La ricerca analizza l’evoluzione della vitivinicoltura nell’Oltrepò Pavese quale elemento caratterizzante il paesaggio di questo territorio. Tale settore produttivo risulta essere una delle principali attività svolte nell’area in esame e ne caratterizza l’economia, il paesaggio collinare, le tradizioni e le forme identitarie, specialmente nellla zona centro-orientale, ossia nei territori che gravitano sui centri urbani di Casteggio, Broni e Stradella. Il lavoro si propone di approfondire anzitutto la valorizzazione della tipicità e del locale, riassunti e rappresentati nel termine terroir, che indica l’insieme degli elementi geomorfologici, climatici, antropici e culturali che rendono unico un prodotto (in questo caso il vino), mettendo così il locale al centro di un’analisi che si può estendere poi a riflessioni di ordine generale. L’indagine geografica ha studiato gli aspetti ambientali e quelli antropici, nonché le loro relazioni. Si è fatto riferimento ai fattori geologici, pedologici e climatici, che altresì sono gli elementi imprescindibili degli studi di «zonazione» che si occupano proprio dell’interazione tra viticoltura e ambiente. L’indagine geostorica-territoriale si è rivolta soprattutto ai seguenti temi: il paesaggio vitivinicolo; i tipi di vitigni impiantati e i relativi sistemi di coltivazione; le produzioni e la commercializzazione del prodotto; la rappresentazione delle proprietà e del territorio attraverso i catasti. Inoltre si approfondiscono i temi geoeconomici sia a scala globale sia a scala locale, grazie alla rielaborazione delle informazioni relative al settore produttivo. Il contesto locale pertanto è confrontato con quello regionale, nazionale e globale, al fine di comprenderne i legami, soprattutto in relazione alle attuali sfide geoeconomiche. / In this thesis we analyse the evolution of grape growing and wine making as two of the elements which have contributed to the shaping of the landscape in the Oltrepò Pavese and represent two of the main economic activities of this geographic area, with is often identified with them – particularly in the mid-western part, i.e., the areas around the towns of Casteggio, Broni and Stradella. My main goal is to investigate the ways in which the values of locality and typicity – represented by the term terroir – are promoted. “Terroir” stands for, and comprises, a number of elements such as geo-morphological and climatic features, as well as human and cultural factors, all of which contribute to the uniqueness of a product like wine. My research thus starts from, and gives prominence to, the local level, in order to formulate a set of observations from which more general conclusions may then be drawn. The geographical investigation focusses on the environmental and human factors as well as their interrelationships. In its course, we refer to factors such as geology, pedology and climate, the crucial elements of all studies of «zoning», which describe precisely the complex interaction between grape growing and the environment. The geo-historical analysis concentrates especially on thematic areas such as the landscape; the varieties of grape that are planted and the respective growing techniques; the production and marketing of the produce; the ways in which property boundaries and the territory have been represented in land registries. The geo-economic factors, at both the local and global levels, are investigated through the analysis of the data from the production sector. The local context is thus compared to the regional, national and global ones in order to better understand the nature of their interactions and provide useful insights in relation to the challenges posed by the current geo-economic scenarios.

Adopté par l’article 2 de la loi n°2016-1087 de reconquête de la biodiversité, de la nature et des paysages du 8 aout 2016, le principe de solidarité écologique appelle « à prendre en compte, dans toute prise de décision publique ayant une incidence notable sur l’environnement des territoires concernés, les interactions des écosystèmes, des êtres vivants et des milieux naturels ou aménagés ». Ce principe général du droit de l’environnement inscrit à l’article L110-1 du code de l’environnement est destiné à conserver les interactions écosystémiques et les processus écologiques ainsi qu’à améliorer la gestion environnementale des territoires. La dualité de son objet en fait un principe d’une grande richesse, qui devrait concerner de nombreuses décisions. Divers fondements supranationaux, au sein de la jurisprudence et dans les textes internationaux et européens peuvent ainsi lui être attribués. Dans un contexte d’interdépendance écologique, l’évolution de la dimension internationale et européenne du principe reste essentielle pour juger de ses effets au regard de la conservation de la biodiversité. Au niveau du droit interne, son ancrage au cœur de l’équilibre de l’environnement lui apporte un rayonnement particulier. Il conforte le droit à un environnement équilibré et prolonge les principes constitutionnels de prévention et de développement durable. Face à la crise d’extinction mondiale de la biodiversité menaçant notre survie, le principe de solidarité écologique se présente comme cette ultime chance de la conserver. Deux grands ensembles de dispositifs permettent de mesurer la dynamique du principe de solidarité écologique : la trame verte et bleue et la gestion intégrée de la mer et du littoral. Ils constituent une base pour concevoir la solidarité écologique et représentent ainsi le commencement d’un droit nouveau. Le principe de solidarité écologique appelle à les renforcer et, de manière plus générale, à faire évoluer l’ensemble des décisions concernées par le principe. / Adopted by article 2 from act nr 2016-1087 concerning the reconquest of biodiversity, nature and landscape of August 8th 2016, the principle of ecological solidarity calls “for taking into consideration the interactions of ecosystems, living creatures and natural or developed environments in all public decisions having a notable impact on the environment of the territories concerned”.This general principle of environmental law inscribed in article L110 1 of the environmental code is designed to preserve the interactions of ecosystems and ecological processes as well as to improve the environmental management of the territories. The duality of its objective renders it a highly valuable principle which should be applied to numerous decisions. Various supranational foundations, within jurisprudence and in international and European laws, can thus be assigned to it. In the context of ecological interdependence the evolution of the international and European dimension of the principle remains essential in order to see the benefits concerning the safeguarding of biodiversity. It is greatly enhanced, as regards internal law, by the fact that it is at the very center of the environment's equilibrium. It justifies the right to a balanced environment and extends the constitutional principles of prevention and sustainable development. Confronted with the crisis of world-wide biodiversity extinction that threatens our survival, the principle of ecological solidarity emerges as the last chance to preserve it. Two major groups of systems allow us to measure the dynamics of the principle of ecological solidarity: the green and the blue line belt network and the Ocean and coastline Governance Framework. They constitute a basis on which to develop ecological solidarity and represent the beginnings of new legislation. The principle of ecological solidarity requires them to be reinforced and more generally to advance all decisions concerned by the principle.
