After 160 years of colonial settlement, Christchurch has recently experienced a sequence of devastating earthquakes and seen the need for a widespread de- and re-construction of the central city, as well as, many of the surrounding neighbourhoods and peri-urban satellite settlements. This paper will offer a view of the opportunities and restrictions to the post-earthquake re-development of Christchurch as informed by ‘growth machine’ theory. A case study investigating an illegal dump in central Christchurch will be used to assess the applicability of growth machine theory to the current disaster response.
The world experiences a number of disasters each year. Following a disaster, the affected area moves to a phase of recovery which involves multiple stakeholders. An important element of recovery is planning the rebuild of the affected environment guided by the legislative framework to which planning is bound to (March & Kornakova, 2017). Yet, there appears to be little research that has investigated the role of planners in a recovery setting and the implications of recovery legislative planning frameworks. This study was conducted to explore the role of the planner in the Canterbury earthquake recovery process in New Zealand and the impact of the Canterbury Earthquake Recovery Act 2011 (CER Act) on planners’ roles and how they operated.
The methodology comprised a combination of document analysis of legislation and related recovery material and 21 semi-structured interviews with key planners, politicians and professionals involved in the recovery. The results suggest that the majority of planners interviewed were affected by the CER Act in their role and how they operated, although institutional context, especially political constraints, was a key factor in determining the degree of impact. It is argued that planners played a key role in recovery and were generally equipped in terms of skills needed in a recovery setting. In order to better utilise planners in post-disaster recovery or disaster risk management, two suggestions are proposed. Firstly, better promote planners and their capabilities to improve awareness of what planners can do. Secondly, educate and build an understanding between central government politicians and planners over each others role to produce better planning outcomes.
Tree mortality is a fundamental process governing forest dynamics, but understanding tree mortality patterns is challenging
because large, long-term datasets are required. Describing size-specific mortality patterns can be especially difficult, due to
few trees in larger size classes. We used permanent plot data from Nothofagus solandri var. cliffortioides (mountain beech)
forest on the eastern slopes of the Southern Alps, New Zealand, where the fates of trees on 250 plots of 0.04 ha were
followed, to examine: (1) patterns of size-specific mortality over three consecutive periods spanning 30 years, each
characterised by different disturbance, and (2) the strength and direction of neighbourhood crowding effects on sizespecific
mortality rates. We found that the size-specific mortality function was U-shaped over the 30-year period as well as
within two shorter periods characterised by small-scale pinhole beetle and windthrow disturbance. During a third period,
characterised by earthquake disturbance, tree mortality was less size dependent. Small trees (,20 cm in diameter) were
more likely to die, in all three periods, if surrounded by a high basal area of larger neighbours, suggesting that sizeasymmetric
competition for light was a major cause of mortality. In contrast, large trees ($20 cm in diameter) were more
likely to die in the first period if they had few neighbours, indicating that positive crowding effects were sometimes
important for survival of large trees. Overall our results suggest that temporal variability in size-specific mortality patterns,
and positive interactions between large trees, may sometimes need to be incorporated into models of forest dynamics.
Question: Does canopy tree regeneration response to different large disturbances vary with soil drainage? Location: Old-growth conifer (Dacrydium and Dacrycarpus), angiosperm (Nothofagus and Weinmannia) rain forest, Mount Harata, South Island, New Zealand. Methods: Trees were aged (1056 cores) to reconstruct stand history in 20 (0.12 - 0.2 ha) plots with different underlying drainage. Spatial analyses of an additional 805 tree ages collected from two (0.3 - 0.7 ha) plots were conducted to detect patchiness for five canopy tree species. Microsite preferences for trees and saplings were determined. Results: There were clear differences in species regeneration patterns on soils with different drainage. Conifer recruitment occurred infrequently in even-aged patches (> 1000 m²) and only on poorly drained soils. Periodic Nothofagus fusca and N. menziesii recruitment occurred more frequently in different sized canopy openings on all soils. Weinmannia recruitment was more continuous on all soils reflecting their greater relative shade-tolerance. Distinct periods of recruitment that occurred in the last 400 years matched known large disturbances in the region. These events affected species differently as soil drainage varied. Following earthquakes, both conifers and N. menziesii regenerated on poorly drained soils, while Nothofagus species and Weinmannia regenerated on well-drained soils. However, Dacrydium failed to regenerate after patchy storm damage in the wetter forest interior; instead faster-growing N. fusca captured elevated microsites caused by uprooting. Conclusions: Underlying drainage influenced species composition, while variation in the impacts of large disturbance regulated relative species abundances on different soils.
