{"title":"Risk of stream loss from changing irrigation, climate and groundwater extraction on the southern riverine plain of the Murray-Darling Basin in south-eastern Australia","authors":"G. Walker","doi":"10.1080/13241583.2023.2181292","DOIUrl":"https://doi.org/10.1080/13241583.2023.2181292","url":null,"abstract":"ABSTRACT The rivers of the south-eastern Murray-Darling Basin (MDB) and the associated irrigation areas of the southern riverine plain (SRP) in south-eastern Australia have undergone major hydrological changes over the last 30 years. These include a period of lower rainfall; a rebalance of surface water diversions between consumptive and environmental water uses under the MDB Basin Plan, improvements in water infrastructure; water trade out of the region; and falling groundwater levels. All these changes increase losses from streams to groundwater systems; potentially leading to the need for greater releases from dams to maintain baseflow in the major rivers. Baseflow is important for conveyance of water, water quality and baseflow-dependent ecosystems during dry periods. Hydrological changes in the SRP will reduce the streamflow by 2029–30 by an estimated 80 to 320 GL/yr. Further hydrological changes by 2029–30 will reduce the streamflow by another 50 GL/yr in the following decade. This is the first assessment of the cumulative stream impacts of the SRP and is relatively lower than previous assessments for single drivers. The current approach of mitigating unexpected losses is to increase conveyance loss budgets as required. This could be extended to mitigate the lower end of potential impacts; but further steps to reduce losses may be required towards the upper end. Further actions include a review of extraction limits for surface water and groundwater, trigger levels, and a greater shift towards conjunctive water management. Groundwater extraction, which has dominated impacts, is increasing from a relatively low proportion of the extraction limit in Goulburn-Murray Sedimentary Plain and shallow aquifers of the SRP. Over time, climate change will become more dominant as a driver. Most monitoring required to support mitigation already exists, but data is not collated or reported in a form relevant for stream impacts. Modelling also needs to be updated with reporting of more relevant outputs.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49525349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seemingly, ‘the plan’ and planning has to be all things to all people, but the reforms, instituted in the Water Act 2007 (Cwlth), have resulted in greater complexity, uncertainty and controversy. Effective governing of the Basin along an unfolding, viable trajectory within an Anthropocene-world seems more elusive than ever. In this context, we propose a research and praxis agenda for dramaturgy as an initiative that seeks ‘effective’ water governance in the MDB. A dramaturge is someone,group, body or process who writes/adapts a play, brings forth a particular type of performance set in an ever-changing audience/context. Dramaturges engage in praxis. Two exemplar dramaturgies , developed through ex poste and ex ante analyses, are outlined. Each can be refined or consolidated in an on-going deliberative inquiry-process that generates social learning and effects concerted action for future MDB governance. Our research inquiry is exploratory but is based on a choice to frame governance from a cyber-systemic perspective, a praxis continually enacted through the interactions of actors, their symbols and frames and feedback dynamics between the social and biophysical world. We show how a dramaturgical framework can be used to analyse a policy process to reveal the important symbolic and performative dimensions, which are usually unrecognised.

Given the Plans complexity, and issues involved in the revision it is worth asking what will be the main drivers of change? What changes can reasonably be anticipated? What preparations should stakeholders make for their engagement in the planning process? As we move towards the next Basin Plan, there are multiple wheels in motion that could shape the future. Several factors we anticipate being important are examined. Our aim is to stimulate stakeholders to think about and prepare for major contingencies that could affect their interests. We focus on those that will likely affect water availability, and changes in policy and water-governance by public agencies. We take the starting point that rivers are complex social-ecological systems, within which structural circumstances and forms of social capital will affect individuals’ and communities’ abilities to maximise what they achieve from their natural assets, and their resilience to unfavourable contingencies. We conclude with some observations about how stakeholders might strengthen their ability to respond to opportunities or threats. While the future is always uncertain and all planning processes are flawed, how stakeholders conceive of and respond to today’s challenges will substantially affect their capacity to be resilient.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2023-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42235598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This focus was reflected in the seminal paper on multiple risks to shared water across the basin by the Commonwealth Scientific and Industrial Research Organisation 15 years ago. That paper captured key concerns that were at the forefront for decision-makers, managers and policy-makers who were, at that time, experiencing the early impacts of the Millennium Drought. Water quality, then, was secondary to the issues of water security. Across the following years, new water quality risks have emerged along with a more nuanced understanding of the complex interplay between climate, floodplain/catchment vegetation, hydrology, and water quality. Critically, this improved understanding applies to the systemic shocks of extreme events, such as the 2020 bushfires and hypoxic blackwater events, as well as the variability, duration and volumes of natural and regulated river flows. In this paper, we explore the key water quality issues that currently face the Basin, and reframe water quality as an integral rather than incidental component of the risks to shared water in the Basin, with the associated implications for policy development that this implies.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45090276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CSIRO outlined six major risks to shared water resources in the Basin. Herein, six groups of researchers have reviewed the risks of climate change, forest growth, groundwater, water infrastructure, water quality, and governance. These reviews bring an updated understanding of risk assessment and management that can contribute to the forthcoming reviews of the Water Act and Basin Plan in 2024–26. Drawing on these six papers, the authors synthesise knowledge of the risks to shared water resources and identify policy and management options and information gaps. We find that few risk factors have decreased in significance. Most risks remain and new risks are identified. Water managers must plan for a significant decrease in water availability and governments need to actively manage these risks under conditions of increasing uncertainty.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46450105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MDB is home to 2.6 million people and produces about $24 billion worth in agricultural production each year (about one-third of total value for Australia). Hydrologic issues, typified by water availability and quality, have existed for many years, peaking during the Millennium drought from 1997 to 2010. Competing interests (i.e. irrigation, tourism, environmental heath), and the declining flows and water quality during droughts, led governments and water management agencies to consider the risks to water resources in the system in the early-mid 2000s. This paper reviews changes to risks associated with forest dynamics, as identified by - afforestation and bushfire – and considers new issues that have emerged since that analysis. It was found that the potential impacts of bushfire on stream flows were over-estimated in past studies, and that a planned significant afforestation expansion into agricultural and grazing land that was projected to reduce stream flows did not occur. While these two risks now do not seem likely to have significant future impacts on flows, or consequent effects on downstream users, the interaction of elevated CO2 and increasing temperatures on vegetation functioning and subsequent hydrologic consequences at catchment scale require further research and analysis. Reduced rainfall and increased temperatures under future climate change are likely to have an impact on inputs and flows. Uncertainties in how these changes, and feedbacks between climate, drought, more frequent fire and vegetation responses, impact on system hydrology also require further investigation.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47220736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our analysis of the problems and opportunities for reform is informed by the OECD’s principles of good water governance and the legal concept of the rule of law. We conclude that ignoring opportunities to adopt better-practice water governance is a severe risk to the MDB’s shared waters. To overcome reactionary crisis-reaction reform, we propose reforms that empower critical evaluations of governance structures, rules, practices and participation. Therefore, proposed reforms of policy, institutions and legislation do not simply attempt one-off changes to enhance transparency and accountability but instead seek to enshrine processes of continuous, ongoing improvements to water governance.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44193497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
