Forests play a vital role in preventing global warming and building sustainable societies. So the need to protect and develop them can never be stressed enough. Japan's substantial forests make it a notable example. In brief, that is the message of the government report on forests and forestry released last week.

The white paper, the first to be prepared under the Forest and Forestry Basic Law that took effect last July, points out various problems, including financial ones, that stand in the way of forest conservation. The government has its work cut out: fleshing out the basic program approved by the Cabinet last October.

Forests have a variety of functions, including land conservation, securing of water sources, control of climate change, and creation of natural environs essential to human existence. The law gives new value to these "multifunctional" forests with a view to achieving harmony between them and society.
