TL;DR: Malvarez et al. as mentioned in this paper developed the Coastal Hazards System (CHS), an innovative statistical and probabilistic framework that serves as the foundation of the CHS, which includes comprehensive characterization of storm climatology, high-resolution numerical modeling, and advanced joint probability analysis of atmospheric forcing and primary storm responses.
Abstract: Nadal-Caraballo, N.C.; Campbell, M.O.; Gonzalez, V.M.; Torres, M.J.; Melby, J.A., and Taflanidis, A.A., 2020. Coastal Hazards System: A Probabilistic Coastal Hazard Analysis Framework. In: Malvarez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 1211-1216. Coconut Creek (Florida), ISSN 0749-0208.Coastal hazards such as storm surge, waves, currents, wind, and rainfall associated with extratropical and tropical cyclones (e.g., hurricanes) can have devastating effects and threaten the lives of millions of people living along the world's coastlines. This has led to the development of the Coastal Hazards System (CHS), an ambitious program with the primary goal of quantifying extreme coastal hazards due to both tropical and extratropical cyclones. The CHS currently covers all U.S. hurricane-prone coastlines along the Gulf of Mexico, the Atlantic seaboard, Puerto Rico, and the U.S. Virgin Islands, as well as regions affected only by extratropical storms like the Great Lakes. The Probabilistic Coastal Hazard Analysis (PCHA) is an innovative statistical and probabilistic framework that serves as the foundation of the CHS. This framework includes comprehensive characterization of storm climatology, high-resolution numerical modeling, and advanced joint probability analysis of atmospheric forcing and primary storm responses, including associated aleatory and epistemic uncertainties. New PCHA advancements overcome limitations of previous joint probability methods by integrating meta-Gaussian copula for the computation of storm probabilities, spatially-varying bias and uncertainty quantification, and Gaussian process metamodel (GPM) based on existing CHS synthetic tropical cyclones. GPM emulates the response of computationally-expensive hydrodynamic models and enables the generation of augmented tropical cyclone suites, consisting of up to millions of storms, for optimal coverage of the parameter and probability spaces. The CHS also includes a database and a web-based data mining and visualization system for public distribution of high-fidelity probabilistic, atmospheric and hydrodynamic modeling results. PCHA results are distributed along with the corresponding metadata, in self-describing data formats for easy and efficient use by engineers, planners, economists, emergency managers, and researchers.

Abstract: Sun, C., 2020. Digital finance, technology innovation, and marine ecological efficiency. In: Yang, D.F. and Wang, H. (eds.), Recent Advances in Marine Geology and Environmental Oceanography. Journal of Coastal Research, Special Issue No. 108, pp. 109–112. Coconut Creek (Florida), ISSN 0749-0208.A growing consensus recognizes that finance and technology have important impacts on marine ecological efficiency. This paper first summarizes the tendency of marine green factor productivity by using the data envelopment analysis-Malmquist model. To understand the influence of digital finance on marine ecological efficiency, studying the data of coastal provinces in China from 2011 to 2018 provides an opportunity to discuss the theoretical relationship, where the effects of economic variables such as industrial structure and fiscal expenditure are well controlled. By using the fixed-effect model and instrument variables, the regression result shows that digital finance can promote marine ecological efficiency, which is more obvious in southern coastal provinces. In conclusion, it is important to strengthen the development of digital finance in coastal areas, encourage scientific and technological innovation, and promote ecological efficiency.

Coconut Creek (Florida), ISSN 0749-0208.Jakarta coastal area is a part of North Jakarta which has a boundary to the Java Sea. Coastal flood from the Java Sea was not a new case in North Jakarta, the situations occurred due to sea-level rise. The conditions of coastal flood in Jakarta can be worsening by land subsidence in Jakarta coastal area. The land subsidence in Jakarta coastal area was occurred in many years and detected by geodetic measurement methods such as GPS and leveling surveys. The study about land subsidence in Jakarta coastal area needed to be updated because it could affect the urban development. This study presents the mean vertical deformation map using Stanford Methods for Persistent Scatterer (StaMPS) for time-series analysis on the Sentinel-1 data archives in the period of March 2017 through April 2020 in both ascending and descending track. The comparison of mean vertical deformation map between two tracks shows a good correlation in terms of displacement patterns with slightly different in 4 individual chosen points that show a high deformation at rates between 30 mm/year and 40 mm/year. The area chosen in this study known as a reclaimed area and the subsidence occurred due to young alluvium consolidation that not supported the maximum compression from a lot of buildings. These approach methods in this study that using StaMPS could be used to monitor land subsidence from all-terrain.

