Data & Tools
Five decades of environmental data - our most irreplaceable asset
The Ewaso Ng'iro Dataset
Since 1976, we have monitored the Ewaso Ng'iro North basin continuously. River flows, rainfall, temperature, evaporation, wind, radiation, humidity. Real-time transmission via LoRa network. One of the longest unbroken environmental datasets in Africa.
