Wilayah pesisir sangat unik, dinamis, dan kompleks karena merupakan zona interaksi antara daratan, lautan, dan atmosfer. Hal ini menjadikan wilayah pesisir sebagai wilayah yang paling rentan di Bumi. Untuk mengetahui seberapa besar kerentanan di suatu wilayah pesisir, perlu dilakukan penelitian untuk mengetahui tingkat kerentanan wilayah pesisir dan faktor yang mempengaruhi. Penelitian mengenai tingkat kerentanan pesisir di lokasi ini pernah dilakukan pada tahun 2016 dan diperoleh simpulan bahwa tingkat kerentanan pesisir berada pada kategori sedang. Dengan semakin berkembangnya pemanfaatan potensi di daerah tersebut maka dirasa perlu dilakukan penelitian serupa dengan tahun 2016 untuk mengetahui apakah terdapat perubahan tingkat kerentanan antara tahun 2016 dengan tahun 2020. Data-data yang digunakan terdiri dari Data-data yang digunakan terdiri dari  geomorfologi pantai, pasang surut, citra satelit Landsat 7 ETM+ dan 8 OLI, kenaikan muka laut dan DEM. Analisis data menggunakan metode Coastal Vulnerability Index (CVI). Hasil penelitian menunjukkan tingkat kerentanan pesisir di lokasi penelitian berada pada kategori rendah-sedang, dengan kisaran skor CVI 9,93-25,86. Topografi, geomorfologi, intensitas perubahan garis pantai, dan kemiringan pantai merupakan faktor yang dapat menyebabkan tingkat kerentanan di lokasi penelitian menjadi sangat tinggi. Namun, keterhubungan antara parameter lain yang dapat menjadi faktor penghambat tingginya tingkat kerentanan, menyebabkan tingkat kerentanan pesisir di lokasi penelitian hanya berada dalam kategori rendah-sedang. Terdapat perubahan kondisi tingkat kerentanan antara tahun 2016 dengan tahun 2020 dimana pada tahun 2020 tingkat kerentanan di pantai timur mengalami penurunan menjadi kategori rendah.

Many coastal areas and infrastructure suffered from unprecedented hazards such as storms, flooding, and erosion. Thus, it is increasing the vulnerability of urban coastal areas aggravated with the absence of coastal green infrastructure. Given the state of coastal environments, there is a genuine need to appraise the vulnerability of coastal cities on the basis of the latest projected climate scenarios and existing condition. Hence, to asses, the vulnerability level of Mataram coastal, the Coastal Vulnerability Index (CVI) accompanied by pre-assessment of readiness to climate disruption. The CVI used to map coastal into five classes of using GIS. As a case study, this approach applied to Mataram City: one of the tourism destinations in Lombok. Two of sub-districts in Mataram City, Ampenan and Sekarbela, laying in the shorelines have undergone coastal flooding and erosion. One of them, Ampenan sub-district, experienced flooding due to river-discharge and became the most severe location during inundation. Results indicated that along ±9000 meters of Mataram coast possess vulnerability level in moderate to very high-risk level. The assessment also showed that sea-level rise is not the only critical issue but also geomorphology and shoreline changes, the existence of green infrastructure, also human activity parameters took important part to be assessed.

Climate change has brought about many threats to the ecosystem by inducing natural hazards, particularly sea level rise. Coastal areas then are subjected to many adverse effects of sea level rise, hence posing a risk to the safety of the coastal population, resources and assets. As part of the mitigation and adaptation measures against these effects, the Coastal Vulnerability Index (CVI) was implemented by many coastal regions. The CVI is an index-based tool to map the risks related to coastal changes. In Malaysia, the practice of CVI is still in its initial stages. Whereby, the Department of Irrigation and Drainage (DID) Malaysia had earlier carried out two pilot projects on CVI. The first is located at Tanjung Piai and the second at the west coast of Pulau Langkawi. This paper reviews the definition and concept of CVI. An alternative implementation approach of CVI in Malaysia is also discussed.

