Land use change from annual crops to commercial tree plantations can modify flow and transport processes at the watershed scale, including the fate and transport of fecal indicator bacteria (FIB), such as Escherichia coli. The objective of this study was to provide a comprehensive assessment of the impact of land… Continue Reading
High rainfall intensities on slopes produce runoff and erosion, but seeds are also carried down slope into streams by surface wash, causing weed infestation in lower parts of a river system. This interdisciplinary study was performed in the Houay Pano catchment (M-TROPICS/MSEC in Laos), farmed by smallholders and equipped with… Continue Reading
A documentary film (Dong Cao, des racines & des Hommes, 9’04) featuring Jean-Luc MAEGHT (IRD) and PHAM Dinh Rinh (SFRI) has been shot within the Dong Cao catchment in Vietnam (M-TROPICS/MSEC) to highlight the long term monitoring of the CZO (climate, land use, hydrology, and soil erosion, root density, macrofauna,… Continue Reading
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.
