AVHRR for Monitoring Global Tropical Deforestation

AVHRR DATA HAVE BEEN USED TO ASSESS THE DYNAMICS OF FOREST TRANSFORMATION IN THREE PARTS OF THE TROPICAL BELT. A LARGE PORTION OF THE AMAZON BASIN HAS BEEN SYSTEMATICALLY COVERED BY LAC DATA IN THE 85-877 PERIOD; THE ANALYSIS OF THE VEGETATION INDEX AND THERMAL DATA LED TO THE IDENTIFICATION AND MEASUREMENT OF LARGE AREAS OF ACTIVE DEFORESTATION. THE KALIMANTAN/BORNEO FOREST FIRES WERE MONITORED AND THEIR IMPACT WAS EVALUATED USING THE GAC 4 KM RESOLUTION DATA. FINALLY, HRPT DATA HAVE PROVIDED PRELIMINARY INFORMATION ON CURRENT ACTIVITIES TAKING PLACE AT THE BOUNDARY BETWEEN THE SAVANNA AND THE FOREST IN THE SOUTHERN PART OF WEST AFRICA. THE AVHRR APPROACH IS FOUND TO BE HIGHLY VALUABLE TOOL FOR CARRYING OUT DEFORESTATION ASSESSMENTS IN REGIONAL AND GLOBAL PERSPECTIVES.
