Fellow, CSIRO Land and Water, - 5th Annual Australian Water Summit, Monday 26th
February 2007
2A caveat
- Predicting the future is risky.
- We do it to discover what might go wrong.
- And how we can improve the future we actually
experience. - What follows is fictional,
- It is offered in good faith.
- We try to bring together what many have been
recommending.
32 Case study histories
- Southern Connected River Murray System
- Large surface water system with very large
storage indirectly connected to a series of slow
moving groundwater systems of varying quality - South East of South Australia
- Unconfined groundwater water system
4Climate shifts occur
8yrs.
11yrs.
A drought, Australia should have expected (not a
1 in 1,000 years event)
5River Murray Inflows 2007/8
- By May 2007, all Murray System dams empty
- 2007/8 inflows gt 1,000 GL
- South Australia got its 1/3 gt
333 GL - But SA system evap. losses gt 1,300
GL - Balance
967 GL - Add back Wellington weir Lake Bonney triage
L. Alexandrina and L. Albert 1,100 GL - Available allocation to SA cities, vines, etc
133 GL - Lakes became Southern Hemispheres Aral Sea!
6New Governance
- Well briefed, in Jan 2007 Howard requested
referral of MDB management powers to
Commonwealth. With 3b 1.6b 3.6b 8.2b to
fix over-allocation. - In Feb 2007, all states but Victoria agreed to an
Independent Murray Darling Basin Authority
responsible for - Running the entire system as one
- Allocation announcements trading rules
- Entitlement registers
- Stopping over-allocation from re-occurring
- Moving from one political system to another was
not enough! An independent Authority was needed! - Victoria agreed to sign on only after they had
seen Commonwealth legislation passed in February
2008
7MDB Act and new Agreement
- The 2008Act established an Authority using the
Uhrig Commission template - New MDB Agreement to be established as schedule
- SA insisted on a detailed MDB Agreement
- 200 GL minimum flow through Mouth to recover the
Lakes and save the Coorong - SAs high security entitlements combined with NSW
and Victorias and Adelaides urban water
tradeable - Carry-over for all water in all States
- Binding power referral only when over-allocation
solved - (When the Agreement came into force, the
responsible Minister was no longer Malcolm
Turnbull!)
8Recovering from over-allocation
- 2008 Commonwealth started buying entitlements
- Used simple one page buy-back offer
- (The 2007 30 page efficiency contract failed)
- By the end of 2009 (one year later) 2,000 GL had
been secured for the environment and leased back
for two years at cost of 3 billion - Some compulsory acquisition of isolated farms
occurred.
9SAs South East Ground water system
- Since 2000, the SE had been progressively and
quietly converting from groundwater area
licences, to meters, to volumetric allocations
and then shares over 8 years - Full volumetric allocation system from 2009 with
capacity to carry forward up to 90 of any
allocation - Gave all an initial 25 carry over at the start
- No-one complained. The SE NRM Board had been
open, inclusive and transparent. - Coonawarra wine just kept on coming from the
system! - Dairy moved autonomously from the SA lakes to the
SE.
10MDB Authority functions and powers
- s. 9 The Authority, in the performance of its
functions, must pursue the objectives of - Ensure over-allocation does not recur
- Efficient and cost effective management
- Maximise economic efficiency in use of MDB water
- Ensure accountability
- Achieve cost-recovery targets
- s.10 The Authority must do all things that are
necessary or convenient to be done for, or in
connection with, the performance of its functions.
11Neutralising flow-reduction activities
- As the Aust. NWI gave states until 2010 to plan
to fix water interception, nothing was done about
interception as it was called until 2011 - Economists, scientists, the Senate, the
Productivity Commission had repeatedly warned
that about an interception train wreck! - The 93/94 Cap was set so that only 28 of mean
flow went to the environment. - Since then flow interception by forests, by farm
dams, by increases in salinity interception, and
by increases in water use efficiency had reduced
the mean flow allocation to 10! The River was
still going out backwards. - It was finally realised that this was why the
lakes were dead and a dredge was used to keep
open Murray Mouth!
12Plantation Forestry offsets
- South East introduced offset rules for rainfall
interception in 2006 and tapping by roots into
aquifers in 2008 - Forestry in top of MDB catchment costs 3,000 per
hectare in water entitlement erosion - In 2011, MDB Authority announced it was better to
be around 80 right than 100 wrong and ordered
use of Zhang curves still the best available
science. - The Authority announced that each states must
surrender sufficient entitlement to offset the
estimated effect or the Authority would do it for
them. The Minister chose not to intervene even
though all up-stream States called for it.
13Water-use efficiency and flow erosion
- South East in 2006 converted area licences into
entitlements that recognised that under flood
irrigation 50 of groundwater returned to
aquifer. - Decided if an irrigator moved to a more efficient
spray or drip system they would be allowed to
pump less gt much less! - MDB Authority decided to try to deal with the
issue in the River Murray system. - Technical increases in water use efficiency
decreased river flow!