Disasters are often followed by a large-scale stimulus supporting the economy through the built environment, which can last years. During this time, official economic indicators tend to suggest the economy is doing well, but as activity winds down, the sentiment can quickly change. In response to the damaging 2011 earthquakes in Canterbury, New Zealand, the regional economy outpaced national economic growth rates for several years during the rebuild. The repair work on the built environment created years of elevated building activity. However, after the peak of the rebuilding activity, as economic and employment growth retracts below national growth, we are left with the question of how the underlying economy performs during large scale stimulus activity in the built environment. This paper assesses the performance of the underlying economy by quantifying the usual, demand-driven level of building activity at this time. Applying an Input–Output approach and excluding the economic benefit gained from the investment stimulus reveals the performance of the underlying economy. The results reveal a strong growing underlying economy, and while convergence was expected as the stimulus slowed down, the results found that growth had already crossed over for some time. The results reveal that the investment stimulus provides an initial 1.5% to 2% growth buffer from the underlying economy before the growth rates cross over. This supports short-term economic recovery and enables the underlying economy to transition away from a significant rebuild stimulus. Once the growth crosses over, five years after the disaster, economic growth in the underlying economy remains buoyant even if official regional economic data suggest otherwise.
It is no secret that there is a problem with the suburb of Aranui. Developed in the 1950s,
Aranui and neighbouring Wainoni are an example of the large-scale, state-funded
subdivisions of the time, yet, unlike similar developments in the North Island, they have
received little to no attention from researchers. In light of the recent Canterbury
earthquakes, this dissertation aims to trace the evolution of these suburbs until the 1970s
and act as the first stage of a more comprehensive review of state housing and the
Aranui/Wainoni area. By critically reviewing existing literature on state housing and housing
policy in New Zealand, as well as undertaking archival research, this dissertation addresses
the international influences on state housing in New Zealand generally and the development
of the Aranui and Wainoni area more specifically in order to provide a foundation for
answering the question, "What went so wrong?"
Aotearoa New Zealand’s population has grown rapidly from 3.85 million in 2000, to 5 million in 2020. Ethnic diversity has consequently increased. Territorial Authorities (TAs) undertaking statutory consultation and wider public engagement processes need to respond to increased diversity and foster inclusivity. Inclusivity is necessary to facilitate a greater understanding of TA statutory functions, as well as to encourage awareness and participation in annual planning processes, and resource management plans and consents. We examined perceptions, and experiences, of planning within the ethnic Chinese immigrant population of Christchurch. The Chinese ethnic group is a significant part of the city’s population and is in itself derived from diverse cultural and language backgrounds. We surveyed 111 members of this community, via social media and in person, to identify environmental and planning issues of concern to them. We sought to ascertain their previous engagement with planning processes and to gauge their willingness for future involvement. We also undertook a small number of semi-structured interviews with Chinese immigrants to explore their experiences with planning in more detail. Results showed only 6% of respondents had been engaged in any planning processes, despite only 20% being unwilling to participate. We analysed these responses by gender, age, visa category, and length of time resident in Christchurch. Notwithstanding the low level of reported engagement, earthquake recovery (70% of respondents) along with water quality, transport, and air quality were the most important issues of concern. However, there was a general lack of awareness of the ability to make public submissions on these and other issues, and of the statutory responsibilities of TAs. We discuss possible explanations and provide several suggestions for TAs to increase awareness and to improve engagement. This includes further research to assist in identifying the nature of barriers as well as the effectiveness of trialling different solutions.
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).
High rise developments dominate skylines and are contentious in many low rise urban environments. Christchurch is no exception and its residents have historically been vocal in articulating their opinions on matters they care about, especially in regard to projects they perceive will ruin their ‘garden city’. At the turn of the millennium, developers were preparing yet another proposal which would get the tongues wagging in Christchurch with the development of the former Ferrymead Tavern site on Ferry Road. The planning process was a long and antagonistic one with many individuals viewing the built towers with a look of ‘disgust’ and discontent. In an ironic twist, the seismic activity in Christchurch over the last few years which has had major implications for a range of planning issues, incrementally led to the death of highly controversial Ferrymead ‘Water’s Edge’ Apartments.
Since the 2010/11 Canterbury earthquakes, Akaroa has been hosting the majority of cruise ship
arrivals to Canterbury. This amounts to approximately 70-74 days per season, when between 2,000-
4,000 persons come ashore between 9am and 4pm when in port. This increased level of cruise ship
arrivals has had significant impacts, both beneficial and detrimental, on Akaroa. Attitudes within the
Akaroa community to hosting cruise ship arrivals appear to be divided, and has led to public debate
in Akaroa about the issue. In response to this situation, Christchurch and Canterbury Tourism (CCT)
commissioned this research project to assess the impact of cruise ship tourism on the Akaroa
community.This research was commissioned and funded by Christchurch and Canterbury Tourism (CCT).
