The lived reality of the 2010-2011 Canterbury earthquakes and its implications for the Waimakariri District, a small but rapidly growing district (third tier of government in New Zealand) north of Christchurch, can illustrate how community well-being, community resilience, and community capitals interrelate in practice generating paradoxical results out of what can otherwise be conceived as a textbook ‘best practice’ case of earthquake recovery. The Waimakariri District Council’s integrated community based recovery framework designed and implemented post-earthquakes in the District was built upon strong political, social, and moral capital elements such as: inter-institutional integration and communication, participation, local knowledge, and social justice. This approach enabled very positive community outputs such as artistic community interventions of the urban environment and communal food forests amongst others. Yet, interests responding to broader economic and political processes (continuous central government interventions, insurance and reinsurance processes, changing socio-cultural patterns) produced a significant loss of community capitals (E.g.: social fragmentation, participation exhaustion, economic leakage, etc.) which simultaneously, despite local Council and community efforts, hindered community well-being in the long term. The story of the Waimakariri District helps understand how resilience governance operates in practice where multi-scalar, non-linear, paradoxical, dynamic, and uncertain outcomes appear to be the norm that underpins the construction of equitable, transformative, and sustainable pathways towards the future.

In this paper we apply Full waveform tomography (FWT) based on the Adjoint-Wavefield (AW) method to iteratively invert a 3-D geophysical velocity model for the Canterbury region (Lee, 2017) from a simple initial model. The seismic wavefields was generated using numerical solution of the 3-D elastodynamic/ visco- elastodynamic equations (EMOD3D was adopted (Graves, 1996)), and through the AW method, gradients of model parameters (compression and shear wave velocity) were computed by implementing the cross-adjoint of forward and backward wavefields. The reversed-in-time displacement residual was utilized as the adjoint source. For inversion, we also account for the near source/ station effects, gradient precondition, smoothening (Gaussian filter in spatial domain) and optimal step length. Simulation-to-observation misfit measurements based on 191 sources at 78 seismic stations in the Canterbury region (Figure 1) were used into our inversion. The inversion process includes multiple frequency bands, starting from 0-0.05Hz, and advancing to higher frequency bands (0-0.1Hz and 0-0.2Hz). Each frequency band was used for up to 10 iterations or no optimal step length found. After 3 FWT inversion runs, the simulated seismograms computed using our final model show a good matching with the observed seismograms at frequencies from 0 - 0.2 Hz and the normalized least-squared misfit error has been significantly reduced. Over all, the synthetic study of FWT shows a good application to improve the crustal velocity models from the existed geological models and the seismic data of the different earthquake events happened in the Canterbury region.

Natural hazards continue to have adverse effects on communities and households worldwide, accelerating research on proactively identifying and enhancing characteristics associated with resilience. Although resilience is often characterized as a return to normal, recent studies of postdisaster recovery have highlighted the ways in which new opportunities can emerge following disruption, challenging the status quo. Conversely, recovery and reconstruction may serve to reinforce preexisting social, institutional, and development pathways. Our understanding of these dynamics is limited however by the small number of practice examples, particularly for rural communities in developed nations. This study uses a social–ecological inventory to document the drivers, pathways, and mechanisms of resilience following a large-magnitude earthquake in Kaikōura, a coastal community in Aotearoa New Zealand. As part of the planning and implementation phase of a multiyear project, we used the tool as the basis for indepth and contextually sensitive analysis of rural resilience. Moreover, the deliberate application of social–ecological inventory was the first step in the research team reengaging with the community following the event. The inventory process provided an opportunity for research partners to share their stories and experiences and develop a shared understanding of changes that had taken place in the community. Results provide empirical insight into reactions to disruptive change associated with disasters. The inventory also informed the design of targeted research collaborations, established a platform for longer-term community engagement, and provides a baseline for assessing longitudinal changes in key resilience-related characteristics and community capacities. Findings suggest the utility of social–ecological inventory goes beyond natural resource management, and that it may be appropriate in a range of contexts where institutional, social, and economic restructuring have developed out of necessity in response to felt or anticipated external stressors.

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.
