English
This study integrates geophysical surveys, soil physicochemical analyses, vegetation dynamics, and rainfall data to diagnose slope instability on tropical red-soil slopes in Indonesia, proposing site-specific Nature-Based Solutions (NbS) such as contour planting of bamboo, organic biopores, drainage control, and organic amendments. It demonstrates how integrated diagnostics can inform evidence-based NbS recommendations for preventing shallow slope instability and promoting sustainable land restoration.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、気候変動適応策としてのNbSや防災・減災の文脈で参考になるが、GX開示や脱炭素政策との直接的な関連は薄い。日本の斜面防災技術や生態工学との比較研究として価値がある。
In the global GX context
Globally, this paper contributes to the growing literature on Nature-Based Solutions for climate adaptation and disaster risk reduction, particularly in tropical regions. It offers a practical framework for integrating environmental diagnostics into NbS design, which is relevant for climate resilience planning and sustainable land management.

📄 Abstract（原文）
Gentle slope instability in tropical red-soil landscapes is commonly driven by subsurface saturation, nutrient depletion, and progressive weakening of soil structure. This study characterized slope conditions in Sukamelang, Subang, West Java, Indonesia, through integrated geophysical surveys, soil physicochemical analyses, seasonal vegetation dynamics, rainfall records, and field observations to support site-specific Nature-Based Solution (NbS) design. Electrical Resistivity Tomography (ERT) revealed shallow low-resistivity zones (<35 Ω.m) beneath the upper terraces, whereas higher resistivity values in the lower terraces indicated comparatively stable subsurface conditions. Soil physicochemical analyses showed persistently high moisture (>80%), acidic conditions (pH 5.2–5.6), and depleted N, P, and K concentrations (<20 mg kg⁻¹), indicating nutrient leaching and declining soil quality under repeated rainfall. Seasonal analyses of NDVI and rainfall patterns provided complementary information on vegetation dynamics and the timing of preventive NbS implementation by identifying periods of reduced vegetation cover and increased rainfall that are associated with greater susceptibility to runoff and soil degradation. Based on these integrated environmental diagnostics, site-specific NbS recommendations were developed by linking diagnosed environmental constraints with stabilization measures supported by published evidence. The proposed interventions include contour planting of Dendrocalamus asper for biomechanical reinforcement, organic biopores and controlled drainage for hydrological regulation, organic amendments for soil restoration, and productive crops to maintain continuous vegetation cover and support sustainable livelihoods. The findings demonstrate how integrated environmental diagnostics can be translated into evidence-based Nbs recommendations for tropical red soil slopes, providing a practical framework for preventing rainfall-induced shallow slope instability while promoting sustainable land restoration and agricultural productivity.
