Smallholder farmers produce about 70% of the world’s food and employ more than one billion people. They therefore have an important role to play in eradicating food insecurity and poverty among the world’s growing population. Although there are different digital services for smallholder farmers, the existing services lack sustainability in the agriculture context and hardly meet their needs. Data management and sharing among different agriculture stakeholders has the potential to make agriculture sustainable, but there is a need to enable access to digital services in an entire farming cycle under one roof. This paper aims to propose the design of a comprehensive data management digital framework to solve common challenges of smallholder farmers in Tanzania and other countries’ agricultural systems. We follow the design science research (DSR) method to develop an artifact that interacts with the problem context. To illustrate the framework’s applicability, we use different case studies in Tanzania.
