Climate change is expected to have major impacts on the Australian grains industry, which is worth $7 billion annually. Although increases in atmospheric carbon dioxide (CO2) are expected to initially increase plant productivity, the realisation of these productivity benefits is expected to be limited by water and/or nutrient deficiencies. Given our low rainfall and infertile soils, there is considerable uncertainty about the applicability of overseas data used to model how Australian grain systems will respond to climate change (especially elevated CO2). This project will lead to better predictions of the impact of climate change on Australian grain systems so that appropriate adaptation responses can be developed by government and industry.

气候变化预计将对每年价值70亿美元的澳大利亚谷物行业产生重大影响。虽然大气二氧化碳(CO2)的增加最初预计会提高植物的生产力，但这些生产力好处的实现预计将受到水分和/或营养不足的限制。考虑到澳大利亚的低降雨量和贫瘠的土壤，用来模拟澳大利亚谷物系统如何应对气候变化(特别是二氧化碳升高)的海外数据的适用性存在相当大的不确定性。该项目将更好地预测气候变化对澳大利亚谷物系统的影响，以便政府和行业能够制定适当的适应措施。
