This research was conducted in June to July 2019. It aimed to analyze the vulnerability and the shoreline change of coastal area of Padang Pariaman Regency, West Sumatera Province. Survey methods with direct field observations were applied and different satellite imageries were also used to find out the shoreline change of coast under study. The results showed that there five categories of changes, namely high and low accretion (>2.1 m yr-1; 1 - 2 m yr-1); stable condition (-1 to 1 m yr-1); and high and low erosion (<-2 m yr-1; -1 to -2 m yr-1). Furthermore, the percentages of coastal vulnerability of the areas under study can be classified into five categories such as Very Low Condition (17.27 %), Low Condition (39.68 %), Medium Condition (29.02 %), High Condition (8.88 %), and Very High Condition (5,75 %). In addition, the districts of Sungai Limau and Batang Gasan had very high vulnerability conditions.

The coastal zones are highly resourceful and dynamic. In recent times, increased events of tropical cyclones and the devastating impact of the December 2004 tsunami have brought forth the importance of assessing the vulnerability of the coast to hazard-induced flooding and inundation in coastal areas. This study intends to develop coastal vulnerability index (CVI) for the administrative units, known astalukasof the Karnataka state. Seven physical and geologic risk variables characterizing the vulnerability of the coast, including rate of relative sea level change, historical shoreline change, coastal slope, coastal regional elevation, mean tidal range, and significant wave height derived using conventional and remotely sensed data, along with one socioeconomic parameter “population,” were used in the study. A total of 298 km of shoreline are ranked in the study. It was observed that about 68.65 km of the shoreline is under very high vulnerable category and 79.26 km of shoreline is under high vulnerable category. Of the remaining shoreline, 59.14 km and 91.04 km are of moderate and low vulnerable categories, respectively.

Abstract Fisheries has a major contribution for the Indonesian economy both on a local and national scale. However, the phenomenon of climate change can threaten the sustainability of this sector. Therefore, a scientific approach is needed to determine the level of risk and adaptation strategies for fisheries, one of which is through vulnerability analysis. Vulnerability is the final analysis resulted from the analysis of sensitivity and exposure. Both of these analyses are important to determine the parameters that will affect the value of the fishery vulnerability to climate change. This research is focused on sensitivity and exposure analysis with the coverage limit is the province area to determine the sensitivity and exposure index that exists in the study area. The result will be important input in further research for the vulnerability of capture fisheries to climate change. Three provinces in Indonesia were selected through purposive sampling method. The source of data for indices variables were using recorded data in 2009-2020 from relevant sources. Result described that SST variability in the three provinces has the same pattern. In the exposure analysis, the SST is linked to the catch resulting in different exposure statuses in each province. It also illustrated those areas with a very high number of fishermen and catches will have very high sensitivity. The research will support in the sustainable management of capture fish at the province scale.

Coastal vulnerability is a condition of a coastal community or society that leads to or causes an inability to face the threat of danger. The level of vulnerability can be viewed from the physical (infrastructure), social, demographic, and economic vulnerabilities. Physical vulnerability (infrastructure) describes a physical condition (infrastructure) that is prone to certain hazard factors. The coastal vulnerability areas can also be interpreted as a condition where there is an increase in the process of damage in the coastal area which is caused by various factors such as human activities and factors from the nature. This research aims to determine the level of coastal vulnerability in Indramayu coastal Regency with a Coastal Vulnerability Assessment (CVA) analysis approach and a Geographic Information System (GIS). Mapping the status of the vulnerability level of the Indramayu coastal area using the CVA method where the index range generated from the calculation of the four physical parameters mentioned above is between 2.887 – 3.651 or are in moderate vulnerability. A higher vulnerability value is found in several locations such as Juntikedokan and Benda villages. It is necessary to develop coastal protection in this area to prevent damage to the coastal area.

Animal species have evolved a remarkable diversity of defensive phenotypic strategies aimed to deceive predators and other forms of danger. By relying on deception, these adaptations increase the chances of avoiding physical contact that may otherwise have very high fitness costs. One such deceptive behaviour is the popularly-known neck flattening, or “hooding”, observed in some snakes. Hooding consists in the lateral expansion and dorso-ventral flattening of the neck, which creates the impression of a bigger opponent during confrontations. This trait is highly characteristic of cobras (Elapidae family). However, neck flattening is not exclusive to elapids, and has in fact been observed in a few other snake lineages, including some species of the families Lamprophiidae and Colubridae. Here, we present the first report of hooding behaviour in the South American colubrid genus Philodryas, based on field observations conducted on the Chilean species P. chamissonis (the long-tailed snake). Our report adds to the few cases in which this deceptive behaviour has been observed in snakes outside the cobra family.

