The Global Burnt Area 2000 initiative GBA-2000 GBA 2000: Final Results and Perspectives J-M. Grégoire & K. Tansey with E. Binaghi, L. Boschetti, P.A. Brivio, D. Ershov, S. Flasse, R. Fraser, D. Graetz, M. Maggi, P. Peduzzi, J.M.C. Pereira, J.M.N. Silva, A. Sousa and D. Stroppiana Global Land Cover 2000 “Final Results” Workshop March 2003
GBA-2000 Product definition • a binary map (burnt-unburnt) monthly non-accumulative global burn scar map, at 1 km resolution • statistics of burnt areas area burnt in 2000 per country, per month, and • per main types of vegetation cover
Total annual burned area estimated at 3.5 million km2 > 600,000 burn scars detected
Seasonal distribution of burning activity in Africa for the Year 2000 Africa: Total annual burned area estimated at 2.6 million km2 > 300,000 burn scars detected
