Abstract:
A study on gender roles in mangroves management was conducted in Trieu Phuoc and Trieu Do communes of Trieu Phong district, Quang Tri province to gain a better understanding of gender roles in mangrove management. Research showed that local people are mainly dependent on fishing and aquaculture around the mangroves. Women have a good understanding about the role of mangroves and they are associated with mangroves not less than men, but so far their role has been overlooked. Mangrove management process seems to exclude women. This reduces the common management capacity of community. In addition, communities do not have a common regulation on the management and protection of mangrove forest resources and environment. A number of solutions are recommended such as strengthening the participation of civil society and women in mangrove forest management, developing a mangrove protection strategy and community-based regulations including gender. Nghiên cứu về vai trò giới trong quản lý rừng ngập mặn (RNM) được thực hiện trên địa bàn 2 xã Triệu Phước và Triệu Độ của huyện Triệu Phong, tỉnh Quảng Trị nhằm có được sự hiểu biết hơn về vai trò giới trong quản lý RNM. Nghiên cứu đã chỉ ra rằng người dân ở đây chủ yếu sống dựa vào việc đánh bắt và nuôi trồng thủy sản tại khu vực RNM. Phụ nữ có hiểu biết khá tốt về vai trò crò RNM và họ gắn liền với RNM không kém nam giới, nhưng cho đến nay vai trò của họ gần như không được nhìn nhận. Công tác quản lý RNM còn hạn chế nữ giới tham gia. Điều này làm giảm năng lực quản lý chung của cộng đồng. Ngoài ra các cộng đồng vẫn chưa có quy ước chung về quản lý, bảo vệ tài nguyên và môi trường RNM. Từ đó nghiên cứu đề xuất một số giải pháp như tăng cường sự tham gia của các tổ chức dân sự và phụ nữ trong quản lý RNM, xây dựng chiến lược bảo tổn RNM và các quy ước quản lý RNM dựa vào cộng đồng bao gồm giới.

Abstract:
This study aims to create a flood extent map with Sentinel imagery and to evaluate impacts on agricultural land in the lagoon region of central Vietnam. In this study, remote sensing images, obtained from 2017 to 2019, were used to simultaneously map the land cover status of a flood in the Quang Dien district. This study highlights flooded areas from Sentinel-2 images by calculating some indicators such as the Land Surface Water Index (LSWI) and the Enhanced Vegetation Index (EVI). Comparisons between the floodplain samples (GPS point-based) and flood mapping results, with the ground-truth data, indicate that the overall accuracy and Kappa coefficients were 97.9% and 0.62 respectively for 2017; the values for 2019 were 95.7% and 0.77 for the same coefficients. Land use maps overlying the flood-affected maps show that approximately 11% of the agriculture land area was affected by floods in 2019 comparison to a 10% in 2017. Wet rice was the most affected crop with the flooded area accounting for more than 70% of the district under each flood event. The most affected communes are: Quang An, Quang Phuoc and Quang Thanh. This study provides valuable information for flood disaster planning, mitigation and recovery activities in Vietnam. Mục tiêu của nghiên cứu là lập bản đồ phân bố ngập lụt với hình ảnh vệ tinh Sentinel và đánh giá ảnh hưởng ngập lụt đến sử dụng đất nông nghiệp ở vùng đầm phá miền Trung, Việt Nam. Trong nghiên cứu này, ảnh viễn thám thu nhận giai đoạn 2017- 2019 được sử dụng để xây dựng bản đồ hiện trạng sử dụng đất tại thời điểm bị ngập nước trên địa bàn huyện Quảng Điền. Nghiên cứu đã xác định được vùng ngập lụt ở huyện Quảng Điền bằng phương pháp phân loại chỉ số mặt nước (Land Surface Water Index – LSWI) và chỉ số khác biệt thực vật (Enhanced Vegetation Index-EVI) từ ảnh Sentinel-2. Xác định vùng nước lũ bị che khuất bởi mây bằng mô hình số hóa độ cao (DEM). Kết quả phân loại vùng ngập lụt được so sánh với giá trị tham chiếu mặt đất cho thấy độ chính xác tổng thể và hệ số Kappa đạt được trong năm 2017 là 97,9% và 0,62; trong khi năm 2019 đạt 95,7% và 0.77. Bản đồ sử dụng đất chồng lên bản đồ lũ lụt cho thấy khoảng 11% diện tích đất nông nghiệp bị ảnh hưởng bởi lũ lụt năm 2019 so với 10% năm 2017. Cây lúa nước là cây trồng bị ảnh hưởng nặng nề nhất, với diện tích bị ngập lụt chiếm hơn 70% diện tích lúa của huyện. Các xã bị ngập lớn là xã Quảng An, Quảng Phước và Quảng Thành. Nghiên cứu này cung cấp thông tin có giá trị cho các hoạt động lập kế hoạch, giảm nhẹ và phục hồi thiên tai lũ lụt ở Việt Nam.

