The originally identified land use categöries with their 
known vegetation characteristics are identifiable on the 
radar and satellite imagery respectively. By means of 
detailed and systematic ground truth investigations, it is 
hoped to confirm whether the findings in the study areas 
can be applied to larger areas which exhibit similar image 
characteristics. 
The use of multi-date remote sensing imagery will indicate 
trends in wood productivity in the fuelwood hinterland of Kano 
which, in comparison with present consumption estimates, 
will allow an objective assessment to be made of bhe 
potential impact on the savanna ecosystem of the continued 
use of fuelwood as the main source of rural energy,
