His work at the Muséum National d’Histoire Naturelle has helped to better understand the evolutionary impact of human activities on biodiversity. He offers an in-depth reflection on the links between biodiversity crises and environmental transformations, providing valuable insights for understanding today’s challenges.
Talk: Biodiversity and Climate in Crisis: What Is the Reality of Past and Future Changes?
Dive into the heart of today’s major environmental challenges by exploring the impact of human activities on biodiversity and the climate. This talk will give you a comprehensive understanding of the ongoing upheavals, from biogeochemical cycles to the dynamics of animal and plant populations. You’ll leave with key tools to grasp past, present, and future changes, as well as their implications for our society.
Themes: biodiversite, ethique, transition-ecologique, transition-societale, environnement, ecologie, changement-climatique, climat, societe
Cédric FONTAINE
For nearly twenty years, Cédric Fontaine has been dedicated to promoting the value of rainwater, supporting individuals, communities, and industries in the practical management of this resource. As vice-president of the ATEP’s rainwater commission, he shares an educational, accessible, and pragmatic approach to untangling misconceptions and encouraging concrete action. His commitment sheds light on today’s water-related challenges—a central issue in adapting our regions to environmental changes.
Talk: Understanding Rainwater, Plain and Simple: Sorting Fact from Fiction Between Drought and Flood, and Finally Knowing What to Do With the Rain That Falls at Home Caught between drought and flooding, rainwater raises many questions and misconceptions. In this talk, Cédric Fontaine will help you separate fact from fiction: how the water cycle works, the impacts of climate change, and practical solutions you can adopt at home. Leave with a clear vision and practical answers to better manage rainwater in your daily life.
