After 2012, the volume of built-up areas in Slovenia continues to increase, representing 5.6% of the land use structure in 2019. In this period, built-up areas were predominantly spread to grasslands (47%), forests (21%) and permanent crops (13%), while in the period 2012–2019 the total volume of built-up areas increased by 3,966 ha. Existing data sources in Slovenia do not yet enable the evaluation of the actual loss of land for the needs of construction.


In most aquifers in Slovenia, levels of plant protection products and their degradation products (metabolites) indicate a decreasing trend, which is mainly due to the decreased concentrations of atrazine and its metabolite desethylatrazine. The number of individual active substances and their degradation products exceeding the 0.1 µg/l threshold value for individual active substances is also decreasing.
