5.3 Surroundings of the refugee camps; 
The original vegetation (savannah and forest gallery) inside and around camps, within 
a radius of 2km from the camps, have been clear felled. The damages decrease further 
away and the limits between two levels of deforestation become diffuse. 
6.CONCLUSION: 
It is difficult to distinguish at smaller resolution of (30m*30m) of an image in this 
regard a large scale aerial photo interpretation remain the best technique. It is 
impossible to characterise the vegetation types masked by bush fire. In this case black 
and white aerial photographs are useful. 
Field checking may be required to validate more of this types of interpretation. The 
tools used in this exercise are of greater importance in determining of intervention in 
land degradation necessary such as refugee influx.
