UjuziKilimo is a Nairobi-based precision farming social enterprise using big data analytics on top of a sensor-based soil and farm testing IoT device and tapping into the mobile penetration advantage in Africa to provide small-holder farmers with affordable, precise and easy-to-understand farming recommendations - with the target of optimizing crop productivity and reducing hunger among African homesteads. We believe that making data actionable and usable for the small holder farmers is the best way of creating a knowledge based agricultural sector as we strive to feed the ever increasing global population.
