In Western Australia the East Wanneroo horticultural area is reliant on a superficial aquifer, the Gnangara Groundwater Mound, for irrigation. The area is affected by social and political change as the sprawling city of Perth expands, as well as by ecological changes resulting from a decline in groundwater levels. Horticulturalists face increasing competition for water allocation particularly with the drier conditions which are the consequence of two decades of reduced rainfall. This study provides a rationale for an educational intervention; explores the social, political, and ecological context of the East Wanneroo agricultural area; identifies gaps in current knowledge and understanding of the irrigation community and linkages between this community and their context which require further investigation and clarification; and outlines a theoretical framework which can be applied to develop a customized educational strategy aimed at improving irrigation practices and promoting sustainable communities and water usage.

This paper explores the notion of pluralism as it relates to the involvement of science in processes of environmental policy formulation. In particular, it focuses attention on the dominance of normal science within the Australian debate on commercial forest use, management, and conservation. It presents case study information from the Western Australian Regional Forest Agreement (RFA) process, a policy initiative designed to end a long-running conflict over public forestland. It then analyzes the use of science within this political process, along with the respective impacts of different voices within science on the RFA outcomes. The case study data highlight the vulnerability of reductionist science within complex political debates and support arguments for a widening of the scientific basis of policy processes to include alternative ways of understanding nature-society relations. The paper contends that such a broadening will make science not only more robust, but also more valuable as a problem-solving tool in future decision-making processes on land use, conservation, and broader sustainability questions. It also considers the obstacles facing pluralism.

This paper looks at the methods available to evaluate claims of significance of a toxic event or substance from the different perspectives of the toxicological analyst, the government regulator and the concerned public. Using arguments from a 'located toxicology', we propose the need for the adoption and use of methodologies that record the claims of concerned citizens, and evaluate the content of their claims for regulatory action and response.

Ecology is both blessed and burdened by romanticism, with a legacy that is multi-edged for health. The prefix 'eco-' can carry a cultural and political (subversive) baggage, associated with motivating environmental activism. Ecology is also practiced as a technical 'science', with quantitative and deterministic leanings and a biophysical emphasis. A challenge for planetary health is to avoid lapsing into, or rejecting, either position. A related opportunity is to adopt ecological thought that offers a rich entrance to understanding living systems: a relationality of connectedness, interdependence, and reciprocity to understand health in a complex and uncertain world. Planetary health offers a global scale framing; we regard its potential as equivalent to the degree to which it can embrace, at its core, ecological thought, and develop its own political narrative.

An update of taxonomic, distribution and conservation information for the freshwater crayfish Engaewa pseudoreducta Horwitz and Adams is presented. Engaewa pseudoreducta is formally listed as Critically Endangered by the state of Western Australia and under Australian national legislature, and informally in a recently completed international (IUCN Red List) global assessment of freshwater crayfi sh. Engaewa pseudoreducta was fi rst described on the basis of morphological characters of a small number of individuals from a single site, however the type locality was known to no longer support a population at the time of description and only one other nearby population was known prior to this study. This paper records two further populations and presents the fi rst genetic analysis of the species. DNA sequence data support the recognition of E. pseudoreducta as a species and despite the discovery of additional populations there appears no reason to lessen the conservation concern surrounding the species, particularly in light of continuing development in the area.

It seems obvious to say that research can provide benefits to multiple stakeholders and that stakeholder involvement is more often than not essential for research to proceed. Concrete examples of these mutual dependencies are valuable, where industry, government agencies and biological studies increase each others' potential and efficiencies. In the past 20 years the number of subterranean taxa discovered in Australia, especially in the Pilbara bioregion, has increased consistently thanks to environmental and biological surveys, often associated with mining development, but the investment on research needed to understand this vast biodiversity is far from what is required. The family Bathynellidae (Crustacea) occur in most Australian aquifers, but collecting them is not simple and their study and identification are very difficult due to their small and fragile bodies and their conservative morphology. Additionally, the poor and incomplete description of the type genus and species of this family (Bathynella natans Vejdovsky, 1882) have led to the assignment of many species occurring around the world, including Australia, to this genus. The taxonomic framework is therefore not well defined and their biodiversity and distribution assessments needed by government agencies become challenging. This research started with a collaboration with different environmental consultants who provided a conspicuous number of specimens collected through several years, which allowed an accurate analysis of specific aquifers. Studies of Bathynellidae populations occurring in different areas produced results useful to inform mining companies on species distribution and groundwater connectivity, underling the importance of cooperation among stakeholders. Morphological and molecular data reveal new genera and species with fascinating relationships, and the collection of some fresh material from type localities belonging to Bathynella clarifies the position of this "cosmopolitan" genus. This example demonstrates (again) the value of research as both underpinning, and supplementing, existing knowledge to improve the management and monitoring of the delicate subterranean environment and its resources.

