<p>‘Resilience’ is a term that is increasingly being used regarding community development issues. It is a particular issue on Pacific Islands where development issues exist, and the exposure of communities to natural hazards is apparent. Climate change is increasingly affecting Pacific Island communities. Many Pacific Island communities live on low-lying atolls, and communities on ‘high’ islands are generally located close to the coast. Both sets of communities are therefore highly exposed to storm and high seas events. Additionally, earthquake, tsunami and volcanic hazards exist. Infrastructure is a key aspect of resilience. Policies and technical issues regarding infrastructure resilience globally are the subject of a literature review. Research presented compares the policies taken to resilient infrastructure in (Western) Samoa against those taken in American Samoa. These two territories shared common cultural histories until the 19th century, both are ‘high’ islands and both face a similar range of natural hazards faced due to their relative close proximity in the Pacific Ocean. Analysis highlights where lessons can be learnt both globally and from the Samoas’ approaches to resilient infrastructure. The lessons learnt in this thesis include the value of taking a holistic approach to disaster risk reduction, involving the community in hazard identification and disaster risk reduction, and working on these issues in a timely manner. Additionally, it is seen that careful long-term planning of land use with natural hazards in mind, which is found to be an economically sound approach, is of value in disaster risk reduction.</p>

The Sendai Framework of Action 2015–2030 calls for holistic Indigenous disaster risk reduction (DRR) research. Responding to this call, we synergized a holistic philosophical framework (comprising ecological systems theory, symbolic interactionism, and intersectionality) and social constructionist grounded theory and ethnography within a critical Indigenous research paradigm as a methodology for exploring how diverse individual and contextual factors influence DRR in a remote Indigenous community called Galiwinku, in the Northern Territory of Australia. Working together, Indigenous and non-Indigenous researchers collected stories in local languages using conversations and yarning circles with 20 community members, as well as participant observations. The stories were interpreted and analysed using social constructivist grounded theory analysis techniques. The findings were dialogued with over 50 community members. The findings deeply resonated with the community members, validating the trustworthiness and relevance of the findings. The grounded theory that emerged identified two themes. First, local Indigenous knowledge and practices strengthen Indigenous people and reduce the risks posed by natural hazards. More specifically, deep reciprocal relationships with country and ecological knowledge, strong kinship relations, Elder’s wisdom and authority, women and men sharing power, and faith in a supreme power/God and Indigenous-led community organizations enable DRR. Second, colonizing practices weaken Indigenous people and increase the risks from natural hazards. Therefore, colonization, the imposition of Western culture, the government application of top-down approaches, infiltration in Indigenous governance systems, the use of fly-in/fly-out workers, scarcity of employment, restrictions on technical and higher education opportunities, and overcrowded housing that is culturally and climatically unsuitable undermine the DRR capability. Based on the findings, we propose a Community-Based DRR theory which proposes that facilitating sustainable Indigenous DRR in Australian Indigenous communities requires Indigenous and non-Indigenous partners to genuinely work together in two-directional and complementary ways.

