Chapter The graphic sign for historical narration of architecture. The fortifications of the Liri Valley

The 43rd UID conference, held in Genova, takes up the theme of ‘Dialogues’ as practice and debate on many fundamental topics in our social life, especially in these complex and not yet resolved times. The city of Genova offers the opportunity to ponder on the value of comparison and on the possibilities for the community, naturally focused on the aspects that concern us, as professors, researchers, disseminators of knowledge, or on all the possibile meanings of the discipline of representation and its dialogue with ‘others’, which we have broadly catalogued in three macro areas: History, Semiotics, Science / Technology. Therefore, “dialogue” as a profitable exchange based on a common language, without which it is impossible to comprehend and understand one another; and the graphic sign that connotes the conference is the precise transcription of this concept: the title ‘translated’ into signs, derived from the visual alphabet designed for the visual identity of the UID since 2017. There are many topics which refer to three macro sessions: - Witnessing (signs and history) - Communicating (signs and semiotics) - Experimenting (signs and sciences) Thanks to the different points of view, an exceptional resource of our disciplinary area, we want to try to outline the prevailing theoretical-operational synergies, the collaborative lines of an instrumental nature, the recent updates of the repertoires of images that attest and nourish the relations among representation, history, semiotics, sciences

La “rappresentazione informativa” per l’analisi della vulnerabilità del paesaggio antropico. Due ambiti territoriali a confronto: il centro storico di S. Elia Fiume Rapido (FR) e il bacino minerario di Coreno Ausonio.

The main riscks of the landscape are the overexploitation of the soil and a high physical vulnerability of our country determined by considerable seismic and volcanic activities, and by the peculiar geomorphological and hydrogeological pattern. This risk needs to be mitigated through a careful analysis of the criticity levels in the different geographical areas and by developing strategies based on requirements and operational guidance. In this paper two different procedures for vulnerability analysis are described, designed for completely different landscape areas. The first case concerns the historical center of Sant’Elia Fiumerapido, in the province of Frosinone, with the objective of analysing the town and its exposure to natural factors of degradation. The second case is the basin of Coreno Ausonio, in the province of Latina, deeply marked by intense mining activities. These two cases constitute examples where the "Informative Representation" allows an immediate reading of the involved components with the aim, in the first case to preserve the evidence of the past, in the second case to protect the environment from uncontrolled human activities.La concomitanza di fattori come l’eccessivo sfruttamento del suolo da parte dell’uomo e l’elevata vulnerabilità fisica del territorio, determinata dalla notevole attività sismica e vulcanica, e dalla particolare conformazione geomorfologica ed idrogeologica, produce un rischio paesaggistico particolarmente elevato che deve essere necessariamente mitigato attraverso un’attenta analisi dei livelli di criticità presenti nei diversi ambiti territoriali e mediante la formulazione di strategie di intervento basate su prescrizioni e indicazioni operative. I sistemi informativi rappresentano un valido supporto poiché consentono di gestire e visualizzare sinteticamente dati molto eterogenei. In questo contributo si illustrano due diverse procedure di analisi della vulnerabilità, progettate per ambiti paesaggistici completamente differenti. Il primo caso riguarda il centro storico di S. Elia Fiume Rapido, in provincia di Frosinone, ed ha come oggetto l’analisi dell’edificato storico e la sua esposizione ai fattori naturali di degrado. Il secondo caso tratta del bacino di Coreno Ausonio, in provincia di Latina, profondamente segnato da un’intensa attività di estrazione mineraria. Questi due casi configurano esempi in cui la “Rappresentazione Informativa” rende facile ed immediata la lettura delle componenti in gioco con l’obiettivo, nel primo caso, di preservare le testimonianze del passato e, nel secondo caso, di salvaguardare l’ambiente da attività antropiche incontrollate
