Abstract: To improve resistance to upcoming vulnerabilities to climate change and cope with rising food demand smallholders in Sub-Saharan Africa need to upgrade their local food systems. Upgrading strategies (UPS) within existing food value chains have the potential to secure food at the local to regional level. In this paper, we determined the roles of actors and their interlinkages and motivations in UPS, and identified possible success factors of group performance within different UPS in Tanzania: a) tied ridges, b) optimised market-oriented grain storage, c) maize sheller and d) millet thresher. We used individual interviews, via the social network analysis tool Net-Map, as well as focus group discussions. The results show that actors’ motivations for participating in a UPS group differed between groups and between actors. Important success factors derived from these findings were favorable village locations followed by sociability and personal contact among stakeholders and with researchers. These results provide the basis for future strategic planning that will enhance participation and a potential up-scaling.
