In this article from Next Billion, authors Chris Wayne and Coco Lim discuss the need to rethink the traditional concept of scale in agribusiness, especially in the context of impact investing, and how agribusiness can reach smallholders. They reference the GIIN's impact performance benchmark tool IRIS+, writing that, "these conversations and our related experience show that the average agribusiness can expect to reach between 5,000 and 10,000 smallholders. The GIIN’s impact performance benchmark for agriculture, available through IRIS+, backs this up: Across investors who reported, the average portfolio agribusiness reaches 5,643 smallholders."
