After the catastrophic 2009 bushfires in the state of Victoria, Australia, the State Government provided information and advice, short-term and temporary accommodation as well as financial assistance to bushfire-affected communities. A tension developed between quickly rebuilding housing and re-establishing known social and economic networks versus a slower and more deliberative process that focuses on long-term community outcomes. Whilst there was a widespread assumption that quick rebuilding would be beneficial, resulting in immediate pressure to do so, it became evident that many people were not prepared to, or even did not want to rebuild. Thus it became important to provide time and support for people to consider their options away from the immediate pressures to rebuild that are often inherent in post-disaster recovery processes. This became known as "holding the space" and included the introduction of interim supports such as building temporary villages and other supports which enable people to achieve appropriate interim accommodation without having to rebuild immediately. However, even two years after the bushfires a significant proportion of people remained undecided whether they wanted to rebuild or not. The post-bushfire experience pointed to a number of lessons including the importance of appropriate timing of post-disaster activities, careful targeting of financial assistance, need for developing better and lower cost interim housing options and pre-impact planning. Given the complex nature of rebuilding following a disaster, design professionals should focus not just on the final house, but also look at housing options that blur the distinction between temporary and permanent. Their designs should be quick to build, offer a good quality of life, be affordable for most and be flexible in design for future use.

This paper draws on research conducted after the 2004 Indian Ocean Earthquake and Tsunami in Aceh, Indonesia, where more than 100,000 houses were built by various agencies following the massive disaster. The research reveals that the residents in Aceh rarely see their reconstruction houses as 'complete' and modify these houses to suit their personal needs and aspirations. The relationships between the global and regional forces that drive reconstruction agency housing procurement and production are explored, and compared with the outcomes of user-initiated modifications to the houses. From the hundreds of houses reviewed, here four houses are discussed in detail, built by the Asian Development Bank, representing a global paradigm, and Bank Mandiri, representing a regional paradigm. These houses were modified and extended to varying degrees by their residents, exemplifying the ways in which reconstruction agencies, perhaps inadvertently, empowered residents by enabling them to improve their own housing. The outcomes of this transformation process underscore the advantages of a hybrid between global and regional styles, and the desire of the reconstruction housing residents to recapture some of the local housing culture and reflect regional housing characteristics.

This paper describes the life cycle assessment and life cycle cost analysis of a typical Australian house designs. It evaluates the effect of selected alternative wall assemblages on environmental impacts and life cycle cost over the various life stages of buildings (i.e. construction, operations, maintenance and final disposal). A case study house was used as the base case for all the alternative wall assemblage designs. This paper also reports on alternative wall assemblage designs that were produced with variations in external wall cladding, insulation type and thickness, air gap thickness and position. Each design was varied such that it achieved a chosen star rating. Five exterior wall claddings were selected, typical of the Australian building industry. These claddings were brick, autoclave aerated concrete block, fibro-cement sheet, pine saw logs and weatherboard. The results were analyzed for the whole building on a whole life cycle basis in terms of economic and environmental impact. The implications of life cycle environmental impacts and life cycle costs were evaluated and the optimum assemblage design is reported using optimization algorithm. A set of best solution is found depending on factors: the model assumptions, range of environmental and economic indicators considered, and the chosen quantitative criteria.

Poverty and crime are significant problems in Dhaka, Bangladesh. Many of Dhaka's urban poor are forced to reside in informal settlements, which are typically characterised as 'breeding grounds of evil'. Getting rid of informal settlements is widely seen as the best way of reducing crime. This paper argues this characterisation is misleading and that the processes that generate and perpetuate crime and safety issues in Dhaka are largely external to informal settlements. Drawing on interviews with residents of informal settlements as well as key stakeholders in government and non-government services, this paper suggests that crime and insecurity are perpetuated through a top-down process driven by the powerful through a chain of networks and institutional linkages that capitalise on the extreme vulnerability of the urban poor who live in informal settlements. The findings indicate that until attention is focused on the structural and institutional factors that support these networks, the opportunity for broader, sustainable social change in Dhaka is limited. © 2013 Taylor & Francis.

