Water-Energy-Food (WEF) Nexus in Agricultural Systems
Climate change has a significant impact on water and energy consumption, and food production. An integrated optimisation model will be developed to study the Water-Energy-Food (WEF) nexus, by incorporating nonlinear programming and Morris sensitivity analysis into a general framework. The method will then be used to optimize the profitability of the agricultural systems and identifying the trade-offs of water, energy, land use and GHG emissions under various resource and emission constraints. Selected case studies, involving cotton and wheat crops in the Darling Downs - Maranoa Region (Southern Queensland), will be used to illustrate the holistic set of procedures developed. Different waste management and climate change scenarios may also be considered.
