Given that insects provide high-quality animal protein that can be produced in an environmentally sustainable manner, there is an increasing interest in farming them to satisfy the growing demand for nutritious and sustainable foods. This is especially relevant in low-income countries, where insect farming can enhance livelihoods by improving dietary diversity and quality, generating cash income, and creating employment opportunities. While new farming systems are being developed and tested, there is a lack of knowledge on the drivers of successful insect farming and the impacts of this practice. This, in turn, hinder the development of appropriate policies for realizing its full potential for sustainable development. The current study aims to fill this knowledge gap by investigating the effectiveness of educational interventions in promoting insect farming for household consumption in three African countries. The study is designed as a multi-site randomized controlled trial to evaluate the impacts of agricultural training alone or in combination with nutrition education on the adoption of insect farming. In each of the three countries, ninety-nine villages will be randomly assigned to one of three arms: two treatment groups or a control group. Focusing on production (P), the first treatment covers agricultural training on insect farming and the provision of insect production starter kits. Focusing on both production and consumption (PC), the second treatment involves the same intervention components as treatment P plus additional nutrition education and insect food preparation demonstrations. The impacts of the intervention will be measured through two primary outcome variables indicating the adoption of insect farming and consumption of the farmed insects in the households.

Experimental Details


To achieve the objective of the study, specific interventions involving agricultural training for successful insect farming and nutrition education for increased insect consumption will be implemented.
Intervention Start Date
Intervention End Date

Primary Outcomes

Primary Outcomes (end points)
1) Whether farmed insects are consumed in the household, and
2) Adoption of insect farming indicated by whether the household continued insect farming until the endline survey.

The first primary outcome variable is measured through self-reported responses, while the second outcome variable is directly observed.

Secondary Outcomes

Secondary Outcomes (end points)
1) Insect farming and nutrition knowledge
2) Dietary diversity
3) Food insecurity perception
4) Perceived benefits and attitudes

Experimental Design

Experimental Design
The study involves a cluster-randomized control trial with two treatment arms. The first treatment arm focuses on insect production. It includes agricultural training on insect farming and the provision of insect production starter kits (Treatment P). The second treatment arm is focused on insect production plus insect-based food consumption. It has the same intervention components as P plus an additional component focused on nutrition education and insect cooking demonstrations (Treatment PC). There is also a control arm with no treatments (Control).