Abstract:
The research aims to assess the current groundwater resources management in Bac Lieu province. The combination of descriptive statistic and interview approach (including individual interview and key informant panel) were applied based on the principles of water governance framework developed by the Organization of Economic Co-operation and Development (OECD) to assess the policy coherence and the transparency and stakeholder engagement of the groundwater management. The study showed that the current groundwater resources management improved overtime; however, the policies were not completely sufficient and the responsibility of the units related to the groundwater resources management was not indicated clearly yet. Thus, overlaps in function of different management units are found and the access of the local people to the groundwater management was limited. In addition, the stakeholder involvement in managing the groundwater resources was in short of both amount and qualification. The separation of powers seems to be higher and higher, the local government has the main responsibility to manage the groundwater and the communities, especially the local people still have low rate of participation in the groundwater resources management process. Nghiên cứu được thực hiện nhằm đánh giá hiện trạng quản lý nguồn tài nguyên nước dưới đất (NDĐ) tại tỉnh Bạc Liêu. Sự kết hợp giữa phương pháp thống kê mo tả va phương pháp phỏng vấn (bao gồm phỏng vấn cá nhân và phỏng vấn chuyên gia)dựa trên những quy định về quản trị tài nguyên nước của Tổ chức Hợp tác và Phát triển Kinh tế (OECD – Organization for Economic Co-operation and Development) được áp dụng để đánh sự chặt chẽ của các chính sách quản lý, sự minh bạch của công tác quản lý và sự tham gia của các bên có liên quan. Kết quả cho thấy, cơ chế quản lý nguồn tài nguyên NDĐ đã và đang dần hoàn thiện, song các chính sách quản lý vẫn còn chưa đầy đủ và trách nhiệm của các đơn vị quản lý vẫn chưa được quy định rõ ràng. Vì vậy, đến nay công tác quản lý còn phát sinh sự chồng chéo và thiếu sự phối hợp giữa các cơ quan chức năng có liên quan cũng như sự liên kết giữa cơ quan quản lý địa phương và người sử dụng tài nguyên NDĐ. Thêm vào đó, các bên có liên quan tham gia vào quản lý nguồn tài nguyên NDĐ còn hạn chế về cả số lượng và năng lực, trong đó chính quyền địa phương là đơn vị quản lý chính; do vậy, sự tập trung quyền hạn vào một chủ thể (chính quyền địa phương) là rất cao và sự tham gia của cộng đồng, đặc biệt là người sử dụng NDĐ, còn hạn chế.

Abstract:
Globally, planted forests are increasing, providing increased resources to forest industries and ecosystem services (ES) to local and wider communities. However, assessment of the impacts of plantations on ES has been limited. Planted forests have expanded rapidly in Vietnam over the last 20 years, with much of the planting undertaken by smallholder growers using exotic Acacia and Eucalyptus species. This study aimed to test a framework to assess changes in four ES due to an increase in Acacia plantations from 2005–2015 in central Vietnam: carbon sequestration, sediment retention, water yield and habitat. Quantitative and qualitative indicators for each service were derived from the literature. Results showed that the area of planted forests in Quảng Trị and Thừa Thiên-Huế Provinces increased from 130,930 hectares (ha) to 182,508 ha, mostly replacing non-forest areas (degraded lands, grasslands and agricultural lands) and poor forests. The framework demonstrated capacity to assess the effect of planted forests on wood flow, carbon stocks, sediment retention, streamflow and the extent of wildlife habitat. Apart from the wood supply and carbon sequestration, more research is required to translate biophysical indicators to benefit relevant indicators related to human welfare. The study also revealed that the area of rich forests decreased by 20% over the ten years, mostly through degradation to poorer quality natural forests. Therefore, at the landscape scale, improvement in ES due to conversion of non-forests to planted forests was offset by a reduction in some services as a result of degradation of native forest from rich to poorer condition. Assessment of changes in ES due to planted forests also needs to consider other landscape changes. These analyses can inform policymakers, forest owners and managers, environmental organizations and local communities of the benefits and impacts of planted forests and provide an improved basis for payments for ES and potential additional income for smallholder tree growers.

