Throughout 2010 and 2011, the city of Christchurch, New Zealand, suffered a series of devastating earthquakes that caused serious damage to the city. This study examines the effect these earthquakes have had on the sport of swimming in Christchurch. It specifically focuses on three different aspects of the swimming industry: indoor competitive swimming, open water swimming and learning to swim. It reports on the industry prior to the earthquakes before examining the developments subsequent to the shakes. The effects on both facilities and participation numbers were examined. Results showed that many indoor swimming facilities were lost which had significant flow-on effects. In addition, many beaches were out of bounds and almost half of the schools in Canterbury lost the use of their own swimming pools. In terms of participation numbers, results showed that while there was a decrease in the number of indoor competitive swimmers, Canterbury clubs were still highly competitive and their rankings at events either remained similar or bettered during and after the period of the earthquakes. On the other hand, an increase in the number of participants was seen in swimming lessons as temporary pools were constructed and subsidies were offered to cover transport and lesson costs. Open water swimming, however, seems to have been relatively unaffected by the earthquakes.This report was made possible through Lincoln University’s Summer Scholarship programme. The authors would also like to acknowledge those anonymous interviewees who provided some valuable insight into the swimming industry in Christchurch.

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.

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.

Lincoln University was commissioned by the Avon-Otakaro Network (AvON) to estimate the value of the benefits of a ‘recreation reserve’ or ‘river park’ in the Avon River Residential Red Zone (ARRRZ). This research has demonstrated significant public desire and support for the development of a recreation reserve in the Avon River Residential Red Zone. Support is strongest for a unique natural environment with native fauna and flora, healthy wetlands and rivers, and recreational opportunities that align with this vision, such as walking, cycling and water-based sporting and leisure activities. The research also showed support for a reserve that promotes and enables community interaction and wellbeing, and is evident in respondents’ desires for community gardens, regular festivals and markets, and the physical linking of the CBD with eastern suburbs through a green corridor. There is less support for children’s playgrounds, sports fields or open grassed areas, all of which could be considered as more typical of an urban park development. Benefits (willing to pay) to Christchurch residents (excluding tourists) of a recreation reserve could be as high as $35 million each year. Savings to public health costs could be as high as $50.3 million each year. The incorporation or restoration of various ecosystems services, including water quality improvements, flood mitigation and storm water management could yield a further $8.8 million ($19, 600) per hectare/year at 450 ha). Combined annual benefits of a recreational reserve in the ARRRZ are approximately $94.1 million per annum but this figure does not include potentially significant benefits from, for example, tourism, property equity gains in areas adjacent to the reserve, or the effects of economic rejuvenation in the East. Although we were not able to provide costing estimates for park attributes, this study does make available the value of benefits, which can be used as a guide to the scope of expenditure on development of each park attribute.

The earthquakes that struck Ōtautahi/Christchurch began September 2010 and continued throughout2012 with the worse shock being February 22, 2011. The extended ‘seismic event’ radically altered thegeophysical and socio-cultural environments of the city. This working paper presents a broad array of datadescribing the impacts of the disaster on Māori. These data frame the results of small email surveyconducted 18 months after the most destructive February 22, 2011. This survey followed two projectsinvestigating the resilience of Māori to the disaster (Lambert & Mark-Shadbolt, 2011; Lambert & Mark-Shadbolt, 2012; Lambert, Mark-Shadbolt, Ataria, & Black, 2012). Results show that while the termresilience has become common to the point of cliché, the Māori experience thus far is best described asendurance.

The 2010 and 2011 earthquakes have had a devastating impact on the city of Christchurch, New Zealand. The level of destruction has been especially evident in the central business district where it has been estimated over 1000 buildings have already been or will eventually require demolition. Although, contrary to expectations, most of the fatalities were in relatively modern buildings, the Victorian and Edwardian era building stock was especially hard hit in terms of property damage. Unfortunately this era and style of building were also the focus of the most successful inner city revitalisation projects to date. A major research project is now underway examining the impact on the earthquakes on one of these revitalisation areas. The first step is to examine the international literature on similar inner city revitalisation or gentrification areas and in particular the characteristics of owners and occupiers attracted to this type of environment. This is the focus of this paper.

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).

