review · Diversity
Eichhornia crassipes, also known as water hyacinth, is a harmful aquatic weed that has spread globally, causing significant ecological and economic damage. Originating in the Amazon basin, it has spread to tropical and subtropical regions, obstructing water movement, limiting sunlight, and reducing oxygen levels. Control measures for E. crassipes include chemical, mechanical, and biological methods. Chemical controls are cost-effective but present environmental hazards, whereas mechanical removal is effective but expensive and labor-intensive. Lastly, biological control uses natural predators to reduce weeds. Despite its significant costs, E. crassipes has potential applications in bioenergy, biofertilizer production, and wastewater treatment. This review includes an overview of E. crassipes’ biology, reproductive strategies, socioeconomic impact, and management approaches, as well as an exploration of its potential benefits in Africa’s sub-Saharan region, especially South Africa.
