A Global Map of Costal Recreation Values: Results From a Spatially Explicit Based Meta-Analysis AgEcon
Ghermandi, Andrea; Nunes, Paulo A.L.D..
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...

A Hybrid Approach to the Valuation of Climate Change Effects on Ecosystem Services: Evidence from the European Forests AgEcon
Ding, Helen; Silvestri, Silvia; Chiabai, Aline; Nunes, Paulo A.L.D..
In this paper we present a systematic attempt to assess economic value of climate change impact on forest ecosystems and human welfare. In the present study, climate change impacts are downscaled to the different European countries, which in turn constitute the elements of our analysis. First, we anchor the valuation exercise in the Millennium Ecosystem Assessment (MEA) Approach and therefore the link between the different forest ecosystem goods and services, including provisioning, regulating and cultural services, human well-being and climate change. Second, climate change is operationalized by exploring the different storylines developed by the International Panel on Climate Change (IPCC) and applied, downscaled, for each of the European countries under...

A Multifunctional Comparison of Conventional versus Alternative Olive Systems in Spain by Using AHP AgEcon
Parra-Lopez, Carlos; Calatrava-Requena, Javier.
Sustainability of agriculture is strongly related to the multifunctional role implicitly or explicitly recognized to it in the framework of the European Union CAP. This multifunctional role entails a multicriteria approach when assessing the performance and value for society of farming systems. Multicriteria assessment of agricultural systems is characterized by the existence of many criteria often conflicting among then, many stakeholders and decision-makers with competing interests, and lack of information. Analytic Hierarchy Process (AHP) is a multicriteria methodology that allows dealing with these problems, in a relatively easy, flexible and economical manner, and therefore it is a potentially useful tool in this field, although its application with...

Abatement and Transaction Costs of Carbon-Sink Projects Involving Smallholders AgEcon
Cacho, Oscar J.; Lipper, Leslie.
Agroforestry projects have the potential to help mitigate global warming by acting as sinks for greenhouse gasses. However, participation in carbon-sink projects may be constrained by high costs. This problem may be particularly severe for projects involving smallholders in developing countries. Of particular concern are the transaction costs incurred in developing projects, measuring, certifying and selling the carbon-sequestration services generated by such projects. This paper addresses these issues by analysing the implications of transaction and abatement costs in carbon-sequestration projects. A model of project participation is developed, which accounts for the conditions under which both buyers and sellers would be willing to engage in a carbon...

Addressing the wicked problem of water resource management: An ecosystem services approach AgEcon
Hearnshaw, Edward J.S.; Tompkins, Jean-Marie; Cullen, Ross.
This paper develops a systematic assessment of the sustainability of ecosystem services provided by rivers impacted by water storage projects. Given the conflicting preferences amongst stakeholders and the incomplete, uncertain and contradictory understanding about river ecology it is recognized that managing water resources sustainably is a wicked problem. In order to address this wicked problem, the methods of multi-criteria analysis and graph analysis are applied, in accordance with integrated water resource management, to assess the potential of investing in water storage projects and explore for sustainable solutions through the construction of an ecosystem services index.

Agricultural land management strategies to reduce phosphorus loads in the Gippsland Lakes, Australia AgEcon
Roberts, Anna M.; Pannell, David J.; Doole, Graeme J.; Vigiak, Olga.
A target to reduce phosphorus flows into the Gippsland Lakes in south-eastern Australia by 40 per cent to improve water quality has previously been established by stakeholders. An integrated analysis at the catchment scale is undertaken to assess the agricultural land management changes required to achieve this target, and to evaluate the cost-effectiveness of these changes. It appears technically feasible to achieve a 40 per cent reduction in P load entering the lakes, but the least-costly way of doing so would require around A$1 billion over 20 years, a dramatic increase in the current levels of funding provided for management. On the other hand, a 20 per cent P reduction could be achieved at much lower cost: around $80 million over 20 years and...

Agri-Environmental Policies When the Spatial Pattern of Biodiversity Reserves Matters AgEcon
Bamiére, Laure; David, Maia; Vermont, Bruno.
The aim of this paper is to compare different policy instruments for cost-effective habitat conservation on agricultural lands, when the desired spatial pattern of reserves is a random mosaic. We use a spatially explicit mathematical programming model which studies the farmers' behavior as profit maximizers under technical and administrative constraints. Facing different policy measures, each farmer chooses its land-use at the field level, which determines the landscape at the regional level. A spatial pattern index (Ripley L function) is then associated to the obtained landscape, indicating on the degree of dispersion of the reserve. We compare a subsidy per hectare of reserve with an auction scheme and an agglomeration malus. We find that the auction is...

An Economic Model for Bioprospecting Contracts AgEcon
Ding, Helen; Nunes, Paulo A.L.D.; Onofri, Laura.
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...

