Water rushed down the bitumen driveways with more vibrancy than a typical urban canal. In the cooler and humid aftermath outside, a familiar smell was present. A wood fire? No – bushfire smoke! As we drove through the winding coastal streets, a haze hung over the vegetation, obscuring the collections of white houses with their slate grey roofs. It was an eerie reminder of recent years past. Having arrived at the beachfront, we climbed over the granite outcrop, trying not to slip on the wet rocks or disturb the mussels and cockles still bathing in their rockpools. Perching above the rising water, we could then see the smoke shrouding the bobbing boats in the protected bay. Although the winds soon changed and the bay returned to its beautiful, clear and slightly tormented self, I could not shake that feeling of Solastagia. This was northern Brittany, not the rocky Australian coastlines we learnt to recognise through the smoke of our own bushfires. Change is a destabilising concept for many, just as imagining the future can be. I have been particularly fortunate to work with many futurists, explorers, scientists, raconteurs, leaders, builders and people who thrive on complexity – people who seek to make sense of, and embrace, the systems and futures we have responsibility for creating. Those who do not just analyse the signals or raise alarms, but proactively work to support others to adjust their worldviews and actions, and creatively design and prepare for the uncertainties of what comes next.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43386460","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 floods destroyed 61 houses and swept some of them down into the sea. A monitoring and community-based early warning system (MCBEWS) was developed 2 years later. This paper presents the approach, development, and implementation of the system. There are two components, namely community capacity-building and the establishment of telemetric monitoring. The flood warning system considers two causes: extreme rainfall and landslide dam breaks. Raising awareness, workshops, training, and disaster organisation establishment appeared to effectively increase flood disaster preparedness capacity and community commitment. The adoption of a rainfall depth vs. intensity chart method for issuing flood warnings seems to be promising. The presence of an unusual flow reduction in the record during extreme rainfall indicates damming at the upstream of the record station due to landslides. Possible landslide dams near the downstream to the middle reaches might provide dangerous high peak discharge flash floods with short warning times.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44481167","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 health of Aboriginal and Torres Strait Islander Peoples living on traditional Country in remote Australia can be supported or undermined by these essential services. Despite global and Australian commitments to the Sustainable Development Goals, water and sanitation service levels have regularly been identified as unreliable, unsafe, and of a lower standard than non-Indigenous and non-remote settlements. This research sought to identify the optimal conditions to enable consistent delivery of safe water and sanitation in remote Indigenous communities of Australia. Using a combination of literature reviews, interviews with key stakeholder groups and applied research findings, key conditions for improved water and sanitation outcomes were identified. These included technology for water and sanitation that is fit for purpose, people and place; capacity-building, training and ongoing support for local Indigenous service operators; and that all personnel involved in delivery require a level of cultural competency to the local and Indigenous context. These findings are intended to contribute to informing more sustainable water and sanitation outcomes in Indigenous communities.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44844078","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 enabling legislation for the Basin Plan, the Water Act, gains its constitutional legitimacy from international treaties such as the Ramsar Convention on Wetlands. This Act mandated that water be returned from consumptive uses to the environment. An allocation of 2,750 GL/yr was set but has been reduced by the ‘Sustainable Diversion Limit Adjustment Mechanism’ (SDLAM), intended to achieve equivalent environmental benefits with less water. We present a synthesis of changes in decision contexts that have led to water reforms being ‘watered down’. We analysed the policy discourse of water reform to assess whether SDLAM projects will achieve outcomes congruent with Australia’s international treaty obligations. We found little or no alignment between the purpose of the SDLAM projects and the principles of the treaties and the Water Act. As water scarcity increases under climate change, attempting to conserve wetlands (including rivers) with less water while maintaining or increasing irrigation diversions is likely to prove maladaptive. A major reframing of environmental water policy and management is required to enable meaningful and effective adaptation to climate change.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44857532","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}

In this paper we report research to enable systemic-transformations praxis. We brought together water practitioners from various sectors for a number of systemic inquiry events across five Australian cities to understand what was required to begin a transition to WSCs. Using an approach influenced by systemic innovation, we designed an inquiry-based learning system. Our learning system design made scientific knowledge available for interpretation, internalisation and contestation, by practitioners in different contexts. The workshops led to identification of characteristics of WSCs; relevant issues and opportunities; and commitments and constraints to action constituting a baseline data set for future evaluation of progress. Transitioning to WSCs requires leadership, a supportive institutional-sectoral environment, practical implementation of technologies in social contexts and increased collaboration involving knowledge co-production across disciplines and sectors. Systemic inquiry methods lend themselves to revealing the socially constructed nature of urban water as hybrids of the technical, natural and social. Despite some limitations, our approach enhanced institutional innovation and investment and offers insights into future research and planning for enabling systemic-transformations praxis in multiple sectors and contexts.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46855471","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}

