Brief summary: This study seeks to promote consumption of locally sourced foods among school going children in Barbados. The study targets parents/care givers of school going children aged 18 years and below. Parents have been chosen as the target for this study because they shape the meals that their children consume through two primary routes; a) direct purchase of meal ingredients and b) political influence on school based meal programs. The study seeks to achieve this by first identifying the behavioral obstacles for consumption of locally sourced produce through exploratory and desk research and then designing interventions to address the obstacles.

Detailed description: This study will be rolled out as a digital interface experiment where the survey and intervention prompts will be programmed on OTree platform with pre-randomized assignments of the participants into either treatment or control groups. Busara Center for Behavioral Economics has partnered with a local organization named FutureBarbados who are part of the Government of Barbados. The organization will avail census data for parents with school going children below 18 years of age in Barbados. Busara will then randomly sample a pool of 1500 parents who will be sent a link to the programmed survey and intervention prompts to fill out. The process will entail first a consenting process which will be displayed on their phone screens upon opening the link. The consent information will outline clearly the purpose of their study, the length of the survey, data confidentiality, the voluntary nature of participation as well as contact information in the event they would like further clarification before making the decision to take part in the study.

Once the participants consent to take part in the study the survey will have been programmed to assign them the respective survey depending on the treatment or control assignment.

The assignments are as follows:

* Control group 1: This will involve the provision of innocuous information about food. This provides a control group that is similar to the treatment groups in terms of the amount of time and cognitive effort demanded from them. This allows for a baseline measurement of parental interest in local produce.
* Control group 2: This will involve provision of general, positive information about the use of local produce in school meals. This is a secondary control that allows for the separate estimation of the effect of increasing attention to local produce, and serves to control for demand effects of the experiment itself.
* Treatment group 1: This will include an awareness campaign designed for parents. The campaign will consist of a series of photos of healthy meals showcasing how to use local produce. The meals will be child-friendly and easy to prepare. The messaging on the campaign will include educational content on 1) the importance of shopping for local produce to support farmers and the local community rather than relying solely on imported produce. 2) Seasonality of local produce; when to use what? This is intended to support parents to plan their meals according to availability of certain local produce with the ultimate aim of obtaining a healthy diet affordably
* Treatment group 2: This will provide information promoting of an online market platform where one can order local produce to be delivered directly to their homes.
