New field experiments assessing groundwater storage in the Iullemmeden Basin (Niger/Nigeria)

re-posted from GroFutures

New field experiments assessing groundwater storage in the Iullemmeden Basin have recently been completed under GroFutures by a team of early career researchers. From December 2018 to January 2019, Fabrice Lawson from the Université d’Abomey Calavi and IRD in Benin (UAC/IRD), and Jean-Baptist Gnonhoue (IRD, Benin) worked with colleagues, Rabilou Mahaman and Boukari Issoufou from the Université Abdou Moumouni of Niamey (UAMN) in Niger to conduct field experiments applying Magnetic Resonance Sounding (MRS) and Time Domain Electromagnetics (TDEM), to generate in-situ measurements of groundwater storage. Such measurements of groundwater storage are rare despite their fundamental importance to understanding quantitatively the availability and sustainability of groundwater resources.

In total, the team conducted experiments at 26 sites, including 13 in the Dallol-Maouri region in central Niger and 13 in the Goulbi-Maradi region in southeastern Niger, just north of the border with Nigeria. Fabrice and Jean-Baptist led this field research sharing their expertise with their counterparts in Niger. Fabrice and Jean-Baptist (an early career scientist and engineer, respectively) developed their expertise to apply these sophisticated instruments under the tutelage of Jean-Michel Vouillamoz of IRD based at the University of Grenoble, France. The team was also supported by the lead GroFuturesresearchers in the Iullemmeden Basin Observatory, Professor Yahaya Nazoumou at UAMN and Dr. Guillaume Favreau of IRD, Niamey.

Results from field experiments and the subsequent processing and analyses of data will inform not only evaluations of available groundwater resources in these regions of the Iullemmeden Basin but also stress-testing of groundwater development pathways, developed by stakeholders, through numerical modelling. Well done to Fabrice, Jean-Baptist, Rabilou and Boukari!

  • Information collected through physical and social science methods was shared and discussed at the GroFutures Annual Workshop in Niger, with partners in and outside the study.
  • Open-source modelling software under FREEWAT platform was successfully piloted for ‘stress testing’ the sustainability of Groundwater Development Pathways accounting for climate and land-use change.
  • New water monitoring has been established to help manage the Iullemmeden Basin, which is shared by Niger and Nigeria

Grofutures launch in transboundary Iullemmeden basin

re-blogged from GroFutures

GroFutures was launched in the transboundary Iullemmeden Basin at a workshop held at Abdou Moumouni University (UAM) of Niamey in Niger on 23rd August 2016. The workshop was opened by the Vice Chancellor, Hon. Professor Amadou Boureima, and welcomed by the Director General of Water Resources in the Ministry of Hydraulics and Sanitation of Niger, Mr. Abdou Moumouni Moussa; Engineer Koné Soungalo representing the Niger Basin Authority; Dr. Oumarou Malam Issa, Country Representative of IRD in Niger; and the Deans of Faculties of Sciences and Agronomy (UAM).
