Abstract: Hydrogen‐oxidising bacteria play a key role in maintaining the composition of gases within the atmosphere and are ubiquitous in agricultural soils. While studies have shown that hydrogen accumulates in soil surrounding legume nodules and the soil surface, soils as a whole act as a net sink for hydrogen, raising questions about how hydrogen is internally recycled by soils. Can the energy derived from hydrogen oxidation be directly funnelled into plants to promote their growth or does it only act as a booster for other plant‐growth promoting bacteria? Moreover, while the fertilisation effect of hydrogen on plants has previously been shown to be beneficial, questions remain about the upper limit of hydrogen uptake by plants before it becomes detrimental. Agricultural practices such as fertilisation may impact the balance of hydrogen‐oxidisers and hydrogen‐producers in these ecosystems, potentially having detrimental effects on not only agricultural land but also global biogeochemical cycles. In this perspectives piece, we highlight the importance of understanding the contribution of hydrogen to agricultural soils and the effects of agricultural practices on the ability for bacteria to cycle hydrogen in agricultural soils. We propose a framework to gain better insights into microbial hydrogen cycling within agroecosystems, which could contribute to the development of new agricultural biotechnologies.

Abstract: To survive and thrive in a crisis requires crisis management teams (CMTs) to make sound strategic decisions. This paper examines the perceptions of CMTs from a group of nonresponse organisations to identify dimensions of the strategic decision‐making process during a crisis management exercise. The paper draws on data collected during a series of exercises with seven Australian government agencies and businesses. Using principal component analysis, this paper outlines four dimensions that are perceived to support strategic decision‐making in this context—psychological safety, critical thinking, managing expectations and adaptive capability. Embedding these dimensions within key systems and processes can provide CMTs with the structure they need to effectively respond to a crisis and enhance organisational resilience.

Abstract: Every year, incident management teams (IMTs) coordinate the response to hundreds of emergency events across Australasia. Larger scale emergencies such as a storms, floods, wildfires, oil spills and chemical explosions can place a lot of pressure on an IMT. Non‐technical skills play a central role in the performance of these teams. This article reviewed the broader non‐technical skills (NTS) literature before focusing on the NTS required for emergency management. It was found that most NTS frameworks share four to five common skill categories, although there were greater differences at the element and behavioural marker level. A variety of issues were identified in the literature that highlight that emergency management is very different from other domains where NTS systems have been developed. The literature on NTS in conjunction with this set of issues was used to develop a proposed NTS framework for emergency IMTs. This framework comprises 7 skill categories (i.e. communication, coordination, cooperation, decision‐making, situation awareness, leadership and coping, stress and fatigue management). The 7 skills can be further delineated into 16 elements and 44 behavioural markers. The framework provides a prototype that can form the basis for further research in this area.
