Abstract:
The present study examines the utilization of Geographical Information System and Remote Sensing in mapping
land use land cover modification in and around Gondar, Ethiopia between 1999 and 2017 therefore on notice and
analyzes the modification that has taken within the study area between these periods using satellite image
classification methodology. So as to attain these objectives, Satellite images of Landsat ETM+ for years 1999 and
2004 and Land sat OLI 8 for 2017 are obtained and processed using ArcGIS. The maximum likelihood formula of
supervised image classification has been accustomed to generate land use land cover maps. Land use land cover
classification, change map, has been done by using Arc GIS code. The modification results showed during 2004, the
areal extent of agricultural lands, settlements and bush/shrub lands have accrued to fifteen.74%, 24.03 and 25.66%,
respectively, whereas forest lands and barren lands areal extent has remittent to twenty seven.83% and 5.33%,
respectively. By the year 2017, the areal extent of bush/scrub lands accrued by 42.5%, followed by settlements
(25.46%) and barren lands (8.496%). The region extent of forest lands and agricultural lands was decreased to
10.03% and 13.37% respectively by the year 2017. Further, the modification results showed a continuous decline of
forest lands throughout the study period. The known causes for forest lands decrement were population pressure
and associated demands.