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. Each entry is ordered alphabetically and contact details have been provided where possible. A series of keywords have also been assigned that describe the main attributes of each activity to assist searches within this document.This inventory was supported by the Lincoln University Research Fund and the Royal Society Marsden Fund.

Group case study report prepared for lecturers Ton Buhrs and Roy Montgomery by students of ERST 635 at Lincoln University, 2013.The New Zealand Government’s decision to establish a unitary authority in the Auckland Region has provided much of the context and impetus for this review of current governance arrangements in the Canterbury region, to determine whether or not they are optimal for taking the communities of greater Christchurch into the future. A number of local governance academics, as well as several respected political pundits, have prophesised that the Auckland ‘Super City’ reforms of 2009 will have serious implications and ramifications for local governance arrangements in other major cities, particularly Wellington and Christchurch. Wellington councils have already responded to the possibility of change by undertaking a series of reports on local governance arrangements, as well as a major review led by Sir Geoffrey Palmer, to investigate options for governance reform. Alongside these developments, the Christchurch earthquakes beginning in September 2010 have raised a myriad of new and complex governance issues, which may or may not be able to be addressed under the status quo, while the replacement of Regional Councillors’ with centrally-appointed Commissioners is suggestive of government dissatisfaction with current arrangements. With these things in mind, the research group has considered local government in Canterbury and the greater Christchurch area in the wider governance context. It does not limit discussion to only the structure of local government in Canterbury but rather, as the brief (Appendix 1) indicates, considers more broadly the relationship between central, regional, and local tiers of government, as well as the relationship between local government and local communities.

The recent Christchurch earthquakes provide a unique opportunity to better understand the relationship between pre-disaster social fault-lines and post-disaster community fracture. As a resident of Christchurch, this paper presents some of my reflections on the social structures and systems, activities, attitudes and decisions that have helped different Canterbury ‘communities’ along their road to recovery, and highlights some issues that have, unfortunately, held us back. These reflections help answer the most crucial question asked of disaster scholarship: what can recovery agencies (including local authorities) do - both before and after disaster - to promote resilience and facilitate recovery. This paper – based on three different definitions of resilience - presents a thematic account of the social recovery landscape. I argue that ‘coping’ might best be associated with adaptive capacity, however ‘thriving’ or ‘bounce forward’ versions of resilience are a function of a community’s participative capacity.

