SummaryThe present position of Sri Lanka and its past fit in Gondwanaland are investigated in relation to the development of the Indian Ocean. The 3 stages in the evolution of the Indian Ocean are shown to be controlled by fundamental NW, NS, and NE Precambrian lineament directions in Sri Lanka and South India. These older lineaments were rejuvenated in the Mesozoic–Tertiary to form oceanic transform faults which determined the phases of Indian Ocean floor spreading.

Tuzo Wilson introduces the concept of transform faults, which has the effect of transforming Earth Science forever. Resistance to the new ideas is finally overcome in the late 1960s, as the theory of moving plates is established. Two scientists play a major role in quantifying the embryonic theory that is eventually dubbed ‘plate tectonics’. Dan McKenzie applies Euler’s theorem, used previously by Teddy Bullard to reconstruct the continents around the Atlantic, to the problem of plate rotations on a sphere and uses it to unravel the entire history of the Indian Ocean. Jason Morgan also wraps plate tectonics around a sphere. Tuzo Wilson introduces the idea of a fixed hotspot beneath Hawaii, an idea taken up by Jason Morgan to create an absolute reference frame for plate motions.

The Indian Ocean woven together by transmission of trade, commands the control of majority of the world’s cargo ships, one third of the worlds cargo traffic and two thirds of total world’s oil shipments. The main aim of this paper is to analyse Real GDP, Imports and Exports of Indian Ocean RIM Association Member Nations. Time period of the study is from 1980 to 2019.  Indian Ocean Rim Association for Regional Cooperation (IOR-ARC) contributes 11.7 per cent share in world exports, in case of member nations highest share is of Singapore 2.1 per cent  followed by India and UAE 1.7 per cent, Australia 1.5 per cent, Thailand and Malaysia 1.3 per cent. Indonesia, South Africa, Bangladesh, Oman, Iran, Islamic Republic of, Sri Lanka the share in world exports is less than 1 per cent.

The Impact

Purpose The impact of disasters caused by natural hazards on people in affected communities is mediated by a whole range of circumstances such as the intensity of the disaster, type and nature of the community affected and the nature of loss and displacement. The purpose of this paper is to demonstrate the need to adopt a holistic or integrated approach to assessment of the process of disaster recovery, and to develop a multidimensional assessment framework. Design/methodology/approach The study is designed as a novel qualitative assessment of the recovery process using qualitative data collection techniques from a sample of communities affected by the Indian Ocean tsunami in Eastern and Southern Sri Lanka. Findings The outcomes of the interventions have varied widely depending on such factors as the nature of the community, the nature of the intervention and the mode of delivery for donor support. The surveyed communities are ranked in terms of the nature and extent of recovery. Practical implications The indices of recovery developed constitute a convenient tool of measurement of effectiveness and limitations of external interventions. The assessment used is multidimensional and socially inclusive. Originality/value The approach adopted is new to post-disaster recovery assessments and is useful for monitoring and evaluation of recovery processes. It also fits into the social accountability model as the assessment is based on community experience with the recovery process.

2004 Tsunami

The 2004 Indian Ocean tsunami caused enormous loss of lives and damage to property in Sri Lanka and in several other countries bordering the Indian Ocean. One way of mitigating potential loss of lives from a similar event in the future is through early warning and quick evacuation of vulnerable coastal communities to safer areas, and such evacuation planning is usually carried out based on inundation maps. Accordingly, the present paper outlines the numerical modelling carried out to develop tsunami inundation maps on a grid of 10 m resolution for three cities on the south coast of Sri Lanka. The results give the tsunami arrival time contours and the spatial distribution of the extent of inundation, the maximum flow velocities as well as the hydrodynamic force in these three cities due to an event similar to the 2004 tsunami.

On 26 December 2004, a devastating tsunami struck the coasts of 12 nations on the Indian Ocean. Over 300,000 people in 12 countries died in the wake of the tsunami, millions of housing units were damaged or destroyed, economies were devastated, and ecosystems were disrupted. The lessons from this catastrophe have worldwide implications, but the tragedies were local. Sri Lanka and the Aceh province of Indonesia suffered most of the casualties. The Sri Lankan experience illustrates that the recovery can be hindered by a country's social and political conditions. Challenges to recovery include the need for centralized coordination and organization, planning and development control, gathering planning data, political leadership, equitable distribution of recovery assistance, and disaster education.

India perceives the entire Indian Ocean region (IOR) as its strategic backyard and regards itself as a “security provider” in the region. This view, of course, is not shared by many, mainly by the Chinese who often state “the Indian Ocean is not India’s backyard.” To reinforce its own perceptions and stem its eroding influence in the region - India has stepped up its efforts in enhancing its relations in general and on maritime security in particular with its island neighbours, an aspect that is being extended to the entire South Asian neighbourhood incrementally. The importance of the Mahanian concept of utilising Sea Power for the achievement of national objectives has led to the realisation amongst a normally ‘sea blind’ Indian bureaucracy to become more proactive. This article explores the maritime policy of India with regard to its neighbouring littoral states in the Indian Ocean.

Calymperes Sw. ex Weber (1813) is the second largest genus in the family Calymperaceae (after Syrrhopodon Schwägrichen (1824: 110)) and comprises approximately 53 accepted species worldwide, mainly distributed in tropical and subtropical regions (Frey & Stech 2009). It is easily separated from other genera of the Calymperaceae by its distinctive sporophytes, which lack peristome teeth, but possess a persistent calyptra. Calymperes palisotii Schwägrichen (1816: 334) is an extremely variable species, occurring from the Neotropics, across Africa, through the islands of the Indian Ocean, to India and Sri Lanka, rarely penetrating eastwards into Indochina and Malesia (Ellis 2018). In their broad concept, Reese & Mohamed (1985) treated many species of Calymperes as synonyms of C. palisotii. These included C. moluccense Schwägrichen (1824: 99) a highly variable species from Malaysia and Oceania. Based on an examination of a wide range of materials of C. palisotii, Ellis (1987) considered that C. moluccense was quite different from C. palisotii, and reinstated C. moluccense as a good species, placing in synonymy with the latter, several taxa also previously regarded as synonyms of C. palisotii (Ellis 1987).
