Soil drought has a key impact on plant development and consequently on various industries (forestry, agriculture, …) . Indicators of the number of drought days and the duration of drought periods in individual years show an increase especially after 1990. Similarly, the analysis of the impact of the climate change up to 2100 shows that soil water deficits will increase in the future. The number and the duration of the droughts will increase.

Water protection areas (WPA) comprise approximately 17% of the territory of Slovenia. Going by land use in these areas, forest (61.1%) prevails, followed by grassland (13.6%) and arable fields (10.9%). Ecologically farmed land represents only 1.7% of total WPAs and 6.04% of agricultural land on WPAs, with grassland representing the largest share at 79.6%.
