Analysis of Land Use and Land Cover Dynamics Using Geospatial Techniques: A Case Study of Pasighat Circle, East Siang District, Arunachal Pradesh

Marina Langkam, Tage Rupa Sora

Abstract: The global landscape has been changing over the years with the changes in land use and land cover (LULC). LULC change analysis enables us to understand which LULC class is changing to the other over time. Such information is necessary for effective utilization of land resources. The paper aims at analysing the changes in land use and land cover classes of Pasighat circle of East Siang district, Arunachal Pradesh from 2001 to 2021. The study has been done using remote sensing and GIS (Geographic Information System) techniques as these are the most efficient and effective ways of analysing LULC changes within a short temporal period. Landsat images of 2001 and 2021 were used to prepare the LULC maps of the respective years. Data processing and analysis have been done in Arc GIS 10.8 software. Onscreen visual image interpretation method has been used* to classify the study area into six LULC classes namely Agriculture Land, Built - up Land, Vegetation, Sand, Open Land and Water bodies. The change analysis shows that there is a significant increase in built - up land (205.33 %), and agriculture land (22.46 %) while a negative change in area can be seen in vegetation (16.38 %). Negligible change is observed among the LULC classes of sand, open land and water bodies during the period of study.
