Nadia district of West Bengal, India has very special characteristics in land use/ land cover dynamics due to its long international boundary with Bangladesh and proximity to Kolkata city. In this study, satellite remote sensing and GIS technology has been used to measure the curves and shifts of land use/ land cover change in Nadia district over a time period of more than three decades. Landsat MSS data of year 1972, TM data of 1989 and ETM+ data of 2006 have been used for this purpose. Four prime land use classes have been adopted for supervised classification following maximum likelihood classification technique of images. Results revealed a huge increase of settlement during 1972 to 2006 and subsequent decrease of natural vegetation cover mainly due to high illegal immigration from Bangladesh. Increase in numbers of people working at Kolkata but living in Nadia district with much cheaper lifestyle is the other factor. In comparison to settlement growth, only minor initial increase and then decrease of land under agricultural practice indicates a high rate of urbanization.