Abstract: Monteiro, R. and Ferreira, J.C., 2020. Green infrastructure planning as a climate change and risk adaptation tool in coastal urban areas. In: Malvarez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 889–893. Coconut Creek (Florida), ISSN 0749-0208.The green infrastructure of Setubal is an environmental and land management planning tool that recognizes the territorial ecological systems and guides in a sustainable way the occupation and transformation of the territory, and it was developed based on three main elements – georeferenced-based information, a quantitative and qualitative analysis of the territory, and technical meetings. The green infrastructure of Setubal covers about 90% of the municipality – including urban areas –, 30% more than the land covered by other protected areas restrictions owned by the municipality – Arrabida Natural Park, Natural Reserve of Sado Estuary and Natura 2000 Network.

TL;DR: Watson et al. as mentioned in this paper provided a contemporary assessment of sea-level rise around Australia to the end of 2018, based on all available tide gauge records and satellite altimetry.
Abstract: Watson, P.J., 2020. Updated mean sea-level analysis: Australia. Journal of Coastal Research, 36(5), 915–931. Coconut Creek (Florida), ISSN 0749-0208.As an island nation with 60,000 km of open coastline and extensive margins of increasingly urbanised intertidal estuarine foreshores, Australia is critically exposed to the global threat posed by rising sea levels into the future. This study provides a contemporary assessment of sea-level rise around Australia to the end of 2018, based on all available tide gauge records and satellite altimetry. The study provides the first national assessment of vertical land motion (VLM) around the coast, identifying margins more prevalent to subsidence, which in turn exacerbate the localised effects of a rising global mean sea level. These areas include coastlines between Townsville and Coffs Harbour, Burnie to Port Pirie, and Fremantle to Wyndham. State-of-the-art time-series analysis techniques applied to all high-quality tide gauge records exceeding 75 years in length (four sites) enabled improved insights into the temporal resolution of current rates of rise and accelerations in mean sea level around Australia than were previously available. Averaged across these four records in 2018, approximately 40% of the “relative” velocity observed (∼2.2 ± 1.8 mm/y, 95% confidence limit [CL]) is attributable to VLM. When corrected for VLM, only the Fort Denison site exhibits “geocentric” mean sea-level velocity in 2018 exceeding 2 mm/y. The average geocentric velocity across all four sites in 2018 equates to 1.3 ± 2.0 mm/y (95% CL). Interestingly, each long record exhibits similar temporal characteristics, whereby a low point in the velocity time series occurs sometime in the period from 1970 to 1990, after which velocity increases over time to a peak occurring sometime after ca. 2010, suggesting the presence of a small acceleration (albeit not statistically different to zero at the 95% CL) in the record.

TL;DR: In this article, Malvarez et al. analyzed the partial foredune recovery from the 2013-2014 winter at Truc Vert beach using ground-penetrating radar (GPR) and through the coastal dune internal structure.
Abstract: Robin, N.; Billy, J.; Castelle, B.; Hesp, P.; Laporte-Fauret, Q.; Nicolae-Lerma, A.; Marieu, V.; Rosebery, D.; Bujan, S.; Destribats, B., and Michalet., 2020. Beach-dune recovery from the extreme 2013-2014 storms erosion at Truc Vert Beach, Southwest France: New insights from ground-penetrating radar. In: Malvarez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 588–592. Coconut Creek (Florida), ISSN 0749-0208.Foredunes are efficient natural coastal defenses acting as protective barriers during storm events. A striking example is the response of coastal dunes along the Aquitaine Coast (SW France) to the 2013-2014 winter, which was the most energetic winter since at least the mid-20th century in most of the NE Atlantic. The aim of this study is to analyze the (partial) foredune recovery from the 2013-2014 winter at Truc Vert beach using ground-penetrating radar (GPR) and through the coastal dune internal structure. Geophysical data was compared with semi-monthly DGPS topographic data of the beach, UAV-photogrammetry and Airborne LiDAR surveys of the coastal dune. Three main recovery phases were identified from the 2013-2014 winter: (i) aggradation of the upper-beach and dune front-crest during the post-storm summer; (ii) distinct phases of incipient dune-foot development with dune-crest stability during the following year, and (iii) since 2016, aggradation of both dune-foot and dune front-crest tending towards an equilibrium profile. This study shows that GPR surveys, combined with chronological topographic data, is an efficient tool to provide comprehensive understanding of the beach-dune system evolution at a decadal scale. This approach opens new perspectives to document foredune recovery timing and magnitude along sandy coasts.
