Towards farming-systems change from value-chain optimisation in the Australian sugar industry AgEcon
Antony, George; Prestwidge, D.; Sandell, G.; Archer, A.; Thorburn, Peter; Higgins, Andrew J..
The supply chain of the conventional Australian sugar industry is characterized by horizontal separation between the stages. Often antagonistic relations between segments, particularly farmers and millers, led to each developing their systems for their own segment’s benefit, without reference to the wider industry interests. Cane growing developed into a monoculture, reliant on material inputs and technological solutions, whose low labour intensity afforded substantial lifestyle benefits to growers. Such a system worked well while the industry was the worldwide cost leader, but it has contributed to stagnating yields and left growers exposed to the industry downturn caused by Brazilian competition. Over the past few years, CSIRO and BSES research aimed at...

Optimisation and the selection of conservation contracts AgEcon
Hajkowicz, Stefan; Higgins, Andrew J.; Williams, Kristen; Faith, Daniel P.; Burton, Michael P..
This paper explores alternative techniques for the selection of conservation contracts under competitive tendering programs. Under these programs, purchasing decisions are often based on the benefits score and cost for proposed projects. The optimisation problem is to maximise the aggregate benefits without exceeding the budget. Because the budget rarely permits all projects to be funded, there is a binary choice problem, known in the operations research published work as a knapsack problem. The decision-maker must choose which projects are funded and which are not. Under some circumstances, the knapsack problem can be unsolvable because computational complexity increases exponentially with the number of projects. This paper explores the use of several...

IMPROVING COMPETITIVENESS OF THE AUSTRALIAN SUGAR INDUSTRY BY ANALYSING CANE SUPPLY ARRANGEMENTS ACROSS THE VALUE CHAIN AgEcon
Brennan, Lisa E.; Muchow, Russell C.; Wegener, Malcolm K.; Higgins, Andrew J..
The term “value chain” describes the collection of activities that are performed to design, produce, market, deliver and support a product. The Australian sugar industry value chain has a number of distinct stages involved in the transformation of the cane crop into raw and refined sugar and other manufactured products. These stages include production, processing and distribution functions. Despite its linear direction, a critically important feature of the sugar industry value chain is that it is not a collection of independent activities but a system of interdependent activities. In the Australian sugar industry, there remains a significant degree of segregation in the organisation of growing, milling, and marketing activities, despite the fact that...
