“…By definition from the Earth Science perspective, Critical Zone is "heterogeneous near surface environment in which complex interactions involving rock, soil, water, air and living organisms regulate the natural habitat and determine the availability of life sustaining resources"(National Research Council, 2001). The critical zone mapping is crucial for forest management (Kopp et al, 2023). In a practical application in Indonesia, the context of critical zone is regulated and technically elaborated in the Peraturan Dirjen Bina Pengelolaan Daerah Aliran Sungai dan Perhutanan Sosial No: P.4/V-SET/2013, under the Ministry of Forestry.…”

Land use change, which contributes to a critical area, upstream of the Keureuto Sub-catchment is obvious based on previous studies. The critical area mapping is important for the watershed and land management considering the Keureto dam will be operated in the year 2024 at the downstream. The map can be categorized based on land cover, terrain slope, erosion risk classes, land productivity, and land management. The sub-catchment is prone to changes in all or any of these parameters. In this case, the initial critical zone map is developed for the 238 km2 Keureuto sub-catchment based on two parameters which are land use and terrain slope. Land use is produced from Landsat Satellite images from the years 2015 and 2021. Digital Elevation Model (DEM) data is used to produce terrain slope and sub-catchment boundary which the outlet is the Keureto dam. The analysis is based on overlaying the land cover and slope layer. Agricultural land covers part of the upstream area – steeper slope and middle – moderate slope of the sub-catchment increasing by about 8% within seven years. The critical zone mapping based on these two parameters is produced for a further study of the slope stability, the erosion risk, the watershed, and land management for the functionality of the Keureuto dam at the downstream site.

“…Bedrock is an essential component of the Earth's surface and can influence soil properties and microbial communities [17,18], thereby controlling SOM stability [19]. Additionally, the chemical composition of bedrock can influence plant growth and composition by regulating the release of mineral nutrients [20] and the water-holding capacity of the regolith [21], which consequently impacts C inputs and SOC fractions.…”

The stability of soil organic matter (SOM) plays a critical role in soil carbon (C) dynamics under global warming. However, the factors influencing SOM stability, particularly the significance of bedrock geochemistry and its hierarchical relationship with climate and soil properties, remain poorly understood. To address this gap, we conducted a study along a large climatic gradient (Δtemperature > 9 °C) in the subtropical karst forests of southwest China, quantifying SOM stability using thermal analysis and investigating the contributions of bedrock geochemistry, climate, and soil properties. Our results showed that SOM stability was positively correlated with mineral-associated organic C (MAOC) rather than particulate organic C. Hierarchical partitioning analysis further demonstrated that bedrock geochemistry was the predominant contributor to SOM stability variance, accounting for 23.7%. Following this, soil minerals contributed to 21.1%–22.6% of the variance, the mean annual temperature to 20.3%, and microbial biomass C to 17.2%. In particular, bedrock geochemistry—specifically the presence of calcium-rich bedrock—was found to enhance SOM stability by promoting the accumulation of exchangeable calcium and calcium carbonate in soils. Additionally, high temperature improved SOM stability by increasing the content and proportion of MAOC and soil pH. These results highlight the fundamental role of bedrock geochemistry in controlling SOM stability and emphasize the importance of considering hierarchical relationships among bedrock–soil–climate interactions for evaluating soil C dynamics.
