World deforestation rates and forest cover statistics, 2000-2005 New deforestation figures show Nigeria has worst rate of forest loss Rhett A. Butler, mongabay.com November 16, 2005 November 17, 2005 [update] Monday, the Food and Agriculture Organization of the United Nations (FAO) released its 2005 Global Forest Resources Assessment, a regular report on the status world's forest resources. Overall, FAO concludes that net deforestation rates have fallen since the 1990-2000 period, but some 13 million hectares of the world’s forests are still lost each year, including 6 million hectares of primary forests. Primary forests -- forests with no visible signs of past or present human activities -- are considered the most biologically diverse ecosystems on the planet. Industrial logging, clearing and forest conversion for agriculture, fuelwood collection by rural poor, and forest fires -- often purposely set by people -- are considered the leading causes of deforestation. South America South America -- where large tracts of the Amazon rainforest are being cleared for cattle ranches and soybean plantations -- suffered the largest net loss of forests between 2000 and 2005 of around 4.3 million hectares per year. Scientists are concerned that forest loss could escalate in the Amazon due to increasingly dry conditions. This year the Amazon suffered the most severe drought on record, leaving rivers dry and communities stranded. Tens of thousands of fires burned. Africa
FAO figures also show Africa is more dependent on bushmeat -- wild animals captured as food -- than other tropical regions. Bushmeat availability has increased with the construction of logging roads in the rainforest and a number of well-known species including gorillas, chimpanzees, and monkeys are considered at highest risk. There is growing concern among health experts that bushmeat consumption may be linked to the outbreak of unusual tropical diseases including the Ebola virus and Marburg, which broke out earlier this year in Angola. Primates are known to be carriers of these diseases. Central America, South Asia, and Southeast Asia lead deforestation rates The regions with the highest tropical deforestation rate were Central America -- which lost 1.3% or 285,000 hectares of its forests each year -- and tropical Asia. Tropical Asia --
Plantations offsetting natural forest Due to a significant increase in plantation forests, forest cover has generally been expanding in North America, Europe and China while diminishing in the tropics. Plantations help offset the loss of natural forests but essentially result in an overall decline in global biodiversity as single species plantations replace their biologically richer natural counterparts. The United States The United States has the seventh largest annual loss of primary forests in the world, according to FAO. In the 2000-2005 period, the United States lost an average of 831 square miles (215,200 hectares, 2,152 square kilometers or 531,771 acres) of such lands which are sometimes termed "old-growth forests."
Overall, when plantations are added to the picture, the US gained a net 614 square miles (159,000 hectares) of forest per year. The FAO report suggests America's primary forests are losing ground to modified natural, seminatural, and plantation forests. Earlier this year, the government revoked President Clinton's 2001 "Roadless Area Conservation Rule" that protected 58.5 million acres of undeveloped national forest, in effect opening more than 90,000 square miles of forests to road construction, logging and industrial development. UN figures contested
Despite the criticism, industry experts say that FAO has the best figures available across virtually all countries in the world. Mila Alvarez, who tracks forest trends for World Resources Institute and Global Forest Watch (globalforestwatch.org), told the New York Times "The F.A.O. is doing the best it can given what the governments are providing." Alvarez says the World Resources Institute and other organizations are developing a way to use satellite imagery to analyze forest changes and to verify government estimates. More deforestation information: Nigeria has worst deforestation rate, FAO revises figures More deforestation news deforestation blog (5/16/2008) Nearly one third of the world's wildlife has been lost since 1970, according to a study released by the Zoological Society of London, WWF and the Global Footprint Network. Prince Charles calls for rainforest protection to fight climate change (5/15/2008) Ending the destruction of tropical rainforests is the simplest step to helping address climate change, said Prince Charles in an interview with the BBC. Brazil will forge its own path for developing the Amazon (5/15/2008) The Brazilian government will use cheap loans, payments, and other benefits to encourage Amazon farmers to reduce their impact on the Amazon rainforest, under a plan unveiled last week Tropical deforestation is 'one of the worst crises since we came out of our caves' (5/15/2008) Speaking at the Asia-Pacific Forestry Week in Vietnam, keystone speaker Dr. Norman Myers stated: "I'm going to give you my bottom-line message right now, up front, this is a super crisis that we are facing, it's an appalling crisis, it's one of the worst crises since we came out of our caves 10,000 years ago. I'm referring of course to elimination of tropical forests and of their millions of species." After acquittal, fear of open season on activists in the Amazon rainforest (5/14/2008) Bishop Flavio Giovenale was crushed by the acquittal last week of a rancher accused of ordering the killing of a crusading American nun — and not just because he admired Dorothy Stang. Giovenale, who spends much of his time battling child prostitution, police corruption and drug abuse, fears the verdict means it's open season again on activists in the Amazon jungle state of Para.