Abstract:
Climate change has been affecting to livelihoods of communities in the coastal plain of the Vietnamese Mekong Delta (VMD). Surface water management in the coastal plain was considered to be limited, especially in enforcement. Therefore, the research aimed to assess the stakeholder involvement, identify the conflict in using the surface water and mechanism to solve and avoid the conflict. The directive interview farmers and governmental staffs was implemented to collect the necessary data. The descriptive statistic was applied in order to analyze the collecting data through farmer survey. The questionnaire was built based on the governance assessment framework “Ten-building Block”. The results showed that the governmental group (including the people committee and the Provincial department) was the highest participatory in the management process both in decision-making level and interested level. The surface water users, especially the farmers participated with the average rate because of their low capacity in making the decision for a new policy or a new agricultural model. Besides, different groups of stakeholders as the non-governmental organization and governmental organization (the local Youth Union, Famer’s and Women’s Association) played an important role in raising the water user’s awareness. The remaining group, including non-agricultural company or traders, nearly were not concerned about the surface water changes. In addition, there were two main types of conflicts identified: between the farmers in the same kind (1) and different kind (2) of cultivation. As the consequence of the natural salinity and the impacts of output water from shrimp pond to the rice cultivation zone, the conflict was about the inefficient water regulation and distribution for each water user. These conflicts were mostly solved through self-negotiating and self-engaging between the farmers. In fact, there was no rule or principle to solve and prevent the potential water use conflict. Thus, this could be a great challenge for the surface water management in the agricultural zone as Soc Trang in the context of increasing the extreme climatic phenomenon. Biến đổi khí hậu đã và đang tác động lớn đến sinh kế của các cộng đồng ven biển đồng bằng sông Cứu Long (ĐBSCL). Công tác quản lý tổng hợp tài nguyên nước mặt tại vùng ven biển được cho rằng còn tồn tại nhiều hạn chế, nhất là trong triển khai và thực thi. Vì vậy, nghiên cứu được thực hiện tại Sóc Trăng (một tỉnh ven biển ĐBSCL) nhằm đánh giá sự tham gia của các thành phần có liên quan, xác định các mâu thuẫn trong sử dụng nguồn nước mặt cũng như các giải pháp giải quyết và phòng tránh mâu thuẫn. Phương pháp phỏng vấn trực tiếp nông hộ, tham vấn chuyên gia quản lý và thống kê mô tả được áp dụng để đánh giá các mục tiêu đặt ra của đề tài. Các thông tin khảo sát được xây dựng dựa trên bộ mười tiêu chí đánh giá quản trị tài nguyên nước (van Rijswick et al., 2014). Kết quả cho thấy nhóm chính quyền địa phương (bao gồm UBND và các Sở/Ngành) có vai trò và mức độ tham gia cao nhất trong chu trình quản lý. Người sử dụng nước mặt, nhất là nông dân đóng góp sự tham gia tương đối do mức đô ra quyết định về thiết lập chính sách và lựa chọn mô hình canh tác thấp. Mặt khác, các nhóm đối tượng khác như các tổ chức phi chính phủ, Đoàn thể, Hội nông dân và Hội phụ nữ đóng góp vai trò quan trọng trong nâng cao nhận thức và kêu gọi cộng đồng sử dụng hiệu quả nguồn nước mặt. Các nhóm tổ chức kinh tế như doanh nghiệp, tiểu thương gần như không quan tâm đến nguồn nước mặt. Bên cạnh đó, các mâu thuấn về sử dụng nước mặt cũng được xác định. Các mâu thuẫn được phân chia thành 2 nhóm: cùng loại hình canh tác và giữa các loại hình canh tác khác nhau. Các mâu thuẫn chủ yếu về vấn đề điều tiết nguồn nước không hợp lý và thiếu cân bằng trong phân phối nước ngọt cho các đơn vị canh tác do xâm nhập mặn tự nhiên, xả thải nước mặn vào vùng ngọt và khai thác không đồng đều. Các mâu thuẫn này chủ yếu được giải quyết thông qua thương lượng và thỏa thuân giữa các đối tượng có liên quan chứ chưa có bất kỳ một cơ chế hay quy định nào nhằm giải quyết cũng như phòng tránh các mâu thuẫn tiềm tàng. Vì vậy, đây sẽ là một thách thức lớn cho công tác quản lý nguồn nước mặt tại vùng sản xuất nông nghiệp thâm canh như Sóc Trăng trong bối cảnh gia tăng cực đoan khí hậu.

