The study used the innovation system approach to ascertain the intensity and trends of linkages among key actors in the climate change and food security innovation system in Nigeria, Sierra Leone and Liberia. Data were collected through the use of semi structured interview schedule, key informant interviews and focus group discussions (FGDs) and analyzed using percentages, mean scores and trend analysis. Only 1.8% of the
farmers from Nigeria, 2.5% from Sierra Leone and 0.7% from Liberia possessed special training on climate change adaptation and food security issues. The presence of local collaboration among actors was higher in Nigeria than in Sierra Leone and Liberia. There was nonexistence of overseas linkages with majority (89.0% for Nigeria; 98.0 for Sierra Leone and 96.8% for Liberia) of the farmers across the three countries. The intensity of linkages / collaborations existing among actors in the enterprise domain, in the three countries, outweighs that with other domains, with higher collaborations existing among the small-scale farmers and famers’ associations. However, there was a perceived increase in the trend of linkage between farmers and R & D institutions in Nigeria between 2007 and 2009, with a linkage index of more than 2. There was also an increasing higher linkage index (of more than 2) between farmers and technology delivery institutions in Nigeria than in
Sierra Leone and Liberia, but a low linkage index of less than 2 between farmers and policy making bodies for all the countries. Poor generation of innovations over the past ten years and poor domestic support for climate change adaptation and food security in the West African sub-region were identified. The study points to the need to intensify the collaboration efforts, between local and foreign partners, as this will bring about the
generation of better and improved innovations on food security and adaptive measures.
