Soil erosion is still a vector of environmental and economic concern affecting most parts the world, especially in Sub-Saharan African countries. Nevertheless, recent human activities hills, coupled with poor conservation measures practices, could have amplified rate at which soil lost southwestern highlands Ethiopia. This study focuses on quantifying prioritizing micro-watersheds that require actions by piloting spatial modeling loss upper Bilate watershed. Sentinel image, soil, DEM, rainfall, support practice data were used. A Revised Universal Loss Equation (RUSLE) using GIS satellite images was applied. The estimated average annual demonstrated to be 24.1 t ha−1yr−1 varied between 0.05 498.24 ha−1yr−1.

Eucalyptus camaldulensis is commonly planted on farmland in highland Ethiopia because of its high economic profitability. However, the expansion woodlot plantations has led to a decline crop growth and yield, which negatively affects food security. To address this issue, study aimed examine effects production security South Achefer. Data were collected from 180 respondents using three‐stage sampling technique for four kebeles district. The survey data analyzed descriptive inferential statistics, binary logit regression model SPSS software version 24. This found that most households (87%) perceived rapid increase expansion. allocation more land was positively significantly affected by family size, landholding total annual income, availability unproductive land. Additionally, revealed woodlots highly compete with nearly all grown crops nutrients moisture. causes reduction yield one quintals compared normal far tree. Approximately three‐fourths (71%) sampled farmers did not obtain stable annually considered insecure. alleviate insecurity, suggests stakeholders should focus improving livelihood alternatives rather than expanding woodlots.

Soil erosion and sediment yield driven by land use cover changes; pose severe threats to ecological sustainability, agricultural productivity, watershed health. This study evaluates soil in the Dumuga Watershed, Ethiopia, from 1993 2023, with a focus on impact of changes. Utilising time series Landsat data (TM, ETM+, OLI/TIRS), analyzes key factors influencing erosion, including rainfall erosivity, erodibility, slope steepness, management, conservation practice. The findings highlight dramatic shift use, cultivated increasing 62.3% (915.3 km2) 77.0% (1,132.0 forest declining sharply 13.3% (196.0 3.8% (56.2 km2). transformation has exacerbated maximum loss rising 726.7 tons/ha/year 937.8 2023. area classified under very increased 41.0% 54.1%, directly correlating rise yield. These underscore urgent need for targeted strategies mitigate enhance retention, restore balance. Therefore, implementing integrated management approaches is essential safeguarding watershed's long-term productivity resilience.

The cycle of food insecurity caused by poor water management practices poses major concerns for the sustainability living balance in Southwestern Ethiopia's smallholder agricultural areas. prior study looked at crop land suitability assessments. However, there are still knowledge gaps on irrigation infrastructure sites. As a result, this research was launched to evaluate surface (SWI) potential river watersheds Gomma area, southwestern Ethiopia. To identify possible SWI, biophysical parameters such as topography, stream order, soil texture, use-land cover, drainage density, and climate elements were analyzed. Potential SWI sites identified using multiple-criteria decision-making analysis from sources information reviewed, which applied selecting suitable A comparison matrix, weighted analysis, Boolean-operations, survey approaches. findings reveal that about 16% is highly (S1) drip or sprinkler schemes, while 7% 77% total fall under categories moderate unsuitable respectively.

The editors have decided to retract this article for the following reasons: authors classified land suitability related rainfall as follows: “Previous study by Abubakar et al. (2023b) into four classes: (1329–1420mm), (1420–1490mm), (1490–1560mm) and (>1560mm) categorizes highly suitable, moderately marginally suitable not respectively oil palm tree cultivation”. In literature (including cited ), however, order is reversed. Ideally, requires >2000mm of well-distributed per year. lower class still entirely unsuitable, but there will be a very strong seasonality in production yields large. As misinterpretation affected their entire analysis, been asked revise accordingly. meantime, an expression concern was published. two successive revised versions received, changed only few paragraphs (about rainfall...), they did re-run analysis accordingly, nor change assessment at all, leading same conclusion before despite reversed precipitation assumptions.
