“…Gần [3,16]. Do vị trí địa lý nằm hạ lưu sông Mekong nên chế độ thủy động lực của BĐCM chịu sự tác động của dòng chảy từ thượng nguồn sông Mekong và chế độ bán nhật triều Biển Đông, nhật triều từ Biển Tây [3,[17][18]. Nằm trong khu vực nhiệt đới gió mùa, BĐCM chịu sự chi phối của hai mùa gió Đông Bắc và Tây Nam, mưa trung bình hàng năm của khu vực cao hơn so với các khu vực khác của Việt Nam và 90% lượng mưa năm tập trung vào mùa mưa [19].…”

In recent years, heavy rainfall events have appeared frequently in the Ca Mau peninsula area, causing local flooding and affecting many aspects of life in the area. According to a report of the Ministry of Natural Resources and Environment, rainfall is an increase tend in intensity and frequency in the Ca Mau Peninsula as a part of climate variability. Heavy rainfall tends increase, which will cause the local flooding events in which has low terrain and less severe drainage systems. It is, thus, necessary to proactively prevent adverse effects from flooding events on people's lives. Therefore, the goal of the study is a) to simulate rainfall intensity-duration-frequency (IDF) curve of the extreme rainfall events using the CumFreq software for the Ca Mau Peninsula and b) toward to establish inundation maps based on the simulated data from rainfall IDF curve, contributing to proactively minimize the potential risks of flooding as well as proactively adapt the impacts of climate variability.

“…Shifts in agricultural practices are proposed to overcome the negative effect of seawater intrusion. The use of salt-tolerable crops, implementing hard-structures to prevent salt diffusion, utilizing advance cultivation techniques and conveying freshwater into agricultural subsystem are appropriate alternatives [85]. Hybrid FO fertigation and microalgae dewatering is proposed as an advanced cultivation technique, as schemed in Figure 4.…”

Microalgae in Food-Energy-Water Nexus: A Review on Progress of Forward Osmosis Applications

Nowadays the world is facing vulnerability problems related to food, energy and water demands. The challenges in those subsystems are intertwined and thus require inter-discipline approaches to address them. Bioresources offer promising solutions of the dilemma. Microalgae biomass is expected to become a superfood and a favorable energy feedstock and assist in supplying clean water and treat wastewater. Efficient mass production of microalgae, both during upstream and downstream processes, is thus a key process for providing high quality and affordable microalgae biomass. This paper covers recent progress in microalgae harvesting and dewatering by using osmotic driven membrane process, i.e., forward osmosis. Critical factors during forward osmosis process for microalgae harvesting and dewatering are discussed. Finally, perspective on further research directions and implementation scenarios of the forward osmosis are also provided.

“…The saline intrusion in the VMD under the impacts of upstream flows, climate change and SLR has been presented in previous studies [5,6,[9][10][11][12][13][14]. They have indicated that the impacts of climate change, SLR and upstream flow changes increased the saline intrusion and negative impacts on water supply and agricultural products.…”

Saline intrusion is a hot issue and has always been of concern in the VMD (Vietnamese Mekong Delta), especially in the context of many changes of impact factors such as upstream flows and SLR (Sea Levels Rise). Vulnerability to changes in the upstream flows and SLR ismust-have reasons for updated and interpreted information. This information is used for exploiting of soil and water resources. MIKE 11 model was successfully applied to assess the saline intrusion. The study provided the picture of the saline intrusion in the dry season from January to May in the VMD in the existing situation (2015 and 2016) and the future (2030 and 2050) under the impact of flow at Kratie in various frequencies of 18%, 50% and 85% based on the time series of 2001-2016, and SLR according to RCP (Representative Concentration Pathway) 4.5 scenario of MONRE (Ministry of Natural Resources and Environment) of Vietnam issued in 2016. The results show that in the year 2015 the ASI (Saline Intrusion Area) in the VMD was relatively low due to moderate tidal level and high Kratie discharge (P = 18%). The scenario like the situation in 2016 and in the future ASI increased significantly compared to the 2015 baseline scenario which shows that the VMD is very vulnerable to saline intrusion. Based on multivariate regression analysis, the study also presented the formulas for the relationship between the ASI of 0.25 g/L, 2.5 g/L and 4.0 g/L thresholds and the impact factors such as the average discharge at Kratie and the maximum daily tidal level in East Coast during the dry season from January to May. With an adjusted R 2 at 0.913-0.974, these formulas are believed to be reliable for predicting ASIs based on the Kratie flow and the East Coast tidal level.
