He holds an MSc in Hydrogeology and a BSc in Applied Geology from Mekelle University, and he is an Accredited Water Resources Professional Certificate holder, registered as a Practicing Professional Hydrogeologist by the Tigray State Water Resources Development Bureau. Afeworki has served as Earth Science Case Team Manager and Senior Hydrogeologist at Tigrai Water Works Study, Design and Supervision Enterprise, and previously worked as Senior Hydrogeologist with Tekeze Deep Water Wells Drilling, Supervising Hydrogeologist with Tigrai Water Works Construction Enterprise, and Hydrogeologist and district water resources office head in Hawzen. His professional work includes planning, implementation, monitoring, and evaluation of groundwater development projects, deep well drilling, well construction, pumping tests, WASH projects, water supply systems, irrigation water supply schemes, water harvesting schemes, dam foundation investigations, and technical supervision of multidisciplinary Earth Science teams. His technical expertise includes hydrogeological and geophysical investigations, groundwater potential zone mapping, borehole logging, pumping test interpretation, feasibility and detailed study reporting, ToR preparation, drilling contract management, geotechnical investigation of dam foundations, and design support for water supply infrastructure. He has extensive practical experience applying GIS and remote sensing for groundwater exploration, water resources development, terrain analysis, geological and hydrogeological mapping, land use and land cover mapping, drought analysis, flood inundation mapping, vulnerability assessment, hazard analysis, environmental monitoring, sustainable land management, agricultural monitoring, and disaster risk management. Afeworki also brings advanced skills in data science, machine learning, geospatial analytics, Earth Observation, radar remote sensing, hyperspectral data, climate data interpretation, and environmental intelligence. His training portfolio includes certificates from institutions and platforms such as ESA, ESRI, Cap-Net UNDP, UNEP, NASA ARSET, University of Geneva, Stanford, University of Toronto, UC Davis, Johns Hopkins University, IHE Delft, and ECMWF. His recent research and conference work covers climate aridity dynamics, NDVI vegetation trends, water deficit index prediction using remote sensing and machine learning, groundwater potential mapping, and GIS and remote sensing applications for groundwater exploration. His profile is highly relevant for groundwater development, climate-resilient water management, WASH programming, remote sensing-based water resources assessment, and sustainable development projects in Ethiopia, Africa, and international contexts.
