“…This external N input also supported the growth of salt-tolerant estuarine micro and macroalgae that were attached to the P. coarctata leaf and rhizome structures as epiphytes, as inferenced from δ 13 C isotopes of biomass (Figure 5c). This showcases, the influence of seasonality on the P. coarctata biomass generation and its contribution towards the total ecosystem Corg stocks, which has been observed for saltmarsh ecosystems around South Asia (Billah et al, 2016;Hena et al, 2007;Hossain et al, 2016;Perera et al, 2022;Prasad et al, 2014) and in other areas (Chen et al, 2016;Human et al, 2022;Miller et al, 2023;Qu et al, 2019;Yuan et al, 2022).…”

Despite saltmarshes being considered as nature-based solutions (NbS) towards climate change mitigation, India’s saltmarsh ecosystems are least studied. This study quantifies the seasonal variation in carbon stocks mono-specific saltmarsh species (Porteresia coarctata) and its potential to play an important role in India’s climate change mitigation plans. Seasonal (pre-and post-monsoon) sampling of P. coarctata surface water, biomass and 30 cm sediment core was collected across four locations on the east coast of India to quantify sediment dry bulk density (DBD), organic matter (OM%), organic carbon (Corg%), Corg stocks of sediment and biomass, total carbon (C%) and nitrogen (N%) and stable isotopes of δ13C and δ15N. In general, the sediment DBD, OM and Corg of P. coarctata meadows was higher in post-monsoon and was influenced by salinity and pH changes. Isotope (δ13C) modelling of various sediment C sources suggested, particulate organic matter (POM) contribution was highest (0.04-0.79%) followed by P. coarctata (0.01–052%) and other macrophytes across our study locations. The seasonal variation of δ13C showed increased contribution of marine derived particulate and dissolved organic matter into P. coarctata meadows in post-monsoon season. Heavier δ15N values were observed in post-monsoon season suggesting anthropogenic input, that was utilized by P. coarctata to increase its above and below-ground biomass and shoot density. The combined ecosystem (30 cm sediment + biomass) Corg stocks of P. coarctata was 1.7-fold higher in post-monsoon (4021.20± 917 Mg C) compared to pre-monsoon (2297.36 ±647 Mg C) season among the four locations with a sediment Corg contribution >70%. Based on the International Panel for Climate Change Tier II assessment the P. coarctata meadows (443 ha) can help in avoiding the pre and post-monsoon emissions of 8431.34 and 14757.84 Mg CO2 respectively. The combined price of the total CO2 equivalent stored in P. coarctata meadows in pre- and post-monsoon is US$ 14.50 and US$ 25.38 million respectively. Further studies quantifying the NbS potential of P. coarctata mono-specific and mixed meadows of India’s coast is needed along with integration of saltmarsh ecosystems into India’s National Action Plan on Climate Change.

“…Seagrasses are generally marine flowering plants that form ecologically and economically important habitats in coastal zones around the globe [1]. They are marine angiosperms inhabit and support different forms of life from different ecosystems while they co-exist with other ecosystems, including, estuaries, mangroves, coral reefs, and coastal wetlands [2][3][4][5]. The services that are provided by seagrass meadows are very wide, from recreation to carbon sequestration, where the economic valuation is considerably high compared to the other ecosystems [6][7][8].…”

The seagrass ecosystems found in the marine and coastal areas, with substantial eco-nomic and ecological services and span all over the globe excluding the Antarctic region. The Coral Triangle and Southeast Asia are recognized as a worldwide hotspot of seagrass species and habitats, encompassing 10-21 species of seagrass in every na-tion, although the study, understanding, and quantity of publications on seagrass eco-systems are rather limited in the region, including Malaysia. Malaysia contains 18 seagrass species from three families, which occupy 16.8 km2of coastal area, where the study and discovery of seagrass species and meadows began in 1904 with the re-port of Beccari. All of the published papers reviewed reported on Malaysian seagrass-related research, which was divided into nine topic groups: biology and distribution, carbon sequestration, fauna, remote sensing, impact and pollution genetic study, res-toration, microbiological investigation, and others. The extensive study of the seagrass ecosystem began in 1993, and we have identified 183 published papers from Scopus, 141 publications from Web of Science, and 42 from Google Scholar. However, the average trend of the number of publications from 1993 to 1999 was 0.71 ± 0.36, while from 2000 to 2022 was 7.70 ± 1.16 followed by the average trend of the yearly number of publications was 6.78 ± 1.08. The highest number of publications was found on faunal categories (43.17%), followed by biology and distribution (21.85%). The num-ber of articles that were published on Malaysian seagrass meadows each year has been discovered to be rising, which indicates that the trends in seagrass study and publish-ing were progressively garnering the attention of researchers, academics, and the gov-ernment. However, to better understand the sustainable ecology and ecosystem ser-vices provided by seagrass habitats, an emphasis on certain research niches, such as the genetic study of flora and fauna in seagrass meadows, microbial ecology, and res-toration as well as conservation of seagrass species might be helpful.

Irawan A, Supriharyono, Hutabarat J, Ambariyanto. 2018. Seagrass beds as the buffer zone for fish biodiversity in coastalwater of Bontang City, East Kalimantan, Indonesia. Biodiversitas 19: 1044-1053. The purpose of this study was to demonstrate theimportance of seagrass beds as a buffer zone for fish biodiversity in a coastal ecosystem. The sampling of seagrass and fish were done inseagrass beds associated with mangrove (ST1) and coral reef (ST2). Sampling period was executed from May 2011 to May 2017.Sampling was done on the lowest tide with a six-month interval. Seagrass sampling was carried out using line transect, and fishsampling was performed using set net (belat local name) operated by local fisherman. The results showed that seagrass beds at ST1composed of C. rotundata and E. acoroides and that at ST2 composed of C. rotundata, E. acoroides, H. pinifolia, H. minor and T.hemprichii. The total number of individual was 42574 divided into 112 fish species. There were 17 species (population: 15.18%)associated explicitly with ST1 and 39 species (population: 34.82%) specifically associated with ST2 while 56 fish species (population:50.0%) were prevalently spread in both stations. This research proved the existence of seagrass beds as a buffer zone for fishbiodiversity.
