Notas do Editor
- Russia has the most extensive forest cover, followed by Brazil, Canada and USAEstimated area of gross forest cover loss at the global scale is 1,011,000 km2, or 3.1 % of year 2000 forest area (0.6% per year from 2000 to 2005)Gross forest cover loss was highest in the boreal biome, with fire accounting for 60 % of that lossThe humid tropics had the second-highest gross forest cover loss, due mainly to broad-scale clearing for agriculture in Brazil, Indonesia and MalaysiaWhen expressed as proportion lost from the 2000 extent estimates, the humid tropics is the least disturbedThe Amazon interior is the largest remaining ‘intact’ forest, followed by the Congo basinThe dry tropics has the 3rd-highest gross forest cover loss, with Australia, Brazil, Argentina and Paraguay accounting for most of thisAlthough the temperate biome had the lowest forest cover (due mainly to forest clearances long, long ago), it had the 2nd-highest proportional gross forest cover lossNorth America has the greatest area of gross forest cover loss, followed by Asia and South AmericaNorth America alone accounts for ~ 30 % of global gross forest cover loss, and has the highest proportional gross forest cover loss at 5.1 %Brazil has the highest gross national forest cover loss of any nationIndonesia and the Democratic Republic of Congo are next in line for tropical countriesUSA has the highest proportional global forest cover loss since 2000Despite previous estimates suggesting that Canada has had little forest loss, the new estimates place it second in terms of gross forest cover loss only to Brazil
- 1990-2000: nearly 100 000 people were killed and 320 million people were displaced by floods, with total reported economic damages exceeding US$1151 billion
