2022 long-term missions in Lao PDR

After almost three years of travel restrictions in Lao PDR, Olivier Ribolzi (IRD GET), Henri Robain (IRD iEES Paris), and Laurie Boithias (CNAP GET) could go to both Vientiane and Luang Prabang for a 2-month stay funded by IRD. With Norbert Silvera (IRD iEES Paris), their work there was mostly focused on the processing and […]

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. […]

Launching ANR NUTRILIFT project

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 […]

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, […]

‘Soil Bag’ experiment ended in M-TROPICS/MSEC site in Laos

The “Soil Bag” soil column incubation experiment on the M-TROPICS/MSEC site in Laos, under teak tree plantation, was ended during the week of June 3, 2019. The global challenges of this experiment is to address the role of soil engineers on soil quality, conservation, and rehabilitation, under different environmental constraints. It also aims to provide […]

Field survey in Huay Ma Nay catchment, Thailand, for building land use map

Jean-Louis Janeau (IRD-iEES Paris) and Nitjaporn Koonklang (IRD assistant) were in the field during the first week of May to survey the land use in Huay Ma Nay catchment, Phrae Province, Thailand. They described the soil surface features of more than 300 measurement points in this hilly catchment with steep slopes, mostly covered by maize […]