The impact of the Canterbury earthquake sequence of 2010-12 and its aftermath has been enormous. This inventory lists some of the thousands of community-led groups and initiatives across the region that have developed or evolved as a result of the quake. This inventory is the third such inventory to have been produced. The Christchurch Earthquake Activity Inventory was released by Landcare Research in May 2011, three months after the devastating 22 February 2011 earthquake. The second inventory, entitled An Inventory of Community-led Recovery Initiatives in Canterbury, was collated by Bailey Peryman and Dr Suzanne Vallance (Lincoln University) approximately one year after the February earthquake. The research for this third inventory was undertaken over a four month period from June to September 2013, and was conducted primarily through online searches.This research was undertaken with funding support from the Natural Hazards Platform and GNS, New Zealand.
This paper identifies and analyses the networks of support for tangata whaiora (mental health clients) utilising a kaupapa Mäori health service following the Ötautahi/Christchurch earthquakes
in Aotearoa New Zealand from 2010 to 2012. Semi- structured interviews were undertaken with 39 participants, comprising clients (Mäori and Päkehä), staff, managers and board members of a kaupapa Mäori provider in the city. Selected quotes are presented alongside a social network analysis of the support accessed by all participants. Results show the signifi cant isolation of both Mäori and Päkehä mental health clients post- disaster and the complexity of individuals and collectives dealing with temporally and spatially overlapping hazards and disasters at personal, whänau and community level.
Geographically isolated communities around the world are dependent upon the limited assets in local subsistence economies to generate livelihoods. Locally available resources shape and give identity to unique cultural activities that guarantee individual, family and community livelihood sustainability. The social structure provides community relationship networks, which ensure access to, and availability of, resources over long periods. Resources are utilised in ways that reduces vulnerability, stresses and shocks while ensuring long-term resilience. Preparedness and adaptation are embedded into cultural memory, enabling communities to survive in isolated, remote and harsh conditions. Communities’ cultural memories, storytelling, traditional knowledge, interdependence and unwritten cultural norms that build resilience to sustain cultures that have limited interactions with the outside world.
This thesis aims to investigate the consequences of transport infrastructure development, mainly of roads, on livelihood strategies of isolated communities in a tourism context in Gilgit-Baltistan, Pakistan. The thesis incorporates a review of literature of transport infrastructure development and livelihood security in reference to vulnerability, resilience and sustainability. Research gaps are identified in terms of transport infrastructure development and tourism, the Sustainable Livelihood Approach, resilience and sustainability. The fieldwork was undertaken using qualitative research methods. Ninety-eight participants were interviewed using open-ended semi-structured interview questions to get an in-depth understanding of livelihood systems, livelihood activities and transport infrastructure development within the tourism context.
Gilgit-Baltistan is a disputed mountainous territory in the Asia Subcontinent whose ancient trade routes (silk routes) were severed during the geopolitical upheaval of the partition of the Indian Subcontinent in 1947. An alliance between Pakistan and China resulted in transport infrastructure development of the Karakorum Highway between 1958 and 1978, providing the only road access to the regions isolated communities. Karakoram Highway connects China with Pakistan through Gilgit-Baltistan. Gilgit-Baltistan is going through immense transport infrastructure development, including the China Pakistan Economic Corridor. The road infrastructure is expected to link China and other South Asian and Central Asian countries to the world and provide a direct link for Chinese goods to reach the Persian Gulf. China Pakistan Economic Corridor is part of China’s Belt and Road Initiative project, which aims to improve connectivity and cooperation between 69 Eurasian countries by investing in infrastructure development. Such an immense infrastructural development is expected to enhance the mobility of people, goods and services.
In order to understand the impacts of transport infrastructure development, this thesis has analysed livelihood capital status at macro, and micro levels are examined over two time periods (pre-road and post-road). Results show that sustainable farming practices provided long-term resilience to these geographically isolated communities. Transport infrastructure development has been a significant factor to ensure access and has resulted in changes to social inclusion, socio-political structures and livelihood opportunities with a subsequent dependence upon tourism, imported consumer goods and a monetary economy as people divert valuable farmland to building developments and cash crop monocultures. Gilgit-Baltistan is vulnerable to frequent manmade and natural disasters, such as terrorism, earthquakes and landslides. Shocks impact upon the livelihoods of those affiliated with tourism who are forced to revert to subsistence farming practices and alternative livelihood choices. The dependency on external resources and subsequent loss of the cultural memory and farming techniques has created a vulnerability to the unpredictable shocks and disasters that frequently close the singular access road.