The Impact

The Nile Delta is located on the Egyptian Mediterranean coast extending along nearly 240 km from the east of Alexandria to Port Said. The coastal area of the Nile Delta Promontories has been suffering extensive erosion problem. This was achieved after the construction of many water regulation structures in Nile River as dams and barrages, particularly the Aswan High Dam. It has nearly stopped the sediment flux carried by the Nile River to the Delta. This process has caused the Mediterranean Sea to reshape the Nile Delta coastal area. In order to cease these problems several engineering hard structures have been built. These structures avoided in ceasing the problem in the site of construction but shifted the erosion problem to the adjacent sites. This study aimed to analyze the shoreline change pattern on the term of three decades during the period between 1985 to 2015 at the coastal strip of Damietta Promontory and the impact of these protective structures on the coastal area. This was accomplished by the automated delineation of the successive shorelines covering this period using remote sensing imagery. The shorelines were extracted using the MNDWI index. The extracted shorelines were manipulated through the Digital Shoreline Analysis System (DSAS) software. The shoreline change rates were compared with sediments grain size for the past thirty years, heavy minerals content and radioactivity of recent marine sediment samples collected from different locations of marine profiles over the study area. The study revealed that Damietta Promontory has suffered from erosion during the study period reached its maximum shoreline retreat at the eastern side, nearly – 43 m/y. The total cumulative shoreline regression during the study period at this area was 1311m. The relation between the shoreline change process (erosion or accretion) and the physical parameters of coastal sediment showed that; as erosion increases, the heavy minerals content and radioactivity increases, while the mean grain size decreases and vice versa.

&lt;p&gt;Coastal hazards, including marine-related and gravity-induced processes such as landslides, coastal erosion, storm water runoff and coastal flooding, may have different impacts mainly due to local geomorphological characteristics and natural and anthropogenic settings. The sustainable conservation of coastal areas represents a worldwide issue and therefore, coastal vulnerability and risk assessments are of paramount importance for ensuring appropriate coastal management.&lt;/p&gt;&lt;p&gt;This study is focused on the assessment of coastal vulnerability along the NE sector of the Island of Gozo (Malta, Mediterranean Sea), which is characterized by diverse landforms, including plunging cliffs, sloping coasts, pocket beaches, shore platforms and a large sandy beach partly backed by dunes. Results of detailed geomorphological investigation, integrated with the analysis of marine geophysical data, show that the study area is particularly susceptible to mass movements, coastal flooding and erosion processes.&lt;/p&gt;&lt;p&gt;From the economic point of view, Gozo Island is considered an attractive geotourist destination due to its high environmental, cultural and geological heritage. In particular, the study area hosts Roman remains and two important natural protected areas included in the Natura 2000 network. Moreover, the presence of quarrying areas contributes to increase the economic value of the study area.&lt;/p&gt;&lt;p&gt;The evaluation of coastal vulnerability refers to the methodological approach proposed in the framework of the EU-funded RISC-KIT project, partially modified to adapt the method to the context of the study area and to the available information. Specifically, the method is based on the evaluation of the exposed elements in the investigated area by applying a set of indicators related to the local land use, anthropogenic and natural assets, and economic activities. Furthermore, a social vulnerability indicator is applied to evaluate the socio-economic characteristics of the population potentially exposed to coastal hazards. Available data is overlaid and reclassified by means of specific GIS tools in order to obtain the overall vulnerability level of the investigated area, represented on a coastal vulnerability map.&lt;/p&gt;&lt;p&gt;Results highlight that 18.3% of the study area is characterized by high to very high vulnerability: including Marsalforn Bay, which hosts an extensive urban centre, and the area nearby Dahlet Qorrot Bay, where a natural protected site is located. Ramla Bay, a very important tourist attraction hosting the largest sandy beach in Gozo, is characterized by very high vulnerability. Most of the investigated area (61.3%), is however characterized by a medium level of vulnerability, while areas characterized by low vulnerability (20.4%) mainly correspond to abandoned agricultural fields and bare rocks outcrops.&lt;/p&gt;&lt;p&gt;This research represents a first attempt at the assessment of coastal vulnerability in the Maltese archipelago, and shows that the method used can be easily applied to other Mediterranean coastal areas providing policy makers with comprehensive coastal vulnerability information. The latter is crucial to approaching sustainability, through integrated coastal management.&lt;/p&gt;
