Development of Decision Support Information System for Management of Waterlogging and Soil Salinity using Geospatial Technology

The present study areas mostly were under artificial irrigation system, therefore, the problem of waterlogging and soil salinity rapidly increasing day by day. The present research found that the area under seasonal waterlogged is 17.95 sq. km. (2.37%) and the area under the permanent waterlogged category is 5.42 sq. km. (0.56%) of the study area. As per the findings of salt-affected soil sample analysis, the 4.8% land of total geographical area (TGA) is affected by salt. Out of which the saline soil covers 52.45% and saline-sodic covers 45.54% of the total salt-affected area respectably. The central and western part of area was most affected by above said problem. The major aim of the study to avoid problems of waterlogging and soil salinity using geospatial technology with management and development of decision-support information system for such valuable land resources as recommended a comprehensive and sustainable plan to be worked out that includes, plantation of deep-rooted trees, maximization of net returns of field crops including cereals pulses, oilseeds, timber and fodder, orchards and social forestry species of dry deciduous plants, pastoral development, reduction of water allowance. Further, a proper drainage method and selection of suitable cropping pattern was suggested that requires lesser application of water can reduce the percolation of water reaching the groundwater table and screening the tolerant plant for waterlogged introduces and green the waterlogged soils are also helpful to reclaim these affected lands.
