Forest loss across the world has slowed, largely due to a switch from felling to planting in Asia. China, Vietnam, the Philippines and India have all seen their forested areas increase in size.Many severe problems remain, especially with regard to old growth forests. Discussed at the link.
There are also gains in Europe and North America, but forests are being lost in Africa and Latin America driven by rising demand for food and firewood...
Although 52,000 sq km were lost per year between 2000 and 2010, that was a marked improvement on the 83,000 sq km annual figure seen during the previous decade.
Europe traditionally has been the region with the biggest increase; but now, Asia has overtaken it. A net loss of forest in Asia during the period 1990-2000 has been transformed into a net gain in the decade since.
"China has increased its forest by three million hectares (30,000 sq km) per year - no country has ever done anything like this before, it's an enormous contribution," said Eduardo Rojas-Briales, assistant director-general of the FAO's forestry department.
"But we can also highlight the case of Vietnam, a small and densely populated country that's implemented very smart and comprehensive forest reform - or India, which has not controlled its population as China has and where standards of living are even lower.
"Nevertheless India has achieved a modest growth of its forest area, and the Philippines has turned things around as well - so we're seeing improvement across Asia except in the weakest states," he told BBC News.

Forest loss slowing worldwide
I remember reading taht the United States has more forest land now than in the 1920s, and more hardwood now than 50 years ago. But I hadn't realized that similar changes have occurred in other countries. The BBC presents some information from the UN Food and Agriculture Organization's (FAO) State of the World's Forests report:

When reviewing accounts like this we need to ask a few probing questions such as: Are the the "new" forests equal in biodiversity and carbon storage relative to the "old" forests? Often biologically rich native forests are being replaced with tree farms.
ReplyDeleteThat's why I included the second link with the data about hardwood trees.
ReplyDeleteThere was also this article from the Telegraph this week -

Really does read like a report with a specific agenda to me.
ReplyDeleteThe dwindling forests in S America are NOT driven by the need for firewood.
Better to move in this direction.
ReplyDeleteBut if you drive through a state like Ohio you will notice really dense areas of woods that for whatever reason have not been touched... then when you realize that all of the state used to look like that, you gasp. Over 90% of it had been removed at one point! Forest cover is just now approaching 30% again, but you will only notice if you are in the correct part of the state.
