“…125/2014, 2014, defined as ‘Lake Tana biosphere reserve shall mean the place comprising, core, buffer, and development zones in the Lake Tana and its environs recognized with definite boundaries (Figure 3). Lake Tana Biosphere Reserve, registered on June 19, 2015, is among the fourth UNESCO world biosphere reserve sites of Ethiopia (Worku, 2017). Any development that is taking place in this area should respect Lake Tana Biosphere Reserve rules and regulation.…”

Environmental Impact of pump irrigation projects from Lake Tana (Megech - Seraba, Tana Asrate, Tana Mekonta, Tana Wenjeta, and Tana Zegie) was studied from July 2018 to February 2019. Interactions between project activities and environmental parameters were also done by a matrix, and quantitative and qualitative analysis. As a result, identified positive impacts are new job creation, the opportunity to promote traditional agriculture and income increase, whereas land, fisheries and wetland degradation, pollution, deforestation and wildlife, inefficient water use, the decline in soil fertility, erosion, sedimentation, small aquatic animal death, and cumulative impacts are negative ones. Mitigation measures for these impacts to reduce their effects to the minimum level and recommendations have been proposed so that the execution of the projects becomes a success without harming or with the least negative effect on the environment.

Bottom Sediment Characteristics of a Tropical Lake: Lake Tana, Ethiopia

et al. 2020

Sediment concentration of rivers in developing countries has been increasing greatly over the last 50 years due to the conversion of forest to continuously cultivated land with the increasing population. Few studies have addressed its effect on sedimentation and water quality of the lakes by analyzing bottom sediment characteristics. In this study, the objective was to investigate the spatial distribution (and their interrelationships) of the bottom sediment characteristics in the largest lake in Ethiopia, Lake Tana where water hyacinths have been spreading rapidly during the last decade. Sediment samples were collected from the lake bottom at 60 locations and analyzed for texture, organic matter, total nitrogen, and available phosphorus. Bottom sediment samples had a median of 75% clay, 13% silt, and 9% sand. Clay was greatest in the northwestern part and smallest in the areas near the major rivers entering or exiting the lake. Clay percentage and lake depth were strongly correlated. The mean organic matter content of bottom sediment was 16 g kg−1, total nitrogen 0.8 g kg−1, and Olsen available phosphorus 19 mg kg−1. Phosphorus concentrations peaked where water hyacinths were found in the northeastern part of the lake. This study will serve as a baseline for future water quality and sedimentation changes in Lake Tana. In particular, it might aid in explaining the spread of the water hyacinths.

“…Lake Tana is Ethiopia's largest lake possessing half (50%) of the nation's fresh water and the source of the Blue Nile supporting the lives of over 123 million people in the Nile Basin by its 60% approximate contribution to the basin (Goshu and Aynalem, 2017). Lake Tana Biosphere Reserve, registered on June 19 th , 2015, is among the fourth UNESCO world biosphere reserve sites of Ethiopia found at the altitude of 1780masl (Worku, 2017). It is the home of 37 islands but a means of livelihood for the people around the destination located in north-western Ethiopian Highlands in the Amhara National Regional State between the geographic coordinates of 10°58 ’- 12°47′N latitude and 36°45′-38°14′ E longitude (Admas et al., 2017).…”

Lake Tana is fed by the Lesser Abay, Reb, and Gumara rivers (Goshu and Aynalem, 2017); and more than 60 rivers and streams in total (Worku, 2017) with its surface area ranges from 3,000 to 3,500 km 2 depending on season and rainfall (Admas et al., 2017).…”

“…Different researches on Lake Tana regarding potentials for tourism development (Zur Heide, 2012) as well as problems giving priority to a fishery, water hyacinth infestation and many other related ecological problems were done on the present study area (Tewabe, 2015; Asmare, 2017; Worku, 2017)). Furthermore, they emphasized on the natural science dimensions of problems over the lake (Admas et al., 2017) giving less emphasis to the institutional, political and human dimensions of conservation with which the determinant factors of conservation remain uncovered.…”

This study has investigated the factors that determine the conservation of one of the major ecosystem in Ethiopia, Lake Tana Biosphere Reserve, using primarily quantitative followed by qualitative approach to provide adequate results of the problem under study. The study has employed the descriptive design and a total of 305 samples from rural households (n = 159) and tourism-related enterprises (n = 146) were selected based on a stratified random sampling technique. Samples were drawn based on their direct attachment either in their livelihood and possess a responsibility to the study area. Data were collected through questionnaires, observation, focus group discussion, unstructured interview and secondary data was consulted. Exploratory factor analysis was used to extract dimensions for environmental awareness. Binary logistic regression was used to analyze data using SPSS version 23. Ten Socio-demographic variables of samples were used as an independent variable and environmental conservation dimensions as dependent variables. The result revealed that out of the 10 variables employed in the analysis, six variables were found significant. Hence, marital status, household size, income source, household income, membership to club and resident location were found to be significant. Qualitative analysis revealed wrong reports for political consumption driven little government attention and lack of integrated natural resource management policy and plan were major factors hindering conservation. A vivid and holistic destination management policy making with enough room to stakeholders' involvement shall be a prior task for the government for better conservation of the ecosystem and sustainable development.
