This is a fine reward for Professor André Füzfa, astrophysicist in the Department of Mathematics and head of the Astronomical Observatory at UNamur. On November 21, he received the "Coup de Coeur" award from the Trophées de Matière Grise, RTBF's popular science program 2024. These trophies aim to reward the country's scientists, who mobilize to disseminate their knowledge and insights to the general public.

Well hidden from passersby, caves nevertheless conceal particularly aesthetic secrets. For the past four years, Martin Vlieghe has been pursuing a PhD in geology at UNamur.  He is exploring the origin of the surprisingly varied colours of certain concretions nestled in the heart of Belgian and French caves. Together with Prof. Johan Yans and Gaëtan Rochez, he samples, observes, and analyses these magnificent objects with the aim of uncovering the mysteries they conceal.

In the coming months, the University of Namur will participate in an exceptional space mission aboard the International Space Station (ISS), alongside Belgian astronaut Raphaël Liégeois. The BeBlob project, led by researchers Boris Hespeels (ILEE Institute) and Anne-Catherine Heuskin (NARILIS Institute), aims to study the DNA repair capabilities of a fascinating organism: the blob (Physarum polycephalum).

Alexandre Mauroy has been a professor and researcher in the Department of Mathematics for almost 10 years, working in the field of dynamical systems. He is also Director of the naXys Research Institute, which puts its expertise in complex systems at the service of UNamur researchers from all disciplines. Aware of the sometimes austere reputation of maths among the general public, Alexandre Mauroy works to demonstrate that this discipline is at the heart of today's technological and scientific challenges..

Today, our planet is undergoing major climatic changes. Particularly in the face of rising temperatures, it is not easy to predict how flora and fauna will react and adapt in disturbed ecosystems. International research, in which Professor Johan Yans' team (Department of Geology and ILEE Institute) is taking part, has found some answers in fossils, which have been the memory of Darwinian evolution for millions of years. Explanations.

It's official: the University of Namur joins the Réseau d'Échanges et de Liaisons entre Institutions d'Enseignement Supérieur Francophones (RELIEF). It thus becomes the fourth partner in this network, alongside the Université du Québec à Trois-Rivières (UQTR), the Université Savoie Mont Blanc and the Haute École Spécialisée de Suisse Occidentale (HES-SO).

Microplastics (MPs) are now ubiquitous in aquatic ecosystems, where their bioavailability to organisms and potential entry into the food web raise serious environmental and public health concerns. Substantial progress has been made in understanding MP toxicity, and their hazardous potential is now widely acknowledged. However, MP toxicity studies remain complex, as multiple particle characteristics, such as size, shape, polymer type, and sorbed contaminants might influence both bioavailabilityTo bridge this gap, the present thesis adopted a dual, complementary approach: (i) characterizing the environmental occurrence and bioavailability of MPs, and (ii) assessing the ecological relevance of using environmentally derived MPs in in vivo toxicity experiments.Overall, this thesis provides insights into the reproductive and transgenerational effects of environmentally relevant MPs while underscoring the importance of considering particle-pollutant interactions. By combining in situ field data with in vivo laboratory experiments, it demonstrates that the use of environmentally derived MPs represents a more realistic and ecologically meaningful approach to hazard characterization. Further studies should be carried out in this same perspective to generate robust, exploitable data and contribute to establishing a comprehensive MP risk characterization.

South America is a subcontinent rich in natural and cultural resources. Between biodiversity preservation and development cooperation, UNamur maintains valuable partnerships to address the challenges of biodiversity loss and understand current socio-economic transformations.

JuryProf. Nicolas DENDONCKER (UNamur), PresidentProf. Sabine HENRY (UNamur), SecretaryDr. Sébastien DUJARDIN (UNamur)Prof. Pierre OZER (ULiège)Prof. Emmanuel TWARABAMENYE (University of Rwanda)Prof. Caroline MICHELLIER (MRAC and UCLouvain)AbstractThis research investigates community vulnerability to landslides and floods in Northwestern Rwanda, hazards that frequently interact to produce compound disasters. The research focused on understanding the institutional, social, and structural factors that shape vulnerability and adaptive capacity in this disaster-prone region. Using a mixed-methods approach at local-scale, including institutional analysis, household surveys (n = 904), and field observations, the research highlights how vulnerability is shaped by socio-economic conditions, weak institutional coordination, and limited adaptive capacity. A Contextualized Vulnerability Index (CoVI) was developed to map vulnerability patterns, revealing particularly high vulnerability in landslide-prone and dual-hazard zones. The analysis of adaptive capacity showed that while awareness of hazards is high due to lived experiences, financial constraints, and limited technical knowledge hinder communities' ability to adapt effectively. The study contributes to the literature on social vulnerability and disaster risk reduction by emphasizing the importance of locally grounded, evidence-based strategies to strengthen community resilience in hazard-prone regions.

This doctoral study assesses pathways to enhance coastal sustainability in the Anthropocene, by promoting the sustainable use of mangroves and strengthening their social-ecological resilience through an interdisciplinary approach. The thesis is structured into four specific objectives: assessing the role of traditional beliefs and local deities in promoting the sustainable use of mangroves, analyzing the synergies between legal frameworks and traditional beliefs in enhancing the social-ecological resilience of mangroves, developing a novel interdisciplinary framework to evaluate the social-ecological resilience of mangroves, and operationalizing the proposed framework in Benin's mangroves, West Africa.  We collected field data using ethnobiological surveys, drone image analysis and document review, in-depth interviews, focus group discussions, plant and fish inventories across three coastal communities in Benin. The study draws insights from the seven principles of resilience to analyze mangrove sustainability. The interdisciplinary methodology of this study links plant biology, fisheries sciences, and human geography to analyze mangroves as complex social-ecological systems. Findings of the thesis show that traditional beliefs and local deities play a significant role in regulating the use of mangrove resources, while the overlapping of formal and informal institutions offer opportunities to enhance their social-ecological resilience. The novel proposed framework called Mangrove Social Ecological Resilience Appraisal (MaSERA) outlines variables and indicators tailored to mangroves to assess their social-ecological resilience. Its application in Benin highlights its potential in identifying factors that enable or erode mangrove resilience, for informed decision making. The study argues that promoting the sustainable use of mangroves and enhancing their social-ecological resilience represent dual imperatives for achieving coastal sustainability in the Anthropocene. It contributes to the growing body of knowledge on mangrove conservation and provides actionable insights for integrated coastal zone management.
