Transcript

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