Cognitive and Affective Processes Underlying Risk COGNITIVE AND AFFECTIVE PROCESSES UNDERLYING RISK PERCEPTIONS AND INTENTIONS OF FLOOD-PRONE HOUSEHOLDS (A dual-process approach) BY LARA ALTARAWNEH BSc(Hons) Architecture A thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy in ARCHITECTURE, From the School of Architecture and Built Environment at the University of Newcastle, Australia OCTOBER 2018 Supervised by Associate professor Jamie Mackee Associate professor Thayaparan Gajendran This research was supported by the University of Newcastle International Postgraduate Research Scholarship (UNIPRS) I hereby certify that the work embodied in the thesis is my own work, conducted under normal supervision. The thesis contains no material which has been accepted, or is being examined, for the award of any other degree or diploma in any university or other tertiary institution and, to the best of my knowledge and belief, contains no material previously published or written by another person, except where due reference has been made in the text. I give consent to the final version of my thesis being made available worldwide when deposited in the University’s Digital Repository, subject to the provisions of the Copyright Act 1968 and any approved embargo. SIGNATURE DATE OCTOBER 2018 ii ABSTRACT From a socio-psychological perspective, this thesis has sought to unearth the core factors influencing householders’ response to flood risk in a bid to identify how a shift towards greater protection levels can be harnessed. In doing so, a framework was developed for understanding household decision making in flood-prone areas of South East Queensland, Australia. This framework illustrates the pathways by which household decision making is influenced by dual processes (affective and cognitive) operating at different levels of influence: 1. conjointly (and directly) shaping flood preparedness intentions; 2. mediating the (indirect) influence of other core factors (personal experience, subjective knowledge, self-efficacy and trust) on flood preparedness intentions; and, 3. being moderated by the influence of benefit perception (operationalized as “residential satisfaction”) on flood preparedness intentions. Additionally, the framework stresses the relevance of understating the role and the predictors of householders’ non-protective response (i.e. risk denial). In this vein, a shift from non-protective to protective behavioural intentions can be best realized. iii ACKNOWLEDGMENTS Undertaking this PhD has been a truly life-changing experience for me and it would not have been possible without the help that I received from many people. First, and foremost, I would like to express my sincere gratitude to my supervisors Assoc. Prof. Jamie MacKee and Assoc. Prof. Thayaparan Gajendran for their patient guidance, enthusiastic encouragement and useful critiques. I would like to acknowledge the input and feedback provided by Micromex Research and Consulting while conducting the field work, including survey implementation and overall data collection. A special word of gratitude to Ms. Fran Baker for helping me with statistical analysis pertaining to my research work and for her expert guidance and invaluable suggestions rendered during the study. I would like to give special thanks to the members of my thesis review committee (Assoc. Profe. Raufdeen Raieezdeen and Prof. Bingunath Ingirige), who gave detailed insightful comments about my research work. The comments have helped me greatly in preparing this final version of my thesis. On the same note, I would like to thank the members of my oral examination (PhD Confirmation) committee for raising a number of interesting points of discussion and possible future research directions. I want to especially mention Dr. Jason von Meding and Dr. Helen Giggins in this regard. I extend my sincere gratitude to the University of Newcastle, who provided a four year scholarship, which covered both tuition fees and living allowance. I am also very grateful to the administrative and technical staff members of the School of Architecture and Built Environment who have been kind enough to advise and help in their respective roles. I would also like to acknowledge the intellectual environment provided by my past and present colleagues. Just a few to name: Shanying Shih, Giuseppe Forino, Tohid Fardpour, Owi Toinpre, Matthew Abunyewah and Reza Forghani.

I would also like to thank my friends (Ammar Homsi, Florens Pattiasina, Farshid Evazabadi, Andrei Pomana, Juan Quijano, Sylvia Chan, David Chan, Ashraf Alqadi, Mohammad Alayyat and Sahar Rabadi), who provided a much needed form of escape from my studies, also deserve thanks for helping me keep things in perspective. Finally, and certainly not least, this research would not have been possible without those people who gave up their time to participate in the research. Residents in the two locations (Ipswich and Gold Coast) generously provide me with their quantitative data and shared their often difficult experiences of what it is like be flooded. I humbly present my wholehearted thanks to all of them.

  • Storm Surge: Know Your Risk in Queensland!
    Storm Surge: Know your risk in Queensland! Storm surge is a rise in sea level above the normal tide usually associated with a low pressure weather system such as a tropical cyclone. Storm surge develops due to strong winds pushing water towards the coastline as well as the low atmospheric pressure drawing up the sea surface. The Queensland coastline is highly vulnerable to storm surge. This is due to the frequency of tropical cyclones, the wide continental shelf and relatively shallow ocean floor in both the Great Barrier Reef lagoon and in the Gulf of Carpentaria, as well as the low lying nature of many coastal cities and towns. While the highest storm surges are more likely to occur in North Queensland and the Gulf of Carpentaria, they can also develop in southeast Queensland affecting the Sunshine Coast, Moreton Bay and the Gold Coast. Storm surges may reach magnitudes of 1 to 10 metres above the tide depending on the intensity of the cyclone, its size and the local characteristics of the coastline. Impacts Coral Sea Storm surge can be very dangerous and poses a critical risk Gulf of Carpentaria to human life during tropical cyclones. Great Cairns Barrier Reef The length of coastline affected by a storm surge can be Innisfail tens to hundreds of kilometres wide.

Authorising law Sections 10, 11 and 44 of the Rural and Regional Adjustment Act 1994 (the Act) Policy objectives and the reasons for them Financial assistance to those who have been directly impacted by eligible disasters is governed by the joint Commonwealth-State Natural Disaster Relief and Recovery Arrangements (NDRRA). The NDRRA is a cost sharing arrangement between the states and the Commonwealth Government which establishes a suite of pre-approved measures which can potentially be activated in response to an eligible disaster in order to assist with community recovery. Eligible disasters include bushfire, earthquake, flood, storm, cyclone, storm surge, landslide, tsunami, meteorite strike, tornado or terrorist event. Rural and Regional Adjustment Amendment Regulation (No. 2) 2013 The NDRRA pre-approved measures are broken down into four categories namely: • Category A - assistance to individuals. • Category B - assistance to business (i.e. small business, not-for-profit organisations and primary producers) and government. • Category C - a community recovery package and clean-up and recovery grants for severe disasters where Category A and B measures are insufficient. • Category D - measures to be introduced on a case by case basis in response to exceptional events where Categories A, B and C are inadequate. Category B concessional loans to primary producers and small business are contained in Schedules 2 and 3 of the Rural and Regional Adjustment Regulation 2011 and Category C clean up and recovery grants are contained in Schedule 23.
