This study tests if household-level outcomes—awareness, understanding, experimentation, or adoption of a technology or practice—can be influenced by small changes in the extension approach through the following pathways:
Reducing information asymmetries between men and women in (dual) households. This is tested by comparing outcomes in which information is given to a single individual to outcomes from households in which the same information is given to both the man and the woman together.
Promoting a "cooperative approach" to farming. This is tested by comparing outcomes in which information is given by a single individual to outcomes in which the same information is given by both the man and the woman as a couple.
Leveraging a "homophily effect" whereby information is more effective if it is provided to a recipient by someone of the same gender. This is tested by comparing outcomes in which the gender of the messenger and the recipient of the message is the same to outcomes in which the genders of the messenger and recipient differ.
Providing information. This is the simplest effect expected from extension, and is tested by comparing outcomes based only on the provision of information to any household member.
The study involves almost 4,000 maize farmers in Uganda in five eastern districts. The information intervention is implemented as a short video shown to farm households according to the experimental design: Videos in which the extension information messages were presented and narrated by either a man, a woman, or a couple were shown to either the man, woman, or a couple.
The video features recommended practices on maize farming, such as inorganic fertilizer use and timely weeding and proper spacing. It also promotes a more commercial approach to farming more generally, such as starting small and re-investing part of the profits.
The videos were shown to study participants in August and September, right before the start of the growing season. Farmers will be visited again at the end of the season in February 2018 to collect information on outcomes. Data from surveys conducted during these visits will be used to evaluate the effectiveness of the video interventions.
It is too early to say anything substantive about these outcomes, so stay tuned. But an initial look at data collected during the first video screenings immediately reveals the devastating impact of the fall armywormin Uganda. While a farmer might normally harvest between 600 and 800 kg of maize per acre, the armyworm infestation in the first season of 2017 has reduced yields to only about 280 kg of maize per acre.
A look at data collected immediately after the video screening also reveals some interesting insights. To check if people actually learned something by watching the video, participants completed a short test (just three multiple choice questions) related to the content. Our analysis shows that the information treatment seemed to work: Households shown a video are significantly more likely to answer the multiple-choice questions correctly. In addition, households in which the video was shown to a couple are also more likely to answer the questions correctly when compared to households in which a single individual (either the man or the woman in the household) viewed it.
