The frequency of agricultural drought in Slovenia has been increasing in recent decades. In the last twenty years, we have recorded 6 droughts that affected Slovenia at the scale of a natural disaster. Drought is occurring with increasing intensity and in areas and seasons where there have been no problems in the past. An additional risk for agricultural drought are rapidly developing droughts in summer ("flash droughts"), which occur especially during heat waves. Projections show that trend of increasing frequency and intensity of agricultural drought will continue in the future.pp


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.


For the period 2002–2005, an improvement in the chemical and saprobiological quality of rivers was observed.

Due to changes in legislation, this indicator was replaced in 2006 by the indicator [VD12] Chemical and ecological status of surface Waters.


In 2014, 21 out of 22 sections of surface waters met water quality limit values set for assessing the capability of water to support freshwater fish life.

Inapropriate water quality was detected in the cyprinid section of the Mura River between the road bridge in Petanjci and its confluence with the Ščavnica tributary (Mura Mota measurement site) due to excessive concentrations of ammonia, measured on 8 July 2014. The limit value for ammonia in cyprinid waters is 0.025 mg NH3/l, while the measured concentration was 0.043 mg NH3/l.
