Methane from Cattle and Its Direct and Indirect Impacts on Human Health: Implications for Cancer and Community Exposure

Authors: Belay Sitotaw Goshu*

Abstract: This comprehensive analysis examines the complex relationships between agricultural methane emissions, air quality degradation, and cancer risk, revealing significant public health implications. While methane itself is not directly carcinogenic, it serves as a critical precursor to tropospheric ozone and particulate matter (PM2.5), both established carcinogens. The findings demonstrate that livestock operations contribute substantially to global methane emissions, with beef and dairy cattle accounting for 4,700 million tons CO₂eq annually. Methane reduction strategies show variable effectiveness (15-40% mitigation potential), yet emissions continue to rise due to production intensification, creating a concerning implementation gap.

Propagation Anomalies in Altitudinal Refractivity Gradients: Meteorological Drivers in, Ethiopia's Dire Dawa Region

Authors: Belay Sitotaw Goshu*

Abstract: This study investigates tropospheric radio refractivity and propagation anomalies across an altitudinal transect in Dire Dawa, eastern, ethiopia (1200-2100 m ASL), using hourly meteorological data from three stations (A: airport, B: foothills, C: plateau) over 2022-2023. Refractivity (N-units) exhibits exponential decay with elevation (r2 = 0.99), averaging 311.58 (SD = 18.25) at A, 279.06 (18.18) at B, and 246.65 (16.52) at C. Vertical gradients confirm terrain amplification: A-B mean -81.31 N-units/km (SD = 40.03), exceeding ITU-R standard (-39), with B-C -64.81 (24.41) and A-C -72.15 (17.24).

Sustainable Use of Nature Resources and Agriculture High-Quality Development

Authors: Zhongsheng Guo

Abstract: As economy develops and population increase, there is an increasing demand for plant goods such as timber, food, medicine and so on and ecological service such as clean air, fresh water and environment. Because plant goods and service producing by original forest cannot meet the increasing need of people, most of the original forest has gradually become fruit, farmland, plantation and grass. A lot of exotic plant was introduced to produce special production and service in the plant restoration. As introduced plant grow, soil and vegetation degradation and crop failure will happen because plant overload and overuse nature resources or plant waste resources because plant underuse nature resources because underload.
