Amplified Local Cooling Potential of Forestation in Eastern Ethiopia’s Arid Lowlands under Climate Change: Insights from Dire Dawa, Shinile, and Somali Regions

Belay Sitotaw Goshu — 2025-11-07

This study investigates the biophysical cooling effects of forestation in eastern Ethiopia’s arid lowlands, Dire Dawa, Shinile, and Somali regions, amid climate warming, using satellite-derived data (MODIS, ERA5-Land) from 2003–2023 and CMIP6 projections to 2080 under SSP2-4.5 and SSP5-8.5 scenarios. Pairwise comparisons of land surface temperature (LST), evapotranspiration (ET), and albedo between forested and open lands (grassland, cropland, shrubland) revealed a mean cooling effect of 3.5–4.0 °C, driven primarily by enhanced ET (1,250–1,350 mm/year in dry seasons) offsetting albedo-induced warming (+18–24 W/m²). Seasonal dynamics showed amplification during dry periods (up to 4.5 °C), with Theil-Sen trends indicating a 0.14–0.18 °C/decade increase in cooling, linked to soil moisture declines (-0.004 m³/m³/decade). Structural equation modeling confirmed ET’s dominance (β=0.72 for ΔLST), though albedo’s role rises to 40% by 2080 under high emissions due to stomatal closure reducing ET by 15–20%. Projections forecast sustained amplification (4.2–4.7 °C) under moderate scenarios with 15% tree cover increase, but diminution (3.2–3.7 °C) under high emissions. Spatial analysis highlighted groundwater-dependent efficacy, strongest in Somali’s rangelands. Findings underscore forestation’s potential for heat mitigation, supporting initiatives like Ethiopia’s Green Legacy and Right Tree in the Right Place projects, while emphasizing adaptive strategies to balance water competition and albedo effects for climate-resilient land management.

Geomorphological, Electrical Resistivity and Magnetic Methods for Assessing Groundwater Potential in Adet Town, West Gojam, Ethiopia

Krubel Molla — 2025-11-10

Imagine the sun-scorched fields of Adet Town, West Gojam, and Ethiopia, where families rise each day with a flicker of hope, their hands calloused from carrying water across cracked earth. This study, "Geomorphological, Electrical Resistivity and Magnetic Methods for Assessing Groundwater Potential," breathes life into their dreams, weaving a heartfelt narrative through science to uncover hidden aquifers beneath volcanic plains. Guided by the Amhara National Regional State Water Irrigation and Energy Office Bureau (ANRSWIEOB), we walked the land, 50-meter traverses marking our steps, mapping magnetic fields that dance from 33,900 to 37,400 nT, resistivity layers hinting at low-conductivity zones, and geomorphic contours revealing a 644-meter eastward drop shaped by ancient floods. The findings are a beacon of resilience: magnetic anomalies, like those at PpW3 and Shena, signal fractured basalt where water might pool, with variability (σ up to 3,120 nT) reflecting tectonic gifts and challenges, dry wells a stark lesson from Tali Spring. Resistivity profiles illuminate perched aquifers, while Nile-like escarpments guide us to faulted recharge paths, echoing Adet’s rugged terrain. Statistically, slopes (-1.1 nT/m) and ranges (3,500 nT in BH BRIG) highlight deep structures, promising yields yet demanding care to avoid depletion, as seen in Lake Tana’s decline. Humanly, it’s a story of community, elders sharing spring lore, children dreaming of wells, scientists blending past wisdom with modern tools. The results reveal hope amid scarcity, urging sustainable stewardship. The land speaks, and we listen, turning geophysical whispers into flowing lifelines for Adet’s people, a testament to humanity’s enduring bond with the earth.

Mathematical Modeling and Optimization of the Anomalous Hall Angle in Magnetic Topological Semimetals

Belay Sitotaw Goshu — 2025-11-10

Magnetic topological semimetals like Co3Sn2S2 exhibit a large anomalous Hall angle (θA), making them promising for magnetic sensors and spin-orbit torque (SOT) devices, but scalable synthesis and real-time control remain challenging. This study aimed to predict and optimize θA in Co3Sn2S2, focusing on scalable thin-film deposition and dynamic modulation for enhanced device applicability. A predictive model (θA = arctan(σxy/σxx)) was validated against experimental data (RMSE = 10.59°), followed by simulations of thin-film deposition (substrate temperature: 200–600°C, deposition rate: 0.1–2.0 Å/s) and dynamic modulation (strain: -2% to 2%, electric field: 0–0.5 V/nm). The model accurately predicted θA for Fe-doped Co3Sn2S2 (25.6° vs. 24.8° experimental) but overestimated TbPdBi (error: 10.8°). Thin-film deposition at 208°C and 0.1 Å/s yielded θA = 7.2° (σxy = 528 Ω⁻¹ cm⁻¹, ρxx = 239 μΩ cm), below experimental benchmarks (24.8°). Dynamic modulation at strain = 1.8% and electric field = 0.50 V/nm achieved θA = 7.6° (σxy = 1155 Ω⁻¹ cm⁻¹, ρxx = 115 μΩ cm), suitable for basic sensors but insufficient for SOT devices (θA > 20°). While the framework captures θA trends, current synthesis and modulation methods yield θA values below device requirements, necessitating improvements. Higher deposition temperatures (500°C–600°C), stronger modulation (strain > 3%, electric field > 1.0 V/nm), and advanced modeling (e.g., DFT-derived Berry curvature) are recommended to achieve θA > 15°, enabling practical AHE applications.
