Effects of climate and anthropogenic changes on current and future variability in flows in the So’o River Basin (south of Cameroon)

Due to climate and environmental changes, sub-Saharan Africa (SSA) has experienced several drought and flood events in recent decades with serious consequences on the economy of the sub-region. In this context, the region needs to enhance its capacity in water resources management, based on both good knowledge of contemporary variations in river flows and reliable […]


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 […]


M-TROPICS at JFFoS 2022 in Kyoto

Laurie Boithias presented M-TROPICS datasets collected in Mekong river basin, Lao PDR, at the interdisciplinary Japanese-French Frontiers of Science (JFFoS) Symposium 2022 in Kyoto, Japan: small and large catchment-scale climate, hydrology, and water quality long-term monitoring data including E. coli.


Escherichia coli concentration, multiscale monitoring over the decade 2011–2021 in the Mekong River basin, Lao PDR

Bacterial pathogens in surface waters may threaten human health, especially in developing countries, where untreated surface water is often used for domestic needs. The objective of the long-term multiscale monitoring of Escherichia coli concentration in stream water, and that of associated variables (temperature, electrical conductance, dissolved oxygen concentration and saturation, pH, oxidation-reduction potential, turbidity, and […]


Groundwater irrigation reduces overall poverty but increases socioeconomic vulnerability in a semiarid region of southern India

The development of irrigation is generally considered an efficient way to reduce poverty in rural areas, although its impact on the inequality between farmers is more debated. In fact, assessing the impact of water management on different categories of farmers requires resituating it within the different dimensions of the local socio-technical context. This study, led […]


Distribution of Burkholderia pseudomallei within a 300‑cm deep soil profile: implications for environmental sampling

The environmental distribution of Burkholderia pseudomallei, the causative agent of melioidosis, remains poorly understood. This study performed in Lao PDR and supervised by Alain Pierret (IRD-iEES Paris) and Olivier Ribolzi (IRD-GET), in the frame of the PhD of Khemngeun Pongmala, provides novel information about a putative association of soil biogeochemical heterogeneity and the vertical distribution […]


AI4Water v1.0: an open-source python package for modeling hydrological time series using data-driven methods

Machine learning has shown great promise for simulating hydrological phenomena. However, the development of machine-learning-based hydrological models requires advanced skills from diverse fields, such as programming and hydrological modeling. Additionally, data pre-processing and post-processing when training and testing machine-learning models are a time-intensive process. In this study led by Ather Abbas, PhD student at UNIST, […]


Impact of Rainfall Variability and Land Use Change on River Discharge in South Cameroon

Climate change, climate variability, and anthropogenic forcings such as land use change are the main drivers of river discharge variability. However, an understanding of their simultaneous impacts on river discharge remained limited in some parts of the world. The objective of this article led by Valentin Brice Ebodé from the University of Youndé, Cameroon, was […]
