Abstract:
Background: The Global Climate Risk Index 2020 ranked Vietnam as the sixth country in the world most affected by climate variability and extreme weather events over the period 1999-2018. Sea level rise and extreme weather events are projected to be more severe in coming decades, which, without additional action, will increase the number of people at risk of climate-sensitive diseases, challenging the health system. This article summaries the results of a health vulnerability and adaptation (V&A) assessment conducted in Vietnam as evidences for development of the National Climate Change Health Adaptation Plan to 2030. Methods: The assessment followed the first 4 steps outlined in the World Health Organization’s Guidelines in conducting “Vulnerability and Adaptation Assessments.” A framework and list of indicators were developed for semi-quantitative assessment for the period 2013 to 2017. Three sets of indicators were selected to assess the level of (1) exposure to climate change and extreme weather events, (2) health sensitivity, and (3) adaptation capacity. The indicators were rated and analyzed using a scoring system from 1 to 5. Results: The results showed that climate-sensitive diseases were common, including dengue fever, diarrheal, influenza, etc, with large burdens of disease that are projected to increase. From 2013 to 2017, the level of “exposure” to climate change–related hazards of the health sector was “high” to “very high,” with an average score from 3.5 to 4.4 (out of 5.0). For “health sensitivity,” the scores decreased from 3.8 in 2013 to 3.5 in 2017, making the overall rating as “high.” For “adaptive capacity,” the scores were from 4.0 to 4.1, which meant adaptive capacity was “very low.” The overall V&A rating in 2013 was “very high risk” (score 4.1) and “high risk” with scores of 3.8 in 2014 and 3.7 in 2015 to 2017. Conclusions: Adaptation actions of the health sector are urgently needed to reduce the vulnerability to climate change in coming decades. Eight adaptation solutions, among recommendations of V&A assessment, were adopted in the National Health Climate Change Adaptation Plan.

Abstract:
The expressway network in Vietnam is developing strongly, playing the role of the backbone of the national road system, in which bridge construction accounts for a large proportion. With many specific characteristics and complex risks always hidden in all stages of the expressway project, risk assessment to have solutions and plans to prevent and respond to risks, limiting the impacts of quality assurance and operational safety of the works is essential. However, the current risk assessment and forecasting models still have many limitations. The application of Machine Learning to all aspects of life is getting more popular. This article develops the algorithms, models and program to assess the technical risks in the period of construction and service of expressway bridges in Vietnam using Machine Learning, in order to solve the current limitations in this work. The selection of key influencing factors is especially important in the field of risk assessment. It improves the classification model's performance by focusing only on the most important factors in the data. Via the applications of artificial neural networks and the Random Forest Algorithm in data processing, the performance risks for bridge management can be analyzed, and performed in more detail and exactly. The possible multiple and non-linear relationships of the risks can be investigated. Based on the results, the proposed model helps the managers to make optimum decisions on managing the risks in advance and to obtain sustainable solutions

Abstract:
Foreign direct investment (FDI) plays an important role in the economic growth of Vietnam, contributing to nearly 22 per cent of the GDP. To attract FDI the government has committed to promoting investment climate and ensuring FDI protection under various international arrangements. FDI inflows into the manufacturing and processing sectors have seen a strong increase after Vietnam’s successful accession to the WTO. However, FDI also contributes to various environmental problems and challenges in Vietnam. From 2008 to 2017, most serious environmental disputes related to manufacturing activities were caused by FDI enterprises. The sanctions against FDI enterprises, however, may jeopardise the state’s responsibilities under investment protection treaties. One of the few realistic approaches to strengthening the environmental management of FDI is to promote the participation of the public in the environmental risk assessment and amend the investment treaties to regulate the issue of environment management. This study will adopt an integrative approach by integrating the rules and principles of environmental management into the FDI regime of Vietnam.

Abstract:
Project performance is assessed using various criteria. Quality is one of the typical triangle criteria used to assess the performance of any office building project. However, office projects in Vietnam have faced numerous quality risks, particularly during their construction periods. This can cause the building projects to be delayed and over budget. As a result, identifying quality risk factors throughout the construction phase of office projects is essential. Therefore, this paper applies the analytical hierarchy process to prioritize critical risk factors affecting project quality during the construction phase of the Biconsi Tower project in Vietnam. The research results show that the five top risk factors affecting the quality of the Biconsi Tower project from most to least impact are as follows: (1) inspection and approval work are not in accordance with regulations and procedures, (2) lack of coordination between project stakeholders, (3) poor quality design documents and drawings, (4) poor construction methods, and (5) poor quality input materials.

