Cane supply options analysis for maximising whole industry profitability : SRDC Final report MSA001

Abstract

Opportunities exist for increasing industry profitability in the Mackay region through alternative cane supply schedules that exploit differences in CCS and cane yield at harvest date, found across the Mackay region and across individual paddocks on a farm. Research within CRC-Sugar Subprogram 3.2 produced the models needed to conduct options for alternative cane supply arrangements. With Mackay as a case study, and through participatory research with the Mackay Cane Supply Options Analysis Group (MCSOAG), key on-farm input data of CCS and cane yield response to harvest date and off-farm constraints in harvesting, transport and milling were developed for the model. Options analysis showed potential gains in profitability of $13M per year were possible in Mackay, without increased expenditure on capacity. Given an agreement for pilot implementation during harvest 2000, a pathway to implementation was developed through a process of workshops using action research. Some barriers to implementation were addressed, as well as a process that would lead to a further uptake after 2000. Eighteen harvesting groups and nine growers piloted alternative cane supplies in the 2000 harvest season, and while proof of concept was not established due to adverse conditions, piloting continued in 2001. Through evaluating the pilots of the 2000 harvest season, key learnings were incorporated to improve the process for 2001.
