Conferences
An oral presentation was given at the annual SWAT International Conference in Brussels by Minjeong Kim, from UNIST, South Korea, about the modelling of E. coli: a research work using data of the Houay Pano catchment in Laos (M-TROPICS/MSEC), already published in the Journal of Environmental Quality (here).

Groundwater contribution to streamflow sustains biodiversity and enhances ecosystem services, especially under monsoon-driven climate where stream baseflow is often the only available water resource during the dry season. This study assessed how land use change influences streamflow and its groundwater contribution in the small headwater catchment of Houay Pano (M-TROPICS/MSEC) in the lower Mekong basin, […]

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 use change on microbial transfer […]

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 eight gauging stations. Main findings […]
Movies
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, carbon), the benefits of erosion […]
Workshop
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 color, sediment sources characterization, bacteria […]
Events
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).
Events
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 at the heart of water, […]
Events
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 organic carbon stored in sediments […]
