Microplastic research is currently an exciting trend along with global environmental problems. The purpose of this study is to review the development of microplastic research in ASEAN. The researc uses a systematic review method by searching for the keyword “microplastic” and the name of the ASEAN country on the Google Scholar website, Science Direct, and other research paper provider websites. Papers reviewed in 2018 to August 2021 period were then classified based on the components analyzed. The results showed that based on the research location category, the majority of microplastic research was carried out in Vietnam (12/50 articles). The category of research object focused on marine organisms more than terrestrial organisms, the category of microplastic concentration varied because the microplastic sampling method was not standardized, the category of microplastic form dominated by the form of fiber; commonly found in coastal areas. The socio-economic category is not much related to the circular economy. To conclude, microplastic research still has opportunities, especially from a socio-economic perspective.

AbstractAmong the diverse types of merchants active in India during the first half of the second millennium, the ship-owning merchants occupy a prominent position in the coastal areas of western India (especially at ports). These merchants are given distinct epithets nakhuda and nauvittaka, the two terms being occasionally used as interchangeable ones and also in their abbreviated forms in official documents. Known from the medieval Jewish letters of 'India Traders', copper plates, a bilingual inscription, Arabic accounts and epitaphs and Jaina carita (biographical) texts, nakudas and nauvittkas of different religious leanings (Jewish, Muslim and Hindu) illustrate remarkable co-operation and social amity and religious toleration, which underline their importance in the Indian Ocean maritime network prior to AD 1500. Possessing considerable wealth, these ship-owning merchants can be considered as elites in the ports of coastal western India and were also known for their patronage to religious and cultural activities. The paper is presented as a tribute to the memory of Professor Ashin Das Gupta who immensely enlightened us on the ship-owners of coastal western India between 1500-1800.

In 1915, riots broke out in the British colony of Ceylon, the climax of a controversy between Sinhalese Buddhists and a new clement among the commercial “Moors” (Muslims). A court ruling disappointing to the Buddhists, combined with economic complaints against Moors in this centenary of British conquest, led to a communal clash in Kandy during Wesak (Buddha's birthday) in May 1915. During the following two weeks, the riots spread to Colombo and along the west coast, greed increasingly matching creed as a prime motive.The colonial government reacted slowly, allowing disorder to spread, and then changed to a policy of heavy repression of a presumed anti-British uprising at a time the Empire was fighting for survival.Three months of martial law ensued, more deaths caused by police and military action than had occurred during the actual riots. Prominent citizens were arrested without cause. Shoot-on-sight orders were issued, and over 8000 were arrested and imprisoned. This colonial maladministration reflected the gap between officialdom and the colonial peoples. Little evidence of a general plot against government came to light. Since, however, headmen, monks and traders had planned anti-Moor action, especially in coastal areas, the question of conspiracy remains unsettled.The 1915 Riots in Ceylon seriously undermined Ceylonese confidence in British justice, led to peaceful mass protests and a mission to London, and stimulated the maturation of nationalism, with independence as its objective.

Aquatic organisms and pathogens may become major threats to the coastal and marine environment when introduced into a region beyond their natural distributions through ballast water (BW). Coastal currents induced by tides and winds, especially ebb currents, may facilitate the spread of these marine organisms along nearshore and inshore areas. Numerical modelling of hydrodynamics is an effective tool to track the dispersion of these organisms in the receiving water body through BW release. Particle transport models can be used to track the advection and dispersion of these organisms. Alternatively, the difference in salinity of the BW and coastal waters can be used as a tracer to estimate the dispersion pattern. Tides and winds present in the region at the time of BW release are responsible for the dispersal of the particles present in BW discharge. Based on advection and dispersion processes, the transport of the marine organisms present in the BW can be studied using numerical models. Numerical modelling studies were carried out using the 2-D hydrodynamic model MIKE21 HD, to understand the pattern of BW dispersion at select bioregions along the east and west coasts of India. Mangalore Port located along the west coast in Bioregion-I (CIO-I) and Chennai Port on the east coast in Bioregion-II (CIO-II) were selected for the modelling study. Results obtained from ballast water dispersion modelling studies will be useful for developing and assisting port-based ballast water management programmes for CIO-I and CIO-II regions. The currents are predominantly tide driven near the ports situated along the west coast and the circulation exhibited reversals associated with the tidal currents. However, along the east coast of India, the particles largely followed coastal currents - advected either southward or northward under the influence of prevailing coastal currents in the offshore region and tidal reversals showed had less impact. This information proved useful for determining suitable locations for BW discharge and monitoring points for field sampling in connection with BW release.

We report the diversity, distribution and taxonomy of patellogastropod species from the entire mainland Indian coastline. A total of 77 coastal areas with rocky outcrops in the sandy shoreline, covering the entire mainland Indian coastline, were surveyed seasonally (four times a year) during December 2014 to December 2016. Coastal habitat characteristics and the diversity of all groups of limpets from the intertidal areas were recorded. Specimens were identified by external morphological shell and gill characteristics, by the colour of the foot, mantle fringe and radular characteristics. Ecological aspects like habitat preference were also used to distinguish species. Existing diagnostic characters were amended with newer characteristics emerged in our study. Seven species from two families, Nacellidae and Lottiidae, were found along the mainland Indian coastline. Each species is present with several polymorphic forms with different colour banding patterns. Our study revealed distinct variations in the radular teeth at the genus level, but less differences within genera. Patellogastropod diversity was greater along the west coast of India and only Cellana rota was available throughout the mainland Indian coastline.

An annotated checklist of the mantis shrimps (Stomatopoda) occurring in India is compiled from published literature and specimens collected from coastal areas of Gujarat state. A total of 72 species, 35 genera, 10 families and 5 superfamilies reported from Indian waters are listed. Four species were recorded for the first time from Gujarat while one species, Erugosquilla hesperia (Manning, 1968), is confirmed for the first time from India. The maximum number of species was reported from Tamil Nadu (48 species), while fewest species were reported from Karnataka (2 species). The results also suggest that the east coast is more diverse (66 species) than the west coast of India (32 species).

Marine debris is a waste product found in the sea, whether intentionally disposed of or not. This type of plastic waste is the most commonly found in the sea.Plastic waste that found in the ocean will degrade into micro-plastics. Micro-plastics can cause harm to marine organisms and even reach humans through food chain events. In order to reduce the dangers and impacts, it is necessary to introduce the management of coastal areas as part of the ecosystem, through socialization activities to coastal communities. The results of the activities showed interest and positive responses from the community. In addition, the knowledge about the concepts of marine debris, micro-plastics and ecosystems and their relationships has also increased by i.e., of 76%.
