The purpose of Working with Smallholders 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. The predominance of smallholders in many frontier and emerging markets makes them an integral part of agribusiness supply chains. Many firms source from smallholders or are actively seeking to source from them. Calls for fairer, more inclusive supply chains will hasten this trend.
