This document examines the role of agricultural advisory services among innovation support services in Madagascar. It analyzes data from interviews with 115 organizations providing innovation support and characterizes 315 total support services. The results show advisory services, particularly technical advice and capacity building, predominantly make up the overall offer of innovation support services. However, supporting innovation requires a diversity of organization types and strategies, including specialization in advisory services, combining advisory with other supports, or collaborating to provide complementary services. Agricultural advisory is thus one important but not sole component of the complex system supporting agricultural innovation.
