Abstract: The article is based on data from the research program "Greater Mekong Subregion Flood and Drought Risk Management and Mitigation Project (ADB-GMS1)" jointly implemented by the Asian Development Bank (ADB) and the Ministry of Agriculture and Rural Development, and the Vietnam Institute of Water Resourches Research in Tien Giang and Dong Thap province. The results show that, in recent years, due to the increasingly severe global climate change, the intensity of various types of natural disasters occurs more frequently, irregularly and with greater intensity. This has greatly affected the production, daily life and properties of the people in the vulnerable areas. To reduce the impact of various types of disasters on people living in vulnerable areas, it is necessary to combine two types of solutions in disaster prevention, namely construction solutions and non- construction solutions. In which, non-construction solutions play a very important role, namely, people living in communities are considered as the main actors in preventing and mitigating disaster risks occurring in the community.
Research results show that compost was created at the rate of C / N: 25/1 by mixing ingredients 2.5 grams of cow manure, 3g of organic waste, 0.01g of coir based on calculation of content. C and N in each material; With the humidity of 60% based on the calculation of the moisture content from the compost materials combined with the amount of water to add is 670ml, from which a Compost fertilizer has been produced. Determination of the optimal values for the mixratio and function has been verified on experimental crops. Research also shows that the use of probiotics in composting will shorten the compost time, limit the odor escaping from the compost.
Performance-related pay (PRP) is an integral part of Reward Management (RM) and is considered to have beneficial effects on organisational performance and employee motivation. Drawing on 14 case studies, this paper examines the Reward Management practices of local and multinational companies in Australia with specific consideration to PRP within the debate over the applicability of the transfer of the Human Resource Management (HRM) practices between nations through subsidiary-parent company relationships. After reviewing the relevant literature(s), the study concentrates on finding whether multinational corporations (MNC) in Australia pursue similar or different RM practices compared to their domestically owned Australian counterparts with special reference to PRP. It also investigates whether there are national variations between multinational companies in terms of the nature and character of their practices. The findings reveal country of origin differences in the way PRP practices are applied in subsidiaries of foreign-owned companies in Australia and local Australian firms. The case studies are used to examine and explain the practices.
Chau Pha Lake is one of the large reservoirs providing water for domestic, irrigation and production of people in Phu My town, Ba Ria Vung Tau province. This study was conducted to analyze the parameters of pH, temperature, DO, BOD5, COD, N-NH4+, P-PO43-, TSS, turbidity, total Coliform on 16 samples in 2020 and the water quality index calculation WQI. The analysis results show that the water quality of Chau Pha lake in the rainy season is quite good, all parameters reach the limit value A2 according to QCVN 08:2015/BTNMT; however, in the dry season, the values of parameters DO, BOD5, P-PO43, TSS exceed the limit value A2 but not significantly; WQI values fluctuate at a fairly high level from 71 to 92, which is correlated with turbidity, COD, and BOD5 parameters. Thus, the average WQI of the lake reaches 85.4 points, corresponding to level 2 (green) - water used for domestic water supply purposes but needs appropriate treatment measures.
