Presentation Transcript

  1. To assess the impact of climate change/variability and develop adaptive responses for the mixed grain/livestock production systems SIMULATION MODELS CROP/PASTURE DSSAT APSIM CLIMATE CHANGE SCENARIOS GCM Sensitivity analysys Scenario based on past changes

  2. INPUTS CLIMATE SOIL CULTIVAR MANAGEMENT PROCESSES GROWTH & DEVELOPMENT WATER/N BALANCE OUTPUTS GRAIN YIELD & COMP BIOMASS PHENOLOGY WATER/NITROGEN CROP/PASTURE MODELS

  3. Changes in median values between 1930-1960 and 1970-2000 used in future scenarios.

  4. Simulated Yield (DSSAT) Scenario based on past changes

  5. Future tasks: • To assess regional impacts • To evaluate other scenarios • To improve temperature and radiation in WG • To consider mixed systems

  7. This module is not fully integrated within the APSIM environment. Not suitable for rotations Development of a new Module to simulate pasture growth Pastures in APSIM APSIM- GRASP Rangeland production This module does not simulate root growth, the nitrogen cycle and the effect of increasedCO2 concentration.
