Geospatial Tools and Remote Sensing Strategies for Timely Humanitarian Response: A Case Study on Drought Monitoring in Eswatini
This article explores the escalating impact of natural disasters, particularly droughts, in the Southern African Development Community (SADC), with a specific focus on Eswatini. Over the last century, approximately 63 million people in SADC countries have ...
Basel2024Associations between inorganic arsenic in rice and groundwater arsenic in the Mekong Delta
Rizlan Bernier-Latmani, Matthew Charles Reid
There is growing concern regarding human dietary exposure to arsenic (As) via consumption of rice. The concentration and speciation of As in rice are highly variable, and models describing rice As speciation as a function of environmental covariates remain ...
2021Robust and sustainable cultivation of microalgae: recycling of nitrogen from liquid digestate and control of biological contamination
The present doctoral thesis aimed to achieve a robust cultivation of microalgae by recycling nitrogen from a liquid digestate. However, the use of non-sterile nutrient source increases the risks of contamination of undesired organisms such as bacteria, vir ...
EPFL2021Variability in arsenic methylation efficiency across aerobic and anaerobic microorganisms
Rizlan Bernier-Latmani, Karin Lederballe Meibom, Karen Elda Viacava Romo, Arnaud Michel Gelb, Leia Soraya Véronique Falquet, Shannon Eliot Dyer, Adrien Mestrot
Microbially-mediated methylation of arsenic (As) plays an important role in the As biogeochemical cycle, particularly in rice paddy soils where methylated As, generated microbially, is translocated into rice grains. The presence of the arsenite (As(III)) m ...
2020Methylation of arsenic by single-species and soil-derived microbial cultures
Arsenic (As) is simultaneously a ubiquitous and a toxic element. Arsenic is subject to bio-transformations catalyzed by microorganisms constituting the As biogeochemical cycle. The primordial Earth was devoid of oxygen, exposing life to the highly mobile a ...
EPFL2020Genetic variation and evolutionary history of a mycorrhizal fungus regulate the currency of exchange in symbiosis with the food security crop cassava
Most land plants form symbioses with arbuscular mycorrhizal fungi (AMF). Diversity of AMF increases plant community productivity and plant diversity. For decades, it was known that plants trade carbohydrates for phosphate with their fungal symbionts. Howev ...
2020Intergranular Strain Evolution During Biaxial Loading: A Multiscale FE-FFT Approach
Helena Van Swygenhoven, Steven Van Petegem
Predicting the macroscopic and microscopic mechanical response of metals and alloys subjected to complex loading conditions necessarily requires a synergistic combination of multiscale material models and characterization techniques. This article focuses o ...
Springer2017Arsenic methylation dynamics in a rice paddy soil anaerobic enrichment culture
Rizlan Bernier-Latmani, Julien Maillard, Alexandre Bagnoud, Leia Soraya Véronique Falquet, Matthew Charles Reid
Methylated arsenic (As) species represent a significant fraction of the As accumulating in rice grains, and there are geographic patterns in the abundance of methylated arsenic in rice that are not understood. The microorganisms driving As biomethylation i ...
Amer Chemical Soc2017Life Cycle Assessment of Vetiver-Based Biorefinery With Production of Bioethanol and Furfural
Edgard Gnansounou, Jegannathan Kenthorai Raman
Lignocellulosic biomass feedstocks are considered as one of the major alternative for fossil and food based transport fuel and chemicals for the reasons such as fuel/food security, depleting fossil reserves, climate change, mitigate pollution in agricultur ...
Elsevier2017Effects of flooding on phosphorus and iron mobilization in highly weathered soils under different land-use types: Short-term effects and mechanisms
The strong affinity of phosphorus (P) to iron (Fe) oxides and hydroxides in highly weathered tropical soils limits P availability and therefore plant productivity in tropics. In flooded soils, however, P fixed by Fe oxides and hydroxides can be released in ...
