Mobile phones are now widely common in rural areas. Nevertheless, adoption of new digital agro-advisory applications has often been weak. Many of these new ser- vices were developed outside of their target context, leading to mismatches with farmers’ preferences regarding mobile phone usage or information access.
Adoption increases when new digital services are developed together with their end users –smallholder farmers. But how? Co-design methodologies systematically in- volve farmers and extension agents from the beginning. This helps to understand ex-isting information needs, select locally suitable technologies, and further adapt the design with the critical feedback from expected users.
