Research Proposal Summary

Seasonal climate predictors such as the Southern Oscillation Index (SOI) and Sea Surface Temperatures (SST) at a given point in time offer the potential to predict future climate, say over the next 3, 6 or 12 months.  Considerable international research on climatology is continually improving the skill and reliability of these future climate forecasts.  Can the Australian Sugar Industry benefit from seasonal climate forecasting?  For example, can the SOI in September be used to predict the rainfall over the next 6 months so as to guide decisions on irrigation management where water is limited ie should irrigation water be conserved until after Christmas for the "boom" period of growth or should water be used before Christmas to ensure good ratooning and rapid canopy development.  Seasonal climate prediction could also benefit decision-making relating to yield forecasting, harvest scheduling and marketing.  In considering marketing, not only could climate predictors be used in relation to Australian production but also in forecasting production in overseas countries.

The important question however, is how useful are climate predictors in forecasting future rainfall and production for different locations in the Australian Sugar Industry, and of prediction production by our overseas competitors.  Research has shown that seasonal climate forecasting has the potential to benefit risk management and decision-making in the dryland cereal industries of Australia, but no evaluation has been made for the Australian Sugar Industry.  This project aims to evaluate and increase awareness of the value of seasonal climate forecasting for the Australian Sugar Industry.  Applications related to irrigation management, yield forecasting and sugar marketing are considered in this proposal.

The Australian sugar industry operates in an uncertain and highly variable climatic environment.  Skill in objectively derived seasonal forecast systems offers the potential for better decision within this environment.  Climate forecasting can assist on-farm decision on how to use scarce and/or costly water supplies, which is of high strategic importance to future industry productivity.  In addition, skill in climate forecasting offers the potential to improve profitability at the mill scale and improve international competitiveness at the industry scale.  At the mill scale forward estimates of crop size in each mill district are used to determine harvest season length and crush start and finish dates.  Greater precision in these estimates will lead to improved profitability through both enhance on-farm profitability and better utilisation of milling capacity and industry assets.  At the Industry level, forecasts of sugar production both in Australia and overseas-producing countries over a range of time frames are extremely important in the marketing of sugar to ensure maximum export earnings.  An industry workshop jointly funded by SRDC and LWRRDC recently held in Mackay (2/8/96 R&D Workshop) on applying seasonal climate forecasts in the sugar industry) established a clear requirement for application of seasonal climate forecasts directly to the sugar industry.  At this workshop it was demonstrated from APSRU/QDPI/CSIRO research that seasonal climate forecasting already offers the potential to increase profit and reduce risk to the cereal industry in north-east Australia.  However, these systems have not yet been applied to the sugar industry where similar improvements to profitability and risk management would be highly likely.

Aims

§    To provide improved risk management and decision making capability for the Australian Sugar Industry through effective integration of seasonal climate forecasting with strategies for:

o            The use of limited irrigation supplies

o            Yield forecasting and harvest scheduling

o            Sugar marketing

§    To increase awareness of the value of seasonal climate forecasting for the sugar industry and examine the feasibility of different mechanisms for delivery of information that will enhance the capability of growers, millers and marketeers to use seasonal forecasting in management decisions.

Potential Outcomes

§    Improved on-farm management by better use of scarce water resources, increased water use efficiency and higher sugar production

§    Improved scheduling of mill start and ending dates leading to more effective use of resources eg. Milling capacity, haulage equipment, shipping together with enhanced on-farm profitability

§    Enhanced industry competitiveness through more effective forward selling of sugar and improved efficiency of sugar shipments

§    Industry awareness of the potential role of seasonal climate forecasting in improving decision-making at different points in the industry value chain

Relevance to Strategic Plan

This project addresses the following strategies:

§    work with farmers and their advisers to explore options using simulation models, simulation analyses, or derived tools

§    work with clients to explore how they can use/benefit from skills in climate forecasting
