The potential for mitigation of CO2 emissions in Vietnam's power sector
No full textThis manuscript examines CO2 emissions from Vietnam's power sector using an expanded Integrated Resource Planning model. The potential effects of the following alternative policy options are examined: energy efficiency, favorably imported generation fuels, nuclear energy, renewable energy, and an internalized positive carbon value. The baseline in terms of cumulative CO2 emissions over 2010-2030 is 3.6 Gt. Lighting energy efficiency improvements offers 14% of no-regret abatement of CO2 emissions. Developing nuclear and renewable energy could help meet the challenges of the increases in electricity demand, the dependence on imported fuels for electricity generation in the context of carbon constraints applied in a developing country. When CO2 costs increase from 1 /t, building 10 GW of nuclear generation capacity implies an increase in abatement levels from 24% to 46%. Using renewable energy abates CO2 levels by between 14% and 46%. At 2 /tCO2, the model predicts an abatement of 1.4 Gt when efficient gas plants are substituted for coal generation and when the potential for wind energy is economically developed further than in the former model.integrated resource planning, carbon value, abatement of CO2 emissions, Vietnam, electricity generation
Impact of Participatory Irrigation Management (PIM) to Local Communities and Environment in Hop Tien Commune, Dong Hy
No full textThis case-study is designed to support the development of the Viet Nam – Netherlands Water Partnership on Water for Food and Ecosystems. The partnership is between Viet Nam’s Ministry of Agriculture and Rural Development (MARD) and the Netherlands Ministry of Agriculture, Nature and Food Quality (LNV). IUCN has been asked to coordinate the Partnership development process, including through undertaking study that will identify strategies for the management of water resources that balance agricultural production with the maintenance of the integrity of critical ecosystems that depend on adequate water flows. The case study is being carried out in Hop Tien commune, Dong Hy district, Thai Nguyen province, Vietnam. The purpose of the case study is to identify mechanisms based on that water resources management, which are traditionally approached as single purpose management regimes, should be enhanced to become more integrated, multi-stakeholder based management systems. At the irrigation scheme level, water resources management is considered as irrigation governance and management. The integrated approach is carried out with considerations of various interests such as irrigation, domestic water supply and fishery in Hop Tien commune. On the other hand, issues of saving water, water resources protection should be paid attention in the case study to ensure sustainable water resources development in the area

Description. Female. Body length 11–12 mm (holotype 11.5 mm); fore wing length 10–11 mm (holotype 10.5 mm). Structure as in Eumenes longus sp. nov., but differs as follows. Head in frontal view slightly wider than high (Fig. 7). Distance between inner eye margins (frontal view) at vertex twice more than at clypeus. Clypeus nearly 1.8 × as highas wide (Fig. 7). Metasomal segment 1 in dorsal view gradually widened from base to apex (Fig. 9), tergum and sternum fused, suture between them distinct almost throughout basal part. T 2 in lateral view as long as wide (Fig. 8). Body with slightly less coarse punctures than in E. longus. Color. Black, with following parts yellow: narrow band along inner eye margin extending from bottom to near ocular sinus, spot between antennal sockets, short line at vertex behind eye, short line at basal margin of dorsal pronotum, apical part of parategula and apical margin of T 1. Legs black. Propodeal valvulae dark brown. Wings dark brown, strongly infuscate, veins dark brown. Male. Body length 10–11 mm; fore wing length 9–10 mm. Structure as in female and male of E. longus but clypeus proportionally longer, in frontal view 2.3 × as long as wide, with sharper teeth (Fig. 10). F 11 propotionaly shorter than in E. longus (Fig. 11). Color as in female. Distribution. Northern Vietnam: Tuyen Quang, Ha Giang, Bac Kan, Thai Nguyen, Son La, Vinh Phuc, Ha Noi, Thanh Hoa, Nghe An. Etymology. The specific name refers to the similarity with its congener E. longus. Remarks. This species is similar to E. longus, but can be easily distinguished from the latter by having T 1 gradually widened from base to apex (gradually widened basally and then parallel in E. longus), T 2 in lateral view as long as wide (1.1 × as long as wide in E. longus), and male clypeus with sharper teeth. This species can be distinguished from two Papuan species by having clypeus nearly 1.8 × as high as wide (less than 1.3 × as high as wide in two Papuan species).Published as part of Nguyen, Lien Thi Phuong, 2016, Two new species of the genus Eumenes Latreille, 1802 (Hymenoptera: Vespidae, Eumeninae) from Vietnam, pp. 583-588 in Zootaxa 4093 (4) on pages 585-587, DOI: 10.11646/zootaxa.4093.4.11, http://zenodo.org/record/27097
Suggestions for improvement in Vietnam employment laws in the context of gender equality
No full text5 p.Improving gender equality in the workplace is an urgent task for Vietnam Communist Party and the Government. Despite the ratification of international conventions on labour, women rights, as well as amendment to relevant domestic laws, it appears that the provisions have not satisfied the requirements set forth to combat discrimination at work against women. Through this article, the author intends to propose some ideas to improve the laws on the protection of the current female workers’ rights based on the 2012 Labour Code (amended and supplemented in 2019), related laws and sub–law documents
Citizen's Satisfaction With Public Administrative Services At The One-Stop Shop Of Districts In Thai Nguyen Province, Viet Nam
No full textThe research was conducted to determine the factors affecting Citizens's satisfaction with public administrative services in the one-stop department of districts in Thai Nguyen Province. The study is based on the survey data of 324 citizens. Data analysis method through SPSS software with descriptive statistical tools, test scale with Cronbach alpha coefficients, discovery factor analysis (EFA) and Regression analysis was performed to clarify the problems related to the research hypothesis. The Regression model consisting of six variables: Capacity of civil servants, Service attitude of civil servants, Facilities, Work assignment process, Time and Cost is used to identify the factors that affect Citizens's satisfaction. The research results show that the variables in the model have a positive relationship with Citizens's satisfaction. In particular, the Capacity of civil servant factor has the highest Beta coefficient of 0.303. From the research results, the author also proposed a number of solutions to improve the satisfaction of citizens at the One-stop shop of districts in Thai Nguyen Provinc
