Forests cover about 40% of the earth’s
surface. To this, tropical humid forest constitutes 60 million hectares.
The lower
altitudes of the Mount Cameroon Region undergo radical changes in forest cover.
These changes are linked to the creation of vast plantations of the CDC, the
opening of new crop farms and other cash crops such as cocoa and the extension
of settlements. Besides these, volcanic eruptions which have a frequency of at
least 1 time in every 11 years also induce major changes mostly on the forest
cover. These changes thus constitute a preoccupation of the Cameroonian
Government to interrogate on the factors and the rate of these modifications.
The rate of
deforestation is analysed in terms of biodiversity destruction and the danger
that lava flow poses during volcanic eruptions. This study emphasizes on the
evolution of deforestation between 1986 and 2000, done through Remote Sensing.
The study with the results realised tries to throw more light on the
quantitative change mentioned above. The work demonstrates the extent of forest
degradation which is in an irrational manner and which; given the demographic
growth, risks becoming irreversible if conservative measure are not reinforced.
