Tourism has a significant impact on all economic activities including agriculture which has not significantly investigated. Part of agricultural and food products, domestic and imported, meets the needs of tourist spending. Tourist demand for agri-food products are supplied from the domestic production, but also from imports. Expected greater impact of tourism on the changes in the structure, but and the amount of domestic agricultural production which requires greater coherence and harmonization of tourism with agriculture and food-processing industry. Descriptive analysis of secondary data sources was conducted for the research (ie. desk-top method), and the impact of tourism on the changes in the production of selected agricultural products have been investigated using correlation analysis. Data sources used in the research are scientific and technical literature, data of the Central Bureau of Statistics and available materials on the Internet. The subject of this research is the impact of tourism on the Croatian agriculture and the research was based on the assumption that an increase in tourist spending has had no impact on the change of agricultural production in Croatia. Tourist spending can and has the potential to absorb significant amounts of domestic agricultural production and thus boost primary production, but also affect the increase of processing capacities. Research has shown that tourism is not significantly affected on the changes in the production of corn, wheat, grapes, olives, olive oil and wine, but had an impact on the production of fruits and vegetables.
