The term resilience‘’is increasingly being used in a multitude of contexts. Seemingly the latest buzz‘’word, it can mean many things to many people, in many different situations. In a natural hazard context, the terms sustainable planning‘’, and resilience‘planning are now’being used, often interchangeably. This poster provides an overview of resilience and sustainability within a land use planning and natural hazard context, and discusses how they are interrelated in the situation of the earthquake impacted city of Christchurch, New Zealand.
A plan which provides SCIRT with a map for building and sustaining outstanding performance. The first version of this plan was produced on 18 February 2013.
As a result of the Canterbury earthquakes, over 60% of the concrete buildings in the Christchurch Central Business District have been demolished. This experience has highlighted the need to provide guidance on the residual capacity and repairability of earthquake-damaged concrete buildings. Experience from 2010 Chile indicates that it is possible to repair severely damaged concrete elements (see photo at right), although limited testing has been performed on such repaired components. The first phase of this project is focused on the performance of two lightly-reinforced concrete walls that are being repaired and re-tested after damage sustained during previous testing.
The city of Christchurch, New Zealand, incurred significant damage due to a series of earthquakes in 2010 and 2011. The city had, by the late 2010s, regained economic and social normalcy after a sustained period of rebuilding and economic recovery. Through the concerted rebuilding effort, a modern central business district (CBD) with redesigned infrastructure and amenities was developed. The Christchurch rebuild was underpinned by a commitment of urban planners to an open and connected city, including the use of innovative technologies to gather, use and share data. As was the case elsewhere, the COVID-19 pandemic brought about significant disruptions to social and economic life in Christchurch. Border closures, lockdowns, trading limitations and other restrictions on movement led to changes in traditional consumer behaviors and affected the retail sector’s resilience. In this study, we used CBD pedestrian traffic data gathered from various locations to predict changes in retail spending and identify recovery implications through the lens of retail resilience. We found that the COVID-19 pandemic and its related lockdowns have driven a substantive change in the behavioral patterns of city users. The implications for resilient retail, sustainable policy and further research are explored.
A video of a presentation by Jane Murray and Stephen Timms during the Social Recovery Stream of the 2016 People in Disasters Conference. The presentation is titled, "Land Use Recovery Plan: How an impact assessment process engaged communities in recovery planning".The abstract for this presentation reads as follows: In response to the Canterbury earthquakes, the Minister for Canterbury Earthquake Recovery directed Environment Canterbury (Canterbury's regional council) to prepare a Land Use Recovery Plan that would provide a spatial planning framework for Greater Christchurch and aid recovery from the Canterbury earthquakes. The Land Use Recovery Plan sets a policy and planning framework necessary to rebuild existing communities and develop new communities. As part of preparing the plan, an integrated assessment was undertaken to address wellbeing and sustainability concerns. This ensured that social impacts of the plan were likely to achieve better outcomes for communities. The process enabled a wide range of community and sector stakeholders to provide input at the very early stages of drafting the document. The integrated assessment considered the treatment of major land use issues in the plan, e.g. overall distribution of activities across the city, integrated transport routes, housing typography, social housing, employment and urban design, all of which have a key impact on health and wellbeing. Representatives from the Canterbury Health in All Policies Partnership were involved in designing a three-part assessment process that would provide a framework for the Land Use Recovery Plan writers to assess and improve the plan in terms of wellbeing and sustainability concerns. The detail of these assessment stages, and the influence that they had on the draft plan, will be outlined in the presentation. In summary, the three stages involved: developing key wellbeing and sustainability concerns that could form a set of criteria, analysing the preliminary draft of the Land Use Recovery Plan against the criteria in a broad sector workshop, and analysing the content and recommendations of the Draft Plan. This demonstrates the importance of integrated assessment influencing the Land Use Recovery Plan that in turn influences other key planning documents such as the District Plan. This process enabled a very complex document with wide-ranging implications to be broken down, enabling many groups, individuals and organisations to have their say in the recovery process. There is also a range of important lessons for recovery that can be applied to other projects and actions in a disaster recovery situation.