Mapping Vulnerability

Binh Thuan coastal zone, nearly 192,9 km shoreline, is well known for residential, recreational areas and minor industries. Shoreline is vulnerable to accelerated sea level rise (SLR) due to its low topography and its high ecological. The present study has been carried out with a view to assess the coastal vulnerability of SLR. Coastal vulnerability map has been built to the calculating results of the place vulnerability index (PVI). The PVI is derived by summing the CVI (coastal vulnerability index) and CSoVl (coastal social vulnerability index) scores. CVI is calculated from nine variables: Geology, geomorphology, coastal slope(%), shoreline change rate (m/yr), mean elevation (m), shoreline direction, mean tidal range (m), wave height (m) and SLR (mm/yr). We use two socioeconomic variables for CSoVI which are socioeconomic variable and relative distance to coast. Results of the vulnerable areas analysis indicate that 120,73 km2 is at very high vulnerable, 84,96 km2 high, 109,23 km2 moderate, 113,99 km2 low and 232,20 km2 very low. The method in this study which combine CVI, CSoVI and PVI together is new protocol of coastal vulnerability assessment for Vietnam coastal zone due to future SLR.

Coastal Damage

The coastal areas of both Jayapura Municipality and Regency which is directly opposite to the Pacific Ocean with the multifunctional use is a vulnerable area to disasters. The coastal vulnerability is determined by considering some influential factors, that is geomorphology and elevation to minimize the coastal damage impacts. The purpose of this study is to determine the coastal vulnerability index of Jayapura City and Regency focusing on the coastal geomorphology and elevation. The study area covers a coastal area of 241.86 km along the coastlines of Jayapura Municipality and Regency. The study method includes data collection on the coastal geomorphology and elevation characteristics. The value of coastal vulnerability index of each parameter is determined by dividing into five categories of coastal vulnerability. The result shows territorial division as follows: 145.88 km (61.18%) was not vulnerable, 33.14 km (13.90%) was less vulnerable, 29.03 km (12.17%) was a moderate vulnerability, 12.12 km (5.08%) was vulnerable, and the remaining 18.29 km (7.67%) was very vulnerable. The coastal vulnerability of Jayapura City coastal areas categorized into three classes, i.e. not vulnerable, moderate vulnerable and vulnerable, while the Jayapura Regency coastal areas felt into the following classes: not vulnerable and moderate vulnerable. The most vulnerable areas were of Abepura District, South Jayapura District and Muaratami District, all in the Jayapura Municipality administration. Those areas with high elevation level were not vulnerable at all.

Index Value

Some functions of mangrove areas in coastal ecosystems as a green belt, because mangrove serves as a protector of the beach from the sea waves, as a good habitat for coastal biota and for nutrition supply. Decreased condition or degradation of mangrove habitat caused by several oceanographic factors. Mangrove habitats have some specific characteristics such as salinity, tides, and muddy substrates. Considering the role of mangrove area is very important, it is necessary to study about the potential of mangrove habitat so that the habitat level of mangrove habitat in the east coast of Semarang city is known. The purpose of this research is to obtain an index and condition of habitat of mangrove habitat at location of research based on tidal, salinity, substrate type, coastline change. Observation by using purposive method and calculation of habitat index value of mangrove habitat using CVI (Coastal Vulnerability Index) method with scores divided into 3 groups namely low, medium and high. The results showed that there is a zone of research belonging to the medium vulnerability category with the most influential variables is because there is abrasion that sweeps the mangrove substrate. Trimulyo mangrove habitat has high vulnerable variable of tidal frequency, then based on value variable Salinity is categorized as low vulnerability, whereas for mangrove habitat vulnerability based on variable type of substrate belong to low and medium vulnerability category. The CVI values of mangrove habitats divided into zones 1; 2; and 3 were found to varying values of 1.54; 3.79; 1.09, it indicates that there is a zone with the vulnerability of mangrove habitat at the study site belonging to low and medium vulnerability category.
