| As a consequence of Climate Change sea level rise as well as a change in the intensity and propensity of rain are expected in the Basque Country. Valuing the costs and benefits of adapting to these changes becomes an important piece of information for the planning process. This paper develops two methodological frameworks. The first one devoted to estimating the economic impacts to urban areas of an increase in the risk of flooding. The values estimated for the Nervión river in the city of Amurrio (Álava) indicate that the average expected damage will increase in 15 per cent as a consequence of CC (from €56,097 to €64,451). For an extreme episode the total loss could increase to €20 million. The second framework is oriented towards the valuation of the... |

| A respondent’s preference for non-market goods depends not only on the attributes of the goods but also on the respondent’s attitude towards the goods being valued. Accounting for these characteristics may substantially improve the ability of stated choice models to represent preference heterogeneity. In this regard, we analyzed the influence of respondent attitudes on the valuation of river ecosystem quality attributes affected by pulp mill wastewater in two central Chilean watersheds. We applied the Choice Experiment (CE) method to assess preferences on river pollution risk, water quality effects, threatened species and the yield in local fisheries. The payment vehicle was an additional annual charge to the electricity bill. All three... |

| Abstract Human pressure on ecosystems has undesirable impacts on human well-being. After the Millennium Project, much interdisciplinary research has been developed worldwide aiming to understand these impacts on ecosystem flows and processes, and to learn about the costs and the benefits of ecosystem services for production. Soil provides many ecosystem services, since its multi-functionality is the basis for food production, water filtration, nutrient cycling, and other goods essential to life. This article presents the main concepts and classifications of soil ecosystem services and of its functions; the indicators and the methods for assessment, modeling, and valuation of ecosystem services; some recent applications to assess and evaluate impacts of... |

| The objective of this study was to estimate some economic values of Mud Lake, a managed, lacustrine wetland on the Minnesota-South Dakota border. Several outputs of Mud Lake were identified and an economic value was estimated for each. Flood control was valued at approximately $440 per acre, based on dollar damages prevented; water supply, using public utility revenues, was valued at $94 per acre; fish/wildlife habitat, recreation, and aesthetics were valued at about $21 per acre using the Contingent Valuation Method; and corrective expenditures were used to evaluate water quality at a negative per acre value of $180. When capitalized at 6 percent, the estimated total annual value of these four outputs is $6,250 per acre. These values can assist... |

| In the context of the Water Framework Directive, the French Water Agencies were asked to justify exemptions, for disproportionate cost reasons, to the “good water” status in a series of river basins in 2015. The ministry of the Environment and the economists of the Water Agencies agreed on the fact that this justification would be based on cost-benefit analyses. A great number of cost-benefit analyses were carried out on water bodies or groups of water bodies. This article reports on this experience conducted by the French Water Agencies. It highlights the fact that the large majority of restoration projects generated higher costs than benefits. It suggests that the implementation of the Water Framework Directive could be considerably limited by the use of... |

| Mangroves, seagrass meadows, and salt marshes, collectively termed “Blue Forests,” are counted among the most valuable and productive coastal ecosystems on the planet. A recent literature review of the Blue Forest valuation research identified mangroves as the most frequently analyzed of these ecosystems, yet the literature demonstrates several deficits in terms of geographic location of studies, methods used to value the services, and most notably, a lack of valuation for cultural services. To better understand this, we analyzed the studies dealing specifically with mangroves from the original literature review to quantify what has been valued, where, by which methods, and the variation in the published values. We then use this information to synthesize... |

| This study assesses the ex ante economic impact of the establishment of two parasitoids, the scelionid egg parasitoid Telenomus isis Polaszek from West Africa and a virulent strain of the braconid larval parasitoid Cotesia sesamiae Cameron from western Kenya, to control stemborer. Using a Cobb-Douglas production function, it was estimated that yields increased by 28.5% when pesticides were used to control stemborers. The benefit-cost ratio after the establishment of the parasitoids ranged from 1:1 to 777:1, with a net present value of up to US$192 million. The study demonstrates the potential of redistributing parasitoids indigenous to Africa for the control of African stemborers. Because the benefits of biological control are positively scale dependent,... |
