Abstract:

Three environmental change scenarios (the best scenario, the most likely scenario and the worst scenario) were used by the APSIM (Agricultural Production System sIMulator) Wheat module to study the possible impacts of future environmental change (climate change plus pCO2 change) on wheat production in the Mid-Lower North of South Australia. GIS software was used to manage spatial-climate data and spatial-soil data and to present the results. Study results show that grain yield (kg ha-1) was adversely affected under the worst environmental change scenario (-100% ∼ -42%) and the most likely environmental change scenario (-58% ∼ -3%). Grain nitrogen content (% N) either increased or decreased depending on the environmental change scenarios used and climate divisions (-25% ∼ +42%). Spatial variability was found for projected impact outcomes within climate divisions indicating the necessity of including the spatial distribution of soil properties in impact assessment. © Springer 2005.
