La viticoltura nella regione biogeografia mediterranea è una pratica rilevante nella tradizione culturale europea, attraverso la coltivazione dell’uva per la produzione di vino. Lo straordinario territorio mostra comunque le sue criticità per il mantenimento della stabilità e delle condizioni ottimali del terreno, portando l'antica tradizione vinicola alle generazioni successive con le nuove sfide di gestione sostenibile del territorio. L’interesse nelle rimarcabili pendenze dei territori collinari è stato argomento di studio di questa tesi, mappando i punti di interesse dovuti al ruscellamento delle acque piovane sui vigneti in forte pendenza sulle colline di Brognoligo-Costalunga, un territorio agricolo tradizionale all’interno del Consorzio di Tutela del Soave (regione Veneto, Italia). Il lavoro è basato sul telerilevamento e sull’applicazione dell’indice geomorfometrico RPII, basato sulla topografia di dettaglio superficiale, in grado di fornire informazioni affidabili riguardo il territorio. La regione di Soave ha una economia fortemente dipendente dalla produzione di uva attraverso la viticultura su terrazzamenti collinari. Il bellissimo territorio collinare presenta tuttavia delle problematiche nella gestione del sistema di drenaggio delle acque piovane e le condizioni meteorologiche mettono in evidenza questo problema. I problemi associati all’ambiente come il ruscellamento delle acque piovane saranno discussi come un problema ambientale che se non contenuto nel tempo, per effetto domino, può interessare tutto l'ambiente. L’indagine evidenzia cosa dovrebbe essere evitato per meglio gestire il territorio, fornendo alcuni spunti per mitigare il degrado del terreno e i principali fattori che impattano sulla pendenza collinare. Questa indagine presenta inoltre uno spettro di strumenti disponibili che potrebbero creare dati essenziali per la ricerca, approfondendo così la conoscenza delle problematiche del paesaggio. Le informazioni presentate in questo lavoro, intendono inoltre sensibilizzare sulle conseguenze relative all’alterazione paesaggistica e sull’importanza dei rilievi e dei piani di utilizzo del territorio. Questa indagine presenta inoltre uno spettro di strumenti disponibili che potrebbero creare dati essenziali per la ricerca, approfondendo così la conoscenza delle problematiche del paesaggio. Le caratteristiche dei terrazzamenti collinari devono essere preservate in quanto ci sono ancora risorse disponibili che possono essere applicate per mantenerli in modo ottimale. La salvaguardia del territorio che fu costruito da molte generazioni con un’agricoltura collinare sostenibile, è diventato un patrimonio che dovrebbe avere una pratica di gestione sostenibile. Pertanto, l’implementazione del concetto di paesaggio nel piano di gestione del territorio con l'estensione della rete di drenaggio delle acque e l’indagine annuale sull’area, dovrebbero essere cruciali per mitigare gli impatti ambientali. Infine, la tecnologia di telerilevamento è stata presentata come un efficiente strumento per identificare con precisione le criticità paesaggistiche diventando il metodo scientifico ottimale per aiutare il mantenimento dei terrazzamenti agricoli. Le sue elevate prestazioni tecnologiche forniscono informazioni accurate atte a preservare il patrimonio paesaggistico. L’ideale è che le future generazioni portino avanti le tradizioni di conservazione del territorio combinate con l’eccellente produzione di vino, coinvolgendo l’impegno politico, sociale e ambientale, creando nuove strategie per evitare il degrado territoriale e adottare soluzioni per le sfide future. Gli antichi metodi sono tuttora adeguati e dovrebbero essere seguiti in quanto sono stati un ottimo esempio della tradizione agricola mediterranea.

Abstract
The vineyard's agricultural practice on in the Mediterranean biogeographic region is relevant for the European cultural tradition with the cultivation of grapes for wine production. The landscape is extraordinary, but it also has its challenges to maintain its stability for the optimal terrain condition that carries on the ancient tradition heritage vineyards to the next generation with the challenges of managing the landscape sustainably. The interest in the remarkable hillslope landscape has been the study topic of this thesis to map overland flow hotspots in steep slope vineyards of Brognoligo-Costalunga, a traditional agricultural landscape within the Soave wine consortium (Veneto region, Italy). The work is based on remote sensing and on the use of the geomorphometric index Relative Path Impact Index (RPII), to provide stakeholders and households with reliable information about their landscape. The region of Soave has a significant economy that depends on the agricultural practice of grape production on the hillslope terraces. The landscape presents a beautiful view, but in some areas the not optimal management that surrounds the hills slope including the drainage system in addition to climate condition puts in evidence the landscape criticalities.
