| Current government guidelines for the appraisal of coastal defence projects in the UK do not require that non-market amenity benefits to be considered . However, a new option in coastal defence, namely multi-purpose reefs, provides an opportunity to integrate coastal defence with significant amenity provision. This paper reports the findings of a choice experiment study that evaluated the amenity benefits of four alternative coastal defence systems currently being considered for Borth in west Wales. The results indicate that traditional coastal defence options such as timber and rock groynes do not generate amenity benefits, while a multipurpose reef would generate significant benefits in terms of improvements in the visual appeal of the beach, safer... |

| Due to its hydro-geological features, the lagoon of Venice is especially vulnerable to climate change. In particular, it is strongly affected by gradual global warming that brings about the so-called ‘acqua alta’ (high water) phenomenon with greater frequency and intensity. In order to protect the city of Venice from the more and more frequent phenomenon of flooding, some protective measures have been adopted. Among them, the system of mobile barriers commonly known as MOSE: however, by separating the lagoon from the Adriatic Sea, it interferes with ship traffic and has negative impacts on port activities. Against this background, the aim of the present work is to provide an estimate of the direct costs of ship traffic interruption due to the functioning... |

| As policy makers, taxpayers and consumers are willing to know the actual contribution of farming to natural and social environment, sustainability and sustainable development arose as key issues in public debates. Sustainability is a multifaceted concept that includes environmental, economic and social objectives and policy makers need information to take effective decisions. Analysts should rank decisional units according to sustainability criteria and should offer to policy makers more and more insights on the different points of view behind the three dimensions of sustainability. Within the current FADN database sustainability indicators have been identified. In some cases estimations have been necessary and in some other cases thanks to allocation of... |

| Agricultural run-off from the Great Barrier Reef catchment area may cause degradation of coral reefs, affecting the tourism sector that relies on healthy reefs for its income generation. A Contingent Behaviour approach is used to determine the effect of reef degradation on demand for recreational dive and snorkel trips, for a case study of the Great Barrier Reef (GBR) in Australia. We assessed how reef degradation affects GBR tourism and to what extent reef-trip demand depends on the visitors' socio-economic characteristics. A count data model is developed, and results indicate that an average visitor would undertake about 60% less trips to the GBR per year, given a combined 80%, 30% and 70% decrease in coral cover, coral diversity and fish diversity,... |

| The Value of a Statistical Life is a key input into the calculation of the benefits of environmental policies that save lives. To date, the VSL used in environmental policy analyses has not been adjusted for age or the cause of death. Air pollution regulations, however, are linked to reductions in the risk of dying for cancer, heart disease, and respiratory illnesses, raising the question whether a single VSL should be applied for all of these causes of death. We conducted a conjoint choice experiment survey in Milan, Italy, to investigate this question. We find that the VSL increases with dread, exposure, the respondents’ assessments of the baseline risks, and experience with the specific risks being studied. The VSL is higher when the risk reduction is... |

| This study extends previous empirical research on land preservation by considering an actual land preservation scheme, the agricultural land reserve in British Columbia, Canada. The reserve was established in 1973 to ensure that development did not occur on the province’s most productive agricultural land. ‘To ensure that local food production is maintained,’ ‘the economic importance of British Columbia’s agricultural sector,’ and ‘to protect the environment’ are the most important factors that underlie support for the reserve. Aggregate, provincewide willingness to pay to maintain the land reserve is substantial, with our most conservative estimate being Can$91.18 million per year. |

| Within the framework of the nitrate directive, member states have the possibility to apply for derogation, i.e. increasing fertilization standards under certain conditions. Several EU regions have made use of this possibility but all in a different way. In 2009, 6 different derogation policies were worked out. This paper focuses on the differences between the applied policies and makes an assessment of the impact of these differences on the application rate of derogation, the manure surplus and the costs to allocate the manure. Based on the MP-MAS model described by Van der Straeten et al. (2010) the different scenarios are applied on a single case area (Flanders) and the economic effects have been simulated. Results show large differences between the... |

| We present a bioeconomic model of three invasive aquatic plants (hydrilla, water hyacinth, and water lettuce) in 13 large Florida lakes, and simulate one-year and steady-state impacts of three control scenarios. We estimate that the steady-state annual net benefit of invasive plant control is $59.95 million. A one-year increase in control yields steady-state gains of $6.55 million per year, and a one-year lapse causes steady-state annual losses of $18.71 million. This model shows that increased control of hydrilla, water hyacinth, and water lettuce is optimal. |
