A public lecture at Charles Sturt University (CSU) in Orange will shed light on the nature of the trade-offs involved in the proposed transfer of water to the environment in the Murray Darling Basin. Professor Kevin Parton a lecturer and researcher at the CSU School of Marketing and Management, is an expert commentator on the economic and social effects of the water transfer. His presentation is at 6pm Friday 20 April, and he believes there will need to be trade-offs between economic, social and environmental objectives when increasing the flows of water in the Murray-Darling system, which is Australia’s largest river system. “The Murray-Darling Basin Authority has proposed to transfer 2 750 gigalitres per year from irrigation to environmental flows,” he said. “Many farmers consider the costs of even the smallest transfer to be prohibitive, while many conservationists regard anything less than 4 000 gigalitres per year as insufficient to capture any significant environmental benefits.” Professor Parton will consider a number of findings from preliminary research in this controversial topic, including the costs to irrigation farmers, the amounts of environmental water needed, gains for Murray-Darling communities from the plan, and the effects on losers from the plan.
