Item Sugar Research and Development Corporation final report Project CTA013 Spatial analysis of the impact of land use on nutrient loads within the Herbert River Catchment(1998) Johnson, A; Walker, D; Wood, AThis Project arose out of concerns for the apparent increase in nutrient and sediment contaminant loads in Queensland coastal waters since European settlement (e.g. DEAP Report, 1992). At the time of Project inception, the origins of this increase had yet to be defined and quantified, however, the sugarcane industry was considered to be a likely contributor because of the large (and increasing) areas of sugarcane involved and the relatively high fertiliser inputs per unit area. There was, therefore, a need to develop practical tools to integrate existing information and spatially model, at the catchment scale, nutrient and sediment losses from agricultural land. It was the Project teams’ intention to provide tools to analyse important issues/questions relating to the sustainable management of existing and potential sugarcane lands of the Herbert River catchment. In response, four core areas of R&D were undertaken. These were: 1. Data collection and integration; 2. Spatial analysis of the impacts of land use and management practices on water quality; 3. Tools for decision support; and 4. Building stakeholder capacity.Item Workshop on new technologies in sugarcane crop forecasting : SRDC Final report WS004(2001) Wood, A; De Lai, RWork over the last 3 years in the Herbert Resource Information Centre has demonstrated that it is possible to use remotely sensed satellite imagery to produce a reasonably accurate crop forecast provided there is limited ground truthing to validate spectral signatures. In both the 1999 and 2000 harvest seasons, the estimates derived from the Landsat TM images were closer to the actual yield for the Herbert than the crop estimates derived from conventional methods. SRDC agreed to fund a project in the Herbert involving the HRIC and the University of Queensland to develop the technology further (project UQ037 Development of an a11- weather sugarcane crop yield model using satellite image data). The project was led by Mr Mark Noonan who was employed by the HRlC and was doing this work as part of a Masters degree at UQ. CRC Sugar also agreed to provide funding to assist Mr Noonan with his Masters project. Mr Noonan left the HRIC in November 2000 and arrangements have been made to complete the project through the university. The project is due for completion in June 2001. In the last year there has been a large amount of interest in this methodology from other mill areas such as Mossman, Mulgrave and Mackay and all sugar mills are searching for ways of producing accurate crop estimates without having to simd out large numbers of people to inspect every block of cane on every farm. QSL have also' expressed interest in this technology given the importance of accurate and timely estimates of sugar production for their operation. Initially the HRlC agreed to assist some of the mills in using the model, but with the departure ofMr Noonan this is no longer possible. Some mills (and QSL) are now approaching a variety of commercial companies to see whether they are able to perfect this methodology and customize it for their specific requirements. With the HRlC being placed under increasing pressure from different users to provide advice and expertise, and with the HRlC Board having decided that they should not get involved in research and development, CRC Sugar was requested to coordinate an industry workshop which focused on new technologies in sugarcane crop forecastin
