Rice and water in Australia: a debate set in a rapidly changing global context
The debate by three eminent scientists about whether growing rice in Australia is a waste of Australian water takes place in the broader global context of water scarcity and climate change. What are the details of the broader picture for Australia?
Firstly there is a severe drought affecting much of south east, particularly the Murray Darling Basin. Each week brings even more dire warnings from expert commentators about how severe the effects of the drought are for irrigated agriculture, the health of the river system and associated ecology. It is particularly alarming that, without rain, meeting urban water supply in the lower part of the Basin is uncertain beyond 2009-2010 - a very short time frame in which to plan mitigation.
The ramifications of drought significantly impact our ability to supply global and local grain markets. Many of us believe that the global economy changed irreversibly in the middle of the decade and we are witnessing a period of particularly rapid change. A number of major physical and economic forces are operating that will require significant adjustments to outlook and policy.
