristics or stylised facts. Against this background, it considers the main contractors involved in these private contracts, i.e. biodiversity sellers and biodiversity buyers, analysing both the magnitude and distribution of the respective payoffs. Particular attention is devoted to the different, mixed impacts of bioprospecting contracts and patenting on social welfare. The positive welfare impacts delivered by bioprospecting contracts are associated with the potential discovery of a new drug product, i.e. productivity gains, non-monetary benefit-sharing or transfers and royalty revenues. The negative welfare impact results from the legal creation of a monopoly and the related well-known effect on the consumer surplus. Finally, the potential redistribution effects are limited, and a potential enforcement of this objective may jeopardise the desirability of the contracts since this action would lead to a significant increase in the transaction costs.Bioprospecting Contract, Genetic Resource, Biodiversity Buyer, Biodiversity Seller, Patenting, Welfare Analysis, Benefit Sharing
