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.

Between 2010 and 2015, nocardiosis outbreaks caused by Nocardia seriolae affected many permit farms throughout Vietnam, causing mass fish mortalities. To understand the biology, origin, and epidemiology of these outbreaks, 20 N. seriolae strains collected from farms in four provinces in the South-Central Coast of Vietnam, along with two Taiwanese strains, were analysed using genetics and genomics. Pulsed-field gel electrophoresis identified a single cluster amongst all Vietnamese strains that was distinct from the Taiwanese strains. Like the PFGE findings, phylogenomic and single-nucleotide polymorphism (SNP) genotyping analyses revealed that all Vietnamese N. seriolae strains belonged to a single, unique clade. Strains fell into two subclades that differed by 103 SNPs, with almost no diversity within clades (0-2 SNPs). There was no association between geographic origin and subclade placement, suggesting frequent N. seriolae transmission between Vietnamese mariculture facilities during the outbreaks. Vietnamese strains shared a common ancestor with strains from Japan and China, with the closest strain, UTF1 from Japan, differing by just 217 SNPs from the Vietnamese ancestral node. Draft Vietnamese genomes range from 7.55-7.96 Mbp in size, have an average G+C content of 68.2%, and encode 7,602-7,958 predicted genes. Several putative virulence factors were identified, including genes associated with host cell adhesion, invasion, intracellular survival, antibiotic and toxic compound resistance, and haemolysin biosynthesis. Our findings provide important new insights into N. seriolae epidemiology and pathogenicity and will aid future vaccine development and disease management strategies, with the ultimate goal of nocardiosis-free aquaculture.

<p>Located in the middle position of the country, all provinces/cities in the South Central Coast border the sea. With a total coastline length of 1,430 km, accounting for 43.8% of the whole country's coastline (3,260 km), the sea and island tourism in the South Central Coast is now considered a spearhead economic sector, which plays an important role in socio-economic development of this area. In this article, the authors have deeply analyzed the situation and the issues in developing the sea and island tourism in the South Central Coast region from 2010 up to now. Thence, findings lead to important practical suggestions to promote the sustainable development of the sea and island tourism in the South Central Coast in the coming time.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0616/a.php" alt="Hit counter" /></p>

Phu Quy island – Binh Thuan province, is 120 km southeast of Phan Thiet city, where the long – lasting destruction of waves, wind, and rain into oceanic volcanic materials formed four significant geomorphological heritages. These geomorphosites have scientific and additional values (cultural, aesthetic, and ecological values), of which mountain Cao Cat cinder cones deserves to be a South Central Coast geomorphosite; while mountain Cam volcano, Hang Cliff – Nho beach erosion coast and Tranh volcanic islet are proposed at a local level. The impressive cliffs exposed layers of coarse and steeply sloping sediments caused by blasting; erosion coastal terrain such as cliffs, rocky headlands, stacks, arch, islets, etc. all shapes and colors associated with landmarks such as Mong Tay tack, Gam inlet, Ban inlet, Xuong Ca headland, Phat inlet, Dried Squid pond, Den islet, Giua islet, Do islet... are outstanding scientific values. Furthermore, Sa Huynh cultural relics (2,500 – 3,000 years ago) discovered in mountain Cao Cat; Linh Son, and Linh Buu ancient pagodas; Phu Quy landscape viewpoints from mountain Cam Lighthouse or colorful coral reefs on Tranh islet... are additional values that increase the worth of Phu Quy island's geomorphosites. Interpreting the scientific and additional values of these geomorphosite with images, books, geometrically similar models, etc. would promote the geotourism – a niche of the sustainable tourism market that is developed along with Global Geoparks recognized by UNESCO.

A New Species

Orchidantha anthracina (Lowiaceae), discovered at the south central coast of Vietnam, is described and illustrated, bringing the total number of species in the family to 26, of which four occur in Vietnam. The notes on distribution, habitat and etymology are given and a preliminary conservation assessment is provided. The species is compared with O. vietnamica, with which it shares flowers of similar size and colours, but from which it is readily distinguished by a narrow and strongly reflexed dorsal sepal and spreading lateral sepals, not supporting the labellum. Notes with additional comparison to all species with a similar arrangement of lateral sepals are also provided.

In Vietnam, drought is one of the natural disasters caused by high temperatures and lack of precipitation, especially with El Nino and the global warming phenomenon. It affects directly environmental, economical, social issueproblems, and the lives of humans. Many methods have been used to assess drought, andin which remote sensing indices are considered the most commonly used tool today. They are used to analyze spatio-temporal distribution of drought conditions and identify drought severity. Especially with the launch of Google Earth Engine (GEE) - a cloud-based platform for geospatial analysis, it is easy to access high-performance computing resources for processing multi-temporal satellite data online. With the GEE platform, we focus on writing and running scripts with the indicators suitable for evaluating drought phenomenon, instead of calculating on software and downloading remote sensing imagery with large size. In this study, we collected 26 Landsat 8 images in the dry season in 2019 (from April to July) in Tay Hoa district, Phu Yen – a region in the South Central Coast of Vietnam where agricultural drought occurs frequently. wWe assessed the distribution of drought conditions in the dry season in 2019 in Tay Hoa district, Phu Yen – a region in the South Central Coast of Vietnam where agricultural drought occurs frequently by using a drought index (VHI index – Vegetation Health Index) produced from Landsat satellite data in the GEE platform. The study results indicated that the drought (from mild to severe) concentrated in the North of the region, corresponding to high surface temperature and NDVI low or NDVI moderate values. VHI maps were visually compared with the drought map of the South Central Coast and the Central Highlands. In general, the results also reflect the the method’s reliability and can be used to support the managers to plan policies, making long-term plans to cope with climate change in the future at Tay Hoa in particular and other regions in general.
