Strategies to minimise impact/effects

Rainforest sustainability - Costa Rica

Many developing countries like Brazil need to exploit their rainforest resources to help them become more developed. To ensure the rainforest is conserved for future generations, sustainable development is absolutely crucial for its survival.

There are various management strategies in place to help conserve the forest.

National parks

Areas of rainforest can be protected from any commercial developments by passing laws which ensure they are conserved.

Agro-forestry

Growing trees and crops at the same time allows farmers' crops to benefit both from the shelter provided by the trees and from the nutrients provided by the dead leaves. It also prevents soil erosion as the tree roots hold the soil in place.

Sustainable Forestry Schemes

In each area of rainforest, experts can work out how many trees can be cut down without causing irreparable damage to the environment. These trees can then be cut down, as long as the same numbers of trees are replanted.

Selective logging

Trees are only cut down when they reach a certain height. This gives young trees an assured life span and allows the area of rainforest to regain full maturity after approximately 30-50 years.

Education

Making sure that the companies and people involved in the exploitation and management of the rainforest realise the consequences of their actions.

Afforestation

Planting more trees helps to maintain the canopy.

Monitoring

Using satellites to take aerial photographs of areas of rainforest to check that any activities taking place are authorised and sustainable.
