Book excerpt: The COVID-19 pandemic resulted in severe income losses, but little is known about its impacts on diets and nutritional adequacy, or the effectiveness of social protection interventions in mitigating dietary and nutritional impacts. We first assess the likely impacts of COVID-19 shocks in Bangladesh and Myanmar on poverty and food and nutrient consumption gaps. We then analyze the estimated mitigating effects of five hypothetical social protection interventions of a typical monetary value: (1) cash transfers; (2) in-kind transfers of common rice; (3) in-kind transfers of fortified rice enriched with multiple essential micronutrients; (4) vouchers for a diversified basket of rice and non-staple foods; and (5) food vouchers with fortified rice instead of common rice. The simulation results suggest modest effectiveness of the cash transfers for mitigating poverty increases and little effectiveness of all five transfers for preventing increasing food and nutrient consumption gaps among the poorest 40%. Rice fortification is, however, effective at closing key micronutrient consumption gaps and could be a suitable policy instrument for averting ‘hidden hunger’ during economic crises.
