| Abstract: |
Land use and land cover change has immense impact on the global environment
and ecosystem. Geospatial technologies are very important for monitoring these
changes. This research aims to find out the land use land cover dynamics and drivers
of Ambung VDC, Tehrathum district. The Landsat images of the year 1990 and 2013
were used for quantifying the changes. Household survey, key informant interview,
focus group discussion, training samples collection and direct field observations
were carried out to gather socio-economic and bio-physical data. Supervised
classification was performed to prepare land cover maps. Change on land use was
calculated by using post classification change detection. During 1990–2013, forest
cover was found to have increased by 6.6%, agriculture decreased by 5.9% and
others (barren, settlement, grass, rock and water bodies) decreased by 0.7%. The
VDC was found to have severe problem of rapid drying of water resources in spite
of the increase in forest cover, and so research should be carried out to find out the
reason and solve the problem before it is too late. |
