  1. Murray Darling Basin Plan

  2. Key Knowledge and Skills • Current management policies and strategies to implement these policies • The effectiveness of water management policies and strategies in terms of current use and future sustainability

  3. The Plan - origins • The water act 2007 established the MDBA as the body responsible for developing and overseeing the future management of the basins water resources • The largest scale change to water management since the Snowy Mountains Hydro-electric scheme. • October 2010 the MDBA released its Guide to the Proposed Basin Plan. • Concerns of the rivers health underpin the Basin Plan • An audit of the state of the rivers showed many were in poor state

  5. Sustainable diversion limits (SDLs) • Central point of the plan is to set environmentally sustainable limits on the amount of water extracted. • SDLs = the amount of water that can be used for consumption after the environmental requirements. • All forms of consumption, river diversions, floodplain harvesting, interception by farm dams and forestry • What was the river like in October 2010?

  6. Key points of the guide • Overall water allocations reduced between 27% and 37%, some as high as 45% • Reductions will come from buy backs and more efficient water delivery • Buy-backs would return an extra 3000 – 4000 GL to the environment = help keep the mouth of the Murray open 90% of the time • Loss of $800 million – $1.2 billion a year in agricultural production (dairy, cotton, rice)

  7. Short term impacts on some rural communities could be severe with a possible loss from 800 – 1200 jobs • Water regained would cost the Federal Government $2.3 million per GL • Total cost of the plan $6.9 - $9.2 billion • The guide allowed for a 10% reduction of water inflows over the next 20 years as a result of climate change

  8. Proposed cuts to water allocations Source page 78

  9. Reactions • Public outcry from many Basin communities • Many farmers felt they had not been consulted • Loss of jobs and incomes • Populations would decline as would the value of farms, houses and businesses • “this isn't a simple case of food verses the environment. This will create Centerlink towns throughout the basin” • Some environmental groups thought the guide was a positive move but it did not go far enough

  10. Looking ahead • The Basin plan was released at the end of 2012 • http://www.environment.gov.au/water/basin-plan/ • http://www.mdba.gov.au/

  11. The Future • Population • Climate Change • Challenges
