Building codes regulate the design and materials of structures in the built environment, often in parallel with related processes such as land use planning. Building codes establish a standard of certainty that structures achieve pre-established levels of safety and health. In parallel, building codes are potentially able to contribute to natural hazard resilience, although ongoing improvements are needed to account for a variety of emerging challenges and insights from new research.

This summary outlines a generalised method to assess building codes, their application in New South Wales, and related mechanisms in terms of their contribution to natural hazard resilience, identifying areas for improvement and further research. It ensures that methods used and findings are reported in language and formats easily accessible by a wider audience of emergency management, land use planning and design practitioners.

This report provides an overview, including the north Australian bushfire and natural hazard ({\textquoteleft}BNH{\textquoteright}) context and the social background for the North Australian Bushfire and Natural Hazard Training project.

The project has proceeded slowly (five years) and has changed dramatically as a result of engaging in Participatory Action Research ({\textquoteleft}PAR{\textquoteright}). This approach to researching the training needs of residents of remote north Australian communities encouraged these residents to participate in the framing of the enquiry as well as the generation of answers and training materials.

Several desktop reviews were undertaken during the project. These examined the existing BNH training offerings as well as the opportunities that existed at the time for Indigenous community members to obtain leadership training. The reviews found that where training existed it largely omitted Indigenous perspectives, particularly in terms of strategic overviews and planning. For leadership training, it was found that where remote communities were able to access training for BNH it did not focus on leadership and that which focused on leadership did not include BNH management.

In response to the views of project participants and the reviews, the project developed a set of training units that, taken together, drew together the essential elements of Indigenous and non-Indigenous BNH training in a Vocational Education and Training ({\textquoteleft}VET{\textquoteright}) style program. The program does however modify the {\textquoteleft}standard{\textquoteright} VET approach through the provision of flexible temporal arrangements for training and assessing. This need was identified as the project recognized the requirement to train {\textquoteleft}on Country [1]{\textquoteright} and to use local knowledge-holders in the preparations for and delivery of the training.

Nine formal {\textquoteleft}engagements{\textquoteright} were held over the life of the project, including workshops and three training pilots. In each pilot, different components of the ten training units were presented and refined. A detailed and culturally appropriate evaluation was undertaken of each pilot and the feedback was incorporated into the next {\textquoteleft}round{\textquoteright} of pilot training.

10 training units have been developed by the project. Some of these are entirely new while others are adaptations of existing training, albeit adapted sufficient to warrant a new unit descriptor.

The 10 units have not yet been subject to National Accreditation, but are designed to map onto the Standards for VET Accredited Courses as set out by the Australian Skills Quality Authority. Each unit has been framed in terms of {\textquoteleft}Elements and Performance Criteria{\textquoteright}, {\textquoteleft}Evidence Guide{\textquoteright}, {\textquoteleft}Requiired Skills and Knowledge{\textquoteright} and a {\textquoteleft}Range Statement{\textquoteright}.


[1] The capitalised term {\textquoteleft}Country{\textquoteright} is used throughout to indicate the entity which extends well beyond the English term for {\textquoteleft}nation{\textquoteright} or {\textquoteleft}landscape{\textquoteright} or {\textquoteleft}rural{\textquoteright}. For the Indigenous people who participated in this project {\textquoteleft}Country{\textquoteright} refers an entity which transcends physical, moral, spiritual and metaphysical realms and of which they are an integral part. Country is at all times the ground on which one stands but also inside a person (cf. Holmes \& Janpajimpa 2013: 18). It is something one can be taken off, but can never be removed from within.

Government emergency management agencies use public communication to inform and educate around risks such as floods, fires, storms, and earthquakes with the aim to help communities understand how to prepare for these emergency events. This study of government communication relating to emergency management preparedness examines an Australian context to understand the types of messages preparing community members for natural hazards. Findings suggest that agencies employ a two-track approach combining warranting and engagement messages. Yet a deeper look at the messages suggests a {\textquotedblleft}paradox of the positive{\textquotedblright} that overemphasizes the capacity of local agencies to respond to crises and underemphasizes citizen shared responsibility. Implications for the paradox of the positive in other national contexts and public relations theory building are also discussed.

There is increasing recognition of the urgency to consider how disaster risk might change into the future, what impacts this is likely to have and, most importantly, what we can do to reduce this risk.\  There is also increased recognition that in order to achieve this, we need to adopt a holistic approach that takes into account community values, vulnerabilities and resilience, future changes in population and demographics, climate change, multiple hazards, cascading events, adaptation and a range of risk reduction strategies, such land use planning, community education, land management, structural measures and changes to building codes.

