Precipitation is highly variable in space and time, even more than temperature, and extreme precipitation events (storms with torrential rain, hail) and drought are of particular concern. In the last two decades, Slovenia  has been observing extreme droughts and abundant precipitation resulting in floods. Drought and floods can occur even within the same year. The maximum snow cover depth and the depth of fresh snow decreased in the period 1950–2022.

In 2023, around 182 million pieces of plastic carrier bags were placed on the Slovenian market, of which 99% were those with a wall thickness of less than 50 microns (light plastic carrier bags). In Slovenia, the consumption of lightweight plastic carrier bags amounted to 85 bags per capita in 2023 In the same year, 145.9 million pieces of single-use food containers made wholly or partly of plastic and 174.4 million pieces of single-use beverage cups made wholly or partly of plastic were placed on the Slovenian market.

In the period 2003-2024, the highest exposure to ozone concentrations were detected in the Primorska region in summer where air quality measuring stations in Koper and Nova Gorica Grčna detected highest ozone concentrations in ambient air. There are some differences from year to year in a level of ozone exposure due to meteorological conditions in the warm half of the year and other regional characteristics.

The phosphorus (P) budget in agriculture decreased by 109 % in the period 1992–2024. The decline is the result of a decreased P intake with mineral and livestock fertilizers, as well as the consequence of increased P uptake by agricultural crops. The period up to 2003 was characterized by a surplus of 11 to 16 kg per hectare. Thereafter, the surpluses decreased and reached an average value of +0.4 kg P per hectare in the last five-year period. A realistic comparison of the surplus with other EU Member States is not possible.

In Slovenia, we cultivate slightly more than 8 acres (0.08 hectares) of arable land per capita, which more than third of the average in the European Union (EU), which is 22 acres of arable land per capita (data for year 2023). This area did not change significantly between 2000 and 2023, which indicates that Slovenia maintains its production potential.
