Stima della disponibilità a pagare per la salvaguardia di un'area protetta siciliana dagli incendi boschivi
2009
Forest fires are a major concern in the Mediterranean regions and decision-makers devote large financial resources of the overall public forestry expenditure to their management. The research aims to provide an empirical contribution to the knowledge about the economic benefits deriving from fire protection of forest ecosystems. A case study is presented where we measured the TEV of reducing fire hazards to a cork-oak forest localised in a Sicilian protected area, using a dichotomous choice question in a Contingent Valuation Study. The magnitudes of the annual aggregate WTP estimates obtained range from € 32,745 to € 42,953, corrispondent to € 712 and € 934 per hectare, in order to protect …
La valutazione multicriteriale nella pianificazione territoriale: riflessioni teoriche su un caso applicativo
2009
La svolta epistemologica della scienza delle valutazioni ha consentito di ri-fondare una nuova economia e una nuova teoria del valore su processi evolutivi, comunicativi e autopoietici dei sistemi complessi, grazie agli apporti (convergenti) di discipline diverse e solo apparentemente distanti (fisica, chimica, biologia, sociologia, semiotica, ecc.). Questo nuovo approccio culturale è funzionale al superamento delle chiusure autoreferenziali tra la scienza delle valutazioni e la pianificazione, e alla comprensione della complessità dei sistemi territoriali. La gestione della complessità richiede l’impiego della valutazione multidimensionale per analizzare i molteplici elementi che costituis…
Real estate surfaces appraisal
2014
In the appraisal of the market value of the properties are applied two important surface indexes: the market surface ratio of the secondary surfaces and the ratio of the site value to total value (allocation method). The measure of both these indexes can be revealed difficult: the data collection of the surface trade ratio in the market can get different results and in practice often the valuer refolds on the fixed coefficients brought in the handbooks and in the circulars of the public administration; the appraisal of the ratio of the site, especially in the central zones and for ancient buildings, where besides the incidence is higher, is developed extrapolating the ratios from the periph…
L’Allocation Method nella stima delle aree edificabili
2010
The allocation method does value the building areas on the base of the exchange coefficient, but sometimes it is applied in an uncritical way. Following the traditional appraisal is it possible to precise the methodological conditions. The study means to demonstrate that the market value of the building area is obtained multiplying the construction cost by the ratio between the exchange coefficient and its complementary one. The new formulation considers the effective costs and proceeds distribution in the time, with the cash flows analysis, and moreover concurs to express convenience judgments for building area transactions.
The valuation error in the compound values
2013
In appraising the “valore di trasformazione” the valuation error is composed by the error on market value and the error on construction cost. In appraising the “valore complementare” the valuation error is composed by the error on market value of complex real property and on market value of the residual part. The final error is a function of the partial errors and it can be studied using estimative and market ratios. The application of the compounds values to real estate appraisal misleads unacceptable errors if carried out with the expertise.
Land Cadastre in Italy for Sustainable Development: Application to Two Parcels of Land in a Geopark in the Process of Being Defined in Corleone (PA-I…
2020
Geoparks, like all parks, are UNESCO awards for a sustainable management of all resources and therefore also of human life. Environmental emergencies such as climate change, pollution, soil erosion, salinisation, and fires that, together with health emergencies, undermine life on earth, require intervention. The widespread sustainable management of the territory of a municipality, a region, a nation, or all of them (European Union) allows to widen the application of these concepts to reach the limit of a planet that guarantees life for future generations. The work after having exposed the motivations of the geopark (an initiative born by chance), i.e. the surface where the environmental bea…
The Linguistic Landscape of the Valencian Community: A Comparative Analysis of Bilingual and Multilingual Signs in Three Different Areas
2019
During the last decades, the promotion of multilingualism has been key when designing linguistic policies in Europe. Previous research studies have focused on how languages are employed in fields such as education, media, and urban sites, among others. Bearing all this in mind, the aim of this paper is to analyse the linguistic landscapes of three municipalities located in a bilingual region in Spain, that of the Valencian Community. Thus, issues such as language contact, language dominance, and the languages used by a number of institutions on private and public signs were examined. As for the method, over 140 pictures of language signs were taken in order to examine language contact, lang…
Geomorphology of the urban area of Palermo (Italy)
2020
The results of a geomorphological study carried out in the urban area of Palermo are summarized in a thematic map. Field survey, analysis of aerial photographs and topographic maps, consultation of historical documents and maps, stratigraphic and topographic reconstruction from numerous wells and subsoil data, and bibliographic search were performed, in order to display the geomorphological changes produced by man over time in a densely populated area and to define the Anthropocene of the study area. Palermo town rises along large marine terrace surfaces cut by small river valleys and bordered by wide degraded and abandoned coastal cliffs. Over the last 2700 years, this area was affected by…
Bacterial and phytoplankton responses to nutrient amendments in a boreal lake differ according to season and to taxonomic resolution
2011
Nutrient limitation and resource competition in bacterial and phytoplankton communities may appear different when considering different levels of taxonomic resolution. Nutrient amendment experiments conducted in a boreal lake on three occasions during one open water season revealed complex responses in overall bacterioplankton and phytoplankton abundance and biovolume. In general, bacteria were dominant in spring, while phytoplankton was clearly the predominant group in autumn. Seasonal differences in the community composition of bacteria and phytoplankton were mainly related to changes in observed taxa, while the differences across nutrient treatments within an experiment were due to chang…
Retention forestry and biodiversity conservation: a parallel with agroforestry
2013
In forested landscapes two general management systems – retention forestry and agroforestry – have been proposed as potentially efficient components of landscape approaches to ease the conflict between biodiversity objectives and human needs. In two recent reviews, Gustafsson et al. (2012) and Lindenmayer et al. (2012) provide a global overview of current knowledge about the practice and ecological roles of retention forestry. A few years ago, Bhagwat et al. (2008) produced a similar review addressing the role of agroforestry in biodiversity conservation. Here we draw a parallel between research on the ecological effects of retention forestry and agroforestry. We argue that conservation sci…
