It represents one possibility for applying a dynamic allocation framework within which environmental river flows can be monitored and improved to support ecological, cultural, aesthetical and recreational values. Based on international experience, requirements for the successful implementation of water trading are assessed in the Aotearoa-New Zealand context. It is concluded that, if the environment is recognised as a water user, water trading has potential to promote sustainable water use but is associated with significant set-up and ongoing costs. A co-governance policy framework for water trading has not been agreed by iwi/hapū and the Crown based on Te Tiriti o Waitangi (1840). The institutional capacity required for development and implementation of trading is currently lacking, and the roles that government agencies and iwi/hapū would play are unclear. Market operational requirements relating to collection, collation and communication of hydrological data are only partially in place. Finally, New Zealand’s flashy hydrology is not conducive to seasonal water trading and smaller catchments may contain insufficient users to constitute a functioning market. Water trading should therefore not be viewed as an easily implementable solution for improved freshwater management.","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":"48364462","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}

Intermediaries connect, translate, and facilitate flows of information between different groups by positioning themselves between these groups. In this paper we focus on the roles of freshwater intermediaries who have been employed by local authorities and ask how these intermediaries help communities achieve freshwater quality improvements. To answer this question, we present three case studies of freshwater intermediaries working to improve freshwater quality in the Hawke’s Bay region of Aotearoa New Zealand (NZ). Our results suggest that intermediaries can help communities improve freshwater quality if they are given the time and resources to establish long-term relationships with communities, and if they are able to synchronise freshwater intermediary work with regional and national freshwater policy objectives. We conclude by arguing that freshwater intermediary work has been undervalued in NZ land and water management, resulting in local and central government attempting to resolve freshwater quality concerns through increasingly prescriptive and complex policy in regulations. Some specific lessons for use of freshwater intermediaries in New Zealand conclude the paper.","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":"44750365","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}

Some communities grew concerned about the impacts of intensive farming on water quality, river flows, and groundwater levels; others were concerned about a lack of meaningful reflection of Māori values in decision-making. In response, the Canterbury Water Management Strategy, published in 2009, promoted devolved collaborative governance of freshwater resources. A year later, regional councillors were dismissed by central government over concerns about water management and replaced by appointed commissioners through an Act of Parliament. The ensuing period of water management has been both praised and criticised. In this paper we examine water management in Canterbury through a case study in the Selwyn Waihora Zone. We use a causal framework to assess water management, focusing on the process that developed regulatory and non-regulatory recommendations and informed the Selwyn Waihora sub-regional section of the Canterbury Land and Water Regional Plan. We conclude that the collaborative process described is not a ‘quick-fix’ solution but a radical shift from previous approaches and, although it had some success, it might not be resilient to national political changes.","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":"46888781","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 was because of the state’s relatively low population for its size, a small irrigation industry (mainly based on self-supply groundwater) and the low level of secondary industry. Few resources were heavily over allocated despite the need to significantly de-rate water supply systems. The strong uni-directional drying signal in the south-west of WA has been an advantage in that new water supplies have been developed and/or demands reduced as conditions continued to dry, reinforcing the decisions made. Strong government leadership in adapting to a drying climate in the south-west, through accelerated and alternate water source developments has been extremely successful in mitigating dire impacts, especially in the Perth-Peel region. However, as drying and warming trends continue, there is less opportunity to develop new sources and a need to consider a wider array of sources, especially use in water resource planning. More nuanced planning requires stronger governance settings and increased engagement of stakeholders. A step change in the governance and sophistication of water planning and management could be achieved through new legislation in coming years.","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":"48643028","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}

