Impact of Offshore Sand Mining on Sandy Beach in Coral Reef Environment - Case Study in Kinenhama Beach, Tokunoshima Island, Japan

Offshore sand mining in coral reef environments, particularly in the southwestern islands of Japan such as Tokunoshima Island, poses risks to coastal stability and ecosystems. A study focusing on Kinenhama Beach revealed that while direct harm to sandy beaches or dunes from sand extraction is currently absent, offshore mining for construction materials may contribute to shoreline erosion within coral reefs. Researchers conducted field surveys and numerical simulations to assess the impact of sand mining in the Kinenhama region, emphasizing the need for quantitative analysis to ensure sustainable practices that do not compromise coastal resilience or biodiversity.
