In this sub-section and once recognized abandonment as a social fact, an analytical schema based on parameters (Sect. 3.1), factors (Sect. 3.2), reasons (Sect. 3.3), policies (Sect. 3.4) is proposed. The aim is to have a richer "toolbox" to critically revisit the issue as a complex problem.
Parameters and IndicatorsThere are at least five operative parameters (and relative indicators) to detect "abandoned buildings": physical, facility, fiscal, economic, statutory parameters. Some of them (i.e. physical and facility indicators) are mere "signs" of possible states of abandonment-they reflect brute facts-while others try to identify abandonment more substantially as a social fact (i.e. fiscal, economic, statutory). 1 Obviously, these indicators can be used in combination. Let us consider them in detail.1. Physical parameters, for example, the peeling of façade paint, deterioration and collapse of the structures, signs of vandalization, infestations, etc. deriving 1 In this regard, Searle (1995, p. 85) points out: "possession is typically manifested quite differently for real property than for personal property. I can wear my shirt, drive my car, even carry my computer, but when it comes to my house and land, maintenance of my possession requires status indicators". He goes on underlying that: "The French distinction between 'meuble' and 'immeuble' reveals precisely this distinction" (Searle 1995, p. 84; italics in the original). This similarly applies in the Italian language (i.e. "mobili", "immobili").
