Sunshine and a pinch of tropical soils: A natural, low-cost photo-Fenton variation for safer water, assisted by H2O2 or percabonate

Michaël Bensimon, César Pulgarin, Stefanos Giannakis, Jérémie Decker, Thomas Guillaume

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 ...

Lowland plant arrival in alpine ecosystems facilitates a decrease in soil carbon content under experimental climate warming

Alexandre Buttler, Pierre Rémi Mariotte, Konstantin Svetlozarov Gavazov, Constant Signarbieux, Thomas Guillaume

Climate warming is releasing carbon from soils around the world, constituting a positive climate feedback. Warming is also causing species to expand their ranges into new ecosystems. Yet, in most ecosystems, whether range expanding species will amplify or ...

Legacy effect of green manure crops fertilized with calcium phosphite on maize production and soil properties

Alexandre Buttler, Mario Fontana, Luca Bragazza, Thomas Guillaume, Mathieu Raymond Santonja

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) ...

Valorization of calcium phosphite waste as phosphorus fertilizer: Effects on green manure productivity and soil properties

Alexandre Buttler, Mario Fontana, Luca Bragazza, Thomas Guillaume, Mathieu Raymond Santonja

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 ...

Riparian wetland properties counter the effect of land-use change on soil carbon stocks after rainforest conversion to plantations

Thomas Guillaume

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 ...

Measured greenhouse gas budgets challenge emission savings from palm-oil biodiesel

Thomas Guillaume

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 ...

Utilization of research knowledge in sustainable development pathways: Insights from a transdisciplinary research-for-development programme

Jessie Madrazo Bacallao, Thomas Guillaume

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 ...

Transpiration on the rebound in lowland Sumatra

Mitsunori Nomura, Thomas Guillaume

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 ...

Drivers of soil carbon stabilization in oil palm plantations

Alexandre Buttler, Juan Carlos Quezada Rivera, Thomas Guillaume, Johanna Katharina Rüegg, Mathieu Raymond Santonja

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 ...

Carbon neutral expansion of oil palm plantations in the Neotropics

Alexandre Buttler, Juan Carlos Quezada Rivera, Thomas Guillaume

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 ...

Effects of flooding on phosphorus and iron mobilization in highly weathered soils under different land-use types: Short-term effects and mechanisms

Thomas Guillaume

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 ...

Slash-and-burn agriculture and tropical cyclone activity in Madagascar: Implication for soil fertility dynamics and corn performance

Alexandre Buttler, Justine Marie Gay des Combes, Robert Thomas Edmund Mills, Bjorn Jozef Maria Robroek, Thomas Guillaume

On the western coast of Madagascar, the dry tropical forest of Kirindy may disappear in the next 50 years because of its rapid conversion into agricultural land by slash-and-burn cultivation. The slash-and-burn fields are cultivated during 3 years in avera ...

Land-use change affects phosphorus fractions in highly weathered tropical soils

Thomas Guillaume

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 ...

Sensitivity and resistance of soil fertility indicators to land-use changes: New concept and examples from conversion of Indonesian rainforest to plantations

Thomas Guillaume

Tropical forest conversion to agricultural land leads to a strong decrease of soil organic carbon (SOC) stocks. While the decrease of the soil C sequestration function is easy to measure, the impacts of SOC losses on soil fertility remain unclear. Especial ...
