ベチバーグラスは深い根と高い引張強度で斜面安定化と重金属汚染土壌の浄化を同時に実現する二目的バイオエンジニアリング手法である。気候変動に起因する地滑りへの自然ベースの対策として、伝統的なハードエンジニアリングに代わる選択肢を提供する。
English
This study highlights vetiver grass as a dual-purpose bioengineering solution for climate-resilient landscapes, combining slope stabilization via deep, strong roots with phytoremediation of heavy-metal-contaminated soil and water. Its evapotranspiration reduces pore water pressure, preventing rainfall-induced slope failures, while its self-regulating detoxification helps reclaim polluted land.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は山岳地や有人島など斜面災害リスクが高く、SSBJやグリーンインフラ政策の中で自然由来解決策（NbS）への関心が高まっている。ベチバーは法面緑化やため池周辺の侵食対策など国内適用例もあり、気候適応策としての実装可能性を示す。
In the global GX context
Globally, this work supports the integration of nature-based solutions into climate adaptation and disaster risk reduction, aligning with frameworks like the UN Sendai Framework and the EU's green infrastructure strategy. It offers evidence for replacing hard engineering with cost-effective, multi-benefit vegetation in hillslope and contaminated land management.

📄 Abstract（原文）
Vegetation is a strong resource for scalable, climate-resilient infrastructure in mainstream disaster mitigation, but its potential is largely unexplored. This study identifies vetiver grass as a distinctive, dual-purpose bioengineering solution that successfully integrates ecological restoration with geotechnical stability. The study illustrates vetiver's significant ability to stabilize susceptible slopes and remediate contaminated land concurrently. In terms of geotechnical stability, vetiver is a natural alternative to traditional hard engineering, helping protect against the growing threat of landslides, directly or indirectly caused by climate change. Its root system promotes stability due to its dense, deep roots and good tensile strength, thereby providing both mechanical support and hydrological control. The roots make the soil stick together better, increase the friction angle and shear strength, and allow the soil to withstand greater ductile deformation. Vetiver's extensive root system acts like a natural sponge, absorbing moisture through evapotranspiration. This action lowers pore water pressure and prevents saturation, which is the main cause of slope failure during rain. It also improves soil water retention and air entry suction. Vetiver is a great plant for cleaning up contaminated soil and water, and it has developed a remarkable self-regulating mechanism that allows it to thrive in and detoxify environments contaminated with heavy metals (like Pb, Cd, Zn, As, and Cu), high salinity, and xenobiotics.