Abstract:
During the US – Vietnam War (1961 – 1972), Vietnam was subjected to widespread spraying of the chemical herbicide that is also called Agent Orange containing the most toxic dioxin congener, of 2,3,7,8-Tetrachlorodibenzo(p)dioxin (2,3,7,8-TCDD). A Luoi district belongs to Thua Thien-Hue province, located in the western part of the North Central coast region of Vietnam. During the Ranch Hand campaign (1965 -1970), A Luoi was heavily sprayed with this herbicide. In order to assess potential human health risks for people due to 2,3,7,8-TCDD exposure from contaminated soil, more than 50 soil samples were collected in A Luoi district area in 2013 and 2014 to determine dioxin concentrations by HRGC/HRMS. Human health risk assessment was applied using internationally recognized approaches. Hazard Quotient (HQ) values, assuming 2,3,7,8-TCDD to be a threshold contaminant, were calculated to be 13.2 and 6.1; and Incremental Lifetime Cancer Risk (ILCTR) values, assuming 2,3,7,8-TCDD to be carcinogenic non threshold, were 0.00314 and 0.00627 for adults and children, respectively. These results from exposures in A Luoi show risk values, which are several hundred times higher than acceptable TRVs. The results of this study indicate that, although the war ended nearly 50 years ago, communities living in A Luoi are still at risk of residual dioxin exposure from soils contaminated. Therefore, risk management and mitigation measures are needed, including targeted soil remediation and provision of improved medical and health systems. To our knowledge, this is the first human health risk assessment (HRRA) study in areas sprayed by herbicides during the war in Vietnam. Trong thời kỳ chiến tranh giữa Mỹ và Việt Nam (1961 - 1972), Việt Nam phải hứng chịu một lượng lớn chất diệt cỏ còn gọi là chất Da cam, trong đó chứa chất hóa học siêu độc 2,3,7,8-Tetrachlorodibenzo (p) dioxin (2,3,7,8-TCDD). Huyện A Lưới thuộc tỉnh Thừa Thiên-Huế, nằm ở phía tây của vùng duyên hải Bắc Trung Bộ Việt Nam. Trong chiến dịch Ranch Hand (1965-1970), huyện A Lưới đã nhiều lần bị phun rải chất diệt cỏ này. Trong 2 năm 2013 và 2014, hơn 50 mẫu đất và thực phẩm đã được thu thập ở khu vực huyện A Lưới và phân tích xác định nồng độ dioxin nhằm đánh giá rủi ro về sức khỏe đối với người dân sống trong vùng bị phun rải chất diệt cỏ trong chiến tranh. Nếu giả định chất 2,3,7,8-TCDD là chất độc có ngưỡng, giá trị HQ (hệ số rủi ro) tính được là 13,2 và 6,1; và nếu giả định 2,3,7,8-TCDD là chất độc gây ung thư không ngưỡng, các giá trị ILCR (nguy cơ ung thư tăng dần suốt đời) tìm được là 0,00314 và 0,00627, tương ứng đối với người lớn và trẻ em sống ở A Lưới. Khi so sánh với các giá trị TRVs (rủi ro chấp nhận được) cho thấy các giá trị rủi ro ở A Lưới cao hơn vài trăm lần. Từ kết quả này chỉ ra mặc dù chiến tranh đã kết thúc gần 50 năm trước, cộng đồng ở A Lưới vẫn có nguy cơ phơi nhiễm dioxin. Cần thiết phải sớm có các biện pháp quản lý rủi ro và giảm thiểu phơi nhiễm dioxin cho người dân, bao gồm việc xử lý đất và cung cấp các hệ thống bảo vệ môi trường, y tế và cải thiện sức khỏe. Đây là bài báo đầu tiên về đánh giá rủi ro sức khỏe cộng đồng dân cư do phơi nhiễm dioxin ở những vùng bị phun rải chất diệt cỏ trong chiến tranh.

<p><strong>Abstract: </strong>This study undertakes an economic analysis of selected sustainable land management (SLM) models in three selected provinces: Hoa Binh province in the Northwestern Mountainous region, Quang Tri province in the North Central Coast and Can Tho province in the Mekong Delta. The SLM models in Hoa Binh province are agroforestry models and those in the provinces of Quang Tri and Can Tho are annual crop rotations and intercropping with improved cultivation methods. The present study uses primary data from a multipurpose survey of 826 farm households. The results show that the agroforestry systems in Hoa Binh province are not financially attractive to farmers as their net returns are low, but their off-site benefit of soil erosion reduction in terms of safe removal and dumping cost of sediment is remarkable, about VND 300,000–320,000 per hectare per year. The SLM models in Hai Lang district (Quang Tri) are profitable with a much higher net return than that of prevailing non-SLM model with cassava mono-cropping. For Can Tho province, the SLM models with rice and upland crop rotations have significantly higher net returns than those of the triple-rice rotation model. However, the profitability of the studied SLM models is significantly affected by the risks associated with poor development or lack of outlet markets. Enhancing farmers’ agribusiness knowledge making them be able to deal with risks in the adoption of SLM models is of vital importance.</p><p>Keywords: sustainable land management economic analysis, Hoa Binh, Quang Tri, Can Tho</p><p> </p>