The thesis finally presents the ‘Livelihood Framework for Transport Infrastructure Development and Tourism (LF-TIDT)’ a guiding tool to understand the impacts of transport infrastructure development at micro and macro levels for tourism planning, policy formulation and implementation and management. Attention is drawn to the newly introduced ‘Location: a Meta Capital’ and its importance in terms of geographically isolated communities. The research also highlights that livelihood capitals are not equally essential to achieve sustainable and resilient livelihood outcomes.
A city’s planted trees, the great majority of which are in private gardens, play a fundamental role in shaping a city’s wild ecology, ecosystem functioning, and ecosystem services. However, studying tree diversity across a city’s many thousands of separate private gardens is logistically challenging. After the disastrous 2010–2011 earthquakes in Christchurch, New Zealand, over 7,000 homes were abandoned and a botanical survey of these gardens was contracted by the Government’s Canterbury Earthquake Recovery Authority (CERA) prior to buildings being demolished. This unprecedented access to private gardens across the 443.9 hectares ‘Residential Red Zone’ area of eastern Christchurch is a unique opportunity to explore the composition of trees in private gardens across a large area of a New Zealand city. We analysed these survey data to describe the effects of housing age, socio-economics, human population density, and general soil quality, on tree abundance, species richness, and the proportion of indigenous and exotic species. We found that while most of the tree species were exotic, about half of the individual trees were local native species. There is an increasing realisation of the native tree species values among Christchurch citizens and gardens in more recent areas of housing had a higher proportion of smaller/younger native trees. However, the same sites had proportionately more exotic trees, by species and individuals, amongst their larger planted trees than older areas of housing. The majority of the species, and individuals, of the larger (≥10 cm DBH) trees planted in gardens still tend to be exotic species. In newer suburbs, gardens in wealthy areas had more native trees than gardens from poorer areas, while in older suburbs, poorer areas had more native big trees than wealthy areas. In combination, these describe, in detail unparalleled for at least in New Zealand, how the tree infrastructure of the city varies in space and time. This lays the groundwork for better understanding of how wildlife distribution and abundance, wild plant regeneration, and ecosystem services, are affected by the city’s trees.
The concept of geoparks was first introduced in the first international conference on geoparks held in China in 2004. Here in New Zealand, Kiwis are accustomed to national parks, land reserves, marine reserves, and urban cities and regional parks. The concept of these protected areas has been long-standing in the country, whereas the UNESCO concept of geoparks is still novel and yet to be established in New Zealand.
In this dissertation, I explored the geopark concept for better understanding of its merits and examined the benefits of geotourism attractions as a sustainable economic development strategy to retrieve a declining rural economy. This research is focused on Kaikoura as a case study with geological significance, and emphasizes pre-earthquake existing geological heritages and new existing geological heritages post-earthquake to determine whether the geopark concept is appropriate and what planning framework is available to process this concept proposal should Kaikoura be interested in future.
Disasters are a critical topic for practitioners of landscape architecture. A
fundamental role of the profession is disaster prevention or mitigation
through practitioners having a thorough understanding of known threats. Once we reach the ‘other side’ of a disaster – the aftermath – landscape architecture plays a central response in dealing with its consequences, rebuilding of settlements and infrastructure and gaining an enhanced understanding of the causes of any failures. Landscape architecture must respond not only to the physical dimensions of disaster landscapes but also to the social, psychological and spiritual aspects. Landscape’s experiential potency is heightened in disasters in ways that may challenge and extend the spectrum of emotions. Identity is rooted in landscape, and massive transformation through the impact of a disaster can lead to ongoing psychological devastation. Memory and landscape are tightly
intertwined as part of individual and collective identities, as connections to place and time. The ruptures caused by disasters present a challenge to remembering the lives lost and the prior condition of the landscape, the intimate attachments to places now gone and even the event itself.
Mixed conifer, beech and hardwood forests are relatively common in Aotearoa/New
Zealand, but are not well studied. This thesis investigates the coexistence, regeneration
dynamics and disturbance history of a mixed species forest across an environmental
gradient of drainage and soil development in north Westland.
The aim was to investigate whether conifers, beech and non-beech hardwood species were
able to coexist on surfaces that differed in their underlying edaphic conditions, and if so to understand the mechanisms that influenced their regeneration on both poorly drained and
well drained soils. The site selected was an area of high tree species diversity on a lowland
0.8 km² post-glacial terrace at the base of Mount Harata in the Grey River Valley.
My approach was to use forest stand history reconstruction at two spatial scales: an
intensive within-plot study of stand dynamics (chapter 1) and a whole-landform approach
(chapter 2) that examined whether the dynamics identified at the smaller within-plot scale
reflected larger patterns across the terrace.
