  • GIS application in Natural Resource Management

    1. 1. GIS application in Natural Resource Management<br />By:<br />Achal Gupta<br />
    2. 2. Introduction<br />Land is fundamental resource for almost all human uses<br />The use of land resources shaped by the interaction of two broad set of forces<br />Human needs ( socio- economic)<br />Environmental features and processes ( bio -physical)<br />
    3. 3. Natural resource are not uniformly distributed but vary spatially and, in consequence, the social and economic development challenges also vary spatially<br />Spatialbased Information is the base for natural resource management<br />
    4. 4. GIS<br />
    5. 5. Major application of GIS in NRM<br />Resource assessment<br />Change detection<br />Suitability analysis<br />Scenario study<br />Impact assessment etc.<br />
    6. 6. Watershed Management in Uttarakhand<br />Soil erosion<br />Siltation<br />Poor water harvesting<br />Abandonment of water harvesting schemes due to siltation and failure of harvesting of the designed runoff<br />Part of Uttarakhand<br />
    7. 7. Objectives<br />To quantify the amount of soil loss and sediment flow from the area given<br />To locate possible surface water harvesting areas using GIS<br />
    8. 8. Methodology<br />Soil<br />Digital Elevation model<br />Rainfall<br />Universal Soil Loss Equation (USLE) <br />Soil erosion<br />Normalized difference vegetative index<br />Sediment Yield<br />Overflow<br />Satellite imagery<br />Land use<br />streamflow<br />
    9. 9. Result<br />Three scenarios have been considered<br />Scenario 1 : No Soil conservation<br />Scenario 2 : Soil Conservation<br />Scenario 3 : Soil Conservation + tree Planting<br />
    10. 10. Spatial Distribution of Soil loss<br />
    11. 11. Spatial distribution of sediment flow<br />
    12. 12. Amount of soil lost<br />
    13. 13. Amount of sediment flow<br />
    14. 14. Amount of sediment fill in to dams per year (Ton/year)<br />The amount of sediment flows in to the dam will affect the amount of water available each year<br />This will affect productivity and livelihood of the community<br />
    15. 15. Delineation of Micro- Basins<br />
    16. 16. Delineation of Watershed<br />
    17. 17. Identification of suitable area for water harvest<br />
    18. 18. Identification of suitable area for water harvest<br />
    19. 19. Remarks<br />GIS is a powerful tool that can be used for NRM<br />Prior to setting development action, information on the resource is vital<br />Knowledge on the spatial dimensions could help to prioritize development actions and helps also to pursue policy makers<br />
