We investigate the development of stationary energy policy for the national and sub-national ecological footprint. Three carbon emission mitigation scenarios relating to the electricity sector (two different fuel mix scenarios and the rate of technological uptake) are explored. We find that the effectiveness of sub-national policy varies with global uncertainty. To be robust, policy to reduce carbon emissions from the stationary energy sector must be successful irrespective of which future eventuates and/or must be highly adaptable and responsive to different futures. We investigate the impact of emission reduction policy on other parts of the ecological footprint—energy land. Many low carbon energy production methods require large areas of land, and this exacerbates current land use competition, particularly with respect to agricultural land. We find that holistic policy development will need to identify land uses which can operate synergistically with land required for renewable energy to mitigate ecological footprint expansion as renewable energy increases. Our case study using Australia and four of its states provides a framework applicable elsewhere in the world to increase the resilience of the energy sector and agriculture.

Due to the unknown spatio-temporal distribution of Battery Electric Vehicles (BEVs) charging load, introducing large quantities of BEVs in the transportation sector has drawn growing concerns about its negative impacts on the power grid system. Based on real-world vehicle driving survey data, this paper presents a deterministic and a probabilistic model to quantitatively investigate the spatio-temporal distribution of BEV charging load for Australia. Whilst the trip-chain-related travel parameters for the deterministic model are directly taken from travel survey data, those for the probabilistic model are generated by the k-Nearest-Neighbour (kNN) algorithm. The probabilistic model is validated and applied to simulate the spatio-temporal distribution of BEV load based on GISgridded data for Australia. We are able to distinguish different temporal BEV charging load distributions for weekdays and weekends, and a heavy spatial concentration in capital cities.

The vulnerability of the urban residential sector is likely to increase without the mitigation of growing household Ecological Footprints (energy demand, CO2 emissions, and demand for land). Analysis comparing the effectiveness and robustness of policy to mitigate the size of the housing Ecological Footprint has been limited. Here, we investigate three mitigation options: (1) reducing housing floor area, (2) improving the building envelope efficiency, and (3) reducing the carbon intensity of the electricity sector. We model the urban residential Ecological Footprint for a sub-national case study in Australia but analyse the results in the global context. We find that all three mitigation options reduce the Ecological Footprint. The success of policy to reduce household energy demand and land requirements is somewhat dependent on uncertain trajectories of future global population, affluence, and technological progress (together, global uncertainty). Carbon emissions reductions, however, are robust to such global uncertainty. By reducing the Ecological Footprint of the urban residential housing sector we see a reduction in its vulnerability to future global uncertainty, global carbon price, urban sprawl, and future energy shortages. Over the long term, such policy implementation can also be highly cost effective.

We offer a simulation of low-carbon electricity supply for Australia, based on currently and economically operating technologies and proven resources, contributing new knowledge by: featuring a GIS-based spatial optimisation process for identifying suitable generator locations; including expanded transmission networks; covering the entire continent; and investigating the significance of biofuel availability and carbon price. We find that nation-wide low-carbon electricity supply is possible at about 160 GW installed capacity, at indicative cost of around 20 ¢/kWh, involving wind, concentrating solar, and PV utilities, and less than 20 TWh of biofuelled generation. Dispatchable hydro and biofuel plants are required to plug gaps caused by occasional low-resource periods. Technology and cost breakthroughs for storage, geothermal, and ocean technologies, as well as offshore wind deployment would substantially alter our assessment

Communicating complex environmental challenges to diverse audiences is a key skill required of graduates from higher education in the field of sustainability. This chapter describes the use of Pecha Kucha (a highly constrained presentation format requiring exactly 20 simple, image-based slides each presented for 20 s) as a way to facilitate class discussions. Pecha Kucha presentations by all students in the class can be combined strategically to cover different aspects of an entire course to support students’ cumulative, holistic learning, in a manner similar to jigsaw and other cooperative learning strategies. Presenter-generated questions serve as prompts for subsequent discussions to encourage critical thinking and collaborative learning by both the student facilitator and her peers. The learning activity builds students’ (i) understanding of, and (ii) communication skills about, environmental and sustainability issues. After presenting and engaging in peer-to-peer discussions, students should be able to (1) research an environmental issue and use critical thinking to distil its salient, core elements and (2) communicate effectively about environmental issues through Pecha Kucha presentations and asking related open-ended questions and (3) develop a broader understanding of environmental issues through watching and discussing peers’ presentations.

