Two-fifths of Amazonian forest is at risk

8:20am, April 5, 2006

The Amazon basin's forest will lose 2.1 million square kilometers of its 5.3 million km2 by 2050 if current development trends go unabated, according to a new projection. However, aggressive policy changes could prevent deforestation on 1.3 million km2 of the threatened area, scientists report in the March 23 Nature.

Last week, at the eighth United Nations conference on biodiversity in Curitiba, Brazil, the Brazilian government announced that it now protects nearly 800,000 km2 of Amazonian forest and has beaten a 2012 deadline for achieving that goal.

But governments in the region will need to set aside more protected areas and simultaneously curtail forest clearance by private landowners to prevent substantial deforestation, say researchers led by Britaldo Silveira Soares-Filho of the Federal University of Minas Gerais in Belo Horizonte, Brazil.
