eKichabi v2: Designing and Scaling a Dual-Platform Agricultural Technology in Rural Tanzania
arxiv(2024)
摘要
Although farmers in Sub-Saharan Africa are accessing feature phones and
smartphones at historically high rates, they face challenges finding a robust
network of agricultural contacts. With collaborators, we conduct a quantitative
survey of 1014 agricultural households in Kagera, Tanzania to characterize
technology access, use, and comfort levels in the region. Recognizing the
paucity of research on dual-platform technologies that cater to both feature
phone and smartphone users, we develop and deploy eKichabi v2, a searchable
directory of 9833 agriculture-related enterprises accessible via a USSD
application and an Android application. To bridge the gap in affordances
between the two applications, we conduct a mixed methods pilot leveraging
mobile money agents as intermediators for our USSD application's users. Through
our investigations, we identify the advantages, obstacles, and critical
considerations in the design, implementation, and scalability of agricultural
information systems tailored to both feature phone and smartphone users in
Sub-Saharan Africa.
