Why the Blue Nile Carries Brown Waters

Soil particles that erode from Ethiopian slopes end up in the Blue Nile, which carries them into Sudan. The loss of the soil comes at a great cost to Ethiopian farmers, while the accumulation of the soil in water reservoirs and irrigation canals is a nuisance for farmers in Sudan.

Hermen Smit and Yasir Salih from UNESCO-IHE explain this phenomenon, and talk about their research that aims to help trace soil sediments in rivers back to their point of origin. With this information, soil conservation efforts can be planned more effectively.
