Sunshine and a pinch of tropical soils: A natural, low-cost photo-Fenton variation for safer water, assisted by H2O2 or percabonate
César Pulgarin, Michaël Bensimon, Stefanos Giannakis, Thomas Guillaume, Jérémie Decker
Clean water is essential for human survival, but access to safe drinking water remains a challenge in resource -limited regions. Herein, we explored a low-cost but effective solution for water potabilization using natural iron sources from soils along with ...
ELSEVIER2023Riparian wetland properties counter the effect of land-use change on soil carbon stocks after rainforest conversion to plantations
Progressive conversion of tropical rainforests to agricultural monocultures in South East Asia increasingly affects landscape types such as riparian areas. The impacts of conversions on soil organic matter (SOM) vary with changing landforms. However, this ...
2021Legacy effect of green manure crops fertilized with calcium phosphite on maize production and soil properties
Alexandre Buttler, Luca Bragazza, Thomas Guillaume, Mathieu Raymond Santonja, Mario Fontana
Recycling phosphorus (P) is crucial to meet future P demand for crop production. We investigated the possibility to use calcium phosphite (Ca-Phi) waste, an industrial by-product, as P fertilizer following the oxidation of phosphite (Phi) to phosphate (Pi) ...
ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD2021Valorization of calcium phosphite waste as phosphorus fertilizer: Effects on green manure productivity and soil properties
Alexandre Buttler, Luca Bragazza, Thomas Guillaume, Mathieu Raymond Santonja, Mario Fontana
The potential to use calcium phosphite (Ca-Phi) as phosphorus (P) fertilizer may represent an effective recycling of P-containing by-products. A greenhouse experiment was conducted to investigate the effect of Ca-Phi (38 kg P ha(-1)) on soil properties and ...
ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD2021Measured greenhouse gas budgets challenge emission savings from palm-oil biodiesel
The potential of palm-oil biofuels to reduce greenhouse gas (GHG) emissions compared with fossil fuels is increasingly questioned. So far, no measurement-based GHG budgets were available, and plantation age was ignored in Life Cycle Analyses (LCA). Here, w ...
2020Utilization of research knowledge in sustainable development pathways: Insights from a transdisciplinary research-for-development programme
Thomas Guillaume, Jessie Madrazo Bacallao
This study contributes to the ongoing discussion on how to attribute and evaluate the contribution of transdisciplinary research to sustainable development. As co-created knowledge is a key product of transdisciplinary research, we tested the hypothesis th ...
ELSEVIER SCI LTD2020Drivers of soil carbon stabilization in oil palm plantations
Alexandre Buttler, Thomas Guillaume, Mathieu Raymond Santonja, Juan Carlos Quezada Rivera, Johanna Katharina Rüegg
Increasing soil organic carbon (SOC) in agroecosystems is necessary to mitigate climate change and soil degradation. Management practices designed to reach this goal call for a deeper understanding of the processes and drivers of soil carbon input stabiliz ...
WILEY2019Carbon neutral expansion of oil palm plantations in the Neotropics
Alexandre Buttler, Thomas Guillaume, Juan Carlos Quezada Rivera
Alternatives to ecologically devastating deforestation land use change trajectories are needed to reduce the carbon footprint of oil palm (OP) plantations in the tropics. Although various land use change options have been proposed, so far, there are no emp ...
American Association for the Advancement of Science (AAAS)2019Transpiration on the rebound in lowland Sumatra
Thomas Guillaume, Mitsunori Nomura
Following large-scale conversion of rainforest, rubber and oil palm plantations dominate lowland Sumatra (Indonesia) and other parts of South East Asia today, with potentially far-reaching ecohydrological consequences. We assessed how such land-use change ...
ELSEVIER SCIENCE BV2019Land-use change affects phosphorus fractions in highly weathered tropical soils
Deforestation and land-use change in tropics have increased over the past decades, driven by the demand for agricultural products. Although phosphorus (P) is one of the main limiting nutrients for agricultural productivity in the tropics, the effect of lan ...
