"To contribute to the debate with such context-specific knowledge and insights, NWO-WOTRO Science for Global Development commissioned a synthesis study. This study explored how a selection of research projects funded by the Food & Business (F&B) Research programme have directly or indirectly addressed key opportunities and constraints of sustainable inclusive business initiatives. The synthesis included 13 interdisciplinary research projects, which shared the long-term objective of contributing to improved food and nutrition security of marginalised and vulnerable groups. Based on this study, this paper presents new insights into the different business processes and innovations of, particularly, small-scale producers and entrepreneurs in the agri-business sectors of countries across sub-Saharan Africa and southeast Asia."
