What's so special about the Murray-Darling Basin?
The Basin spans one seventh of our country, covering the Australian Capital Territory, large areas of New South Wales, Victoria and Queensland, and a small portion of South Australia.
It is home to our three largest rivers and over 30,000 wetland habitats, 15 listed under the Ramsar Convention as Wetlands of International Importance. It also plays host to a huge number of native plants and animals, many endangered.
Sixty seven per cent of the Basin's land is used for growing around 40 per cent of the nation's crops and livestock, hence the name "food-bowl of Australia". It also serves as the main source of drinking water for over three million Australians.
So what's the problem?
Lack of water is the broad, overarching concern. The Basin is parched due to almost a decade of harsh drought, the increasing effects of climate change, as well as poor water management.
When water is available in the river system, its flow is hampered by the Basin's 30 dams and 3,500 weirs.
Because of this, many regions of the Basin - the Coorong and Lower Lakes in particular - are drying out past the point of saving.
The problems are also threatening $9 billion of agricultural income. States that have control of the water have the opportunity to grow and make more money.
What are we going to do?
Short of praying and dancing for more rain, there are still solutions.
All farmers in the region own "water rights", which allow a stipulated quantity of water to be taken from the rivers for irrigation each year. The Federal Government is in the process of buying back many of these allocations from willing farmers. These buybacks are on behalf of the environment, meaning when it does rain, the rivers will be able to flow.
State governments are also pitching in, and the Murray Darling Basin Authority has been established to make sure the system doesn't reach this state again.
