Abstract:
Coastal regions of Ghana are primarily engaged in sea and lagoon fishing. Like many lagoons in Ghana, Fosu lagoon is a major source of livelihood for its surrounding communities. However, the lagoon and its associated marsh vegetation is under serious threat from human-induced interference. Due to this, the lagoon is considered as one of the most polluted lagoons in Ghana. Also, studies reveal that a major conservation challenge is the lack of inventory for the lagoon’s associated vegetation. Hence, the research was to map and assess the lagoon’s habitat and identify threats to the lagoon. In achieving the research objectives, remote sensing and GIS technique were used to effectively map the lagoon and the catchment area. The result indicated that the Fosu lagoon is characterized by a massive decline in lagoon size and the vegetation cover. Thus, the standing water has declined by 50.2 acres from 1970 to 2017 to physical development and weeds. Also, it was evident in the result that the lagoon’s vegetation is now fragmented into six various vegetation types and the weeds in the lagoon make approximately one-third of the lagoon’s vegetation cover. Also, adding to the threat of the lagoon were high levels of plastic waste and metal pollution. Hence, if current trend continues, the possibility of further degradation is very high. The main impact of this research was to provide evidence to the gradual disappearance of the Fosu lagoon.

Abstract:
Springs are common features on the Yucatán coast. They can discharge either under the sea (submarine) or inland in coastal lagoons and wetlands. Previous observations of a coastal lagoon located on the northern Yucatán Peninsula (La Carbonera) reported sea water intrusion on a spring that discharge on a coastal lagoon (lagoon tidal spring). The saltwater intrusion occurs when the tide is at its lower level, which is the opposite to what has been reported for submarine springs in the Yucatán Peninsula. In this study, the hydrodynamics of the spring is analyzed and the driving forces controlling the seawater intrusion are identified and discussed. Time series of water levels, salinity, and velocity measurements in the lagoon, the aquifer, and the spring are analyzed by means of tide component decomposition and cross-correlations analysis of the tide signals. Results show that the main driving forces causing the intrusion are the density differences and pressure head gradients, and the mechanisms influencing the driving forces driving those differences are the tides, the friction in the lagoon, and the confinement of the aquifer; other mechanisms are discussed to present a complete idea of the complexity of the interactions between the coastal aquifer, the coastal lagoons, and the sea.

Abstract:
Of the 14 inlets belonging to 12 coastal lagoons in the coastal zone of Central Vietnam, the unstable group consists of 4 inlets; the less stable group comprises 4 inlets and the relatively stable group has 6 inlets. For the feasibility and effectiveness, the constructions of stabilizing lagoonal inlets must be multi-purpose and multi-benefit, such as maintenance of ecosystems, opening to the sea for ships and boats, flood drainage and pollution limitation. They need to be combined with other development activities to reduce costs and increase benefits, for example in conjunction with seaports, fishing harbours, typhoon shelters and tourism... Solutions to stabilise the lagoonal inlets consist of 5 groups: Constructing groins for control of inlets; dredging lagoonal inlets and bottom; preventing coastal erosion outside the lagoons; stabilizing the lagoon banks and the surrounding sandy areas; regulating water supplies in the catchments into the lagoons. Depending on the natural conditions and degrees of human impact, the priority solution has been proposed for each lagoonal inlet.

Abstract:
We studied the cultural eutrophication process assessments of coastal lagoons by considering sociopolitical, socioeconomic, demographic, technological, and cultural factors, which represent indirect drivers exerting effects on the eutrophication process, causing changes on the trophic status. Multifactorial interactions in eutrophication processes make understanding their complex dynamics difficult, leading to unreliable assessments and, consequently, to unsustainable management actions. This, in turn, hinders the feasibility of coastal lagoon sustainability. We propose a method based on the evaluation of pathways derived from a multifactorial network, which represents the eutrophication process, with the aim of determining the feasibility of the sustainability of the Tres Palos coastal lagoon. Our findings revealed that most of the evaluations of relationships belonging to pathways were unfeasible due to reasons such as: there was no evidence of the existence of public policies, technological skills, and cultural factors; there was a lack of data related to human settlements around the lagoon and river, industrial waste, agricultural practices, and tourism. The preceding shortcomings hinder the feasibility of coastal lagoon sustainability under study. We suggest that assessments of cultural eutrophication processes that overlook sociopolitical, socioeconomic, technological, and cultural factors are limited and inadequate for supporting the feasibility of sustainable coastal lagoons.

