Ces alternatives permettent aussi d'envisager des bifurcations du métabolisme urbain fortement consommateur d’eau. Cependant, on voit aussi le rôle que joue l'action citoyenne dans l'émergence d'alternatives environnementales à même de réguler les usages de la ressource. Dans cet article, nous montrons que des stratégies d’adaptation sont mises en œuvre par les acteurs dominants afin de maintenir la trajectoire de croissance de villes particulièrement attractives.

L’analyse mobilise les outils et concepts de l’urban political ecology, afin d’observer les rapports de pouvoir entre les acteurs de la gestion de l’eau, dans un contexte où le système de grandes infrastructures hydrauliques sous-tendant la croissance urbaine est de plus en plus remis en question. S’appuyant sur un terrain qui fait jouer à l’extrême les problématiques socio-écologiques de la pénurie, ce travail de recherche propose de considérer les villes de Phoenix et de Tucson comme des laboratoires de l’adaptation urbaine au changement climatique, pour explorer les différentes modalités d’adaptation à la rareté de la ressource en eau.

As a remark, in Henderson, 2013, Trench 1 ¼ DA Trench 18, Trench 2 ¼ DA Trench 11 and Canal 1 ¼ DA Canal 3.Ĭet article se concentre sur la gestion de la rareté de la ressource en eau dans deux métropoles de l'Ouest aride des États-Unis confrontées à une intensification des sécheresses et à un stress hydrique accru. This does not provide information on the river discharge, but on local hydro-sedimentary dynamics which highlights the importance of studying multiple crosscuts of hydraulic structures to understand the significance and origin of the deposits. The canal is filled with blocky clay indicating reduced to non-existent flow. Canal 1 truncates active intermittent channels from nearby alluvial cones (see US 7, 11, 12, 13) d) Stratigraphic description of Canal 1 in trench 2, downstream of its intersection with intermittent streams. a) Location of the hydraulic structure studied (Canal 1) and trenches 1 and 2 dug perpendicular to its alignment b) View from the east of Trench 1 and description of the environmental dynamics encountered c) Stratigraphic description of Trench 1.

As water systems are structural elements of the spatial and socio-political organization of societies, this approach will provide elements to discuss the relative impact of human and/or environmental factors on landscape change and cultural shifts, and measure the long-term vulnerability and resilience of agricultural communities to regional environmental changes.Įxample of the significance and origin of deposits in hydraulic structures (lower Salt River valley, Phoenix, Arizona e Phoenix Sky Train ® project U:9:28 e Fig.

While they can be applied to different environmental contexts, they will be presented through the example of Hohokam irrigation systems in the semi-arid Phoenix basin, Arizona, where this approach has been applied as a whole. The principle and limits of the methods applied to this research object are presented and discussed in this paper. This socio-environmental signature recorded in the spatial organization, sedimentary fill and profile of hydraulic structures can be reconstructed by means of a systemic cross-disciplinary approach (geoarchaeology, chronology and paleoenvironment). Their temporalities (construction, maintenance, abandonment) represent an image of a social, cultural, economic and political context as well as changing environmental conditions. Water systems lie at the interface between nature and culture and in that perspective are a rich but under-explored research object.
