In the aftermath of the 2010-2011 Canterbury Earthquake Sequence (CES), the location of Christchurch-City on the coast of the Canterbury Region (New Zealand) has proven crucial in determining the types of- and chains of hazards that impact the city. Very rapidly, the land subsidence of up to 1 m (vertical), and the modifications of city’s waterways – bank sliding, longitudinal profile change, sedimentation and erosion, engineered stop-banks… - turned rainfall and high-tides into unprecedented floods, which spread across the eastern side of the city. Within this context, this contribution presents two modeling results of potential floods: (1) results of flood models and (2) the effects of further subsidence-linked flooding – indeed if another similar earthquake was to strike the city, what could be the scenarios of further subsidence and then flooding. The present research uses the pre- and post-CES LiDAR datasets, which have been used as the boundary layer for the modeling. On top of simple bathtub model of inundation, the river flood model was conducted using the 2-D hydrodynamic code NAYS-2D developed at the University of Hokkaido (Japan), using a depth-averaged resolution of the hydrodynamic equations. The results have shown that the area the most at risk of flooding are the recent Holocene sedimentary deposits, and especially the swamplands near the sea and in the proximity of waterways. As the CES drove horizontal and vertical displacement of the land-surface, the surface hydrology of the city has been deeply modified, increasing flood risks. However, it seems that scientists and managers haven’t fully learned from the CES, and no research has been looking at the potential future subsidence in further worsening subsidence-related floods. Consequently, the term “coastal quake”, coined by D. Hart is highly topical, and most especially because most of our modern cities and mega-cities are built on estuarine Holocene sediments.
Prior to the devastating 2010 and 2011 earthquakes in Christchurch, New Zealand, the University of Canterbury (UC) was renowned for its graduates’ academic preparation and its staff’s research outputs. The town/gown relationship was aloof and strained due to UC’s move from the CBD in the 1970s and students being seen as troublemakers. Despite its vision of people prepared to make a difference, the University’s students and staff were not seen as making a difference in the local community or as being engaged citizens. This changed when over 9,000 UC students mobilized themselves into the Student Volunteer Army to provide immediate relief across Christchurch following the four major quakes of 2010 and 2011. Suddenly, UC students were seen as saviors, not miscreants and a focus on citizenship education as part of the University’s strategic direction began to take shape. Based on qualitative and quantitative research conducted at UC over the past four years, this interactive presentation will highlight the findings, conclusions, and implications of how the University has been transformed into a recognized, international leader in citizenship education. By integrating students’ community service into their academic studies, the University has changed its persona while students have gained academically, civically, and personally.

The New Zealand city of Christchurch suffered a series of devastating earthquakes in 2010-11 that changed the urban landscape forever. A new rebuilt city is now underway, largely based on the expressed wishes of the populace to see Christchurch return to being a more people-oriented, cycle-friendly city that it was known for in decades past. Currently 7% of commuters cycle to work, supported by a 200km network of mostly conventional on-road painted cycle lanes and off-road shared paths. The new "Major Cycleways" plan aims to develop approximately 100km of high-quality cycling routes throughout the city in 5-7 years. The target audience is an unaccompanied 10-year-old cycling, which requires more separated cycleways and low-volume/speed "neighbourhood greenways" to meet this standard. This presentation summarises the steps undertaken to date to start delivering this network. Various pieces of research have helped to identify the types of infrastructure preferred by those currently not regularly cycling, as well as helping to assess the merits of different route choices. Conceptual cycleway guidelines have now been translated into detailed design principles for the different types of infrastructure being planned. While much of this work is based on successful designs from overseas, including professional advice from Dutch practitioners, an interesting challenge has been to adapt these designs as required to suit local road environments and road user expectations. The first parts of the new network are being rolled out now, with the hope that this will produce an attractive and resilient network for the future population that leads to cycling being a major part of the local way of life.

New Zealand is one of the most highly urbanised countries in the world with well over 87 per cent of us living in 138 recognised urban centres, yet the number of people residing in inner city areas is proportionally very low. Householders have been exercising their preference for suburban or rural areas by opting for low density suburban environments. It is widely agreed that productivity and sustainability increase when people aggregate in the inner city, however there is a perceived trade-off between the density and liveability of an area. Achieving liveability in the inner city is concerned with reducing the pressures which emerge from higher population densities. Promoting inclusive societies, revitalising underutilised cityscapes, ensuring accessibility and fostering sense of place, are all elements essential to achieving liveable communities. The rebuild following the 2010 and 2011 Canterbury earthquakes provides Christchurch with an opportunity to shape a more environmentally sustainable, economically vibrant and liveable city. This research involves undertaking a case study of current inner city liveability measures and those provided for through the rebuild. A cross-case analysis with two of the world’s most liveable cities, Melbourne and Vancouver, exposes Christchurch’s potential shortcomings and reveals practical measures the city could implement in order to promote liveability.

While there are varying definitions of the term ‘social cohesion’, a number of common themes regularly surface to describe what cohesive societies look like. Previous studies using known indicators of social cohesion have often been conducted at the international level for cross-country comparison, while there has been less focus on social cohesion within countries. The purpose of this research is to identify if indicators of social cohesion can be used to map trends at the city level in order to draw meaningful conclusions, particularly in the aftermath of a natural disaster. Using known indicators of social cohesion and Christchurch City as the basis for this study, variations in social cohesion have been found within the city wards, that preceded but were affected by the events of the Canterbury earthquakes during 2010/11. These findings have significant policy implications for the future of Christchurch, as city leaders work towards the recovery of and subsequent rebuilding of communities.
