Demand-led system approaches boost early generation seed production and enhance common bean seed and grain supply in Zambia

This article describes the efforts and outcomes of increasing early generation seed (EGS) production and availability of quality seed of common bean varieties in Zambia, using a demand-led seed systems approach. The approach involved defining and ranking bean varieties based on market and farmer preferences, then investing in seed increase, catalyzing off-taker investment in grain off-taking and production, collaborative marketing campaigns, capacity building of seed producers, and strategic multi-stakeholder partnerships. The results showed that EGS production increased by 221.4%, and certified seed production increased six times from 2021 to 2023. Prioritized cultivars accounted for 88% of seed output, a path to desired variety turnover. The intervention was also associated with an increase in bean grain production of 10.2% in 2023, and bean harvest area by 11%. The demand-led system approach can improve seed availability and variety selection, and enhance common bean grain supply in Zambia, by linking EGS production with bean corridors and grain off-takers. Collaboration among stakeholders is crucial for its effective implementation and farmer training and support are essential for increased production.