Abstract:
Three surveys were carried out in May, August and December 2014 at 7 sampling location to determine species composition of fish fauna in the coastal waters of Quang Ngai province (the Central Vietnam). A total number of 178 species of fishes were identified belonging to 125 genera, 68 families and 13 orders. Analysis of community structure of fish fauna showed that Perciformes order was the most popular, making up 71.9%; Tetraodontiformes (8.4%); Pleuronectiformes (5.6%). Serranidae family was the most abundant with 14 species, making up 7.9% of the total number of species; Carangidae: 12 species (6.7%); Lutjanidae, Gobiidae had the same number of species with 9 species (5.1%); Scombridae: 7 species (3.9%); Soleidae: 6 species (3.4%); Haemulidae, Mullidae, Tetraodontidae: 5 species (2.8%);... Cluster analysing based on the Bray-Curtis similarity index of nine fish faunas (Thai Binh, Son Tra, Thu Bon, Quang Nam, Nha Phu-Binh Cang, Ben Tre and Tra Vinh) showed that fish composition of the coastal estuaries of Tra Vinh and Ben Tre had the highest similarity (80%), subsequently fish fauna of Quang Ngai had similarity with that of Nha Phu-Binh Cang (39%), Quang Ngai and Quang Nam (42%), Quang Nam and Nha Phu-Binh Cang (41%), Quang Nam and Son Tra (38%), Thai Binh and Ben Tre (37%), Quang Ngai and Son Tra (36%). The result was also classified into two distinct groups of 7 fish faunas: Group 1-Tra Vinh, Ben Tre and Thai Binh; group 2-Quang Ngai, Quang Nam, Nha Phu-Binh Cang and Son Tra. The species richness (Margalef’s index) of Quang Ngai (34.2) was less abundant than other areas, the highest species richness belonged to Tra Vinh (38.2), Thai Binh (38.0), Quang Nam (37.8), Nha Phu-Binh Cang (35.1), Son Tra (30.9), Ben Tre (29.4). The diversity of species composition according to the level taxa in each region showed the characteristic of each fish fauna.

Abstract:
SUMMARYParagonimus westermani is one of the most medically important lung flukes and is widely distributed in Asia. It exhibits considerable variation in morphological, genetic and biological features. In central provinces of Vietnam, a high prevalence of metacercariae of this species has been reported from the crab intermediate host, Vietopotamon aluoiense. In this study, we detected P. westermani metacercariae in two additional crab hosts, Donopotamon haii in Quang Tri Province, central Vietnam and Indochinamon tannanti in Yen Bai Province in the north. The latter is a new locality for P. westermani in a northern region of Vietnam where P. heterotremus is the only species currently known to cause human paragonimiasis. Paragonimus westermani metacercariae found in Vietnam showed considerable morphological variation but slight genetic variation based on DNA sequences from the nuclear ribosomal ITS2 region and the mitochondrial 16S gene. Co-infection of the same individual crabs with P. westermani and P. heterotremus and/or some other Paragonimus species was found frequently, suggesting potential for co-infection in humans. The findings of the present study emphasize the need for highly specific molecular and immunodiagnostic methods to differentially diagnose between P. westermani and P. heterotremus infections.

Abstract:
The history (1951–2016) and the risk of typhoon and storm surge in coastal areas of Vietnam are analyzed and evaluated based on the observation data, results of statistical and numerical models. The Monte Carlo method was used to construct a bogus typhoon. A coupled numerical model of Surge, Wave and Tide (called SuWAT) was used for simulation of storm surge. The results show that in the period of 1951–2016 there were many typhoons which landed and induced high storm surge on the coast of the North and the North of Center of Vietnam. During one thousand years, there have been 4,678 typhoons entering the coastal zone from Quang Ninh to Ca Mau. In particular, the most severe typhoon in coastal area from Quang Ninh to Thanh Hoa is at level 16 (Beaufort scale), Nghe An - Quang Tri at level 16, Quang Binh - Phu Yen at level 17, Binh Dinh - Ninh Thuan at level 15 and Binh Thuan - Ca Mau at level 13. The coastal areas with highly vulnerable storm surge are provinces from Quang Ninh to Hai Phong (4.5 m), Thanh Hoa to Nghe An (4.0 m), Quang Tri (5.0 m). The results of this study are the basis for the preparation to cope with strong/super typhoon in the coast of Vietnam.

Abstract:
This paper is aimed at analysing the impacts of financial preparation and disaster experience on households’ disaster risk perception, including perceptions of likelihood and severity in Quang Binh Province of Vietnam, one of the areas strongly affected by natural disasters and climate change. With the data from direct surveying 308 households in Quang Binh province, the research methodology includes Cronbach’s Alpha, EFA and OLS regression models. The key findings are: First, disaster experience has positive impact on natural disaster risk perception. Second, financial preparation has negative impact on natural disaster risk perception. Third, the risk of natural disasters in Quang Binh Province are increasing and unpredictable due to rapid economic growth and urbanization. This fact requires the Government, provincial commitees, and stakeholders to go beyond traditional coping methods, implement more customized policies and specific actions to try to reduce the risks of natural disasters. Keywords: disaster risk, disaster risk perception, financial preparation, disaster experience.

