    Analysis of disaster management frameworks to evaluate the hazard induced risks of coastal communities
    (2020) Rathnayake WKD; Siriwardana CSA; Dissanayake PBR; Bandara CS
    Natural hazards were recognized globally as the most pressing risk in terms of impact and probability of occurrence. This context presses the need for strong, effective risk management mechanisms in the field of disaster management. Yet the ever increasing casualties, economic losses due to natural hazards raise the question on the effectiveness of respective mechanisms to mitigate such. That leads to the objective of this research work, to find engineered solutions for the disaster risk management mechanism to be more effective. The research work conducted in three phases. First a literature survey to identify the risk management principles, disaster management principles, and disaster and risk relativity and evaluation methods. The next phase is framework development. Number of frameworks were developed as part of the research work to evaluate the effectiveness of a disaster management mechanism and to capture the details of a given mechanism. Third phase is the three case studies in three countries, Sri Lanka, Myanmar and Maldives. Collected data were then analyzed to capture an ideal disaster management mechanism. It was identified that there are number of factors can include in to a disaster management mechanism from a risk management perspective. Also it was identified that the developed frameworks do capture the details of a disaster management mechanism in a satisfactory way. There are number of practices countries can share within to enhance the mechanisms. Also the research work concluded with an institutional ideal arrangement in a disaster risk management perspective.

    Integration of the disaster risk reduction (DRR) and disaster resilience mechanisms into the green building rating systems-case study on the green SL Rating system of Sri lanka
    (2020) Abeysinghe AASE; Siriwardana CSA; Dissanayake PBR; Bandara CS
    The rapid growth of global human population necessitates the facilitation of increased number of buildings and other infrastructure. Primarily in economically developing nations, these buildings are designed only complying with local level regulations and standards which are outdated and not carrying allowance for disaster risk reduction and climate changes such as global warming. In the context of Sri Lanka, unplanned developments and expansions due to urbanization has made the community and their assests and resources vulnerable to natural hazards like floods, landslides, tsunami, droughts, coastal erosion and cyclones. Out of them, floods, landslides, heavy winds and Tsunamis have caused the highest number of damages to buildings and loss of human lives during the period of 1965 to 2019 and hence can be considered as significant in providing action. Since anthropogenic natural hazards have kicked off to occur more frequently, it is vital to erect buildings, especially community shelters, in a way that they can withstand strains and pressures that will be imposed by changing future trends. Striving to achieve its vision, the Green Building Council of Sri Lanka (GBCSL) is playing a commendable role in maximizing Sri Lanka’s greener practices and sustainability through the development of green rating tools for buildings and infrastructure, recognition of green materials to be used as construction materials and conducting professional training programs, green talks, workshops and many CSR activities. It has inculcated sustainability and resilience in their rating systems and practices, through enhancing the usage of locally manufactured and less energy consumed material and reducing resource and energy consumption in buildings, it has not yet been properly recognized the need to inculcate the Disaster Risk Reduction (DRR) mechanisms in to their rating systems. Therefore, to ensure an economically viable, environmentally-friendly and socially recognized growth in Sri Lanka, it’s high time that the sustainable disaster risk reduction and mitigation measures are incorporated in the design, construct and operation phases of buildings. Thus, this study was carried out to incorporate the DRR and disaster resilience structural and non-structural mechanisms for floods, landslides and heavy winds into the existing categories of the rating tools for buildings, cities and transportation infrastructure of the GREEN SL Rating System for Built Environment in Sri Lanka in transforming the existing construction industry of Sri Lanka into a disaster resilient and a sustainable one.
