In some Anglo-Saxon countries, such as Australia and the United States, initiatives have already emerged to promote standardized evaluation practices. However, in Italy, this process is still evolving. Since 1994, the International Valuation Standards Committee (IVSC) has been working on various documents to establish uniform evaluation practices globally. These International Valuation Standards (IVS) are gradually gaining recognition in Italy. Through the efforts of organizations like ABI, Tecnoborsa, the Revenue Agency, and professional associations, IVS are being integrated into evaluation practices for credit approval and public administration requirements.

In forest sector several practical applications need to consider the monetary value of social utility for each specific location and forest function. In this framework the aim of the paper is to implement a spatial analysis model able to link a set of methodologies for the quantification of the total economic value of the forests. The main characteristic of the proposed methodology is the achievement of a geographical dataset with high resolution that can be used for both ex-ante and ex-post Cost-Benefit Analysis and the improvement of spatially explicit forest planning and policy. The results of the application show that spatial analysis methodologies allow the aggregation of several variables and also facilitate the introduction of natural capital concepts into environmental decision-making processes. The analysis is implemented and verified in Tuscany region (central Italy).

The importance of the valuation of public goods is growing. In fact, only by determining the economic value of these assets is possible to determine the efficiency of the investments and of the maintenance. The problems in estimating the total economic value relate to two fundamental aspects: the choice and implementation of the more accurate evaluation methodology and the identification of the universe of users. In literature, in fact, the issue of the universe is often resolved by considering the number of potential users (be they the inhabitants of a city, a neighborhood, a street, etc..) and not the actual visitors. This leads to an underestimation or an overestimation of the use value of public goods. The objective of this research is to focus on this issue by proposing a specific methodological approach to correctly estimate the universe of the actual users of different urban green areas of Florence.

The quantification of the compensation payment for expropriation, which is mainly an economic assessment issue, has been not sufficiently studied above all in relation with the complex relationships that it has with the judicial-normative aspects which regulates the expropriation for public purposes. The case of partial expropriation, the economic-estimative meaning of the expression “agricultural value” and the quantification criteria for the compensation payments in the case of building areas represent for sure some of the most relevant issues concerning the quantification of the compensation payment. The aim of this paper is to go in deeper detail on those issues which offer very interesting cues of thoughts. In these sentences the judges propose interpretations of the regulations which are important for the definition of the appraisal question and in the determination of the compensation payment.

It is more and more evident and widespread the separation between the operating evaluation and the theoretic and methodological teaching of the subject. This paper wants to inquiry into the possible reasons that led to this separation between theory and practise through the analysis of the partial expropriation, one of the most frequent estimative cases that the expert has to deal with. This study has the aim of suggesting a methodological framework able to give back the objective criteria, essential for a good estimative advice. This paper tries to identify the separation points between the estimative method and its practical application, starting from the study of what the literature offers on the theoretic subject and going through the analysis of the estimative expertises done in the professional sector.
