![]() “Gross margin budgets were used to estimate individual crop profitability under any change in variability under both recent climatic conditions and the 2030 climate scenario,” Ms Scott said.Ī long-term average price of $190 a tonne was used. Simulations based on a historical benchmark climate period between 19 and projections for 2030 were conducted for sorghum, using a Global Climate Model CSIRO Mk 3.5-A2 scenario.īy 2030, CSIRO Mk 3.5 predicts maximum and minimum temperatures will rise between 1.6C and 1.7C and rainfall will decrease by 10 to 11 per cent at Moree. The climate of northern NSW by 2030 is likely to be warmer and drier. “The strategies tested include variations to crop residues at sowing, plant population, row configuration, sowing time and variety maturity.” “APSIM has also explored methods for managing current climate variability,” said Fiona Scott, a NSW Department of Primary Industries (DPI) economist at Tamworth. The cropping model Agricultural Production Systems Simulator (APSIM) has offered some insight into the performance of existing strategies developed to cope with future climate change for sorghum in north western NSW.
