Deforestation imperils biodiversity, but some trends encouraging – UN

4 October 2010 – High rates of deforestation and degradation of woodlands continue to threaten the world's forest biodiversity, the United Nations Food and Agriculture Organization (FAO) said today, but pointed out that there is a positive trend towards the conservation of forests in many countries.

Globally, around 13 million hectares of forests were converted to other uses – including agriculture – or were lost through natural causes each year between 2000 and 2010, according to the findings of FAO’s Global Forest Resources Assessment 2010. The trend of forest loss has declined from around 16 million ha per year during the 1990s, the report said.
