Popis: Water hyacinth was officially reported in Ethiopia in 1956 at Koka Dam and Awash River and it is considered as a constraint to the development of the country. Thus, this study was undertaken to determine Water hyacinth and associated land cover/use changes, and capture perceptions regarding community-based management to enhance its proper control/eradication in Lume and Boa districts, east Shoa zone, Ethiopia using integrated approach. The method of study included Water hyacinth and associated land use/cover change analyses, focus group discussions, discussions with experts at the district, zone and region levels and undertaking consultative workshop. The land use/land cover change analyses revealed increased area coverage by Water hyacinth from about 145.53 ha in 1986 to 2319.48 ha in 2015 with decline in the area of water bodies and wetlands. The annual rate of increase in the area of the weed was about 51.51% while water bodies and wetlands declined by about 0.49% and 1.16%, respectively. Of the 10 group discussions undertaken in the study districts with the communities, 9 of them reported water hyacinth to increase in terms of area coverage since its appearance in their areas which concurs the results obtained from satellite image analyses and they reported the weed to be very harmful to their livelihood. Furthermore, the nine group discussants disclosed water hyacinth to be of no use to them. Recommendations included developing comprehensive management strategies and action plans, analysis and defining roles of each stakeholder, awareness creation, training, institutional linkages, co-management and reduction of nutrient load in water bodies.
