Economic development perspectives of post-disaster infrastructure reconstruction: Post-tsunami reconstruction in Sri Lanka

Sri Lanka was found to be a disaster prone country in the recent past. The impact is more severe when developing countries are faced to various natural or man-made disasters. Impact appears in many forms; loss of lives and property, economic impact, social impact etc. As a developing country, Sri Lanka is much more concerned with the country’s economic development. Therefore, it is wise to look into post-disaster activities in development perspectives and integrate disaster risk reduction concerns into economic development activities. This paper reveals the importance of post-disaster infrastructure reconstruction in economic development. A comprehensive literature review was carried out regarding the role of infrastructure in disaster management, economic development together with the key indicators of economic development

Exploring good practice knowledge transfer related to post tsunami housing re-construction in Sri Lanka

Sri Lanka was badly affected by the tsunami that occurred on 26th December 2004. The tsunami destroyed about two-thirds of the Sri Lankan coastline and affected more than 1,000,000 people. It does not only affected the lives of the community, but also had a devastating effect on their housing and livelihoods. The overall loss of 100,000 or more houses due to the tsunami proved to be a major challenge to the emergency response teams and disaster planners. Although several major disasters of varying magnitudes have occurred in the world, the body of knowledge related to post-disaster housing reconstruction and rehabilitation appears fragmented and poorly integrated. This paper attempts to fill this theoretical gap by focusing on the extent to which good practice knowledge transfer helps in overcoming this problem for more effective and efficient delivery of post-tsunami housing in Sri Lanka. The paper applied knowledge transfer principles within the context of the two housing reconstruction strategies employed in post-tsunami housing reconstruction in Sri Lanka; namely donor-driven housing and owner driven housing. The results of this study reveal that the knowledge transfer within this context cannot be simply copied and inserted from one context without any localisation. Therefore, the paper proposes a high-level abstraction of the core principles of community engagement through participatory techniques associated with appropriate capacity and capability building techniques that will enable the various stakeholders to create a new application to suit the appropriate context of the transfer destination (post-tsunami context in Sri Lanka)

Disaster risk reduction strategies and post-disaster infrastructure reconstruction

World’s vulnerability to natural disasters has increased over the last few years. Hence, mainstreaming disaster risk reduction into constructed facilities has taken up an important role in the whole of the disaster management cycle. This paper aims to study the importance of mainstreaming disaster risk reduction in to postdisaster infrastructure reconstruction and the initiatives taken by the relevant bodies in order to minimize the future natural risks in reconstruction of infrastructure. Reconstruction serves to reinforce the society or sometimes even increase the vulnerability of the society. Therefore, investment in the physical infrastructure for disaster management is essential as it can result in reduced loss of lives in case of a disaster, do withstand disasters, reduces the risk of failure and thus contributes to disaster reduction and prevention. However, infrastructure reconstruction programs should aim to change the vulnerable conditions for the development of the country. It is well identified that all critical infrastructure facilities must be designed to a given level of safety from disaster impact. Moreover, such guidelines must be provided to designers and adequate monitoring system be in place. Thus, the routine reconstruction of infrastructure should, for example, incorporate design features that protect them from known hazards. The research reveals strategies used in general and in specific to the infrastructure sectors in addressing the above issues. A comprehensive literature review was carried out on the present situation with regard to above-mentioned measures. This research expects to strengthen the infrastructure reconstruction process by reporting the practical measures taken in reduction of future risks in the posttsunami infrastructure reconstruction of Sri Lanka

Challenges and benefits of LED retrofit projects: a case of SALIX financed secondary school in the UK

The recent surge in light emitting diode (LED) lighting retrofitted into schools in the UK is as a result of the UK Government’s 2050 zero carbon pledge. However, the benefits and consequences of LED retrofit projects for staff and enablers and stakeholder knowledge gaps about LED lighting retrofitting have not been fully explored. The aim of this research is to determine the amount of savings in cost, carbon reduction and kilowatt usage and to confirm if repayment from energy and cost savings derived from LED retrofit school projects funded through the SALIX funding option in the UK would be enough to service the loan. Thus, it examines monetary and non-monetary benefits, internal project stakeholder knowledge gaps and the consequences of LED retrofit for the staff and enablers of a large community college in the UK which is funded through the SALIX funding option. Design/methodology/approach: The methodology relied on a hybrid research approach of a case secondary school through the review of literature, analysis of secondary data, focus group and questionnaire survey. The focus group consists of six key project stakeholders. The secondary data was sourced from the Project IGP [Individual Grade Proposal] and the Positive Energy Report from Zenergi, and the closed online questionnaire survey was used to sample 150 teaching staff and school enablers. Findings: The findings show that stakeholders lack project knowledge, trust and expertise/project comprehension. This is in terms of baseline information, LED technology/management, payback modalities, management of risks and ethical issues around environmental impact. The forecasted SALIX savings were not achieved in real-time, partly because it does not take into consideration the increase in energy costs over the payback period. However, the LED retrofit creates efficiencies; drives down energy costs and energy usage; and drives carbon reduction, helping pupils’ learning, improving productivity and performance, and finally leading to a better lighting environment for the school community. Originality/value: The study will help schools in the UK that intend to access SALIX finance for LED retrofits to understand the challenges and mitigate the risks. It will also help the government to understand the importance of adjusting the payback modalities to the base price when the retrofit was carried out for real-time savings to be made. The research would be useful in ensuring the proactive involvement of all the identified stakeholders in understanding the challenges and what the function entails

Impact of culture towards disaster risk reduction

Number of natural disasters has risen sharply worldwide making the risk of disasters a global concern. These disasters have created significant losses and damages to humans, economy and society. Despite the losses and damages created by disasters, some individuals and communities do not attached much significance to natural disasters. Risk perception towards a disaster not only depends on the danger it could create but also the behaviour of the communities and individuals that is governed by their culture. Within this context, this study examines the relationship between culture and disaster risk reduction (DRR). A comprehensive literature review is used for the study to evaluate culture, its components and to analyse a series of case studies related to disaster risk. It was evident from the study that in some situations, culture has become a factor for the survival of the communities from disasters where as in some situations culture has acted as a barrier for effective DRR activities. The study suggests community based DRR activities as a mechanism to integrate with culture to effectively manage disaster risk

The Double-peaked Radio Light Curve of Supernova PTF11qcj

We present continued radio and X-ray follow-up observations of PTF11qcj, a highly energetic broad-lined Type Ic supernova (SN), with a radio peak luminosity comparable to that of the γ-ray burst (GRB) associated SN 1998bw. The latest radio observations, carried out with the Karl G. Jansky Very Large Array, extend up to ~5 yr after the PTF11qcj optical discovery. The radio light curve shows a double-peak profile, possibly associated with density variations in the circumstellar medium (CSM), or with the presence of an off-axis GRB jet. Optical spectra of PTF11qcj taken during both peaks of the radio light curve do not show the broad Hα features typically expected from H-rich circumstellar interaction. Modeling of the second radio peak within the CSM-interaction scenario requires a flatter density profile and an enhanced progenitor mass-loss rate compared to those required to model the first peak. Our radio data alone cannot rule out the alternative scenario of an off-axis GRB powering the second radio peak, but the derived GRB parameters are somewhat unusual compared to typical values found for cosmological long GRBs. On the other hand, Chandra X-ray observations carried out during the second radio peak are compatible with the off-axis GRB hypothesis, within the large measurement errors. We conclude that VLBI measurements of the PTF11qcj radio ejecta are needed to unambiguously confirm or rule out the off-axis GRB jet scenario
