Managing groundwater resources using a national reference database: the French ADES concept

Groundwater is an integral part of the water cycle and an essential human resource. Humans must protect this ever-changing heritage and preserve it in a sustainable way by understanding the physical and chemical properties of aquifers and monitoring their quantity and quality. Numerous studies have collected immense volumes of data that are difficult to access and not always comparable or of adequate quality. A pioneering national-scale database, ADES, was created in 1999 to store and make available quality data on French groundwater. This tool is freely accessible for/to water managers, scientists and the public. The data management system used in the database satisfies two important objectives: it is interoperable and based on a recognised groundwater reference system and provides high quality data to a large public. Data from different producers require normalisation and standardisation of system requirements to allow data integration and exchange. The database designers set up shared data models, and based the system on communal repositories of water points and hydrogeological entities. Nearly 102 million groundwater quality records and over 17 million water-level records are currently available, describing almost 61,800 stations. ADES makes it possible to visualise in “real-time" water level data for approximately 1500 stations equipped with GPRS (General Packet Radio Service) technology. ADES also provides, on a public website and via web services, public quantitative and qualitative data. ADES is an essential tool for developing groundwater services based on the FAIR guiding principles: Findable, Accessible, Interoperable and Reusable data (Wilkinson et al. in SD 3:160018, 2016) Article highlights A unique database for storing and disseminating reliable, comprehensive, and up-to-date groundwater data to a large public. An interoperable system based on a common reference system to ensure data reliability. An interoperable system based on a common reference system to ensure data reliability.

“…There is also the risk of “regulatory capture” which is a situation where the relationship between the regulator and the regulated is too close and threatens the environmental effectiveness and the fairness of negotiated outcomes (Lopez‐Gunn & Cortina, 2006). In France, the setting of volumetric extraction caps is an outcome of a participative process, which has so far resulted in generous user allocations at the expense of meeting environmental requirements (Arnaud, 2020; Rouillard & Rinaudo, 2020).…”

Groundwater forms the invisible, subsurface part of the hydrological cycle, playing a vital role for maintaining base flows of rivers during the dry seasons. It is also a vital source of water for modern economies, accounting for 25% of total water extraction worldwide and a quarter of the irrigation water used to grow the world's food (Aquastat, 2016). Yet, aquifers are being over-exploited at an alarming rate in many regions around the world-a situation that is expected to worsen under climate change as recharge rates will be increasingly affected (Famiglietti, 2014;Taylor et al., 2013). Groundwater depletion contributes to the decisions by water managers to "close" access to water resources in aquifers and river basins (Molle et al., 2010). As societal and environmental needs cannot be met for at least part of the year, water managers must deal with complex trade-offs between economic interests, livelihoods, and environmental priorities.To tackle overexploitation, groundwater management is progressively shifting from an open-access regime of water resource extraction to one of regulated access all over the world (Giordano et al., 2009;Shah, 2009). Regulated access typically relies on setting a sustainable flow rate or volumetric cap on total water extraction, and reducing and maintaining extractions at or below that cap (Rinaudo et al., 2020). It can also rely on a pigouvian tax or restrictions imposed when sustainability limits are reached (for example, groundwater threshold levels). The core issue when closing access to water resources becomes how to best allocate limited water supplies between competing users, and between users and the environment. It involves setting up processes and mechanisms which enable social actors to share water according to a recognized set of values and priorities.Much academic debate has focused on the question of who should control or supervise allocation decision-making, with no conclusive outcome as to whether state or community approaches are preferable (Bruns et al., 2005;Rinaudo et al., 2019). On the one hand, state approaches appear more accountable, but they have usually failed to effectively reduce groundwater use to sustainable levels (Molle & Closas, 2020b). On the other hand, community approaches appear more legitimate, at least to the regulated. They have been most effective where the community had a social basis for collective action, for example a common

“…Methodologies for assessing the SEL vary greatly, ranging from simple statistical analysis to sophisticated integrated surface-groundwater models. Reporting on an analysis of a sample of those studies, Arnaud (2020) warns that the setting of SELs in France is not always scientifically robust and that SELs have sometimes been overestimated due to various reasons, from insufficient knowledge to political pressure from water users. However, he shows that SELs have often been 10 to 20% below current water use levels, and up to 50% in some cases, posing major challenges to authorities charged with reducing allocations to water users.…”

The book brings together a range of leading scholars and practitioners to compile an international account of water allocation policies supporting a transition to sustainable water use in regions where agriculture is the dominant water use. In Section 1, the collection canvasses five key crosscutting issues shaping the challenge of sustainable water allocation policy, such as legal and economic perspectives, the role of politics, the contributions of engineering and technology, the setting of environmental flows, and the importance of indigenous rights. Section 2 presents 16 national, state and transboundary case studies of water allocation policy, covering cases from Europe, the Americas, Central Asia, the Middle East and the Pacific region. These case studies highlight novel and innovative elements of water allocation regimes, which respond to the cross-cutting issues addressed in Section 1, as well as local challenges and social and environmental imperatives. The book provides a comprehensive account of water allocation in a range of international settings and provides a reference point for practitioners and scholars worldwide wishing to draw on the latest advances on how to design and implement sustainable water allocation systems.
