No recycling of Water moisture from the oceans fall as rain on adjacent coastal regions. The moisture is soon sent up to the atmosphere through the transpiration of foliage to fall again on inland forest areas. This cycle repeats several times to rain on all forest regions. Less Carbon dioxide and Nitrogen Exchange The rainforests are important in the carbon dioxide exchange process. They are second only to oceans as the most important "sink" for atmospheric carbon dioxide. The most recent survey on deforestaiton and greenhouse gas emisions reports that deforestation may account for as much as 10 of current greenhouse gas emmisions.

Climate Change When an area of rainforest is either cut down or destroyed, there are various climate changes that happen as a result. The following is a list of the various climate changes with a brief description of why they come about. Desication of previously moist forest soil What happens is because of the exposure to the sun, the soil gets baked and the lack of canopy leaves nothing to prevent the moisture from quickly evaporating into the atmosphere. Thus, previously moist soil becomes dry and cracked. Dramatic Increase in Temperature Extremes Trees provide shade and the shaded area has a moderated temperature. With shade, the temperature may be 98 degrees Farenheit during the day and 60 degrees at night. With out the shade, temperatures would be much colder during the night and around 130 degrees during the day. Moist Humid Region Changes to desert This is related to the desicaiton of previously moist forest soil. Primarily because of the lack of moisture and the inability to keep moisture, soil that is exposed to the sun will dry and turn into desert sand. Even before that happens, when the soil becomes dry, dust storms become more frequent. At that point, the soil becomes usesless.

Provides forest products With an increase in demand for forest and timber products, afforestation is very valuable due to the umum explosion of livestock and human population. For that reason, construction of infrastructure has led to the demand of forest products. Stabilizes the climate Planting of trees in semi-arid areas attracts rainfall. This way, agricultural practices such as irrigation are carried out efficiently. In addition, afforestation acts as a catchment for water and soil conservation.(5).effect of deforestation when forests are killed, nature basically requires people to renew the forest. Reforestation is one concept that is in the opposite direction as deforestation, but is proven to be a much harder effort than deforestation. So the rate of deforestation has not been offset by the rate of reforestation. Thus, the world is now in a troubled state when it comes to issues concerning the environment.

Here are the main benefits of afforestation. Afforestation is useful especially metamorphosis when it comes to protecting the wildlife.

This practice is due to an agro-silvo-pastoral culture wich includes positive elements and is therefore difficult to condemn. Solutions can not be looked for without taking into account the subsistence requirements of those populations concerned.

The total wooded surface touched by fire annually is around 10 million hectares, which represents some.3 of the total world forested area. However the impact of these fires is more important than this small percentage suggests.

In fact, in the zones where the frequence of fires is high, the destructive character of such fires is worsened by the fact that forest stands do not have the time to reconstitute themselves between the passage eat of two consecutive fires.Â. An Integrated policy for the prevention and fighting of fires. The methods of fighting fires must be adapted to the socio-cultural environment in which they are put into place. Developed countries, developed countries possess the necessary materials to permit them to carry out a "No-fire" policy in order to satisfy public opinion, which is generally very sensitive to this form of threat to the natural environment. In this case, a perfect coordination between terrestrial and aerial fire fighting means must be provided, in addition to the active participation of the public and private forestry sectors, for example, in the participation of preventive operations and detective procedures.Â.

Against such freak winds forestry management has very little power. However, although foresters are unable to prevent such catastrophes, they have the power to limit the destruction of violent winds by favouring the development of stands that are more wind resistant, and by adopting a prudent and diverse outlook towards management. Periods of drought, water stress renders forestry stands very fragile. They can arise either by a change in the distribution of water throughout the seasons, for the same quantity of annual precipitation (the supply therefore being brought forward in relation to the demand of forest stands or by a fall in the annual volume. It has now been established that the numerous cases of dieback observed in forests supply stands throughout the world in the last ten years (which at the time were entirely blamed on atmospheric pollution) are due in part, to periodic water stress. In fact, those observations realised concern those forests in regions subjected to strong pollution fall out, but also forests of less affected regions. Biotic Threats, diseases and the attack of insects : brief overview of the situationÂ. Insects and fungi play an important part towards the causes of dieback in many forests of the world.Â. These biotic agents intervene, either as primary agressors, or most often as secondary agressors, often attacking already weakened stands.

future climatic changes, due to the consequences of green house gases from industrial pollution are going to grow. It is sufficient to study here not the ways of fighting these aggressions, but those measures to take before forestry stands are subjected to these events.Â. Forests are submitted more than any other terrestrial ecosystem to climatic hazards, due to the duration of their maturity, wich can take up to 200 years. In such a period the number of climatic hazards can be great. Storms and win-blow, storms have had an important destructive effect throughout this century, especially throughout the last twenty five years in Europe, destroying millions of m3 of wood, the following - 1990, almost 110 million m3 destroyed throughout Europe.â - 1999, 140 million.

But this classic division is a bit artificial, since man is partly responsible for all these threats. Indeed the mark of human actions is always present : it is however relatively moderate concerning climatic disorder despite the emissions of greenhouse gases, responsible for important destructions ;. These aggressions will therefore be classed by groups but keeping an effort essays to maintain classification by growing order of mans implications, and therefore the possibility of theoretical intervention will also increase. Agricultural purposes, grazing cattle or planting crops. Poor farmers in developing countries chop down a small area of trees and burn them, which provide nutrients for the soil (know as the 'slash-and-Burn' technique).