TL;DR: Gough et al. as discussed by the authors examined the impact of coastalization on day-to-day temperature variability along China's east coast and found that the variation of the minimum temperature of the day was the clearest indicator of coastalisation, particularly when the effects of latitude were included.
Abstract: Gough, W.A. and Shi, B., 2020. Impact of coastalization on day-to-day temperature variability along China's east coast. Journal of Coastal Research, 36(3), 451–456. Coconut Creek (Florida), ISSN 0749-0208.Annual day-to-day temperature variability is examined for 16 urban areas along China's east coast. This day-to-day temperature framework was used to compare these cities and to discern differences between coastal locations and those inland from the coast. The day-to-day variation of the minimum temperature of the day was found to be the clearest indicator of coastalization, particularly when the effects of latitude were included. In addition, this metric was found to be superior and more nuanced than traditional measures of continentality and coastalization. An inland transect from Shanghai Pudong to Nanjing within the Yangtze River delta is suggestive of the relationship between the day-to-day temperature metrics and inland displacement and elevation. This work supports the further utility of the day-to-day temperature variation framework in detecting subtle changes in the thermal response to local meteorological and geographical features and may provide a useful tool for assessing marine impacts on climate data.

Abstract: Finkl, CW and Makowski, C, 2020 Coastal Belt Linked Classification (CBLC): A system for characterizing the interface between land and sea based on large marine ecosystems, coastal ecological sequences, and terrestrial ecoregions Journal of Coastal Research, 36(4), 677–693 Coconut Creek (Florida), ISSN 0749-0208The Coastal Belt Linked Classification (CBLC) is a novel approach based on interpretation of satellite images and assimilation of collateral data to characterize coastal belt segments that function as discrete interfaces between land and sea This method is based on the formulation of concepts derived from the Biophysical Cross-shore Classification System (BCCS), the worldwide and regional-scale Large Marine Ecosystems (LME) classification, and the global distribution of terrestrial Ecoregions (ER) The coastal belt, a zone that extends across the shore from marine environments to inland terrestrial habitats, has recently been described in terms of cross-shore catenary sequences based on biophysical attributes of geomorphology and ecology The CBLC formulates a cross-shore coastal classification by conjoining the Dominant Catenary Sequences (DCS) and Coastal Ecological Sequences (CES) with marine (LME) and terrestrial (ER) ecological systems; thus, a linkage is now provided between marine and terrestrial areas across coastal belts that function as transitional succession zones This study proposes to combine the traditionally separated tripartite marine, coastal, and terrestrial delineations by melding them into a single descriptive code sequence that can be ascertained from interpretation of Google Earth satellite imagery and accessing collateral data via interactive LME and ER online platforms Development of the CBLC is facilitated by the fact that LME and ER units are codified by numerals that are easily added to the formulated CES as prefixes and suffixes The resulting combined alphanumeric code brings together a trove of information at different levels of investigation (Levels I – IV) that was heretofore not easily assimilated This linkage of DCS and CES catenas with marine LME and terrestrial ER units brings added advantage to the interpretation of satellite imagery of the world's coasts, as it allows coastal belts to be viewed within the context of transitional interfaces between connected marine and terrestrial parameters Recognition of coastal belts as interfacial bridges linking terrestrial and marine ecosystems into one codified descriptor sequence allows for cross-shore transects to be defined in the form of the Coastal Belt Linked Classification (CBLC) and provides an opportunity to fully comprehend the dynamic nature of coastal zones around the world

TL;DR: Mylroie et al. as mentioned in this paper analyzed the Bahamian seafloor margin caves and the position of mid-to late Pleistocene sea level in the Bahamas and found that 26 caves with associated elevations between +8 and +24 m above modern sea level are found spanning the northwest to the southeast boundaries of the archipelago.
