Tana, the vast, 832-square-mile body of water is Ethiopia's largest lake and is packed with ecological, cultural and historical charm. It is situated in the highlands of Ethiopia’s second-largest region, Amhara administrative state. The lake is one of Africa's most unique wetland ecosystems and the source of 50 percent of Ethiopia's freshwater. But, the lake has been infested with water hyacinth, a fast-growing invasive water weed native to South America and locally known as Emboch. As the menacing water hyacinth threatens to clog the entire lake, their survival is at stake as well as the livelihoods of all who live near and depend on Lake Tana as a natural resource. People across Ethiopia have been lending their hands to help remove the waterweed. This week on his visit to the Emboch infested lake the Addis Ababa deputy mayor Ato Takele Uma stated that the Addis Ababa City Administration will be donating Ten million birr the multifaceted efforts to save lake Tana.
