The resilience and adaptation for the disaster mitigation with special reference to coastal defensive measures used in sri lanka

Abstract

The resilience and adaptation for the disasters caused by climate change is the most emerging trend and the need of this century. Most of the countries including Sri Lanka, the mitigative strategies used are mostly sole implementations of engineering and nature-based, with a greater gap in-between. For the fulfilment of this gap, the role of Landscape architect is vital in the planning and design stages, from micro to macro levels in development projects. This research is concentrated on the coastal resilience and adaptation as the vulnerability for the coastal disasters is high in Sri Lanka as a tropical island. Here the effectiveness, resilience and adoptive abilities are discussed about the mitigative measures used so far in the local coastline. The methodologies used are the map analysis, photographic survey, re-synthesis of the previous research outcomes and timely evolution studies to analyse the effectiveness. The usage of integrated methods in disaster mitigation is the next lap of development in Sri Lanka. To use an integrated system of defensive measures, there should be common factor to be taken into consideration. The research is an attempt of revealing a common factor as such by investigating coastal defences, in order to apply in the integrated measures applications as post described. The usage of Landscape architectural solutions which are a hybrid of measures is a basic necessity in the development process, which is the sustainable no-regret strategy for the resilience and adaptation for the disaster mitigation.