Abstract:
Segmenting H’rê music regions in the mountains of Quảng Ngãi is very difficult. In reality, the differences in music practices between the H’rê people and the H’rê regional dialects are unclear, as well as the problem of cross-cultural relationships in music taking place with neighboring ethnic groups. However, some scholarly approaches (Tô Ngọc Thanh, 1995; Lê Huy and Minh Hiến, 1994) still boldly segment the H’rê music with the desire to provide some scientific information about a cultural phenomenon of the H’rê people in a specific location. The article divides H’rê music practices in Quảng Ngãi into two relatively different regions: the center region and the suburban region. In particular, the center region includes the districts of Sơn Hà, Ba Tơ and Minh Long; The suburban region includes places that preserve, promote, reconcile music practices that are at risk of disappearance. In addition, the article also highlights the different elements of H’rê music practices in different regions of Quảng Ngãi province.

Abstract:
Vuong Huu Quang 王有光, with courtesy name Dung Hoi用晦 and poetic name Te Trai 濟齋, was a high-ranked mandarin of the Nguyen Dynasty. He was born in Tan Duc Village, Tan Long District, Phien An Town, Gia Dinh Province, Southern Vietnam, into a family of the Ming-Dynasty immigrants who originated from CangZhou County, Fujian Province. Vuong Huu Quang held many important positions in the imperial court across various localities and traveled to China for diplomatic mission twice in the fifth year of Thieu Tri Emperor (1845) and from the seventh year of Thieu Tri (1847) to the first year of Tu Duc Emperor (1848). His name, however, is unfamiliar to Vietnamese modern readers due to his limited written legacy, most of which was lost in history. Researchers have known of only two steles poems he left in China, one engraved on a stele in Wuxi and the other in the Yue Fei Temple. Upon reading the old collection Viet Nam Han van Yen hanh van hien tap thanh 越南漢文燕行文獻集成, I discovered that Vuong Huu Quang and his co-worker Pham Chi Huong enjoyed writing and responding in poetic form during their diplomatic trips to China. This article introduces several more poems of Vuong Huu Quang to expand our understanding of another Southern Vietnamese poet who have been mostly covered by time, and provides a brief analysis on the poetic style that Vuong Huu Quang and Pham Chi Huong applied in portraying historical figures.

Abstract:
Vietnam’s forestry policies have expanded the area of planted forests in order to meet the supply of raw materials for the timber processing industry. However, the diversity and volume of demand in the industry have also increased, and a shortage of raw materials can be assumed. For clarifying the correspondence of stakeholders, we explore changes in the resource supply behavior of forestry companies and procurement strategies of companies that manufacture lumber for glued laminated timber, medium density fiberboard (MDF) and wood pellets. Next, we discuss issues and future developments surrounding the supply and demand for timber from planted forests. According to a survey of Quang Tri Province, both industrial and on-farm tree planting play an important role in Vietnam’s wood industry. The origin of the supply has been categorized according to its purpose (products). On the other hand, with the declining supply of imported timber and natural forest timber, inquiries from sawmills and glued laminated timber factories for timber from planted forests have increased, and wood pellet manufacturers are facing competition for raw material procurement with MDF manufacturers, and the supply of timber from planted forests is becoming scarce. The key to the solution lies in improving the low productivity of current on-farm tree planting. To this end, forming farmer groups upon the acquisition of forest certification will help achieve economies of scale and bargaining power.

Abstract:
Huong, Thach Han and Kien Giang rivers are the important surface water sources in Thua ThienHue, Quang Tri and Quang Binh provinces, respectively (in Central Vietnam). The river water samples were taken monthly (from June 2001 to May 2002 for Kien Giang river and from January to December of 2004 for Thach Han and Huong rivers) at selected sites. The temperature, pH, conductivity (EC), salinity, turbidity (TUR), DO, COD, BOD5, nitrate, ammonia, phosphate, total solids (TS), hardness, total dissolved iron, total coliform (TC), fecal coliform (FC) and sodium adsorption ratio (SAR) of water samples were analyzed. Water quality index developed by Bhargava (Bhargava-WQI) was modified and applied to assess water quality of the above mentioned rivers. Based on Bhargava-WQI, the classification and zoning of the rivers for beneficial uses were carried out. The results obtained show that the water quality index can be used as an efficient tool for the water quality management and water pollution control of the rivers.

