Private extreme flood adaptation measures are cost effective and environmentally friendly. The objective of this study is to explore the major adaptation strategies, the determinants of the decisions of households to flood adaptation, specific prophylactic measures, and the constraints of these adaptation measures. A multi-stage sampling technique was employed to select the 337 samples for the study. As the data analysis showed, farm households adopted moving to high elevation places, selling cattle, seasonal migration, flood tolerant rice, planting trees, and the construction of a dike as adaptation measures to flood. The binary logistic regression results from both the socioeconomic and protection motivation theory (PMT) showed that marital status, sex, family size, off-farm income, previous flood experience, access to credit, and the average number of extension visits had a statistically significant positive influence on the flood adaptation decision of households. On the other hand, age, educational attainment, farm size, and access to extension played a negative but statistically insignificant role in flood adaptation decision. The scientific novelty of the paper is that its results revealed that not only the socioeconomic and demographic characteristics of households play a role in the decision-making reactions related to the flood, but also the psychological preparedness of the decision makers. The analysis also drew attention that, due to the mitigation of global influences, in the coming years, households can assume a much more decisive role in the process of local food supply. Therefore, in order to ensure safe supply, climate change-related measures and adaptation strategies must be defined very precisely. Dealing with this phenomenon must be part of social and business innovation as it can cause not only food supply problems but also various migration effects, which, in the short term, would result in the most serious damage to the social system.

The Vietnamese Mekong Delta (VMD) is one of the largest rice-growing areas in Vietnam, and exports a huge amount of rice products to destinations around the world. Multi-dike protection systems have been built to prevent flooding, and have supported agricultural intensification since the early 1990s. Semi-dike and full-dike systems have been used to grow double and triple rice, respectively. Only a small number of studies have been conducted to evaluate the water quality in the VMD. This study aimed to analyze the spatiotemporal variation of water quality inside the dike-protected area. Surface water samples were collected in the dry and wet seasons at 35 locations. We used multivariate statistical analyses to examine various water quality parameters. The mean concentrations of COD, NH₄⁺, NO₃⁻, PO₄³⁻, EC, and turbidity were significantly higher in water samples inside the full-dike system than in water samples from outside the full-dike systems and inside the semi-dike systems in both seasons. High concentrations of PO₄³⁻ were detected in most of the primary canals along which residential, tourist areas and local markets were settled. However, NO₃⁻ was mainly found to be higher in secondary canals, where chemical fertilizers were used for rice intensification inside the dike system. Water control infrastructures are useful for preventing flood hazards. However, this has an adverse effect on maintaining water quality in the study area. Full article