Abstract:
This paper aims to find out the relationship between systemic risk in Vietnam and the effects of macroeconomic factors, including exchange rate, interest rates, and economic growth. We collect data from the Vietnamese stock market, specifically 29 listed financial firms (banks, insurance companies, and securities firms) for the period 2010-2018. The analysis is performed in two steps including systematic risk measurement in Vietnam based on the Systemic Expected Shortfall (SES) method and providing evidence from analysis related to the risk determinants assessment. Besides ordinary least squares (OLS) methods, we make use of fixed-effects (FEM) estimations, random-effects (REM) estimations, and system generalized method of moments (SGMM). The empirical evidence in this paper indicates that economic growth has a negative relationship on systemic risk in Vietnam while the exchange rate has a positive impact on systemic risk, and the interest rate has a negative relationship on systemic risk in Vietnam. Future studies can address the effects of interest rate on systemic risk during this period.

Abstract:
Vietnamese farmers are at high risk of pesticide exposure due to usage of pack-back sprays for application of pesticides with their rice crops. Chlorpyirifos has been the most common organophosphate registered for agricultural use in Vietnam, however the health risk due to the use of this compound by rice farmers has not been evaluated. The primary objective of this study was to evaluate the health risk of chlorpyrifos exposure to rice farmers, using a probabilistic approach, with a secondary objective of developing safety strategies for pesticide risk reduction, using qualitative needs assessment methods used for evaluating health promotion programs. Farmer exposure to chlorpyrifos from pesticide application was measured by biological monitoring. Urine samples were collected from farmers (18) over pesticide spraying application time and analysed for 3,5,6-trichloropyridinol (TCP), the major urinary metabolite of chlorpyrifos, using an enzymatic pre-treatment before extraction followed by high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS). Absorbed Daily Doses (ADD) of chlorpyrifos for farmers was then estimated from urinary TCP levels, expressed as μg/g creatinine. The exposure doses, comprising baseline exposure dose (ADDB), post-application exposure dose (ADDA), and lifetime average daily exposure dose (LADDE) were calculated. The baseline exposure dose (ADDB) ranged from 0.03 to 1.98 μg/kg/d with a mean of 0.24 μg/kg/d. The post-application exposure dose (ADDA) ranged from 0.35 to 94 μg/kg/d with a mean of 19.4 μg/kg/d which is approximately 80 times higher than the mean values of ADDB (0.24 μg/kg/d). The lifetime average daily dose (LADDE) ranged from 0.01 to 1.7 μg/kg/d with a mean of 0.3 μg/kg/d. Multivariate regression analysis indicated that personal protective equipment reflected by percentage of body coverage, amount of chlorpyrifos used and length of application made major contributions to ADDA. However, the best regression model for the relationship between ADDA and exposure factors was observed with two independent variables comprising body coverage and amount of chlorpyrifos used.

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.

Nowadays, one of the urgent issues in the management of river basin resources as land degradation, especially soil erosion risk occurs due to complex factors of climate, cultivation practices of human and impacting of the operation of socio-economic development taking place in the basin. Soil erosion has been considered as the primary cause of soil degradation since soil erosion leads to the loss of topsoil and soil organic matters, which are essential for the growing of plants. Ta Trach river watershed, is a mountainous basin lying to the West - South of Thua Thien Hue province, having complex terrain. The result of this study showed that the amount of sediment yield accounts for high percentage. The average annual sedimentation is 41.60 tones per hectometer in the period of 2005 to 2010, soil erosion were classified by 5 levels. In which, the less deleterious erosion level still occupies high percentage with more than 55 % of watershed area. The main area of less deleterious soil erosion was located at high topography and high slope. The area of deleterious soil erosion occupies percentage lower than 22.63% of the entire basin, but it is also a warning sign to the extent of land degradation taking place in the basin if the erosion rate increases in the future

Abstract:
This study assessed environmental health risk from dioxin in foods and sustainability of risk reduction programs at two heavily contaminated former military sites in Vietnam. The study involved 1000 household surveys, analysis of food samples and in-depth discussions with residents and officials. The findings indicate that more than 40 years after the war, local residents still experience high exposure to dioxin if they consume local high risk foods. Public health intervention programs were rated moderately to well sustained. Internal migration, and lack of clear, official guidance and sensitivity regarding dioxin issues were the main challenges for sustainability of prevention programs.

