Municipal solid waste management (MSWM) in Ethiopia is a complex issue with institutional, social, political, environmental, and economic dimensions, impacting sustainable development. Effective MSWM planning necessitates understanding the generation rate composition of waste. This systematic review synthesizes qualitative quantitative data from various sources to aggregate current knowledge, identify gaps, provide comprehensive municipal Ethiopia. The findings reveal that 0.38 kg/ca/day, being predominantly food waste, followed by ash, dust, sand, yard Over 85% this MSW either reusable or recyclable, significant portion organic matter (73.13% biodegradable) 11.78% recyclable materials. Physicochemical analyses Ethiopian suitable for composting biogas production, offering opportunities reduce environmental pollution, GHGs, support urban agriculture, create job opportunities. However; challenges persist, including lack political will, weak planning, limited community awareness, inadequate infrastructure, only 31.8% collected legally, leading inefficient harmful disposal practices. To improve MSWM, should focus on public awareness; increased funding, infrastructure investment, private sector partnerships, implementing 4 R principles (reduce, reuse, recycle). An integrated approach involving government, industry, civil society essential. Further research physicochemical properties strategic uses needed enhance

Effects of proximity of the sediment mining pit on riverbank stability

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Март 26, 2025

Unregulated sediment dredging near riverbanks considerably increases the risk of bank failures. This study examines how proximity mining pits influences riverbank stability by conducting controlled laboratory flume experiments on three slopes: 25°, 31°, and 40°. The analysis considers scenarios—upstream pit, instream no-pit conditions while evaluating key hydraulic parameters, including mean streamwise velocity, Reynolds shear stress (RSS), turbulent kinetic energy (TKE). These measurements provide insights into flow dynamics, turbulence characteristics, morphological changes. results indicate that steeper slopes experience higher erosion risks. 40° slope exhibits velocity up to 35% TKE peaks reaching 40% above baseline levels when a pit is in close proximity, leading severe toe scouring detachment. In contrast, 25° maintains equilibrium, limiting 15% experiencing minimal turbulence-induced erosion, making it most stable configuration for reducing mining-related impacts. 31° slope, corresponding angle repose, strikes balance between mobility but requires localized reinforcements mitigate erosion. findings highlight need well-regulated practices targeted stabilization strategies reduce growing
