Les arbres sont un domaine de travail tres complexes : leur culture et leurs besoins en matiere d’elagage dépendent des conditions environnementales, systemes agricoles, traditions culturelles, regimes fonciers et pressions economiques.
The exploitation of arbres is a vey important issue for populations rurales, whose utilisation of trees enables them to meet certain basic needs, such as food and water. However, a number of problems can arise which jeopardise the future of these flora and fauna.
La destruction of forestry: L’exploitation des arbres is a vey grave problem that afflicts many regions of the world, including Asia, Africa and South America. It is due to a number of factors, including climatic changes, a loss of soil and forest cover, and the effects of human activity on the environment.
In a number of regions, the destruction of forests has been accompanied by the disappearance of forestry techniques which were once commonplace and the creation of new ones that are less adapted to the environment or which impose greater risks. In a number of areas, a wide range of tree species are now endangered or have disappeared altogether.
A number of forestry techniques are still used, but they are often not sustainable. They can lead to a loss of biodiversity, or to the spread of diseases that afflict these plants.
The use of a variety of plantation techniques aimed at maximizing yields can help to sustain the productivity of these crops. Moreover, some of these techniques are ecologically sound and do not involve the use of harmful chemicals (for example, pesticides) or the application of heavy metals to the soil.
Le utilisation d’un eclaircie – a technique of plantation which involves the interplanting of several trees – has a number of advantages. It can improve the quality of the soil and reduce erosion. It can also promote the formation of secondary growths which are necessary for the survival of some forestry species.
This technique can be used in an agricultural setting to increase the amount of wood a reforestation site, but it should not be used on trees that are already well established in the landscape.
Alternatively, it can be used on trees that are still young and in a stage of regrowth. It will help to stimulate their development, but it should be complemented with other activities aiming at maintaining the health of the trees.
A lot of forestry techniques can be applied to the reforestation of an area, but they should always be accompanied by a commitment to the conservation of the existing flora and fauna. This will ensure that the trees are not killed off by a series of disasters, such as fires, or that their natural life cycle is not disrupted. The best way to do this is to establish an active programme of reforestation and maintenance. This will ensure that the reforestation projects are sustainable and will allow a continued production of food and other products. It will also be possible to keep a close eye on the progress of the plantation, which will ensure that it is not causing too much damage to the environment.
