Remote Sensing based monitoring of tropical deforestation and forest degradation on Borneo - methods and results

*Andreas LANGNER(Joint Res. Centre, Euro. Comm.)

On the island of Borneo deforestation and forest degradation have been rampant in the last decades, leaving only some mountainous regions and very few lowland rainforest areas untouched. Satellite remote sensing datasets, such as the Tropical Moist Forest (TMF) add to the hitherto existing Global Forest Watch (GFW) data, providing reliable tree cover loss information on pantropical scale. Even though both datasets rely on optical Landsat imagery (spatial resolution 30m), TMF is able to depict more subtle changes due to single-date analysis and allows extending the monitoring period back to the 1980s as compared to GFW, which covers the years from 2000. For more recent years, even finer spatial details can be detected using the radar-based Forest Canopy Disturbance Monitoring (FCDM-radar) tool that uses 10m Sentinel-1 data. Further advantage of FCDM is its adaptability to specific user requirements, e.g. adjustment of sensitivity, customization of the monitoring period and filtering options. All above-described monitoring approaches come at no cost to the user and the data could potentially be ingested in smartphone apps that allow the access in the field, which is handy for spotting potential encroachments in protected areas or surveying logging companies to follow their terms.
