Today October 17, 2018, Huong Thi LE successfully defended her thesis on the impacts of landuse change on stream microbial communities in rural, tropical catchments. Huong’s field work was performed within two M-TROPICS catchments: Houay Pano in Laos and Dong Cao in Vietnam. Her research was supervised by Thomas POMMIER… Continue Reading
Paty Nakhle is a former student from both the Lebanese University and the Agronomy Engineering School of Toulouse (ENSAT), with a specialization in environmental science. She also hold a joint ENSAT/Paul Sabatier University master degree Ecosystèmes et Anthropisation and performed her 6-month internship at GET laboratory, where she experimentally modelled… Continue Reading
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)… Continue Reading
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