In chapter 1, three large permanent plots (0.3-0.7 ha) were placed at different points along
the drainage gradient, one plot situated in each of the mainly well-drained, poorly drained
and very poorly drained areas along the terrace. Information was gathered on species age
and size structures, spatial distributions of tree ages, species interactions, microsite
establishment preferences, patterns of stand mortality, and disturbance history in each plot.
There were differences in stand structure, composition and relative abundance of species
found between the well drained plot and the two poorer drained plots. On the well drained
site conifers were scarce, the beeches Nothofagus fusca and N. menziesii dominated the
canopy, and in the subcanopy the hardwood species Weinmannia racemosa and Quintinia
acutifolia were abundant. As drainage became progressively poorer, the conifers
Dacrydium cupressinum and Dacrycarpus dacrydioides became more abundant and
occupied the emergent tier over a beech canopy. The hardwoods W. racemosa and Q.
acutifolia became gradually less abundant in the subcanopy, whereas the hardwood
Elaeocarpus hookerianus became more so.
In the well drained plot, gap partitioning for light between beeches and hardwoods enabled
coexistence in response to a range of different sized openings resulting from disturbances
of different extent. In the two more poorly drained plots, species also coexisted by
partitioning microsite establishment sites according to drainage.
There were several distinct periods where synchronous establishment of different species
occurred in different plots, suggesting there were large disturbances: c. 100yrs, 190-200
yrs, 275-300 yrs and 375-425 yrs ago. Generally after the same disturbance, different
species regenerated in different plots reflecting the underlying drainage gradient. However,
at the same site after different disturbances, different sets of species regenerated,
suggesting the type and extent of disturbances and the conditions left behind influenced
species regeneration at some times but not others. The regeneration of some species (e.g.,
N. fusca in the well-drained plot, and Dacrydium in the poorer drained plots) was periodic
and appeared to be closely linked to these events. In the intervals between these
disturbances, less extensive disturbances resulted in the more frequent N. menziesii and
especially hardwood regeneration. The type of tree death caused by different disturbances
favoured different species, with dead standing tree death favouring the more shade-tolerant
N. menziesii and hardwoods, whereas uprooting created a mosaic of microsite conditions
and larger gap sizes that enabled Dacrycarpus, N. fusca and E. hookerianus to maintain
themselves in the poorly drained areas.
In chapter 2, 10 circular plots (c. 0.12 ha) were placed in well drained areas and 10
circular plots (c. 0.2 ha) in poorly drained plots to collect information on species
population structures and microsite preferences. The aims were to reconstruct species'
regeneration responses to a range of disturbances of different type and extent across the
whole terrace, and to examine whether there were important differences in the effects of
these disturbances.
At this landform scale, the composition and relative abundances of species across the
drainage gradient reflected those found in chapter 1. There were few scattered conifers in well drained areas, despite many potential regeneration opportunities created from a range
of different stand destroying and smaller scale disturbances.
Three of the four periods identified in chapter 1 reflected distinct terrace-wide periods of
regeneration 75-100 yrs, 200-275 yrs and 350-450 yrs ago, providing strong evidence of
periodic large, infrequent disturbances that occurred at intervals of 100-200 yrs. These
large, infrequent disturbances have had a substantial influence in determining forest
history, and have had long term effects on forest structure and successional processes.
Different large, infrequent disturbances had different effects across the terrace, with the
variability in conditions that resulted enabling different species to regenerate at different
times. For example, the regeneration of distinct even-aged Dacrydium cohorts in poorly
drained areas was linked to historical Alpine Fault earthquakes, but not to more recent
storms. The variation in the intensity of different large, infrequent disturbances at different
points along the environmental drainage gradient, was a key factor influencing the scale of
impacts. In effect, the underlying edaphic conditions influenced species composition along
the drainage gradient and disturbance history regulated the relative abundances of species.
The results presented here further emphasise the importance of large scale disturbances as a
mechanism that allows coexistence of different tree species in mixed forest, in particular
for the conifers Dacrydium, Dacrycarpus and the beech N. fusca, by creating much of the
environmental variation to which these species responded. This study adds to our
understanding of the effects of historical earthquakes in the relatively complex forests of
north Westland, and further illustrates their importance in the Westland forest landscape as
the major influential disturbance on forest pattern and history.
These results also further develop the 'two-component' model used to describe
conifer/angiosperm dynamics, by identifying qualitative differences in the impacts of
different large, infrequent disturbances across an environmental gradient that allowed for
coexistence of different species. In poorer drained areas, these forests may even be thought
of as 'three-component' systems with conifers, beeches and hardwoods exhibiting key
differences in their regeneration patterns after disturbances of different type and extent, and
in their microsite preferences.
