The Struggle for Terroir in French Algeria: Land, Wine, and Contested Identity in the French Empire

Pedigo, Nathan Welsz 01 May 2015 (has links)
This dissertation explores the history of the French Algerian wine industry. The product of an ecological disaster in Europe the wine industry in French North Africa became the fourth largest producer of wine in the world by the mid-twentieth century. French Algeria played a leading role in "saving" the French wine industry during the Phylloxera crisis of the late nineteenth century. From 1863, this insect-borne disease had begun to spread in French vineyards. By the late 1870s, it had become a veritable epidemic, killing the vines that produced France's second most important product. French wine production, which had reached an all-time high in 1875, dropped by more than two-thirds before bottoming out in 1887. The devastation of French vineyards required that France import large amounts of wine from North Africa in order to replace the lost harvests. Scholars have recently turned their attention to the constructed relationship of drink, especially wine, to French identity. A tremendous gap exists in the cultural history of French Algeria, particularly where wine and empire are concerned. This dissertation seeks to redress this scholarly imbalance. Viewed as a conduit of "Frenchness" in French Algeria, debates about wine production in the region symbolized a broader intra-French struggle over French Algeria's place within "Greater France." This dissertation argues that the French Algerian wine industry played a significant role in the development of modern French identity.

Biologie van die wingerdfilloksera Phylloxera vitifoliae (Fitch)(Homoptera: Phylloxeridae) in Suid-Afrika

De Klerk, C. A. (Christiaan Andreas) January 1970 (has links)
Thesis (MScConsEcol)--Stellenbosch University, 1970. / AFRIKAANSE OPSOMMING: Verskeie aspekte van die biologie van die wingerdfilloksera is bestudeer. Die ondergrondse lewensiklus is in spesiale teelbakke waargeneem en die ontwikkelingstydperk van elke stadium word afsonderlik aangegee. Dit is bepaal dat die ontwikkeling van n eier tot n volwasse radicicolae-wyfie gemiddeld 22 dae duur en dat die ontwikkeling van n eier tot n alata gemiddeld 30 dae duur. Die leeftyd en tydperk van eierlegging van n volwasse wyfie asook die aantal eiers wat geproduseer word, word aangegee. Verskillende gegewens wat in verband met oorwintering verkry is, word bespreek. Die tyd van voorkoms van die verskillende stadia van die radicicolae-siklus in die natuur, is bepaal. Die aktiewe · stadium duur vanaf September tot Mei, die oorwinterende stadium vanaf April tot Oktober en nimfe kom voor vanaf November tot April. Met die gegewens verkry, is die aantal generasies per jaar teoreties bepaal. Filloksera is tot op n diepte van 1.2 m in die grond gevind. Daar is vasgestel dat verskillende grondtipes n invloed op die fillokserabesmetting het. Die besmetting neem af soos die persentasie fyn plus medium sandinhoud van n grond styg. Opnames het getoon dat 95% van die wingerde met Jacquez as onderstok in die Stellenbosch-area besmet is en dat ongeveer 25% van alle wingerde in die Olifantsrivier-besproeiingsgebied besmet is. Met behulp van sekere vangapparate is alatae vir die eerste keer in Suid-Afrika in die natuur versamel. Die leeftyd en eierproduksie van alatae en verskillende aspekte van die voorkoms van die galicolae-siklus word bespreek. Twee metodes is toegepas om morfologiese rasse van filloksera·te onderskei. Met behulp van een van die metodes kon verskille tussen die populasies van die twee geografies verskillende areas wat ondersoek is, aangetoon word. / ENGLISH ABSTRACT: None

La crise viticole du "Alto Douro" (1907-1915). Entre réalité sociale et discours idéologique dans le cycle "Port-Wine" d'Alves Redol / The wine-growing crisis of Alto Douro (1907-1915) Between social reality and ideological speech In Alves Redol’s Port-Wine cycle

Diouf, Lucien Demba 29 June 2010 (has links)
Notre thèse se propose de démontrer dans quelle mesure et par quels procédés Alves Redol s’inspire de la crise viticole du Alto Douro (1907-1915) sous ses aspects humains, politiques et socio-économiques pour élaborer l’architecture de sa trilogie. Cette problématique permet de découvrir combien la possession et la dépossession de la terre sont incontestablement deux axes fondamentaux qui décident du sort des protagonistes. Ce travail consiste à s’interroger sur les différents mécanismes qui sont au début de cette crise viticole, qui ont engendré un déséquilibre économique et par conséquent, d’importants changements tant au niveau de l’organisation sociale qu’au niveau des rapports sociaux. L’objectif de ce travail est de montrer comment la terre schisteuse du Douro, productrice du vin de Porto, façonne foncièrement l’homme dans sa dépendance fatale de la rigueur inexorable des saisons. Les viticulteurs dans la trilogie redolienne, et par le biais de l’intertextualité, sont aux prises avec une multitude de difficultés dues à plusieurs éléments : facteurs législatifs (signature d’un traité de vente de vin avec et en faveur de l’Angleterre) ; facteurs naturels (sous-production avec le phylloxéra et le mildiou) ; facteurs humains (surproduction et mévente avec la concurrence et surtout avec la contrefaçon du vin de Porto). Dans le sillage des théories marxistes-léninistes et du matérialisme dialectique, nous avons tenté de montrer que, malgré les procédés d’animalisation et de perspectives de privations continuelles des viticulteurs et des sans terre par les détenteurs des moyens de production, la masse rurale unie, réussit à se révolter contre l’exploitant et pour un nouvel ordre social. / Our thesis intends to prove to what extent and by what processes Alves Redol inspired by the Alto Douro wine-growing crisis (1907-1915) in its human, political and socio-economic dimensions to develop the architecture of his trilogy. Posing the problem in this fashion enables us to highlight that land ownership and dispossession are unquestionably two main axes which have an influence on the protagonists’fate. Our work examines the different mechanisms at the root of the wine-growing crisis, which created an economic imbalance, and consequently important changes in social organization as well as social relationships. This work aims at showing how the Upper Douro’s schistose soil, a key element in Porto wine production, also fundamentally fashions man and makes him dependent on the rigour of the cycle of seasons. In Redol’s trilogy, wine-growers, through the intertextuality process, are confronted with many difficulties due to various elements, whether they be legislative (the signing of a wine sales treaty in favour of England), natural (underproduction caused by phylloxera and mildew), or human (overproduction and bad sales due to competition and counterfeiting of Port wine). In keeping with Marxist-Leninist theories and dialectic materialism, we intend to show that, in spite of the dehumanization process and constant deprivation of wine-growers and landless people by those who control means of production, the united rural world succeeded in rebelling against its exploiters to achieve a new social order.

Territorio e vitivinicoltura nell'Oltrepò Pavese: dall'indagine geostorica alle sfide attuali della geoeconomia / Territory, grape growing and wine making in Oltrepò Pavese: From a geographic investigation to the challenges of the modern global economy

MAFFI, LUCIANO 17 February 2009 (has links)
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.
