Doing agronomy at scale involves more than using geo-spatial data and making it available for use. TAMASA also aims to contribute to the transformation of knowledge provision infrastructures in Africa. As
government extension services are often overstretched and understaffed, mobile phone applications provide an opportunity to reach many more farmers with the agronomic advice they seek. By engaging farmers and different types of service providers (agro-dealers, extension workers, input suppliers, etc.) in the development of such applications, TAMASA enlarges the scale of independent agricultural knowledge provision, transforming the agricultural advisory landscape.

At the same time, TAMASA apps contribute to agronomic data collection at scale. The applications not only provide advice, but are simultaneously used to better understand the choices and practices of large numbers of
smallholder farmers operating in very diverse environments. For instance, they are used to map crop areas, farmer’s crop and variety choicesagronomic practices, yields, and changes in technology use. As they become more widely used and supported by private sector organisations, NGO’s and
government agencies, TAMASA apps contribute to more detailed, accurate and up-to- date agricultural statistics in Africa.

TAMASA currently develops pilot studies of applications on:
