Eco-friendly Biopolymer for Sustainable Coastal Erosion Prevention
Proportion of the area of the contribution comprising Key Biodiversity Areas: 0%
Korea National Park Service (KNPS) succeeded in restoring the eroded coast of Gwanmae-do Island, Jindo-gun, in the Dadohaehaesang National Park with eco-friendly technology using biopolymer-based natural paving materials. The existing techniques to prevent coastal erosion, using cement concrete structures or natural stone masonry, cause physical problems, such as dislocation and cracking over time after construction. In addition, cement structures lose toxic substances, which destroy the surrounding ecosystem and adversely affect nearby landscapes. A biopolymer-based natural paving material is a blend of high-molecular compounds extracted from plants and natural aggregates such as gravels. It contains many pores on the surface and inside. Therefore, when a strong wave hits the surface, seawater is dispersed between the pores, which significantly lowers the wave energy and increases the durability of the structure.
Potential conservation benefits in saving biodiversity
Potential reduction of species extinction risk resulting from threat abatement actions
Absolute value (STAR)
1% of the total biodiversity conservation potential of Republic of Korea is covered by this project.
0.3% of Asia's biodiversity conservation potential is from Republic of Korea.
25.9% of global biodiversity conservation potential is from Asia.
The chart below represents the relative disaggregation of the selected contribution's total potential opportunity for reducing global species extinction risk through taking actions to abate different threats to species within its boundaries. The percentages refer to the amount of the total opportunity that could potentially be achieved through abating that particular threat.