Vietnam and Bangladesh are countries already impacted by weather-related extreme events. Scientific modelling projections indicate that climate change, and changes to climate variability, will increase risks for both countries in the future. Targeting this challenging contemporary agenda, this paper reflects on the lessons learned from a collaborative research project, funded by the Asia Pacific Network for Global Change Research, which was carried out jointly in the Vietnamese city of Hu¿ and the Bangladeshi city of Satkhira. The focus on secondary cities was intentional as they face unique challenges - a combination of rapid growth and development, adverse climate-related impacts, and in many cases less institutional adaptive capacity than their primary city counterparts. Whilst numerous assessment tool kits already exist, these have typically been developed for rural or natural resource contexts. Therefore, the objective of this action research activity was to develop a flexible suite of participatory assessment tools and methodologies that were refined specifically for the urban context; as well as being easy to use by local practitioners at the city and neighbourhood scales. This paper summarizes the research and stakeholder engagement activity that was carried out before presenting the main findings from each of the case study cities (detailing both climate-related risks and potential adaptation options). This analysis is further extended to include a reflective critique of the assessment process, a comparative analysis of the activity carried out in the two case studies, and the 'South-South' learning process that occurred between project partners. Key findings are then distilled to put forward recommendations in support of climate change assessment activity in secondary cities across the Asia-Pacific region. © 2014 © 2014 Taylor & Francis.

Purpose: After the 2004 Indian Ocean Tsunami, major resettlement programmes were implemented in the affected countries including Sri Lanka and India. New settlements were built from scratch on vacant land, which consisted of building new houses and provision of infrastructure and services. Some of these programmes in Sri Lanka and India were reviewed in an Australian Research Council (ARC) funded research and this paper presents and analyses some of the findings of the research. The paper aims to discuss these issues. Design/methodology/approach: The research is based on interviews of residents and representatives of agencies involved in planning and implementing the resettlement programmes, and on-site observations. The investigation examined critical aspects of settlement development including site planning, transport, drainage, water supply, sanitation, waste management and security. Findings: Very little site planning guidelines were available specifically for resettlement programmes; in both the case study countries, general planning guidelines were applied. Provision and management of infrastructure and services presents great challenges in developing countries as high capital investment and good technical skills for design, implementation and maintenance are required. Some of the resettlement schemes had the advantage of being centrally located and hence had access to schools, health centres and other facilities. However, others were in isolated locations and beneficiaries faced problems in accessing basic facilities. Drainage was a problem - most schemes did not have any surface drainage plan; low areas had not been elevated, slopes not levelled, and land not compacted before construction. Electricity and water supply had been provided in all the programmes, but conditions and quality varied. In many of the schemes, sanitation presented a problem. However, in Chennai, the sewage system worked well and this was one achievement all interview respondents praised. Solid waste management and security posed additional problems. Originality/value: In the global context of increasing frequency and intensity of disasters due to climate change, adequate planning and implementation of reconstruction and resettlement programmes has become more important than ever. In this regard, the lessons gained in this paper should be of value and can provide guidance to post-disaster resettlement programmes in developing countries. © Emerald Group Publishing Limited.

This paper explores the relationship between vulnerability and resilience in the context of informal settlements, using a case study of two barangays in a rural province in the Philippines. Central to the discussion in this paper is whether and how vulnerability and resilience can exist simultaneously. The authors first identify community vulnerability, which is explored through geographical, economic, and physical vulnerability. Another element involves land-related vulnerability characterised by unsustainable land use, poor urban planning, non-existence of building codes and weak land administration. Approximately sixty per cent of all properties in the case study areas are held in informal land tenures. Many of these informal settlers have established houses on land with a high hazard risk - for example, adjacent to rivers, on disused railway reserves and along road corridors. The result is they face the threat of eviction, and may have difficulty returning to their land after disasters.Qualitative analysis of households in the case study areas revealed that the strength of social relationships helps to reduce the vulnerability of the communities. A paradoxical relationship between vulnerability and resilience is evident. Strong community perceptions of their level of resilience to the impacts of disasters are supported by the social domains of the community. They have inbuilt resilience resulting from the perception of disasters as part of life, strong social bonds and government awareness of the validity of the informal settlements.

