Nigeria's agricultural sector has the potential to drive growth, ensure food security, and reduce poverty, but this promise is hindered by inefficient supply chains connecting farmers to markets. This book offers a thorough analysis of these critical linkages, examining why harvests often fail to reach consumers. It starts by depicting Nigeria's agricultural landscape, where smallholder farmers face poor storage, weak infrastructure, and limited market access. These issues lead to significant post-harvest losses, creating food scarcity despite agricultural plenty. The book then explores practical solutions, such as digital tools for market and financial access, and cold chain innovations to preserve perishables. It highlights the importance of supportive policies and public-private partnerships in improving infrastructure. Grounding its analysis in real examples from across Nigeria, the book shows how cooperatives, processing, and direct market links are overcoming bottlenecks. It also emphasizes the inclusion of women and youth in these value chains. Finally, it presents an integrated vision where efficient supply chains spur rural development and sustainable food systems, blending technology with context-specific solutions like better roads and storage. Written clearly for policymakers, practitioners, entrepreneurs, and academics, this book combines research with actionable insights. It serves as both a diagnosis and a roadmap for transforming Nigeria's agricultural potential into prosperity.
