Abstract: One of the most vital natural resources for a nation's growth and development is groundwater, which is stored in the void spaces of the geological strata beneath the Earth's surface. However, due to the nature of groundwater, determining the groundwater potential zone remains a challenging task. The objective of this study is to identify groundwater potential zones in Chagni using timely and economical Geographic Information System (GIS) and remote sensing techniques. For groundwater potential zonation, nine thematic layers derived from the Digital Elevation Model (DEM) with 12.5m spatial resolution, Sentinel-2A satellite images of the year 2022, and other secondary sources were utilized in this research. Using the MCDA of the AHP method, all of the thematic layers (slope, rainfall, drainage density, lineament density, geomorphology, lithology, soil, land use/land cover, and groundwater depth) were reclassified, and a weight for each factor was assigned based on their relative contribution to groundwater with the help of experts’ knowledge. The resulting map of groundwater potential zones was identified by using weighted linear combination (WLC) in ArcGIS and shows 16% and 30% of the area have very high and high potential, respectively, while 10% of the area has very low potential. In general, the assessment of groundwater potential requires further geotechnical and hydrological analyses to ensure the suitability with the required standards for design and implementation.

Abstract: Ethiopia’s strong dependence on climate-sensitive sectors, combined with limited adaptive capacity, makes climate change one of the most significant threats to the country’s socioeconomic development. This review synthesizes current knowledge on observed climate trends, future climate projections, and the diverse impacts of climate change across Ethiopia’s regions and key sectors. Evidence consistently indicates rising temperatures, increasing rainfall variability, and a growing frequency and intensity of extreme events such as droughts and floods. These changes profoundly affect agriculture and food security, water resources and hydropower generation, pastoral livelihoods, human health, ecosystems, and rapidly expanding urban systems. Marked regional differences are evident: highland areas face soil degradation, shifting agroecological zones, and declining crop productivity, while lowland and pastoral regions experience increasing aridity, rangeland degradation, and livelihood insecurity. The review further examines cross-cutting issues, including gendered vulnerability, technological innovation, economic impacts, migration, and climate finance, highlighting the interconnected nature of climate risks. National policy frameworks, governance mechanisms, and documented case studies illustrate pathways for enhancing resilience, while also revealing persistent implementation and capacity gaps. Key research priorities include the need for high-resolution climate projections, long-term monitoring of climate impacts, and improved understanding of urban climate risks. Strengthening institutional capacity, scaling up climate-smart practices, and enhancing international cooperation are essential to support Ethiopia’s transition toward climate-resilient and sustainable development.
