Deforestation rates were estimated using outdated aerial photos, leading to delayed policy response.

Automated satellite change‑detection reduced reporting lag to 48 hours, enabling rapid enforcement actions.

Wetland health assessments required manual field surveys each season.

Multispectral indices derived from Sentinel‑2 data provided quarterly health scores, cutting field time by 70%.

Air quality monitoring relied on sparse ground stations.

Integration of MODIS aerosol optical depth data offered city‑wide pollution maps, improving public alerts.

Coastal erosion was tracked inconsistently, missing critical hotspots.

High‑resolution SAR imagery identified erosion hotspots annually, guiding targeted shoreline protection.

Carbon sequestration estimates were based on generic models.

LiDAR canopy height models delivered site‑specific biomass calculations, increasing estimate accuracy by 25%.
