In western Uganda, researchers conducted a series of randomized evaluations that assessed the impact of introducing a combination of post-harvest services, training on agricultural best practices, and access to a market for high-quality maize on farmers’ productivity and profits. Researchers found...

Researchers conducted a randomized evaluation to test the impact of a video-mediated extension approach on the uptake of technologies recommended by the Ethiopian Ministry of Agriculture. The video-mediated instruction increased uptake through improved access to extension and farmer knowledge but...

Researchers are conducting a randomized evaluation to test whether providing traders “bonuses” for high-quality coffee affects the prices traders offer farmers for their coffee and whether this, in turn, affects farmers’ incentives to invest in the quality of their production.

In partnership with Bridges to Prosperity, the researchers are conducting a randomized evaluation across 23 districts in Rwanda to determine the impact of building footbridges on wages and agricultural technology adoption and production.

In Kenya, researchers assessed the impact of training farmers to verify seed quality on their seed purchasing decisions and productivity, and the responses of seed markets to these changes. Trained farmers became better able to detect seed quality, more selective about where they bought seeds, and...

Researchers are evaluating the effects of providing farmers with access to maize processing services that could improve maize quality on their input decisions.
