Over the last decade, Sub-Saharan African countries have embarked on agricultural sector reforms. Farmers’ organizations increasingly voice the needs of their members in various form on policy-making, market access and service provision.

Based on case studies conducted in Benin, Rwanda and Tanzania, the book presents a number of best practices and lessons learned, and identifies issues related to strengthening the role of farmers’ organizations.