Abstract:
Coastal lagoons are highly variable environments that may act as hotspots of genetic diversity as a consequence of their ecological role as nursery habitats of marine species with both ecological and fisheries importance. The edible cockle (Cerastoderma edule) is a commercially important shellfish resource inhabiting coastal lagoons in Europe and their fisheries management urgently needs genetic studies to design appropriate strategies to promote the recovery of exploited populations. The aim of this study was to assess the C. edule genetic diversity and population structure at a small geographic scale, inside Ria Formosa coastal lagoon (southern Portugal) using mitochondrial cytochrome oxidase I sequences in six locations. Outcomes pointed to a common pattern of high haplotype diversity and non-significant genetic structuring inside the Ria Formosa lagoon. A high level of gene flow was detected between all localities and the presence of a single stock from a genetic point of view may be considered for fisheries management purposes. The existence of a high number of haplotypes and high values of haplotype diversity of C. edule in Ria Formosa lagoon could be consistent with the hypothesis that higher genetic diversity is expected in populations occurring in coastal lagoons, suggesting that lagoons could increase standing genetic variation and an adaptive potential of lagoon populations as an ecological response to a highly variable environment.

Abstract:
Restingas are coastal ecosystems associated with the Atlantic Forest. They are threatened by habitat degradation and forest fragmentation due to intense human occupation. Many restingas have coastal lagoons formed by bay sedimentation of bays, the presence of river estuaries, or emerging groundwater. The distance between lagoons and the ocean influences the biotic community in them. This study aimed to compare the diversity (composition, abundance and richness) of bat communities associated with three lagoons within the Paulo Cesar Vinha State Park, Espírito Santo state. Two lagoons (‘Feia’ and ‘Vermelha’ lagoons) are 2 km away from the ocean, while the third (‘Caraís’ lagoon) is just a few meters distant from the ocean. Species composition did not differ among the lagoons. Abundance of Carollia perspicillata and Glossophaga soricina was higher in the ‘Caraís’ lagoon. Abundance of Artibeus lituratus and Platyrrhinus lineatus was higher in the ‘Vermelha’ lagoon. Species with higher abundance in the ‘Vermelha’ are usually associated with urban and disturbed environments. ‘Vermelha’ lagoon is closer to human settlements and this could be a major driver of bat species abundance associated with this lagoon instead of distance from the ocean. These results may be used to guide conservations efforts in the restingas or habitats associated with restingas.

Abstract:
Abstract Submerged aquatic vegetation (SAV) is considered as a keystone habitat, contributing significantly to structure and function of coastal lagoons. However, limited understanding of the factors driving SAV distribution and abundance across a wide range of salinity in tropical coastal lagoons has restricted the effectiveness of managing and preserving the ecosystem services in coastal lagoon habitats. This study examined the distribution and abundance of SAV species in the growing season in relation to water physico-chemical variables and grain sizes of sediment types in a tropical lagoon in Viet Nam. The results revealed that Najas indica and Halophila beccarii were the dominant species in the community of 7 SAV species, accounting for 70% of the total cover and 55% of the total biomass sampled. Variation partitioning showed that both water and sediment variables were important in explaining spatial distribution and abundance of SAV species across the coastal lagoon. Salinity was the most significant predictor variable that accounted for the variation of SAV species data. The study implied that changes of salinity and silt (versus sand) particles can lead to different SAV assemblages in the lagoon.

