The purpose of this handbook is to enable the development of more sustainable, resilient and productive supply chains for agribusinesses and to illustrate the substantial development impact. Smallholder farmers are both an opportunity and a challenge for food and agribusiness companies. Many firms source from smallholders or are actively seeking to source from them. Yet the development and strengthening of smallholder supply chains remains a key challenge for many IFC agribusiness clients. Working with Smallholders handbook compiles innovative solutions and cutting-edge ideas for these challenges. The handbook incorporates a diverse collection of hands-on case studies from across the world regions covering wide variety of agribusiness sectors.
