GIS application in UP Bhumi Sudhar Nigam Presented by : Prabhu.R 20071120

Purpose of study:

Purpose of study UP has about 1.29 million hectares (ha) land affected mainly due to water-induced land degradation (salinization, sodification, groundwater depletion) and loss of soil fertility with the sustained removal of nutrients associated with more intensive cropping and inappropriate use of nitrogenous fertilizers. UP Bhumi Sudhar Nigam (UPBSN) has undertaken UP Lands Reclamation Project with the financial assistance from the World Bank This project is being implemented in 15 districts of UP, where the soil is severely affected by high salt concentration .

Study Area:

Study Area Allahabad, Aligarh, Etah, Etawah, Fatehpur, Hardoi, Mainpuri, Pratapgarh, Raebareli, Sultanpur, Kanpur, Unnao, Jaunpur , Azamgarh and Buland Sahar

GIS Application:

GIS Application Cadastral level : Initial map contains the Village road, metal road, plot boundaries etc. Advanced equipments are used in these villages to obtain location of main drains, link drains, tank, culvert/ bridge, slope etc. Taking few common points on base map, entire surveyed data is super imposed on it. Keeping in view of ridge and valley line drainage and irrigation network is planed and considering slope aspect boring sites are proposed at higher elevation.

Continued :

Continued Many other parameters like depth and thickness of available acquifer, water table, water quality, fluctuation of water table and EC etc. are also consider for the selection of boring sites. Now the plan map of a village is ready for execution. Upto this stage total process is taken care by GIS and its Associate packages. On the other side village base line, plot details and progressive data of these villages, already stored, will regularly be updated in Management Information System (MIS).

Continue :

Continue Topographical Level: Topo-sheet maps of all the districts 1:50,00 Scale has been digitized. At each project district, which contains an average 15,000 ha of Sodic area, villages have been selected for reclamation in different years. In order to monitor ground water level in the sites 45-50 observation wells have been identified besides 5 to 10 peizometers /site. Pre and post monsoon water level measurements are recorded from these observation well. On the basis of water level data obtained from these hydrographic station, pre and post monsoon water level contour are being generated.

Slide 7:

Zonation of depth to water is helping in identifying shallow and deep water table areas, which is being used for demarcating areas for intercepting drain and suitable areas for horticulture

Presently utility of GIS/RS is being used in following activities:

Presently utility of GIS/RS is being used in following activities To identify location of specific village/area of interest, which satisfy suitable conditions for selection, based on specific parameters. pre and post monsoon water level and fluctuation data; below ground level as well as with respect to mean sea level for defining spring level and flow direction.

Map Showing Land Use in Raebareli District :

Map Showing Land Use in Raebareli District Loose or close coupling with GIS of simulation models of salt movement in the soil profile and ground water column. Zonation of Depth of Ground water and delineation of shallow water table area. IRS LISS II/LISS III based project durability evaluation and integration with GIS. Evaluation of land use changes, soil quality, GW level and quality reclamation over a period of time. To locate suitable boring site and pumpset installation. To existing drainage and canal status and future planning to drainage development. To identify the catchement area of a drain. Integration of spatial and non-spatial data

Some Issues:

Some Issues Presently source maps (cadastral)on 1:4000, are being used, supplied by Dept. of Revenue. These maps are very old and have no projection system. UP RSAC has taken some initiative in this direction. Procurement of GPS under process which will be used to transfer cadastral level information to 1:5,000 scale map.

Conclusion :

Conclusion Under the on going U.P. Sodic Land Project, Environmental Monitoring data can be integrated on GIS platform for analysis and Evaluation of sustainbility of reclamation Selection of project villages ,post reclamation monitoring and behavioral changes in Ground Water levels and quality .