Abstract:
This paper presents a biogeochemical model of a coastal lagoon intended to be representative of lagoons occurring along the south-east and south-west coasts of Australia. Many of these lagoons are threatened by increased nutrient loads because of land use change, by alterations to their freshwater inflows and by modification to their tidal flushing regimens. The model simulates the biogeochemical response of the lagoon to nutrient (nitrogen) loading and includes nutrient transformation processes in the sediments, as well as in the water column. The paper focuses on the response of primary producers to increasing and decreasing nutrient loads and how the response is altered by changes in the flushing rate of the lagoon with the sea. In common with lakes, the modelled lagoon exhibits alternative stable states representing macrophyte or phytoplankton dominance depending on nutrient loading and history. A third state representing severe degradation occurs when denitrification shuts down. A characteristic of Australian coastal lagoon systems is that, due to highly sporadic rainfall patterns, nutrient inflows are dominated by intermittent extreme events. The modelling demonstrates that such a loading regimen may be expected to generally increase the vulnerability of the lagoon to increasing nutrient loads. The results of the analysis presented are pertinent to several questions raised by coastal managers, such as what are the expected benefits of improving flushing by dredging and what are the consequences of altering the timing and magnitudes of the loads reaching the lagoons?

Abstract:
Small Arctic coastal catchments and coastal lagoon systems are some of the most vulnerable to climate change. Glacial retreat and the development of glacial lakes and drainage systems provide opportunities for hazardous events such as GLOFs. We observe that the stability of lagoons and their associated barriers are controlled by the frequency and magnitude of storms approaching the coasts, access to sediment supplies and resilience to sea-level rise. Based on multidecadal remote sensing data, we were able to identify the rate of glacial recession, the development of glacial lakes, vegetation response to climate change and a GLOF event, and shoreline and lagoon responses to the environmental shifts within the small catchment. Here we present an example of lagoon system evolution where a glacial outburst flood exerted significant control over lagoon drainage and coastal barrier stability.

Abstract:
A coastal lagoon is a landform that is influenced by natural processes and human activities. All human activities at the upstream, particularly agriculture and cultivation bring soil, waste, and other materials to the downstream area through the river drains into the lagoon. Even though its position is inland of water bodies, the lagoon is still affected by waves and winds from the sea. Additionally, coastal lagoon will be the depository place for sedimentation from the upland area. Segara Anakan (SA), which is located in Indonesia, is an example of a coastal lagoon area, which has a unique biophysical characteristic. The region has a great natural ability to ensure the sustainability of the interrelationships between terrestrial, estuarine and marine ecosystems in harmony and balance as a habitat for flora and fauna. The region is an area of migration of various types of protected animals and it is a place of breeding for diverse species of the shrimp and fish, which have a highly economical value. Segara Anakan lagoon (SAL), currently experiencing acceleration narrowed on its area due to a very intensive sedimentation from the mainland. The research aims to answer the question of how ecological dynamic occurs in the SAL area due to sedimentation. Achieving the objectives of this study required examining the morphology and land use changes with multitemporal remote sensing approaches. While, to assess the role of community participation and planning management strategies is using qualitative descriptive methods and SWOT analyze. The using of multitemporal remote sensing Landsat images is possible to analyze the morphological and land use changes with different time and sensors. These Landsat has image accuracy about 92.66%. It can be used for image interpretations resulting 13 classes of land use. The morphodynamics of SAL indicated by the changes of area of lagoon and accreted land and also the distance of coastlines during the periods 1979-2013. In addition, the land use or land cover also changes during that time. The bigger portions of land use changes are in the tropical and mangrove\'s forests. There are distinctive forms of participation in conservation efforts. The upstream community involvement in conservation tends to be different participating in the way of ideas, money, materials, properties, skills and expertise or social activities. In addition, the community at downstream area has a sufficiently high level of participation in environmental conservation. There are also strong relationships between the level of education and level of income and basic knowledge in conservation with the participation of SA conservation. The ecological dynamics of the SAL area are described with a historical time line. It is divided into three time periods: the 1970s - 1980s, the 1990s and from 2000 onwards. Each of these has occurrences that can lead to changes in the environment. The implementation of appropriate conservation technique can reduce the sedimentation rate. Hence, the synergic coordination measures between upstream and downstream regions are necessary in the future. Increasing community awareness and participation in the conservation by improving educational sector, providing information, and applying sustainable development land use are the ways to match human activities with the temporal and spatial dynamics of the coastal resources.

