Critical Reflections on Building a Community of Conversation about Water Governance in Australia

Water governance has emerged as a field of research endeavour in response to failures of current and historical management approaches to adequately address persistent decline in ecological health of many river catchments and pressures on associated communities. Attention to situational framing is a key aspect of emerging approaches to water governance research, including innovations that build capacity and confidence to experiment with approaches capable of transforming situations usefully framed as ‘wicked’. Despite international investment in water governance research, a national research agenda on water governance was lacking in Australia in the late 2000s as were mechanisms to build the capacity of interdisciplinary and transdisciplinary research and collaborative policy practice. Through a two-year Water Governance Research Initiative (WGRI), we designed and facilitated the development of a community of conversation between researchers concerned with the dynamics of human-ecological systems from the natural sciences, humanities, social sciences, policy, economics, law and philosophy. The WGRI was designed as a learning system, with the intention that it would provide opportunities for conversations, learning and reflection to emerge. In this paper we outline the starting conditions and design of the WGRI, critically reflect on new narratives that arose from this initiative, and evaluate its effectiveness as a boundary organisation that contributed to knowledge co-production in water governance. Our findings point to the importance of investment in institutions that can act as integrative and facilitative governance mechanisms, to build capacity to work with and between research, policy, local stakeholders and practitioners

Governing irrigation renewal in rural Australia

Irrigation renewal schemes are taking place globally for water conservation and gains in agricultural productivity, as competition for water resources increases. The publically-funded renewal of irrigation infrastructure is a key platform of water reform in Australia’s Murray-Darling Basin; it is considered by some to be a policy that contradicts market-based approaches. In this Australian study, we examine an irrigation renewal scheme in northern Victoria resulting from a large investment by the State and Federal Governments. The long historical development of infrastructure and institutions for irrigation in the region led to technological lock-in and exposure to international terms of trade and climate change. From interviews with water professionals involved in the region, three key themes were identified through an adapted grounded theory approach: (1) a lack of an appropriate platform for fostering community involvement in what was a large-scale investment of public money; (2) issues in the way that water losses and savings were calculated; and (3) contradictions in policies for water buyback and irrigation renewal that lead to some irrigators being disadvantaged. To better understand the situation, we also applied a theoretical lens based on social learning. We conclude that the framing of a water ‘crisis’ was used to the benefit of some irrigators in attracting large-scale investment of public funds for irrigation renewal. The proposed solution, a technologically-driven irrigation renewal scheme, was implemented at a pace that didn’t match the planning horizons for many, leading many to exit from irrigated agriculture. Systemic insights for the design and implementation of irrigation renewal schemes internationally are highlighted

Tapping Fresh Currents: Fostering Early-Career Researchers in Transdisciplinary Water Governance Research

Water governance is an important, yet complex and contested field. A central challenge for researchers is to engage with multiple understandings and perspectives that can shape water governance, and to move towards more transdisciplinary approaches. These challenges are magnified for early-career researchers (ECRs), and while the need for transdisciplinary approaches and better support for ECRs is increasingly recognised, there remains a lack of understanding of how to achieve this within the wider research community. Thus, this paper investigates through an auto-ethnographic inquiry the practical experiences and challenges faced by a diverse group of ECRs engaging in water governance research. Reflecting on our own endeavours and relevant literature, we identify a range of path-finding experiences and challenges, and explore strategies employed by ECRs to navigate the 'uncharted waters' of evolving career pathways in water governance research. 'Communities of Practice' are identified as a promising opportunity to support ECRs by enhancing opportunities for reflection and learning. Overall, we argue that there is significant merit in enhancing the way in which water governance research is understood, and improving the means by which ECRs are supported to build capability and contribute in this field

The paleobiogeographical significance of the Silurian and Devonian trilobites of Japan

Six major groups of trilobites from the Silurian and Devonian of Japan are evaluated for their paleobiogeographical signature. Silurian illaenids and scutelluids show four generic-level and at least two species-level links with the Australian segment of the Gondwana paleocontinent; encrinurids also indicate two generic-level links with Australia and also the South China paleocontinent; whilst Devonian phacopids, and possibly proetids, suggest at least two generic-level links with the North China paleocontinent. These different patterns may reflect the fragmentary biostratigraphical record of Japanese trilobites, but they also appear to reflect paleoenvironmental parameters associated with lithofacies, and paleoecology. Thus, Japanese assemblages of proetids and phacopids occurring in deep-water clastic lithofacies have counterparts in similar settings in North China, and Japanese scutelluids and illaenids are strongly associated with shallow marine carbonate lithofacies that are similar to those of their occurrences in Australia. Japanese encrinurids occur in carbonate rocks indicative of shallow marine settings in the Kurosegawa Terrane, and they demonstrate a consistent paleobiogeographical affinity with Australia and South China. Larval ecology cannot be directly assessed for Japanese trilobite groups. However, proetids have consistently been shown to have planktonic protaspides, whereas illaenids, scutelluids, and encrinurids have benthic protaspides. Planktonic protaspides would have a greater propensity for distribution in ocean currents than benthic ones, and therefore may be of more limited paleobiogeographical utility. The combined data from the six different groups indicates that the complex paleobiogeographical patterns of the Japanese trilobite assemblages need to be interpreted with caution, and similarity of taxa does not necessarily denote paleogeographical proximity to other regions

