“…Other studies have emphasized the role of vegetation types in influencing erosion rates [20]. Specifically, in the upper Citarum region in 2020, within the Mandalahaji village of the Bandung sub-district in West Java, monocultural landscapes experienced erosion at a rate of 14.95 tons per hectare annually, while regions dominated by agroforestry practices had erosion rates of 1.5 tons per hectare each year [21].…”

To address challenges in soil erosion management and ecological rehabilitation, understanding the determinants of soil erosion is crucial. This research aims to achieve two primary objectives: (1) delineating the spatial patterns of soil erosion within the designated region and (2) identifying the influential factors using the Multiscale Geographical Weighted Regression (MGWR) methodology. The methodological framework involved the creation of grid datasets, with soil erosion as the response variable and a combination of physical and socioeconomic attributes as predictors. We extracted 550 data points from raster datasets, specifically centered on village locations, using the ‘extract multi-value to point’ tool in ArcGIS. The R Studio environment was utilized to select the relevant factors influencing soil erosion. The geographical detector technique was applied to determine the explanatory power of each determinant concerning the spatial patterns of soil erosion. Subsequently, data from the Ordinary Least Squares (OLS) model underwent MGWR analysis. The findings reveal that the Central Citarum Watershed experiences an estimated annual soil erosion of 23.16 million tons, averaging 102.01 tons per hectare. The analysis identified LS (slope length and gradient) and CP (vegetative cover and supportive practices) as the primary variables influencing the spatial variability of soil erosion. Notably, the MGWR model demonstrated enhanced explanatory capacity and effectiveness compared to both the OLS and Geographically Weighted Regression (GWR) methodologies.

“…Karlina's research [13] on the Erosion of the Upstream Citarum Watershed in Bandung Regency gave the results that the erosion class in the Upstream Citarum Watershed area was dominated at level 2 (16-60) with dry land farming, a land cover of rice fields, and level 3 (60-180) land cover of mixed gardens and secondary forest. Further research [14] showed that the level of erosion depends on the types of plants that are on it. For example, the amount of erosion in the upper Citarum area in 2020 (village at Mandalahaji village, Bandung sub-district, West Java province) gives a value of 14.95 tons/ha/year in areas with monocultures and 1.5 tons/ha/year in areas with agroforestry crops.…”

In addition to the problem of water availability and quality, the Citratum watershed is also experiencing problems with soil erosion and sedimentation. Climate change and land use cover are the leading causes of this. Therefore, monitoring water conditions and soil erosion is prioritized in the central Citarum watershed covering an area of 227,020 hectares. The purpose of this study was to determine soil erosion and the spatial distribution of sediment exports. The InVEST SDR method was used to calculate sediment exports and soil erosion. The results showed that the total sediment export of the Central Citarum watershed was 4.61 x million tons/year or an average of 20.31 tons/ha/year. Significant distributions occur in several sub-watersheds, including Cilawang, Cihalaya, Cipada, Citarum 58, and Cimurah, each contributing 36.56%, 14.83%, 13.70%, 4.73%, and 4.53 %. Meanwhile, total soil erosion is 23.16 million tons/year or an average of 102 tons/ha/year, with the most extensive distribution in the Cilawang sub-watershed, 35.12%. High sediment discharge occurs in areas with steep slopes, high rainfall, and dry land agriculture. Furthermore, efforts to reduce sediment exports to the Cirata and Jatiluhur reservoirs should focus on these five sub-watersheds.

The application of remote sensing data has been significant in modeling soil erosion. However, previous studies have fallen short in elucidating and lacked an understanding of the multifactor influencing erosion. This study addresses these limitations by employing the InVEST and the Geodetector models. Specifically, it aims (1) to delineate both spatial and temporal variations in soil erosion within the Citarum watershed from 2010 to 2020, (2) to identify the key drivers of soil erosion and unravel the underlying mechanisms, and (3) to identify the high-risk zones for soil erosion. Both models consider a range of natural predictors, including topography (slope factor), climate (precipitation factor), and vegetation cover (vegetation factor). In addition, they incorporate social parameters such as income per capita and population density, which interact with the watershed’s position in the downstream, middle, and upper streams. The results reveal that, over a decade, the average soil erosion increased by 15.50 × 106 tons, marking a 16.65% surge. The impact of factors varies significantly across different subwatershed areas. For example, fraction vegetation cover interactions influence upper- and middle-stream regions, while the downstream area is notably affected by precipitation interactions. The high-risk erosion areas in the watershed are primarily influenced by slope, precipitation, and fractional vegetation cover. In these areas, factors causing high erosion risks include slope, precipitation, and other environmental variables categorized into strata. The study highlights the varying influential factors in different watershed areas.