Abstract:
In the paper, the author reviews the most recent important archaeological discoveries with Dong Son bronze drums (Heger I) found from Highlands (Kontum, Gia Lai, DakLak, Lam Dong provinces), Southern Part of Central Vietnam (Quang Nam, Quang Ngai, Binh Dinh, Phu Yen, Khanh Hoa provinces) and Southern Vietnam (Binh Dương, Binh Phuoc, Ba Ria-Vung Tau, Ben Tre, Kien Giang provinces). The author points out “key sites” in the South Vietnam – the typical sites and artifacts most lively showing “the convergance of Indigenous - Exogenous culture” in ancient villages, workshops for metallurgy, cemeteries, treasures, etc., which are related to the Dong Son and other inhabitants of the protohistorical epoch in Vietnam and Southeast Asia and beyond. There are Cemeteries or Tresors which contained Bronze Dong Son drums (Heger I type), bronze halberds (Ko), Western Han mirrors, Indian Nephrite or Glass and Golden Ornaments – artifacts not only representing the multi-linear relationship of the owners of Southern Vietnam with other Asian centres, but also were considered to be the symbol of power, authority, potential of military and polical function, social ranks and they reflected the unpeaceful situation of the contemporary society. The author emphasizes the very appearance of these Dongson drums as shown with 2 subtypes of Bronze Drum Collections: Original Dong Son (Heger I) Bronze Drum Collection and Imitative Bronze Drum Collection which was created according to "Dongsonian Style" thousands of years ago. The author emphasizes the very early appearance of the “exogenous” elements of culture-technique-art-religion in Southern Vietnam, which were adapted or completely modified to match the knowledge and psychology, aesthetic needs, and “Indigenous” beliefs – especially clear in traditional funeral concept thousands of years ago, as shown with distinction in “chiefdom cemetery”. Finallly, the author generalized data related to Bronze metallurgy at the Southern Vietnam area and came to some following remarks: 1/ Nam Bo - Vietnam was the early centre of Bronze Metallurgy at the Mainland Asia in the Proto-history, with the technology of casting in sandstone moulds. 2/ This Bronze casting industry together with its copper and alloy materials probably came from “Native land of Dong Son culture” – the “Bronze Triangle” or “Bronze Quadrilateral”: Dong Son – Yunnan – Guangxi – Guangdong – Khorat. Through various ways: directly via the East Sea to the South of Vietnam or indirectly through roads – via Sa Huynh cultural area and Tay Nguyen (Highlands) along the Mekong River to the South of Vietnam in the end. 3/ However, the southern metallurgy had their “own features” that were considered “non-Dong Son” by the author. The big and sophisticated bronze products such as Dong Son drums (Heger I type) or Chinese halberd (Ko or halberd), Art figurines such as statues of a pangolin (Manis javanica) or Amulets, statues depicting a dog chasing another animal, etc. only appeared in the Early Iron Age. Apart from some exotic intact goods such as Dong Son drums from Son Tinh, Daglao, Ben Tre, Bu Dang etc. and Western Han mirrors from Binh Yen, Go Dua, Phu Chanh, Kem Nac, most of the bronze products in the Early Iron Age in the South of Vietnam were cast on site, with their own characteristics that were “non-Dong Son” and “non-Chinese”. 4/ According to the author, the large bronze object like Dong Son – styled drums or “Ko” appeared a lot here to the regalia expressing power of the Bigmen (the leaders) in the early historical period in the South of Vietnam and they were just replaced in the early Christian Era under the influence of Indian civilization – process by which French scholars call “Hinduism” and “Buddhism”.

Abstract:
In this paper, I present a short excerpt from an 18-hour-long Bru life history recorded in 1989 in the Central Vietnamese Highlands among the Bru/Vân Kiều of Quảng Trị. The excerpt sheds light on the circumstances of Christian evangelization among the Bru through the recollections of a Bru man who was not Christian himself but was in contact with the key protagonists of the events, the missionaries and the evangelized Bru people. The interview reveals on how the evangelized and non-evangelized viewed the evangelists. What were the ways of promoting evangelization? Were the Bru impressed by the world of the evangelizers? How did the Bru conceive of the evangelizers? How convincing did they find their arguments? Beside its immanent value, this intercultural encounter has a significance beyond itself insofar as it is situated in and reflective of the icy political and ideological milieu of the Vietnam War in the 1960s–1970s, the impacts of which were still lingering when the recording was made.