Over the last 5 years, this project has co-developed conceptual, modelling and decision support frameworks for tackling the above problems in conjunction with more than 40 end-user organisations in four states (South Australia, Western Australia, Tasmania and Victoria).\  The frameworks facilitate (i) the development of the capacity for strategic thinking and for tackling long-term disaster risk in an integrated fashion, (ii) the collaboration between different government departments and different levels of government (federal, state and local), (iii) the development of a shared understanding of risks and values between a range of stakeholders (e.g. different levels of government and the community), (iv) the quantification of how disaster risks and costs might change into the future under a range of integrated socio-economic and climate scenarios and (v) the development of the best adaptive mitigation strategies under these scenarios.

The above frameworks have resulted in the development of the decision support software UNHaRMED (Unified Natural Hazards Risk Mitigation Exploratory Decision support system), applications for which have been co-developed with end users for greater Adelaide, Perth and surrounds, Tasmania and greater and peri-urban Melbourne.\  They are now being deployed in a variety of manners to support understanding and decision making on disaster risk reduction along with continual improvements to the capability.

In the last financial year users have now been trained in all jurisdictions. This report summarises some of the enhanced software capabilities along with describe several utilisation activities designed to highlight the benefits of using an interactive risk assessment tool in participatory settings. This has included facilitating a mitigation exercises for South Australian State and Local Government agencies exploring mitigation activities for a changing coastal risk profile and assessing floodplain management approaches in the Gawler River.

Context

Urban planning systems have considerable potential to modify the impacts of natural hazards upon the built environment, humans and associated systems. With the increased frequency of natural hazards due to climate change and increased exposure to hazards due to population growth pressures, especially in the urban-rural interface, there are also increased consequences for human settlements and likely exacerbation of the challenges associated with natural hazard impact.

In this context, this project sought to understand the limits and potentials of integrated urban planning for natural hazard mitigation in Australia, and the ways in which key planning processes for risk-based decision-making in the built environment can be improved. By doing so, it identified many gaps in the ways we currently seek to integrate urban planning and natural hazard risk management.

The primary questions posed by this research project were:

PQ1 {\textendash} What are the limits and potentials of integrated urban planning for natural hazard mitigation in Australia?

PQ2 {\textendash} How can key planning processes for risk-based decision making in the built environment be improved at local and state level, including generalizable and adaptable model processes and codes with practical illustrative cases?

Method

The project comprised 3 sequential stages that resulted in the development of diagnostic tools to assess and improve the integration of urban planning and natural hazard mitigation in Australia.

The first stage{\textendash}Mapping Current Knowledge, Best Practice and Challenges{\textendash}established an analytical framework to assess integration based on current knowledge, best practice and challenges. Using desktop research and end-user workshops, core integration principles were identified.

In the second stage{\textendash}Assessing Australian Planning and Ways Forward{\textendash}the set of integration principles was refined through its application to past Australian inquiries into natural hazard events. An analytical framework for assessing integration was also developed and diagrammatically represented to illustrate and map critical variables for the integration of Urban Planning and Natural Hazard Mitigation.

The third stage{\textendash}Applying and Generating Knowledge in New Ways{\textendash}applied and generated knowledge by undertaking an assessment of urban planning and natural hazard mitigation in two Australian case studies. In consultation with end-users, this assessment targeted proposed land use planning reforms in South Australia and a historical case of edge development in Metropolitan Melbourne in Victoria. Findings from these case studies informed the development of critical frameworks for best practice comprising three sets of diagnostic tools.

Learnings and findings

Learnings were captured in a set of scalable and adaptable diagnostic tools that are part of critical frameworks for best practice in integrating urban planning and natural hazard mitigation in Australia. These diagnostic tools allow assessment of integration and risk management across urban planning and emergency management systems and processes. This set of tools is the final product for this research project and the utilisation output delivered to end-users. This output represents a comprehensive understanding of the potentials and limits of urban planning systems when it comes to disaster risk reduction. It allows for a range of new ways forward to fully utilise and integrate urban planning with natural hazard mitigation actions and outcomes. Broadly, these diagnostic tools suggest that a comprehensive assessment of integration of urban planning and natural hazard mitigation should include consideration of

Utilisation

This project is in its first three-year cycle, so it was not able to move into utilisation.\  However, the outcomes of the work provide an ability to understand, critique and improve urban planning{\textquoteright}s influence and impact on risk reduction to natural hazards, providing many new ways forward.

Therefore, there is great potential for the utilisation of the critical model developed in the research to assess and guide reform in processes of land use planning in existing and future settlements. In particular, modifying the processes of state and local government during planning decision-making is likely to yield significant impact. The development of illustrative critical and explanatory understandings of the importance and application of urban planning as a tool for disaster risk reduction is in and of itself a significant output that can be utilised.

Many of the project findings have been included in the AIDR Handbook {\textquotedblleft}Land Use Planning for Disaster Resilient Communities{\textquotedblright} (March \& Gonzalez-Mathiesen, 2020) and have informed submissions to the Royal Commission into National Natural Disaster Arrangements (Stanley et al., 2020)and to the Inquiry into the 2019-2020 Victorian Fire Season (Stanley et al., 2020,embargoed).

