Natural Sequence Farming (NSF) is a rural landscape management technique
aimed at restoring natural water cycles that allow the land to flourish
despite drought conditions. NSF offers a low-cost, widely applicable method
of reducing drought severity and boosting productivity on Australia's farms
and landscapes. The technique is based on ecological principles, low input
requirements and natural cycling of water and nutrients to make the land
more resilient.

Andrews, Natural
Sequence Farming principles and the efforts to bring Peter's
techniques into mainstream use in Australia.
Over 30 years ago Peter, bought a run-down 2000 acre grazing property
called Tarwyn Park, near Bylong in the Upper Hunter Valley. He then
quietly set about testing the theories that he had been developing
virtually ever since he was a child, growing up on a station near
Broken Hill. By 1976 Peter Andrews claimed that the model he had set
up on Tarwyn Park was an example of a sustainable agricultural system.
Peter had recognized that the incised nature of most streams in Australia
was in fact accelerating the fertility decline of agricultural landscapes
(Figure 1). Stream incision meant that the increasing erosive energy
of water was leading to accelerated soil and nutrient loss, lowered
capacity for the floodplain to hold water and a loss of wetland habitat
within that valley. Stream incision had in fact lead to a total disruption
of the natural fertility cycle, leading to a chronic decline the overall
health of the landscape. He also observed that, under natural conditions,
the interaction between fluvial and biological processes would combine
to maximise the efficiency of nutrient and water use as well as carbon
cycling. He argued that this would actually lead to a growing of that
landscape as sedimentation would far exceed erosion and carbon sequestration
would far exceed carbon loss. Find out more of the story in 'Back from the Brink' available at most bookstores.
