Freshwater ecosystems provide several ecological and economic services. However, these in Ethiopia are deteriorating, because of growth, unwise use pollution (eutrophication). This paper reviews existing trends eutrophication Ethiopian water bodies, identifies principal sources nutrient pollution, highlights major consequences, proposes measures to control eutrophication. The trophic state all lakes considered the current assessment ranges from eutrophic hypereutrophic. A cause is chemical...
Land use, land cover, and climate change impacts are current global challenges that affecting many sectors, like agricultural production, socio-economic development, water quality, causing fragmentation. In developing countries Uganda, rural areas with high populations dependent on agriculture the most affected. The development of sustainable management measures requires proper identification drivers environment livelihoods affected communities. This study applied drivers, pressure, state,...
<title>Abstract</title> Saline lakes are hypersensitive to changes in their water balance and therefore show amplified responses climatic land-use catchment. However, despite the resulting, often dramatic ecological consequences, saline rank low on policy agendas as they assumed support few ecosystem services levels of biodiversity. Here, we challenge this view evaluate threatened species 84 distributed across globe. We found that harbour not only aquatic biota but also a diverse range...
This study was conducted in Lake Hayq between January and December 2018. The objectives of this were to determine the growth, condition, sex ratio, fecundity, length at first sexual maturity (L50), spawning seasons common carp (Cyprinus carpio). Monthly fish samples C. carpio collected using gillnets stretched mesh sizes 4, 6, 7, 8, 10, 13 cm beach seines size 6 cm. Immediately after captured, total (TL) weight (TW) for each individual measured centimeters grams, respectively, their...
Climate change (CC) is now a global challenge due to uncertainties on the drivers and multifaceted nature of its impacts. It impacts many sectors such as agriculture, water supply, economies through temperature precipitation, affecting livelihoods. Although there are global, regional, national studies CC, their application determine local CC occurence mitigation adaptation measures not ideal. Therefore, this study aimed climate trends in Lake Kyoga Basin using standardized precipitation...
ABSTRACT The aim of the present study was to evaluate spatio-temporal variability various physical and chemical parameters water quality determine trophic state Lake Ardibo. Water samples were collected from October 2020 September 2021 at three sampling stations in four different seasons. A total 14 physico-chemical parameters, such as temperature, pH, dissolved oxygen (DO), electrical conductivity, turbidity, alkalinity, Secchi-depth, nitrate, ammonia, silicon dioxide, soluble reactive...
Rapid population growth-induced urbanization, industrialization, deforestation, settlement expansion and habitat destruction are significant drivers of LU/LC change at global scale. The uncontrolled change, specifically in developing countries like Ethiopia, poses environmental threats to water quality, biodiversity, ecosystem services. This study, therefore, examined trends the Lake Tana catchment, Ethiopia from 1993 2022, analyzed impact changes on quality identified major driving factors...
This study aimed to assess the spatial and seasonal variations of phytoplankton community in response environmental variables Lake Ardibo. The was done from October 2020 September 2021 physicochemical parameters such as water temperature, pH, dissolved oxygen, electrical conductivity, turbidity, alkalinity, Secchi-depth, nitrate, ammonium, silicon dioxide, soluble reactive phosphorus, total phosphorus were measured using standard methods. ANOVA results indicated that all except turbidity had...
Catchments for aquatic ecosystems connect to the water quality of those waterbodies. Land use land cover change activities in catchments, therefore, play a significant role determining Research on relationship between and changes has gained global prominence. Therefore, this study aimed at use, catchments L. Kyoga basin, assessing their connectedness lake’s quality. The GIS software was used determine eight major 2000, 2010, 2020. Meanwhile, data obtained through both secondary primary...
Abstract Lake Koka has several important socioeconomic uses, hydroelectric power generation, domestic water supply, irrigation, recreation and fishery. It is currently under serious threat, however, because of point nonpoint pollution inputs. The objective the present study was to examine concentration heavy metals (Mn, Cr, Pb, Zn, Cu, Ni Cd) their bioaccumulation, biomagnification factors along lake's food chain in order assess potential human ecological health risks. Water, sediment...
Water hyacinth, Eichhornia crassipes (Martius) Solms 1883, is a rampant invasive aquatic plant that recognised as one of the ten worst weeds in world. Its appearance Koka Reservoir was reported 1965 and since then it has become major threat to ecosystem. Despite numerous limnological studies on Reservoir, effects water hyacinth zooplankton not been addressed previously. To assess this, samples were collected from three weed-infested non-infested sites March July 2018. The community living,...
