The Modality Decision Tool (MDT) Nutrition Addendum aids implementing partners to apply a nutrition lens to the selection of appropriate food assistance modalities (cash, vouchers, or in-kind) for the nutritionally vulnerable. This addendum is primarily oriented to USAID/BHA's "supplemental nutrition sub-sector" under their emergency activity guidance, but will also be applicable to resilience food security activities that provide a resource transfer to nutritionally vulnerable populations.
