An Insight to the Decadal Land Use Land Cover Changes of Dakshina Kannada District

Suman Kundapura | Usha Aswathaiah

Abstract: The Urbanisation has led to the rapid Land Use and Land Cover Changes (LULC) wherein, they are the most important indicators of changes in the ecosystem services. The LULC of an area reflects the pattern of human land use and plays a vital role in space soil and water conservation. The present study involves the statistical analysis to check the decadal dynamics in LC changes using LULC data for Dakshina Kannada district. The study also aims to spot the lost water bodies from the district. For the study most of the data is used from Bhuvan Indian Geo - platform of ISRO for the years 2005 - 2006, 2011 - 2012, 2015 - 2016. Totally 19 LULC classes were studied for the Dakshina Kannada district whose total geographical area is 4843 Sq. Km. QGIS an open source software, was used to extract the maps of the study area and map layouts were prepared. From the available data the study concludes that there is a typical increasing trend in the builtup urban, builtup mining and builtup rural with the rest of the LULC classes showing a decreasing trend. However, an unusual trend has been observed in the classes like forest, scrubforest, grass/grazing, barren/ unculturable/ waste lands and sandy areas. The developmental activities which took place in the past decade as the population of Dakshina Kannada district increased from 18, 97, 730 in 2001 to 2, 089, 649 in 2011 could be one of the reason for the sudden changes in the trends of LULC classes.
