The study was carried out in 2010 by students on the basis of the joint project of Agrocampus Ouest in Rennes and Poznań University of Life Sciences. The aim of the study was to compare the small farms diversification in Wielkopolska (Poland) and Brittany (France) and also to compare an influence of this diversification on the viability of the production. The results revealed, that diversified business activity of the small farms, increases their incomes. In Wielkopolska most of the small farms run the agrotourist business combined with a direct sale of resources. Wielkopolska is also a region, where agrotourism is a dominant form of business at small farms. On the other hand in Brittany most of the small farms make the additional profits on a direct sale of resources and the manufactured regional products.