The increase in urban population has required cities to rethink their strategies for minimising greenhouse gas impacts and adapting to climate change. While urban design and planning policy have been guided by principles such as walkability (to reduce the dependence on cars) and green infrastructure (to enhance the quality of open spaces to support conservation and human values), there have been conflicting views on what spatial strategies will best prepare cities for a challenging future. Researchers supporting compact cities based upon public Transit Oriented Development have claimed that walkability, higher density and mixed-uses make cities more sustainable (Owen, 2009) and that, while green spaces in cities are necessary, they are dull in comparison with shopfronts and street vendors (Speck, 2012, p 250). Other researchers claim that green infrastructure is fundamental to improving urban sustainability and attracting public space users with improved urban comfort, consequently encouraging walkability (Pitman and Ely, 2013). Landscape architects tend to assume that ‘the greener the better’; however, the efficiency of urban greenery in relation to urban comfort and urbanity depends on its density, distribution and the services provided. Green infrastructure can take many forms (from urban forests to street trees) and provide varied services (amended microclimate, aesthetics, ecology and so forth). In this paper, we evaluate the relevance of current policy in Christchurch regarding both best practice in green infrastructure and urban comfort (Tavares, 2015). We focus on the Christchurch Blueprint for rebuilding the central city, and critically examine the post-earthquake paths the city is following regarding its green and grey infrastructures and the resulting urban environment. We discuss the performance and appropriateness of the current Blueprint in post-earthquake Christchurch, particularly as it relates to the challenges that climate change is creating for cities worldwide.
The lived reality of the 2010-2011 Canterbury earthquakes and its implications for the Waimakariri District, a small but rapidly growing district (third tier of government in New Zealand) north of Christchurch, can illustrate how community well-being, community resilience, and community capitals interrelate in practice generating paradoxical results out of what can otherwise be conceived as a textbook ‘best practice’ case of earthquake recovery. The Waimakariri District Council’s integrated community based recovery framework designed and implemented post-earthquakes in the District was built upon strong political, social, and moral capital elements such as: inter-institutional integration and communication, participation, local knowledge, and social justice. This approach enabled very positive community outputs such as artistic community interventions of the urban environment and communal food forests amongst others. Yet, interests responding to broader economic and political processes (continuous central government interventions, insurance and reinsurance processes, changing socio-cultural patterns) produced a significant loss of community capitals (E.g.: social fragmentation, participation exhaustion, economic leakage, etc.) which simultaneously, despite local Council and community efforts, hindered community well-being in the long term. The story of the Waimakariri District helps understand how resilience governance operates in practice where multi-scalar, non-linear, paradoxical, dynamic, and uncertain outcomes appear to be the norm that underpins the construction of equitable, transformative, and sustainable pathways towards the future.
The skills agenda has grown in prominence within the construction industry. Indeed, skill shortages have been recognised as a perennial problem the construction industry faces, especially after a major disaster. In the aftermath of the Christchurch earthquakes, small and medium construction companies were at the forefront of rebuilding efforts. While the survival of these companies was seen to be paramount, and extreme events were seen to be a threat to survival, there is a dearth of research centring on their resourcing capacity following a disaster. This research aims to develop workforce resourcing best practice guidelines for subcontractors in response to large disaster reconstruction demands. By using case study methods, this research identified the challenges faced by subcontracting businesses in resourcing Christchurch recovery projects; identified the workforce resourcing strategies adopted by subcontracting businesses in response to reconstruction demand; and developed a best practice guideline for subcontracting businesses in managing the workforce at the organisational and/or project level. This research offers a twofold contribution. First, it provides an overview of workforce resourcing practices in subcontracting businesses. This understanding has enabled the development of a more practical workforce resourcing guideline for subcontractors. Second, it promotes evidence-informed decision-making in subcontractors’ workforce resourcing. Dynamics in workforce resourcing and their multifaceted interactions were explicitly depicted in this research. More importantly, this research provides a framework to guide policy development in producing a sustainable solution to skill shortages and establishing longterm national skill development initiatives. Taken together, this research derives a research agenda that maps under-explored areas relevant for further elaboration and future research. Prospective researchers can use the research results in identifying gaps and priority areas in relation to workforce resourcing.
In the last two decades, the retail sector has experienced unprecedented upheaval, having severe implications for economic development and sustenance of traditional inner-city retail districts. In the city of Christchurch, New Zealand, this effect has been exacerbated by a series of earthquakes in 2010/2011 which destroyed much of the traditional retail precinct of the city. After extensive rebuild activity of the city’s infrastructure, the momentum of retailers returning to the inner city was initially sluggish but eventually gathered speed supported by increased international visitation. In early 2020, the return to retail normality came to an abrupt halt after the emergence of the COVID-19 pandemic. This study uses spending and transaction data to analyze the compounding impact of the earthquake’s aftermath, shift to online shopping, and the retail disruption in the Christchurch central retail precinct because of COVID-19. The findings illustrate how consumers through their spending respond to different types of external shocks, altering their consumption patterns and retail mode (offline and online) to cope with an ever-changing retail landscape. Each event triggers different spending patterns that have some similarities but also stark differences, having implications for a sustainable and resilient retail industry in Christchurch. Implications for urban retail precinct development are also discussed.
