In both entities, one main gap in the information available is that there is no monitoring of agricultural water use, which means that neither is there any reliable data available in relation to irrigated areas. One important document for the future development of irrigation systems in RS is the irrigation strategy, which was finished in 2006 and foresees the reconstruction between 2011 and 12 of two big irrigation systems for an area of 79,000 ha, in the framework of a World Bank project. Within this project, water balancing at all potential sources for irrigation has been recommended and appropriate technical solutions proposed to ensure sustainable use of water resources. In the Una river subbasin, for instance, there are only 3 out of a possible 19 hydropower plants, which makes the Una the most under-used watercourse with its tapping potential for power generation utilized to only 1.7 per cent of possible capacity.
