Over the period 2014-16, the Syngenta Foundation for Sustainable Agriculture, through its SRAI 2 project with Michigan State University, commissioned seven sets of case studies.1 These examined innovative models of linking small farmers in West Africa to growing markets for valued-added agricultural products, including processed food products and high-value exports. The models, termed “partnership models” here, involved various forms of contracting with farmers, either through farmer organizations or directly with private firms. The studies aimed at identifying factors that contributed to both inclusion of small farmers and sustainability of the approaches used. This paper synthesizes key results and crosscutting lessons from those studies.
