A working coffee estate built for research
RegAg Research Estate
Partner on regenerative research and social compliance
Agricultural advisory in Sub-Saharan Africa is too often theoretical: textbook guidance disconnected from local soils, climate, workers' capacities and economics.
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.

Invested, running and ready to experiment
Land secured. 10 of 30 acres planted. 10 to 20 staff and a nursery on site.
Research blocks on the remaining 20 acres, then scaling through sister farms and a network of nearby smallholders.
How the estate is farmed
- 0 from Y4Low herbicide after establishmentCover cropping replaces herbicide, with zero use from Year 4.
- 10% areaEnvironmental buffer zonesAn indigenous tree corridor along the perimeter.
- On siteNutrient recyclingMinimal dependency on bought fertilizer.
- 20–30%Indigenous shade tree canopyMore than 10 indigenous tree species on the farm.
- IntegratedEnterprise integrationApiary, livestock and plantain alongside the coffee.
Block benchmark: spacing follows the UCDA/MAAIF national coffee sustainability toolkit. Alternative configurations are planted alongside to compare performance.
