Rice farmer Mohammed Alhassan demonstrating how he weeds his field. Alhassan is a Tamanaa Rice Processing Factory outgrower. The factory and its outgrowers are supported by the Competitive African Rice Initiative (CARI), which aims to boost productivity and strengthen the rice value chain. The factory's operations, record keeping and outgrower relationships are in the process of being digitised through the use of PaddyBase, an app developed by Lagos start-up Crop2Cash.
