The master%s thesis evaluates agriculture environmental sustainability in the spatial units of underground water in the areas of the 21 so-called groundwater bodies (GWB) in Slovenia and elsewhere in relation to the three dominant types of aquifer porosity in order to strategically direct measures for sustainable management and monitoring of underground water areas. Slovenia is characterized by a large proportion of naturally and environmentally significant areas. This led to the search for interdependence between the assessment of agriculture environmental sustainability and the representation of a.) utilized agricultural areas (UAA) in ecologically important areas and b.) water protection areas (WPA). Due to the strategic promotion of organic farming in WPA we have also attempted to find a link between the level of agriculture environmental sustainability and c.) the organically cultivated farmland on the nine GWB areas with predominant intergranular porosity aquifiers. Since the agricultural policy strives for a greater environmental sustainability of agriculture, also through a variety of actions within the rural development program (RDP), we analyze the implementation of the selected agri-environmental payments (AEP) in 2014 on the alluvial plains of porous aquifers in Slovenia. In general, the agriculture is rated as least environmentally sustainable in the areas of intergranular porosity aquifers and most environmentally sustainable in areas with predominant karst porosity type of aquifers. Comparison of individual GWB areas shows greater differences in the degree of agriculture environmental sustainability. The relationship between the index of environmental sustainability and the three selected variables (UAA EPO, WPA and organically cultivated farmland) does not exist and was not statistically significant. The involvement of the utilized agricultural areas (UAA) in the selected agri-environmental payments on five groundwater body (GWB) areas in Slovenian alluvial plains with intergranular porosity aquifers in 2014 was, with the exception of the sub-measure organic farming, higher than the balance of the situation in Slovenia as a whole, but there are significant differences between the individual GWB areas.
