The GNC/GTWG has just published interim guidance for wasting programming in resource-constrained contexts:

https://www.nutritioncluster.net/resources/interim-programmatic-adaptations-wasting-programming-resource-constrained-settings

Please note: As outlined in the document, these adaptations are intended to serve as temporary and exceptional measures and should be agreed upon via coordination mechanisms and inclusive dialogue with relevant authorities. They are interested to hear from implementers on any feedback and/or documentation of those adaptations.