A video of a presentation by Richard Conlin during the Community Resilience Stream of the 2016 People in Disasters Conference. The presentation is titled, "Resilience, Poverty, and Seismic Culture".The abstract for this presentation reads as follows: A strategy of resilience is built around the recognition that effective emergency response requires community involvement and mobilization. It further recognizes that many of the characteristics that equip communities to respond most effectively to short term emergencies are also characteristics that build strong communities over the long term. Building resilient communities means integrating our approaches to poverty, community engagement, economic development, and housing into a coherent strategy that empowers community members to engage with each other and with other communities. In this way, resilience becomes a complementary concept to sustainability. This requires an asset-based change strategy where external agencies meet communities where they are, in their own space, and use collective impact approaches to work in partnership. This also requires understanding and assessing poverty, including physical, financial, and social capital in their myriad manifestations. Poverty is not exclusively a matter of class. It is a complex subject, and different communities manifest multiple versions of poverty, which must be respected and understood through the asset-based lens. Resilience is a quality of a community and a system, and develops over time as a result of careful analysis of strengths and vulnerabilities and taking actions to increase competencies and reduce risk situations. Resilience requires maintenance and must be developed in a way that includes practicing continuous improvement and adaptation. The characteristics of a resilient community include both physical qualities and 'soft infrastructure', such as community knowledge, resourcefulness, and overall health. This presentation reviews the experience of some earlier disasters, outlines a working model of how emergency response, resilience, and poverty interact and can be addressed in concert, and concludes with a summary of what the 2010 Chilean earthquake tells us about how a 'seismic culture' can function effectively in communities even when government suffers from unexpected shortcomings.
A video of the keynote presentation by Alexander C. McFarlane during the third plenary of the 2016 People in Disasters Conference. McFarlane is a Professor of Psychiatry at the University of Adelaide and the Heady of the Centre for Traumatic Stress Studies. The presentation is titled, "Holding onto the Lessons Disasters Teach".The abstract for this presentation reads as follows: Disasters are sentinel points in the life of the communities affected. They bring an unusual focus to community mental health. In so doing, they provide unique opportunities for better understanding and caring for communities. However, one of the difficulties in the disaster field is that many of the lessons from previous disasters are frequently lost. If anything, Norris (in 2006) identified that the quality of disaster research had declined over the previous 25 years. What is critical is that a longitudinal perspective is taken of representative cohorts. Equally, the impact of a disaster should always be judged against the background mental health of the communities affected, including emergency service personnel. Understandably, many of those who are particularly distressed in the aftermath of a disaster are people who have previously experienced a psychiatric disorder. It is important that disaster services are framed against knowledge of this background morbidity and have a broad range of expertise to deal with the emerging symptoms. Equally, it is critical that a long-term perspective is considered rather than short-term support that attempts to ameliorate distress. Future improvement of disaster management depends upon sustaining a body of expertise dealing with the consequences of other forms of traumatic stress such as accidents. This expertise can be redirected to co-ordinate and manage the impact of larger scale events when disasters strike communities. This presentation will highlight the relevance of these issues to the disaster planning in a country such as New Zealand that is prone to earthquakes.
A video of a presentation by David Meates, Chief Executive of the Christchurch District Health Board and the West Coast District Health Board, during the first plenary of the 2016 People in Disasters Conference. The presentation is titled, "Local System Perspective".The abstract for this presentation reads as follows: The devastating Canterbury earthquakes of 2010 and 2011 have resulted in challenges for the people of Canterbury and have altered the population's health needs. In the wake of New Zealand's largest natural disaster, the health system needed to respond rapidly to changing needs and damaged infrastructure in the short-term in the context of developing sustainable long-term solutions. Canterbury was undergoing system transformation prior to the quakes, however the horizon of transformation was brought forward post-quake: 'Vision 2020' became the vision for now. Innovation was enabled as people working across the system addressed new constraints such as the loss of 106 acute hospital beds, 635 aged residential care beds, the loss of general practices and pharmacies as well as damaged non-government organisation sector. A number of new integration initiatives (e.g. a shared electronic health record system, community rehabilitation for older people, community falls prevention) and expansion of existing programs (e.g. acute demand management) were focused on supporting people to stay well in their homes and communities. The system working together in an integrated way has resulted in significant reductions in acute health service utilisation in Canterbury. Acute admission rates have not increased and remain significantly below national rates and the number of acute and rehabilitation bed days have fallen since the quakes, with these trends most evident among older people. However, health needs frequently reported in post-disaster literature have created greater pressures on the system. In particular, an escalating number of people facing mental health problems and coping with acute needs of the migrant rebuild population provide new challenges for a workforce also affected by the quakes. The recovery journey for Canterbury is not over.