Mitigating the cascade of environmental damage caused by the movement of excess reactive nitrogen (N) from land to sea is currently limited by difficulties in precisely and accurately measuring N fluxes due to variable rates of attenuation (denitrification) during transport. This thesis develops the use of the natural abundance isotopic composition of nitrate (δ15N and δ18O of NO₃-) to integrate the spatialtemporal variability inherent to denitrification, creating an empirical framework for evaluating attenuation during land to water NO₃- transfers. This technique is based on the knowledge that denitrifiers kinetically discriminate against 'heavy' forms of both N and oxygen (O), creating a parallel enrichment in isotopes of both species as the reaction progresses. This discrimination can be quantitatively related to NO₃- attenuation by isotopic enrichment factors (εdenit). However, while these principles are understood, use of NO₃- isotopes to quantify denitrification fluxes in non-marine environments has been limited by, 1) poor understanding of εdenit variability, and, 2) difficulty in distinguishing the extent of mixing of isotopically distinct sources from the imprint of denitrification. Through a combination of critical literature analysis, mathematical modelling, mesocosm to field scale experiments, and empirical studies on two river systems over distance and time, these short comings are parametrised and a template for future NO₃- isotope based attenuation measurements outlined. Published εdenit values (n = 169) are collated in the literature analysis presented in Chapter 2. By evaluating these values in the context of known controllers on the denitrification process, it is found that the magnitude of εdenit, for both δ15N and δ18O, is controlled by, 1) biology, 2) mode of transport through the denitrifying zone (diffusion v. advection), and, 3) nitrification (spatial-temporal distance between nitrification and denitrification). Based on the outcomes of this synthesis, the impact of the three factors identified as controlling εdenit are quantified in the context of freshwater systems by combining simple mathematical modelling and lab incubation studies (comparison of natural variation in biological versus physical expression). Biologically-defined εdenit, measured in sediments collected from four sites along a temperate stream and from three tropical submerged paddy fields, varied from -3‰ to -28‰ depending on the site’s antecedent carbon content. Following diffusive transport to aerobic surface water, εdenit was found to become more homogeneous, but also lower, with the strength of the effect controlled primarily by diffusive distance and the rate of denitrification in the sediments. I conclude that, given the variability in fractionation dynamics at all levels, applying a range of εdenit from -2‰ to -10‰ provides more accurate measurements of attenuation than attempting to establish a site-specific value. Applying this understanding of denitrification's fractionation dynamics, four field studies were conducted to measure denitrification/ NO₃- attenuation across diverse terrestrial → freshwater systems. The development of NO₃- isotopic signatures (i.e., the impact of nitrification, biological N fixation, and ammonia volatilisation on the isotopic 'imprint' of denitrification) were evaluated within two key agricultural regions: New Zealand grazed pastures (Chapter 4) and Philippine lowland submerged rice production (Chapter 5). By measuring the isotopic composition of soil ammonium, NO₃- and volatilised ammonia following the bovine urine deposition, it was determined that the isotopic composition of NO₃ - leached from grazed pastures is defined by the balance between nitrification and denitrification, not ammonia volatilisation. Consequently, NO₃- created within pasture systems was predicted to range from +10‰ (δ15N)and -0.9‰ (δ18O) for non-fertilised fields (N limited) to -3‰ (δ15N) and +2‰ (δ18O) for grazed fertilised fields (N saturated). Denitrification was also the dominant determinant of NO₃- signatures in the Philippine rice paddy. Using a site-specific εdenit for the paddy, N inputs versus attenuation were able to be calculated, revealing that >50% of available N in the top 10 cm of soil was denitrified during land preparation, and >80% of available N by two weeks post-transplanting. Intriguingly, this denitrification was driven by rapid NO₃- production via nitrification of newly mineralised N during land preparation activities. Building on the relevant range of εdenit established in Chapters 2 and 3, as well as the soil-zone confirmation that denitrification was the primary determinant of NO₃- isotopic composition, two long-term longitudinal river studies were conducted to assess attenuation during transport. In Chapter 6, impact and recovery dynamics in an urban stream were assessed over six months along a longitudinal impact gradient using measurements of NO₃- dual isotopes, biological populations, and stream chemistry. Within 10 days of the catastrophic Christchurch earthquake, dissolved oxygen in the lowest reaches was <1 mg l⁻¹, in-stream denitrification accelerated (attenuating 40-80% of sewage N), microbial biofilm communities changed, and several benthic invertebrate taxa disappeared. To test the strength of this method for tackling the diffuse, chronic N loading of streams in agricultural regions, two years of longitudinal measurements of NO₃- isotopes were collected. Attenuation was negatively correlated with NO₃- concentration, and was highly dependent on rainfall: 93% of calculated attenuation (20 kg NO₃--N ha⁻¹ y⁻¹) occurred within 48 h of rainfall. The results of these studies demonstrate the power of intense measurements of NO₃- stable isotope for distinguishing temporal and spatial trends in NO₃ - loss pathways, and potentially allow for improved catchment-scale management of agricultural intensification. Overall this work now provides a more cohesive understanding for expanding the use of NO₃- isotopes measurements to generate accurate understandings of the controls on N losses. This information is becoming increasingly important to predict ecosystem response to future changes, such the increasing agricultural intensity needed to meet global food demand, which is occurring synergistically with unpredictable global climate change.