Purpose– Academic approaches to the challenge of enhancing sustainability in research in university contexts illustrate that universities are affected by the very same values and socio-ecological issues they set out to address, making transformation difficult at every level. A theoretical and practical framework designed to facilitate cultural transformation is therefore necessary for conceptualising the problem and delineating possible strategies to enhance sustainability in research. Organisational change is also required, possibly on a university-by-university basis, where cross-institutional learning may be possible with personal behaviours that enhance collaboration across disciplinary and administrative divides.Design/methodology/approach– This paper contends that action research, in particular, community action research (CAR), offers the best approach to this task because it focusses on learning and change, and these are both essential to cultural transformation. A case study from a university in Western Australia is used to demonstrate this approach.Findings– The case study analysis shows some evidence for the presence of knowledge for organisational transformation, and that future monitoring cycles will be needed to detect the extent of the change.Originality/value– The paper introduces CAR as an approach to advance the change for sustainability in higher education and discusses some of the implications for universities who are looking to incorporate sustainability as a major part of their culture.

Large-scale food system practices have diminished soil and water quality and negatively impacted climate change. Yet, numerous opportunities exist to harness food system practices that will ensure better outcomes for human health and ecosystems. The objective of this study was to consider food Production, Processing, Access and Consumption domains, and for each determine the challenges and successes associated with progressing towards a sustainable food system. A workshop engaging 122 participants including producers, consultants, consumers, educators, funders, scientists, media, government and industry representatives, was conducted in Perth, Western Australia. A thematic analysis of statements (Successes (n = 170) or Challenges (n = 360)) captured, revealed issues of scale, knowledge and education, economics, consumerism, big food, environmental/sustainability, communication, policies and legislation, and technology and innovations. Policy recommendations included greater investment into research in sustainable agriculture (particularly the evidentiary basis for regenerative agriculture), land preservation, and supporting farmers to overcome high infrastructure costs and absorb labour costs. Policy, practice and research recommendations included focusing on an integrated food systems approach with multiple goals, food system actors working collaboratively to reduce challenges and undertaking more research to further the regenerative agriculture evidence.

Policies aiming to preserve vegetated coastal ecosystems (VCE; tidal marshes, mangroves and seagrasses) to mitigate greenhouse gas emissions require national assessments of blue carbon resources. Here, we present organic carbon (C) storage in VCE across Australian climate regions and estimate potential annual CO2 emission benefits of VCE conservation and restoration. Australia contributes 5-11% of the C stored in VCE globally (70-185 Tg C in aboveground biomass, and 1,055-1,540 Tg C in the upper 1 m of soils). Potential CO2 emissions from current VCE losses are estimated at 2.1-3.1 Tg CO2-e yr-1, increasing annual CO2 emissions from land use change in Australia by 12-21%. This assessment, the most comprehensive for any nation to-date, demonstrates the potential of conservation and restoration of VCE to underpin national policy development for reducing greenhouse gas emissions. ; This project was supported by the CSIRO Marine and Coastal Carbon Biogeochemical Cluster, CSIRO Oceans and Atmosphere, the ECU Faculty Research Grant Scheme and Early Career Research Grant Schemes, UTS Plant Functional Biology and Climate Change Cluster, NSW Southeast Local Land Services, Department of Environment, Land, Water and Planning (DELWP), Parks Victoria, Victorian Coastal Catchment Management Authorities (GHCMA, CCMA, PPWCMA, WGCMA, EGCMA), University of Queensland Centennial Scholarship, Hodgkin Trust Scholarship, Australian Institute of Nuclear Science and Engineering, Northern Territory Government Innovation Grant, Australian Research Council (DE130101084, DE140101733, DE150100581, DE160100443, DE170101524, DP150103286, DP150102092, DP160100248, DP160100248, DP180101285, LE140100083, LE170100219, LP150100519, LP160100242 and LP110200975), the Generalitat de Catalunya (MERS 2014 SGR-1356), the ICTA 'Unit of Excellence' (MinECo, MDM2015-0552), Obra Social "LaCaixa", SUMILEN, CTM 2013-47728-R, Ministry of Economy and Competitiveness and UKM-DIP-2017-005.
