In a groundbreaking initiative, Italy is mapping its entire coastline to enhance the conservation of Posidonia oceanica seagrass meadows, which play a critical role in marine ecosystems and carbon sequestration. The project, part of a larger €400 million marine restoration effort, utilizes advanced technology, including multispectral satellites and autonomous underwater vehicles, to create a high-resolution digital map of coastal habitats. This mapping is crucial as it provides updated information on the health and extent of seagrass meadows, which have been severely impacted by human activities such as pollution and illegal fishing. The initiative aims to reverse ecological degradation and support the global goal of protecting 30% of the world's oceans by 2030. As the project progresses, it is expected to yield valuable insights into marine biodiversity and inform effective conservation strategies.
