Notwithstanding an increasing demand for their derived products, roots and tubers value chains in Africa remain loose, fragmented and informal, and many market opportunities remain unexploited. Some encouraging new investment initiatives in roots and tubers value chains have recently been documented, both by improving the competitiveness of small actors of the value chains, and by building the capacity of financial services providers to design products and services that fit the specific needs of the mentioned actors. This policy brief provides recommendations for policymakers, including the development of incentives for investing in the sector, through the facilitation of the use of alternative forms of guarantees, and through strengthening the structure and organization levels of producers groups and cooperatives.
