La valutazione ex-ante dei PSR 2007-13 in Italia: modelli a confronto
No full textLa ricerca nasce dalla constatazione che, pur in presenza di una indubbia moltiplicazione delle valutazioni dei programmi di sviluppo rurale, non sembra ci sia una simile proliferazione di studi e analisi "delle valutazioni" e in particolare di analisi delle valutazioni complesse come quelle dei Programmi di Sviluppo Rurale (PSR). Attraverso l'analisi e la comparazione dei 21 rapporti di valutazione ex ante dei PSR italiani, si vuole ricostruire il meccanismo della valutazione, con specifico riferimento agli aspetti metodologici, ai modelli e alle procedure adottati dai valutatori. È un esercizio meta valutativo che intende ricomporre il percorso metodologico complessivo adottato dai valutatori. L'interesse principale è sul come i giudizi di valore sono stati ideati, costruiti e concepiti. Il contributo si propone di entrare nel merito del dibattito sulle metodologie poiché pone in evidenza la rilevanza delle metodologie e delle procedure valutative adottate nella prassi valutativa rispetto alla complessità degli oggetti valutativi
Prezzo edonico per le stime rurali: la scelta delle variabili qualitative
No full textThe paper deals with the quantification of the ordinal variables in order to apply Hedonic Pricing Method in real estate appraisal. A comparison between two hedonic models has been carried out. Models have been calculated by means of different quantification criteria of the above-mentioned variables. Outstanding structural (introduced variables) and numerical (coefficients values) differences have been highlighted, pointing out the importance of a careful market survey by which a “reasoned” quantification of the qualitative features can be derived
Wind farms, farmland occupation and compensation: Evidences from landowners’ preferences through a stated choice survey in Italy
Full text linkThe willingness to accept the construction of wind farms on private properties is investigated using a latent class model approach. This type of research is required in view of the frequent conflicts between landowners and system operators, who often pay little in easement compensation. This study highlights the fact that the acceptance of wind farms is a multifaceted issue comprising aspects relating to socioeconomics, farm type, territory, and past experience. In particular, the compensation claimed by landowners depends on the property's size, the number of turbines, the crop, the presence of surrounding wind farms, natural impacts, the landscape configuration, land fragmentation, land agreements, the presence of other wind towers on the property, and past experience with system operators concerning transparency and participation in the siting and planning phases. Stakeholders should take these factors into account to develop energy policies based on clear, and well-structured processes concerning the siting, planning, construction, and management of wind farms, in order to prevent conflict and to benefit the community and environment
Model tree: An application in Real Estate Appraisal
No full textIn the last twenty years in real estate appraisal there has been a growing interest for new and reliable assessment techniques essentially through the introduction of pluriparametric estimate, in particular of linear regression. However, also these techniques seem having not a great deal of adherence to very complex markets, for which the detection of best suited techniques to investigate market segments is necessary. The aim of the research is to test the applicative possibilities of model tree to land market, in order to highlight possible market segments in the original data set not detectable a priori
La stima dell'indennità per servitù di elettrodotto coattivo mediante uno studio del mercato fondiario in Puglia
Full text linkHigh-voltage overhead transmission lines on farmland imply a permanent easement. System operators should compensate for expropriation of land and depreciation of the remaining farm area, but recognize only the former. Therefore, landowners often appeal to the law courts for fairer refunds. This study highlights that the area occupied by plinths and cabins, the height of pylons and the type of intersection are the main sources of depreciation. Moreover, electric transmission lines depreciate the residual farm area, but involving only two narrow strips of land on either side of infrastructures. Finally, the depreciation tends to decrease rapidly as the distance from the transmission line increases
Community preferences in support of a conservation programme for olive landraces in the Mediterranean area
Full text linkThis study focused on the willingness of the Apulian community in Italy to pay for olive landraces in a conservation programme. A choice experiment approach through a latent class model was carried out in order to investigate different characteristics of people that could increase the effectiveness and efficiency of conservation policies by decision-makers. The analysis allowed us to identify three groups of families, each with very different socioeconomic characteristics. Policy implications suggest the need to develop a better knowledge system on the benefits of olive landraces and to implement suitable strategies for better placement of local products in the market
Latent relationships between environmental impacts of cultivation practices and land market: Evidences from a spatial quantile regression analysis in Italy
Full text linkSeveral economic approaches can be carried out for managing the environmental impacts in agriculture, i.e. property and bargaining rights, economic incentives, ecological fees, etc. These approaches can be mainly applied to the cultivation phase or to the markets of the agricultural commodities. However, a further ambit in which the regulatory systems could be useful to trigger sustainable cultivation practices is the farmland market. Hence, this study contributes to the setting of market mechanisms based on incentives or fees related to the environmental impacts of farming practices for reducing the pressures of the production processes on the environmental components. The study, through a hedonic pricing method based on a spatial quantile regression and integrated by an environmental analysis, highlights different trends of land value determinants along the quantiles of the selling prices as the intensity of the cultivation system varies. The results show that the most important value determinants of the vineyards cultivated through the semi-extensive production system are related to the quality of grapes. Conversely, in presence of the intensive production system, the most important value determinants are related to the high yields, which also generate high greenhouse gas emissions, in contrast with the “polluter pays” principle. The results allow the assessment of the implicit marginal prices concerning the impact of the environmental indicator on land value per cultivation system, so as to favour the setting of regulatory monetary strategies able to foster farmers towards cleaner agricultural practices
