While the area of land converted to organic farming remains low in France, it has increased over recent decades. The policies supporting organic conversion, the organization of the organic sector and the increase in food scares have contributed to the development of organic farming. In this context and on the basis of a survey conducted in the Paris region, this paper aims to analyze the effects of the development of organic farming in the agricultural and non-agricultural world. It shows how the spread of organic farming and its techniques can contribute to an ecologization of farming practices. This paper aims also to explain how non-farming people choose to support organic farming to favor the ecologization of their living environment. (JEL: Q01-Q15)
