In this period 10.38% land use land cover transformations were noticed for the whole study area. 82% vegetation area was transformed into other categories. Its 49.3% area transferred to agricultural land, 16.4% to a sandy area, 15% to Satluj River, 0.41% to a built-up area, 0.36% to water bodies and 0.23% to barren land. A noticeable change was detected in the sandy area. 80.63% sandy area transformed to other categories, whereas 36.64% area added to this category from others. It gained 36.64% share of Satluj River, 16.4% of vegetation, 0.27% of agricultural land, 0.06% of built-up area and 0.01% of forest area, while land previously under sandy area got transferred to other categories, which included 47.82% to agricultural land, 17.7% to vegetation cover, 14.51% to Satluj River, 0.6% to built-up area and 0.01% to wetland. More than half i.e. 56% of Satluj River channel area was transformed to other categories with a prominent share i.e. 37% going to the sandy area, 15% to agricultural land, 5% to vegetation, 0.1% to wetland, 0.05% to barren land, 0.01% to forest and built up area. This category was expanded by 136.98 ha (9%).

During this period 15% of vegetation cover, 14.5% of the sandy area and 0.25% of agricultural land were submerged under the Satluj River channel (Table 3.7 and Fig. 3.13). 54% built-up area was transferred with its 53.71% part was encroached by agricultural land, 0.2% by wetland, 0.1% by vegetation and barren land, 0.06% by sandy area and 0.01% by forest. Built up area was expanded by 151.33 ha (3.98%). This category benefited by 2.37% of agricultural land, 0.6% of the sandy area, 0.41% of vegetation, 0.18% of wetland, 0.05% of forest and 0.01% of Satluj River. Wetland area decreased by 14.43 and 48% of its area was transferred to other categories, which includes 47% to agricultural land, 1% to vegetation, 0.2% to the built-up area and 0.01% to forest cover. Water bodies faced 11.57% spatial reduction from 102.2 ha in 2000 to 90.37 ha in 2005 with 32% transformation to other categories. Its 24.5% share went to vegetation, 7% to agriculture and 0.04% to Satluj River (Table 3.7 and Fig. 3.13). Reserved and protected forest area faced only 6% transformation due to the Government implemented restriction. The agricultural area with 1353.04 ha increase attributed by the 53.71% share contribution of the built-up area, 49.3% of vegetation cover, 47.82% of the sandy area, 47.36% of wetland, 14.74% of Satluj River, 7.1% of water bodies and 6.1% of forest area. Agricultural area faced about 4% transformation for other categories. Its 2.37% share went to built-up area, 1% to vegetation, 0.