14Infrastructure investment and technical efficiency
- Howard Plan economics
- 3.1b for delivery efficiency gains
- 1.6b for on farm efficiency gains
- savings to be split 5050
- If the Plan went ahead 1,250 GL would have to be
purchased. gt an additional 53 cost burden. - By 2009, it was realised that it was more carbon
efficient to stay with gravity fed systems and
more economically efficient to solve
over-allocation by buying water and fixing this
accounting problem. - Leave structural adjustment to farmers and
infrastructure management to water supply
companies. - In 2010, the NWI pricing rules were reinstated.
- By 2015, all water supply companies became carbon
neutral
15Offsetting the effects of farm dams
- As with trees, farm dams stop water flowing into
rivers. - In 2016, decided to make Local Government in NSW
and Victoria pay for the cost of offsetting this
impact. (SA had NRM board levies.) - Resulted in dramatic local government boundary
reform and transfer of NRM to local governments
now aligned with catchment boundaries. - The Authoritys power to do all necessary to stop
over-allocation from re-occurring was starting to
bite.
16Ground-surface water connectivity
- Under the NWI, 2014 was the D-day for Govt to
start paying compensation for scientific error. - But there was no allocation in the NWI or the
Plan for research. - New science in 2015 revealed connectivity was
underestimated by 30. - More entitlements would have to be purchased!
17Funding change
- How could all this be financed?
- By 2015, the Commonwealth already charged
- A fixed fee per entitlement for system overheads
- A fee in proportion to any allocation made
- States charged
- A fee in proportion to the volume of water used
- Parliament considered a River Return.
- Every year, 2 of each entitlement holding would
be put up for tender and the money used to
support community development and stop
over-allocation. - The proposal failed to get Senate support and
failed. Taxpayers kept on supplying the money.
18Counter-cyclical trading of Env. water
- Environmental water managers can sell one years
allocation in a drought and use the money to buy
entitlements. - By 2013, the MDBA held over 3,000 GL for the
Environment and it was a drought again. - Agreement was amended to allow counter-cyclical
trading. - Early in 2014, a superannuation trust took the
MDBA to court for insider trading. - The claim was that the Authority announcements
took into account counter-cyclical trading
opportunities. - In 2015, an Independent River Murray Environment
Trust was established.
19Water Supply Sharing
- In 2014, the new Env. Trust moved immediately to
broaden the portfolio of water products it held. - Options contracts were ruled out.
- Revived Murrumbidgee Irrigations River Reach
Proposal - Trust purchased a wet-period share in a 50 GL
Murrumbidgee River entitlement. - Split allocations 5050 split based on a 10 yr
moving average - 100 to irrigators when under the moving average
- 100 to Trust when over the moving average
- Entitlement time share contracts were born.
- By 2027, this accounted for 25 of the Trust
portfolio.
20A climate-adjusted cap
- In 2007, the South East decided to allocate water
volume on basis of moving average of last 5 years
recharge estimates. - Allocations would adjust autonomously with long
term supply shifts to stop over-allocation. - Carry over of allocations allowed.
- In 2010, when the MDB Authority commenced, it
immediately defined the cap as a 10 year moving
average. - The Authority defined all unconfined groundwater
within 5kms of the River as surface water.
21Water entitlements, registers and trading
- While each MDB State has its own register, the
Howard Plan promised a single MDB register! - In 2007, new Minister for Water asked SA to
unbundle
Water licence (Consent)
All registers transferred to Victoria. Register
integrity guaranteed. Electronic trading of MDB
allocations in 2009.
22Allocation announcements derivatives
- In late 2006, many MDB allocations were cut.
- SA announced an 80 allocation and people started
trading, a month later it was cut to 70 and then
another month later to 60. - Some NSW irrigators had water allocations they
had carried forward cancelled. - In 2008, the MDB Commission announced it would
make monthly announcements that were definitely
available. Allocations, once made, were
guaranteed. - In 2009, a futures market emerged
- Sydney Futures Market offered contracts on 600 ML
of water to be delivered at Griffith on 30th
December. -
23Barriers to water trading
- In 2009, the World Bank reviewed Australian water
reform and focused on exit fees. - In 2010, the Authority enforced the ACCCs 2006
recommendation that exit fees should not be
greater than 8 times the annual access charge. - Late in 2010, banks began were offering a 1
discount on loans whose mortgaged was registered
on the Victorian entitlement register. - Water supply company shareholders revolted and at
AGMs across the country voted to devolve
entitlement ownership to each individual and
transfer them to the Victorian register.
24The business of water trading
- Burnt by insider trading allegations in 2014, in
2015, the Authority ruled that no water supply
company could have any interest in any water
trading business. - Victoria was forced to sell off Goulburn Murray
Waters Watermove internet trading business and
Queensland to sell off Sunwaters trading
business. - Purchased by Waterfind and the Water Exchange.
- In 2018, water trading moved to the Bendigo Stock
Exchanges electronic trading network.
25Insights from the future
- Governance and robust accounting have been
Australias two biggest water management mistakes - Attention to detail is critical. Design systems
for - Trading
- Change (climate, technical, economic social)
- Wealth creation and environmental protection
26The future depends upon how we talk about it
