Following the food price crisis in 2008, African governments implemented policies aiming at crowding in investment in rice value chain upgrading to help domestic rice compete with imports. This study assess the state of rice value chain upgrading in West Africa by reviewing evidence on rice millers’ investment in semi-industrial and industrial milling technologies, contract farming and vertical integration during the post-crisis period 2009–2019. We find that upgrading is more dynamic in countries with high rice production and import bills and limited comparative advantage in demand.
Society’s learning capacity in the field of sustainable land resource management is at stake and more emphasis on knowledge management is needed to guarantee that the accumulated knowledge is shared in such a way that the right actors have appropriate knowledge at the right time to take the best decisions. Efficient policies governing structures for national and regional knowledge management need to be formulated and the working procedures of the various actors in the field need to be defined more sharply.
Les démarches paysannes de co-construction d’inno- vations des systèmes agricoles sont apparues depuis soixante-dix ans dans plusieurs régions du monde et ont constitué un tournant dans la manière d’aborder le conseil agricole. En effet, construites en réaction à un mode de conseil agricole "vertical", qui repose sur la transmission des connaissances du technicien à l’agriculteur, ces démarches alternatives ont pour but le développement des paysan(ne)s et de leurs capa- cités à rechercher par eux-mêmes les solutions à leurs problèmes.