Globally, the maximum elevations at which treelines are observed to occur coincide with a 6.4 °C soil isotherm. However, when observed at finer scales, treelines display a considerable degree of spatial complexity in their patterns across the landscape and are often found occurring at lower elevations than expected relative to the global-scale pattern. There is still a lack of understanding of how the abiotic environment imposes constraints on treeline patterns, the scales at which different effects are acting, and how these effects vary over large spatial extents. In this thesis, I examined abrupt Nothofagus treelines across seven degrees of latitude in New Zealand in order to investigate two broad questions: (1) What is the nature and extent of spatial variability in Nothofagus treelines across the country? (2) How is this variation associated with abiotic variation at different spatial scales? A range of GIS, statistical, and atmospheric modelling methods were applied to address these two questions. First, I characterised Nothofagus treeline patterns at a 15x15km scale across New Zealand using a set of seven, GIS-derived, quantitative metrics that describe different aspects of treeline position, shape, spatial configuration, and relationships with adjacent vegetation. Multivariate clustering of these metrics revealed distinct treeline types that showed strong spatial aggregation across the country. This suggests a strong spatial structuring of the abiotic environment which, in turn, drives treeline patterns. About half of the multivariate treeline metric variation was explained by patterns of climate, substrate, topographic and disturbance variability; on the whole, climatic and disturbance factors were most influential. Second, I developed a conceptual model that describes how treeline elevation may vary at different scales according to three categories of effects: thermal modifying effects, physiological stressors, and disturbance effects. I tested the relevance of this model for Nothofagus treelines by investigating treeline elevation variation at five nested scales (regional to local) using a hierarchical design based on nested river catchments. Hierarchical linear modelling revealed that the majority of the variation in treeline elevation resided at the broadest, regional scale, which was best explained by the thermal modifying effects of solar radiation, mountain mass, and differences in the potential for cold air ponding. Nonetheless, at finer scales, physiological and disturbance effects were important and acted to modify the regional trend at these scales. These results suggest that variation in abrupt treeline elevations are due to both broad-scale temperature-based growth limitation processes and finer-scale stress- and disturbance-related effects on seedling establishment. Third, I explored the applicability of a meso-scale atmospheric model, The Air Pollution Model (TAPM), for generating 200 m resolution, hourly topoclimatic data for temperature, incoming and outgoing radiation, relative humidity, and wind speeds. Initial assessments of TAPM outputs against data from two climate station locations over seven years showed that the model could generate predictions with a consistent level of accuracy for both sites, and which agreed with other evaluations in the literature. TAPM was then used to generate data at 28, 7x7 km Nothofagus treeline zones across New Zealand for January (summer) and July (winter) 2002. Using mixed-effects linear models, I determined that both site-level factors (mean growing season temperature, mountain mass, precipitation, earthquake intensity) and local-level landform (slope and convexity) and topoclimatic factors (solar radiation, photoinhibition index, frost index, desiccation index) were influential in explaining variation in treeline elevation within and among these sites. Treelines were generally closer to their site-level maxima in regions with higher mean growing season temperatures, larger mountains, and lower levels of precipitation. Within sites, higher treelines were associated with higher solar radiation, and lower photoinhibition and desiccation index values, in January, and lower desiccation index values in July. Higher treelines were also significantly associated with steeper, more convex landforms. Overall, this thesis shows that investigating treelines across extensive areas at multiple study scales enables the development of a more comprehensive understanding of treeline variability and underlying environmental constraints. These results can be used to formulate new hypotheses regarding the mechanisms driving treeline formation and to guide the optimal choice of field sites at which to test these hypotheses.

The New Zealand Kellogg Rural Leaders Programme develops emerging agribusiness leaders to help shape the future of New Zealand agribusiness and rural affairs. Lincoln University has been involved with this leaders programme since 1979 when it was launched with a grant from the Kellogg Foundation, USA.On 2 March 1987 the Bay of Plenty region suffered an earthquake of magnitude 6.3 on the Richter scale, centred at Edgecumbe. Severe damage to personal and industrial property and drainage systems occurred. In hindsight, although much of the damage was covered by insurance, loans, public and government contributions, the continuing reconstruction costs have had a tremendous impact financially on individuals and the District as a whole. By highlighting some of these ongoing costs and suggestions of alternatives other Rural communities may be better prepared to lessen the effect of a natural disaster such as the Edgecumbe Earthquake of 1987.

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.

