The Murray-Darling Basin Plan is due to be released late tomorrow afternoon by the Murray-Darling Basin Authority. What will be released is the first instalment of its plan for the basin. The first instalment is a guide to the proposed plan. It will be followed by a draft plan, then the final plan. The bureaucratic wheels turn slowly.
Though the drought has broken in the Basin with the winter rains and water is now flowing though the system down through the lower lakes in South Australia, the political reality is that it is necessary to ensure that economic activity in the basin is aligned with ecologically sustainability. It is widely accepted that there had been an overallocation of water rights across every river catchment in the basin. So the plan must cut back the amount of water currently diverted for irrigation and to factor in the effects of climate change.
The background notes to the basin plan state:
At the heart of the Basin Plan will be limits on the quantities of surface water and groundwater that can be taken from the Basin water resources. These are known as ‘sustainable diversion limits’ (SDLs). The SDLs will take into account the best available science, and the ‘precautionary principle’....SDLs will limit the quantity of surface water and groundwater that may be taken from the Basin water resources as a whole. There will also be SDLs to limit the quantity of surface water and groundwater that can be taken from individual water resource plan areas and particular parts of water resource plan areas within the Basin. These areas will be defined in the Basin Plan and will draw upon current state water resource plan areas.
The mechanism to achieve this is the government spending billions of dollars ($5.4billion?) over the coming decade buying back permanent water rights from irrigators; and possibly redirecting government spending away from irrigation subsidies to the buyback of water rights "to achieve greater environmental benefits at lower cost.
This raises the question of where will the buybacks be targeted?
Rumors have it that the proposed cuts to irrigators' entitlements, are in a target range of between 27 and 37 per and the goal is to take 3000 and 4000 gigalitres litres from irrigators entitlements to add to water already quarantined for environmental flows.
That means that many irrigators would exit agriculture altogether because the plan will fail to deliver the water necessary to continue farming under the current over-allocated system. The targeted regions are the irrigation along the Murray and the Murrumbidgee. It is expected that the guide to the Murray-Darling Plan will recommend uneven cuts across the basin, with the Murray, the Murrumbidgee, the Goulburn Valley and Condamine-Balonne among the regions to face the greatest cuts.
The irrigators and the Nationals will oppose the cuts in the name of protecting the economics of regional communities and the social costs of the cutbacks. They assume that the drought is over, the rains will continue for several years, and that climate change will not impact on the Murray-Darling Basin. They will call for balance meaning that the policy goal of sustainable use in the Basin has shifted too far to the environment.
Update
The guide to the basin plan is here. Finally we have a step in water reform that is based on the Water Act 2007. This requires the Murray-Darling basin Authority to:
• give effect to relevant international agreements
• protect, restore and provide for the ecological values and ecosystems services of the Basin
• promote the use and management of Basin water resources in a way that optimises economic, social and environmental outcomes
• ensure the return to environmentally sustainable levels of extraction for water resources that are overallocated or overused
• maximise net economic returns to the Australian community from the use and management of Basin water resources while protecting, restoring and providing for the ecological values and ecosystems services of the Basin.
Though the Authority proposes to cut allocations by around 3000-4000 gigalitres the report said that this would not yield enough water to satisfy all environmental objectives, and consequently environmental ''tradeoffs'' would be required.

There is a need to redirect government spending away from irrigation subsidies to the buyback of water rights so as to achieve greater environmental benefits at lower cost.
