Life in the water
(lakes, lagoons, the coast and the sea)

Along an aquatic continuum, from the sources of rivers to their mouths, passing through freshwater lakes and wetlands to reach seas and oceans, aquatic ecosystems are strongly connected to each other and are highly impacted. humans.

Anthropogenic footprint, increasing exposure or resilience of aquatic biodiversity in Côte d'Ivoire

Presenter & author: Allassane Ouattara (MARBEC, Nangui Abrogoua University, Ivory Coast)

 

Côte d'Ivoire has diversified aquatic ecosystems (rivers, lakes, lagoons, ocean) which support important services but are subject to intense anthropogenic pressures (overexploitation, galloping demography, anarchic urbanization, multiple pollution). The absence of an ambitious policy compromises the maintenance of their uses and seriously threatens the preservation of their biodiversity.

We deal with the regression of Posidonia oceanica caused by anthropogenic pressures and environmental factors in a context of global change in order to identify new solutions for its conservation.

P. oceanica is an indicator of the quality of its environment. By crossing its spatial distribution with biological and anthropogenic pressure data, we are proposing new indicators that are easy to calculate at the scale of the French coast. These results point to multiple applications for improving marine management and surveillance in the French Mediterranean.

Port Environmental Monitoring Platform of the port of Cotonou (Benin): maritime transport and dissemination (invasive species for example)

Presenter: Gauthier Dobigny (IRD, France) & Arlette Tchabi (Health, Safety, Environment, Quality and Transversal Projects Department of the Autonomous Port of Cotonou, Benin)

 

The scientific results (biology, environmental law, economy) obtained in the port of Cotonou (Benin) prompted a strong response from the authorities: the creation of the first port platform for environmental monitoring in Africa. Based on a partnership between academic and operational players, it aims to prevent bio-invasions linked to maritime transport.

Baye Cheikh Mbaye, post-doctoral fellow Sorbonne University / IRD.

His research areas are the study of interactions between ocean physics, biogeochemistry and marine ecosystems, with particular emphasis on the role of environmental effects on the composition of plankton, the survival of the early life stages of fish (eggs and larvae) and the dynamics of fish populations. Its main research tools are regional, individual and end-to-end models.