Scenario method is presented in the literature as a means for engaging heterogeneous stakeholder groups to explore climate change futures and to inform policy and planning for adaptation responses. We discuss a case study project investigating possible interactions between climate change impacts and a proposed major port expansion in Australia. The study engaged participants from the private sector, government and environmental groups, with input from college students from the local area. Semi-structured interviews and a scenario workshop were employed, creating individual space for expression of ideas, then a collaborative space for sharing these, exploring differences of perception and meaning, and developing a set of possible and plausible scenarios. Whilst the workshop resulted in consensus on key issues and proposed actions, intended to inform policy formation and planning, there was an unforeseen lack of short term follow up and of the groups working more closely together. We discuss the reasons for this through reflective critical analysis of both our own process and of contingent factors in the wider contextual environment. We conclude that the basic scenario approach is valuable, but does not itself act as a catalyst for effecting change when multiple agencies, interests and agendas and strong contingent factors are present. © 2012 Elsevier Inc.

In rural settlements of the floodplains in Bangladesh, an intrinsic element is the homestead. The homestead layout is defined by the courtyard, formed by the arrangement of dwelling units and ancillary buildings around a rectangular open space. The courtyard has important physical and functional characteristics derived from local climatic requirements and living patterns. However, particularly in this predominantly Muslim society, the cultural norm of maintaining women's privacy is an important factor behind the development of this archetypal space. Nonetheless, other ethnic communities in the floodplains also often have courtyards, suggesting that it is a regional archetype. The archetypal courtyard is now subject to transformation due to social, economic and environmental changes. If this trend continues, it would signal the loss of an important and long-lasting regional expression that has resulted from the blending of culture, climate and nature. © The Vernacular Architecture Group 2012.

The impact of the extreme heat wave that affected Melbourne, Australia, in two distinct phases in January and February 2009 was severe, with 374 (heat) and 173 (bushfire) excess deaths. Whilst the human health issues have been covered in detail in policy and academic arenas, much less attention has been paid to the adverse impacts on urban infrastructure. Analysis of this event, underpinned by participatory actor-based research, has shown that the impacts were experienced disproportionately across different infrastructure types. For water, telecommunications and airports, the impacts were relatively minor and the impact on rail transport and roads (and to a lesser extent, seaports) was of moderate significance, whereas research findings indicate that the electricity sector was found to be the most vulnerable. This paper focuses on the sectors that were worst impacted: electricity, rail and road transport. Commentary identifies the direct and indirect impacts of the heat event, including associated cascading effects, as well as considering actual and potential adaptation responses both before and after the event. Concluding, the authors reflect on the implications of the heat wave for urban resilience, emphasising the crucial importance of understanding the urban environment as a complex and interconnected system. © 2012 Copyright Taylor and Francis Group, LLC.

The Indian Ocean tsunami of 2004 galvanized world attention like no other natural disaster before. Unprecedented amounts of aid were given and a record number of international aid agencies were involved in relief and recovery operations. Major reviews of the response to the disaster have suggested that the immediate relief effort was better than expected. However, weaknesses in the longer term recovery work were identified within months of the disaster and yet the same weaknesses were being confirmed four and five years later. Even though many studies have been published on the tsunami disaster there are still many lessons to be learnt, particularly in relation to social recovery as distinct from the restoration of destroyed or damaged infrastructure. This paper presents an overview of the findings of a study that was conducted over a period of four years across five different tsunami-affected local areas of Sri Lanka and southern India. The study focused on lessons to be learnt in relation to rebuilding community, restoring livelihoods, recreating an appropriate tourism industry and providing relevant housing and planned settlements for disaster survivors. The paper argues that 'build back better' is possible, but only if 'asset replacement' strategies are replaced by integrated physical and social planning to address local needs in culturally appropriate ways. Much of what the authors advocate may seem to be little more than 'common sense' and many of our findings echo those of many other post-tsunami evaluations. Yet patient and well-integrated approaches to disaster recovery are all too rare in a world that is experiencing so many natural disasters. Because the 2004 tsunami evoked an unprecedented global response it is important to ensure that the lessons of the recovery effort are clearly learnt and this paper aims to convert research findings into a clear strategy for long-term social recovery. © 2012 Taylor & Francis.

