The illustration on the cover shows a satellite image mosaic of Sumatra and Borneo provided by the VEGETATION instrument on the SAPOT -4 satellite. The mosaic offers an overview of the forest cover of that region with a quality of detail not available until now. The image illustrates the alarming situation which is found in this key area of the Southeast Asian ecological realm. Forest cover monitoring is critical and the capabilities of the VEGETATION instrument and of its data exploitation system appear to satisfactorily cope with the problem of persistent cloud cover in the region. The displayed image was produced from VEGETATION S10-composites. S-10- Composites from April to September 1998 and from march to November 1999, including some image segments from January to march 2000 were further combined. When comparing results from a first digital classification of the present mosaic with existing maps from WCMC the loss of forest cover on Sumatra and Borneo amounts about 10 and 25 percent of the total land cover respectively.
