Market-driven transitions in the vegetable seed sector in sub-Saharan Africa

Context: Quality vegetable seed has the potential to significantly impact nutrition security in sub-Saharan Africa, as the region has the world's lowest per capita production and consumption of vegetables. Moreover, seed companies might have an important role to play, as in Asia, vegetable production and consumption increased rapidly following the expansion of the private seed sector. However, market-driven seed sector development remains contentious, with some celebrating technological advancements and others raising concerns.
Objective: This paper contributes to seed systems literature by focusing on the role of vegetable crops and diversity within the private sector. It explores the heterogeneous character of the private sector by studying how different business models of leading vegetable seed companies jointly contribute to sector development in sub-Saharan Africa. Methodology: Eighteen in-depth interviews were conducted with leading vegetable seed companies operating in the region. Qualitative tools were selected to translate individual company data into general findings; while thematic analysis was used to pinpoint a private sector perspective and ideal-type analysis was used to construct business model typologies.
Results and conclusions: The results show that seed companies collectively view seed sector development as a linear trajectory involving public and private investments to enable farmers to adopt increasingly advanced seed types, especially hybrids. In this trajectory, different companies take on different roles based on specialization in seed system functions: variety development, seed production, seed dissemination, and seed use. The coexistence of and collaboration between different (private) actors in the vegetable seed sector contribute to plurality and interaction in line with an integrated approach to seed sector development. However, it is not a static condition as company roles evolve with expanding business models in terms of seed system functions and market segments. SIGNIFICANCE: A general objective of (national) seed policies is to increase farmers' access and choice in terms of quality seed of improved varieties. Seed sector development interventions can enhance inclusivity by focusing on viable and innovative business models for niche markets in terms of farming systems and crop types.
