Design with nature : a proposed model for coastal settlements in Australia adapting to climate change and extreme weather events

The Australian coast is rich in history and is scattered with coastal settlements amongst a contrasting landscape with infinite visual and ecological diversity. These attributes provide the opportunity to create sustainable and resilient settlements, linking the wholeness of a place to the foundation of living in harmony with nature. On the contrary the coastal regions of Australia are facing dynamic changes of population growth including the looming impact of a changing climate. Acknowledging these challenges, the Australian Government highlighted that one of the key requirements for a sustainable future is to establish sustainable settlements that are resilient against the impacts of climate change. Recent government studies and reports highlighted various possible impacts to the Australian coast and regional settlements due to sea level rise with associated coastal recession, extreme weather events, flooding, and prolonged heat waves. Various adaptation frameworks are proposed to deal with this issue, but very few consider the relationship between ecological systems and human built environments. The resilience planning of settlements must consider the co-evolution of human and nature under future climate effects. This paper is thus seeking answers to the question: How can the theoretical principles of Design with Nature (McHarg, 1967) and The Nature of Order (Alexander, 1980) provide for input to a adaptation model for settlements along the coast? Reflecting on a literature review of these two well established theories, the author select key principles from both as input to a ecological design based adaptation model for coastal settlements, which establishes a system of unfolding steps to create sustainable communities that connect with the landscape, and are resilient against future impacts of change.

The Victorian bushfires and extreme weather events : media coverage, crisis and communication

The 2009 'Black Saturday' Victorian bushfires claimed the lives of 173 people and have become known as the worst fire event in Australian history. Victoria has been at the centre of two other significant Australian fire disasters - 'Black Friday' in 1939 and the 1983 'Ash Wednesday' fires in south-eastern Australia that claimed the lives of 47 people in Victoria. As media scholar and commentator Michael Gawenda has noted, the media not only report an 'event' - like the Victorian bushfires or the tsunami in the South Pacific - but in a sense create and define it. Print and electronic media coverage of extreme weather events therefore raises a multitude of issues about the media's role in serving the community before, during and after a crisis, while also trying to produce the best possible reportage in a competitive industry undergoing dramatic change. This issue of MIA provides a venue for critical, empirical engagement with media coverage and representation, and the role of journalism and journalists in reporting national and international bushfires, tsunamis, hurricanes and other extreme weather events, with a special focus on the 2009 Victorian bushfires. Its goal is to address the ramifications of an industry in flux - indeed, some may say crisis - driven by technological advances, staff reductions and media organisations under financial pressure, and to explore the ways in which such extreme weather events have impacted media practices and policy

Using hospital standardised mortality ratios to assess quality of care--proceed with extreme caution

Australian Health Ministers have endorsed the hospital standardised mortality ratio (HSMR) as a key indicator of quality and safety, and efforts are currently underway towards its national implementation. In the United Kingdom, Canada, the Netherlands and the United States, the HSMR has been used for several years within organisations to monitor performance and response to various quality and safety programs. In the UK and Canada, the HSMR is also publicly reported and used to compare performance between hospitals. The validity and reliability of the HSMR as a screening tool for distinguishing low-quality from high-quality hospitals remain in doubt, and it has not yet been proven that HSMR reporting necessarily leads to worthwhile improvement in quality of care and patient outcomes.

Resistance and resilience: Can the abrupt end of extreme drought reverse avifaunal collapse?

Aim: Climate change is expected to increase the frequency and intensity of extreme climatic events, such as severe droughts and intense rainfall periods. We explored how the avifauna of a highly modified region responded to a 13-year drought (the 'Big Dry'), followed by a two-year period of substantially higher than average rainfall (the 'Big Wet'). Location: Temperate woodlands in north central Victoria, Australia. Methods: We used two spatially extensive, long-term survey programmes, each of which was repeated three times: early and late in the Big Dry, and in the Big Wet. We compared species-specific changes in reporting rates between periods in both programmes to explore the resistance (the ability to persist during drought) and resilience (extent of recovery post-drought) of species to climate extremes. Results: There was a substantial decline in the reporting rates of 42-62% (depending on programme) of species between surveys conducted early and late in the Big Dry. In the Big Wet, there was some recovery, with 21-29% of species increasing substantially. However, more than half of species did not recover and 14-27% of species continued to decline in reporting rate compared with early on in the Big Dry. Species' responses were not strongly related to ecological traits. Species resistance to the drought was inversely related to resilience in the Big Wet for 20-35% of the species, while 76-78% of species with low resistance showed an overall decline across the study period. Conclusions: As declines occurred largely irrespective of ecological traits, this suggests a widespread mechanism is responsible. Species that declined the most during the Big Dry did not necessarily show the greatest recoveries. In already much modified regions, climate extremes such as extended drought will induce on-going changes in the biota. © 2014 John Wiley & Sons Ltd.

Extreme nomadism in desert waterbirds: flights of the banded stilt

In contrast to well-studied Northern Hemisphere birds with spatially and temporally predictable seasonal migrations, waterbirds in desert biomes face major challenges in exploiting stochastic, rich, yet short-lived resource pulses in vast arid landscapes, leading to the evolution of nomadic behaviour. An extreme example is the banded stilt (Cladorhynchus leucocephalus), an opportunistic colonial breeder at remote inland salt lakes after infrequent rain events. Using satellite telemetry on 21 birds (tracked for a mean of 196.2 days), we reveal extensive, rapid and synchronized movement among individuals to and from salt lakes. Two birds left coastal refugia for the inland following rain, flying 1000-2000 km, while 12 others rapidly moved a mean of 684 km (range 357-1298 km) away from drying inland sites to the coast. Two individuals moved longitudinally across the continent, departing and arriving at the same points, yet travelling very different routes; one bird moving more than 2200 km in less than 2.5 days, the other more than 1500 km in 6 days. Our findings reveal movements nearly twice as long and rapid as recorded in other desert waterbirds. We reveal capability to rapidly detect and exploit ephemeral wetland resource pulses across the stochastic Australian desert.

