Hydrogeological and hydrochemical mapping of Ethiopia

The Geological Survey of Ethiopia and the Czech company GEOtest a.s. have signed a Memorandum of understanding regarding the implementation of a significant project “Hydrogeological and hydrochemical mapping - Completion of hydrogeological mapping in Ethiopia” which will be performed within the framework of Development Cooperation between the Czech Republic and the Federal Democratic Republic of Ethiopia. The project is funded by the Czech Government via Czech Development Agency. The local partner organization is Geological Survey of Ethiopia (GSE).

The objective of the project “Hydrogeological and hydrochemical mapping”, which started in June 2015 and will be finished in November 2019, is to contribute to the fulfillment of Sustainable Development Goal SDG 6 in Ethiopia: Ensure availability and sustainable management of water and sanitation for all. Mapping and assessment of groundwater resources for the purpose of water supply and irrigation are fundamental for further development of the country.

The project comprises of compilation of hydrogeological and hydrochemical maps including explanatory notes at a scale of 1 : 250 000, publication of all hydrogeological outputs at the GSE website and their further dissemination to all Regions of the country and to all potential users. The project also aims at building the capacities of Ethiopian experts in the field of research and assessment of groundwater sources, compilation of hydrogeological and hydrochemical maps at various scales and their practical interpretation.

The final output of the project is that Ethiopia will be completely covered by hydrogeological maps at a scale of 1 : 250 000 by 2019. To achieve this output it is still necessary to complete hydrogeological and hydrochemical mapping of 37 map sheets of various parts of Ethiopia. In addition, unification of these new maps with maps which have been already compiled by GSE will be done in a format suitable for on line presentation.

Mapping of groundwater resources in a form hydrogeological maps accompanied by explanatory notes has been carried out by GSE since early 80s (with Mekele being the first sheet published) and has accelerated over the past 10 years. From the beginning the Czech Republic has been supporting the mapping activities of GSE using a scheme where the participation of Czech experts has been financed by the Czech Government via Czech Development Agency within the framework of the Czech Republic Development Cooperation Programme. Participation of Ethiopian professionals has been financed by the Ethiopian Government.
