Abstract: 

‘Land use and land cover change’ is a dynamic process, its magnitude and direction of change is highly vulnerable to human actions. Human beings are the core agent that promotes this dynamic landscape transformation. These conversions occurred due to the expansion of human employment on land at the cost of natural cover, which simultaneously faced disappearance. This journey of landscape transformation includes expansion and disappearance of land use and land cover categories with reference to different points in time. In Punjab Satluj floodplain this changing transformations can be noticed from the changing land cover to land use ratios, which was 54:46 during 1975 and reduced to 12:88 for 1989 and this pattern continued for succeeding years with 8:92, 7:93 and 5:95 for 2000, 2005 and 2012 respectively. Land cover categories lost their land, whereas land use categories gained it. This gain loss algorithm highlights the need of setting the threshold limit of land use and land cover transformations
