E. coli in tropical swamps: decay or regrowth ? EC2CO NARIBACT project

Fecal contamination in surface water is a major health concern in developing countries. The objective of the EC2CO NARIBACT project (2019-2020), led by Laurie BOITHIAS (Phys.-adj. CNAP, GET), is to better understand the drivers of the bacterial dissemination in tropical areas.

In August 2019, Laurie BOITHIAS, together with Olivier RIBOLZI (IRD, GET), Norbert SILVERA (IRD, iEES Paris), Paty NAKHLE (PhD student at GET), Anne PANDO (IRD, iEES Paris), and the 4 local assistants assessed the potential decay and/or regrowth of E. coli in a swamp in Northern Laos.

Geophysical measurement campaign in India

A geophysical measurement campaign to characterize the spatial heterogeneity of the regolith thickness (main potential water stock in fractured aquifers) was carried out in May 2022 in both the Berambadi and the Mule Hole catchments (PI: Jean Riotte, IRD). Supported by EQUIPEX CRITEX, the campaign combined electrical resistivity, seismic, and Control Source Audio-Magneto-Telluric (CS-AMT) surveys. […]

Nutrients’ cycles and budget: the first mission to dig and instrument deep pits in Berambadi catchment, India, was held in June-July 2022 within the ANR NUTRILIFT project (PI: Jean Riotte, IRD). These pits are located in both an irrigated plot and an agroforestry plot. They are 9 and 10 m deep, respectively, and their diameter […]


Field campaign in Cameroon to study biogeochemical cycles and weathering in a tropical context

On September 19-25, Jean Riotte, Christelle Lagane, and Jean-Jacques Braun from GET/IRD participated to a field campaign at the Nsimi experimental watershed, monitored within the M-TROPICS CZO. Recently, the land use in Nsimi watershed has been changed to agriculture mixed with residual forest and fallow. The objective of the mission was thus to start the […]
