| Assigning an economic value to a given environmental asset has helped conservation proposals, and valuing these assets at levels comparable to market rates facilitates the establishment of environmental policies. Thus, this research aimed to assess the value of the species Myracrodruon urundeuva Allemão, using the method of contingent valuation to determine the maximum willingness to pay of frequent visitors to the Caruaru Fair, located in northeastern Brazil. Our results show that most interviewees agreed to participate in proposals to support species conservation, although the average willingness to pay (WTP) was relatively low compared to other surveys conducted in Brazil. However, a significant number of the interviewees had exceptionally low monthly... |

| ABSTRACT The immature leaves of the buriti palm (Mauritia flexuosa) are widely harvested in the municipality of Barreirinhas, Maranhão, for the production of handicrafts, which are sold to locals and tourists. The increasing demand for these artisanal goods is stimulating the emergence of an informal market for immature buriti leaves, leading to an intensification of their extraction and resulting in negative effects on local buriti palm populations and the ecosystem. Thus, the objective of the present study was to assess the environmental value of the buriti palm tree based on the maximum willingness to pay (WTP) for its conservation, using the contingent valuation method. Among the respondents, 99.74% reported that the palm species should be protected... |

| Monetary contributions might not be appropriate welfare measures in contingent valuation (CV) when household incomes are very low. In such cases, willingness to pay (WTP) is restricted by a household's ability to reduce its consumption of other goods to pay for the environmental good under valuation. Beneficiaries, however, may be willing to contribute their time to work on a project instead of paying money. In this context, we assess the benefits of ecosystem services restoration in a rural area of high conservation value in central Chile, using a CV study that includes two WTP questions, one for cash and another for labor payments. The results indicate that labor payments in the form of a number of working hours per week were highly accepted among... |

| The aim of this study is to determine the preferences and willingness to pay for organic pears among high-income people in the Metropolitan area of Santiago de Chile. To do this, the methods of conjoint analysis and contingent valuation were used. The study population was the Santiago Metropolitan Region in Chile. For the conjoint analysis, four attributes of pears were studied (variety, price, body, and production). For contingent valuation, subjects received a description of the organic production process vs. the conventional process and were then asked about their willingness to pay more per kilogram for pears produced organically. Both methodologies revealed a positive willingness to pay for pears. The estimated utility of each attribute level... |

| The contingent valuation method was employed to assess the benefts of recovering the Laguna Grande de San Pedro de La Paz in Chiles Bío-Bío region and to analyze the possible existence of an embedding effect. Our results indicate that there is not a perfect part-whole valuation effect and that there is an imperfect substitution relationship between the two analyzed projects. In addition, when assessing the joint construction project of a main sewer and a recreation park on the north hillside of the lagoon, we determined that households were willing to pay an average monthly amount of $6,114 for the associated beneft of the environmental improvement. This amount would contribute $ 358,977,396 per month to the project and a total value of $4,307,728,752.... |

| Se realizó un análisis de estudios de caso que demostró diversos problemas sociales en los parques urbanos del mundo, destacando un problema histórico de exclusión de grupos vulnerables como mujeres, hombres homosexuales, etnias/razas y personas con capacidades diferentes. Bajo una óptica de equidad e inclusión se sugiere que los planificadores de parques contemplen una visión paisajística que permita el desarrollo de un Sistema Integral de Espacios Verdes Citadinos que comprenda esquemas de participación ciudadana y herramientas ecológicas, sociales y económicas. Una de estás últimas, es la valoración económica a través de modelos de disposición de pago y que puede ser aplicada en análisis beneficio-costo bajo una perspectiva que integre aspectos sociales... |

| 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... |

| The recent food crises in Europe have raised public concerns about the quality and safety of food. The growing concern among the consumers towards food safety issues has increased the demand for quality attributes. Most quality properties of food products can be considered as credence characteristics, quality of which cannot be inferred before the purchase, and sometimes not even after the purchase. The aim of this study is to evaluate, both qualitatively and quantitatively, the value of new information about and the information systems set for credence characteristics of beef. Economics of information is the theoretical framework. The quantitative approach focuses to measure the ex ante value of credence characteristics, and the method of contingent... |

| This paper presents a case study on the development and implementation of a decentralised and outcome-based agri-environmental payment scheme in a project region in central Germany. A research group from Goettingen University together with local actors designed the scheme which complies with the European Union’s Common Agricultural Policy. The core of the programme is the creation of a market for ecological goods, in this case: of plant diversity standards in agriculture. Supply is provided by the local farmers, who, in an open competitive bidding, offer to produce as much as they are willing to of the commodity in question. The local population has to be seen as the beneficiary of these environmental goods. In the project, it is represented by a Regional... |
