The problem

Water hyacinth has invaded the lake which is causing huge problems for the fishermen who depend on it for their livelihoods.

The thick mats of Water hyacinth (Eichhornia crassipes) limit access to the most commonly used fishing grounds. When fishermen try to work around the invasive weed, their nets often become entangled and tear.

Equipment is expensive, and many fisherman cannot afford to replace their damaged nets. 

Water hyacinth clogs irrigation systems, which compromised drinking water supplies, and can lead to a reduction in crop yields.
