CHANGING PHENOMENON OF AQUACULTURE LAND THROUGH SPACE AND TIME USING GEOINFORMATICS TECHNIQUES: A CASE STUDY OF MOYNAAND NANDAKUMAR BLOCK, PURBA MEDINIPUR, WEST BENGAL, INDIA

Abstract

Aquaculture basically known as aqua farming that means the farming of aquatic organisms such as fish. This can be considered a sustainable land use in the same way as like the conventional terrestrial agriculture. It involves with raising fish commercially in tanks, ponds which is mainly for nutrition. Which is a highly regulated industry, and these regulations may well keep fish farming. Numbers of peoples are becoming dependent on the aquaculture system. Fundamentally, agricultural land provides space and opportunities for livelihood systems, however in many ways peoples are over- exploited land and water resources. In the present study an attempt has been made to identification and quantification of aquaculture zone occurring in the inland area of Moyna and Nandakumar Block, Purba Medinipur, West Bengal, India by using space-born Remote Sensing (RS) technology, which has a good potentiality for change detection and good data availability and is consequently; well suited for the monitoring of land use change over a gap time period. The benefits of Geographic Information Systems (GIS) application in aquaculture have promoted its quick expansion and as a most advantage to compare with the ground reality. The present study describes an efficient and scientific approach for aquaculture changing phenomenon with suitable illustrations of map to point out insight the respect of ground reality. The aquaculture area is delineated from satellite images through image processing technique and aquaculture zone are specially highlighted from spatially high resolution satellite images. Finally the study can shows that, the agriculture lands are highly vulnerable due to regular flooding and that land specially converted to aquaculture land. This in turn