Māori and non-Māori communities need decision-making frameworks that enable their values and priorities to inform land use choices. However, few of the available frameworks meet the needs of Māori communities. It is challenging to construct decision-making frameworks that have true utility for both Māori and non-Māori land stewards because of differences in their relationships with the whenua (land), the wai (the water) and te taiao (the environment). Additionally, Māori may utilise different types and formats of data in their decision-making from those traditionally encompassed by science-based frameworks. This paper aims to help non-indigenous researchers understand the required development processes and design features if a framework aimed at a broad audience is to have genuine relevance and utility for indigenous users. To achieve this, we utilised a modified version of Cash et al.’s Credibility, Salience and Legitimacy framework to evaluate a range of land use decision-making frameworks. We discuss why science-based concepts of holism are not the same as those embodied by a Māori worldview. We conclude that it is essential to co-develop frameworks in genuine partnership with Māori.","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":"42179727","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 concern is warranted, based on evidence of a century of ecological degradation. The national government responded with a series of freshwater policies starting in the 1940s, and environmental scientists have contributed to each successive policy. However, the science–policy interface in Aotearoa-New Zealand has often functioned poorly, due to science output with low policy relevance, long lag times (policy development lagging behind science advances, and vice versa) poor communications and other problems. The consequences have included continued degradation in the absence of appropriate regulation, and limited policy implementation due to inadequate scientific knowledge. In this paper, we address the challenges of freshwater science–policy interactions in in Aotearoa-New Zealand in three steps. First, we characterise effective and ineffective freshwater science–policy interactions over their 80-year history. Second, we recommend approaches for implementing the newest policy package, the National Policy Statement for Freshwater Management 2020. Third, we set out five imperatives to improve policy development in the future: inclusiveness, partnership with Māori, strategic planning, a funding mandate, and an authorising agency.","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":"47791101","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 Murray–Darling Basin Plan is intended to return water from irrigated agriculture to the environment but requires comprehensive, accurate water accounting to achieve this objective. Floodplain harvesting – the diversion and storage of overland flows into on-farm dams – is widely practised by irrigators in the northern Basin. By reducing volumes of river flows, floodplain harvesting has negative effects on downstream water users and the environment. The volume of diversions is not known, creating a major source of uncertainty over water availability and use. We focussed on floodplain harvesting in northern New South Wales (NSW) catchments (Border Rivers, Gwydir, Namoi, Macquarie and Barwon-Darling) because the NSW government is attempting to licence and regulate the practice. We found in 2019–20 there were 1,833 storages in these catchments with a total surface area of 42,650 ha. Storage capacity has risen from 557 GL in 1993–94 to 1,067 in 1999–2000, 1,225 in 2008–09 to 1,393 GL in 2019–20, a 2.5-fold increase in 26 years. We estimated mean annual floodplain harvesting take (2004–2020) in northern NSW was 778 GL (range 632–926 GL). For context, this volume represents half of the mean volume of held environmental water released annually for the entire Basin between 2009–10 and 2018–19 (1,576 GL) and six times that for the northern NSW Basin (125 GL). The volume of take from floodplain harvesting is not sustainable and in breach of legislation on water use and management. We discuss the negative impacts of floodplain harvesting on downstream communities and flow-dependent ecosystems and their social justice implications.","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":"49396192","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}

Lack of data from flooding events and the fragmentary nature of post-flood data are the factors hindering research in studying the impact of blockage on the performance of hydraulic structures. This paper proposes lab-scale simulations using scaled physical models of culverts to study the behaviour and effects of urban and vegetative debris. The first investigation studies the interaction between specific debris types with culvert inlet geometries and their impact on the hydraulic blockage. In the second investigation, a flood hydrograph is simulated in the laboratory to study complex relationships between blockage-related influential factors and to relate the observed visual blockage and hydraulic blockage. From the results of first investigation, urban debris was reported the main contributor in increasing the hydraulic blockage at structures. Furthermore, the degree of hydraulic blockage was found sensitive to the orientation of the debris. Results from the second investigation reported several insights regarding the complex relationships between blockage-related influential factors. The temporally variable nature of blockage was observed from the experiments that suggested revising the existing constant blockage based Australian Rainfall and Runoff (ARR) guidelines.","PeriodicalId":51870,"journal":{"name":"Australasian Journal of Water Resources","volume":null,"pages":null},"PeriodicalIF":3.2,"publicationDate":"2021-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44214211","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}
