Abstract

Vegetation monitoring using vegetation indices is widely applied in satellite image analysis to understand vegetation distribution and density. However, its accuracy is often affected by atmospheric disturbances and soil background noise. MSARVI (Modified Soil and Atmospheric Resistance Vegetation Index) was developed to address these issues, yet its application remains limited. This study aims to analyze vegetation density and evaluate the accuracy of the MSARVI index using Sentinel-2A imagery in Cigugurgirang Village. The methodology includes processing Sentinel-2A imagery to calculate MSARVI values, classifying vegetation density levels, and validating results using field reference data. MSARVI is computed by integrating atmospheric and soil background corrections to enhance vegetation detection accuracy. The results indicate that Cigugurgirang Village is predominantly covered by high-density vegetation, spanning an area of 147.71 ha. The accuracy assessment yielded an overall accuracy of 87.50% and a kappa accuracy of 83.34%, demonstrating high reliability. These findings confirm that MSARVI is an effective method for vegetation density mapping with high accuracy.

Abstract

River degradation poses a serious threat to ecological stability and global public health. While environmental awareness continues to grow, it is often not accompanied by commensurate concrete action. This study aims to identify factors that bridge the gap between awareness and action in river rehabilitation programs. Through a systematic literature review of 46 academic articles (2020–2025) grounded in the SMCR communication model, this study examines the mechanisms that translate awareness into collective action. Key findings reveal a "Participation Paradox". Developed countries employing sophisticated campaigns experience a larger awareness-action gap due to one-way communication practices. Conversely, developing countries are more successful because they employ a dialogic approach based on community and trust. The "collective storytelling" mechanism, pioneered by community leaders, has proven to be the most effective in converting awareness into concrete action because it fosters trust and shared agency. In conclusion, dialogue and trust are far more crucial than technological sophistication. Management institutions must shift their role from mere information disseminators to dialogue facilitators. This study encourages practitioners to adopt community-based strategies and engage local leaders as catalysts for behavior change for successful river restoration.