Planning in New Zealand in 2014 has largely been dominated by housing and urban development, potential local government and legislative reforms, and water issues. This volume’s peer reviewed research, which combines Issues 1 and 2, focuses on these issues, but with perspectives and issues that are outside the mainstream. In our lead research article, John Ryks and his co-authors review the opportunities from Treaty settlements and legislative provisions and challenges for Māori participation in urban development, such as the balancing of matawaka and mana whenua perspectives. Water issues are picked up by Ronlyn Duncan and Phil Holland who each take constructively critical views toward some currently well-regarded approaches to resolutions. We have reflective and somewhat contrasting contributions from two highly respected semi-retired planners, Malcolm Douglass (FNZPI) and Derek Hall, that challenge aspects of New Zealand’s current approach to planning. In our outreach part of this Volume we include the response of some political parties to questions put to them about planning by LPR team member Nicole Read. Finally, Lincoln University appears to have turned a corner after the earthquakes, at least in the planning programmes.
The disastrous earthquakes that struck Christchurch in 2010 and 2011 seriously impacted on the individual and collective lives of Māori residents. This paper continues earlier, predominantly qualitative research on the immediate effects on Māori by presenting an analysis of a survey carried out 18 months after the most destructive event, on 22 February 2011. Using a set-theoretic approach, pathways to Māori resilience are identified, emphasising the combination of whānau connectivity and high incomes in those who have maintained or increased their wellbeing post-disaster. However, the results show that if resilience is used to describe a “bounce back” in wellbeing, Māori are primarily enduring the post-disaster environment. This endurance phase is a precursor to any resilience and will be of much longer duration than first thought. With continued uncertainty in the city and wider New Zealand economy, this endurance may not necessarily lead to a more secure environment for Māori in the city.
The Kaikoura earthquake in November 2016 highlighted the vulnerability of New Zealand’s rural communities to locally-specific hazard events, which generate regional and national scale impacts. Kaikoura was isolated with significant damage to both the east coast road (SH1) and rail corridor, and the Inland Road (Route 70). Sea bed uplift along the coast was significant – affecting marine resources and ocean access for marine operators engaged in tourism and harvesting, and recreational users. While communities closest to the earthquake epicentre (e.g., Kaikoura, Waiau, Rotherham and Cheviot) suffered the most immediate earthquake damage, the damage to the transport network, and the establishment of an alternative transport route between Christchurch and Picton, has significantly impacted on more distant communities (e.g., Murchison, St Arnaud and Blenheim). There was also considerable damage to vineyard infrastructure across the Marlborough region and damage to buildings and infrastructure in rural settlements in Southern Marlborough (e.g., Ward and Seddon).
Creativity that is driven by a need for physical or economic survival, which disasters are likely to inspire, raises the question of whether such creativity fits with conventional theories and perspectives of creativity. In this paper we use the opportunity afforded by the 2010-2013 Christchurch, New Zealand earthquakes to follow and assess the creative practices and responses of a number of groups and individuals. We use in-depth interviews to tease out motivations and read these against a range of theoretical propositions about creativity. In particular, we focus on the construct of “elite panic” and the degree to which this appeared to be evident in the Christchurch earthquakes context. Bureaucratic attempts to control or limit creativity were present but they did not produce a completely blanket dampening effect. Certain individuals and groups seemed to be pre-equipped to navigate or ignore potential blocks to creativity. We argue, using Geir Kaufmann’s novelty-creativity matrix and aspects of Teresa Amabile’s and Michael G. Pratt’s revised componential theory of creativity that a special form of disaster creativity does exist.
On 4 September 2010, a 7.1 magnitude earthquake struck near Darfield, 40 kilometres west of Christchurch, New Zealand. The quake caused significant damage to land and buildings nearby, with damage extending to Christchurch city. On 22 February 2011, a 6.3 magnitude earthquake struck Christchurch, causing extensive and significant damage across the city and with the loss of 185 lives. Years on from these events, occasional large aftershocks continue to shake the region.
Two main entomological collections were situated within close proximity to the 2010/11 Canterbury earthquakes. The Lincoln University Entomology Research Collection, which is housed on the 5th floor of a 7 storey building, was 27.5 km from the 2010 Darfield earthquake epicentre. The Canterbury Museum Entomology Collection, which is housed in the basement of a multi-storeyed heritage building, was 10 km from the 2011 Christchurch earthquake epicentre. We discuss the impacts of the earthquakes on these collections, the causes of the damage to the specimens and facilities, and subsequent efforts that were made to prevent further damage in the event of future seismic events. We also discuss the wider need for preparedness against the risks posed by natural disasters and other catastrophic events.
