Abstract
Home-grown school feeding programs can make food systems more resilient by stabilizing local markets through a large and predictable demand. Governments and UN agencies like the World Food Programme (WFP) increasingly rely on domestic procurement for school meal programs (as opposed to imported foods), connecting local farmers to markets through cooperatives and aggregators, and enhancing their capacity to meet the quality and volume requirements of school meal contracts. However, there is limited evidence quantifying the impact of such programs on smallholder farmers.

This impact evaluation is studying a farmer support package provided by WFP in the context of a school meals program in Madagascar. The farmer support and school meals programs are part of the World Bank's Food Systems Resilience Program (FSRP) implemented in collaboration with the Ministry of Agriculture and Livestock. In this evaluation, we aim to quantify the impact of an agricultural support package provided to farmer cooperatives who are targeted for supplying food into the school meals program. The support package includes agricultural inputs, trainings on production, harvesting, storage, and marketing, and infrastructure including mechanized tools and storage facilities. Outcomes of interest include farmer practices, productivity, sales, and revenues, and food security.

The primary research question of the evaluation is: to what extent does the provision of agricultural interventions from the program contribute to farmers’ outcomes and their integration into the home-grown school feeding program supply chain?

Experimental Design

Experimental Design
We conduct a randomized control trial of farmer cooperatives to receive the agricultural support package. Due to budget constraints, the program could not reach all eligible farmers and cooperatives. We randomly assign 172 cooperatives containing 6,060 farmers into the treatment group, and 100 cooperatives with 3,426 farmers into the control. An additional 385 cooperatives were not part of the IE sample but were added to a waitlist for the program to enroll should they have sufficient funds.

Experiment Characteristics

Sample size: planned number of clusters
272 cooperatives
Sample size: planned number of observations
There will be a maximum of 9,486 farmers in the experiment. Surveys are planned with a sample of 2,000 farmers in 200 cooperatives, contingent on budget.
Sample size (or number of clusters) by treatment arms
A maximum of 6,060 farmers from 172 cooperatives in the treatment group, 3,426 farmers from 100 cooperatives in the control group. For the survey, a sample of 2,000 farmers from 200 cooperatives is planned, with 1,000 farmers from 100 cooperatives in each of the treatment and control groups.