Abstract:
Coastal areas of Southeast Asia are progressively threatened by flooding as a consequence of more frequent precipitation extremes and rising sea levels. Especially urban areas are affected by flood risk which is additionally increased by surface subsidence related to building activities and groundwater extraction. However, the severity of subsidence as well as its triggers and environmental interrelations are only little understood. This study measures surface subsidence for Hue city by using persistent scatterer radar interferometry (PS-InSAR). A series of 53 images acquired by the Sentinel-1 radar satellite between 2018 and 2019 was analyzed to reliably retrieve surface changes at the millimeter scale. The overall displacement ranges between -25 and +10 millimeters per year. Its spatial distribution was then compared to the extent of different soil types in the study area to conduct an analysis of variance (ANOVA). The results confirmed a significant difference between the soil types with Plinthic Acrisols as the soil type having the largest negative average surface velocity. Possible triggers are the intrusion of slack water from the surrounding rice cultivation areas and construction activities which lead to increasing weight and soil compaction. The findings shall raise awareness for the topic and underline the demand for further research.
Mưa lớn và nước biển dâng là những nguyên nhân gây lũ lụt ngày càng nghiêm trọng ở các khu vực ven biển Đông Nam Á. Đặc biệt việc gia tăng công trình xây dựng và khai thác nước ngầm gây sụt lún bề mặt dẫn đến ngập lụt ở các vùng đô thị. Tuy nhiên, các nghiên cứu về mối tương quan giữa sụt lún bề mặt với các hiện tượng môi trường chưa được chú trọng nhiều. Trong nghiên cứu này, độ lún bề mặt của thành phố Hue được đo bằng phương pháp giao thoa radar tán xạ liên tục (PS-InSAR). Phân tích 53 ảnh vệ tinh Sentinel-1 từ năm 2018-2019 cho thấy sự thay đổi tổng thể bề mặt dao động từ -25mm đến 10mm mỗi năm. Phân tích phương sai (ANOVA) cho thấy sự thay đổi bề mặt khác nhau tùy từng loại đất, trong đó đất đỏ vàng (Plinthic Acrisols) có tốc độ sụt lún trung bình cao nhất. Các tác nhân có thể là do sự xâm nhập của nước từ các vùng trồng lúa xung quanh và các hoạt động xây dựng dẫn đến tăng trọng lượng và nén đất. Những phát hiện này là cơ hội nâng cao nhận thức về sự sụt lún bề mặt và cần được nghiên cứu thêm.

Abstract:
AbstractIn this paper we present a conceptual framework for a climate risk assessment based on the so-called impact chains. The method follows a general assessment framework consistent with the IPCC AR5 concept on climate risk. This framework has been developed by Eurac Research within the context of various projects with the German Environment Agency and the German Gesellschaft für Internationale Zusammenarbeit (German Corporation for International Cooperation)—GIZ. It has been applied in almost twenty national climate risk assessments worldwide (e.g., Burundi, Bangladesh, Thailand, Vietnam, Madagascar) and has been perceived as (1) an appropriate means for risk analysis, (2) a useful tool for communication of complex cause-effect relationships in climate change impacts and risks, and (3) a great approach to identify entry points for adaptation measures. For an operational risk assessment, impact chains serve as a basis for the selection of appropriate models, indicators or guide more qualitative, expert-based assessments.

Abstract:
Abstract Coiled Tubing (CT) is a commonly used well intervention technique for sand/debris cleanout, milling, fishing, cementing, and gas lifting applications. Performing cement plug operations with CT in high-pressure live wells can present a relatively high level of risk of getting stuck, improper placement of cement plugs, and poor quality cement plugs. In this scenario, an offshore well in Vietnam was left with CT held only on the surface by the Blow Out Preventers (BOP) after getting stuck downhole more than a year previously. Retrieval of the CT was required without any downhole barrier in place and circumstances that made the conventional killing of the well difficult. This paper will discuss the equipment necessary, factors to consider in the job design, sealant design with lab testing, and describe the technique used to safely retrieve the fish from the well. During the design phase of the solution, risk assessments were carried out to cover various scenarios such as: Poor condition of one or more of the CT string, BOP, dual ball kelly cock valve, double flapper check valve. Inability of the Organic Crosslinked Polymer sealant to hold well pressure. Difficulty in latching the surface CT stump, and the potential requirement for freezing to establish a surface barrier. Along with the specially designed sealant treatment, multiple yard tests for dressing the sheared CT and latching were performed to represent actual conditions during the operation and allow risk mitigation plans to be put in place. Firstly, the barrier verification process was performed to monitor any well pressure build-up from the downhole/surface pressure reading to confirm a barrier was in place, allowing surface equipment to be rigged up. After this was confirmed, the equipment was rigged up, and a fluid circulation test followed by the inflow test of the double flapper check valve in the bottom hole assembly was performed to verify CT integrity. The first of the organic crosslinked polymer was then pumped to plug inside the CT before electric line (E-line) was run into the CT to cut at the free-point above the stuck location. The second organic crosslinked polymer was then placed to plug between the CT and annulus, forming a barrier allowing the makeup of the spoolable connector. Finally, retrieval of the 1,700 meters of CT string took place without any loss of well control. Retrieving the CT from this high pressure well presented a lot of challenges. Achieving a safe and successful operation showed that with proper planning, design, and risk mitigation plans, a potential well control situation can be prevented with the well being secured and successfully returned to production. This paper can now serve as a guideline for future operations with similar circumstances requiring retrieval of stuck CT from high-pressure wells where it has been held on surface for an extended period of time.
