The Invisible Seed Market

The informal seed sector — village markets, trader networks, neighbor exchange, and saved seed — supplies the majority of smallholder planting material across sub-Saharan Africa. Formal certified seed systems, despite decades of investment, have consistently failed to achieve the geographic reach and social breadth necessary to serve women farmers, remote communities, and subsistence households. Yet researchers working on seed systems acknowledge a fundamental data absence: they "do not have data on what is going on in that sector — where seed is produced, where it flows, who accesses it." Without this basic mapping, interventions to improve seed quality, introduce climate-resilient varieties, or reduce seed-borne disease transmission cannot be rationally targeted.

Seed is the foundational input for food production. Variety choices made at planting lock in yield potential, drought tolerance, and disease susceptibility for an entire season. In contexts where formal seed supply reaches only a fraction of farmers — particularly women, who are disproportionately dependent on informal channels — the informal sector is not a gap in the system but the system itself. Agricultural research programs that model variety adoption, calibrate interventions, or estimate food security impacts using only formal sector data are systematically mischaracterizing how seed actually moves and who actually uses what. This blindspot compounds across every downstream intervention in the food system.

Agricultural development programs have consistently prioritized scaling formal certified seed systems as the path to delivering improved varieties at population scale. These efforts have succeeded in reaching commercially oriented, better-resourced, often male farmers with market access, while leaving informal networks — which operate on trust, local knowledge, and social reciprocity rather than commercial transaction — unaddressed. Researchers have attempted to study informal seed systems through surveys and market observation, but these methods capture point-in-time snapshots rather than network flows, and they frequently miss the actors (women traders, village seed banks, exchange networks) who operate informally precisely because formal documentation would be disadvantageous. CGIAR's own Inclusive Delivery initiative acknowledges the data gap as an active constraint on its ability to design effective seed delivery programs.

Systematic mapping of informal seed flows — using a combination of participatory network research, trader interviews, and potentially mobile-based tracking tools — would create the baseline data needed to identify leverage points: high-volume traders who could be quality checkpoints, varieties already moving at scale that are candidates for formal improvement, and social network structures through which information about new varieties might propagate. This is not primarily a technology problem. It requires sustained ethnographic and participatory research methodology adapted to informal market contexts, combined with data infrastructure capable of aggregating findings across sites and scales.

A team with network mapping or social science methods experience could design a lightweight research protocol for characterizing informal seed flows in a single crop-region combination — establishing what data can realistically be collected by community researchers with basic tools and what analytical outputs would be useful to intervention designers. A data systems team could investigate what existing mobile money, market, or agricultural extension data sources might be repurposed to trace seed movement without requiring direct survey — and what privacy and consent frameworks would be appropriate. A communications or participatory design team could work with CGIAR's Inclusive Delivery initiative to understand what information format would be actionable for national seed policy given informal sector evidence.
