La flambee des prix des produits agricoles de 2007/2008, suivie d'une baisse en 2009/2010, puis d'une nouvelle hausse en 2010/2011, a place la gestion de l'instabilite des prix agricoles au coeur des debats politiques. De nombreux pays en developpement ont mis en oeuvre des politiques pour limiter l'instabilite des prix agricoles et ses effets prejudiciables, sans toujours atteindre les resultats escomptes. L'analyse d'experiences recentes en Afrique montre que, pour etre efficace, chaque mesure politique suppose de satisfaire quatre conditions : elle doit s'appuyer sur des connaissances solides ; elle doit etre previsible ; son financement doit etre assure ; et sa mise en oeuvre controlee.  Soaring agricultural prices in 2007/2008, followed by decreasing prices in 2009/2010 then a new surge in late 2010/ 2011, have placed the management of agricultural price volatility at the heart of policy debates. Many developing countries have implemented policies to limit agricultural price volatility and its adverse effects, without always achieving the expected results. Analysis of recent experiences in Africa shows that in order to be effective, a policy measure must meet four conditions: it must be based on robust knowledge; it must be predictable; its funding must be secured; and its enforcement must be monitored.
