This document discusses developing sustainable seed production and delivery systems for drought-prone areas in sub-Saharan Africa and Asia, using groundnut in West and Central Africa as a case study. It outlines current informal and formal seed systems, approaches to seed production tested in Mali, Niger and Nigeria, and the costs and challenges of seed production and small-pack sales. Key lessons learned include strengthening community-based organizations for seed production and delivery, training agro-dealers in marketing, and integrating seed and grain markets.
