Natural Sequence Farming
Natural Sequence Farming is a method of landscape regeneration devised by the Australian agricultural pioneer, Peter Andrews, in the 1970s. From the 1970s till the mid-2000s, Natural Sequence Farming was ignored and rejected by many farmers, the agriculture industry and local, state and federal governments, but these bodies have since come full circle and today NSF is recognised as a viable solution to environmental regeneration.
The method involves implementing major earthworks on a given area of land that has been devastated by deforestation and general agricultural activities, to emulate the role of natural watercourses in an effort to reverse salinity, slow erosion and increase soil and water quality to enable native vegetation to regenerate and restore the riparian zone.
The method does not require the use of artificial fertilisers or herbicides.
==Flood control==
Flood events may occur only once every 1 or 2 years, however they have the ability to enhance or destroy a property. If the waters move too fast over bare land, then they can strip away topsoil and nutrients, leaving behind barren sands. By inserting barriers across creeks and encouraging water to spread outwards, the energy of a flood is reduced, waters tend to deposit soil from upstream, and the water can soak into the land. This encourages grasses and fast growing plants to take root.
