VOICED: France's coastal communities cope with beach erosion

The video discusses coastal erosion and its impact on communities. Technicians use GPS to track land loss, estimating erosion rates of 1-3 meters per year. Quettehou is at risk due to its clay bluffs, and the town invests in defenses despite high costs. Capbreton innovates with a hydraulic system to move sand and maintain beaches, reducing truck use. Coastal communities strive to protect the environment while supporting tourism, as full beaches attract visitors.
