This is the 29th monthly Knowledge, Evidence and Learning for Development (K4D) Programme’s Humanitarian Evidence Summary (HUMES), signposting to the latest relevant evidence and discourse on humanitarian action to inform and support their response. It is the result of one day of work per month and is not intended to be a comprehensive summary of available evidence on humanitarian action but aims to make original documents easily accessible to decision-makers that, if relevant to them, they could refer to before making decisions.
