Analyse économique du développement des nouveaux marchés biologiques. Le cas des marchés biologiques domestiques au Kenya.

Abstract : Over the past two decades the organic agro-food system has been transformed, extending beyond Northern countries and expanding in many so-called developing countries. This dynamic was first a positioning on high added value products’ export markets. Since several years, domestic markets have emerged in a growing number of developing countries, including Kenya. This thesis attempts to shed light on the dynamics explaining these new markets’ emergence and development. The research is based on four questions. The first one concerns the way organic transactions have been organized in Nairobi. Based on neo institutional economics, we explain how, in the absence of credible certification systems, these products are able to be sold with premium. The second question deals with the conditions of producers’ access to these markets. It is common to highlight that organic domestic Kenyan markets are more profitable than conventional ones. However, some producers, who could actually sell in these markets, prefer conventional ones. Thanks to the concept of transaction costs, we show the role of negotiation and monitoring transaction costs. Chapter 3 analyses the effects of selling on organic market on crops’ diversification, as a proxy of economic and environmental sustainability. Based on microeconomics’ contributions our results confirm the positive effect of organic markets. Finally, our fourth and final chapter provides an analysis of the conditions of these markets sustainability. We propose an analysis grid combining economy of information and quality construction approach, based on Hirschman (1970) works. This grid helps us comparing different certification and verification schemes existing in Kenya. Analysis shows that the least effective scheme is the one that is bound to grow, raising the question of the sustainability of Kenyan domestic organic markets.
