MEANING OF SUSTAINABILITY IN AGRICULTURE
This section is specifically concerned with gaining a better understanding as to the meaning of sustainability in
agriculture, which is a maze of complexity and can be open to wide interpretation. Throughout history farmers
have striven to maintain the productivity and fertility in their soil [Fagan, 1974]. Over the last twenty years
Australian farmers have become increasingly aware of the need to adopt more sustainable agricultural systems and
there has been an increased emphasis placed on the term "sustainable agriculture" [Campbell, 1991]. This has
coincided with a proliferation of literature and theories on this topic, leading to numerous and often confusing
concepts, as well as many contentious interpretations of the meaning of sustainability [UNE, 1992]. It should be
noted from the outset that there is no simple definition for sustainability in agriculture, rather there are
numerous definitions and paradigms, which are sometimes conflicting [eds Edwards et al. 1990]. The theories
presented are therefore only tentative and are subject to the criteria being used to form the definition.
The search for the meaning of sustainability, as previously discussed, is complex to the point where Campbell
 believes that a precise definition remains elusive. As stated previously Campbell  holds that
most of Australian farming systems are unsustainable by any definition. Roberts  regrets that there
is unfortunately no clear definition of sustainability in agriculture. This lack of a precise definition has
left a void of uncertainty or confusion, causing wide interpretations of the meaning and use of the term.
The initial problem therefore is to develop an understanding of the meaning of sustainability in agriculture,
which has a wide range of perspectives and shades of meaning. According to Campbell 
"a sustainable farming system is one which is profitable and maintains the productive capacity of the
land while minimising energy and resource use and optimising recycling of matter and nutrients" [Campbell, 1994, p.4].
Roberts defines sustainable agriculture as
"a system which maintains the productive capacity of the land and its economic viability.
It minimises energy and resource use and optimises the rate of turnover and recycling of organic matter
and nutrients" [Roberts, 1995, p.225].
Campbell  adds to the debate over sustainability and asks the question, is sustainability concerned with
"how to safeguard nature's productive capacity to support human existence in a way which best fits
the lifestyle aspirations of current generations" [Campbell,1994, p.278].
Conway  takes an inductive and narrower view of sustainability in regard to agroecosystems and recognises
it as part of an analytical framework to evaluate performance along with stability, equitability and productivity
being considered as the criteria. Campbell  recognises Conway's  narrower definition of sustainability
as "the ability of the system to maintain productivity in spite of a major disturbance such as a large stress
[eg salinity, indebtedness] or a large perturbation [drought, flood, disease, a new pest]" [Campbell,1994, p.174].
This author does not wish to add a further definition, but would suggest that in relation to Australian sustainable
agriculture there are a number of accepted principles and they include: profitability, maintenance of productivity,
minimising energy and resource usage and recycling of organic matter and nutrients [Campbell, 1991; Roberts, 1995].
