In recent times organic agriculture has been developed as a response to increasing environmental pollution, reduction of biodiversity and extinction of rural lifestyle, which brings to a series of benefits to the entire ecosystem. Considering growing number of organic farmers in Croatia, it can be concluded that family farms have recognized the potential of organic production. Using the case study of family farm Eko Sever, this thesis presents organic agriculture as a concept of sustainable farming management. The main aim of the thesis was to provide a basis for assessing future trends that would encourage the further development of organic agriculture in Croatia on the example of an organic family farm that is crucial for sustainable development of rural areas as well as ensuring healthy food. A SWOT and financial analyses of the farm were made and calculated financial indicators were used to identify future development guidelines. The profitability of organic production was determined on the basis of a financial analysis and also there were identified opportunities for further development. Further development of Eko Sever could be achieved by increasing the production of vegetables, fruits and processing agricultural products and also by investing in renewable energy sources through the measures of Rural Development Programme. Such investments would reduce costs, increase production and ensure sufficient quantity of the products for the Croatian market, but also for the export.
