Producer organisations (POs) form the interface between farmers and their economic, social, and institutional environments. The involvement of POs in the provision of rural advisory services (RAS) has been identified as a solution to the limitations of both the hierarchical public sector extension system and market- driven private sector extension systems. POs can make a positive contribution by articulating the demands and needs of their members for RAS, and directly or indirectly ensuring that these services are supplied in an efficient and sustainable way. However, not all POs have the required capacities to carry out all these functions.
