A Century of Sand Debt Comes Due in Malibu
Malibu is facing the consequences of a century of coastal sand mismanagement, a problem being described as 'sand debt' now coming due. Decades of development, dams and armoring of the shoreline have starved the famous beaches of the sediment that naturally replenishes them, leaving the coastline increasingly vulnerable to erosion and rising seas as climate change accelerates. The story highlights how restoring sand supplies is becoming an urgent and costly challenge for the community.
Why now: Coastal erosion and climate adaptation are drawing fresh attention as Malibu's beaches visibly shrink.
