Local Environmental Monitoring

• Environmental features monitored include
• Land Degradation
• Salinity
• Water Pollution
• De-forestation
• Many others

3
Local Environmental Monitoring

• Land Degradation
• Normally caused by an overuse (mining) of the
  land
• Poor cropping practice
• Over grazing
• Salinity
• Pests - Rabbits
• Weeds

Local Environmental Monitoring

• Land Degradation
• Remote sensing targets include
• Decrease in vegetation cover
• Increase in soil exposure
• Mapped using image classification
• Monitored using NDVI
• Weeds

Local Environmental Monitoring

• Salinity
• Caused by rising saline ground water
• Product of Australias climatic history
• Dryland salinity - due to tree clearing
• Irrigation salinity
