“…The negative impacts of sea surface temperature, rainfall, typhoons, and wind speed on catch yields are also found in various literature in Vietnam [ 61 ] and other places [ 17 , 27 , 42 , 47 , 62 – 64 , 71 , 73 , 84 ]. For instance, Garza-Gil, Torralba-Cano [ 84 ] report a 10% rise in temperature leading to a 1.4% annual decrease in the European sardine fishery’s profit.…”

“…Precipitation affects species’ growth by changing the water environment, such as salinity and contamination [ 60 ]. Typhoons keep fishers away from production, damage vessels [ 61 ], and increase marine contamination [ 62 ]. Southern Oscillation, including El Niño and La Niña, may alter fish flows and affect total catches [ 63 , 64 ].…”

Welfare impact of climate change on capture fisheries in Vietnam

Fisheries are forecasted to shrink in the tropics due to climate change. In Vietnam, fisheries are a pro-poor economic sector and essential nutrition source; however, welfares of producers and consumers in the climate change context are not well understood. While most studies focus on the gains or losses of total products and revenues, this paper pays additional attention to the changes in surpluses of market players in the long run. A combination of the production function, demand and supply functions, and partial equilibrium analysis is employed to measure the production and welfare impacts based on time series data from 1976 to 2018 and a Vietnam household living standards survey in 2018. The results show that relative to the present, catch yield is likely to reduce 35%-45% by mid-century and 45%-80% by the end of the century. Consumers may lose their surplus of 7-9 billion USD (PPP, 2018) by 2035 and 10-18 billion USD by 2065 due to supply reduction, while producers may gain additional profit of 3.5-4.5 billion USD by 2035 and 5-9 billion USD by 2065 owing to a price increase. The research findings suggest that Vietnam could impose measures to limit capture effort, as set out in the Law of Fisheries 2017, without harming fisher welfare. The expansion of aquaculture could reduce the gap between supply and demand of wild fish to mitigate consumer welfare loss; however, this impact is still ambiguous.

“…Given that the majority of Ha Long cultural inhabitants were descendants of indigenous hunter-gatherers and exhibited distinct cultural contexts with other farming groups in northern Vietnam, the foxtail millets discovered in Bai Ben and Bai Cat Don were perhaps acquired through exchanges or trades. As mentioned, from an archaeological perspective, the Ha Long group appears to have sustained contacts and exchanges with other groups, such as Phung Nguyen, Ha Giang, Mai Pha (Lang Son), Hoa Loc, and offshore islands along the South China Sea coast ( Ha, 2005 ; Nguyen, 2005b ; Nguyen, 2019 ). However, another possibility is that the people of Bai Ben and Bai Cat Don practiced a specific scale of millet farming on their own, as a stone knife-like fragment, typically used for crop harvesting, has been found at Ba Vung ( Chen, 2007 ), one of the Ha Long cultural sites.…”

Research has generally outlined that the Neolithic East Asian farmers expanded into Southeast Asia, leading to substantial social and cultural transformations. However, the associated archaeobotanical evidence until now has been insufficient to clarify the exact timing, dispersal route, and farming package of the emergence of agriculture in Mainland Southeast Asia. To clarify these issues, the micro-plant remains of phytolith and starch from three Neolithic sites in Ha Long Bay were extracted and analyzed. This study validates the earliest evidence of co-cropping in northern Vietnam, involving the cultivation of rice together with foxtail millet at 4000 years BP or slightly earlier. Moreover, the results indicate that at least two patterns of subsistence strategy were practiced simultaneously during the initial farming phase in the region. The Trang Kenh people, a regional variant of the Phung Nguyen cultural group often have been seen as the first farmers in northern Vietnam, and they mainly practiced a cereal-based subsistence strategy with more vital cultural characteristics of southern China origin. Meanwhile, the Ha Long people, mainly composed of indigenous hunter-gatherer descendants, continued to utilize a wide range of their preferred plant resources such as taros, yams, and acorns, while they absorbed and incorporated new elements such as millet and rice into their food system. This study provides solid information to understand the diverse economic systems among different cultural groups in Vietnam.

“…It is adjacent with the natural geography of southern China, where the diversity of extant vascular plants is extraordinary [ 1 ]. The flora of Vietnam is also rich in species composition, with more than 20,000 plant species recorded [ 2 ], containing many endemic taxa and key and primitive taxa of angiosperm phylogeny, possibly the origin of East Asian flora, and even angiosperms [ 3 ]. Therefore, Vietnam is a significant bioregional area in terms of physical geography and biogeography, necessitating biodiversity conservation.…”

Vietnam is extremely rich in biodiversity, with a remarkable range of habitats and more than 13,500 species of vascular plants recorded for the flora of Vietnam. This number represents about 3 to 5% of the world’s diversity of vascular plants. Over the past 30 years, there were two important documents on the vascular plants of Vietnam published, An Illustrated Flora of Vietnam (IFV) and Checklist of Plant Species of Vietnam (CPSV). During the past half century, the advent of molecular phylogenetics has witnessed dramatic changes in the classifications of vascular plants, and some modern classification systems of vascular plants have been established, e.g., PPG I, GPG, and APG. However, the vascular plants of Vietnam have not yet been classified according to these modern classification systems. In this paper, we present the history of the classification of vascular plants in Vietnam, compare the circumscription of all families of vascular plants occurring within Vietnam in IFV, CPSV, and the modern classification systems when applicable, and summarize familial assignments of all controversial genera in the different classifications. Furthermore, we also arrange the 37 families of lycophytes and ferns occurring within Vietnam according to the latest classification system (PPG I) and the 8 families of gymnosperms according to the latest Christenhusz’s system (GPG). The 246 families of angiosperms are arranged according to the fourth edition of the latest Angiosperm Phylogeny Group (APG IV). These results are the foundation stones and would be helpful for future research on the flora of Vietnam and the arrangement of plant collections in Vietnamese herbaria based on the updated classifications.
