Earthquakes rupture not only the objective realm of the physical landscape, but also the subjective landscape of emotions. Using the concepts of topophilia and topophobia developed by Yi-Fu Tuan as theories of love and fear of place, this paper investigates the impact of
Christchurch’s earthquakes of 2010 and 2011 on relationships with the city’s landscape.
Published accounts of the earthquakes in newspapers from around New Zealand are examined for evidence of how people responded to the situation, in particular their shifting relationship with familiar landscapes. The reports illustrate how residents and visitors reacted to the actual
and perceived changes to their surroundings, grappling with how a familiar place had become alien and often startling. The extreme nature of the event and the death toll of 185 heightened perceptions of the landscape, and even the most taken-for-granted elements of the landscape became amplified in significance. Enhanced understanding of the landscape of emotions is a vital component of wellbeing. Through recognising that the impact of disasters and perceived threats to familiar places has a profound emotional effect, the significance of sense of place to wellbeing can be appreciated.
A series of earthquakes has forced Christchurch to re-plan and rebuild. Discussions about rebuilding strategies have emphasized the intention of making it a city for the future, sustainable and vibrant. This paper discusses the relationship between microclimate and urban culture in Christchurch based upon the concept of urban comfort. It explores the relationships between environment, people and culture to help understand the local requirements for urban landscape design. In this paper we claim
that cultural requirements also should be taken into account when looking for sustainable strategies. A distinctive feature of this research is its focus on the way people are adapting to both surviving prequake and new post‐quake environments. Preliminary findings from the first year of field work using participant observation and 61 in‐depth interviews with Christchurch residents are presented. The interviews were carried out in a variety of
urban settings including: established sites (places sustaining relatively little damage) and emerging
sites (those requiring rebuilding) during 2011‐2012. Evidence from the interviews highlight future challenges regarding sustainability and urban comfort issues. Post‐quake Christchurch presents a remarkable opportunity to design an urban landscape which provides environmental, economic, social and cultural sustainability. However, to achieve successful outcomes it is fundamental to respond to the local culture. Field data suggest that the strong connections between urban and rural settings present in local culture, lifestyle and landscape generate a particular aesthetic and recreation preference for urban spaces, which should be considered in the urban landscape design strategies.
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.
This report focuses on the Waimakariri District Council's approach to earthquake recovery which was developed as an Integrated, Community-based Recovery Framework. This approach has been held up as exemplary in a number of fora and has received a great deal of interest and support both nationally and internationally. It has evolved as a result of the September earthquake and the thousands of aftershocks that have followed, along with the regulatory changes that have impacted on building safety and land availability since, but it builds on a set of pre-existing competencies and a well-established organisational culture that focusses on:
* Working with communities and each other;
* Keeping people informed;
* Doing better everyday;
* Taking responsibility;
* Acting with integrity, honesty and trust.
The report identifies, and speaks to, three themes or tensions drawn from either the disaster/emergency management literature or actual cases of recovery practice observed here in Canterbury over the last 2 years. These themes are the:
1. unique position of local government to undertake integrated or ‘holistic’ recovery work with community at the centre, versus the lack of clarity around both community and local government’s role in disaster recovery; 2. general consensus that good local government-community relationships are crucial to recovery processes, versus the lack of practical advice on how best to engage, and engage with, communities post-disaster; and 3. balancing Business as Usual (BaU) with recovery issues.Ministry of Civil Defence and Emergency Management.
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.
