Sažetak
Protection and management of subsurface drainage systems on agricultural land in the Republic of Croatia is regulated by the basic laws, Water Management Act (Official Gazette 153/09, 130/11, 56/13, 14/14), Water Management Financing Act ((Official Gazette 153/09, 90/11, 56/13, 154/14) and Agricultural Land Act (Official Gazette 39/13, 48/15). Appreciable potentials for the development of agricultural production in the Republic of Croatia are involved in the need and possibility of revitalization of subsurface drainage systems, constructed on a total agricultural area (land) of 167, 174.50 hectares. In the total of 2, 326, 220.60 hectares of agricultural land in Croatia, the share of agricultural land on which subsurface drainage systems - pipe drainage combined with open channels (drained land) are built is 7.18 %, while its share in 833, 239.90 hectares of overall state land is 20.06%. Of the total length of 9, 151.99 km of ameliorative open channels of orders III and IV, constructed on drained agricultural land, 5, 157.08 km or 56.35 % were revitalized by 2012 while 3, 994.99 km or 43.65 % are still unrestored. High degree of subsurface drainage system functionality has been determined on 43, 229.71 hectares or 25.85 %, medium on 18, 941.68 hectares or 11.33 % and low degree on 105, 002.84 hectares or on 62.82 % of total drained land (167, 174.50 hectares). According to the order of priority of system revitalization and regular maintenance per counties and on national level, the first (I) level includes 72, 578.25 hectares or 43.41 %, the second (II) 81, 593.18 hectares or 48.82 % and the third (III) level 13, 003.07 hectares or 7.77 % of drained areas (land). Further revitalization and regular maintenance of subsurface drainage systems combined with open ameliorative channels of orders III and IV on agricultural land in the Republic of Croatia require financial input of about 200, 305, 545.00 EUR.
