Ms Sofanit Araya
  • Biography/ Background

    Sofanit is a PhD candidate in the spatial information Group, Landscape Science, School of Earth and Environmental Sciences, The University of Adelaide. Her PhD research is with the upholding title :

    "Digital soil mapping for sustainable agricultural productivity"

    The understanding of spatial and temporal yield variability is the key for better management of agricultural fields. The crop yield in arid and semi arid environment is highly dependent on the water availability. Vegetation condition is a good indicator of the soil and its interaction with the environmental factors such as rainfall. Time series analysis of MODIS imagery has been widely used for various agricultural related studies such as crop identification and yield estimation. However it hasn't been widely used for the understanding of the soil conditions underneath.

    Her project aims to study the soil condition (Water Holding Capacity) in terms of agricultural productivity using time series spatial information.
