| While conventional farming systems face serious problems of sustainability, organic agriculture is seen as a more environmentally friendly system since it favours renewable resources, recycles nutrients, uses the environment’s own systems for controlling pests and diseases, sustains ecosystems, protects soils, and reduces pollution. At the same time organic farming promotes animal welfare, the use of natural foodstuffs, product diversity and the avoidance of waste, among other practices. However, the future of organic agriculture will depend on its economic viability and on the determination shown by governments to protect these practices. This paper performs panel regressions with a sample of Catalan farms (Spain) to test the influence of organic farming... |

| Allocating scare resources for fire management strategies requires information on the extent of economic losses from bushfires and the efficiency of alternatives. Despite the severity of bushfires, there is no agreed approach in Australia for estimating economic losses from fires nor for evaluating the economic efficiency of alternative suppression strategies. The poster proposes approaches to assess the economic effects of bushfires on local and state economies and sets out models to evaluate the economic efficiency of two key bushfire management strategies: presuppression and suppression. The first model arises from questions concerning the value of pre-suppression (before the fire) fuel reduction activities, and the estimation of an economically optimal... |

| 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... |

| The goal of this paper is to analyse the households’ environmental impact in a regional economy, including the household direct impact as well as the impact associated with the production of goods and services of the household demand. Moreover, per capita ecological impacts for each household category according to income level are obtained. We focus on water consumption, and water and atmospheric pollution. The framework is based on a regional SAMEA (Social Accounting Matrix and Environmental Accounts), and vertically integrated environmental indicators using the Leontief model. An application is carried out for the Aragon case. |

| 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... |

| Key policy issues relating to protection of the Great Barrier Reef from pollutants generated by agriculture are to identify when measures to improve water quality generate benefits to society that outweigh the costs of reducing pollutants. The research reported in this paper makes a key contribution in several key ways. First, it uses the improved science understanding about the links between management changes and reef health to bring together the analysis of costs and benefits of marginal changes, helping to demonstrate the appropriate way of addressing policy questions relating to reef protection. Second, it uses the scientific relationships to frame a choice experiment to value the benefits of improved reef health, and links improvements explicitly to... |

| 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... |

| The aim of this study was to estimate the values to protect the health of the Great Barrier Reef (GBR) at the national level and to examine the effects of distance decay on valuation estimates. A split-sample choice-modelling experiment was conducted in six locations: a regional town within the GBR catchment area (Townsville); Brisbane, the state capital approximately 450 km from the southern limit of the GBR; and four other capital cities (Sydney, Melbourne, Adelaide and Perth) ranging from nearly 1,000 km to over 4,000 km from Brisbane. The results suggest that the average WTP across Australian households is $21.68 per household per annum for five years. There was some evidence of distance decay in values. Most decline occurred once outside the home... |
