Title: Effective Communication of Model Uncertainty
“Different mathematical and computational models have been designed by scientist/modeler with an aim to support decision-making during emergency response and recovery. However, in these modelling process, uncertainties are manifested starting from input data, during model run, and during generating output. Communication of these model uncertainties are believed helpful during decision-making. However, we lack knowledge on decision makers need on model uncertainties. So, through this research, decision-makers need will be identified, while also interacting with scientist around current practice. Through gaining rich, insightful, and nuanced understandings of decision-making needs, and current uncertainty communication practice by the scientist, the study will help develop a guiding mechanism to communicate model uncertainty.”

Title: Socio-economic Adaptation to Ongoing Taranaki Volcanism
“My research focuses on enhancing socio-economic adaptation and resilience to potential long-term volcanic disruption caused by Mt. Taranaki. My holistic perspective highlights complex interactions between system components, while the application of System Dynamics methodology enables the simulation of plausible changes in the behaviour of aspects of the socio-economic system under distress. My research seeks to identify robust strategies and pathways for dynamic transition through long-term disruption under conditions of deep uncertainty. This transdisciplinary topic sits at the interface of hazard management, socio-economics, decision theory, and systems science.”

Title: Assessing Dynamic Value Chains under Cascading Natural Hazards
“New Zealand is exposed to a wide range of natural hazards and with the growing influence of climate change, New Zealand’s exposure and vulnerability to natural hazards is likely to increase. Many of the impacts of these disruptions will be economic in nature and can be estimated. However, traditional approaches often overlook the unique disruptive elements of natural hazards such as the out of equilibrium dynamics and the propagation of impacts along the economy’s value chains. Using an approach that intertwines ecology and economics, my research will incorporate standard (input-output) and emerging (network analysis) economic practices with business transaction data to estimate the dynamic spatial and temporal impacts of disruptions to address the limitations of standard economic approaches. Improved estimation of natural hazard disruptions will provide improved clarity in local (business, industry, or regional level) and national decision-making processes to provide better recommendations of disaster risk reduction strategies. This approach will be applied to a case study focused on the Rangitaiki and Tarawera river systems in New Zealand’s Bay of Plenty region.”

Title: The Application of Integrated Land Use and Economic Models to the Simulation of Natural Hazard Events
“To date, most applications of economic and land use change models to the assessment of natural hazards have focused on assessing vulnerability, capital, fatality, and short-run economic impacts. This research applies the integration of a land use change and an economic model to a hypothetical volcanic eruption to demonstrate the simulation of long term-long land use change and economic impacts and recovery pathways after a natural hazard event has occurred. The research also develops a concept called Built Environment Services that enables bringing more holistic measures of well-being and important characteristics of the built environment into integrated modelling.”

Title: Modelling the Economic Implications of Coastal Managed Retreat
“My thesis presents a new method to support robust approaches to implementing coastal managed retreat for coastal communities exposed to climate change through rising sea levels and increasing storminess. It uses Evolutionary Economic analysis, System Dynamics, Scenario Planning and Robust Decision Making to identify Dynamic Adaptative Policy Pathways for implementation. The approach models scenarios of baseline climate risk, coastal mitigation and adaptation to assess the economic implications of a large-scale managed retreat for a study area in Hawke’s Bay, well known for exposure to a range of coastal hazards. It develops a new integrated assessment model called C-ADAPT to assess possible pathways for vulnerable communities to adapt to coastal hazards until 2050. The economic impact modelling utilises the quasi-computational general equilibrium model ‘MERIT’ developed by Market Economics and GNS.”

Title: Tackling Complexity using Interlinked Thinking: Well-being as a Case Study
“The world today is made up of a series of highly interconnected complex systems characterised by uncertainty. Human minds struggle with complexity, and the tools available to help us are limited. This often leads to reductionism, focusing on the parts rather than the whole. Working with individual parts ignores the dynamics that result from interdependencies between components. It is these interactions that determine the behaviour we experience in real world situations. This PhD presents ‘interlinked thinking’ as a communication and analytical approach to help people work with, rather than ignore, complexity. It is a participatory process that allows people not familiar with systems thinking to have a structured dialogue on how components interrelate.”
