Abstract
The insensitive manner in which man is utilizing land in the modern era has necessitated a continuous examination of the changing land use pattern all over the world. This study uses geospatial technology to analyse the changing land use land cover pattern of Keecheri-Puzhakkal river basin in Thrissur district, Kerala from 1995 to 2020. The results of analysis revealed that from 1995 to 2020 built up land increased by 86.91 km², whereas the area under forests, paddy wetlands and water bodies declined by 9.32 km², 46.70 km² and 3.31 km² respectively. Area under mixed crops initially increased by 30.40 km² from 1995 to 2008 and then reduced by 52.72 km² from 2008 to 2020. NDVI analysis showed that from 1995 to 2020 land with dense vegetation declined from 36.11% to 14.10% of the total geographical area of the river basin and land without vegetation increased from 32.14% to 46.36% of the total geographical area of Keecheri-Puzhakkal river basin.
