The Paper Water Problem
The Murray-Darling Basin Plan attempted to create an efficient market for water. Instead, it created allocations for water that does not physically exist.
By uncoupling water rights from land ownership, Australia created one of the most sophisticated water trading markets globally. However, the foundational models were based on historical rainfall averages that climate change has rendered obsolete.
Over-allocation vs Reality
The core structural issue is 'over-allocation'. The total volume of water licenses issued across the basin frequently exceeds the actual volume of water flowing through the river system during dry years.
The Deficit Allocation Model
See how 'paper water' (licenses) conflicts with physical reality during a dry cycle, forcing painful allocation cuts.
Frequently Asked Questions
- Why not just buy back more water?
- Commonwealth buybacks reduce the pool of available licenses, which spikes the price of water on the spot market. This accelerates the transition away from dairy and rice toward high-yield permanent plantings like almonds, fundamentally altering regional economies.
