Europe envision organic farming as a solution for sustainable agriculture. However the organic farming area has increased only from 1.8% in 1998 to 4.7 % in 2009 in European Union, still far from initial objectives. Worse, recent observations show cases of farmer withdrawal from organic farming. Madelrieux and Alavoine-Mornas studied organic farming withdrawal of 18 former organic farmers. Results show that withdrawal depends on the circumstances causing farmers to leave organic farming and what farmers learned by experience.
