A bioeconomic model for estimating the benefits of acid rain abatement to Salmon fishing: a case study in South West Scotland

The United Kingdom, under the Large Combustion Plant Directive of the European Community, is committed to cutting sulphur dioxide (SO2) emissions by 60% of 1980 levels by the year 2003. In order to justify this action and to support new decisions on further emission reductions, policy makers require knowledge of the economic benefits of abatement. Benefit estimates for the recovery of freshwater fish populations present difficulties since the effect of reduced acid deposition on environmental processes is complex and because fishery records are often inadequate or absent. This paper predicts the economic benefits of acid rain abatement to the rod and line salmon fishery of Galloway, South West Scotland. It achieves this by linking output on long term changes in water chemistry and fish population status from MAGIC, a process based catchment model for acidification, with catch and market value data. Predicted increases in the market value of the fishery are presented and the role of the model in economic analysis of environmental policy discussed

Landscape as a tourism resource: a case study in the Northern Region of Portugal

This article aims to emphasize the importance and function of the landscape as a tourism resource, increasingly valued in tourism destinations. The landscapes are the subject of discussion and the object of sensitization to the valorisation and preservation in recent years. Nowadays, the landscape has acquired a greater appreciation on the part of society, because it is often assigned values representative by one or more sets of individuals. The valuation of the landscape allowed to create regulations and legislation related to its preservation and maintenance. In this sense, this research focuses on the importance of the landscape as a tourism resource and its impact on the motivation and preferences of the tourist in the northern region of Portugal as a tourism destination. Results demonstrate the preference about “coastal landscape”, followed by “mountain landscape”; also, Porto Metropolitan Area is notably the most visited region in the North of Portugal, followed by the Douro region. Most respondents agree that they usually include viewpoint in their journey plans, emphasizing “natural viewpoints”.info:eu-repo/semantics/publishedVersio
