Abstract
The coastal environment is a unique and dynamic system where elements from land, sea, air and people converge and they are unique in a very real economic sense as sites for port and harbour facilities that capture the large monetary benefits associated with waterborne commerce. The present study is carried out in Vizhinjam Panchayath, a coastal area located in Thiruvananthapuram, Kerala and has a natural harbour surrounded on most sides by land which is going to develop into an International Seaport. In this study, an attempt has been made to analyze the changed land use pattern of the proposed harbour area during 2009-2014. The study uses IRS-LISS- IV, Cartosat data and Arc GIS software. The study has observed that the built up activities have been increased by 8.8% during 2009-2014 whereas agriculture in the area showed negative growth with a net decrease of 6.4%. The results of the study underscore the fact that the future harbour developmental activities and their operations need more land and it has chances of negatively affecting the land use pattern of the study area.