In this study, we investigate the long-term streamflow trends at 47 gauging sites within the southern Murray-Darling Basin (MDB), Australia. This study aims to estimate regional streamflow trends while understanding the impact of catchment characteristics on the spatial variation in these trends. To achieve this, we applied a Bayesian hierarchical model (BHM) to make the best use of available streamflow records from multiple sites and catchment characteristics such as climate, terrain, geology, land use and vegetation. The results show that streamflow trends from tested sites are consistently negative, with magnitudes of up to 2.7% per year relative to the annual average flow. We also find that spatial variability in trends can be best linked to differences in average climatic and terrain conditions. This finding can be used to inform future water planning for consumptive and environmental uses in the MDB.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43747908","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}

Energy optimisation can be approached from a number of perspectives, including design, equipment selection, instrumentation and control, energy recovery from the sewage, pumping off-peak, reuse of sewage and water treatment residuals, etc. Smaller water utilities with less than 50,000 people have less latitude for applying these approaches due the lack of economic viability for smaller facilities, lack of staff or other. Smaller water utilities must still strive towards reducing their carbon footprints but maintain affordability to rate payers. Public Works Advisory (PWA) provides technical, advisory and design services to Government Agency clients, including Local Government Areas or LGAs. The PWA partnership with LGAs assists at the local level to deliver on the commitments of NSW and Australia to reducing greenhouse gas (GHG) emissions by 2030. Directly reducing the take and use of grid power supplied by coal fired power stations can have favourable outcomes, both for reducing GHGs and OPEX. The use of solar photovoltaic (PV) systems in Australia is particularly attractive due to the continent having the highest direct normal irradiation or DNI. Current literature gives few examples of real operating data from PV systems in duty on water infrastructure, particularly for smaller installations. PWA target the highest OPEX areas for management of water and sewage and demonstrate with actual operating data from three full-scale case studies. PV panels can be economically employed by smaller water utilities for acceptable Internal Rate of Returns (IRRs), with or without batteries, to help reduce their overall carbon footprints.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49373725","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}

Syme","doi":"10.1080/13241583.2022.2088138","DOIUrl":"https://doi.org/10.1080/13241583.2022.2088138","url":null,"abstract":"Recently, there has been concern about social fragmentation, especially in western democracies, where trust in mainstream political processes and support of populist politicians has revealed that sections of the community feel isolated and disempowered. This phenomenon is also exemplified in the increasingly troublesome issues of environmental policy and management (Newig and Rose 2020). Responses to climate change have been inconsistent as systems approaches are required from societies when many institutions are currently organised only to deal with problems one at a time and in a sequential manner. The need for an integrated approach is best illustrated here by the requirements of water resources management. In the water cycle, there is an imperative to define each issue in terms of its relationship to another component. Everything is related to everything else. Upstream land use and management practices not only affect downstream water flows but also water quality (Fenemor et al. 2011a). There is little point in managing groundwater without understanding its relationship to surface water (Abbott et al. 2019; NZ Hydrological Society 2021). When catchment dams are poorly managed during drought, such as through spillway blocking or neglect, they can then fail under pressure from intense rain and exacerbate flood conditions (Tingey-Holyoak 2014; Pisaniello and Tingey-Holyoak 2017; Becker 2021). Problems occur when urban water is managed without reference to the catchments it comes from, or the receiving water environment (Vörösmarty et al. 2010). The way water is managed also has an obvious effect on uses and values as diverse as food production, industrial processing, recreation, and culture. This Special Issue addresses a range of policy issues pertaining to the economic, environmental, and sociocultural barriers and opportunities for more sustainable water management and planning. Papers on markets including investigating water trading in ways that go beyond popular approaches to consider the socioeconomic, ecological, and cultural needs, covering determinants of irrigators’ valuing of water in Australia (Haensch 2022), and whether water trading is a viable option for Aotearoa-New Zealand (Booker et al., 2022). Papers focused on equity and governance in water planning consider social justice implications of water planning (Brown et al. 2022; O’Donnell et al., 2022) and the need for improved stakeholder engagement (Broderick and McFarlane et al. 2022). Papers also consider the need for collaborative approaches, including how we design more holistic frameworks for New Zealand’s indigenous people (Robson-Williams, Painter, and Kirk 2022), how lessons from the past can inform the future and help design improved decisionmaking frameworks (Harcourt, Robson-Williams, and Tamepo 2022), and how intermediaries may assist in this process (Kirk et al. 2022).

Benchmarking against the National Water Initiative shows that NT lags behind national standards for water management. We describe key weaknesses in NT’s water law and policy, particularly for Indigenous rights and interests. NT is experiencing an acceleration of development, and is conceptualised as a ‘hydrological frontier’, where water governance has institutionalised regulatory spaces of inclusion and exclusion that entrench and (re)produce inequities and insecurities in water access. Regulations demarcate spaces in which laws and licencing practices provide certainty and security of rights for some water users, with opportunities to benefit from water development and services, while leaving much of NT (areas predominantly owned and occupied by Indigenous peoples) outside these legal protections. Water allocation and planning, as well as water service provision, continue to reinforce and reproduce racialised access to (and denial of) water rights. Combining an analysis of the law and policies that apply to water for economic development with those designed to regulate domestic water supply, we present a comprehensive and current picture of water insecurity for Indigenous peoples across the NT.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47429852","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}
