To embark on a sustainable pathwaytoward development, effective policy responses must beimplemented quickly and based on evidence. This requiresreliable, timely data, which is often unavailable especiallyin fragile settings. An innovative High Frequency Survey(HFS) infrastructure offers a modern data collection systemto fill critical data gaps. It can provide quantitative datato inform programs and policies, often linked to resiliencein fragile settings. Using the cases of Somalia and SouthSudan, this note describes the design and setup of such aHFS infrastructure and illustrates how high frequency pricedata can effectively support decision-making even in theevent of an economic or humanitarian crisis.
