Although Ethiopia is one of the world's fastest-growing economies, access to sustainable energy and cutting-edge clean technology remains a major concern. The government making significant efforts generate renewable provide more its citizens. Despite this, traditional fuels (charcoal, fuel wood, dung cakes, agricultural waste) account for around 87 percent Ethiopia's use, they pose range health environmental risks. Solar, hydro, wind, geothermal resources abound in nation, but only 5% country's total hydroelectric capacity being used; while, rest either underutilized or underdeveloped. An in-depth look at potential, as well opportunities problems it faces, presented this review. With combined installed over 7000 MW, hydropower wind power are most promising sources yet. It hoped that assessment will shed light on how can harness maximize use abundant sources.

Depletion of soil fertility in tropical regions is a pressing concern contributing to lower crop yields. This study aimed evaluate the effects biochar and co-composted on acidic growth performance teff (Eragrotis (Zucc.)) sub-tropical highlands Ethiopia. Co-composted was produced by mixing Acacia decurrens with chicken litter cow dung manure at different ratios 100:0:0, 25:75:0, 15:85:0, 25:0:75. Treatment impact properties yields were evaluated applications 0, 5, 10, 20 t ha–1 field trials.

Acacia decurrens (hereafter Acacia) agroforestry system has been expanding rapidly in the northwestern highlands of Ethiopia. The provides multiple eco-environmental services; however, there is inadequate quantitative evidence on its livelihood benefits. This study, therefore, investigated benefits and challenges Acacia-based Awi area, Northwest Data was collected through household survey quetionnaires (296 randomly selected growers), focused-group discussions, interviews, observations. A combination qualitative methods used for data analysis. findings showed that crop production, charcoal making, animal rearing, fuelwood selling were major sources livelihood. Notwithstanding complex (Acacia pests/diseases, traditional charcoal-making, limited road access market opportunities, negative human-health impacts, high production cost), positively affected farmers livelihoods. Comparatively, natural, physical, financial, human social capital indices higher by 0.25, 0.24, 0.43, 0.06, respectively, post-than pre-Acacia periods. overall index increased from 0.47 (pre-Acacia) to 0.71 post-Acacia period. study concluded this practice immense benefits, although diverse question sustainability. Therefore, short long-term strategies should be designed strengthen opportunities address challenges.

The study involved a survey 36 paired production kiln sites adjacent reference 18 croplands to analyse physicochemical tef ( Eragrostis ), barley Hordeum vulgare ) wheat Triticum aestivum ). A was undertaken investigate seed germination chemical fertilizer needs at sites. Local farmers interviewed for their perceptions management practices. short‐term presence significantly increased sand fraction, pH, organic carbon, available phosphorous, exchangeable Mg 2+ K + compared Charcoal practice raised pH by 0.83 units, P 40%, 92% 303%, respectively. Exchangeable acidity Al 3+ lowered over 80% Both aboveground biomass grain yield tef, were, on average, 135% higher than Furthermore, crops grown taller had greener larger leaves. Farmers' responses indicated reduced inorganic application Results from provided evidence faster germination, enhanced charcoal‐treated soils. suggests that inclusion remnants heating can increase carbon storage, improve which promote reduce need degraded, agricultural soil.

In the northwestern Highlands of Ethiopia, a region characterized by diverse ecosystems, significant land use and cover (LULC) changes have occurred due to combination environmental fragility human pressures. The implications these for ecosystem service values remain underexplored. This study quantifies impact LULC changes, with an emphasis on expansion plantation forests, in monetary terms promote sustainable management practices. Using Landsat images Random Forest algorithm R, patterns from 1985 2020 were analyzed, estimated using locally adapted coefficients. classification demonstrated high accuracy, 0.97, 0.98, 0.96, 0.97 maps 1985, 2000, 2015, 2020, respectively. Croplands consistently dominated landscape, accounting 53.66% area peaking at 67.35% then declining 52.86% 2020. Grasslands, initially second-largest category, significantly decreased, while wetlands diminished 14.38% 1.87% Conversely, particularly Acacia decurrens, expanded 0.4% 2000 28.13% becoming type. total value district declined USD 219.52 million 39.23 primarily wetland degradation.

Several Acacia species are aggressive invaders outside their native range, often occupying extensive areas. Traditional management approaches have proven to be ineffective and economically unfeasible, especially when dealing with large infestations. Here, we explain a different approach complement traditional by using the waste from activities. This can provide stakeholders tools potentially reduce costs encourage proactive actions. It also prioritizes potential applications of biomass for agriculture forestry as way sequestering carbon released during control We advocate use compost/vermicompost, green manure charcoal produced waste, several studies shown effectiveness in improving soil fertility supporting crop growth. The derivatives bioherbicides or biostimulants is pending validation under field conditions. Although invasive spp. banned commercialization cultivation, remains permissible. In this respect, recommend collection vegetative stage its subsequent after being dried dead, prevent further propagation. Moreover, it crucial establish legal framework mitigate risks associated handling disposal waste.
