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…

Sunlit surface waters : exploring the photochemical reactivity of dissolved organic carbon

2017

In surface waters, solar radiation can photochemically mineralise the dissolved organic carbon (DOC, a measure of dissolved organic matter, DOM) to dissolved inorganic carbon (DIC). This DIC photoproduction constitutes an essential yet vague flux in the aquatic carbon cycling. The present thesis is based on the empirical assessment of the DOC photochemical reactivity, which was determined as the spectral apparent quantum yields (AQY) for DIC photoproduction. First, AQYs were determined in DOM solutions to quantify the impact of pH and DOM-associated iron. Then boreal lake waters were used for assessing the alteration of DOC photoreactivity due to water quality and catchment property. By sim…

Transformations Accompanying a Shift from Surface to Drip Irrigation in the Cànyoles Watershed, Valencia, Spain

2017

Drip irrigation is widely promoted in Spain to increase agricultural production and to save water. In the Cànyoles watershed, Valencia, we analysed the consequences of change from surface irrigation to drip irrigation over the past 25 years. There were a number of transformations resulting from, or accelerated by, this change including the 1) intensification of well construction causing a redistribution in access to groundwater, water shortages and a lowering of the groundwater table; 2) expansion of irrigation into former rain-dependent uphill areas resulting in increased water use; 3) shift to higher- value monoculture fruit crops, but with associated higher crop water requirements; 4) in…
