Specific Project Objectives and Deliverables

  • Mapping Agricultural Areas:
    • Land Cover: Mapping Frequency: Yearly, preferably around peak biomass (September).
    • Cropped Land: Mapping Frequency: As above.
    • Pasture/Rangeland: Mapping Frequency: As above.
  • Estimating Crop Areas
    • Statistical Units: field scale (ha)
  • Crop Growing Conditions Over the Growing Season (for 50 fields):
    • Daily tmin, tmax, precipitation, relative humidity, solar radiation, wind speed/direction (1 automatic weather station installed at site)
    • Vegetation reflectance (VIS/NIR) from UAV, LAI, phenology (on the ground, in-situ measurements) on a 10-day frequency
    • Non-destructive and destructive biomass measurements on a 10-day frequency

 

  • Estimation of Biophysical Variables (from satellite):
    • NDVI, LAI, fCover, fAPAR, biomass on a 10-day frequency

 

  • Phenological Events (from in-situ measurements):
    • Field preparation, sowing, emergence, juvenile, vegetative, flowering, grain filling, maturity, harvest, post-harvest dates / durations will be documented for each of the 50 fields monitored throughout the cropping season (see in-situ observations section below)
    • Information about crop development stresses (abiotic, biotic) will also be collected as part of the same field monitoring protocol

 

  • Integration of the EO-Derived Information Into Crop/Agro-Met Models / Forecasting Agricultural Variables from Crop/Agro-Met Models:
    • Data assimilation of LAI estimates will be explored in 2015 in hindcast (2014 data) and forecast (2015 data) modes. The crop/agro-met model to be used will likely be AQUACROP (subject to confirmation – other options are possible using the already locally calibrated, but more complex SarraH, APSIM and DSSAT models).
