The Indo-Gangetic Plain is a rich, fertile and ancient land encompassing most of Northern and Eastern India where, land use particularly agriculture has undergone dramatic changes in the last four decades. Of late evidence is accumulating to suggest that high productivity and growth rates achieved during the Green Revolution era are no longer being sustained to meet the needs of still increasing population in the region.
There has been effort to search for unattended regions to scale up the agricultural productivity to meet these needs. Keeping this in view, an attempt was made to undertake land use land cover change analysis over two decade and evaluate different land use particularly agriculture and its change with respect to its spatially varying biophysical parameters such as topography, land form, soil, weather, water resources of the regions.
Land use cover change analysis was done using multitemporal satellite data of 1km and 8km resolution available in public domain. Spatially varying land forms and topography of the region were derived from DEM data of GTOPO30 available at 1km resolution. Information on soil and water resources (i.e. irrigation area) was taken from available soil map of FAO and IWMI respectively.
Study was carried out to correlate major land use land cover classes and their changes with these parameters in GIS environment having main focus in agricultural land use pattern. This would form a frame work to predict possible land use type or change in land use based on single or composite effect of these biophysical parameters at regional scale.
