The economic crisis could disturb the balance by threatening the wood industry, which is the motor behind sustainable forestry.

The United Nations conference which led to the Kyoto Protocol described the forests as the 'stopgap'. When the negotiations threatened to grind to a halt, there were, luckily, always the forests. Dr Gert-Jan Nabuurs from the Alterra Institute for Environmental Issues in Wageningen agrees, certainly as far as Europe's woodland is concerned:

"In Europe, we have a large area of forest which is growing all the time. A lot of woodland was planted in the 1920s and 1930s. That's growing quickly now and absorbing CO2. That absorption of CO2 is important in combatting climate change."

Mixed fortunes

In general, European forests are doing well. They are gradually being expanded, mainly thanks to increasingly intensive farming which requires less and less space to yield the same harvest levels. The result is more room for woodland. The forests are also ageing, which means their ecosystems are more developed.

On the other hand, woodlands surrounding urban areas and affected by road construction are being threatened by factors such as air pollution. And, in the Mediterranean region, forest fires are on the increase due to warmer and drier conditions.

The fact that the situation is broadly going well despite these problems is largely due to the fact that the European wood sector's operations are broadly sustainable.

Unfortunately, this delicate balance is being threatened by the economic crisis, which is hitting industries such as paper and furniture production hard. Dr Nabuurs explains why this in turn threatens the forests' ability to absorb CO2:

"We think it's really positive that you don't just manage the woodland in a sustainable way but that you can, at the same time, continue to produce timber. The CO2 actually stays in the wood products. A book is to a large extent made up of CO2, just like a piece of wooden furniture... You can even reuse old products. Because the woodland is still growing and absorbing CO2, you have a snowball effect."

The danger is that the economic crisis will force wood producers to buy timber from Brazil, China or Russia. This will mean that European forests will gradually run wild. All very pretty, but not as effective as far as absorbing CO2 goes.

Copenhagen

The forests will again be seen as important in the negotiations at the forthcoming United Nations climate change conference in Copenhagen. In the current economic climate, countries are unwilling to introduce expensive measures to limit the emissions of industry and traffic.
