Congratulations to Yann Emmanuel Sonagnon Miassi for the brilliant and successful defense of his PhD thesis!
Congratulations to Yann Emmanuel Miassi, who successfully and brilliantly defended his PhD in Forest Sciences on April 29, 2026!
His thesis, entitled  « Analysis of the Circularity of Woody Forest Products in West Africa: An Innovation Serving the Timber-Forest Sector in Benin », examines the potential of integrating the circular economy into the timber-forest sector in Benin, while highlighting the technical, financial, and institutional challenges to its adoption, as well as the essential role of training, information, and partnerships.
This achievement crowns a rigorous research work conducted under the supervision of Professor Nancy Gélinas (Laval University).
We also thank the members of the jury: Marie-Hélène Vandersmissen (Chair), Bertrand Laratte (examiner, UL), Bocar Samba Ba (examiner, UL), and Adanhounme Armel Brice (Université du Québec à Trois-Rivières) for their expertise and valuable feedback, which greatly enriched this defense.
Congratulations, Yann Emmanuel Miassi, on this significant and inspiring milestone, which reflects a remarkable journey shaped by perseverance and excellence!
Title:Â Analysis of the circularity of wood forest products in West Africa: An innovation serving the wood-forest sector in Benin
Abstract:Â In a context of forest resource degradation and ecological urgency, this study examines the integration of the circular economy in the wood-forest sector in Benin. It is based on an approach combining a literature review, field surveys with stakeholders, and statistical analyses.
The results show that circularity goes beyond simple recycling to include the valorization of residues, eco-design, operational optimization, and collaborative practices such as lending and exchange. Despite growing awareness, these practices remain underdeveloped and often informal.
The adoption of circular strategies depends on key factors such as access to information, training, professional experience, partnerships, and the socio-economic profile of stakeholders. Significant regional disparities also influence adoption dynamics.
Although these strategies are perceived as beneficial environmentally, economically, and socially, their implementation is hindered by technical, financial, and institutional constraints, particularly the lack of infrastructure, the complexity of processes, and insufficient regulatory frameworks.
Thus, the transition toward an effective circular economy requires increased investment in training, innovation, incentive public policies, and partnerships in order to strengthen the sustainability of the wood-forest sector.
