Impacts and adaptation to climate change in beef production systems in central Queensland

摘要

@@Introduction Trends in Queensland's grazing lands related to climate change,and increases in atmospheric carbon dioxide (CO2 ) raise questions about the future productivity of various industries,particularly those on the climatic margins ( Howden et al.,1999).Here we investigate the impacts of climate change at Emerald (23°31′S,148°10′E,mean annual rainfall 648 mm) using a pasture growth model (GRASP) to examine the sensitivity of pasture growth to a range of climate change scenarios and two stocking strategies (constant and responsive).
