What’s going on:
Researchers from the Coastal Geology Group at the University of Hawaii (UH) at Mānoa School of Ocean and Earth Science and Technology recently revealed a new study that current policies aren’t enough to stop beaches in Oahu from eroding.
The researchers reviewed the shortlines that would be vulnerable to sea levels rising, which are estimated to occur before the middle of the century.
- “We found that emergency permit applications for shoreline hardening to protect beachfront property will substantially increase,” said Kammie Tavares, graduate researcher involved with the project.
- This means about 40% of beaches could be lost due to hardened shorelines.
What it means:
New policies will need to be considered to help protect the lands from erosion, Tavares said in a statement.
- “Beaches are critical ecosystems to native plants and animals, offer protection from storms, are an essential cultural setting and attract tourists who are important for Hawaii’s current economy,” said Tavares. “This research shows that conversations on the future of our beaches and how we will care for them must happen now rather than later, if we are to protect our sandy beaches.”
