| Sumario: | This technical report presents the findings of a partnership between the Alliance of Bioversity International and CIAT (The Alliance, a CGIAR research center) and the Vietnam Ministry of Health’s National Institute of Nutrition (NIN) to examine the linkages between climate change, human mobility, and household food and nutrition security (FNS) outcomes in the Mekong Delta. Following the co-development a climate-related mobility survey questionnaire that was added to the 2024 National Nutrition Surveillance (NNS) in Bạc Liêu province, this report provides initial analysis to support research, policy development, and programming strategies in climate-vulnerable, high out-migration areas in southern Vietnam.
Key results include:
• Climate-related hazards are associated with negative FNS outcomes, including food insecurity (FI), child malnutrition, and negative infant and young child feeding practices (IYCF), with diverse and nuanced impacts for both slow- and fast-onset climate hazards.
• Remittances mitigate FNS risks, especially in households exposed to climate-related hazards, as increased remittance values correlate with reductions in child stunting and small body mass index (small BMI).
• Children in households with migrant mothers face higher stunting rates, highlighting caregiving challenges despite financial support.
• Larger households experience greater food insecurity (FI) and lower minimum meal frequency (MMF) likely due to resource dilution.
• Households classified as part of the Hoa and Khơ-me ethnic minorities have higher food insecurity (FI) and lower minimum dietary diversity (MDD), reflecting systemic inequalities among migrant-sending households.
• Infant and young child feeding (IYCF) indicators present mixed results, indicating complex influences under climate and migration stress.
