Última Preferential Riverine Export of Fine Volcanogenic Particles to the Southeast Australian Margin ArchiMer Bayon, Germain; Douglas, Grant B.; Denton, Geoff J.; Monin, Laurence; De Deckker, Patrick. We report on rare earth element and neodymium isotopic compositions in a series of grain-size fractions separated from river suspended matter in the Murray-Darling Basin (MDB) and a nearby marine sediment core (MD03-2607) offshore south-eastern Australia. This source-to-sink approach was used to further investigate the extent to which sediment sorting may control the geochemistry of suspended loads in rivers, and to provide constraints on the source of the detrital sediment material exported to the ocean. Our results provide further compelling evidence that significant size-dependent geochemical decoupling can occur in river systems, accounting here for Nd isotopic (εNd) differences of up to eight epsilon-units between silt (>25 μm) and colloidal...

Ano: 2020 URL: https://archimer.ifremer.fr/doc/00610/72210/71005.pdf Taking Stock: Seventeen Years after the Murray-Darling Basin Agreement AgEcon Lee, Lisa Yu-Ting; Ancev, Tihomir. There has now been almost two decades of natural resource management by signatory states under the Murray-Darling Basin Agreement Despite significant public expense, the success of initiatives to improve the Basin’s environmental remains ambiguous. This confusion is partly due to poorly distinguished investment outcomes, a blurring of the transparency of public spending and a lack of accountability of decision makers. The aim of this study is to demonstrate that significant environmental improvements could have been achieved at a much lower cost if decisive action been taken early. The research report outlines the myriad of Murray-Darling Basin related policies and its funding. It also notes the achievements and impediments to program success.

Ano: 2008 URL: http://purl.umn.edu/94803 Water sharing for the environment and agriculture in the Broken catchment AgEcon Farquharson, Robert J.; Ramilan, Thiagarajah; Stewardson, Michael; Beverly, Craig; Vietz, Geoff; George, Brendan; Dassanyake, K.; Sammonds, M.. The Commonwealth of Australia Water Act 2007 changed the priority for water use in the Murray-Darling Basin (MDB) to first ensure environmentally sustainable levels of extraction and then to maximise net economic returns to the community from water use. The Murray- Darling Basin Authority (MDBA) is expected to deliver a draft Basin Plan in 2011 providing a framework for future water planning. The Plan will include Sustainable Diversion Limits (SDLs) which define water diversions for consumption while maintaining environmental assets and ecosystem functions. The 2009 MDBA Concept Statement acknowledged that in some areas less information is available to determine the SDLs. The 2010 MDBA Guide to the Basin Plan proposed SDLs reducing the current long-term...

Ano: 2011 URL: http://purl.umn.edu/100547 Turning Water into Carbon: Carbon sequestration vs. water flow in the Murray-Darling Basin AgEcon Schrobback, Peggy; Adamson, David; Quiggin, John C.. Large scale forest plantations in the Murray-Darling Basin may be embraced as a carbon sequestration mechanism under a Carbon Pollution Reduction Scheme. However, increased tree plantation will be associated with reduced inflows to river systems because of increased transpiration, interception and evaporation. Therefore, an unregulated change in land management is most likely to have a dramatic impact on the water availability. This will exacerbate the impacts of climate change projected in the Garnaut Review. This paper examines the implications of unrestricted changes in land use. These results should suggest the true costs to society from carbon sequestration by determining the tradeoffs between timber production and agricultural products.

Ano: 2009 URL: http://purl.umn.edu/47616 The complexities in environmental decision-making for the Murray-Darling Basin AgEcon Schrobback, Peggy; Mallawaarachchi, Thilak; Quiggin, John C.. People are part of a complex natural system and have the ability to actively interfere with their environment. Collective decisions made by governments represent social rules that limit the extent of people's interference with the environment that support them. Environmental decisions made by governments usually carry an ethical bias and are limited by the perception of the risks and uncertainties that may affect society's well-being in the medium to long run. The recently published Guide to the proposed Basin Plan represents a draft for a legislative instrument that aims to reclaim some of the water back onto the environment to safeguard declining natural ecosystems in the Murray-Darling Basin. By limiting diversions into agricultural uses, irrigators in...
