Germany is experiencing a spring drought in 2025. In large parts of Germany, less than 35% of the usual precipitation fell between February and the beginning of April, according to analyses by the German Weather Service. This is particularly noticeable in the soil moisture, as can be clearly seen in the UFZ Drought Monitor. Especially now - at the beginning of the growing season - a lack of water in the soil is particularly critical for arable and grassland areas.
Agriculture is not the only sector affected. Exceeding the water storage capacity in the soil is a prerequisite for natural, extensive groundwater recharge. This happens above all during and after winters with high precipitation. Drought signals reach the groundwater with a time delay because it has a long-term memory. Groundwater levels can only rise to an average level again after years of wet weather and pronounced groundwater recharge.
This process chain shows us how important it is to have a reliable data basis in hydrology and hydrogeology and to be able to use suitable methods to obtain information about our environment. How else can we arrive at quantitative statements on the basis of which we can make decisions on soil and water protection?
With ENOLA, we are working on a cooperative environmental data platform for hydrological and hydrogeological projects of all kinds for all stakeholders.
