Satellite Forensics & Volumetric Earth-Removal Investigation
An advanced geospatial and field-level investigation by Black Lens 2.0 has mapped the scale of illegal topsoil removal and sand dredging across the Kasba region. Using Copernicus Sentinel-2 satellite imagery combined with digital volumetric tracking, the investigation reveals a systematic destruction of local agricultural infrastructure and biomass degradation.

đ°ī¸ Copernicus Sentinel-2 JIT Satellite Verification
Geospatial analysis focused on biomass index tracking (NDVI) between May 2025 and May 2026 confirms severe environmental disruption. Agricultural zones that registered healthy vegetation indices in 2025 have deteriorated significantly, with biomass indexes dropping below 0.4, pointing to extensive earth-moving activity. Approximately 15% of local agricultural land in targeted hotspots has been converted into waterlogged dredging craters.
âī¸ Local Enforcement & Regulatory Action
Following reporting by Black Lens, the Ministry of Land issued warning directives under the Land Crime Prevention and Redress Act, 2023. Local administration conducted multi-hour raids resulting in fines of 1 Lakh BDT and the arrest of 4 operators involved in illegal dredging. However, field reports suggest that sand-lifters continue to operate under political cover in zero-line border areas.
