Coffee is one of Rwanda’s biggest exports, yet coffee farms produce around 35% of other countries in the region. Combine this with limited data being shared with buyers on traceability, and while world-class in quality, Rwanda coffee is often undervalued.
After engaging key stakeholders in Rwanda’s coffee sector, Kumva has developed Smart Coffee Farming kits, using real-time monitoring to improve traceability and increase yields.
Sensors can be deployed on Rwandan coffee farms to measure conditions that affect soil fertility, then alert farmers where and when to apply fertiliser. As recommended by key stakeholders, sensors would collect data on weather, geography, harvesting / processing times and combine this real-time data with a farm bio, creating a blended data set that can be used to support both traceability and yield increase.
During the fermentation process, sensors can be used to monitor pH and temperature fluctuations within fermentation tanks, informing stakeholders of the optimum process time; too long or too short times can lower the quality of the coffee. A similar setup could be used during soaking to understand the conditions then inform and alert to increase the quality and value of the coffee.
Finally, during drying it is crucial to have coffee reach the correct moisture content; if not dry enough, coffee can lose value when it arrives at the buyer, or contain disease; humidity sensors could be deployed at drying areas, measuring the real-time moisture content and advising on when the drying period is completed.
