This review paper presents the results of many years’ research and field observations on ecological status of the catchment of Lake Tana in relation to the socioeconomic issues. There are a number of wetlands in Lake Tana region such as shore areas, head springs, permanent and temporary floodplains (riverine and manmade) which serve as crop production, fisheries, sand mining, wetland products harvesting,...
The water resources of the Lake Tana catchment are largely untapped. Currently, water resource development is being promoted to stimulate economic growth. This study utilized the WEAP model to determine the likely impact of a number of possible development scenarios on lake water levels. For each scenario, the model was used to simulate water demand in three sectors (i.e. irrigation, hydropower and...
This paper is based on a country report for Ethiopia prepared as a part of the ecohydrology component of IHP UNESCO’s FRIEND/Nile-phase II Project. It reviews past and current research in the Lake Tana sub-basin around the lake. The objective of the study was to determine the ecohydrological status of the Lake as a tool for integrated water resource management in improving the sustainability of the...
The anthropogenic effect on faecal and chemical pollution at Bahir Dar Gulf of Lake Tana, Ethiopia was investigated in the period of October 2006 to February 2007. Faecal and physicochemical pollution levels were significantly increased and clearly discernible in the Bahir Dar Gulf locations as compared to presumptively anthropogenic uninfluenced reference locations near the outlet of the Blue Nile...
Erosion is of great concern in the Ethiopian highlands. The objective of this study was to determine the soil erosion rates under actual farming conditions by measuring the dimensions and number of rills in 15 agricultural fields in the Debre Mewi watershed near Lake Tana, and to understand farmers’ attitudes towards land conservation through personal interviews with one-third of the watershed households...
