“…Second, Hoan, Khoi, and Trung (2019) assess the adaptive capacity of farmers towards saline intrusion in different saline environments in the Vietnamese Mekong Delta. This study could help managers and policy-makers to propose appropriate and feasible options in a 'bottom-up' approach for the adaptation plan to guarantee sustainable livelihoods for the local farmers.…”

“…Many studies have focused on the determinants of farmers' adaptation to climate change in the VMD from different perspectives. Critical factors influencing farmer behavior and adaptive capacity may include financial ability (budget, resources), technical proficiency (technique, knowledge, skills) and institutional power (social organization, market) (Hoan et al , 2019; Brown et al , 2018). Meanwhile, many scholars such as Luu et al (2019), Ho and Shimada (2019), Nguyen et al (2019) and Dang et al (2014a, b) found a positive relationship between farmers' perception of climate risks and their willingness to adapt.…”

“…Key determinants include expected profit or loss prevention (Kumar et al , 2018; Tran et al , 2018a; Luu et al , 2019; Joffre et al , 2015); peer influence (Dang et al , 2014a); and information sharing via informal channels and formal channels (Luu et al , 2019; Ho and Shimada, 2019; Trinh et al , 2018). Moreover, some studies indicated that farmers tended to adjust their farming systems based on their accumulated experience in specific biophysical conditions such as land quality, land suitability, flood and salinity level (Tri et al , 2019; Hoan et al , 2019).…”

PurposeThe Vietnamese Mekong River Delta (VMD) is one of the most affected deltas by climate change in the world. Several studies have investigated factors influencing farmers' climate change adaptation behaviors in the region; however, little is known about the effectiveness of such measures. This paper examines the determinants of adaptation strategies among VMD rice farmers and assesses the impacts of such practices on rice yield.Design/methodology/approachEndogenous switching regressions were employed using a survey data of 300 rice-producing households in An Giang and Tra Vinh provinces in 2016.FindingsThe results show that farmers receiving early disaster warnings are more likely to adopt adaptation measures to climate change. If nonadaptors had chosen to respond, their rice yield would have increased by 0.932 tons/ha/season.Research limitations/implicationsThe data sample is small and collected from two provinces in the VMD only; therefore, the results may be specific for the study sites. However, future research can adopt the proposed method for other regions.Originality/valueThe study estimates the production impacts of farmers' decisions on whether or not to adapt to extreme climate events. The proposed approach allows for capturing both observed and unobserved behaviors.

“…However, the VMD is a flat lowland with dense river system and is influenced by the tides of the East Sea and the West Sea. The VMD is very vulnerable and always faced with saline intrusion disaster [4][5][6], especially during the dry season from January to May when the upstream flow is low. Recently, the saline intrusion had complicated with the fluctuations of upstream flows, climate change and SLR, it made more difficult for fresh water supply in the VMD.…”

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.
