Interactions between microbes and minerals occur in a vast array of natural and contaminated environments. In this talk, I will discuss these interactions in the context of processes such as biomineral formation, and remediation of polluted environments.

In situ field studies in thawing permafrost regions have shown that organic carbon (OC) geochemical stability and therefore its emissions resulting from decomposition depends a.o. on the variability in soil water content, which can be directly related to microtopography.

Recently, large self-supervised pre-trained models such as GPT-3 (ChatGPT), Bert (Google), InceptionV3, … have shown that they can outperform previous state-of-the-art models and transfer to different tasks and domains. In remote sensing, a large amount of unlabelled data are freely available but gathering in situ dataset is costly.

The Sun plays an important role in defining the environment of Earth and around. It is a source of life, but in some occasions may represent a danger as well. In this presentation a concept of Space Weather and Space Climate will be explained.

Over the last decade, the economic literature has produced a wealth of evidence that demonstrates that agricultural sectoral growth is not only good for poverty reduction, but in most contexts, it has a larger poverty-reducing effect than growth in other sectors. However, sectoral evidence covers a few cases, and more empirical studies are necessary due to heterogeneous factors between countries.

Dans le cadre de la défense de thèse de Jean-Claude Maki Mateso, le Dr Yannick THIERY du BRGM (France) donnera un séminaire illustrant les travaux du BRGM sur les glissements de terrain en contexte tropical avec une focus sur ses travaux récents au Malawi et/ou en Nouvelle Calédonie.
