Spatio-Temporal Detection of Land Use Land Cover Changes in Jalpaiguri District; Geospatial Analysis
Mallick Manika | Krishnaiah Y. V. [2]
Abstract: The incessant rise in population density has led to an escalating reliance on finite land resources, resulting in a transformation of land use and land cover patterns over the periods. For the sustainable development and management of land resources, continuous monitoring of land use and land cover has become a crucial aspect of research. Therefore, the objective of this study is to monitor changes in surface cover attributes in the sub-Himalayan district of Jalpaiguri from 2000 to 2020 using Remote Sensing and GIS. The analysis of LULC changes has used multi-spectral satellite data, including Landsat TM, Landsat ETM+, and Landsat OLI imagery for the years 2000, 2010, and 2020, to identify surface cover dynamics over the past two decades. Supervised and unsupervised classification of Landsat images was performed on 10-year time interval using maximum likelihood and K-Means method in the GIS platform. The generated classified layer demonstrates that between 2000 to 2020, a significant increasing trend has been observed in the classes of built-up area (140.39%) and tea plantation land (93.53%), while a sharp decline trend has been detected in water bodies (52.88%), sand deposition (53.46%), fallow land (32.76%) and agricultural land (18.57%) within the district. To validate the classified images, ground data and kappa coefficient analysis were employed, and the results showed overall accuracies of 0.85, 0.88, and 0.89 for the years 2000, 2010, and 2020, respectively. Finally, the satellite-based monitoring of land use and land cover changes with ground truth data, holds a significant importance for land use planning in this region to ensure sustainable land management in future.
