Landslides are among the most devastating natural hazards, exacerbated by climate change, deforestation, and rapid urbanization. Conventional engineering measures such as retaining walls, drainage systems, and slope reinforcement can be effective but are often costly, environmentally disruptive, and not always sustainable in the long term. Nature-based solutions (NBS) have recently gained recognition as an alternative approach that leverages ecological processes to stabilize slopes while providing co-benefits for biodiversity, water management, and local communities. This review focuses on various NBS methods for landslide mitigation, including afforestation, bioengineering, slope vegetation cover, and watershed management practices. Case studies demonstrate how vegetation root reinforcement, agroforestry, and ecological buffers contribute to reducing slope instability and sediment displacement. The review findings suggest that NBS are environmentally friendly, economically viable, socially acceptable, and adaptable to local conditions. However, challenges remain due to time-intensive establishment, site-specific performance variability, and the absence of standardized evaluation systems, which hinder large-scale implementation. Future directions emphasize the integration of NBS with geotechnical monitoring and engineering solutions, the use of remote sensing and artificial intelligence for performance assessment, and active community involvement to enhance long-term sustainability.
