The AgResults Kenya On-Farm Storage Project was a four-year, US $12 million project designed to incentivize private sector companies to develop, market, and sell new, or redesigned, on-farm storage devices to smallholder farmers. The goal was technology, marketing, and distribution agnostic. Instead, companies werre encouraged to consider cost and storage effectiveness for smallholder farmers, and the economic benefit to smallholder farmers and beyond, as they worked to meet prize thresholds for device sales. The project ran from 2014 to 2018, with final awards in October 2018.
Post-harvest grain losses in the developing world lead to lower incomes and food insecurity among smallholder farmers. This problem is particularly acute in Sub-Saharan Africa, where post-harvest losses are estimated at US $1.6 billion per year, or about 13.5 percent of the total value of grain production. Insufficient on-farm storage often forces farmers to sell their crops right after harvest, causing a surge in supply that lowers prices for their maize. While private sector solutions to post-harvest losses exist, they are often too expensive or not accessible to smallholder farmers across the developing world. In addition, in Kenya the presence of large grain borer pests in certain areas is particularly damaging to traditionally-stored grain.
The project's prize incentive will encourage private sector actors to develop distribution networks and marketing strategies to promote their improved on-farm storage products to farmers, who through increased familiarity will invest in improved storage. Increased use of on-farm storage devices will lead farmers to store more grain with fewer losses, reducing purchases of grain and improving household incomes and food security.
The Project aimed to improve smallholder food security by raising awareness about the role of on-farm storage in reducing post-harvest losses and improving access to improved storage devices. Adoption of improved devices was expected to reduce grain loss and make more grain available for consumption. It would also reduce smallholder households’ pesticide exposure to the extent that most of the storage technologies do not require pesticide dusting. Finally, to the extent that the storage solutions allow smallholders to safely store grain for longer periods, increased storage adoption would allow farmers to sell grain at better prices, resulting in increased revenue.
AgResults expected to achieve the following by the end of the project:

In Kenya, the Evaluator is using an interrupted time series impact evaluation design to assess the project’s impact on smallholders. This approach tracks the key outcomes over time before, during, and after the project. To assess impact of the project on the market for storage solutions, they employ primarily qualitative research guided by the structure conduct and performance paradigm.
The Evaluator carried out the first phase of the baseline in 2014, with reference to the 2013 harvest. The second phase of the baseline was in 2015, with reference to the 2014 harvest. Endline data collection finished in September 2018, and evaluation findings are forthcoming.
