“…Most obviously, studies find different WTP amounts because they value different goods. For studies looking at wildlife and habitat conservation, the specific habitat or species being considered, whether it is unique, and whether it is known to the public is important (Christie et al, 2006). Moreover, whether a charismatic or a rare species is to be preserved can matter (Metrick andWeitzman, 1994, Hanley et al 2003), along with the size of prospective change in the habitat or species.…”

This paper is concerned with the empirical relationship between biodiversity conservation values and income. We use random effects panel models to examine the effects of income, and then GDP per capita, on willingness to pay for habitat and biodiversity conservation. In a meta-analysis, 145 Willingness To Pay estimates for biodiversity conservation where existence value plays a major role were collected from 46 contingent valuation studies across six continents. Other effects included in the meta-analysis were the study year; habitat type; continent; scope as presented to respondents; whether WTP bids were for preventing a deterioration or gaining an improvement in conservation, whether a specific species or specific habitat was protected; whether the questionnaire used a dichotomous choice or an open-ended format; distribution format; and the choice of payment vehicle. GDP per capita seemed to perform as well as an explanatory variable as respondent's mean stated income, indicating that it is wealth in society as a whole which determines variations in WTP. Our main conclusion is that the demand for biodiversity conservation rises with a nation's wealth, but the income elasticity of demand is less than one. JEL Codes: Q2, H4, D6

“…The economic value of mangrove ecosystem services should be evaluated to assist with the future management and conservation mangrove ecosystems. Economic valuation can support the formulation of policies by attaching and the economic value of the preservation of biological resources (Christie et al, 2006). The economic valuation of mangroves involves constructing a hypothetical market because the majority of the ecosystem service functions performed by mangroves provide indirect value and do not imply marketed resources.…”

Mangroves provide multiple benefits for local communities' livelihoods. However, in the Mahakam delta mangroves have declined considerably. This study examines the factors affecting households' willingness to pay (WTP) for mangrove restoration in three villages in the Mahakam delta and determines whether a mangrove restoration project would be viable and should be implemented in the study area or not. The contingent valuation method was applied through a double-bound dichotomous choice format to estimate the WTP for mangrove restoration. The results showed that over 80% of perception of respondents considered the benefits of mangroves were essential that associated with their livelihoods. Local residents tended to be willing to pay more for mangrove restoration when they acknowledged the benefits of mangroves and when they felt that the sustainability of mangrove ecosystems was their responsibility. The benefits transfer method was also used to estimate the costs and benefits of an ongoing mangrove restoration project in the study area. The benefits provided by mangroves, as estimated based on households' WTP, clearly outweighed the costs for the mangrove restoration project. We conclude that mangrove restoration should be implemented in the study area by increasing local communities' awareness and responsibility to protect and manage the mangrove a sustainable.

“…Malgré certains titres provocateurs (Christie et al, 2006), les mesures empiriques de la valeur de la biodiversité et des écosystèmes portent en fait sur des objets concrets et assez variés (gènes, espèces, habitats, fonctions, services) dont le choix est souvent motivé par la finalité de l'évaluation (Goeschl et Swanson, 2007 ;Sarr et al, 2008 ;Loomis et White, 1996 ;Richardson et Loomis, 2009 ;Kassar et Lasserre, 2004 ;Leroux et al, 2009). …”

Mots-clés :biodiversité ; choix collectifs ; évaluation économique ; politiques de conservation ; services écosystémiques.Résumé -L'évaluation de la biodiversité et des services liés aux écosystèmes est actuellement l'objet de nombreux travaux et d'un large débat. Afin de dépasser les oppositions, il importe de comprendre ce que signifie vraiment l'évaluation économique pour en cerner l'intérêt et les limites. Le nécessaire élargissement de la notion de valeur qu'implique une analyse appropriée de ces services a donné lieu à une pluralité de méthodes, parfois durement contestées. L'objet de cet article est de préciser certains termes de ces débats, tant conceptuels que méthodologiques, ainsi que le choix des objets à évaluer, en les resituant par rapport aux objectifs très différents que peuvent poursuivre les évaluations. Keywords:biodiversity; collective choices; economic valuation; conservation policies; ecosystem services Abstract -Biodiversity and ecosystem services valuation: for which purpose, how and with which results? The valuation of biodiversity and ecosystem services is the subject of many studies and extensive debate. To overcome problems of principle, the real meaning of economic evaluation must be clarified in order to identify its advantages and limitations. An appropriate analysis of these services implied extending the concept of value and has given rise to a plurality of methods that may be strongly challenged. The purpose of this paper is to clarify some terms of these debates. There are reasons for being reluctant to give a price index to Nature's services, but its conservation entails costs, at least opportunity costs. Most valuation methods rest upon individual preferences, either revealed by concrete behaviours, or stated during interviews, and this is clearly an issue for items agents are not familiar with or do not perceive clearly the benefits. Finally, valuing biodiversity through ecosystem services might lead to underestimate some major parts of what constitutes biodiversity social value. These issues have to be replaced in relation to the very different objectives that may further the actual valuations. The paper concludes that valuation can offer quite a valuable contribution to conservation policies, but since the relation between biodiversity, ecosystem services and human well-being remains poorly understood, that it is a far too important stake to let economists alone in facing these puzzles.
