Recent estimates speak about market shares between 1 to 4.25 per cent. In Belgium the share is only 1 per cent, but the market is growing exponentially. Organic farmers in Belgium often have to sell their products as conventional products because of non-efficient marketing systems. Marketing problems are also mentioned as one of the main reasons by conventional farmers for not converting. Most conventional farmers are not only rather sceptical about the long-term perspectives of getting a price premium for organic products, but consider the organisation of the supply chain as one of the main sources of uncertainty and therefore as a constraint for conversion. Therefore more efforts should be made to organise the supply chain for organic products. The problem seems to be that of the egg and the chicken: for a cost-effective supply chain a condition is to have enough producers, while for a lot of producers a cost-effective swupply chain seems to be a necessary condition to convert, mainly because of high transaction costs linked to non-efficient marketing.The current issue and full text archive of this journal is available at

Despite a fast-growing national consumer market for organic products and active governmental support for organic agriculture, organic production in Flanders has shown little growth since the late 1990s. Our discourse analytical approach offers important insights into the causes of the limited organic production capacity in Flanders complementary to more common political-institutional or actor-oriented perspectives. Our analysis reveals that for decades, a competition between two mutually exclusive organic farming discourses has hindered a collaborative effort to contribute to a growth of the organic agricultural sector by conventional and organic agricultural communities, agricultural policy makers, and food market actors. Such collaboration however, proves to be necessary to stimulate a substantial growth in organic production in a region like Flanders (Belgium). Our results suggest that facilitating the acceptance of non-competitive discourses across agricultural, political and food market stakeholders is vital to support the development of organic agriculture. By revealing the added value of discourse analysis in clarifying agro-food developments, the paper supports an adoption of multiple research approaches when studying dynamics of change in the multi-dimensional fields of agriculture and food provision.
