However, it is highly likely that conversion to these systems will increase on-farm energy consumption and greenhouse gas (GHG) emissions, suggesting potential conflicts in terms of mitigation and adaptation policies. This study explored the trade-offs associated with the adoption of more water efficient but energy-intensive irrigation technologies by developing an integrated assessment framework. Integrated analysis of five case studies revealed trade-offs between water security and environmental security when conversion to pressurized irrigation systems was evaluated in terms of fuel and energy-related emissions, except in cases where older hand-shift sprinkler irrigation systems were replaced. These results suggest that priority should be given, in implementing on-farm infrastructure investment policy, to replacing inefficient and energy-intensive sprinkler irrigation systems such as hand-shift and roll-line. The results indicated that associated changes in the use of agricultural machinery and agrochemicals may also be important. &rft.creator=Mushtaq, Shahbaz, Doctor &rft.creator=Maraseni, Tek Narayan, Doctor &rft.date=2011&rft.relation=http://eprints.usq.edu.au/19695/&rft.coverage=151.1,-26.8 152.1,-26.8 152.1,-26.2 151.1,-26.2 151.1,-26.8&rft_subject=Environment and Resource Economics&rft_subject=Economics&rft_subject=Applied Economics&rft_subject=Natural Resource Management&rft_subject=Environmental Sciences&rft_subject=Environmental Science and Management&rft_subject=Agricultural Systems Analysis and Modelling&rft_subject=Agricultural and Veterinary Sciences&rft_subject=Agriculture, Land and Farm Management&rft_place=Australia&rft.type=dataset&rft.language=English Go to Data Provider
