Abstract Background Even though wetlands are essential in enhancing water quality and providing recreation entertainment opportunities urban areas, their values overlooked by the decision-makers. Underestimation of economic value wetland ecosystem services contributes to continuing deterioration inevitable loss. Investigating changes service (ESV) can provide crucial information for decision-making. This study, therefore, analyzes temporal spatial land-use/land-cover (LULC) change patterns...
Water hyacinth has been progressively advanced in Lake Tana since 2011 and covered vast areas of the lakeshore. The aim this study was to assess how lakeshore by weed mats affected socioeconomic local community. based on a survey 405 households, 8 group discussions interviews 15 key informants conducted from January March 2018. results revealed that crop production, livestock feed supply, water fishing, health people were impacted negatively infestation hyacinth. range problems caused...
Small-scale pond aquaculture has been practiced in various parts of the Lake Tana basin. However, its establishment and expansion have carried out regardless suitability locations terms land, water, socioeconomic other inputs available to development. In recent years, there is also an increased demand for product, government private institutions given much attention sector. response this need, it necessary evaluate potential sites based on biophysical indicators. Consequently, GIS-based site...
Developing multi-metric indices (MMIs) as a tool for inland water ecosystem assessment has attracted the attention of global scientific community. The number studies, which developed macroinvertebrate-based wetlands, however, was very limited. Thus, more work is needed to refine and implement it depending on ecological contexts wetlands. On top this, we based macroinvertebrate assemblages that could be used health wetlands are impacted by agricultural activities in North-western Ethiopia....
This study evaluates the effect of anthropogenic activities on Infranz Wetland biodiversity in Lake Tana area. Plant data were collected from quadrants that established transect lines and macroinvertebrates using 500 μm mesh size. A survey with 386 households, four focus group discussions 24 key informant interviews conducted to capture socioeconomic data. Shannon-Wiener diversity index, species percentage distribution dominance, regeneration status ecological importance index computed...
There is an increasing need globally to establish relationships among flow, ecology, and livelihoods make informed decisions about environmental flows. This paper aimed the ecological foundation for a holistic flow assessment method in Gumara River that flows into Lake Tana Ethiopia Blue Nile River. First, conditions (fish, macro-invertebrate, riparian vegetation, physicochemical) of river system were characterized, followed by determining hydrological condition finally linking components....
Abstract Oreochromis niloticus is the dominant commercial fish in Lake Tana region. However, its fishery progressively declining over time. Little or no updated information exists on population dynamics and exploitation patterns of species, which crucial to guide sustainable management. Accordingly, purpose present study was generate essential biological parameters growth, mortality stock status O. niloticus, using length‐frequency data collected monthly from catches 1 year (2014–2015). The...
Shore area wetlands (lacustrine fringe) play a critical role as ecotones that support biodiversity, provide habitats for spawning and refuge, exhibit high levels of primary productivity. They facilitate significant exchanges materials between aquatic terrestrial ecosystems. To effectively manage preserve these important resources, it is essential to understand their distribution, size, dynamic changes. This study aimed create an accurate map shoreline using multi-temporal multi-source data,...
Currently, the demand of human population for more land, water, and other natural resources from wildlife habitats is increasing all over world. Such intense pressure results in conflict with impacts affect both parties negatively. The human-hippo poses a serious problem local farmers' livelihoods hippo conservation. To date, extent poorly documented Ethiopia. Specifically, conflicts around Lake Tana Biosphere Reserve (LTBR) unknown. Therefore, this study aimed to investigate conflict,...
