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.

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.

At UNamur, parchments are much more than objects of curiosity: they are at the heart of an interdisciplinary scientific adventure. Starting with historical sciences and conservation, the research has gradually incorporated the disciplines of physics, biology, chemistry, and archaeology.  This convergence has given rise to research in heritage sciences, driving innovative projects such as Marine Appart's doctoral work, supervised by Professor Olivier Deparis. This research has now been recognized with a publication in the prestigious journal Heritage Science (Nature Publishing Group).

At a time when bacterial resistance to antibiotics is a public health problem, Professor Stéphane Vincent's team is currently developing dynamic constitutional frameworks (Dynamic Constitutional Frameworks, DCF): a molecular system that would be able to break down certain resistances and thus deliver antibiotics as close as possible to pathogens.

AbstractIn CO2-rich atmospheres such as that of Venus, the study of water vapor requires the use of H2O collision parameters for CO2. However, due to a lack of data, models still use collision parameters for air to estimate the abundance of water vapor in this type of atmosphere. In this thesis, new experimental laboratory measurements of the collision parameters of H2O, HDO, and D2O by CO2 were carried out. These were then used as the basis for dedicated theoretical calculations. Their impact was evaluated using radiative transfer simulations applied to the atmosphere of Venus, under conditions close to those of future observations by the European EnVision mission. The results clearly show that using collision parameters for air instead of CO2 can lead to an overestimation of nearly 40% of the abundance of water vapor in the mesosphere and to inversion difficulties in the troposphere. This work thus provides essential elements for improving the spectral analysis of CO2-rich atmospheres.JuryDr. Ha TRAN (Sorbonne University), ChairProf. Muriel LEPÈRE (University of Namur), SecretaryDr. Emmanuel MARCQ (University of Versailles)Dr. David JACQUEMART (Sorbonne University)Dr. Laurence RÉGALIA (University of Reims)Dr. Séverine ROBERT (Royal Institute for Space Aeronomy, Belgium)