The Christchurch earthquakes brought to an abrupt halt a process of adaptive reuse and gentrification that was underway in the south eastern corner of the central business district. The retail uses that were a key to the success of this area pre-earthquake could be characterised as small, owner operated, quirky, bohemian, chaotic and relatively low rent. This research reports on the progress of a long term, comprehensive case study that follows the progress of these retailers both before and after the earthquakes. Findings include the immediate post-earthquake intentions to resume business in the same location as soon as possible were thwarted by government imposed cordons of the CBD that were only lifted nearly three years later. But, businesses were resilient and generally reinvented themselves quickly in alternative suburban locations where government “rebuild” restrictions were absent. It remains to be seen if this type of retail will ever return to the CBD as government imposed plans and the rents demanded for retail space in new buildings appear to preclude small owner-operated businesses.
As a result of the Christchurch Earthquake that occurred on 22nd February 2011 and the resultant loss of life and widespread damage, a Royal Commission of Enquiry was convened in April 2011. The Royal Commission recommended a number of significant changes to the regulation of earthquake prone building in New Zealand. Earthquake prone buildings are buildings that are deemed to be of insufficient strength to perform adequately in a moderate earthquake. In response to the Royal Commission recommendations the New Zealand Government carried out a consultative process before announcing proposed changes to the building regulations in August 2013. One of the most significant changes is the imposition of mandatory strengthening requirements for earthquake prone buildings on a national basis. This will have a significant impact on the urban fabric of most New Zealand towns and cities. The type of traditional cost benefit study carried out to date fails to measure these impacts and this paper proposes an alternative methodology based on the analysis of land use data and rating valuations. This methodology was developed and applied to a small provincial town in the form of a case study. The results of this case study and the methodology used are discussed in this paper.
Though there is a broad consensus that communities play a key role in disaster response and recovery, most of the existing work in this area focuses on the activities of donor agencies, formal civil defence authorities, and local/central government. Consequently, there is a paucity of research addressing the on-going actions and activities undertaken by communities and ‘emergent groups’ , particularly as they develop after the immediate civil defence or ‘response’ phase is over.
In an attempt to address this gap, this inventory of community-led recovery initiatives was undertaken approximately one year after the most devastating February 2011 earthquake. It is part of on-going project at Lincoln University documenting – and seeking a better understanding of -
various emergent communities’ roles in recovery, their challenges, and strategies for overcoming them. This larger project also seeks to better understand how collaborative work between informal and formal recovery efforts might be facilitated at different stages of the process.
This inventory was conducted over the December 2011 – February 2012 period and builds on Landcare Research’s Christchurch Earthquake Activity Inventory which was a similar snapshot taken in April 2011. The intention behind conducting this updated inventory is to gain a longitudinal perspective of how community-led recovery activities evolve over time.

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.
Please contact supervisor Lin Roberts at Lincoln University to request a copy of this dissertation to read.Cities around the world are becoming greener, with many striving to make their cities as green as possible. Christchurch was devastated by an Earthquake in 2011, which resulted in many fatalities. Though this impacted the city negatively, this sad event was used as an opportunity for the broken city to become a better one. The Christchurch City Council (CCC) ran an exercise called ‘Share an Idea’, which asked the public what they wanted the new city to look like. The main theme extrapolated by researchers was that people wanted the city to be greener. A draft plan was created by the CCC but was deemed not good enough and replaced by a new plan called the Blueprint Plan created by the government. Through the process of public consultation to the finalized plan and the implementation of the finalized plan, there were many changes made to the inclusion of nature into Central Christchurch’s urban regeneration. The aim of this research is to assess the role of nature in the urban regeneration of Christchurch, by evaluating the recovery process, and comparing the level of greenness the public wanted by looking at what they said in Share an Idea, and then seeing how that translated into the proposed plans, and then finally looking at what is being implemented.
There is a critical strand of literature suggesting that there are no ‘natural’ disasters (Abramovitz, 2001; Anderson and Woodrow, 1998; Clarke, 2008; Hinchliffe, 2004). There are only those that leave us – the people - more or less shaken and disturbed. There may be some substance to this; for example, how many readers recall the 7.8 magnitude earthquake centred in Fiordland in July 2009? Because it was so far away from a major centre and very few people suffered any consequences, the number is likely to be far fewer than those who remember (all too vividly) the relatively smaller 7.1 magnitude Canterbury quake of September 4th 2010 and the more recent 6.3 magnitude February 22nd 2011 event.