Abstract:
The Patos Lagoon, the largest choked coastal lagoon in the world, is a typical centre of population, commerce, industry and recreation, and consequently it is also a site for disposal of industrial, agricultural and municipal wastes. Important questions concerning beneficial uses of and potential changes to the lagoon and its estuary are left unanswered without a good understanding of hydrodynamic processes. The current study involves the choice, calibration and application of a numerical model which can be used in future hydrodynamic, sediment transport and water quality studies in the area. The two- and three-dimensional modes of the TELEMAC System were chosen to study the hydrodynamics of the Patos Lagoon. In order to calibrate the TELEMAC-2D model for the lagoon, measurements of salinity, current speed and direction, water elevation and wind speed and direction were carried out simultaneously at three stations in the estuarine area during three days. The model validation was carried out against an independent data set from the 1998 El Nino event. Several two-dimensional simulations were carried out to investigate the main processes controlling the Patos Lagoon hydrodynamics. The model was forced with prescribed river inflow at the top of the lagoon, wind stress at the surface and water elevation at the ocean boundary. The barotropic pressure gradients established between the lagoon and the coastal area as a result of local and remote wind combined with the freshwater discharge, proved to be the main forces controlling the lagoon subtidal circulation, as well as the exchanges between the lagoon and the coast. The local wind dominates the lagoon circulation through the set-up/set-down mechanism of oscillation, whereas the non-local wind drives the circulation in the lower estuary. The entrance channel acts as a filter and strongly reduces tidal and subtidal oscillations generated offshore. Three-dimensional simulations proved to be essential. Studies of the processes involved in the estuarine transverse circulation showed that the wind drives the lateral flow in the shallow areas, whereas in the channel it depends on lateral pressure gradients and channel curvature and geometry. Insights on the estuarine baroclinic circulation indicate the barotropic forces as the main mechanism controlling salt water penetration and salinity structure in the estuary. This study produced valuable information into the forces controlling the circulation of the Patos Lagoon and its estuary. Important issues regarding the capabilities of the TELEMAC System twoand three-dimensional modules were explored, producing a valuable tool for further hydrodynamic and sediment transport numerical modelling experiments.

Abstract:
The Ria Formosa is a lagoon on the South coast of the Algarve, Portugal and insulates SS km of the coastline from the full impact of the Atlantic. A review of the lagoon considers its geomorphology, sedimentology, hydrography, water quality and ecology. The Ria Formosa is identified as an important regional and national resource with respect to recreation, tourism, fishing, aquaculture, shipping and salt extraction. Ma*or regional developments in the form of spreading urbanisation and intensified agriculture, together with rising numbers in both the resident population and the annual tourist influx, pose an ever increasing stress upon the lagoon system, particularly with respect to water quality. The region contiguous to the lagoon is devoid of heavy industries and the review concludes that the greatest threat to sustained development of the lagoon resources is a progressive deterioration of water quality promoted by ever increasing discharges of nutrient and organic rich sewage effluent. In consequence, this study of the water quality in the Ria Formosa focuses upon the spatial and temporal variability in the nutrient and dissolved oxygen fields. Hydrographic, nutrient and dissolved oxygen data captured during three separate sampfing programmes are presented and discussed. The first programme addressed the variability in the lagoon as a whole. From June 1987 to May 1988 hydrographic, nutrient and dissolved oxygen data were collected at monthly intervals from sixteen sampling stations distributed through the lagoon. All sampling events were coincident with high and low water on neap tides. This sequence of surveys showed that during the winter the lagoon acts as a typical estuary but for several months during the hot, dry summer the salinity of the waters within the lagoon exceeds that of the seaward boundary. No evidence of either marked or persistent stratification was found. Despite strong tidal flushing, the waters within the lagoon are not homogenous and the characteristics of the incoming coastal water are significantly modified in the inner reaches. Principal Component Analysis divided the sixteen sampling stations into four groups: (i) stations in the outer lagoon where water characteristics are little modified by the inner lagoon processes and sources; (ii) intermediate stations with water characteristics dominated by the inflowing seawater 11 but somewhat modified by inner lagoon processes and/or sources; (iii) estuarine stations where the water properties are greatly influenced by freshwater inputs; (iv) inner lagoon stations insufficiently flushed by tidal exchange and partly influenced by inner lagoon processes and sources. Stations comprising the latter group (in the vicinity of the city of Faro, the West end and the East end of the lagoon) all exhibited characteristics symptomatic of a marked reduction in water quality. These were manifest to a greater extent at the station adjacent to Faro. A comparison of the range of nutrient concentrations in the Ria Formosa with other lagoon systems identifies it as being one of the most nutrient enriched. It is concluded, however, that good water quality prevails throughout most of the lagoon at all times of the year and that the presence of, or potential for, adverse water quality is localised in particular areas. The objective of the second sampling programme was to generate a temporal record of the extent to which the properties of the coastal waters entering the lagoon were modified in the western inner reaches of the lagoon. Samples were taken weekly on Springs and Neap tides throughout 1989 coincident with high water at the coastal station and at low water in the lagoon. The offshore water showed a strong seasonal signal with an abrupt change of water type in autumn. Throughout the year, the lagoon water was consistently and significantly enriched in silicate relative to the seawater, but also with respect to ammonium and nitrite in winter. In contrast there was no evidence of an internal source of nitrate. Almost half of the morning samples showed the lagoon water to be less than 80% saturated in dissolved oxygen on most occasions during the summer months. Hypersaturation in summer afternoon samples exceeded the range recommended by European Union directives for water quality. The third sampling programme addressed short term variability of water characteristics at the western end of the lagoon. Observations every thirty minutes during the Extreme Spring Tide cycle of the autumn equinox showed that water from other parts of the lagoon (sewage contaminated water and water flushed off salt marshes) was flushed past the station during a tidal cycle. Percentage saturations of dissolved oxygen reached an early morning minimum of 54%. The nutrient and III dissolved oxygen observations indicated that the water quality situation in the western part of the lagoon was precarious. A set of circumstances which would provoke mass mortality of the biota under the conditions at the time of the study is outlined. The conditions in the Ria Formosa were compared to other lagoons and it was concluded that the Ria Formosa is relatively nutrient rich.

