Green algae in Brittany: A challenge for Integrated Coastal Zone Management

The transition to sustainable practices is slow due to economic constraints.

Small farms, often the most vulnerable, lack resources to invest in these changes.

4. Scientific Research and Algae Valorization

Research focuses on the potential valorization of green algae:

• Energy Production: Projects like Green Algae Energy, funded by the French ecological transition agency (ADEME), test transforming collected algae into biogas or organic fertilizers.

• Biomaterials: Other studies explore their use in biodegradable plastics.

Results:      
These initiatives remain experimental, but they could provide sustainable solutions to reduce treatment costs while creating economic opportunities.

Proposed Solutions in the ICZM Framework

ICZM encourages holistic, integrated solutions combining ecological, economic, and social dimensions. Potential improvements include:

1. Strengthening Agricultural Regulations with Economic Incentives

• Targeted Subsidies: Provide additional aid for farmers adopting zero-nitrate practices or transitioning to organic farming. According to an OECD report (2021), such subsidies could reduce nitrate inputs by an additional 30%.

•
