In recent years, armed conflicts are globally on the rise, causing drastic human and environmental harm. The Tigray war in Ethiopia is one of violent that has abruptly reversed decades ecosystem restoration efforts. This paper analyzes changes woody vegetation cover during period conflict (2020–2022) using remote sensing techniques, supplemented by field testimony secondary data. Extent was analyzed Normalized Difference Vegetation Index (NDVI) thresholding method from Sentinel 2 images...
Contamination of water resources by heavy metals causes health problems for humans. This study attempts to investigate the metal contamination levels, risks and sources appraisal groundwater surface in mountain-bounded catchment low-grade basement rock-dominated area the Irob, Tigray. Eighteen grab samples (13 borehole water, 2 spring 3 water) were collected analyzed pH, electrical conductivity, total dissolved solids using standard procedures. The findings contrasted with those standards...
Abstract The primary source of drinking water in Ethiopia's semi-arid mountainous regions is groundwater. present study aims to assess the hydrogeochemical characteristics low-grade basement rocks dominated by catchments. Moreover, it examines suitability groundwater quality for purposes Irob, Tigray, northern Ethiopia. However, relatively little known about chemistry and resources area. Fifteen samples were collected examined ions according standard procedures. outcomes assessed against...
ABSTRACT Irrigation alleviates poverty in arid and semi-arid regions, such as Ethiopia, necessitating a water suitability assessment. This study evaluates irrigation quality the Irob catchment, Northern Ethiopia. It differs by using combined parameters of index (IWQI) for comprehensive assessment beyond standard comparisons. Eighteen samples were collected analyzed ultraviolet spectrometry, titration, atomic absorption spectrometry. The evaluation included salinity, total dissolved solids...
The paper presents the environmental impact of artisanal gold mining activities on waters and sediments around Meli, northwestern Tigray, Ethiopia. Stream sediment, water, tailing samples were collected in dry season January 2019 analyzed for heavy metals Cu, Zn, Pb, As. physicochemical parameters (pH, EC, major cations, anions) a few water also measured. Flame atomic absorption spectrometry was used to determine level stream sediments. results show that has highest concentration followed by...
The rapid economic growth and urbanization in Ethiopia have led to extensive construction activities major cities. Construction known generate large quantities of wastes that pose serious environmental problems. This paper presents the challenges waste management practices Mekelle city explores appropriate measures address issues a more sustainable way. Field observation, questionnaire survey, interviewing public sector officials at different levels was conducted identify source options...
<h3>ABSTRACT</h3> Immunization programs reach more children and communities than any other health intervention, thus making immunization a promising platform for integrating essential services. There is dearth of literature on nutrition interventions, such as infant young child feeding (IYCF) counseling iron-folic acid (IFA) supplementation, into routine To address this evidence gap, 15-month pilot study (August 2019 to November 2020) tested the feasibility IYCF IFA supplement distribution...
The Reaching Every District (RED) strategy, implemented in Ethiopia for over 15 years, has helped to improve immunization performance. However, recent demographic and health survey data indicate wide variations coverage. To address these disparities, quality improvement (QI) tools methods were applied phases the RED strategy between 2011 2018 ultimately scaled 103 districts Ethiopia. Quantitative qualitative collected from 2015-2018 examine RED-QI uptake, practices, sustainability, effects...
