In this paper we examine the content of farm animal biodiversity conservation measurescurrently under implementation in the European Union (EU), as a result of the application of EC Regulations 1257/99 and 1750/99. We surveyed 69 Rural Development Plans (RDPs) set up in EU Member States. Our analysis focuses on six livestock mammalian species: asses, cattle, goats, horses, pigs, and sheep The starting point for our investigation is the Domestic Animals Diversity-Information System (DAD-IS) FAO database which monitors the status of breeds in the world. We compare breeds included in the DAD-IS FAO database with breeds covered by the various RDPs. The analysis highlights that many breeds at risk of extinction according to FAO are not included in the RDPs. The analysis also indicates that the main efforts of the RDPs are devoted to preserving local cattle and sheep breeds. As concerns the financial aspects of livestock biodiversity measures, we note that the payments offered to farmers do not take into account the different probabilities of extinction associated with each breed in each country. Furthermore, we observe that payments do not meet all of the relevant criteria stated in the EEC Regulations. In many cases, we observe that, in spite of the Union's support to farmers, it still remains unprofitable to rear local breeds. These anomalies suggest the need for a revision of the current EU supporting measures related to the conservation of livestock biodiversity. Finally, by using FAO indicators on the current population size of each breed, we estimate the level of expected public expenditure necessary to ensure the upgrading of breeds from their

The aim of the paper is twofold: to carry out a contingent valuation study of "Napoli Musei Aperti", a cultural public good provided by the city of Naples, and to explore some alternative schemes of cultural policy. The paper is divided in two parts. In the first one some results from the contingent valuation study are presented. In the second one the use of the contingent valuation as a policy instrument in the public cultural sector is discussed.

Utilizing the random utility and random profit difference approaches, we develop a theoretical model that explains why farmers may require a premium in excess of the decrease in profits to adopt a conservation plan. Identification of this risk premium can aid the government in addressing approaches to lowering the costs of encouraging farmers to adopt the conservation programs. Previous work done in this area has not successfully identified this premium We estimate this premium using survey of farmers in conjunction with predictions of changes in production costs. To increase the efficiency of the econometric analysis of survey responses, we use the so-called "one-and-one-half-bound" (OOHB) elicitation format. Furthermore, to test the sensitivity of our estimation results to functional form and distributional specifications, we compare the results utilizing parametric, nonparametric, and semi-nonparametric econometric approaches.

AbstractRock climbing is an increasingly popular recreation activity worldwide, nevertheless there are only few studies that estimate the demand for it. In this article the Kuhn–Tucker approach is used to estimate the demand for rock climbing in Sicily, the recreation value of different climbing sites, and the welfare impact of reducing injury risk. In modeling the demand for climbing we account for the heterogeneity of preferences. We find that decreasing the level of injury risk generates remarkable welfare gains to climbers. This is the first study we know of that provides a welfare measure of risk reduction in rock climbing and one of a very few studies in environmental economics that uses a revealed preference approach to estimate a welfare measure associated with a reduction in risk.

Abstract. Wildfires are key not only to landscape transformation and vegetation succession, but also to socio-ecological values loss. Fire risk mapping can help to manage the most vulnerable and relevant ecosystems impacted by wildfires. However, few studies provide accessible daily dynamic results at different spatio-temporal scales. We develop a fire risk model for Sicily (Italy), an iconic case of the Mediterranean Basin, integrating a fire hazard model with an exposure and vulnerability analysis under present and future conditions. The integrated model is data-driven but can run dynamically at a daily time step, providing spatially and temporally explicit results through the k.LAB (Knowledge Laboratory) software. This software provides an environment for input data integration, combining methods and data such as geographic information systems, remote sensing and Bayesian network algorithms. All data and models are semantically annotated, open and downloadable in agreement with the FAIR principles (findable, accessible, interoperable and reusable). The fire risk analysis reveals that 45 % of vulnerable areas of Sicily have a high probability of fire occurrence in 2050. The risk model outputs also
include qualitative risk indexes, which can make the results more understandable for non-technical stakeholders. We argue that this approach
is well suited to aiding in landscape and fire risk management, under both
current and climate change conditions.
