Abstract

Urban regions are currently developing and growing more quickly throughout the planet. Urban expansion has a major impact on the dynamics of land cover (LULC), which frequently leads to important changes in the environment and the socioeconomic system. This study examines how urban growth affects LULC in Pudusserri Grama Panchayat, which is situated in the Palakkad Gap. Through the study of satellite imagery and GIS data from various periods, the research finds patterns and trends in land conversion, highlighting the encroachment on agricultural land, deforestation, and the rise of built-up places. The study stresses how important sustainable urban planning is to lessen adverse effects on the community and local ecosystem. This study provides a thorough chronological and spatial analysis, which helps policymakers combine development with environmental conservation.

Supervised categorization was used to create growth in the built-up area. Between 2001 and 2021, the study area's built-up area grew from 430.65 hectares to 1002.01 hectares. The entire geographical area in 2001 was 6784.3 hectares, of which 430.65 hectares were built-up land and the remaining 6353.65 hectares were noted as non-built-up area. The built-up area shares 1002.01 hectares in 2021, while the non-built-up area contributes 5782.9 hectares, as the geographical area did not change during the study period. The outcome of the study was that agriculture had shown a tremendous decrease from the period 2001 to 2021. Most of the agricultural area was converted to build-up land. The built-up land had been increased. In the period 2001, it was only 430.65 hectares but there was a tremendous increase in the period 2021. Vegetation has been increased in the period 2001- 2021. Wasteland and water bodies had a tremendous decrease in the period 2001-2021.