The New Zealand Kellogg Rural Leaders Programme develops emerging agribusiness leaders to help shape the future of New Zealand agribusiness and rural affairs. Lincoln University has been involved with this leaders programme since 1979 when it was launched with a grant from the Kellogg Foundation, USA.At 4.35am on 4th September 2010, Canterbury was hit by an earthquake measuring 7.1 on the Richter scale. On 22nd February 2011 and 13th June 2011 a separate fault line approximately 35km from the first, ruptured to inflict two further earthquakes measuring 6.3 and 6.0 respectively. As a direct result of the February earthquake, 181 people lost their lives. Some commentators have described this series of earthquakes as the most expensive global insurance event of all time. These earthquakes and the more than 7000 associated aftershocks have had a significant physical impact on parts of Canterbury and virtually none on others. The economic, social and emotional impacts of these quakes spread across Canterbury and beyond. Waimakariri district, north of Christchurch, has reflected a similar pattern, with over 1400 houses requiring rebuild or substantial repair, millions of dollars of damage to infrastructure, and significant social issues as a result. The physical damage in Waimakiriri District was predominately in parts of Kaiapoi, and two small beach settlements, The Pines and Kairaki Beach with pockets elsewhere in the district. While the balance of the district is largely physically untouched, the economic, social, and emotional shockwaves have spread across the district. Waimakariri district consists of two main towns, Rangiora and Kaiapoi, a number of smaller urban areas and a larger rural area. It is considered mid-size in the New Zealand local government landscape. This paper will explore the actions and plans of Waimakiriri District Council (WDC) in the Emergency Management Recovery programme to provide context to allow a more detailed examination of the planning processes prior to, and subsequent to the earthquakes. This study looked at documentation produced by WDC, applicable legislation and New Zealand Emergency Management resources and other sources. Key managers and elected representatives in the WOC were interviewed, along with a selection of governmental and nongovernmental agency representatives. The interview responses enable understanding of how central Government and other local authorities can benefit from these lessons and apply them to their own planning. It is intended that this paper will assist local government organisations in New Zealand to evaluate their planning processes in light of the events of 2010/11 in Canterbury and the lessons from WDC.

Prognostic modelling provides an efficient means to analyse the coastal environment and provide effective knowledge for long term urban planning. This paper outlines how the use of SWAN and Xbeach numerical models within the ESRI ArcGIS interface can simulate geomorphological evolution through hydrodynamic forcing for the Greater Christchurch coastal environment. This research followed the data integration techniques of Silva and Taborda (2012) and utilises their beach morphological modelling tool (BeachMM tool). The statutory requirements outlined in the New Zealand Coastal Policy Statement 2010 were examined to determine whether these requirements are currently being complied with when applying the recent sea level rise predictions by the Intergovernmental Panel on Climate Change (2013), and it would appear that it does not meet those requirements. This is because coastal hazard risk has not been thoroughly quantified by the installation of the Canterbury Earthquake Recovery Authority (CERA) residential red zone. However, the Christchurch City Council’s (CCC) flood management area does provide an extent to which managed coastal retreat is a real option. This research assessed the effectiveness of the prognostic models, forecasted a coastline for 100 years from now, and simulated the physical effects of extreme events such as storm surge given these future predictions. The results of this research suggest that progradation will continue to occur along the Christchurch foreshore due to the net sediment flux retaining an onshore direction and the current hydrodynamic activity not being strong enough to move sediment offshore. However, inundation during periods of storm surge poses a risk to human habitation on low lying areas around the Avon-Heathcote Estuary and the Brooklands lagoon similar to the CCC’s flood management area. There are complex interactions at the Waimakariri River mouth with very high rates of accretion and erosion within a small spatial scale due to the river discharge. There is domination of the marine environment over the river system determined by the lack of generation of a distinct river delta, and river channel has not formed within the intertidal zone clearly. The Avon-Heathcote ebb tidal delta aggrades on the innner fan and erodes on the outer fan due to wave domination. The BeachMM tool facilitates the role of spatial and temporal analysis effectively and the efficiency of that performance is determined by the computational operating system.

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.

"Prior to the devastating 2010-2011 Canterbury earthquakes, the city of Christchurch was already exhibiting signs of a housing affordability crisis. The causes and symptoms were similar to those being experienced in Auckland, but the substantial damage to the housing stock caused by the earthquakes added new dimensions and impetus to the problem. Large swathes of the most affordable housing stock in the east of the city were effectively destroyed by the earthquakes. In itself this would have pushed the mean house price upwards, but compounding problems exacerbated the situation. These include the price effects of reduced supply of both rented and owned housing and increased demand from both displaced residents and an influx of rebuild workers. The need for additional temporary housing while repairs were undertaken and the associated insurance pay-outs bidding up rents with improved rental returns leading to increased interest in property investment. Land supply constraints and consenting issues inhibiting the build of new housing and political infighting and uncertainty regarding the future of parts of the city leading to a flight of development activity to peripheral locations and adjoining local authorities. Concerns that the erosion of the city council rating base combined with inadequacy of insurance cover for infrastructure will lead to large rates increases, increased development costs and reduced amenities and services in future years. These and other issuers will be elaborated on in this paper with a view to exploring the way forward for affordable housing Christchurch City."

