Oasis explosion and cycles conflicts: territorial transformations of Djerid y Nefzaoua oasis (South Tunisia).

La investigación plantea un análisis de los conflictos de los ciclos del agua en los asentamientos-oasis del Djerid y Nefzaoua, desde la escala del tiempo geológico que dio nacimiento a las fuentes de las aguas artesianas y a la génesis de los oasis tradicionales, hasta los ciclos especulativos de los últimos 70 años explotando nuevos recursos y transformando radicalmente el modelo metabólico del territorio. Si el oasis tradicional permite la ordenanza de un ciclo autosuficiente que limita su capacidad productiva y impone un modelo de asentamiento articulado con el palmeral, el oasis moderno transfigura este equilibro con la explotación de las aguas profundas. Asistimos a la explosión del oasis. El palmeral se desune del asentamiento, se transforma el modelo productivo tradicional integrado en un modelo de monocultivo del Phœnix dactylifera, la palmera productora de dátil, producto territorial muy solicitado en el mercado internacional. Con su dependencia a las aguas de los acuíferos profundos y el conflicto de los ciclos por la contaminación del freático, el oasis entra en una fase de obsolescencia programada, su futuro dependerá de estrategias territoriales que deberían integrar la complejidad de su metabolismo.The investigation drives an analysis of water cycles conflicts concerning the oasis-settlements within the Djerid and Nefzaoua regions. From the large geological timescale originating the artesian water sources leading to the genesis of the traditional oasis, till the high productive cycles of the last 70 years exploiting new water resources and radically transforming the metabolic model of the territory. If the traditional oasis does permit a self-sufficient organization, limiting its production capacity, imposing a model of settlement braced with the palm groves, with the development of deep water-wells, the modern oasis transfigures the cycles constancy. We’re watching the traditional oasis exploding. The palm grove is detached from the settlement, the constituted traditional production model is being turned to a monoculture of the Phœnix dactylifera, the palm tree producing dates, highly demanded in the international market. By its dependence on waters extracted from deep aquifers generating cycles conflicts with the groundwater, the oasis is entering into an era of a planned obsolescence, its future will rely on territorial strategies that shall integrated the complexity of its metabolism

The millet route: understanding a cultural landscape: reactivation strategies for the cultural landscape of Dogon country, Mali

The present study proposes to demonstrate the following hypothesis: there are unique tools, such as Cultural routes and Local Development Planning, which can be used to reactivate a region and that allow both local and touristic activities to coexist without endangering local identity and heritage. The study of these societies, their connection with their own heritage, and their adaptation to the landscape can provide an essential perspective that may help redefine the way we interact with our surroundings. The main goal of this investigation is to come closer to a better understanding of Landscape, Tangible and Intangible Heritage, essential principals and values of Moptis Region in Dogon Country. Fundamentally, to achieve a criteria matrix that supports the articulation of any proposal to the place. We proposed as an instrument of territorial management and organisation, a cultural route with the name Millet Route, and intendeds minimal interference to achieve maximum benefit.Peer Reviewe

Oasis global: análisis multiescalar del Djerid y Nefzaoua (Túnez)

La investigación propone revelar el carácter global de territorios que parecen prima facie totalmente aislados del mapa mundial. Se pretende enseñar a través de una aproximación multiescalar el fuerte enlazamiento que los territorios del Djerid y Nefzaoua siempre han tenido con el mundo. Según una rejilla analítica en la que se consideran tres escalas del tiempo, a saber, el oasis milenario, centenario y decenal, se incorporan las aportaciones de distintas disciplinas —la arqueología, la geografía, la historia, la literatura, la geología, la hidrología y las ciencias sociales— con el propósito de construir un retrato panorámico. Se intentan enfocar las múltiples relaciones del territorio con el mundo, desde la escala del tiempo geológico que dio nacimiento a las fuentes de aguas artesianas, hasta los ciclos especulativos de las ultimas décadas que causaron la explosión del oasis-asentamiento bajo el gran impulso de la exportación internacional del dátil y el desarrollo del turismo.The investigation is proposing to reveal the global features of territories that at first look could be contemplated as totally isolated from the world map. Through a multiscale approach, the aim is to express the strong connections of Djerid and Nefzaoua territories always had with the world. An analytic grid contemplating three timescales, expressly the millenary, the centenary and the decadal oasis, is enabling an original approach. Toward the construction of a panoramic picture of these territories, contributions of different disciplines are combined, including archaeology, geography, history, literature, geology, hydrology and social sciences. The focus is placed on the multiples relations of the territory with the world from the large geological timescale originating the natural water sources which gave rise of traditional oasis, until the recent productive cycles causing the explosion of the oasis-settlement driven by the impulse of date fruit international export and the touristic industry development

Workshop Tunisie

Mahdia, ville millénaire tunisienne à l’âme marine, s’interroge sur le devenir de sa pierre. Son développement urbain côtoie aujourd’hui un nouvel horizon : la ligne de crête d’un ancien cordon littoral où se situent ses carrières. Exploitées, appropriées comme jardin nourricier et également délaissées, celles-ci s’intègrent au devenir de la ville. À peine visible de l’espace urbain, ces carrières ne sont pas des lieux communs. Elles font partie de son histoire. Le défi actuel est qu’elles contribuent aux desseins de cette ville, à son renouveau. Fruit d’une expérience internationale originale qui réunit étudiants, professeurs et experts en architecture de paysage, en architecture, en urbanisme et en études touristiques, ce livre raconte le travail d’expérimentation sur la réhabilitation paysagère des carrières de Mahdia. Misant sur l’apport créatif d’un arrimage culturel entre le Maghreb, le Moyen-Orient, l’Europe et l’Amérique du Nord, le workshop ravive les natures bien singulières des carrières et de leurs contextes. Et surtout, il expose un ensemble d’intentions en vue de leur mise en valeur et de leur développement. Véritable legs pour les citoyens de cette ville méditerranéenne, l’invention paysagère des carrières de Mahdia livre des solutions d’aménagement inédites en quête d’un lendemain
