The identification of changes in drought occurrence has been done at different spatiotemporal scales and using different approaches, with results that may not be fully comparable. The study aims to fill this gap by analysing drought trends in the northwestern region of Italy using a consistent approach.

The direct and indirect influences on multi-scale meteorological and hydrological droughts remain insufficiently understood, particularly in karst basins. Drought assessment is based on various drought indicators, and different time scales can also affect drought evaluation, leading to uncertainty in the results.

Despite extensive research on droughts in Europe, limited studies have addressed the spatial and temporal variability of hydrological droughts across Poland's diverse physiographic regions, particularly concerning the interplay of precipitation, potential evapotranspiration ( PET ), standardised runoff index ( SRI ), and temperature.
