Disaster preparedness, adaptive politics and lifelong learning: a case of Japan

Preparedness for disaster scenarios is progressively becoming an educational agenda for governments because of diversifying risks and threats worldwide. In disaster-prone Japan, disaster preparedness has been a prioritised national agenda, and preparedness education has been undertaken in both formal schooling and lifelong learning settings. This article examines the politics behind one prevailing policy discourse in the field of disaster preparedness referred to as ‘the four forms of aid’ – ‘kojo [public aid]’, ‘jijo [self-help]’, ‘gojo/kyojo [mutual aid]’. The study looks at the Japanese case, however, the significance is global, given that neo-liberal governments are increasingly having to deal with a range of disaster situations whether floods or terrorism, while implementing austerity measures. Drawing on the theory of the adaptiveness of neo-liberalism, the article sheds light on the hybridity of the current Abe government’s politics: a ‘dominant’ neo-liberal economic approach – public aid and self-help – and a ‘subordinate’ moral conservative agenda – mutual aid. It is argued that the four forms of aid are an effective ‘balancing act’, and that kyojo in particular is a powerful legitimator in the hybrid politics. The article concludes that a lifelong and life-wide preparedness model could be developed in Japan which has taken a social approach to lifelong learning. © 2016 Informa UK Limited, trading as Taylor & Francis Group

Situating preparedness education within public pedagogy

Both ‘disaster preparedness’ and ‘public pedagogy’ have been broadly defined and diversely utilised. Preparedness has been dealt within the disciplines such as civil engineering, sociology of disasters, public health and psychology, rather than education. Recently, inquiries into the learning and teaching of preparedness is increasing in the field of education, and some of them position preparedness education within the field of public pedagogy. However, conceptual discussion as to how and why the two fields are associated has been limited. The primary aim of this paper is to fill this gap by drawing on public pedagogy literature that conceptualises ‘publics’ and ‘pedagogies’. By doing so, the paper attempts to respond to Burdick et al’s call for Problematizing Public Pedagogy.

Zombie pedagogies: the problems with using the undead in public pedagogies for emergencies

The well-known Hollywood ‘zombie’ genre has recently begun to invade programs and training courses in disaster control and emergency prevention. The author explores the consequences of a transfer of an entertainment metaphor into real US military policies. Is it possible that this implies attuning the populace to catastrophies by means of edutainment? And does this, as Preston argues, in some ways ‘de-humanize’ one’s adversaries? The article points to a fatal dialectics and disturbing elements of a post-ethical disposition. This results not only in some sort of inevitable legitimation of the ‘war on terror’ leaving behind all tenets of civil society. It also permits, subcutaneously, to act without restrictions against certain groups as if they were ‘undeads’.

Failure Mechanisms and Local Scour at Coastal Structures induced by Tsunamis

On March 11 2011, an exceptionally large tsunami event was triggered by a massive earthquake offshore, the northeast coast of Japan, which affected coastal infrastructure such as seawalls, coastal dikes and breakwaters in the Tohoku region. Such infrastructure was built to protect against the Level 1 tsunamis that previously hit the region, but not for events as significant as the 2011 Tohoku tsunami, which was categorized as a Level 2 tsunami [Shibayama et al. 2013]. The failure mechanisms of concrete-armoured dikes, breakwaters and seawalls due to Level 2 tsunamis are still not fully understood by researchers and engineers. This paper investigates the failure modes and mechanisms of damaged coastal structures in Miyagi and Fukushima Prefectures, following the authors' post-disaster field surveys carried out between 2011 and 2013. Six significant failure mechanisms were identified for the coastal dikes and seawalls affected by this tsunami: 1) Leeward toe scour failure, 2) Crown armour failure, 3) Leeward slope armour failure, 4) Seaward toe and armour failure, 5) Overturning failure, and 6) Parapet wall failure, in which leeward toe scour being recognized as the major failure mechanism in most surveyed locations. The authors also propose a simple practical mathematical model for predicting the scour depth at the leeward toe of the coastal dikes, by considering the effects of the tsunami hydrodynamics, the soil properties and the type of structure. The key advantage of this model is that it depends entirely on quantities that are measurable in the field. Furthermore this model was further refined by conducting a series of hydraulic model experiments aimed to understand the governing factors of the leeward toe scour failure. Finally, based on the results obtained, key recommendations are given for the design of resilient coastal defence structures that can survive a level 2 tsunami event.
