In Lake Chad, it is Typha Australis, a native cattail. Their resilience makes control a never ending process, one that needs a profit to be sustained. The profit is available in fuel, fiber, and in some places food. Food use requires caution. Aquatic weeds collect toxins like a miser hoards gold. Water hyacinth fiber has been used for many purposes ranging from mats to wicker furniture. Water hyacinth biomass has been successfully digested into biogas, and can be compressed into biomass briquettes, burned as fuel in one of the new gasifier stoves with charcoal as a byproduct. Aquatic weeds are a major driving force in worldwide desertification. They are dessication and siltation machines.
