nly go so far
when it comes to prediction or automated mapping of gully
occurrence. These difficulties arise from the variability in
factors that contribute to gully occurrence; the complex shapes,
size and forms of gullies; and the lack of access or ability to
obtain additional high-resolution data that might be useful, such
as grazing pressure or high resolution soil maps. Considering
the current limitations the best approach would be to invest
more time and efforts in hands-on, pragmatic approaches based
on observations and field data rather than predictive modelling,
which could be used as a last option to fill gaps at locations of
low certainty.
