Per- and polyfluoroalkyl substances (PFAS) are global pollutants, yet data from tropical freshwater ecosystems remain scarce. This study provides the first assessment of PFAS occurrence in the Rusizi delta (Burundi), from tributaries to Lake Tanganyika, by analyzing water, sediment, macrophytes, and fish, and by evaluating human health risks from fish consumption. In water, only PFOA (<0.60–7.80 ng/L) was detected and showed a uniform spatial distribution. Sediment concentrations were largely below quantification limits, likely reflecting unfavorable sorption conditions. Macrophytes were dominated by short-chain PFAS, particularly PFBS, without consistent species- or site-specific patterns, supporting their potential as biomonitors of cumulative PFAS exposure. Fish exhibited the highest PFAS diversity, with more diverse profiles in liver than muscle, although tissue-specific patterns were often absent. PFBS was dominant across fish species, and emerging PFAS (e.g., PFBS and NaDONA) were frequently detected. Human health risks from fish consumption were, except for children, mostly below EFSA tolerable weekly intake values for regulated PFAS, but potential concern for adolescents and adults emerged when PFAS were expressed as PFOA equivalents. This study provides essential baseline data for tropical freshwater systems and highlights the need for expanded PFAS monitoring and risk assessment in data-poor regions.

This field guide specifically documents the aquatic flora of the Lagoon in Rusizi National Park (Delta Sector). It is intended as a resource for researchers as well as stakeholders in ecotourism, including park rangers, managers, and visitors. The book is the result of the RUBICOM project (Biodiversity and Adaptation to Climate Change in the Rusizi Plain), funded by VLIR-UOS. It is a collaborative effort between the University of Antwerp, University of Burundi and CEBioS. The project aims to lay the foundation for knowledge-based, sustainable coexistence between humans and biodiversity in Burundi’s Rusizi River Plain, with a particular focus on aquatic and wetland ecosystems.

Thesis Abstract: "Life experiences associated with cancer: a study of women living with breast cancer treated at at the Centre Hospitalo-Universitaire de Kamenge" Breast cancer represents a major global public health challenge and is the most frequently diagnosed cancer among women. In Burundi, breast cancer diagnoses are often delayed, and access to specialized care remains limited. Beyond the medical aspects, the disease profoundly affects the identity, body image, and femininity of the women involved, as well as their family and social relationships. This study examines the life experiences of women with breast cancer receiving care at at the Centre Hospitalo-Universitaire de Kamenge. It aims to understand their reactions to the diagnosis, analyze their psychological experiences throughout the course of treatment, and study their coping strategies in the face of the disease. The study employs a qualitative approach based on semi-structured interviews with four female volunteers. Thematic analysis revealed key findings, notably that receiving the diagnosis is a deeply distressing event characterized by shock, fear of death, a state of stunned disbelief, and anxiety about the future. Treatments also bring about physical changes that affect self-image, femininity, and relationships. To cope, patients draw upon family support, spirituality, a gradual acceptance of the illness, and trust in healthcare professionals. Thus, this study highlights the importance of a holistic approach to breast cancer that integrates psychological, social, and existential dimensions, and recommends strengthening psychosocial support within oncology care services in Burundi.
La problématique de la limitation des mandats présidentiels en Afrique des grands lacs : le cas du Burundi de 2015-2024

Presidential term limits are a fundamental principle of democracy, aimed at preventing the concentration of power in the hands of a single person or political party and ensuring the rotation of leaders. However, in the Great Lakes region, this principle is often marred by its Achilles' heel, as demonstrated by the case of Burundi in 2015, when President Pierre Nkurunziza, aided by a faction of the CNDD-FDD, attempted to run for a third term. The process of presidential term limits is rooted in the rule of law. However, if the rule of force prevails over the rule of law, weak institutions result. Therefore, term limits require strong leaders to build strong institutions. While the rule governing term limits existed in the constitution and the Arusha Peace and Reconciliation Agreement for Burundi, it lacked real force. The prevailing logic was neo-patrimonialism and monocentric presidentialism, which constituted the failure of presidential term limits. This was because the Head of State, aided by his party, treated the state as his private property. To understand this problem, sociohistorical theories of politics and constitutional theories were of great importance to us. Methodologically, we opted for a hermeneutic approach (reading works, statements, etc.), as well as a qualitative approach (a semi-structured survey conducted with representatives of political parties, civil society, and members of parliament). All these methods played a role in the development of this thesis. Pierre Nkurunziza's third term, supported by the CNDD-FDD party, was beneficial to those whose interests it protected, including himself, given its success. Despite its success, the opposition, civil society organizations, and some powers, including the international community, have condemned the CNDD-FDD for violating the law. This use of force has triggered a crisis that has led to murders and the exile of the country's children. This disregard for term limits has been facilitated by the vulnerability of democracy. The law has yielded to the interests of those in power. After analyzing various data and information from different informants, it is clear that Burundi has been characterized by conflict and political violence since its independence. This reinforces neo-patrimonialism and a one-sided presidential system, leading the ruling parties to view the state as a source of revenue for the ruling party.