Abstract: Mylroie, J.; Lace, M.; Albury, N., and Mylroie, J., 2020. Flank margin caves and the position of mid- to late Pleistocene sea level in the Bahamas. Journal of Coastal Research, 36(2), 249–260. Coconut Creek (Florida), ISSN 0749-0208.The Bahamian Archipelago has abundant fossil coral reefs and related subtidal deposits as evidence of the last interglacial (marine isotope stage [MIS] 5e) sea-level highstand; evidence of earlier highstands from the mid-Pleistocene is limited and controversial (excepting Mayaguana Island). Data from flank margin cave elevations, used as a sea-level proxy, were initially interpreted to demonstrate an MIS 5e origin derived from ∼60 mapped caves across the archipelago. A new analysis of cave morphologies and distribution has now produced 363 maps of flank margin caves, demonstrating for the first time that 26 caves with associated elevations between +8 and +24 m above modern sea level are found spanning the northwest to the southeast boundaries of the archipelago. Flank margin caves are the primary remaining evidence of past sea-level position, because almost all mid-Pleistocene subtidal deposits, and related sea-level indicators such as subtidal facies, sea caves, and bioerosion notches, have been removed by karst denudation. Cave elevations up to 24 m (above sea level) indicate that prior assumptions as to the rate of subsidence of the Bahama Banks at 1–2 m per 100 ka may not be correct. The activity of MIS 5e was recent enough, and its subtidal deposits voluminous enough, to survive to the present, along with the majority of flank margin caves formed at that time. Karst denudation may have created sufficient mass loss that isostatic subsidence stopped, or was possibly reversed, as has been demonstrated for the Florida peninsula. If true, then mid-Pleistocene flank margin caves may not represent eustatic sea-level position at the time of speleogenesis.
TL;DR: Zheng et al. as discussed by the authors constructed an evaluation index system for marine technological innovation capabilities and marine ecological economic development in Fujian Province, and established a coupling model to calculate the coordinated development status and changing trend of marine technologies innovation ability and ecological economy.
Abstract: Wang, Y.; Deng, Q., and Zhang, Y., 2020. Research on the coupling and coordinated development of marine technological innovation and marine ecological economic development. In: Zheng, C.W.; Wang, Q.; Zhan, C., and Yang, S.B. (eds.), Air-Sea Interaction and Coastal Environments of the Maritime and Polar Silk Roads. Journal of Coastal Research, Special Issue No. 99, pp. 419–427. Coconut Creek (Florida), ISSN 0749-0208.The development of modern marine ecological economy relies heavily on scientific and technological progress. The level of development of marine scientific and technological innovation capabilities can to some extent reflect the level of marine ecological economic development in a certain region and future innovation directions and space. Fujian Province is selected as the research object to construct an evaluation index system for marine technological innovation capabilities and marine ecological economic development. Based on the sample of Fujian marine technological innovation capabilities and marine ecological economic data from 2007 to 2016, a coupling model is established to calculate the coupling coordinated development status and changing trend of marine technological innovation ability and ecological economy. The results show that the coordination of marine technological innovation and marine ecological economic development in Fujian has gradually improved in the past decade, marine technological innovation provides growth momentum for marine ecological economic development, marine ecological economic development provides basic guarantee for marine technological innovation. Through the joint development of the two, the coordination degree of the two is improved, and the healthy and sustainable development of marine economy is promoted.
TL;DR: Finkl et al. as discussed by the authors used the Biophysical cross-shore classification system (BCCS) to create shore-parallel situational zonation mapping units, which can be parameterized in terms of alongshore breadth and depth below or elevation above sea level.
