The topic of the thesis is the development of ecological agriculture in Croatia with reference to Zadar County. Croatia is known for its different relief surfaces, climatic conditions and soil composition. It is known that the cultivation of various crops in Croatia is favorable precisely because of the favorable climate and soil. Considering that Croatia is a tourist country, ecological agriculture could be used for this purpose as an extremely valuable activity in order to attract a larger number of tourists, bearing in mind that recently there has been an increasing interest in healthy nutrition as well as living in a clean environment. In the territory of the Republic of Croatia, there are various associations of organic producers such as HSEP (Croatian Federation of Associations of Organic Producers), agencies such as APPRRR (Agency for Payments in Agriculture, Fisheries and Rural Development), Biotechnicon for the implementation of control activities in the field of organic agriculture and various other organizations and companies in the field of ecological agriculture. The European Union defines and proposes different types of incentives and subsidies intended for farmers who are ultimately enabled to use them for the purpose of developing ecological agriculture in Croatia. The aforementioned organizations make it easier for farmers to access information about current tenders for compensation, and carry out their implementation. Ecological agriculture in Zadar County is interesting to observe despite the fact that it is an area that includes different types of relief surfaces, respectively areas that affect different climates.
