a visual regime

I realised that my low key approach to the local Fleurieu  landscape has been one of immersion or absorption within  the remnant scrub. An example of this kind of crafting of the image:

This is at odds with the detached, disembodied  neutral observer with an objective and ahistorical vision--what is known as Cartesian perspectivalism----which  has been  common  in, or central to,  mainstream photographic discourse.   This perspectvalism or visual regime combines the Renaissance notions of perspective with  the  Cartesian ideas of a disembodied,  subjective rationality in which the eye and its gaze are foundationally allied with transparency,  operating as the abstract vanishing point of Renaissance perspective.  Subjective rationality underpins photography.  

degraded agricultural landscapes

Sadly,  a lot  of Australia's agricultural landscapes are in the grip of a slow death. It's not just the clear felling of the woodlands  or the   loss of life, that is species (plants and animals) extinction either.  There is also drastic loss in life support systems.  

The plagues of rabbits (introduced to the continent with the first fleet) invaded the rangelands, eating all the vegetation and leaving the soils exposed to wind and rain. Overgrazing by cattle and sheep, particularly during periods of drought, exacerbated problems; in areas where rabbits never flourished, cattle seem to have been equally effective in denuding the country.

 Much of the one quarter of Australia that is not rangelands is being intensively farmed. There is salinity, in many places, and acidity in others, both of which are devastating this farm land.