Abstract: Finkl, C.W. and Makowski, C., 2020. Lateral extrapolation of coastal catenary sequences using the Biophysical Cross-shore Classification System (BCCS) to create shore-parallel situational zonation mapping units. Journal of Coastal Research, 36(3), 457–471. Coconut Creek (Florida), ISSN 0749-0208.The Biophysical Cross-shore Classification System (BCCS), which uses transects to assess shore-normal ecological and geomorphological successions from offshore to onshore within a coastal belt (Finkl and Makowski, 2020a), also provides a basis for extrapolating cross-shore catenas into shore-parallel units. This paper shows that three-dimensional transects can be parameterized in terms of alongshore breadth as well as cross-shore width and depth below or elevation above sea level. The codification of cross-shore environments and habitats in the framework of the BCCS provides an interpretative basis for determining the lateral extent of transect units (archetypes and sub archetypes) by lateral extrapolation to polygonal mapping units. The method discussed here is akin to geological cores or cross-sections that are used to laterally extrapolate units within vertical sequences. Repetitive successions of archetypes, based on cross-shore ecological interpretation of satellite imagery, results in a common master sequence referred to as a Dominant Catenary Sequence (DCS). The DCS is composed of generic archetypes, such as Barrier, Beach, Beach Ridge, Cliff, Coral Reef, Delta, Dune, Flat, Ice, Lagoon, Mountain, Rock, Till (Glacial Material), Upland, and Wetland. The more detailed Coastal Ecological Sequence (CES) of a coastal belt, which is defined by a discrete codification sequence built up from the DCS, is formulated by cognitive geovisual analytics to link the dominant catena with a numbered shore-parallel shape distinction and subscripted sub archetypes to refine the sequential composite archetypes in a DCS. Once the DCS- or CES-labeled transect has been plotted on a satellite image, the identified shore-normal units can be extrapolated into shore-parallel polygons by traditional (i.e. visual, cognitive) image interpretive and mapping techniques to show the spatial extent of classified archetypes and sub archetypes.
TL;DR: Talavera et al. as mentioned in this paper used two UAV-based high-resolution record of the response of a seminatural sandy spit to a severe storm, which revealed a nonuniform coastal response between both sectors.
Abstract: Talavera, L.; del Rio, L.; and Benavente, J., 2020. UAS-based high-resolution record of the response of a seminatural sandy spit to a severe storm. In: Malvarez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 679-683. Coconut Creek (Florida), ISSN 0749-0208. Human infrastructures in barrier islands restrict the natural storm-induced overwash needed by these systems to evolve, further increasing their vulnerability in the medium and long term. For this reason, accurate overwash measurements in coastal environments subject to varying degrees of occupation are needed. In this work, two Unmanned Aerial System (UAS) flights were performed over two distinct sectors of a sandy spit located in Cadiz (SW Spain) prior and after the landfall of storm Emma. This storm was a high-energy event that lasted 153 hours,with an average significant wave height of 4 m and a storm peak of 6.81 m., and water levels (tide and surge) of up to 4 m. The images derived from the UAS flights were processed with Structure From Motion (SfM) algorithms using Pix4D software, resulting in high-resolution mosaics and Digital Elevation Models (DEMs) of the study area. These allowed (1) the digitization of the washover deposits in both sectors before and after the storm, and (2) the computation of DEMs of Difference (DoDs), which in turn allowed the analysis of volumetric estimates of erosion/accretion triggered by the significant overwash. The results revealed a nonuniform coastal response between both sectors. The area subject to higher degree of development showed a clear restriction in the onshore delivery of sediment during overwash due to the presence of a channel and a road, the coalescence of the nine pre-existing washovers into a unique deposit of 77546 m2, and much higher damage extents and associated recovery costs. In the natural sector, the overwash processes reactivated the three pre-existing washovers (which enlarged their areas up to 200%) with no significant damages reported. These findings serve as examples of coastal responses to future similar hydrodynamic conditions, and suggest that this spit will likely evolve following different trajectories in the long-term.
TL;DR: Ogorodov et al. as discussed by the authors presented an overview of 16 sites of coastal erosion monitoring at the fastest retreating key sites across the Russian Arctic, making them very sensitive to sea ice reduction and ice-free period increase along with the temperature growth.
