As a transverse action within the OZCAR research infrastructure, IGE organized a workshop on particulate fluxes measurement and monitoring within the critical zone. The long term monitoring of soil erosion, suspended sediments and bedload performed by M-TROPICS was presented, together with related research on land use change impact, river water… Continue Reading
Scientists from the USTH and from the Thuyloi University visited the monitored catchment of Dong Cao, northern Vietnam (M-TROPICS/MSEC). The visit was led by Rinh Pham Dinh (SFRI) and by Jean-Luc Maeght (IRD, iEES-Paris). Visiting scientists discovered the history of the research carried out on this peri-urban watershed (49.7 ha).
Christian Valentin (IRD) coordinated a series of 6 books at ISTE Editions about the role of soils within the critical zone, including in the tropics. Renewed interest for soils is due to the social challenges they are associated to: agricultural productions, climate and biogeochemical cycles regulation, urbanization… By locating soils… Continue Reading
Lancelot Pinta defended a master degree (M2) thesis entitled “Impact of rainfall erosivity and land cover change on total organic carbon accumulation in sediments of a water reservoir in Thailand” on Thursday June 28th at Sorbonne Université (Paris). The objectives of this study were to determine, the amount of catchment-derived… Continue Reading
Floriann Langlet, a master student from the Université de Toulouse III Paul Sabatier, just finished his internship at GET laboratory. He analyzed the occurrence of bacterial pathogens along the Mekong river basin (M-TROPICS/MSEC) and found that soil type, discharge, and turbidity were among the key variables associated to E. coli… Continue Reading
Jean Riotte (IRD-GET) and Laurent Ruiz (INRA/IRD-GET), together with M. Tripti (Post doc IISc) and Nils Dubois (M2 ISTOM), performed a field experiment within the frame of the ANR ATCHA project, aiming at assessing the fate of nitrates from irrigation by groundwater. The experiment was performed in the Berambadi catchment (M-TROPICS/BVET)… Continue Reading
A poster was presented at EGU 2018 Conference by Dr. Kyung Hwa Cho, from UNIST, South Korea, about the modelling of E. coli in Houay Pano catchment (M-TROPICS/MSEC): a research work led by Minjeong Kim in collaboration with GET. The abstract is available here.
A book authored by Yves AUDA has been published, handling the analysis of the critical zone with open-source softwares GRASS and QGIS: field sampling, hydrological models, landscape analysis, remote sensing mapping, digital elevation models, etc. Theory and exercises are based on data from the M-TROPICS/MSEC CZO in Northern Laos, gathered… Continue Reading
This PhD proposal aims at better understanding the transport and fate of pathogen bacteria in tropical areas, e.g. fecal pathogens such as the Fecal Indicator Bacteria (FIB) Escherichia coli and the environmental pathogen Burkholderia pseudomallei. The methods suggested to be implemented in this PhD will be a mix of in… Continue Reading
An inter-disciplinary team at Bengaluru’s Indian Institute of Science (IISc) studied how different tree species partition underground water resources up to 30m depth and co-existing tree species diverge in water uptake depths (M-TROPICS/BVET). Deep rooted trees turn to be more vulnerable to severe droughts than shallow rooted species : climate… Continue Reading
