Development of AlternativesAs with most invasive plants, villagers on Lake Victoria’s shores may be able to eliminate the hyacinth but by making use of it, they could control the plant’s invasion, and restore some of the lake’s health.
Do you consider this as a success?Not Sure
Why? Explain briefly.Water Hyacinth has been a major problem in Lake Victoria and a lasting solution has not yet been found despite efforts by scientists, local communities and environmentalists. Some organizations however believe that the best solution is finding ways of utilizing the invasive plant rather than trying to eliminate it. This is hoped to provide an alternative source of livelihood to fishermen, who relied on fishing, as fish stocks continue to dwindle as a result of the invasive plant.