Abstract:
Coastal wetlands and rivermouth lagoons are dynamic systems, which respond rapidly to sea-level, tectonic, meteorological, anthropogenic and other synergistic drivers. This research used a multi-disciplinary approach to investigate two representative West Coast lagoon systems (Totara Lagoon and the Shearer Swamp-Waikoriri Lagoon Complex) in order to document their present-day geomorphology and determine the development and processes acting on these systems over historical time. This information was then used to predict their future under varying climate, development and management pressures. In addition to adding to the West Coast knowledge base, the findings of this research are applicable to similar systems elsewhere in New Zealand and internationally. This investigation used a multidisciplinary approach to investigate the dynamics, structure, development and active processes in the two study systems. Techniques to document current hydrology and topography included hydrological records of water level, temperature and conductivity, and Global Navigation Satellite Surveys (GNSS). Outlet dynamics over a decadal scale were investigated through temporal aerial photograph analysis, and sediment core analyses showed changes occurring over longer timescales. Significant differences in morphology and dynamics were observed between Totara Lagoon and Waikoriri Lagoon, with the former being much larger, more stable, and less dynamic in terms of dune morphology and outlet migratory patterns. Hydrologically, Totara Lagoon is currently in an estuarine phase, and experiences significant tidal inflows, which demonstrates the connectivity between definitions of coastal lagoons and estuaries. Waikoriri Lagoon is freshwater, and can be described as a hapua-type system, but exhibits very different river flow and barrier composition to East Coast examples. Sediment core analyses from Shearer Swamp and northern Totara Lagoon showed little change over a decadal to centennial scale, but evidence of a change in margin dynamics in response to farming and stabilisation of adjacent dune ridges was observed in Shearer Swamp. Results suggest landward migration of the southern end of Totara Lagoon occurred over this timeframe. The future of these systems depends on the interaction between climate and anthropogenic (including management) factors. A conceptual model of process and response suggests three possible resultant scenarios: lagoon loss, natural lagoon, or artificially modified lagoon. A significant finding of this research is the recognition that some systems exist on a continuum between a hapua and an estuary, switching hydrological states through time while maintaining consistent morphology. In addition, the importance of barrier permeability in hapua formation is highlighted, and the term ‘sandy hapua’ introduced to distinguish these low-flow systems with low barrier permeability from the typical mixed sand and gravel examples documented on the East Coast. These findings enhance scientific understanding of rivermouth lagoon systems, and demonstrate the wide spectrum of conditions under which they may form. This process-based understanding is important from a coastal management perspective as concerns of human induced climate change and accelerated sea level rise grow.

