The problem

Agricultural advisory in Sub-Saharan Africa is too often theoretical: textbook guidance disconnected from local soils, climate, workers' capacities and economics.

Our offer

Kawa Tamu offers the place, the people and the discipline to test and fine-tune what really works. Our team designs the trial, documents the process and the failures honestly, runs the statistics and delivers a paper with hard evidence, all grounded in commercial feasibility.

Block benchmark: spacing follows the UCDA/MAAIF national coffee sustainability toolkit. Alternative configurations are planted alongside to compare performance.

Robusta agroforestry planting layout: a repeating 12 by 12 metre module with Robusta at 3 by 3 metres, matoke at 6 by 6 metres, Albizia coriaria at 6 by 12 metres, Canavalia cover crop and a Ficus natalensis boundary
Benchmark: the standard configuration from the MAAIF sustainability curriculum, against which our innovative agroforestry models are compared. Repeating 12 × 12 m planting module: Robusta 3 × 3 m, matoke 6 × 6 m, Albizia coriaria 6 × 12 m, Canavalia cover crop, Ficus natalensis on the boundary.
