Kigali Agri Estates — Tomato Production
Rwanda, East Africa
Challenge
The farm was losing 35% of its water to surface runoff and evaporation using flood irrigation across 40 hectares of tomato fields.
Solution
Installed a full drip irrigation network with soil moisture sensors and AI scheduling. Integrated a weather station to pause irrigation ahead of forecast rain.
Results
- ✓38% reduction in water consumption
- ✓Tomato yield increased by 32%
- ✓System paid back in 1 growing season
- ✓Labour hours for irrigation reduced by 60%

GreenVale Farms — Multi-Crop Operation
Kenya, East Africa
Challenge
Managing irrigation across three separate sites (maize, vegetables, and wheat) was time-consuming and inconsistent, leading to uneven yields.
Solution
Deployed remote monitoring across all three sites with centralised dashboard. Smart valves and LoRaWAN connectivity enabled full control from a single phone.
Results
- ✓3 sites managed from one mobile app
- ✓Leak detected and resolved within 2 hours
- ✓Overall water use down 41%
- ✓Yield consistency improved across all crops

Rift Valley Produce — Rapid Deployment
Ethiopia, East Africa
Challenge
A new 120-hectare farm needed a full irrigation system operational before the planting window — with only 5 weeks available.
Solution
Rak Investment completed soil assessment, system design, full drip installation, and staff training in 5 days. Remote monitoring was live on day 6.
Results
- ✓Full installation in 5 days
- ✓Staff trained and independent in week 2
- ✓First harvest exceeded projections by 28%
- ✓Ongoing remote support with zero site visits needed

Sahel Irrigated Agriculture — Scale-Up
Senegal, West Africa
Challenge
After a successful pilot on 20 hectares, the cooperative needed to scale to 120 hectares while maintaining water efficiency and staying within a tight budget.
Solution
Phased rollout using modular drip systems. ROI analytics from the pilot were used to secure a development bank loan for the expansion.
Results
- ✓Scaled from 20 to 120 ha in 2 years
- ✓ROI data enabled bank financing
- ✓Water efficiency maintained at scale
- ✓200+ smallholder families benefited
