Climate change scenarios and managing the scarce water resources of the Macquarie River /

For managers of scarce water resources, climate change presents both risks and opportunities that previously have been largely ignored. This report considers climate change scenarios for the year 2030 and potential consequences for water resource managers in the Macquarie River region of New South W...
