Transparent supply chains, empowered communities.
Zamba engages farmers as active partners and equips coordinators with the tools to manage education, scheduling, and participation — building secure and transparent supply chains together.
A plot is drawn. A farmer is named.
The first byte of the network is a boundary. Zamba registers the plot, the farmer and the household behind it — so a lot number never floats free of a person.
Every record carries a name, a location and a history: who planted, who trained, who weighed, who signed. Data stops being abstract and becomes a person with a polygon.
- Polygon Plot boundary, GPS coordinates and area in hectares, captured in the field.
- Identity Farmer profile, household members and cooperative membership.
- Crop Varietal, planting date and expected yield per plot.
A second thread arrives.
A coordinator walks the last kilometre. Training sessions, planting calendars and attendance — each one a tick along the line.
Zamba gives coordinators the tools to schedule, teach and record participation, so knowledge is logged with the same care as a harvest.
Weighed. Tagged. The line forks.
On harvest day the thread stops being a straight line. One plot becomes one lot, and that lot carries its whole history with it.
- WeightKilos recorded at the scale, tied to the plot and the farmer.
- MoistureQuality readings captured before the lot leaves the shed.
- TimestampDate, time and the coordinator who witnessed the handover.
Every handoff leaves a mark.
Collection, fermentation, drying, milling, export. The line crosses a map and changes weight at every hand — and none of those hands are anonymous.
Each passage is signed. Compliance stops being paperwork filed after the fact and becomes a record written while the work happens.
- SignedNamed custodian at every transfer point.
- SealedLot integrity checked against the origin record.
- SharedOne truth visible to co-op, exporter and buyer.
The screen resolves into Marta’s name.
A buyer scans a lot. What comes back is not a compliance certificate — it is a person, a hillside, and eleven training sessions attended.
“We used to buy a lot number. Now we buy a relationship we can point to on a map.”

Value flows backward.
The same thread that carried a lot to a buyer carries payment, training and infrastructure back to the plot. One line in, one canopy out.

Farmers
Registered by name, paid on verified weight, and recognised for the training they complete — not just the volume they deliver.
Coordinators
Schedules, attendance and field records in one place. Less paperwork in the evening, more time on the hillside.
Buyers & partners
Origin, practice and custody evidence they can open themselves — auditable without a single follow-up email.
Impact written at the same time as the record.
Every verified lot funds the next training cycle, the next scale, the next drying bed. The ledger is not a report written afterwards — it is the work itself, in order.
“My name is on the bag. That changed how I farm.”

Lot-level origin evidence, geolocation, and practice records — assembled as a by-product of daily coordination rather than a season-end scramble.
