Ruminant methane is a major contributor to the anthropogenic greenhouse gas inventories of Australia and New Zealand. Direct intervention in the rumen offers one means for controlling ruminant methane emissions. In this respect, acetogenic bacteria (acetogens) normally present in the rumen are of interest because they have the potential to provide an alternative sink for H2, an essential intermediate in the formation of methane. Although little is known about the populations of acetogens in grazing ruminants, studies on ruminants fed diets containing concentrates or conserved forages indicate that the rumen contains a diversity of acetogens and that some of these have the potential to act as hydrogenotrophs in place of methanogens. This paper describes the current understanding of ruminal acetogens and outlines potential applications of acetogens in methane mitigation strategies. Strategies which use acetogens to outcompete and displace methanogens are considered less likely to be successful than strategies which use acetogens to maintain low H2 levels in the rumen following suppression of methanogens. However, the former cannot be completely discounted at present.

William Smyth, unable to get work in a New Zealand museum, ran a commercial taxidermy business at Caversham, Dunedin, from about 1873 to 1911 or 1912. His two decades of correspondence with Thomas Frederic Cheeseman at the Auckland Museum provide a case study of Smyth's professional interaction with one of New Zealand's main museums. We have used this and other sources to paint a picture of Smyth's activities and achievements during a time when there was great interest in New Zealand birds but few local taxidermists to preserve their bodies. Besides the Auckland Museum, Smyth supplied specimens to various people with museum connections, including Georg Thilenius (Germany) and Walter Lawry Buller (New Zealand). Smyth was probably self-taught, and his standards of preparation and labelling were variable, but he left a legacy for the historical documentation of New Zealand ornithology by the large number of his bird specimens that now reside in public museum collections in New Zealand and elsewhere.

This paper deals with state of the art risk and resilience calculations for industrial plants. Resilience is a top priority issue on the agenda of societies due to climate change and the all-time demand for human life safety and financial robustness. Industrial plants are highly complex systems containing a considerable number of equipment such as steel storage tanks, pipe rack-piping systems, and other installations. Loss Of Containment (LOC) scenarios triggered by past earthquakes due to failure on critical components were followed by severe repercussions on the community, long recovery times and great economic losses. Hence, facility planners and emergency managers should be aware of possible seismic damages and should have already established recovery plans to maximize the resilience and minimize the losses. Seismic risk assessment is the first step of resilience calculations, as it establishes possible damage scenarios. In order to have an accurate risk analysis, the plant equipment vulnerability must be assessed; this is made feasible either from fragility databases in the literature that refer to customized equipment or through numerical calculations. Two different approaches to fragility assessment will be discussed in this paper: (i) code-based Fragility Curves (FCs); and (ii) fragility curves based on numerical models. A carbon black process plant is used as a case study in order to display the influence of various fragility curve realizations taking their effects on risk and resilience calculations into account. Additionally, a new way of representing the total resilience of industrial installations is proposed. More precisely, all possible scenarios will be endowed with their weighted recovery curves (according to their probability of occurrence) and summed together. The result is a concise graph that can help stakeholders to identify critical plant equipment and make decisions on seismic mitigation strategies for plant safety and efficiency. Finally, possible mitigation strategies, like structural health monitoring and metamaterial-based seismic shields are addressed, in order to show how future developments may enhance plant resilience. The work presented hereafter represents a highly condensed application of the research done during the XP-RESILIENCE project, while more detailed information is available on the project website https://r.unitn.it/en/dicam/xp-resilience.

Change Mitigation

Evidence shows that global climate change is increasing over time, and requires the adoption of a variety of coping methods. As an alternative for conventional electricity systems, renewable energies are considered to be an important policy tool for reducing greenhouse gas emissions, and therefore, they play an important role in climate change mitigation strategies. Renewable energies, however, may also play a crucial role in climate change adaptation strategies because they can reduce the vulnerability of energy systems to extreme events. The paper examines whether policy-makers in Israel tend to focus on mitigation strategies or on adaptation strategies in renewable energy policy discourse. The results indicate that despite Israel’s minor impact on global greenhouse gas emissions, policy-makers focus more on promoting renewable energies as a climate change mitigation strategy rather than an adaptation strategy. These findings shed light on the important role of international influence—which tends to emphasize mitigation over adaptation—in motivating the domestic policy discourse on renewable energy as a coping method with climate change.
