AbstractGIS Application for Tea Plantation Problems of North-Eastern India Track: Agriculture Author(s): Rajib Bhagat, Dibyajit Buragohain, Kumar Bordoloi, Mridul Hazarika, Rishi Dutta While waterlogging is a limiting factor for tea gardens of Bramhaputra plains, soil erosion and landslides are the major problems in the hilly tea plantations of Darjeeling and Barak valley of North-Eastern India. Considering the differences in the nature and extent of soil and water management problems, five major river basins in North Eastern India were selected. Satellite imageries of multiple dates (IRS 1D, LISSIII) between 2004 and 2005 were used. The satellite data were geo-referenced and suitable image enhancement was applied for the delineation and interpretation of different thematic information. Blocking of drainage system, eutrophication of waterways and unplanned extension of tea gardens was the major cause of waterlogging, while denudation of forest areas in upper catchment, loss of grass cover and road construction was responsible for erosion and landslides. Detailed solutions for drainage, erosion and landslides control were suggested.
