[email protected] / 3 Abstract Demography is considered as the major influencing parameter for landuse and landcover (LULC) change. LULC dynamics is invariably associated with various forms of land and ecological degradation. Identification of drivers and mechanism of LULC dynamics is also crucial for alleviation of land degradation. This paper investigates the Issue Issue spatio-temporal dynamics of LULC and demography and their inter-relationship in the different administrative blocks located within parts of Subarnarekha watershed, Jharkhand state, India, which comprises a large 14 concentration of tribal population. The investigation was conducted in two successive time gradients i.e. 1987- 2000 and 2000-2013 corresponding to the pre- and post-state formation in order to assess the impact of urbanization on the LULC dynamics and demographic characteristics subsequent to the formation of the state. Three indices viz. Net Change Ratio, Annual Rate of Change and Single Index of Dynamic Extent were used to determine the spatio-temporal dynamics of five major LULC categories viz. builtup, builtup with vegetation, Volume Volume cropland, dense vegetation, and sparse vegetation with scrubs, while the demographic parameters used are namely Population Density, House Hold Density and percent Tribal Population.
