The baseline report for the Zambia Biofortified Maize Challenge Project evaluation uses data from 212 interviews of maize market actors (including smallholders, rural non-farming residents, retailers, and millers), as well as 1,013 interviews with urban shoppers. It presents findings about market actors’ and consumers’ awareness, production, purchase, and consumption of pro-Vitamin A maize.

The evaluationdesign for the Brucellosis Vaccine Challenge Project lays out the approach to assessing the project's influence in stimulating the development of an improved Brucella melitensis vaccine. Evaluators used a qualitative assessment and counterfactual disease study to examine technology development and used cost-effectiveness simulations as well.

The evaluation design for the Zambia Biofortified Maize Challenge Project presents how evaluators will assess whether the project motivates industrial maize millers to invest in and drive expansion of the pro-Vitamin A maize market. The report presents the structure-conduct-performance framework, pre-post comparison design, and data collection methods (qualitative interviews; quantitative survey of low-income urban consumers).

This report presents baseline findings for the Kenya On Farm Storage Challenge Project based on survey data from 4,765 farming households and extensive qualitative data. It describes low uptake of improved on-farm storage at baseline but identifies latent demand in the market. The report also describes farmers’ maize revenue and food security.

The evaluation design for the Nigeria Aflasafe Challenge Project lays out the approach to assess the project’s influence in stimulating a smallholder-inclusive market for Aflasafe-treated maize. Evaluators assess market impact using a structure-conduct-performance framework. To evaluate smallholder benefits, the design proposes a randomized control trial (later adapted to a quasi-experimental design).

The Kenya On-Farm Storage Challenge Project’s evaluation design report lays out the approach to assess whether the project stimulates a smallholder-inclusive market for improved on-farm storage devices. Evaluators assess impact on the market using a structure-conduct-performance framework. To evaluate resulting smallholder benefits, the report describes a short interrupted time series design.
