Eau-environnement-littoral-biodiversite-CEVA

As a water manager or manager of natural habitats, whether local or regional authorities, state services, economic or agricultural stakeholders or maritime professionals, you are most probably concerned about the quality of the environment and status of coastal ecosystems (notably in terms of algal resource).

Indeed, water quality (seawater or fresh water) is a main issue when reporting to the European Commission on the quality status of water bodies, evaluating the quality of bathing or recreation areas, measuring the quality of effluents from your operating sites or again the impact of pollution on your aquaculture resources.

Increased exploitation and use of the marine environment in response to economic, societal (tourism) and environmental (marine renewable energies) issues, lead to usage conflicts. Such evolving situations require a more balanced and sound management as well as more appropriate consultation processes than experienced previously.

With a better knowledge and understanding of species, interactions between each other and with their surrounding environment, the CEVA offers a sustainable development and management of the “algae” resource. This offer is in line with its ambitions and vision, whether applied in a natural environment context or in a cultivation perspective based on selected strains from culture collections (see Aquaculture / Sourcing Business Area).

The CEVA, mainly through its research and development activities, contributes in monitoring and improving the quality of water, aquatic environments and associated biodiversity and hence to take action on pollution control efforts (seaweed as a solution in complex phyto-purification systems).