Abstract:
Evidence of Holocene sea-level changes along the Rio de Janeiro State Coast, and for the evolution of coastal lagoons and barriers in response to these sea- level movements, has been examined using stratigraphical and micropalaeontological techniques, radiocarbon dating and published data. Present-day diatom death assemblages have been studied in order to facilitate the interpretation of fossil assemblages, which has inter aha permitted the development of a simple statistical technique for the evaluation of the allochthonous diatom component. Modern lagoonal tide- gauge data have been used to establish a relationship between lagoonal water levels and tidal levels on the open coast. Evidence is presented which indicates that barriers which were previously believed to date from the mid-Holocene formed during the 'Last' Interglacial. The history of true Holocene barriers has been shown to be relatively complex, with some barriers having migrated by over-stepping and others by continous shoreface retreat. The published Holocene sea-level maximum for Rio de Janeiro State of -t- 4.8 m at 5100 BP is considered to be in error (approximately 3.0 m too high at this time) and a maximum Holocene sea level of -t- 3.0 m at c. 4000 BP is preferred. The evidence for sea-level maxima in other parts of Brazil at 5150 BP and for the migration of the geoid surface during the Holocene is questioned and shown to require further study. It is tentatively suggested that there may be evidence for an interglacial sea-level high at c. 35000 BP in Rio de Janeiro State.

In-depth studies have been carried out at Lake Miragoane, Haiti and in high- and mid-elevation sites in the Dominican Republic, and a few other inland and coastal locations throughout the Caribbean; however, to date little has been published on prehistoric conditions in other coastal areas of Hispaniola. Laguna Alejandro (informally named by researchers) (~18.31°N, 71.03°W), on the southwest coast of the Dominican Republic, was examined to expand our knowledge of long-term environmental history in this region. This ~25 hectare lake is separated from the Caribbean Sea by a 100 m wide limestone ridge about 3â 5 m tall. We recovered two consecutive cores (0â 100 cm, 100â 185.5 cm) close to the limestone barrier to investigate the potential for paleotempestology and other paleoenvironmental reconstructions. Three AMS 14C dates indicate that the lake is ~1100 years in age. Sediment analyses revealed three major events that correlate with bands of uncharacteristic sediment composition and particle size at 74â 77.5 cm, 150.5â 153 cm, and 183.5â 185.5 cm. Four distinct strata containing serpulids and several pockets of Ammonia beccarii provided insights on changes in salinity and the connections between the lagoon and the ocean. The upper deposit (74â 77.5 cm, 620 ±60 YBP) contains gypsum and represents a period of increased salinity within the lake brought on by drought. The two lower bands are composed of sand consistent with nearby beach sands. The 150.5â 153 cm band provides evidence of a hurricane landfall at 1022 ± 60 YBP. The combination of biological data from 165â 183.5 cm and sediments within the 183.5â 185.5 cm band provide evidence for salinity fluctuations that indicate the closure of the lake. Sediments contained a variety of invertebrates that helped to document changes in lake chemistry through time. This study of Laguna Alejandro sediments documented lake history and provided information on recent climatic shifts in the region.

