“…The effects of the climate change over the last several decades have begun to transform natural and managed hydrological systems. One of the most sensitive and most visible climate change impacts on hydrological systems is the retreat of glaciers (Haeberli et al, 1999;Kargel et al, 2005;Oerlemans, 2005;Shahgedanova et al, 2005;Dong et al, 2013;Xie et al, 2013;Elfarrak et al, 2014;Nistor and Petcu, 2015). Less visible aspects of hydrological processes and water resources are equally affected, however.…”

Evapotranspiration plays an essential role in estimating water balance, runoff and effective precipitation. To determine historical and projected water availability for Europe, we contribute high‐resolution (1 km) estimates of monthly and annual potential evapotranspiration (ET0) and actual evapotranspiration (AET0). In the ET0 calculation, the monthly and annual heat index I and annual α parameter were estimated following the Thornthwaite method, and AET0 was calculated using the Budyko approach. The variables were estimated for a climate normal period that largely precedes an anthropogenic warming signal (1961–1990), and for two CMIP5 multi‐model future projections (2011–2040 and 2041–2070). We project widespread and relatively uniform ET0 increases of around 50–100 mm by the 2020s and 75–125 mm by the 2050s for most of Europe. These values imply important changes that may affect runoff and groundwater recharge. AET0 was identified as important driver of water availability with more regional variability. Spatial mapping of changes relative to the normal baseline imply that all except northern parts of Europe are vulnerable to water deficits, with pronounced decrease expected in southern Europe. We provide high‐resolution maps and data as an important tool for future natural resources management and climate change mitigation planning.

“…In this sense, several research studies using effective tools such as geographic information systems have been developed to study the vulnerability of these wa-ters to pollution, with a view to delineating the most vulnerable areas, assessing pollution risk and creating vulnerability maps that constitute an essential information base facilitating decision-making (Sinan et al, 2003;Rahman, 2008;Ferrak et al, 2014;Arshad et al, 2019;Onwe et al, 2020).…”

In Morocco, groundwater is of major importance in national economic policy, that's why groundwater management programs are periodically installed to prevent their qualitative and quantitative degradation. Our work comes to contribute to this program by studying the inherent vulnerability to pollution of the Skhirate-Temara region (NW Morocco) using the GOD-Foster method. The latter defines the vulnerability of aquifers based on the resistance to pollutant penetration and the mitigation capacity of the underlying layer of the saturated zone while neglecting the lateral migration of pollutants into the saturated zone. The vulnerability map will delineate areas vulnerable to pollution and will serve as a decision-making tool to take the necessary action.

“…However, most of the time the effects on health are mediated; such an example may be the increased contamination of groundwater with various pathogens because of higher frequency and intensity of floods. This results in enteric disease [12], often caused by the spread of pathogens like Campylobacter, Cryptosporidium, norovirus, or vibrio [13].…”

Water resources and environment quality are nowadays under high pressure because of climate change, land use practices, as well as human actions. A comprehensive gridded dataset becomes a necessary instrument to assess the risk level at regional scale, and also for territorial planning, the defining strategies to address future natural and anthropological challenges. In order to obtain a complete database with the most important parameters at spatial scale, this study is constructed as a preparation of layers used for various environmental risks, but mostly with the climate change effect on the water resources from the Grand Est region, France. In addition, geological formations, terrain data, and land cover were harmonized as grid format for the study area. Thus, the temperature and precipitation parameters, related to the 1961–1990 (1990s), 2011–2040 (2020s), and 2041–2070 (2050s), become useful data for evapotranspiration, water availability, and effective precipitation calculations. The geology layer indicates the composition and types of aquifers and it contributes to the potential infiltration map (PIM). The morphology of the terrain contributes to the slope angle and PIM. Through the typology of land cover, the pollution load index (PLI) was estimated. The findings indicate intense aridization and the depletion of the effective precipitation (below 650 mm) during the present and future periods. With respect to these concerns, the surface waters and groundwater resources from the Grand Est region are experiencing the negative effects of climate change on runoff and aquifers recharge respectively. In addition, the high PLI in the industrial and agricultural areas contribute to the possibility of the increasing water resources vulnerability. The affected areas extend mainly in the western, north-central, and north-eastern parts of the region, mainly in the Rhine, Aube, and Marne Valleys. Considered as a precious resource in the region, the water management should follow best practices for vulnerability and risk assessment, and further to delineate the protection areas. As a comprehensive gridded dataset, the calculations and original maps presented in this paper represent a complex product with main environmental parameters processed at spatial scale of 1 km2 in ArcGIS. This product has the purpose to integrate the geospatial data for the Grand Est region of France.