This study examined and compared attitudes of both students and instructors, motivated by an interest in improving the development and delivery of online oral communication learning (OOCL). Few studies have compared student and instructor attitudes toward learning technologies, and no known studies have conducted item response theory (IRT) analyses on these factors. Two independent and anonymous surveys resulted in 255 participants (124 university students, and 131 instructors). Exploratory factor analyses produced final item sets and a two-factor model for student attitudes (Technology Self-efficacy [TSE], and Positive Attitudes [PA]), and a three-factor model for instructors (TSE, Behavioral Intentions, and PA). The OOCL attitude factors showed strong validity through both IRT and classical test theory analyses. Comparisons between students and instructors showed students generally had higher TSE and more positive attitudes towards OOCL. The attitudes most relevant to OOCL were intrinsic interest, behavioral intentions, and perceived usefulness of the technology. This study revealed that technological self-efficacy may be useful for differentiating students and instructors, but not for assessing OOCL attitudes. Further development in this field could focus on the improvement of instructors’ attitudes and skills, as well as exploring the role of intrinsic interest.

Purpose – The purpose of this paper is to evaluate the experiences of tertiary students learning oral presentation skills in a range of online and blended learning contexts across diverse disciplines. Design/methodology/approach – The research was designed as a “federation” of trials of diverse online oral communications assessment tasks (OOCATs). Tasks were set in ten courses offered across all five faculties at University of Newcastle, Australia. The authors collected and analysed data about students’ experiences of tasks they completed through an anonymous online survey. Findings – Students’ engagement with the task was extremely positive but also highly varied. This diversity of student experience can inform teaching, and in doing so, can support student equity. By understanding what students think hinders or facilitates their learning, and which students have these experiences, instructors are able to make adjustments to their teaching which address both real and perceived issues. Student experience in this study highlighted five very clear themes in relation to the student experience of undertaking online oral communications tasks which all benefit from nuanced responses by the instructor: relevance; capacity; technology; time; and support. Practical implications – Using well-designed OOCATs that diverge from more traditional written assessments can help students successfully engage with course content and develop oral communication skills. The student experience can be used to inform teaching by catering for different student learning styles and experience. Student centred approaches such as this allows instructors to reflect upon the assumptions they hold about their students and how they learn. This understanding can help inform adjustments to teaching approaches to support improved student experience of learning oral communications tasks. Originality/value – The importance of learning oral communication skills in tertiary education is widely acknowledged internationally, however, there is limited research on how to teach these skills online in a way that is student centred. This research makes a contribution toward addressing that gap.

We examined the response of the common brown froglet, Crinia signifera, to recently clearcut forest edges in Tasmanian wet Eucalyptus obliqua forest. We established transects of pitfall traps crossing coupe edges, within coupes, and within mature forest interiors (riparian and non-riparian) at three study sites. Pitfall captures of C. signifera were greatest at the immediate logged forest edge (which corresponded with a firebreak constructed as part of standard clearfell, burn and sow silvicultural practices in Tasmania). Capture rates were lower in both the coupe interior and the immediate unlogged forest edge and declined to negligible numbers in the unlogged forest interior. Edge penetration was estimated to be generally 50–100 m. We suggest that Tasmania’s current management of wet forest may provide additional habitat for C. signifera by changing the age structure of the forest and providing additional forest edge/firebreak habitat. However, C. signifera is common and disturbance tolerant, and thus these findings should not be extrapolated to other Australian frog species that may be disadvantaged by current logging practices.

Fluctuating asymmetry has been proposed as an indicator of environmental stress and population health. However, a notable feature of research examining the relationship between fluctuating asymmetry and population fitness is that of inconsistency. Logging dramatically alters habitat and has the potential to increase or decrease environmental stress. To evaluate the response of fluctuating asymmetry to logging, I conducted research to determine whether fluctuating asymmetry differs in the frog Crinia signifera captured at logged and unlogged sites and if any differences were correlated with body size or body condition. There was a decrease in fluctuating asymmetry but also a decrease in body size and body condition as a result of logging. I also investigated whether any relationship existed between the subtle asymmetry of individuals and the following indicators of fitness: clutch size, clutch mass, average egg mass, testes size, body size and body condition. There was no significant relationship between subtle asymmetry and the fitness indicators.

Past research has determined the habitat requirements of amphibian species predominantly from presence/absence studies. This study tested the hypothesis that relationships between breeding site habitat components, life history traits and fitness may provide a higher resolution of biological data relating to the habitat requirements of amphibian species. We tested this novel approach by using Litoria ewingii as our model species. We correlated larval and metamorph life history traits with habitat variables at 28 small to medium sized ponds within a commercially logged forest in southern Tasmania, Australia. To avoid larval mortality due to pond desiccation, L. ewingii laid eggs and metamorphosed earlier in smaller ponds. Snout vent length at metamorphosis increased with elevation and metamorphosis was earlier in less shaded ponds. Breeding ponds that maximised the fitness of L. ewingii were higher elevation ponds with reduced shading, steeper bank slopes and reduced pond isolation. The findings of the study equip land managers with a greater ecological understanding of ecosystem function in relation to specific species. The methodological approach has broad application to conservation biology where an awareness of the specific habitat requirements of amphibians is critical to successful ecosystem management.