Following the 2010 and 2011 earthquakes Christchurch is undergoing extensive development on the periphery of the city. This has been driven in part by the large numbers of people who have lost their homes. Prior to the earthquakes, Christchurch was already experiencing placeless subdivisions and now these are being rolled out rapidly thanks to the efficiency of a formula that has been embraced by the Council, developers and the public alike. However, sprawling subdivisions have a number of issues including inefficient land use, limited housing types, high dependence on motor vehicles and low levels of resilience and no sense of place. Sense of place is of particular interest due to its glaring absence from new subdivisions and its growing importance in the literature. Research shows that sense of place has benefits to our feeling of belonging, well-being, and self-identity, particularly following a disaster. It improves the resilience and sustainability of our living environment and fosters a connection to the landscape thereby making us better placed to respond to future changes. Despite these benefits, current planning models such as new urbanism and transit-oriented design tend to give sense of place a low priority and as a result it can get lost. Given these issues, the focus of this research is “can landscape driven sense of place drive subdivision design without compromising on other urban planning criteria to produce subdivisions that address the issues of sprawl, as well as achieving the benefits associated with a strong sense of place that can improve our overall quality of life?” Answering this question required a thorough review of current urban planning and sense of place literature. This was used to critique existing subdivisions to gain a thorough understanding of the issues. The outcomes of this led to extensive design exploration which showed that, not only is it possible to design a subdivision with sense of place as the key driver but by doing this, the other urban planning criteria become easier to achieve.

Millions of urban residents around the world in the coming century will experience severe landscape change – including increased frequencies of flooding due to intensifying storm events and impacts from sea level rise. For cities, collisions of environmental change with mismatched cultural systems present a major threat to infrastructure systems that support urban living. Landscape architects who address these issues express a need to realign infrastructure with underlying natural systems, criticizing the lack of social and environmental considerations in engineering works. Our ability to manage both society and the landscapes we live in to better adapt to unpredictable events and landscape changes is essential if we are to sustain the health and safety of our families, neighbourhoods, and wider community networks. When extreme events like earthquakes or flooding occur in developed areas, the feasibility of returning the land to pre-disturbance use can be questioned. In Christchurch for example, a large expanse of land (630 hectares) within the city was severely damaged by the earthquakes and judged too impractical to repair in the short term. The central government now owns the land and is currently in the process of demolishing the mostly residential houses that formed the predominant land use. Furthermore, cascading impacts from the earthquakes have resulted in a general land subsidence of .5m over much of eastern Christchurch, causing disruptive and damaging flooding. Yet, although disasters can cause severe social and environmental distress, they also hold great potential as a catalyst to increasing adaption. But how might landscape architecture be better positioned to respond to the potential for transformation after disaster? This research asks two core questions: what roles can the discipline of landscape architecture play in improving the resilience of communities so they become more able to adapt to change? And what imaginative concepts could be designed for alternative forms of residential development that better empower residents to understand and adapt the infrastructure that supports them? Through design-directed inquiry, the research found landscape architecture theory to be well positioned to contribute to goals of social-ecological systems resilience. The discipline of landscape architecture could become influential in resilience-oriented multi disciplinary collaborations, with our particular strengths lying in six key areas: the integration of ecological and social processes, improving social capital, engaging with temporality, design-led innovation potential, increasing diversity and our ability to work across multiple scales. Furthermore, several innovative ideas were developed, through a site-based design exploration located within the residential red zone, that attempt to challenge conventional modes of urban living – concepts such as time-based land use, understanding roads as urban waterways, and landscape design and management strategies that increase community participation and awareness of the temporality in landscapes.

