“…Growing population in the area (Pima County was just over 1 million in 2018 (Bureau of Reclamation 2019) has increased demand for potable water. The city of Tucson is dependent on allocations from the Colorado River through the Central Arizona Project (CAP) and its own aquifer (Central Arizona Project 2017; Kuhn et al 2017). Outdoor water consumption accounts for 45% of potable water consumption in Tucson and the primary outdoor water usage is for landscaping irrigation.…”

Effective management of cities using ecosystem services from green infrastructure (GI) requires explicit consideration of the linkages between provision of services and ecosystem service demands (i.e., governance priorities). Identi cation of stakeholder knowledge and objectives in GI decision-making contexts with respect to ecosystem services may improve urban planning; yet this information is rarely explicit in local contexts and cases. We address this gap by surveying environmental stakeholders and practitioners to investigate how perceptions of ecosystem services in uence GI practice in Tucson, AZ.Results indicate that the semi-arid environment and urban design led to prioritizations that focus on water sustainability and urban heat mitigation. We found strong agreement in environmental perceptions between different management sectors. We observed matches (as well as mismatches) between the ecosystem service priorities and important environmental issues. Ecosystem services prioritization revealed a unique classi cation of ecosystem services that re ects stakeholder priorities. Our ndings suggest the study of ecosystem services supply and demand can inform local urban management. These ndings from a semi-arid city further suggest that understanding stakeholder knowledge, perceptions, and priorities should be important for cities in other regions where GI is being implemented as an environmental solution to provide ecosystem services.

“…Rainwater harvesting joins other alternative water supplies such as greywater harvesting and reclaimed water which completes conventional water supplies from the CAP and the aquifers (KUHN et al, 2016;SCHNEIER-MADANES et al, 2016). The overall goal is to decrease the dependence on the aquifers and the CAP to ensure that the answer to the future demand of a city whose population is growing can be made secure.…”

Water Conservation in Desert Cities: From the Socioecological Fix to Gestures of Endurance

Urban water provision is the archetypal case for the recent wave of urban political ecology, using the concept of “fix” to illustrate belief in technical forms to solve socioecological problems like uneven water distribution and environmental degradation. On the one hand, this paper shows that the risks of water shortages in Arizona, USA are a technical concern. Professionals are dedicated to the promotion of water conservation to “fix” a dysfunctional hydro-social cycle. Yet, environmental organizations raise a critical approach to this “hydrocracy”. They defend local water supplies, river regeneration, and reuse as promoting a low water-use “desert lifestyle”. Building on the intellectual history of “fixes”, we apply Giorgio Agamben’s concept of “gesture”, signaling how, in places of deep water scarcity, water conservation policies remain within notions of growth, such that pauses in water availability leave open future promises of resource abundance so the moment of scarcity can be endured.

“…La durabilité d'un cycle hydrosocial reposant largement sur l'eau du CAP est donc de plus en plus remise en question. Face à ces risques, des sources d'approvisionnement en eau alternatives sont de plus en plus mises en valeur à Tucson (Kuhn et al, 2016 ;Schneier-Madanes et al, 2016), et notamment l'eau de pluie.…”

“…Plus récemment, les politiques publiques mises en place par la Ville se sont montrées particulièrement favorables à la collecte des eaux de pluie et sont souvent citées comme modèle à l'échelle régionale, voire à l'échelle des États-Unis (Meehan et Moore, 2014). En effet, à l'échelle de la ville, l'utilisation des eaux de pluie chez les habitants, mais aussi pour l'irrigation des espaces publics, aurait la capacité de réduire de 20 % la pression urbaine sur les nappes phréatiques (Kuhn et al, 2016).…”