Những kiến thức bản địa của người Kor có giá trị, cần được duy trì, phát huy và kết hợp với kiến thức khoa học tiên tiến là cơ sở quan trọng cho việc lưu trữ, bảo tồn và cải thiện giống Quế bản địa Trà Bồng trong tương lai. ABSTRACT Tra Bong is one of mountainous districts in the Northwest of Quang Ngai province, where Cinnamon (Cinnamomum cassia BL), a special forestry tree, is distributed naturally with high economic and conservation value. This research aimed to synthesize experience and supplement indigenous knowledge of Kor people in conservation and sustainable development of native Cinnamon species in Tra Bong district of Quang Ngai province. The research has applied PRA method in combination with assessment of cinnamon cultivation models in the field. The research results showed that Kor people have had a lot of experience in recognizing morphological characteristics, selecting mother Cinnamon trees for seeds and planting native Cinnamon in accordance with local real conditions. The valuably indigenous knowledge of Kor people, which needs to be maintained, promoted and combined with advanced scientific knowledge, is an important basis for storing, conserving and improving Tra Bong Cinnamon species in the future.

Abstract:
Purpose – There is currently a debate between NGOs and academia on the effectiveness of training microcredit recipients. One side suggests that merely supplying credit will stimulate entrepreneurial business. The other side proposes that training microcredit recipients in business skills will improve business performance and probably have other important effects. This study was undertaken with the cooperation Vietnam Women’s Union and PeaceTrees Vietnam. The purpose of this paper is to examine the effects of business training programmes for women microcredit recipients in rural areas of Vietnam. Design/methodology/approach – Using a questionnaire administered to 120 women business owners in several communes in Quang Tri Province, data were collected in 2012 on their business training programmes, perceptions of their business performance, motivation, factors for success, and several other indicators. Findings – The findings suggest that business training can improve microenterprise performance and has a number of other positive results, such as increasing motivation, success, and perceptions of entrepreneurs. Research limitations/implications – The research is limited by the nature of the sample and sample size. Future research should focus on women entrepreneurs in other parts of Vietnam, other developing countries, and on male entrepreneurs, to help understand differences between regions, countries, and gender. Originality/value – This paper provides empirical evidence to support the argument that business training is effective in improving the performance of microenterprises.

Abstract:
Ngoc Linh ginseng (Panax vietnamensis Ha et Grushv.) is an endemic species in Vietnam and was discovered at the Ngoc Linh mountain (Kon Tum/Quảng Nam). Investigations showed that the soil with a thick layer of humus was the ideal condition for growth and development of Ngoc Linh ginseng. Therefore research on microbial flora as well as cellulose-degrading bacteria in ginseng soil may elucidate factors contributing to acclimatized cultivation of this ginseng in Vietnam. From the soil sample with cultivated Ngoc Linh ginseng in Quang Nam, five bacteria strains with cellulose-degrading activities were isolated (QN1, QN2, QN3, QN4, QN5 with respectively hydrolyzed CMC halos diameters of 10, 11, 22, 7, 22 mm) with cellulase activities of 1,31; 1,23; 2,99; 0,99; 2,51 U/ml. The combination of 16S rRNA gene sequences and cultured/biochemical characteristics of the bacteria showed that the five bacteria strains was classified to be Pseudomonas sp. QN1; Pseudomonas sp. QN4; Bacillus sp. QN2; Bacillus sp. QN3; Roseomonas sp. QN5.

Abstract:
The process of urbanization in Vietnam is developing rapidly, corresponding to the rapid changes in land use. Forecasting land use development assists policymakers in making accurate decisions in urban planning and development. The objective of this paper is to forecast and analyze land use development trends based on Landsat images in 2006, 2010, and 2016 with the help of remote sensing and GIS, a case study at Gio Linh district, Quang Tri province. The analysis results show that the rapid urbanization in Gio Linh district has led to a rapid decrease in the forest area from 28.14% compared to the total area, in 2016 to 13.5%, in 2026 to 2.67% and 2036 to 0.33%. The forecast processing was done on the neural network built-in module in the Selva version of IDRISI. The accuracy achieved is 80.5%.

Abstract:
This article discusses and analyses the restoration and reorganization of traditional Vietnamese village institutions in Lý Sơn Island, Quảng Ngãi Province since Đổi mới (Reform, 1986). After understanding this topic, we conducted qualitative research on ethnographic field surveys during the intermittent period from March 2008 to August 2019. Our survey results show that the villagers’ self-government organization in Lý Sơn has been cultivated from the beginning of the establishment of the Vietnamese to today, forming a “village – hamlet – neighborhood (sub-hamlet)” hierarchy (làng – thôn – lân). Despite the severe effects of destruction and war, the system is stable and is playing an increasingly important role in maintaining the religious practices of the community. We use Eric Hobsbawm’s concept of “invented tradition” to explain the changes in rural systems, especially the interaction and mediation between tradition preservation and reconstruction to meet the needs of the community and adapt to the specific social environment of each period.
