Mangrove Species Mapping in Coastal China Using Synthesized Sentinel-2 High-Separability Images

The first national-scale mangrove species map for China, covering nine species at 10 m resolution, achieved 83.8-86.4% accuracy and revealed extensive planting of exotic species in mid-latitude regions where they outcompete native mangroves.

Near Real-Time Monitoring of Tropical Forest Disturbance by Fusion of Landsat, Sentinel-2, and Sentinel-1 Data

A fusion algorithm combining Landsat, Sentinel-2, and Sentinel-1 detects 70% of tropical forest disturbances within 30 days at 91% user accuracy, significantly outperforming any single-sensor approach, with the full implementation publicly available on Google Earth Engine.

Refining land-use-specific carbon emission factors for commodity-driven deforestation monitoring in Colombia

Pasture expansion drives 65% of Colombia's deforestation emissions; cocoa and coffee show high emission factors despite small areas.

Global extent and drivers of tree cover loss quantified with high-resolution satellite data

Nearly 30% of 277,000 km2 of global tree cover loss in 2018 resulted in permanent forest conversion, quantified at 3-10m resolution.

Fire dynamics in the South American Chaco and their link to agriculture and drought

65% of the Gran Chaco has burned since 1985; 70% of fires are clearing fires linked to deforestation, not natural climate drivers.

High-resolution Planet Dove data identify local drivers of kelp canopy persistence

AI analysis of 23,000 Planet Dove images reveals local drivers of kelp persistence after California's marine heatwave at 3m resolution.