We examined the stratigraphy of alluvial fans formed at the steep range front of the Southern Alps at Te Taho, on the north bank of the Whataroa River in central West Coast, South Island, New Zealand. The range front coincides with the Alpine Fault, an Australian-Pacific plate boundary fault, which produces regular earthquakes. Our study of range front fans revealed aggradation at 100- to 300-year intervals. Radiocarbon ages and soil residence times (SRTs) estimated by a quantitative profile development index allowed us to elucidate the characteristics of four episodes of aggradation since 1000 CE. We postulate a repeating mode of fan behaviour (fan response cycle [FRC]) linked to earthquake cycles via earthquake-triggered landslides. FRCs are characterised by short response time (aggradation followed by incision) and a long phase when channels are entrenched and fan surfaces are stable (persistence time). Currently, the Te Taho and Whataroa River fans are in the latter phase. The four episodes of fan building we determined from an OxCal sequence model correlate to Alpine Fault earthquakes (or other subsidiary events) and support prior landscape evolution studies indicating ≥M7.5 earthquakes as the main driver of episodic sedimentation. Our findings are consistent with other historic non-earthquake events on the West Coast but indicate faster responses than other earthquake sites in New Zealand and elsewhere where rainfall and stream gradients (the basis for stream power) are lower. Judging from the thickness of fan deposits and the short response times, we conclude that pastoral farming (current land-use) on the fans and probably across much of the Whataroa River fan would be impossible for several decades after a major earthquake. The sustainability of regional tourism and agriculture is at risk, more so because of the vulnerability of the single through road in the region (State Highway 6).
A video of a presentation by Professor David Johnston during the fourth plenary of the 2016 People in Disasters Conference. Johnston is a Senior Scientist at GNS Science and Director of the Joint Centre for Disaster Research in the School of Psychology at Massey University. The presentation is titled, "Understanding Immediate Human Behaviour to the 2010-2011 Canterbury Earthquake Sequence, Implications for injury prevention and risk communication".The abstract for the presentation reads as follows: The 2010 and 2011 Canterbury earthquake sequences have given us a unique opportunity to better understand human behaviour during and immediately after an earthquake. On 4 September 2010, a magnitude 7.1 earthquake occurred near Darfield in the Canterbury region of New Zealand. There were no deaths, but several thousand people sustained injuries and sought medical assistance. Less than 6 months later, a magnitude 6.2 earthquake occurred under Christchurch City at 12:51 p.m. on 22 February 2011. A total of 182 people were killed in the first 24 hours and over 7,000 people injured overall. To reduce earthquake casualties in future events, it is important to understand how people behaved during and immediately after the shaking, and how their behaviour exposed them to risk of death or injury. Most previous studies have relied on an analysis of medical records and/or reflective interviews and questionnaire studies. In Canterbury we were able to combine a range of methods to explore earthquake shaking behaviours and the causes of injuries. In New Zealand, the Accident Compensation Corporation (a national health payment scheme run by the government) allowed researchers to access injury data from over 9,500 people from the Darfield (4 September 2010) and Christchurch (22 February 2011 ) earthquakes. The total injury burden was analysed for demography, context of injury, causes of injury, and injury type. From the injury data inferences into human behaviour were derived. We were able to classify the injury context as direct (immediate shaking of the primary earthquake or aftershocks causing unavoidable injuries), and secondary (cause of injury after shaking ceased). A second study examined people's immediate responses to earthquakes in Christchurch New Zealand and compared responses to the 2011 earthquake in Hitachi, Japan. A further study has developed a systematic process and coding scheme to analyse earthquake video footage of human behaviour during strong earthquake shaking. From these studies a number of recommendations for injury prevention and risk communication can be made. In general, improved building codes, strengthening buildings, and securing fittings will reduce future earthquake deaths and injuries. However, the high rate of injuries incurred from undertaking an inappropriate action (e.g. moving around) during or immediately after an earthquake suggests that further education is needed to promote appropriate actions during and after earthquakes. In New Zealand - as in US and worldwide - public education efforts such as the 'Shakeout' exercise are trying to address the behavioural aspects of injury prevention.