One implication of this construction of disasters is that seismic events, like those in Canterbury, are as much socio-political as they are geological. Yet, as this paper shows, the temptation in recovery is to tick boxes and rebuild rather than recover, and to focus on hard infrastructure rather than civic expertise and community involvement. In this paper I draw upon different models of community engagement and use Putnam’s (1995) notion of ‘social capital’ to frame the argument that ‘building bridges’ after a disaster is a complex blend of engineering, communication and collaboration. I then present the results of a qualitative research project undertaken after the September 4th earthquake. This research helps to illustrate the important connections between technical rebuilding, social capital, recovery processes and overall urban resilience.
The paper examines community benefits provided by an established community garden following a major earthquake and discusses possible implications for community garden planning and design in disaster-prone cities. Recent studies show that following extreme storm events community gardens can supply food, enhance social empowerment, provide safe gathering spots, and restorative practices, to remind people of normality. However, the beneficial role played by community gardens following earthquakes is less well known. To fill this gap, the study examines the role played by a community garden in Christchurch, New Zealand, following the 2010/2011 Canterbury Earthquakes. The garden's role is evaluated based on a questionnaire-based survey and in-depth interviews with gardeners, as well as on data regarding the garden use before and after the earthquakes. Findings indicate the garden helped gardeners cope with the post-quake situation. The garden served as an important place to de-stress, share experiences, and gain community support. Garden features that reportedly supported disaster recovery include facilities that encourage social interaction and bonding such as central meeting and lunch places and communal working areas.
This thesis investigates landscape disturbance history in Westland since 1350 AD. Specifically, I test the hypothesis that large-magnitude regional episodes of natural disturbance have periodically devastated portions of the landscape and forest, and that these were caused by infrequent earthquakes along the Alpine Fault.
Forest stand history reconstruction was used to determine the timing and extent of erosion and sedimentation events that initiated new forest cohorts in a 1412 ha study area in the Karangarua River catchment, south Westland. Over 85 % of the study area was disturbed sufficiently by erosion/sedimentation since 1350 AD to initiate new forest cohorts. During this time four episodes of catchment-wide disturbance impacted the study area, and these took place about 1825 AD ± 5 years (Ruera episode), 1715 AD ± 5 years (Sparkling episode), 1615 AD ± 5 years (McTaggart episode), and 1445 AD ± 15 years (Junction episode). The three most recent episodes disturbed 10 %, 35-40 % and 32-50 % respectively of the study area. The Junction episode disturbed at least 6 % of the study area, but elimination of evidence by more recent disturbances prevented an upper limit being defined.
The three earliest episodes correspond to the date-ranges for three Alpine Fault earthquakes from geological data, and are the only episodes of disturbance within each date-range. An earthquake cause is also consistent with features of the disturbance record: large portions of the study area were disturbed, disturbance occurred on all types 'of landforms, and terrace surfaces were abandoned upstream of the Alpine Fault. On this basis erosion/sedimentation induced by Alpine Fault earthquakes has disturbed 14-20 % of the land surface in the study area per century. Storms and other non-seismic erosional processes have disturbed 3-4 % per century.
To examine the importance of the Alpine Fault earthquakes to forest disturbance throughout Westland, I collated all available data on conifer stand age structures in the region and identified dates of disturbance events from 55 even-aged cohorts of trees. Three region-wide episodes of forest disturbance since 1350 AD were found in this sample, and these matched the three Alpine Fault earthquake-caused episodes found in the Karangarua. Forest disturbance at these times was widespread across Westland over at least 200 km from Paringa to Hokitika, and originated from both tree fall and erosion processes. This disturbance history can explain the long-observed regional conifer forest pattern in Westland, of a predominance of similar-sized stands of trees and a relative lack of small-sized (young) stands. The many similar-sized stands are a consequence of synchronous forest disturbance and re-establishment accompanying the infrequent Alpine Fault earthquakes, while the dominance of mature stands of trees and relative lack of young small-sized trees in stands is explained by the long lapsed time since the last Alpine Fault earthquake (c. 280 years).
I applied the landscape disturbance history information to the existing geological data to reconstruct the paleoseismicity of the Alpine Fault since 1350 AD. Best estimates for the timing of the most recent three rupture events from these data are 1715 AD ± 5 years, 1615 AD ± 5 years and 1445 AD ± 15 years. Earthquake recurrence intervals were variable, ranging from about 100 years to at least 280 years (the lapsed time since the last event). All three events caused forest and geomorphic disturbance over at least a 200 km section of Fault between the Karangarua and Hokitika Rivers, and were probably single rupture events. Suppressions in cross dated tree-ring chronologies in the western South Island suggest that the last rupture occurred in 1717 AD, and extended as a single rupture from Haupiri to Fiordland, a distance along the Fault of 375 km.
