Measuring community resilience

AH Kwok
As New Zealand seeks to develop tools for assessing resilience as part of its national resilience strategy, this report illustrates how a direct translation of resilience indictors and indicator variables from the Benchmarking Resilience Indicators for Communities (BRIC) – a U.S.-based resilience assessment tool – for New Zealand presents both challenges and opportunities. Key challenges include the absence of publicly available datasets at different geographic scales and the applicability of indicator concepts that reflect New...

Sampling was undertaken at 83 sites across a 1 km grid, with a further 30 sites sampled within the grid from almost all primary, intermediate and secondary schools within the survey area. At each site, three samples were collected using a hand auger: an upper O-depth...

Liquefaction hazard in the Wellington Region

GD Dellow, ND Perrin & WF Ries
The greater Wellington Region has a higher annual probability of damaging ground shaking than most of the rest of New Zealand. This means that the region is exposed to all of the effects of strong earthquake shaking including fault rupture, ground movement, liquefaction and landslides. This report deals specifically with the liquefaction hazard in the greater Wellington Region. Liquefaction is a process that leads to a soil suddenly losing much of its strength, most commonly...

Using RiskScape to inform section 32 assessments under the Resource Management Act 1991

ES Grace, NA Horspool, J Williams, S-L Lin & R Paulik
Land use planning decisions in New Zealand, including those that aim to manage levels of risk from natural hazards, are regulated by the Resource Management Act 1991 (RMA). The RMA includes a requirement to quantify costs and benefits of proposed policy options. A project has been undertaken to determine whether RiskScape, a risk modelling tool, can offer a means of quantifying costs and benefits relating to risk management options in the manner required by section...
