Protection of agricultural lands is an important factor in preserving quality lands and
increasing food production. The areas that have undergone consolidations and include
operational drainage and irrigation systems are of special importance as they have impact
on the quality and quantity of the harvest. The significance of these lands has been
demonstrated by using the grading criterion, which is defined by the Rules for specification
of the proposal pertaining to the Permanently protected agricultural land (PPAL). Using the
ArcGIS program we have designed a basic chart that includes the areas, which are
potentially suitable for the implementation of the PPAL proposal. The total area of lands
that are suitable for implementing the PPAL from the standpoint of the executed
consolidations and operational drainage and irrigation systems, is 60,030.14 ha. The results
have shown that most of the lands suitable for the PPAL are situated in the Pomurje region
(26.050 ha), while the highest scores regarding suitability are reached in the Coastal-Karst
region. Most of the areas (86,62 %) that have been consolidated and have operational
drainage and irrigation systems are located on strategically very important areas for
agriculture and food production. The areas with a high land credit ratings include the
majority of the areas (36,17 %), which meet the criteria of the conditions that we have
studied. The highest credit ratings (68 CR) are reached by the lands in the Coastal-Karst
region, while the lands of the Littoral-Inner Carniola region are the worst in this regard (46
CR). Considering the grading criterion, the highest amount of points is attained by the
lands, which include the already built irrigation systems (13 points), and these are followed
by the lands, which include the lands with drainage systems (10 points) and finally the
lands, which have been consolidated (9 points).
