Short summary
Severe droughts have increasingly impacted water supply, farming, and forestry in Sweden. This study examines how meteorological, agricultural, and hydrological droughts differ and how they have changed over time and across regions. The results indicate drier conditions in central and south-eastern Sweden, while northern regions show a tendency toward wetter conditions. These findings can inform climate services and support decision-making for drought preparedness and climate adaptation.