To the casual observer, community gardens may look like places where people just come to grow fruit and vegetables. Through digging beneath surface appearances, however, the research literature suggests that there is more to the creation of and participation in community gardens than that which is immediately apparent. The overall aim of this research was to explore and interpret the meaning of community gardens in terms of the sought and experienced well-being of the individuals who participate, and their associated communities. This research was undertaken in the Christchurch/Selwyn district, in the aftermath of the Christchurch earthquakes of 2010-2011. This research utilised the technique of photo-elicitation interviews to study the meanings attributed to community gardening, in the post-earthquake environment. Five gardens were investigated. Results show that a range of meanings, and well-being outcomes are experienced through a combination of physical, educational, aesthetic appreciation, contemplative, creative and social connections within the garden and within the overall context of nature. Significantly, within the post-earthquake environment, the community gardens can offer participants the opportunity to appreciate life and what it means for them.

As far as suburbs with bad reputations go, Aranui in Christchurch often seems to dominate local public perceptions. High crime, high unemployment, low incomes, run-down state houses and uncared-for neighbourhoods have been the key words and phrases used over many decades. This reputation achieved national standing over the same period and in 2001 Aranui gained the dubious distinction of becoming the pilot project for the Labour Government’s state housing Community Renewal Programme initiated in 2001. It is common to read “Don’t buy or rent here” comments on websites and blogs advising prospective immigrants on where to live. One of the dispiriting moments in Aranui’s history came in September 2009 with the discovery of two bodies under the floorboards of a Hampshire Street property and the subsequent charge of double-homicide and conviction of local resident Jason Somerville for the murder of his wife Rebecca Chamberlain and neighbour Tisha Lowry.

This thesis is a theoretical exploration of ‘remembrance’ and its production in the interactions between people/s and the landscape. This exploration takes place in the broad context of post earthquake Christchurch with a focus on public spaces along the Ōtākaro – Avon river corridor. Memory is universal to human beings, yet memories are subjective and culturally organized and produced - the relationship between memory and place therefore operates at individual and collective levels. Design responses that facilitate opportunities to create new memories, and also acknowledge the remembered past of human – landscape relationships are critical for social cohesion and wellbeing. I draw on insights from a range of theoretical sources, including critical interpretive methodologies, to validate subjective individual and group responses to memory and place. Such approaches also allowed me, as the researcher, considerable freedom to apply memory theory through film to illustrate ways we can re-member ourselves to our landscapes. The Ōtākaro-Avon river provided the site through and in which film strategies for remembrance are explored. Foregrounding differences in Māori and settler cultural orientations to memory and landscape, has highlighted the need for landscape design to consider remembrance - those cognitive and unseen dimensions that intertwine people and place. I argue it is our task to make space for such diverse relationships, and to ensure these stories and memories, embodied in landscape can be read through generations. I do not prescribe methods or strategies; rather I have sought to encourage thinking and debate and to suggest approaches through which the possibilities for remembrance may be enhanced.

Akaroa is a small township situated within Akaroa Harbour, on the southern side of Banks Peninsula. It is approximately 75 kilometres, or 90 minutes by car, from Christchurch City. At the 2006 Census of Population and Dwellings, the ‘usually resident’ population of the township was 510 people. In addition to the usually resident population, Akaroa has a large number of non-resident property owners/ratepayers, many of whom own holiday homes. Many of these holiday homes are available as casual rentals (i.e., they may be occupied by people other than the property owners). The township acts as a service centre for the scattered population of the outer bays area of Akaroa Harbour, many of whom work in Akaroa. Akaroa is a popular day trip or short stay destination for Christchurch residents. Akaroa is also known as a destination which draws upon the French heritage of its pioneer settlers and the associated village charm derived from this heritage. Not unexpectedly, given the size and village character of Akaroa, the increase in cruise ship arrivals and passenger numbers has had an impact upon the town’s community.This research was commissioned and funded by Christchurch and Canterbury Tourism (CCT).

This article reports on a study of community attitudes to cruise tourism in Akaroa, New Zealand. An important dimension of this study is the significant rate of growth in cruise arrivals over a short period of time as the result of the 2010/11 Canterbury earthquakes. Data were collected via a postal survey of the Akaroa community, and yielded a response rate of 56.6% (n = 316). The results indicate that despite the recent growth in arrivals, the Akaroa community holds a largely favorable opinion of cruise tourism. Importantly, the impacts identified by respondents were more closely aligned to threats to their identity as a destination, rather than problems with tourism, per se.