The new wilderness: A practice-led model for arts based enquiry

The New Wilderness is a practice-led, multidisciplinary arts project first piloted by artists, writers, teachers and academics from Geelong, Deakin University and Courthouse ARTS Centre in 2013. In a series of workshops run by artists, and working to specific themes, the project provided a platform for participants to explore and respond creatively to change in the community; it culminated in a large-scale installation at Courthouse ARTS Centre’s main gallery. Our paper positions the project as a able to cut across convention, empowering young artists to respond to ‘big questions’ of relevance to the changing material, spatial and social relations within their communities. In questioning and seeking to transform communities into sustainable media, economic, environmental and social ecologies, this emergent model begins with a localised focus, which is designed to travel across time and place, and pedagogical frameworks. The paper positions Geelong as a community under radical transformation in its economic foundations and demographics. As artists and academics living and working in the region we see it as an experimental ground for investigations into a series of provocations that mirror the shape of the paper we intend to give. The provocations, as outlined in the workshops, might also be envisaged as new relations to:Object – From consumable to unusable to play. In revisiting the first iteration of The New wilderness in 2013 we discuss the ‘superfictional’ (Hill, 2000) enquiry that participants were asked to engage with. Its premise described Geelong as an abandoned, post-apocalyptic site. Participants were asked to imagine themselves as a group of future explorers and excavate objects from the city’s old tip. In unearthing their choices and re-presenting the objects in the gallery the participant was prompted to analyse site, situation, object and process as phenomena for ‘being’ or ‘telling stories’, providing insights into wider realms of cultural experience (Ellis, Adams and Bochner, 2010). Parallel to this ‘autoethnographic’ reflection our paper uses the philosopher Giorgio Agamben’s analysis of consumer and material culture. He traces the subject’s relation to objects from use-value, to exchange-value and in the era of extreme capitalism, to pure exhibition-value. He searches for ways that the objects produced in our material culture can be ‘profaned’ (Agamben, 2007). Space – From the material to the spatial to the situation. We are interested in how objects and the practices they elicit can be ‘profaned’ by their situation (Agamben, 2007; Wark, 2103). To profane, according to Agamben, is to open up the possibility that the object loses its exhibition-value to ‘a special form of negligence’ (Agamben). He uses the example of the child’s ability to insinuate any object into a new logic of play (Agamben). Like the objects excavated for The New Wilderness they could be from a variety of spheres – business, household, industry, health etc… The child, like the artist, reconstitutes, reorders and assembles new relations between things. In reflecting on the first New Wilderness project the paper correlates the creative response of the participant (student, child, artist) with the occupier. The Occupy Movement, which took up residence in many of the world’s cities’ financial districts in 2011, used a number of strategies commensurate with both Agamben’s notion of profanation and McKenzie Wark’s reading of the Situationist International’s use of détournement - as a strategy that releases objects and subjects back into the field of play (Wark, 2013). The field was taken by the occupy movement to be the space in which they occupied – capitalism, its logic and its practices, were, for a short time, redundant in the occupied field. The New Wilderness conceptualises the city as a localised field, from which its discarded objects can be ‘profaned’ or, repurposed, to reflect on shared histories, responsibilities, pedagogies and future action. Subject: self/other– As much as we propose New Wilderness to be a pedagogical initiative we see it as personal, critical and political. In the themed workshops, designed to elicit personal responses to the object and the site, which culminated in a multi-disciplinary installation, performance and/or text based work, participants were encouraged to think critically, and importantly, collectively. Through the four workshops run in the first iteration of the project participants were asked to re-consider their material value-systems, much as the occupy movement was trying to do, and like the occupiers, participants were empowered to be agents of change. Our paper reflects on the practical outcomes and the conceptual, political and pedagogical strategies embedded in The New Wilderness project. The paper affords us the additional opportunity to imagine a life for it in other geographical, socio-economic and educational situations.

Flight altitude of trans-Sahara migrants in autumn: a comparison of radar observations with predictions from meteorological conditions and water and energy balance models

Radar observations on the altitude of bird migration and altitudinal profiles of meteorological conditions over the Sahara desert are presented for the autumn migratory period. Migratory birds fly at an average altitude of 1016 m (a.s.l.) during the day and 571 m during the night. Weather data served to calculate flight range using two models: an energy model (EM) and an energy-and-water model (EWM). The EM assumes that fuel supply limits flight range whereas the EWM assumes that both fuel and water may limit flight range. Flight ranges estimated with the EM were generally longer than those with the EWM. This indicates that trans-Sahara migrants might have more problems balancing their water than their energy budget. However, if we assume fuel stores to consist of 70% instead of 100% fat (the remainder consisting of 9% protein and 21% water), predicted flight ranges of the EM and EWM largely overlap. Increased oxygen extraction, reduced flight costs, reduced exhaled air temperature, reduced cutaneous water loss and increased tolerance to water loss are potential physiological adaptations that would improve the water budget in migrants. Both the EM and EWM predict optimal flight altitudes in agreement with radar observations in autumn. Optimal flight altitudes are differently predicted by the EM and EWM for nocturnal spring migration. During spring, the EWM predicts moderately higher and the EM substantially higher flight altitudes than during autumn. EWM predictions are therefore in better agreement with radar observations on flight altitude of migrants over the Negev desert in spring than EM predictions.
