The first exotic specimen of Penaeus monodon (tiger shrimp) was recorded in the most important shrimp fishing ground of Veracruz, Mexico. In February 2014, one individual of 29 cm LT was collected at 90 m depth off South-central coast of Veracruz at 22 Km northwest of Coatzacoalcos port and 150 Km southeast from Alvarado. The tiger shrimp was introduced in Cuba in 1986 for cultivation. In 2013 the presence of nine individuals in the Campeche coast was reported. This recording evidence the movement of P. monodon into the Gulf of Mexico which is a concern because of their possible impact on local shrimp populations and their ecosystem.

The research focuses on using Sentinel-2 that can be integrated with the Digital Shoreline Analysis System (DSAS) as an effective tool for the determination of changes in the riverbanks and using linear regression to predict shoreline changes. The research applied the assessment of shoreline changes in the period of 2015- 2020 and forecast to 2025 in Laigiang river of the South Central Coast region of Vietnam. Based on the DSAS tool, parameters such as Shoreline Change Envelope (SCE), Net Shoreline Movement (NSM), End Point Rate (EPR) and Linear Regression Rate (LRR) were determined. The analysis results show that the accretion process in the Laigiang river in the period of 2015-2020 with the accretion area ranges from 81.47 ha. Meanwhile, the area of shoreline erosion only fluctuates around 54.42 ha. The rhythm of evolution is a determinant element for this transitional system.

Flood hazards affect the local economy and the livelihood of residents along the South-Central Coast of Vietnam. Understanding the factors influencing floods’ occurrence potentially contributes to establish mitigation responses to the hazards. This paper deals with an empirical study on applying a combination of the fuzzy analytic hierarchy process (AHP), the fuzzy technique for order of preference by similarity to ideal solution (TOPSIS), and a geographic information system (GIS) to assess flood hazards along the South-Central Coast of Vietnam. Data are collected from focus group discussions (FGDs) with five communal authorities; a questionnaire completed by eight hamlet heads in the Phuoc Thang commune (Binh Dinh province); and documents, reports, and thematic maps provided from official sources. A total of 12 maps of flood factors are prepared. The results show that terrain elevation, creek-bottom terrains, high tide-induced flooding area, and distance to water body are the main factors affecting flood hazards. The An Loi hamlet faces the highest risk for floods, followed by Lac Dien, Luong Binh, and Pho Dong. The map of flood hazards indicates the western part is assessed as low hazard, whereas the eastern part is a very high hazard area. The study findings show that the hybrid approach using GIS-based fuzzy AHP–TOPSIS allows connecting decision makers with the influencing factors of flooding. To mitigate floods, both the Vietnam national government and the Binh Dinh provincial government should integrate natural hazard mitigation into socio-economic development policies.

The Ca Ong (whale) belief is one of the folk beliefs in Vietnam. The Ca Ong belief followed by the inhabitants of the Ly Son island district not only reflects their spiritual needs, but also educates people in the value of gratefulness. Thus, at the temple, the practitioners of the Ca Ong belief often hang many horizontal lacquered boards (hoành phi) with parallel sentences in the main hall, with the purpose of explicating the aforementioned values. This belief also reflects the aspirations of the island inhabitants, who wish to have their lives blessed with happiness by the god. Particularly, this paper explores the divergence of the Ca Ong belief that can be found in this island. Namely, this belief is not only worshipped at the temple by the community, but also privately within the Dang family, where they worship Ca Ong as a god. This is something never happening in other regions such as the South Central coast or the South of Vietnam. Furthermore, this paper focuses on the change of the title system within this belief. Whereas titles were previously bestowed by the Nguyen dynasty, family titles in the Ly Son Island are bestowed by the Shaman.