&lt;p&gt;Global policy frameworks, such as the Sendai Framework for Disaster Risk Reduction 2015-2030, increasingly advocate for multi-hazard approaches across different spatial scales. However, management approaches on the ground are still informed by siloed approaches based on one single natural hazard (e.g. flood, earthquake, snowstorm). However, locations are rarely subjected to a single natural hazard but rather prone to more than one. These different hazards and their interactions (e.g. one natural hazard triggering or increasing the probability of one or more natural hazards), together with exposure and vulnerability, shape the disaster landscape of a given region and associated disaster impact. &amp;#160;Here, as part of the UK GCRF funded research grant &amp;#8220;Tomorrow&amp;#8217;s Cities&amp;#8221; we first map out the single natural hazardscape for Nairobi using evidence collected through peer-reviewed literature, grey literature, social media and newspapers. We find the following hazard groups and hazard types present in Nairobi: (i) geophysical (earthquakes, volcanic eruptions, landslides), (ii) hydrological (floods and droughts), (iii) shallow earth processes (regional subsidence, ground collapse, soil subsidence, ground heave), (iv) atmospheric hazards (storm, hail, lightning, extreme heat, extreme cold), (v) biophysical (urban fires), and vi) space hazards (geomatic storms, and impact events). The breadth of single natural hazards that can potentially impact Nairobi is much larger than normally considered by individual hazard managers that work in Nairobi. We then use a global hazard matrix to identify possible hazard interactions, focusing on the following interaction mechanisms: (i) hazard triggering secondary hazard, (ii) hazards amplifying the possibility of the secondary hazard occurring.&amp;#160; We identify 67 possible interactions, as well as some of the interaction cascade typologies that are typical for Nairobi (e.g. a storm triggers and increases the probability of a flood which in turn increases the probability of a flood). Our results indicate a breadth of natural hazards and their interactions in Nairobi, and emphasise a need for a multi-hazard approach to disaster risk reduction.&lt;/p&gt;

Abstract. Gravitational natural hazards such as snow avalanches, rockfalls, shallow landslides and volcanic activity represent a risk factor for mountain communities around the world. In particular where documentary records about these processes are rare, decisions on risk management and land-use planning have to be based on a variety of other sources including vegetation and tree-ring data and natural hazard process models. We used a combination of these methods in order to evaluate dynamics of snow avalanches and other natural hazards at Valle de las Trancas, in the Biobío Region in Chile. Along this valley, natural hazards threaten not only the local human population, but also the numerous tourists attracted by outdoor recreational activities. Given the regional scarcity of documentary records, tree-ring methods were applied in order to reconstruct the local history of snow avalanches and debris flow events, which are the more important weather-related processes at respective tracks. A recent version of the model Rapid Mass MovementS (RAMMS), that includes influences of forest structure, was used to calculate different avalanche parameters such as runout distances and maximum pressures, taking into consideration the presence/absence of forest along the tracks as well as different modelled return periods. Our results show that local Nothofagus broadleaved forests contribute to a reduction of avalanche runout distances as well as impact pressures on present infrastructure, thus constituting a valuable ecosystem disaster risk reduction measure that can substitute or complement other traditional measures such as sheds.

Abstract. Here we present an interdisciplinary approach to developing comprehensive, systematic and evidenced regional interaction frameworks to support multi-hazard approaches to disaster risk reduction. We apply this approach in Guatemala, developing regional interaction frameworks for national and sub-national (Southern Highlands) spatial extents. The regional interaction frameworks are constructed and populated using five evidence types: (i) publications and reports (internationally accessible) (93 peer-review and 76 grey literature sources); (ii) publications and reports (locally accessible civil protection bulletins) (267 bulletins from 11 June 2010 to 15 October 2010); (iii) field observations; (iv) stakeholder interviews (19 semi-structured interviews) (v) stakeholder workshop results (16 participants). These five evidence types were synthesised to determine an appropriate natural hazards classification scheme for Guatemala, with 6 natural hazard groups, 19 hazard types, and 37 hazard sub-types. For a national spatial extent in Guatemala, we proceed to construct and populate a regional interaction framework (matrix form), identifying 50 possible interactions between 19 hazard types. For a sub-national spatial extent (Southern Highlands of Guatemala), we construct and populate a regional interaction framework (matrix form), identifying 114 possible interactions between 33 hazard sub-types relevant in the Southern Highlands. We also use this evidence to explore networks of multi-hazard interactions and anthropogenic processes that can trigger natural hazards. We present this information through accessible visualisations to improve understanding of multi-hazard interactions in Guatemala. We believe that our regional interaction frameworks approach to multi-hazards is scalable, working at global to local scales with differing resolutions of information. Our approach can be replicated in other geographical settings, with regional interaction frameworks helping to enhance cross-institutional dialogue on hazard interactions, and their likelihood and potential impacts.
