The polluting effects of organic farm wastes can occur in a number of different ways and therefore require a broad range of approaches to control. For example, all watercourses (notably lakes, ponds, rivers, streams and field ditches) adjacent to the production, storage or application of organic wastes are potentially at risk of point source pollution. This risk is different from the diffuse pollution that occurs when the microbial breakdown of manure applied to the soil occurs out of phase with the N uptake of a growing crop and leads to nitrate leaching. Bosnia and Herzegovina is divided into basic river basins as follows: Una, Vrbas, Bosna and Drina flow to the Sava River, which drains into the Danube, while the Neretva, Trebisnjica and Cetina flow to the Adriatic Sea. The biggest emission of organic pollution, then nitrogen and phosphorous is from the Bosna River basin (around 20%). This is followed by Una (15%), Sava (13%), Drina (12.5%), and Vrbas (around 10%). About 30% of above mentioned pollutants goes to the catchment of Adriatic Sea. The spatial distribution of emission is in accordance with the size of the river basin, and the size of the river basin is in accordance with other parameters (population, agricultural activities, cattle-breeding). Exceptions are the river basins of Sava and Ukrina with a bigger concentration of population and more intensive agricultural activities.

Basic principles, methodological approach to the CORINE Land Cover database–revision and correction of the CORINE 2000 (the first inventory) and preparation of the CLC2006 database are shown. The CORINE Land Cover 2006 project in Bosnia and Herzegovina (CLC2000 and CLC2006) is used as a main source of data in this paper. Special attention will be given to the metodological approach in identifying land use changes, land cover between 2000-2006. Bearing in mind that land use changes have been produced by using GIS technology, this work present GIS as a tool, while various possibilities of this tool regarding data analysis presented as well. The possibility of using the CORINE 2006 in land use planning processes in B&H is presented.