Quantifying exposure biases in early instrumental land surface air temperature observations

Exposure biases are a pervasive non-climatic change in land air temperature records which have been introduced as a result of changes in the way thermometers were sheltered from solar radiation and the elements over time. Exposure biases have not been widely accounted for in observational records, due to difficulties detecting/correcting the bias using traditional homogenisation techniques; therefore, exposure biases still contribute significant uncertainty to the early period in global temperature compilations. Here, an empirical approach to address the bias arising from the introduction of Stevenson-type screens from the late-19th century is presented. The approach consists of: (1) an empirical analysis of 54 parallel measurement series to identify the characteristics of the exposure bias in four exposure classes; (2) the development of bias-estimation models based on an analysis of which variables influence the bias; and (3) the application of the models to an extended version of CRUTEM5 (CRUTEM5_ext), based on exposure metadata, to quantify and reduce the bias. Step one identified differences between the temperatures recorded in Stevenson screens and early exposures, which vary seasonally, diurnally, and with location and exposure class. The largest biases (in mean temperatures) were found in freestanding exposures (up to −0.78°C annually) and in summer, while the smallest biases were generally found in wall-mounted exposures (near-0°C annually) and in winter. Significant relationships between the bias and temperature, downward top of atmosphere and/or received shortwave downward solar radiation were found in each exposure class and led to the development of three regression-based bias-estimation models. Application of these models to 1,960 mid-latitude stations in CRUTEM5_ext, resulted in small (≤0.016°C) positive adjustments to the Northern Hemisphere mid-latitude mean before 1880, and larger (≤−0.1°C) negative adjustments to the Northern and Southern Hemisphere mid-latitude means between 1882–1934 and 1856–1900, respectively. Larger adjustments were estimated regionally: up to −0.57°C annually and −0.79°C seasonally in individual grid cells

Genomic tailoring of autogenous poultry vaccines to reduce Campylobacter from farm to fork

Campylobacter is a leading cause of food-borne gastroenteritis worldwide, linked to the consumption of contaminated poultry meat. Targeting this pathogen at source, vaccines for poultry can provide short-term caecal reductions in Campylobacter numbers in the chicken intestine. However, this approach is unlikely to reduce Campylobacter in the food chain or human incidence. This is likely as vaccines typically target only a subset of the high genomic strain diversity circulating among chicken flocks, and rapid evolution diminishes vaccine efficacy over time. To address this, we used a genomic approach to develop a whole-cell autogenous vaccine targeting isolates harbouring genes linked to survival outside of the host. We hyper-immunised a whole major UK breeder farm to passively target offspring colonisation using maternally-derived antibody. Monitoring progeny, broiler flocks revealed a near-complete shift in the post-vaccination Campylobacter population with an ~50% reduction in isolates harbouring extra-intestinal survival genes and a significant reduction of Campylobacter cells surviving on the surface of meat. Based on these findings, we developed a logistic regression model that predicted that vaccine efficacy could be extended to target 65% of a population of clinically relevant strains. Immuno-manipulation of poultry microbiomes towards less harmful commensal isolates by competitive exclusion, has major potential for reducing pathogens in the food production chain

Synthesis and activity of a novel Autotaxin inhibitor-Icodextrin conjugate

© Copyright 2018 American Chemical Society. Autotaxin is an extracellular phospholipase D that catalyses the hydrolysis of lysophosphatidyl choline (LPC) to generate the bioactive lipid lysophosphatidic acid (LPA). Autotaxin has been implicated in many pathological processes relevant to cancer. Intraperitoneal administration of an autotaxin inhibitor may benefit patients with ovarian cancer, however low molecular mass compounds are known to be rapidly cleared from the peritoneal cavity. Icodextrin is a polymer that is already in clinical use because it is slowly eliminated from the peritoneal cavity. Herein we report conjugation of the autotaxin inhibitor HA-155 to icodextrin. The conjugate inhibits autotaxin activity (IC50 = 0.86 ± 0.13 μg mL-1) and reduces cell migration. Conjugation of the inhibitor increased its solubility, decreased its membrane permeability and improved its intraperitoneal retention in mice. These observations demonstrate the first application of icodextrin as a covalently-bonded drug delivery platform with potential use in the treatment of ovarian cancer
