Keeping the balance


Forests can only provide useful products if they are allowed to grow and develop naturally. It is important not to disrupt the complex relationships between the various plants and animals. If too many trees are removed, or if too many animals are killed, the forest' s equilibrium is upset and it cannot function properly.

If a forest is to be used, the best way to keep its natural balance is to harvest it sustainably - i.e. take only as much of any product as the forest can afford to give.

In some parts of the world, people take timber and other forest products without upsetting the forest' s natural equilibrium. They understand the importance of ensuring that future generations inherit healthy forests.

Harvesting forest products sustainably can be profitable. A recent study in Peru showed that by sustainably harvesting products, one hectare of forest could be worth just under US$7,000. But if all the marketable timber was cut down at once, that hectare would bring in a once only US$1,000.

Human activities can even enhance forests. On the slopes of Mount Kilimanjaro in Tanzania, the Chagga tribe blends crops into the rainforest. They imitate the natural forest structure, keeping the tallest trees, and creating different layers of fruitful undergrowth. At the highest level they grow banana, papaya, and guava. Then comes coffee and finally, close to ground level, vegetables. Fish swim in the irrigation channels. Pigs, goats, cows, and chickens provide valuable protein and their dung is a useful source of fertilizer.
