In 2020, Slovenia recorded a slight increase in the number and total area of functionally depreciated areas (FDAs): 1,132 FDAs were recorded in the total area of 3,695.3 ha. Compared to 2017, their number increased by 51, with a total area of 272.5 ha.

We can notice positive trends towards the revitalization of FDAs, as new activity has taken off on 108 locations, on the 292 FDAs there have been major changes in recent years, where many remediation and renewal processes began, while else ware the physical condition and degradation of the area has deteriorated.

Systematic research on soil pollution shows that soils in Slovenia, with some exceptions, are not heavily polluted. In 42% of top soil samples taken in the period from 1999 to 2019, no exceedances of the limit values of dangerous substances into the soil were detected. In 56% of the samples the limit values of inorganic pollutants were exceeded and in 5% the limit values of organic pollutants. The most polluted areas with inorganic pollutants were Jesenice, Idrija, the Celje Basin and the Upper Mežica Valley.

In the last decade, droughts have been slightly less intense than in the previous decade, and it is worrying that they occur most often during the growing season. Especially in the first trimester, we observe a decrease in the frequency and intensity of hydrological drought. In the period 1961–2020, the year 2003 stands out in terms of drought, which was dry in all quarters of the year. After 2000, the years 2007 and 2011 were more markedly dry.