Abstract:
Tsunamis are low amplitude, large wavelength waves that can significantly impact coastal regions. Although their destructive impacts are clear from recent events, the frequency with which tsunamis occur is less well constrained. To better understand the tsunami history and coastal impacts in Sri Lanka, this study compares sediments deposited by the December 26, 2004, tsunami to older lagoon sediments in search of evidence for paleotsunami deposits. Results from this study illustrate that the coastal lagoons in Sri Lanka preserve tsunami deposits and can provide the first steps towards constraining the paleotsunami history of the Indian Ocean. Because Sri Lanka is a far field location relative to the Sumatra-Andaman subduction zone, the preserved tsunami deposits are likely mega-tsunami events similar in size and destruction to the December 26, 2004, tsunami. The December 26, 2004, M 9.1?9.3 Sumatra-Andaman earthquake generated a massive tsunami that propagated throughout the Indian Ocean, causing extreme coastal inundation and destruction. The southeastern coastline of Sri Lanka was impacted by the 2004 tsunami where between one and three waves inundated coastal villages, lagoons, and lowlands, killing more than 35,000 people. Karagan Lagoon, located on the southeastern coast of Sri Lanka, was impacted by two waves from this tsunami. Although the lagoon commonly is dominated by organic-rich, siliciclastic clays, silts, and fine sands, the 2004 tsunami deposited a distinct layer of coarse quartz-dominated sand between 1 and 22 cm thick. The base of the 2004 deposit is sharp and erosional and some layers feature faint subparallel laminations. The 2004 tsunami deposit is generally continuous, fines landward, and is confined to the eastern portion of Karagan Lagoon, in the direction from which the tsunami arrived. Sri Lankan lore, in conjunction with reconstructed historical earthquake data, suggests that other tsunamis likely affected Sri Lanka in the past. To test this, twenty-two 1?4 m sediment cores were collected from Karagan Lagoon, providing key information for unraveling the pre-2004 tsunami history of southeastern Sri Lanka. At depth, sixteen cores from Karagan Lagoon contain as many as ten distinct sand layers, including the deposit from the 2004 tsunami. These cores feature siliciclastic clays, silts, and fine sands that dominate the background lagoonal sedimentation that are punctuated by coarse sand layers. These sand-rich layers feature sharp, erosional bases, coarsen and fine upwards, vary in thickness from 1 to 22 cm, and include varying percentages of fine to very coarse sand, with a low-abundance of silt and clay. In the best constrained interval, three coarse sand layers include composition, grain size, grading, and sedimentary structures similar to the sediments deposited by the December 26, 2004, tsunami. The layers are identified in five of the twenty-two cores, although the thicknesses vary. Six additional less well constrained sand layers are present in four of the twenty-two cores. Cores located closer to the lagoon mouth and the eastern coastline (the direction from which the 2004 tsunami arrived) contain more sand layers than cores farther away from the tsunami wave entry point. On the basis of their sedimentary structures, geometry, and extent, these sandy layers are interpreted to represent paleotsunami deposits. AMS radiocarbon dating was used to date the bulk organic sediment from above, between, and below the ten paleotsunami layers in sediment cores from Karagan Lagoon to constrain the timing of events in southeastern Sri Lanka. Material from within the deposit was not dated because it was likely transported from various sources during the event and thus does not represent the age of the tsunami. AMS radiocarbon dates from above and below the paleotsunami layers were calibrated from radiocarbon years before present to calendar years before present (Cal YBP) using OxCal v. 4.0 (Bronk Ramsey, 1995; Bronk Ramsey, 2001) with calibration curve IntCal04 (Reimer et al., 2004). The constraining time intervals of tsunami deposits II?VI were averaged to yield deposits of ages 226, 1641, 4198, 4457, 4924 Cal YBP. Tsunamis VII?X only had sediment dated immediately below the deposit and therefore were deposited prior to 6249, 6455, 6665, and 6840 Cal YBP. In total, ten tsunami deposits, including the 2004 event, are preserved in Karagan Lagoon on the southeastern coast of Sri Lanka. The Karagan Lagoon paleotsunami deposits provide constraints on the recurrence interval of tsunamis similar in magnitude to the 2004 event. The uppermost paleotsunami units were deposited 226, 1641, 4198, 4457, and 4924 Cal YBP, based on AMS radiocarbon dating. Thus, including the 2004 event, six tsunamis affected Karagan Lagoon in the past 5500 years, yielding a recurrence interval of approximately 916 years. Three of the six events, however, occur between ~4000 and 5500 years yielding a recurrence interval of approximately 500 years for this 1500 year period. Four additional older paleotsunami deposits occur in the deeper sections of the cores and were deposited prior to 6249, 6455, 6665, and 6840 Cal YBP, yielding a recurrence interval of approximately 200 years for this time period. Assuming that Karagan Lagoon contains a complete record of tsunami events, the recurrence of tsunamis similar in magnitude to the December 26, 2004, event can occur as often as 200 years. This ?recurrence interval? is illustrated by our data for the time period with increased tsunami activity from ~4000 to 7000 Cal YBP. Tsunamis may potentially affect Sri Lanka at relatively high frequency during certain time intervals though the overall recurrence pattern of these events displays a highly irregular distribution. This extreme variability needs to be taken into consideration when such events are related to earthquake recurrence intervals. Prior to the December 26, 2004, tsunami, paleotsunami deposits in the Indian Ocean were largely unstudied and consequently, Holocene tsunami chronology was incompletely understood for the Indian Ocean. The results from this study represents the first geologic evidence of paleotsunami deposits in Sri Lanka generated by tsunamis during the past 7000 years. The identification of these paleotsunami deposits illustrates that the 2004 tsunami was not a ?one-time event,? but in fact has ancient counterparts.

