The need for an integrated approach to disaster risk reduction (DRR) is widely promoted across the contemporary disaster literature and policy discourse. In Australia, the importance of integrating bushfire management and land use planning systems is a growing priority as bushfire risk in urbanized areas increases. This paper examines the changing policy landscape towards an integrated DRR regime for land use planning and bushfire management in south-west Western Australia. The research is based on a qualitative analysis of policy documents and in-depth interviews with policy actors associated with this regime. The results identify several challenges of policy integration for an integrated land use planning and bushfire management DRR regime, including incompatible worldviews, sectorial objectives and knowledge sets. A lack of cross-sectoral understanding, different risk tolerances and instrument preferences also constrained integration efforts. Based on our findings, we argue that rule-based mechanisms, which establish a legal framework for integration, are necessary when different policy goals and worldviews prevail between policy sectors. However, we conclude by emphasizing the value of actor-based mechanisms for integrated DRR policy regimes, which enable ongoing cross-sectoral communication and policy learning and facilitate a systems-oriented perspective of disaster resilience in the built environment.

Mega-bushfires like the 2009 Black Saturday, Australia, the 2016 Fort McMurray fire, Canada, and the 2018 Carr fire, USA cause billions of dollars in damage and result in loss of life. The sources of ignition of the fires are often natural or accidental such as lightning, campfire, cigarette butts, or machinery and tools (Miller, Plucinski et al. 2017). The frequency of bushfires isset to increase due to the positive feedback effect of climate change (Jolly, Cochrane et al. 2015). There is an increasing trend of settlement of people at wildland-urban-interface (WUI) (Radeloff, Helmers et al. 2018) which increases the impact of bushfire. Accurate and quick prediction of the evacuation of communities and the behaviour of a bushfire will make a difference in reducing the impact of bushfire (Mell, McDermott et al. 2010, Ronchi, Gwynne et al. 2017).

The scale and intensity of bushfire activity in Australia is likely to increase as a result of climate change. Effective bushfire management policy measures are therefore essential to minimise the interrelated social, environmental and economic impacts of fire in the landscape. This paper presents a historical review of bushfire management in the South West of Australia (SW): a bushfire prone and biodiverse region. Using a worldview framework to analyse key policy documents and literature, the paper demonstrates that the evolution of complex policy sectors such as bushfire management, is influenced not only by scientific and technical developments but also as a result of changing worldviews. Adapting the Integrative Worldview Framework (IWF), seven worldview categories that dominated particular periods of history in Australia are presented. These worldview categories are then used to examine the evolution of bushfire management practice, policy and institutional arrangements relevant to the SW. The argument presented herein is that a better understanding of worldviews and how they influence complex and contentious policy fields such as bushfire management, is useful for policy analysis, reflexive practice and research. The paper suggests an integrative worldview approach, which enables opportunities for exchanges and constructive conflict between stakeholders and agencies with diverse worldviews, could contribute to creating more sustainable bushfire management. Finally, it is argued that opportunities for Indigenous and Western worldview exchanges in the bushfire management sector, through collaborative knowledge partnerships could assist the sector in both management practice and policy formulation.

The propagation of bushfire across the landscape is dependent on a variety of environmental factors, but the wind, in particular, has a major effect on both the speed and direction of fire propagation. As such, bushfire spread models, which underpin successful bushfire management, require accurate knowledge of the pattern of winds across the landscape. This can be problematic over complex terrain where winds exhibit considerable spatial variability due to wind-terrain interactions, and where detailed measurements of wind characteristics are comparatively rare.

This thesis contributes two new wind datasets to address the previous lack of data available to develop and validate wind models over complex terrain. It also details analyses that focus on the statistical characterisation of wind as joint wind direction distributions, which represent the directional wind response to changing topography and surface roughness. A novel method for toroidal surface fitting is introduced and implemented to estimate the true continuous response from discrete observed data. This new method, which relies on a conceptually simple adaptation of planar techniques, is compared to the limited range of available toroidal surface estimation techniques and is shown to perform as well as, if not better than, these more sophisticated methods.

Monte Carlo simulations are employed to highlight the sensitivity of statistical comparison tests to alternative distribution structures, and to validate bivariate and circular extensions of the Kolmogorov-Smirnov test. These tests are applied to directional wind response pairs, showing that vegetation regrowth has a significant but varying impact across complex terrain.

Finally, this thesis demonstrates how statistical approaches can be used to complement current physics-based wind modelling methods. The resulting probabilistic representations provide more accurate predictions of wind direction variability, and are better suited to emerging ensemble-based bushfire prediction frameworks. As such, they provide a superior characterisation of uncertainty across the fire modelling process; ultimately enabling fire managers to make more informed decisions.