An Interpretative Model of Aquaculture Multifunctionality: A Methodological Framework Definition AgEcon
De Blasi, Giuseppe; Acciani, Claudio; De Boni, A.; Roma, R..
International trade agreements and the new EU CAP targets require the definition of a new type of subsidy, depending on the non-market functions provided by production activities. The aim of the research project reported in this paper is to find a model to reward multifunctionality of aquaculture, defining all the positive externalities it involves and trying to calculate a monetary value for each of these.

Antarctic tourism: Environmental concerns and the importance of Antarctica's natural attractions for tourists AgEcon
Tisdell, Clement A..
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...

Are tourists rational? Destination decisions and other results from a survey of visitors to a North Queensland natural site - Jourama Falls AgEcon
Tisdell, Clement A..
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...

Assessing community values for reducing agricultural emissions to improve water quality and protect coral health in the Great Barrier Reef AgEcon
Rolfe, John; Windle, Jill.
Key policy issues relating to protection of the Great Barrier Reef from pollutants generated by agriculture are to identify when measures to improve water quality generate benefits to society that outweigh the costs of reducing pollutants. The research reported in this paper makes a key contribution in several key ways. First, it uses the improved science understanding about the links between management changes and reef health to bring together the analysis of costs and benefits of marginal changes, helping to demonstrate the appropriate way of addressing policy questions relating to reef protection. Second, it uses the scientific relationships to frame a choice experiment to value the benefits of improved reef health, and links improvements explicitly to...

Assessing national values to protect the health of the Great Barrier Reef AgEcon
Rolfe, John; Windle, Jill.
The aim of this study was to estimate the values to protect the health of the Great Barrier Reef (GBR) at the national level and to examine the effects of distance decay on valuation estimates. A split-sample choice-modelling experiment was conducted in six locations: a regional town within the GBR catchment area (Townsville); Brisbane, the state capital approximately 450 km from the southern limit of the GBR; and four other capital cities (Sydney, Melbourne, Adelaide and Perth) ranging from nearly 1,000 km to over 4,000 km from Brisbane. The results suggest that the average WTP across Australian households is $21.68 per household per annum for five years. There was some evidence of distance decay in values. Most decline occurred once outside the home...

Assessing the Impact of Biodiversity on Tourism Flows: A model for Tourist Behaviour and its Policy Implications AgEcon
Macagno, Giulia; Loureiro, Maria L.; Nunes, Paulo A.L.D.; Tol, Richard S.J..
This analysis provides an example of how biodiversity can be measured by means of different indicators, and how the latter can be used to assess the influence of the biodiversity profile of a region on the tourism flows towards it. Previous studies have considered environmental amenities as one of the determinants of tourism destination choice. The central hypothesis of this paper is that the destination’s biodiversity profile can be considered as a key component of environmental amenities. The main objective of this study is to propose a different perspective on this topic, considering the role of biodiversity on tourists’ choice of destination and duration of stay. Domestic Irish tourist flows have been chosen as a case study. The first step of the...

Assessing the impact of rural policy on biodiversity: High Nature Value Farming in Italy AgEcon
Trisorio, Antonella; Borlizzi, Andrea.
Farming practices and the conservation value of farmland are intimately interconnected. The recent policy debate has shed light on the need to address farming activities towards a more sustainable path, and has advocated for a reallocation of payments towards farming systems that provide public goods. This paper aims to explore likely HNV farms policy needs through the use of HNV farming system indicators.

BEHAVIOURS OF CONSERVATION ORGANIZATIONS AND THEIR ENVIRONMENTAL IMPLICATIONS. Analysis based on New (and not so new) Institutional Economics AgEcon
Tisdell, Clement A..
This article draws mostly (but not entirely) on new institutional economics to consider the likely behaviours of non-government conservation organizations and the implications of these behaviours for biodiversity conservation. It considers how institutional factors may result in behaviour of conservation NGOs diverging from their objectives, including their support for biodiversity conservation; examines aspects of rent capture and conservation alliances; specifies social factors that may restrict the diversity of species supported by NGOs for conservation; considers bounded rationality in relation to the operation of conservation NGOs; and using game theory, shows how competition between NGOs for funding can result in economic inefficiencies and narrow...

Beyond Economic Efficiency in Biodiversity Conservation AgEcon
Gatzweiler, Franz W.; Volkmann, Jorg.
This paper aims at explaining the importance of the democracy stance as compared to the efficiency stance in order to deal with complexity in biodiversity conservation. While the efficiency stance refers to the realm of relatively simple systems, individual rationality, and instrumental values, the complexity stance transcends these boundaries into the realm of complex systems, social rationality and intrinsic values. We argue that the task of biodiversity conservation is impossible to achieve in economically efficient ways, because (a) it is impossible to come to a (fully informed) complete account of all values, not only because it is costly but also because (b) moral values are involved which (by their nature) exclude themselves from being accounted...
