This is one of a series of training modules developed following several workshops on agricultural innovation systems (AIS) and value chains development (VCD) organized for principle investigators of ASARECA’s programs in 2010 and 2011. The modules were compiled to assist in facilitating similar training that participant trainees may organize. The principle behind teaching and presenting the two concepts of innovation systems and VCD is based on the fact that they are strongly related, and there is opportunity for thinking and applying the two together in most agricultural programs.
