Mayotte

Mayotte, a French department located in the Indian Ocean northwest of Madagascar, is bordered by a lagoon of 1500 km² among the largest and most biodiverse. Due to the ever-increasing demographic pressure, the island of Mayotte is extremely polluted by the significant urban development on the coast and an increase in the quantity of domestic wastewater (EUD) produced, of which only 30% is treated by wastewater treatment plants.
Within the framework of the European Water Framework Directive (WFD), which aims to maintain or restore the “good ecological status” of water bodies, LEMAR participates in the development of benthic bioindicators of the quality of coastal water bodies, specific to the Mayotte meadows and mangroves.

Ongoing projects:

• Bioindicators for Herbariums project: Study of the biological functioning of overseas herbariums with a view to developing a bio-indicator for monitoring Transitional Water Bodies and the Overseas Coastal Water Body, and, development of methodological tools for monitoring and evaluating the health status of the overseas meadows and their environment within the framework of IFRECOR and the WFD. P.I.: F Kerninon, UMR LEMAR (2017-2019)
• Mangrove Bioindicators Project: Study of the biological functioning of mangrove sediments with a view to developing a bio-indicator for monitoring Transitional Water Bodies and the Overseas Coastal Water Body; P.I.: T Meziane, UMR BOREA & LEMAR leader: E Michaud (2018-2019)
