Abstract
This study assessed land use! land cover change of Finchao valley area by integrating GIS
and Remote sensing rechniques in Finchaa valley area in belll'een 1973 and 2003, The stud,'
comparedfollr different techniques: image differencing, rationing NDV! image comparisons
and posl classification Comparisons, Image differencing and rationing proved not suitable
fiJr Ihe slwl\' area, SDVI isfollnd belter for visual comparisons with its mean \'{Ilues, Posl
classification comparison is proved the best melhodfor Ihe stlldv area,
The res lilt of Ihe analysis indicates thai generally \'egetalion cove is decreasing a/lribule ta
increase in crop land with accelerated rate of change, Ihe de\'elopment of mechanized slate
farm in heMeen 197_' and 1986 and agroindusrial development since! 991 at accelerated rate
of change "'ilh ils re 'ated inji'astruclures bUI collapse of slale f arm in the valley. The change
is directly related to socia-economic activities, fire and poor elIvironl11enlalll1anagell1ent and
inseparably connect"d to one ana/her, From observational the change has negative
implications on the environments particularly all land, vegetation and animal diversities,
Therefore the ill environmental management strategy should be re evaluated fO pro/eel 10