Abstract:
AbstractLagoons are a common feature of the low-lying West African coastline. These lagoons are resource-rich and biodiverse. The small-scale fishing communities, which border them, are dependent on the resources and ecosystem services for their livelihoods and well-being. Climate change has had significant and diverse effects on both the lagoons and their surrounding communities. Sea level rise has caused erosion of the coast and increased the risk of floods. Changes to rainfall patterns have caused shifts in lagoon ecosystems and physical cycles. Of particular relevance to lagoon fishing communities is the fluctuation in quantity and distribution of fish catch that they rely upon for economic livelihood. Understanding the vulnerability of these communities to the effects of climate change is critical to supporting and developing successful adaptations. Using a case study from Ghana, sustainable livelihoods approach (SLA) and vulnerability framework are used to characterize the community vulnerability, giving insight into the temporal and spatial dynamics of vulnerability and how subsections of the community may be identified and prioritized for adaptation interventions. A scalar analysis of the relevant coastal and environmental frameworks and policy to support climate change adaptation in coastal communities reveals the common challenges in implementing adaptation interventions and strategies in the region. A policy gap exists between high level, institutional coastal, and climate directives and implementation of climate adaptations at the local level. That gap might be bridged by a participatory approach that places coastal communities at the center of creating and enacting climate change adaptations.

Abstract:
Lagoons are one of the most vulnerable ecosystems to impacts of natural environmental and anthropogenic factors. The Curonian and Vistula Lagoons are one of the largest lagoons of Europe. The Curonian Lagoon is choke mostly freshwater, while the Vistula Lagoon is restricted brackish water. Hydrological, chemical and biological researches were carried out monthly since 1991 to 2014. Reductions of nutrients loading in 1990s did not result in improvement of the ecological situation. Hydrological and chemical parameters are the main factors that influence on the algal blooms and ecosystem health in these lagoons. The Curonian Lagoon may be characterized as hypertrophic water body with "poor" water quality. Climate change in 1990s-2010s combined with other factors (freshwater, slow-flow exchange, high nutrients concentrations) creates conditions for Cyanobacteria “hyperblooms”. Harmful algal blooms result in deterioration of the water chemical parameters and death of fish. "Hyperblooms" is the most dangerous for coastal towns and tourist resorts (UNESCO National Park "Curonian Spit"). Climate change in 1990s-2000s have been also observed in Vistula Lagoons (mean annual temperature increased by 1.4°C for 40 years), but brackish water prevent harmful algal hyperblooms. After the invasion of the filter-feeding mollusk Rangia water quality was significantly improved in 2011-2014, but ecosystem productivity remained at a stable long-term level.

Abstract:
Lagos faces increasingly severe annual flooding, exacerbated by sea level rise and subsidence. In 2021, floods again submerged vehicles and houses, displacing thousands from their homes. The demand for sand in construction materials drives illegal sand mining and erosion on the coast of Nigeria, degrading ecosystems and increasing flood risk. This technical background report for the 2021/2022 edition of the Interconnected Disaster Risks report analyses the root causes, drivers, impacts and potential solutions for the Lagos floods through a forensic analysis of academic literature, media articles and expert interviews.
