Introduction Foodborne diseases that result from a wide range of illnesses caused by contaminated foods remain challenge in least-developed countries. The objective this study was to evaluate microbial quality and safety milk cottage cheese spatial distribution indicators foodborne pathogens along the dairy value chain three regions country. Methods A cross-sectional conducted December 2020 May 2021. total 912 samples were collected tested for aerobic plate count, coliform Escherichia coli Listeria monocytogenes , Salmonella enterica Campylobacter spp., according standard methods enumerations isolation procedures. Results Microbial found poor quality, as bacteria count estimated be 98% (95% CI 97.2–98.9%), 61.2% 58–64.3%), 28.6% 25.8–31.6%), respectively. load exceeded limits set Ethiopian Standards Agency. overall prevalence at least one pathogen 50.3% 47.1–53.7%), indicating raw collectors predominantly (OR = 2.1, p 0.003), followed processors 1.3, 0.003). Discussion analysis revealls standards concentrated central highlands Ethiopia, within nearly 100 kilometers radius Addis Ababa city surrounding towns.

Allometric Models for Estimating Biomass and Carbon Stocks in Natural and Homestead Highland Bamboo Stands in the Sidama Region, Ethiopia

Forests, Journal Year: 2025, Volume and Issue: 16(4), P. 701 - 701

Published: April 18, 2025

Highland bamboo (Oldeania alpina) plays a vital role in supporting local livelihoods, fostering biodiversity conservation and sustainable land management. Despite these benefits, its significant potential for carbon sequestration remains underutilized within Ethiopia’s climate mitigation strategies. In this study, we developed site-specific allometric equations to assess the biomass storage of highland bamboo. Data were collected from Garamba natural forest Hula homestead stands Sidama Regional State, Southern Ethiopia. on stand density structure gathered using systematically laid transects sample plots, while plant samples analyzed laboratory determine dry-to-fresh weight ratios. We models estimate aboveground (AGB) stock. The study results indicated that exhibited higher accumulation than stands. AGB was estimated at 92.3 Mg ha⁻1 118.3 stands, with total 52.1 66.7 ha⁻1, respectively. findings highlight both homesteads. Sustainable management integrating into farms can contribute change mitigation, support ecosystem restoration, enhance socio-economic development communities.

Biochar‐based fertilizers increase crop yields in acidic tropical soils

Biofuels Bioproducts and Biorefining, Journal Year: 2025, Volume and Issue: unknown

Published: May 1, 2025

Abstract Depletion of soil organic carbon and nutrients creates mounting challenges for agricultural production in tropical regions, putting livelihoods food security at risk. Biochar‐based fertilizer (BBF) has been suggested as a tool to maintain yields while concurrently improving content related functions. This study aims evaluate the effects different BBF formulations (biochar–digestate biochar–vermicompost) on yield wheat properties soils ranging from highly acidic near neutral pH mid‐ highlands Oromia Sidama regions Ethiopia. Our results showed that combining biochar with and/or inorganic fertilizers significantly increased above‐ground biomass dry grain soils. Application rates 20 t ha −1 yielded highest improvements, outperforming by enhancing up 94% 58%. Soil analyses revealed can increase pH, nutrient availability cation exchange capacity. Its effectiveness varied conditions, showing limited impact less soils, which supports its specific role mitigating acidity fertility deficiencies. Hence, is promising alternative amendment smallholder farms. Adoption into integrated management could reduce dependency imported fertilizers, promote circular bioeconomy contribute sequestration, making it viable option sustainable agriculture

Rainwater Harvesting Site Selection for Drought-Prone Areas in Somali and Borena Zones, Oromia Regional State, Ethiopia: A Geospatial and Multi-Criteria Decision Analysis

Water, Journal Year: 2024, Volume and Issue: 16(13), P. 1789 - 1789

Published: June 25, 2024

Rainwater collection systems play a crucial role in enhancing water availability regions with low precipitation. This study focused on identifying potential rainwater harvesting (RWH) locations drought-prone areas, specifically the Borena zone of Oromia and regional states Somali. research leveraged geospatial techniques multi-criteria decision analysis (MCDA) to assess feasible RWH sites. The dataset comprises essential factors such as rainfall, drainage density, slope, soil texture type, land use/land cover. These thematic layers serve inputs for analysis, each factor being weighted using Analytical Hierarchy Process (AHP) method based its significance. Reclassifying into subclasses facilitates suitability analysis. linear combination (WLC) technique is applied identify prioritize (PRWH) four classes: highly suitable, moderately suitability, unsuitable. Our findings reveal that 1% area, covering approximately 3288 km2, suitable RWH. Areas moderate constitute 12% (37,498 km2), while representing majority, encompass about 75% (242,170 km2). Additionally, 13% (41,000 km2) area deemed unsuitable proposed sites adaptable other low-precipitation regions. However, before implementing structures, further imperative. exploration socioeconomic variables future urged an in-depth examination various aspects environmental sustainability. paves way adapting align community needs life cycles also exploring socio-economic dimensions sustainability study. insights offer promising solutions address urgent issues associated scarcity. should include comprehensive site depictions, social economic activities, meticulous preparation cost-benefit

Transforming Urban Air Quality: Green Infrastructure Strategies for the Urban Centers of Ethiopia

Environmental Pollution, Journal Year: 2024, Volume and Issue: 363, P. 125244 - 125244

Published: Nov. 4, 2024

Urban green infrastructure (GI) plays a crucial role in improving air quality by removing pollutants and reducing emissions from structures. However, Ethiopia, inadequate GI planning, largely due to limited awareness among planners policymakers, can undermine the benefits of worsen urban issues. In this study, we demonstrate how strategy approach enhance assess negative impacts biogenic volatile organic compounds (BVOCs) emitted certain tree species using Hawassa as case study.
