Local Expert Analysis (LEA): an objective approach to identifying constraints and opportunities

Science is based on the objective analysis of data where conclusions need to be supported by the prevailing evidence. Scientists are thus trained to consider the facts and to draw sound conclusions. Those trained in specific disciplines use their skills-based experience to bring understanding to the issues being investigated. Some regions in the Australian sugarcane industry are suffering lower than expected productivity and profitability. A Local Expert Analysis (LEA) engaged SRA scientists from different disciplines and industry staff to analyse industry data in order to determine the reasons for the lower-than-expected productivity. Local industry organisations, farmers and millers, have contributed to the process by working collaboratively to identify both constraints and opportunities to improve both farm and Mill viability. The South Johnstone LEA has highlighted that several diseases, crop nutrition and other agronomic factors have been limiting yield. Opportunities identified include refined harvesting operations/sterilisation, optimised variety selection at the farm level and better data collection and analyses. Economic analyses and modelling will provide guidance on how both farmers and the miller can ensure future economic viability.