Abstract: Ogorodov S.A., Aleksyutita D.M. et al., 2020. Coastal erosion of the Russian Arctic: An overview. In: Malvarez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 599-604. Coconut Creek (Florida), ISSN 0749-0208.An overview of 16 sites of coastal erosion monitoring at the fastest retreating key sites across the Russian Arctic was made. All of these coasts are composed by permafrost, creating specific conditions of their evolution and making them very sensitive to sea ice reduction and ice-free period increase along with the temperature growth, resulting from the ongoing climate change. Erosion of permafrost coasts is among the fastest destructive geomorphic processes in the Arctic. For each key area, data from literature on sediment composition, coastal morphology, permafrost properties and climate evolution were collected, assessed and compared. Rates of coastal retreat in the XX-XXI century derived from direct field measurements and processing of remotely sensed data were analyzed; mechanisms and drivers of coastal erosion were estimated. Patterns of spatial variability and temporal evolution of the coasts were suggested. The influence of different factors of coastal dynamics on thermodenudation (destruction of the bluffs during thawing of permafrost and ground ice) and thermoabrasion (erosion resulting from direct contact of waves with the frozen bluff) was estimated.
TL;DR: An evaluation system of cross-border logistics marine transportation efficiency is constructed with port efficiency, port throughput, marine vessel efficiency, ocean port cooperation as the main level indicators, and it is applied to the empirical analysis of five representative ports in China.
Abstract: Li, X.P.; Zhao, X.Y., and Bai, D.L., 2020. Marine transport efficiency evaluation of cross-border logistics based on AHP-TOPSIS method. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 95–99. Coconut Creek (Florida), ISSN 0749-0208.Ocean transportation is one of the main means of cross-border logistics transportation. There are many factors that affect ocean transportation. How to find out the main factors is the key to improve the efficiency of cross-border logistics ocean transportation. Based on the AHP—TOPSIS method, an evaluation system of cross-border logistics marine transportation efficiency is constructed with port efficiency, port throughput, marine vessel efficiency, ocean port cooperation as the main level indicators, and it is applied to the empirical analysis of five representative ports in China, namely Dalian port, Tianjin port, Qingdao port, Shanghai Port and Guangzhou port. The results show that Shanghai port has the highest marine transportation efficiency. At the same time. Port handling and communication efficiency is the main factor affecting the efficiency of marine transportation.
TL;DR: Gopalakrishnan et al. as mentioned in this paper made an attempt to estimate the extent of land and paddy fields area that will be potentially inundated by 2050 and 2100 on the basis of different Intergovernmental Panel on Climate Change Representative Concentration Pathway (RCP) scenarios.
Abstract: Gopalakrishnan, T. and Kumar, L., 2020. Potential impacts of sea-level rise upon the Jaffna Peninsula, Sri Lanka: How climate change can adversely affect the coastal zone. Journal of Coastal Research, 36(5), 951–960. Coconut Creek (Florida), ISSN 0749-0208.Sea-level rise (SLR) is anticipated to be one of the most crucial factors putting pressure on the livelihood of human life in the 21st century. The Jaffna Peninsula, located at the northern tip of Sri Lanka, is no exception. This area lies entirely within 10 km of the coast and has an almost flat topography with a maximum elevation of 15 m above mean sea level (a.s.l.), whereas 50% of the total land area is less than 2 m a.s.l., making it highly vulnerable to coastal hazards, including SLR. An attempt was made to estimate the extent of land and paddy fields area that will be potentially inundated by 2050 and 2100 on the basis of different Intergovernmental Panel on Climate Change Representative Concentration Pathway (RCP) scenarios. Across four SLR scenarios, the total land area of the Jaffna Peninsula that will be directly inundated by 2050 is 6.8–13% and by 2100 this value will rise to 10–35%. Moreover, the Jaffna Peninsula is projected to lose approximately 7193–13,595 ha of paddy fields by 2050 and 10,630–36,786 ha by 2100. Considering the uncertainty in the inundation model, the total land area that could be under risk of inundation is 46.3% and 49.1% by 2050 and 2100, respectively, under the low-end scenario (RCP2.6), and 47% and 58.5% under the high-end scenario (RCP8.5). The areas surrounding the lagoons and the adjacent islands are identified as being the most vulnerable to SLR. The scale of the anticipated inundation on land and paddy fields underscores the urgent need for action to ensure the sustainable livelihoods of the region's population.
