Building the information system of the French Critical Zone Observatories network: Theia/OZCAR-IS

The French Critical Zone research infrastructure, OZCAR-RI, gathers 20 long-term observatories monitoring and sampling various compartments of the critical zone. Each observatory developed its own data management and distribution systems. The paper presents the common information system Theia/OZCAR IS that was built to make in situ observation FAIR (findable, accessible, interoperable, reusable). Within M-TROPICS, Norbert Silvera from iEES Paris participated to the paper that was just published in the Hydrological Sciences Journal.

Village settlements in mountainous tropical areas, hotspots of fecal contamination as evidenced by Escherichia coli and stanol concentrations in storm water pulses

Little is known about the contribution of villages to the fecal contamination of surface water in tropical rural areas. This study, published in the journal Environmental Science & Technology, documents E. coli and stanol concentration levels in surface runoff, and tracks the origin of the fecal contamination during flood events.

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 […]

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 […]
