Cet indicateur vous permet de visualiser les déficits et excédents en précipitations, pour la France métropolitaine, pour chaque année. Pour cela, une "normale" de précipitations est établie, sur la base des données 1997-2020, et vous pouvez comparer une année individuelle sur la base de cette normale.
Sécheresses à venir: que nous disent les données climatiques? Qu’est-ce qui va changer dans notre quotidien? À quel point allons-nous manquer d’eau sur la France? Vous découvrirez ici des pépites pour investiguer sous un angle original et concrêt ces sujets.
The EDO pages contain drought-relevant information such as maps of indicators derived from different data sources (e.g., precipitation measurements, satellite measurements, modelled soil moisture content). Different tools, like Compare Layers, allow for displaying and analysing the information and drought reports give an overview of the situation in case of imminent droughts.
À partir de 2050, les sécheresses « exceptionnelles » devraient se produire désormais une année sur deux — au lieu de une année sur trente. Il y aura de moins en moins d'eau tout au long du XXIème siècle et certains territoires sont plus vulnérables que d'autres.

In recent years, droughts have had substantial impacts on nearly all regions of the EU, affecting several critical systems such as agriculture, water supply, energy, river transport, and ecosystems. These impacts are projected to further increase due to climate change. While some of the drivers of drought risk are well known for some systems and regions, drought risks and impacts remain hard to assess and quantify. The European Drought Risk Atlas is a step towards impact-based drought assessment and can support the development and implementation of drought management and adaptation policies and actions. It characterises how drought hazard, exposure and vulnerability interact and affect different but interconnected systems: agriculture, public water supply, energy, riverine transport, freshwater and terrestrial ecosystems. The Atlas presents both a conceptual and quantitative approach to drought risk for these systems. The conceptual drought risk models (impact chains) are the result of a review of the literat
Flash drought, characterized by unusually rapid drying, can have substantial impact on many socioeconomic sectors, particularly agriculture. However, potential changes to flash drought risk in a warming climate remain unknown. In this study, projected changes in flash drought frequency and cropland risk from flash drought are quantified using global climate model simulations. We find that flash drought occurrence is expected to increase globally among all scenarios, with the sharpest increases seen in scenarios with higher radiative forcing and greater fossil fuel usage. Flash drought risk over cropland is expected to increase globally, with the largest increases projected across North America (change in annual risk from 32% in 2015 to 49% in 2100) and Europe (32% to 53%) in the most extreme emissions scenario. Following low-end and medium scenarios compared to high-end scenarios indicates a notable reduction in annual flash drought risk over cropland. Flash droughts are projected to become more frequent unde
