Wetlands are catchment life support systems with diverse ecological and socio-economic functions. They have played a significant role in the growth of African human civilisations and cultural development, and today contribute billions of US dollars’ worth of ecosystem services to the people of Ethiopia. Ethiopia exhibits both natural and man-made wetland types that cover up to 2% of its land surface. They are, however, under threat from excessive pressures that are both ecologically and socially driven. The objective of this study was to analyse the state of ecosystem services provision of the Ethiopian wetlands, with a novel application of Ostrom’s Socio-ecological Systems Framework (SESF), taking Boyo Wetland as a case study. Household surveys, focus group discussions and stakeholder analysis methods were applied to satisfy the data needs of SESF. Insufficient knowledge of actors on wetland ecosystem services, weak governance and limited self-organisation among actors are highlighted as the major reasons contributing to the unsustainable use of wetlands. When the use of Boyo Wetland’s ecosystem services was evaluated using the SESF, it was evident that unsustainable resource use practices are widespread. These findings could be used to inform national policy on wetlands and local strategies for the sustainable use of wetland resources by direct or indirect users at different levels.

AbstractDespite Africa experiencing a substantial rise in inadequately managed agricultural practices, studies examining the effects of these activities on the functional organisation of macroinvertebrates in tropical streams are underdeveloped. The responses of Ephemeroptera, Plecoptera and Trichoptera (EPTs) functional feeding groups (FFGs) to agricultural pollution were investigated in the Kat River, Eastern Cape, South Africa, to identify potential FFG indicators. Physicochemical parameters and macroinvertebrates were sampled from eight sites delineated into four land-use impact categories (highly impacted, HIC; impacted category, IC; moderately impacted, MIC; and least impacted, LIC) based on the percentage of agricultural land cover. The Permutational multivariate analyses of variance (PERMANOVA) results revealed land use (F = 4.2, 3.62; p < 0.05) and season (F = 2.89, p < 0.03) influenced FFGs in the river, with shredder abundances decreasing with increasing agricultural stress. Conversely, collectors, predators and scrapers were tolerant of agricultural disturbance. Nutrient variables (NO3-N, NO2-N and NH4-N), canopy and depth were the critical variables that affected FFG structure in the river. Our findings provided more understanding and insights into the functional structure of EPT in relation to agricultural pollution and can contribute to developing trait-based biomonitoring tools in Africa.Keywords: agricultural pollutionfunctional organisationmacroinvertebrate biomonitoring

AbstractActinomycetota are bacteria with biotechnological potential known to produce bioactive compounds in their natural ecosystems. Natural ecosystems include extreme environments such as soda lakes. Lake Natron is one of the soda lakes found in Arusha region, Tanzania. This study aimed to characterise and establish the phylogenetic diversity of the isolated Actinomycetota species that inhabit the lake waters. Results after 16S rRNA gene sequencing showed eleven genera of phylum Actinomycetota: Streptomyces, Micrococcus, Microbacterium, Gordonia, Micromonospora, Kocuria, Isoptericola, Dietzia, Arthrobacter, Nocardiopsis and Mycobacterium have been identified. Of these, Streptomyces radiopugnans, Streptomyces harenosi, Streptomyces althioticus, Micrococcus terreus and Kocuria sp. are reported for the first time in this soda lake, and this is the first time that Gordonia sp. has been reported from a soda lake in East Africa. Micromonospora sp. and Arthrobacter sp. are reported for the first time as occurring in a Tanzanian soda lake and three putative new species of Actinomycetota have been revealed. The Actinomycetota species described in this study sets a platform for future bioprospection of novel bioactive compounds from Lake Natron.Keywords: extreme environmentsbioprospectinggene sequencingrift valley lakessoda lakes16S rRNA

AbstractAnthropogenic activities have put tremendous pressure on the natural condition of wetlands. However, few studies have used indices based on benthic invertebrates to assess the effect of these pressures on wetland ecosystems. Multi-metric indices (MMIs) have been used successfully to assess freshwater ecosystems worldwide and are an important management tool, but little is known about their applicability in the wetlands of Ethiopia. In this study, we developed MMIs for wetland invertebrates to assess wetlands in Ethiopia. The wetland invertebrate assemblages were sampled from 24 sampling stations in six wetlands in the Achefer flood plains. These sampling stations included those in least affected areas and those affected by adjacent, agricultural and urban activities. Forty-one candidate metrics were initially reviewed and screened before six core metrics were selected: Taxa richness, ET taxa richness, % EOT, % Diptera, % Collector/Filterer and % intolerant taxa. Mann–Whitney U tests, Box and Whisker plots, correlation analyses, and redundant metric tests were used to assess the ability of metrics to distinguish among reference and impaired wetlands. The MMIs were robust in discriminating reference wetlands from impaired wetlands and therefore have potential as a biomonitoring tool to assess the condition of, and to guide efforts to restore, freshwater wetlands.Keywords: anthropogenic disturbancebenthic invertebratesbioassessmentphysico-chemicalwetland condition

AbstractThe introduction of exotic species poses one of the greatest threats to biodiversity globally. Water hyacinth is a dangerous invasive species that has harmed Ethiopia's wetland ecology and economy. This research aims to evaluate the current distribution of water hyacinth and the impact of environmental variables on its spread, while also mapping future habitat suitability under climate change scenarios and assessing how these changes may influence the species' potential expansion. To estimate the risks of climate change to the species, a predictive model was developed from six modeling methodologies to investigate the climatic suitability of target species for the years 2050 and 2070 under two Representative Concentration Pathway (RCP) scenarios (RCP4.5 and RCP 8.5). Under the current climatic scenario, only 69.78% (789 503.8 km2) and 16.02% (181 262.8 km2) of the country is moderately and highly suitable for species dispersion and invasion respectively. The remaining 14.2% (160 620.9 km2) is unsuitable for the distribution and invasion of the species. In 2050, under the RCP4.5 and RCP 8.5, the 'highly suitable' range of water hyacinth is anticipated to expand by 16.35% and 15.39%, whereas the 'moderately suitable' area is predicted to increase by 70.81% and 71.52%, respectively. Under the RCP8.5 scenarios, compared to the current climatic conditions, in 2070 the 'highly suitable' region for the species is expected to increase by 11.48%. Its continuing growth would exacerbate the issue of ecological and economic crisis, cause significant economic and environmental harm and endanger the community's way of life. In order to avert or reduce these effects, a thorough examination of water hyacinth along the two RCPs by water resource scientists and mamangers, that takes into account how climate change is affecting water hyacinth growing locations in Ethiopia, and provides a proper solution, is mandatory.Keywords: Water hyacinthhabitat suitabilityspecies distribution modelshared socioeconomic pathwayinvasiveEthiopia
