This bulletin is based on case studies about the outsourcing of agricultural advisory services in Tanzania, Mozambique, Uganda and Mali. These experiences in Sub-Saharan Africa are unique in the sense that they emphasize close collaboration and complementary elements between the public and private sectors. The bulletin is expected to expand knowledge on outsourcing between practitioners and policy makers in SubSaharan Africa. The lessons learned from the pilot programmes in the respective countries, as well as from Uganda’s National Agricultural Advisory Services (NAADS) Programme, are expected to guide the further expansion and up-scaling of outsourcing approaches and systems.
