Environmental indicators in Slovenia

Environmental indicators are based on graphs, maps and assessments and as such present environmental trends in Slovenia. The indicators represent one of the four pillars of our environmental reporting, and are prepared in accordance with the Environmental Protection Act. The Environmental Indicators in Slovenia website enables users to browse among 180 indicators. They are based on numerical data and they indicate the state, characteristics and trends of environmental development in Slovenia. They are prepared using a systematic approach based on data and monitoring, as shown in the information pyramid.

The quick rate of retreat of the Triglav Glacier, which began in the second half of the 20thcentury, further accelerated till the beginning of the 21st century. Due to increasing intensity of ice thinning, outcropping rocks began to emerge in the middle of the glacier, which disintegrated into two parts in 1992. In the last part of the first decade of the 21st century, the glacier has been retreating at a slower rate. The last major recession of the glacier was registered after the above average hot summer of 2003.


Changes in the size structure show that concentration processes are continuing regarding the extent of the agricultural land, while in the area of the livestock production these processes have slowed down. Nevertheless, due to its small size on average, the competitiveness of Slovenian farms is low compared to the EU–28 countries.


Slovenia is a net importer of food, as the value of food imports exceeds the value of exports. In recent years, food exports cover about 50% of imports. In the long run, the coverage of food imports by exports increases slightly. After Slovenia's accession to the EU, the value of food imports and exports increased significantly. Exports in value terms increased mainly at the expense of unprocessed agricultural products, while imports increased at the expense of processed products. Majority, i.e.


Areas, prepared for irrigation, have increased from 4,554 ha to 6,673 ha in the period 2000–2019, and their share in total utilised agricultural area from 0.9 % to 1,4 %. The water consumption per hectare of irrigated land, which strongly depends on weather conditions in each year, has decreased since 2001. In the year 2019 was used 1,030 m3 of water per hectare of irrigated land, which is 27% less than the long-term average and more than three times less than in the year 2001, when 3,199 m3/ha was used.


Slovenian groundwater bodies most polluted with nitrates are those with intergranular (alluvium) aquifers, particularly in north-eastern Slovenia. Groundwater in karst and fractured aquifers is less burdened with nitrates due to geographical conditions, low population density and less agricultural land. In the period 1998–2019, the average annual levels of nitrates in water bodies in the Sava valley, Ljubljansko barje, Savinja, Drava and Mura basins show a statistically significant downward trend. In other water bodies, nitrate levels are not statistically significant.


Inland bathing water quality in Slovenia is good and comparable with bathing water quality in other European countries.
