The Lake Tana Biosphere Reserve is located in the Amhara National Regional State approximately 563 km northwest of Addis Ababa in the north-western part of Ethiopia. The biosphere reserve comprises Lake Tana, the largest lake in Ethiopia, the main source of the Blue Nile, which provides important ecosystem services. The area is a hotspot of biodiversity, internationally known as an Important Bird Area and is of global importance for agriculturalgenetic diversity. The area is characterized by an enormous heterogeneity of land uses and natural ecosystems. It was designated in 2014 and is administered by the ANRS Bureau of Culture, Tourism and Parks Development, under the authority of the Ethiopian Ministry of Science and Technology. In 2015, the Lake Tana region was nominated as UNESCO Biosphere Reserve recognizing its national and international natural and cultural importance. Its surface area is 695,885 hectares, with its core area being 22,841 hectares, with buffer areas of 187,567 hectares, and transition areas of 485,477 hectares.
Ecological Characteristics
Lake Tana is the largest national freshwater body, accounting for 50% of the total inland waters of the country, and is the source of the Abbay of Blue Nile River. The Biosphere Reserve is an important fish resource and is home to up to 67 different species of fish of which 70% are endemic. The barbus species of Lake Tana constitute the only remaining intact species of large cyprinid fish in the world. A large number of wetlands are located all around Lake Tana, some of them being the largest and ecologically most important units in Ethiopia and in the Horn of Africa, and also form part of the Central Ethiopian Wetland Complex. These wetlands, dominated by papyrus and typha stands, are breeding, nesting and feeding grounds for very large bird populations, and provide a source of animal feed, domestic water supply, building material, fuel, food, etc. for local communities. The Biosphere Reserve is part of the Eastern Afromontane Biodiversity Hotspot and comprises four terrestrial and three freshwater ‘Key Biodiversity Areas’. At Lake Tana more than 217 different bird species have been recorded. The area is internationally renowned as Important Bird Area and the high abundances qualify areas around the lake as Ramsar site. Many Palaearctic migrant water birds depend on the lake as feeding and resting grounds, including the common crane, Northern shoveller, Black-tailed godwit, and ruff. Few patches of original forest vegetation and mountain ecosystem remain that have high plant endemism of global importance. Indigenous trees include: Sesa, Birbira, Wanza. The region is a gene centre for indigenous agricultural crops such as noug, teff. Wild coffee occurs naturally in the area, especially in the Zegie Peninsula. Four major wetland ecosystem types have been identified: Riverine freshwater wetlands, lacustrine freshwater wetlands, palustrine freshwater wetlands and agricultural flooded freshwater wetlands.
Socio-Economic Characteristics
Out of the 2,031,820 inhabitants of the proposed site, approximately 15,000 are living on the islands of Lake Tana. The area includes an array of rural settlements, as well as the city of Bahir Dar, which supports traditional land-use patterns. Agriculture forms the backbone of the economy with most of the other sectors being dependent on its strong backward and forward linkages. More than 2 million people live in the Biosphere Reserve with the Amhara people being the most populous in the area. The main economic activities are agriculture, fishing, national and international tourism and sand mining. The enhancement of production and marketing of local products from the proposed biosphere reserve through cooperatives and small scale businesses will be intensified in close collaboration with local tourism services and the hotel sector. The Papyrus is one the most economically important wetland species of the Biosphere Reserve and is used inter alia for fuel, as well as for the construction of the unique Tanqua reed boats. The area has a unique cultural, historical and aesthetic value with numerous monasteries and churches dating back to the 13th century. Culturally, the Biosphere Reserve is very important as it is home to many unique churches and monasteries of the Ethiopian Orthodox Tewahedo Church; some date back to the 13th century. These churches and monasteries contain valuable treasures of the Ethiopian Christian faith.
