Abstract

There is a growing use of mobile phones in rural areas on account of its relative inexpensiveness and lack of requirement for an urban environment. As a platform for accessing information through text messages and voice calls, farmers are able to collect agricultural information which may lead to higher productivity due to technology spillover. If the use of mobile phones contributes to the improvement of farmers’ productivity, their agricultural output level should increase. In this study, we investigate the adoption of mobile phones to obtain agricultural information and its effect on smallholder maize farmers’ production using cross-sectional data from Zambia. Understanding such causal effects is indispensable especially against the background of vision 2030. The propensity score matching (PSM) method was adopted to estimate the average treatment effect of treated of mobile phone adoption in agriculture. We found that the use of mobile phones significantly increases farmers’ productivity, by about 30%. If farmers start to adopt mobile phones to collect agricultural information, the total maize output would also increase by 30.36%, which would culminate in feeding two more people per household daily for the whole year. Therefore, we cautiously conclude that mobile phone use in agriculture serves the purpose of contributing to the fight against hunger via enhancing maize production and this is driving its popularity among smallholder farmers in rural Zambia.
