Mitigating Coastal Eutrophication with Drs. Wafa Malik and Patrick Durand

“Nitrogen mitigation scenarios to reduce coastal eutrophication” with Wafa and Patrick.

Eutrophication is a state of overgrowth of aquatic plants, such as algae and seaweeds, in water bodies due to the excessive pouring of nutrients from different sources like agriculture, industry, and human settlements, causing disturbances to the ecosystems. Coastal eutrophication is a major issue worldwide due to the increasing discharge of nutrient emissions from agricultural activities into coastal ecosystems. Several efforts have been made to reduce eutrophication, achieving up to 35–40% reduction, but these measures are not sufficient to eliminate the problem. For more sustainable and effective solutions, the root causes of the nutrient emissions, especially nitrogen, need to be addressed in current agricultural practices. In this episode, Drs. Wafa Malik and Patrick Durand share their research on the reduction of coastal eutrophication in Brittany, France, focusing on changing cropping systems and reducing the sources through modeling the effectiveness of different approaches and taking into consideration the interests of farmers and the local community.
