Abstract
Abstract Although climate-driven hazards have been widely implicated as a key threat to food security in the delta regions of the developing world, the empirical basis of this assertion has centred predominantly on the food availability dimension of food security. Little is known if climatic hazards could affect the food access of delta-resident households and who is likely to be at risk and why. We explored these questions by using the data from a sample of households resident within the Ganges-Brahmaputra-Meghna (GBM) delta in Bangladesh. We used an index-based analytical approach by drawing on the vulnerability and food security literature. We computed separate vulnerability indices for flood, cyclone, and riverbank erosion and assessed their effects on household food access through regression modelling. All three vulnerability types demonstrated significant negative effects on food access; however, only flood vulnerability could significantly reduce a household’s food access below an acceptable threshold. Households that were less dependent on natural resources for their livelihoods – including unskilled day labourers and grocery shop owners – were significantly more likely to have unacceptable level of food access due to floods. Adaptive capacity, measured as a function of household asset endowments, proved more important in explaining food access than the exposure-sensitivity to flood itself. Accordingly, we argue that improving food security in climatic hazard-prone areas of developing country deltas would require moving beyond agriculture or natural resources focus and promoting hazard-specific, all-inclusive and livelihood-focused asset-building interventions. We provide an example of a framework for such interventions and reflect on our analytical approach.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
