Online from UI Library subscription., Reports a case study of efforts to control an infestation of water hyacinth in Lake Tana, largest lake in Ethiopia. Findings revealed that participatory communication was equated to a public relations activity of organizing campaigns with the local people urged to participate by providing labour contribution of harvesting and collecting the weed from the lake. The communication approach was found to be a one-way, top-down approach which does not facilitate a horizontal dialogue among stakeholders.