Affordability and lifestyle choices in housing are critical to meet basic human needs for shelter, security and wellbeing. The meaning of a house for a particular group of people and what is 'affordable' for a particular community is the critical issue. Dhaka, the capital of Bangladesh, has greater population density and rate of expansion compared to almost any other mega cities of Asia. The historic core of the city known as old Dhaka is a combination of several traditional neighborhoods. Houses in these traditional neighborhoods are not only places to live, rather an integral unit of a social system, having a good mix of place of work and individual expression in living. They also show flexibility and adaptability (with more scope for personalization and individual life style choices) compared to the contemporary housing stock. One of the success factors in these traditional houses is the healthy mix of the income ranges to avoid a ghetto effect of low cost housing. The recent rapid urbanization has led to a discontinuity of the traditional housing form of old Dhaka, leading to a disintegration of the mix of lifestyle choices and affordability. Following popular market trends, they are often replaced by housing blocks in a higher density ignoring the need for a diverse mix. This paper studies the traditional housing of old Dhaka with two case study neighborhoods. Several elements of housing like the common price, materials and construction, space layout, scale, social space, facades, street interface, etc are selected for a qualitative study. Local residents interview, archival records, maps, Plans, figure-ground, aerial images are used to analyze, identify and demonstrate the elements that made them socio-culturally sustainable and affordable for the community. With the analysis, lessons from the traditional housing form that may contribute to the new housing in Dhaka are identified.

Purpose: A set of guidelines widely agreed by the international humanitarian aid community, such as the Sphere Handbook, is currently lacking for permanent housing reconstruction in developing countries. The paper aims to address this gap by reviewing the field and presenting a set of selected examples that offer lessons for informing, developing and promoting wider good practice. Design/methodology/approach: An extensive literature review on post-disaster housing reconstruction in developing countries pointed to the significant impacts of disasters on housing in developing countries and the great challenges involved in the reconstruction process; it also allowed identifying efforts at framing good practice guidelines by humanitarian and other agencies. Findings: The paper finds that, while the review largely indicated the major challenges and shortcomings in the field, it also allowed identifying some examples of good practice and the reasons for their effectiveness. Originality/value: As argued here, there are a number of independent guidelines for post-disaster reconstruction in developing countries, but hardly any which are widely endorsed and can be followed by humanitarian agencies. The paper therefore draws together the key issues and examples of good practice as a basis for informing the development of guidelines. © Emerald Group Publishing Limited.

This paper presents concepts important for understanding the potential of sustainable low-income housing in Vietnam, with a focus on key environmental, socio-economic, and cultural dimensions that bear on its housing sector. It examines challenges for sustainable urban development in Hanoi and HCMC, Vietnam's two main cities. Recognising the current challenges in balancing affordability and sustainability, the study explores Vietnam's lack of adequate and affordable housing and the problem of its urban slums. Synergistic strategies suitable for the Vietnamese context are then suggested for sustainable low-income housing in these two cities.

Traditional rural housing is largely based on the use of locally available natural resources as prime building materials, usually in a process of self-help building undertaken by the community. Such housing is well adopted to a natural environment with widely available resources, and supports people's direct involvement in the construction of their dwellings. However, the advent of a cash economy and current scarcity of natural resources has greatly affected the self-help building process. In rural Bangladesh, affluent households are shifting to manufactured materials and skilled builders, and the quality of housing of low-income households is declining. For the latter, self-help is the only option, and recognition of this fact and of the increasing decline in the quality of their housing has prompted institutional intervention. This paper discusses the Grameen Bank's rural housing programme in Bangladesh which provides loans for manufactured building components for low-income rural households to build houses on a self-help basis. A review of this programme indicates some of its strengths and shortcomings in the context of scarcity of natural building materials and widespread poverty.
