Abstract
La situation actuelle des ressources en eau et de leurs usages dans le Sud-Est tunisien présente des enjeux qui sont communs à de nombreuses régions du bassin méditerranéen : des ressources limitées et déjà largement exploitées pour répondre à la croissance des besoins, le recours accru aux ressources dites non conventionnelles, une situation de concurrence entre usages sectoriels, une marchandisation croissante des ressources, et des conditions climatiques contraignantes qui viennent renforcer les tensions autour de l'eau. Dans le contexte des mutations en cours, face aux risques de déficits en eau et à la nécessité d'un développement économique et social équilibré, ces caractéristiques, parmi d'autres, font de la Jeffara tunisienne un cas d'étude exemplaire des difficultés que pose la gestion intégrée de l'eau. Celle-ci doit prendre en compte les différentes sources d'approvisionnement ainsi que les différents usages associés, et donc l'identification des territoires pertinents pour cette  gestion, compte tenu des relations amont-aval naturelles et artificielles d'une part, et des cohérences institutionnelles et sociales d'autre part.<br>The current situation of the water resources and their uses in South-Eastern Tunisia presents stakes which are common to many areas of the Mediterranean basin : limited and already largely exploited resources to address the growth of the needs, the increasing use of so-called non conventional resources, a competition between sectoral uses of water, an increasing merchandising of the resources, and constraining climatic conditions which reinforce the tensions around water. In the context of the changes in progress, facing the hazard of water deficits and with the need for a balanced economic and social development, these characteristics, among others, make Tunisian Jeffara be an exemplary case of study of the difficulties raised by the integrated water resources management. This one should take into account various related sources of supply and uses, and thus the identification of the relevant territories for this management, accounting for both natural and man-made upstream-downstream relationships, and institutional and social consistencies.