There are many potential areas for ongoing utilisation. These fall under the following broad categories:

In this report, we outline a decision-support framework for natural hazard management that combines the use of simulation and optimisation for exploring what risk reduction measures best achieve management priorities. This framework addressed several needs that practitioners have with regard to risk and adaptation assessment. First, it uses optimisation approaches to screen through and identify those management options that perform best across a number of decision criteria. This is important, as there are a very diverse range of management options which could be combined in an extremely large number of ways to make portfolios of management options and it is difficult to screen through all potential portfolios to shortlist a small number for further consideration. Second, it simulates the effectiveness of management options over long-term planning horizons. This is important, for management options may have long lead-in-times, and/or may have long lifetimes, are not easily/readily changed, and so need to be effective over a broad range of plausible future conditions, which likely include larger populations, increased economic development and climate change. Third, the framework emphasises holistic assessment, wherein the Integrated assessment modelling (IAM) simulates the effect of management options across a number of criteria, therefore allowing practitioners to explore the trade-offs between risk reduction with other community goals, including environmental, social and economic outcomes.


The value of this framework arises from the greater demands that are being placed on planners to effectively manage natural hazard risk, whether from politicians or from the public who have an increasingly reduced appetite for hazard losses. This creates a need for analytic frameworks for exploring how to best manage risk, and this framework addresses this gap.


Through application to a case study, this report shows how the framework is able to increase the effectiveness and efficiency by which IAM can be applied to natural hazard risk management. The role of the optimisation was seen not to be prescriptive, but to enable better exploration of risk management options. The framework was therefore able to provide rich information on the effectiveness of management portfolios by which better risk management plans could be formed.


The case study to which the framework was applied considered coastal flood risk within Greater Adelaide and explored the combinations of zonal exclusion areas along the coast which prevented further development. If unmitigated, coastal risk could increase by 10\% over the next three decades. However, results of the case study application showed that zonal exclusion policies could effectively reduce this growth of coastal risk, however this required excluding further development from 7000 Ha of land along the coast. Saying that, the growth in risk could be limited to 3\% (i.e. a reduction in growth by 60\%), through excluding coastal development from only 1500 Ha.

Urban planning offers a range of potential benefits to reduce or even avoid many of the risks associated with natural hazards.\  However, it is is not always fully utilised as a core mechanism to manage natural hazard risks, particularly those relating to human settlements.

This document sets out a critical framework to guide improved integration of land use planning and wider natural hazard risk reduction actions. It is intended to support emergency managers and urban and regional planning practitioners in the complex task of integrating land use planning and disaster risk reduction in different Australian jurisdictions. The critical framework has been designed to speak to current terminology, processes and arrangements already used by these audiences.

The diagnostioc tools are scalable and adapatable to various circumstances and needs. Hence, the diagnoses can be applied to particiular hazards, certain geographical places, parts of or the entire planning system, or specific challenges associated with disaster risk reductions.

Three interconnected elements comprise the diagnstic tools, based on developing and applying knowledge regarding:

  1. Natural Hazards, the sources of harm or situations with a potential to cause loss with their core transmission systems in the natural world.0F[1]
  2. Cross-Cutting Themes, core disaster risk reduction principles that apply to all urban planning, settlement and natural hazard circumstances.
  3. Diagnostic Focus Areas, risk reduction principles that relate to key categories of urban planning, communities and the range of other systems they interact with.

The diagnostic tool includes a sequenced approach to examine complex situations and to develop logical and evidence-based directions for improved urban planning. This also allows improved connections with wider Disaster Risk Reduction practices.\

This study analyses the circumstances of vehicle-related flood fatalities between 2001 and 2017, in Australia. The research identified 96 deaths from 74 incidents during this period. The aim of this analysis is to understand the demographic, spatial and temporal patterns, and the situational conditions in which those (n\ = 96) deaths have occurred. This is important for informing efficient and strategic risk reduction strategies to reduce vehicle related deaths and injuries in floodwater. Data were accessed from the Australian National Coronial Information System (NCIS), which includes witness and police statements, forensic documents, and detailed coronial findings. Analysis was conducted in two phases. In phase one, data were coded and categorised according to a range of factors previously identified as significant in vehicle-related flood fatalities internationally. In phase two, a detailed analysis was conducted on 11 selected incidents for which there were complete sets of records. This detailed analysis provides insight into the multifaceted nature of fatal vehicle-related flood fatality incidents. The overall results reveal that, for drivers, middle-aged and elderly males are over-represented in the fatality statistics. As passengers, young women and children are vulnerable. The study also identified deep floodwater with high flow contributes more to vehicle immersion, and the presence of alcohol and drugs, leading to impaired responses, reduces the chance of survival for the vehicle occupants.
