As drinking water supply systems worldwide face increasing challenges, there is concern of future drinking water shortage. This paper proposes an innovative participatory modelling framework to fill the lack of tools to assess future demand-supply imbalances under global changes in large interdependent drinking water supply systems for which collec...
Many cities are developing infiltration infrastructures aimed at restoring natural hydrological processes. Among those, Nature-Based Solutions (NBS) can generate co-benefits, which contribute to cities’ adaptation to climate change. However, choosing optimal locations for infiltration infrastructures within limited available urban space is a comple...
La présente communication se focalise sur les eaux souterraines et sur la sécheresse hydrogéologique. Les dernières années 2017-2019-2022 se sont caractérisées par des situations de sécheresses prolongées touchant des zones traditionnellement moins impactées. Face à cette problématique, le système d’alerte précoce MétéEAU Nappes a été mis en place...
But du travail :
Ces dernières années se sont caractérisées par des situations de sécheresses prolongées et répétées, dont le dernier épisode en 2022 a conduit à la mise en œuvre de nombreux arrêtés préfectoraux dits « arrêtés sécheresse » entraînant des mesures de restriction des consommations d’eau sur la quasi-totalité du territoire français, vo...
Analysing practices, social representations and behaviours of socio-hydro systems' actors. Abstract: This working paper presents and discusses the approaches and methods used by the PRECOS Team of the G-Eau research unit to analyse practices, social representations and behaviours of socio-hydro systems' actors. Four groups of methods are presented:...

Highlights
• We propose a method to identify cost-effective actions to reduce groundwater nitrate concentration.
• Actions deemed promising and achievable by stakeholders can prove ineffective.
• The method raises awareness on hydrosystem inertia and helps envision effect...
Large deep confined aquifer systems play a crucial role for water and food security and the economic development of rural areas. However, there are few cases, worldwide, of integrated management and governance of such groundwater resources. This report first investigates factors that hamper stakeholders' involvement in groundwater management, in pa...
A global meta-analysis consisting of almost three decades of groundwater quality valuation studies is presented. New in this study is the focus on the uncertainties surrounding different groundwater quality levels and the control included for groundwater contaminants originating from agriculture and other sources. Separate meta-regression models ar...
This paper presents a methodology to project irrigation and domestic water demands on a regional to global scale, in terms of both quantity and economic value. Projections are distributed at the water basin scale. Irrigation water demand is projected under climate change. It is simply computed as the difference between crop potential evapotranspira...
Global changes are expected to exacerbate water scarcity issues in the Mediterranean region in the next decades. In this work, we investigate the impacts of reservoirs operation rules based on an economic criterion. We examine whether can they help reduce the costs of water scarcity, and whether they become more relevant under future climatic and s...
Les changements globaux, socio-économiques et climatiques, vont très probablement accroître les tensions sur les ressources en eau dans la région méditerranéenne dans les prochaines décennies. Dans un contexte de contraintes en eau inégalement distribuées géographiquement, des interactions entre bassins pourraient se développer. Par exemple, les ac...
The present work focuses on the demand side of future water scarcity assessment, and more precisely on domestic water demand. It proposes a quantitative projection of domestic water demand, combined with an original estimation of the economic benefit of water at large scale. The general method consists of building economic demand functions taking i...
L'etude de cas presentee ici s'interesse a la tarification de l'eau potable domestique, dans une zone d'etude couvrant 300 communes du sud de la France. Elle commence par decrire les tarifications existantes, revelant que la tarification n'est pas encore utilisee comme un outil d'incitation aux economies d'eau. Elle presente ensuite les resultats d...
The case study conducted in this paper looks at residential water pricing from three different points of view. It first describes existing urban water-pricing practices in Southern France, emphasizing that pricing is not yet being used as a tool for providing economic incentives to save water. It then looks at the observed impact of pricing on wate...
Cet article présente les facteurs explicatifs de la consommation en eau potable à travers une étude de cas particulier située dans la vallée de l'Hérault en France.
The case study conducted in this paper looks at urban water pricing, in an area covering 300 municipalities of Southern France. It first describes existing urban water pricing, pointing up that pricing is not yet used as a tool providing incentives for households to save water. It then presents the results of a modelling exercise which illustrates...
