Many agribusinesses in developing countries have incorporated smallholder farmers into their supply chains, and many market systems programmes aim to assist agribusinesses to do this in a way that benefits poor farmers. It still remains difficult, however, to access data on how this trade impacts these farmers’ livelihoods.
The Smallholder Working Group, co-convened by Grow Africa and AGRA, recently reviewed good practice with regard to how to measure the impact of agribusinesses of smallholders. This included exploring a case study on the impact measurement approach taken by SABMiller, a beverage company that relies on smallholder supply chains in developing countries for sourcing its brewing crops.
SABMiller’s approach to measuring the impacts on smallholder farmers was two-fold;
Example of Uganda deep-dive study; One of these deep-dive studies measured the impact of sorghum and barley supply chains on the livelihoods of smallholder farmers in Uganda.
Interviews were carried out with a sample of 805 farmers (including a control group of farmers outside the SAB Miller value chain) as well as other supply chain actors, such as aggregators and agents. A similar study had not been carried out before these supply chains were set up, so it was not possible to compare results against a baseline. However, the researchers spoke to farmers to understand their perceptions of changes since joining the SABMiller supply chain and they interviewed a control group of 200 sorghum farmers who were not supplying SABMiller in order to compare results. Data was collected on a range of metrics, including access to markets, farmer productivity and incomes, net crop income and household income, crop profitability, adopting of farming practices, women’s empowerment, food security, post-harvest losses as well as the business relationships between different supply chain actors.
 The combination of SABMiller plc with Anheuser Busch InBev (AB InBev) was completed on 10th October 2016.
