​The GhanAqua project

​GhanAqua is a South-Driven, capacity building and research project funded by DANIDA and concerning the groundwater development for sustainable agriculture in Northen Ghana.


Searching for groundwater in Ghana
The Danish way to Groundwater all over the world

Kenya on globe Kenya   *

The Danish drinking water supply is 99% based on groundwater and Denmark has undertaken a major groundwater mapping to support sustainable groundwater exploitation. As part of this programme, 40% of the country has been investigated with airborne geophysics and the results used for geological and groundwater modelling. Now we are ready to share our approach and expertise with colleagues all over the world.

GEUS is currently participating in several international projects related to groundwater mapping. One of them is the GhanAqua project.

GhanAqua is a 5-year project funded by DANIDA. The project concerns the reprocessing of already existing airborne geophysical data (originally collected for mineral exploration purposes during former EU programs) to build reliable geological/hydrological models in the White Volta Basin in Ghana. In doing that, GhanAqua aims at:
  • strengthening research capacity in Ghana on hydrogeology;
  • developing an improved understanding of the groundwater resources in the White Volta Basin in Northern Ghana;
  • and quantitatively assessing the variations in groundwater budgets and the sustainability of groundwater abstraction for large scale irrigation development.

The project is conducted in close cooperation between scientific groups from both Denmark and Ghana. The Danish contribution include expertise within processing and interpretation of airborne geophysical data and hydro(geo)logical modeling. The Ghanaian scientists are contributing with local expertise on geology, hydrogeology and field investigations.
GhanAqua started on January 1, 2015 and will end on December 31, 2019. Look here for further reading about the DANIDA project in Ghana, GhanAqua
