This study quantifies the cost and time benefits of a large and diversified investment “portfolio” of emergency preparedness interventions undertaken by UNICEF and WFP in 2014 with support from the United Kingdom’s Department for International Development (DFID). A return on investment model is applied to 49 emergency preparedness investments in three pilot countries: Chad, Pakistan and Madagascar, and investments span across four main operational areas logistics, procurement, staffing and partnerships/ external contracting.
