| The São José Environmental Protection Area (EPA) in the State of Minas Gerais has a rich natural and historical patrimony. However, in spite of its value and of being a protection area since 1981, it has now suffering several degradations. In that sense, the major objective of this work is to value São José EPA with the purpose of supplying subsidies for the elaboration and attainment of public and private projects of preservation or sustainable exploration of the referred asset, as well as for public policy directed to its administration. As valuation method, it was used the contingent valuation through the approach of Hanemann (1984) and the bootstrapping method to obtain a monthly willingness-to-pay (WTP) per family of the municipal districts that... |

| Policy makers are often interested in transferring non-market estimates of environmental values from a ‘source’ study to predict economic values at a ‘target’ site. While most applications of the benefit transfer process involve an opportunistic search for suitable source studies, there are some examples available of more systematic approaches to developing a framework of values for benefit transfer processes. A key issue in developing such a framework is to deal with adjustment factors, where value estimates might vary systematically according to the context of the trade-offs. Previous research has identified that large differences in scope, such as between national and regional contexts, do affect values and hence benefit transfer. The research reported... |

| Ecosystem services generate benefits that enter human consumption either directly or indirectly via their contribution to human production activities. In this contribution, we provide evidence that (i) the demand of peasants for ecosystem services in rural Indonesia depends on relative poverty; and that (ii) the type of reaction to poverty depends on the specific relation of the ecosystem services to peasant production and consumption. In early 2005 a representative choice experiment study was conducted in the Lore Lindu area in Central Sulawesi, Indonesia, to quantify regional economic preferences (marginal willingessto- pay: MWTP) for four different ecosystem services (n=249; rattan and water availability, shading in cacao agroforestry, population size... |

| made in one situation to related circumstances. The benefit transfer process is typically reliant on the availability of a number of source studies which have appropriate levels of reliability and relevance to the issue of interest. However, the limited number of non-market valuation studies to draw on for source values currently limits the benefit transfer process. In this paper, an alternative approach to benefit transfer is outlined where a series of valuation studies were specifically performed to build a reference data base of values for benefit transfer purposes. The choice modelling technique was used to estimate community values for protecting soil, water and vegetation stocks in Queensland, Australia, where both state and regional populations were... |

| La estimación del valor del agua puede hacerse mediante diferentes métodos, de los cuales este trabajo propone el método de precios "quasi-hedónicos". El agua se considera en este trabajo como una variable externa que impacta en el precio diferencial de la tierra, y cuyo valor estimamos para la Cuenca del Guadalquivir. Los resultados nos muestran un valor capital del agua en el rango 2,8 €/m3 a 4,2 €/m3 con un valor más frecuente de 3,46 €/m3, que según el tipo de capitalización empleado nos daría un valor medio de renta del agua entre 0,14 €/m3 (para r=4%) a 0,35 €/m3 (para r=10%). ABSTRACT The valuation of natural resources is a tool used for improving allocation and management of water resources. This research proposes a quasi-hedonic approach as a... |

| RESUMEN: En este trabajo se presenta una comparación entre dos métodos de valoración de preferencias declaradas: la ordenación contingente y el experimento de elección. Se incluye una aplicación empírica en la que se valoran los impactos que una determinada forestación de terrenos agrícolas en Cataluña tendría sobre la función recreativa, de absorción de CO2 y de protección frente a la erosión de los bosques. Los resultados muestran diferencias entre los valores obtenidos a partir de los dos métodos, siendo los del método de elección significativamente mayores. Además, esta divergencia se mantiene cuando se comparan observaciones pairwise obtenidas directamente a través del método de elección con las simulaciones pairwise procedentes de la ordenación... |

| Researchers using stated preference environmental valuation techniques are interested in identifying the extent to which framing effects impact on value estimates. Framing effects occur when the context in which the hypothetical scenarios and tradeoffs put to respondents in an application differ from those that would be important if actual transactions were involved. Because scenarios have to be defined succinctly to respondents, the challenge for researchers is to identify how the particular ‘frame’ used affects responses, and how different groups of respondents may view settings. In this paper, an application of a stated preference technique termed Choice Modelling is reported in the context of pastoral land development in Queensland and the Northern... |

| The first application of choice experiments as an environmental valuation method in Germany clearly demonstrates the potential of this method for the valuation of agriculture's multifunctionality. Choice experiments are a reasonable enhancement of the conjoint analysis as they are capable of calculating the theoretically correct welfare measures in the form of implicit prices. In combination with business and ecological models this allows for the comprehensive valuation of agriculture's multifunctionality in the sense, that in addition to the supply or cost side of land use scenarios the demand or benefit side is accounted for. In this study the integrated ecological and economical valuation of land use scenarios was demonstrated for two different... |
