Application of Different Evapotranspiration Models to Calculate Total Agricultural Water Demand in a Tropical Region

Today, water in the Long Xuyen Quadrangle-An Giang (LXQAG)(Mekong River delta, Vietnam) is becoming scarce in some seasonsand some districts in the region, especially when the scenariosof climate change will affect water resources in the future.Therefore, it is necessary to make decisions about water conservationand distribution to ensure compatibility with the socialobjectives such as economic efficiency, sustainability and fairness.The mathematical models used for water distribution andbalance calculations are the prominent themes nowadays. To performthis task, it needs to calculate the water needs for all economicsectors. In this article we are particularly concerned aboutwater demand calculation methods for crops and aquaculture.Because these are the two main commodities accounting for thehighest water usage in the region. Water demand for crops is calculatedthrough potential evaporation using the methods of Hargreaves& Samani; Priestley and Taylor and Penman-Monteithto check if the first two simpler methods with less data demandcould be used to estimate evapotranspiration. The results showthat the simpler methods were significantly different and thereforewater demand calculations must be based on the Penman-Monteith method for the water demand of crops and the methodsof Penman to calculate expansion evaporation for aquaculture.The result shows that the total water demand in 2015 is 6,428million m3/year. It is estimated that in 2020, agricultural waterdemand will rise by 71% compared to 2015 to 22,531 millionm3/year. The main reason for this rise is that the local managersexpect the catfish farming area to increase by 80%, if peopleapply the “VietGAP standards”

Plastic Waste Generation and Management in Thoi Lai District, Can Tho City, Vietnam

The objective of this study was to assess the current situation of generation and management of plastic waste in Thoi Lai district, Can Tho city, Vietnam through collecting domestic solid waste samples from 30 households and interviewing 150 households using questionaires. The results showed that the average amount of domestic solid waste was 0.3 kg/person/day, in which the plastic waste accounted for 11.7% with generation rate of 0.035 kg/person/day. Shopping bags were dominant accounting for 34.7%, single-use plastic products accounting for 18.5% and food packaging plastic bags accounting for 9.51%. The generation rates of domestic solid waste and plastic waste had positive correlation with household’s size and income. In addition, the rate of plastic waste generation also appeared to have a relationship with the characteristics of the study area. Plastic waste has not been classified but it is mixed with other domestic solid waste. Knowledge of plastic waste impact has not been widely propagated in the community. Therefore, appropriate measures should be implemented to reduce municipal waste and plastic wastes

The Impact of Oil Price on the Growth, Inflation, Unemployment and Budget Deficit of Vietnam

In oil exporting countries, especially OPEC members, oil price fluctuation has significant impacts on their economies. Herein, just a drop in the oil price causes directly many adverse effects, such as inflation, falls in economic growth, and increases in unemployment. However with a country which not only exports crude oil but also imports petroleum as Vietnam, it is not easy to determine falling or a rising oil prices is beneficial to the economy. Therefore, this paper aims to carry out a numerical analysis on the influences of oil prices on the macroeconomic variables of Vietnam, including inflation, growth rate, budget deficit and unemployment, during a period from 2000 to 2015. By using a vector auto regression (VAR) model, it is realized that a rise in oil prices would lead to higher inflation and budget deficit in Vietnam while its impacts on the GDP growth and unemployment are unclear.

Educating and training labor force Under Covid 19; Impacts to Meet Market Demand in Vietnam during Globalization and Integration Era

During integration and globalization era, Vietnam labor market face challenges but also have lots of opportunities. This paper mainly use qualitative analysis with statistics, synthesis and inductive methods, combine with dialectical materialism methods. Research results indicate that because many Vietnam laborers do not have enough work skills and lack of training programs, they meet difficulties on job; hence, human resource management need to deal with issues of improving skills and knowledge for workforce to meet demand under EVFTA and Industry 4.0. There are lots of job opportunities from banking, finance to manufacturing, industries. Last but not least, this study also propose some solutions to deal with challenges in Human resources to meet demand from corporations. For instance, we need to invest more on equipment and infrastructures, as well as quality of trainers for human resources of training schools, so that Vietnam businesses can overcome challenges from EVFTA

From Negative Aspects and Black Aspects of Vietnam Education to Lessons for Social Sciences Students

In our research, we level strong criticism at the State Professor Council in Vietnam, using the case of Tran Van Tho and other members as a representative illustration of their efforts to impede or restrict the growth of the nation's scientific community. We also do not place enough importance on the publication of bogus news online by various Vietnam publications (Thanhnien.vn and Tuoitre.vn), despite the fact that it may lead to confusion, as well as problems and concern in the community. In addition, we oppose the excessive tuition fees and other expenses that have been imposed by Banking University HCM city Vietnam and other institutions in HCM city in recent years, which have caused difficulties for families, parents, students, and society as a whole. In addition, we use these problematic aspects of the education system in Vietnam as a case study to instruct students majoring in social sciences. After that, the authors apply a strategy based on the laws of Malaysia in order to solve the problem of fake news published in the newspapers tuoi tre and thanh nien in Vietnam throughout the period 2015-2022. After the case discussion that was offered earlier, the authors assess the opinions of President Ho Chi Minh on publishing activities for the purpose of better teaching pupils. This is not the least of the authors' contributions
