Emergency Food Security Assessment (EFSA)


An Emergency Food Security Assessment (EFSA) analyses the impact of a crisis on the food security of households and communities. 

An EFSA is conducted when a natural disaster, a conflict or an economic shock causes food insecurity due, for instance, to population displacements. An assessment can be triggered by a sudden event such as an earthquake or a flood or by a slow onset crisis, for example a progressive deterioration of the economic situation. The EFSA can be in the form of an initial (6 to 10 days after the crisis), rapid (3 to 6 weeks after the crisis) or an in-depth (6 to 12 weeks) assessment. 

An EFSA answers the following key questions: Does the crisis have an impact on the population's food security and their livelihoods? How severe is the situation? Has the level of malnutrition been exacerbated by the crisis? How are people coping? How many people are food insecure and where are they? 

An EFSA includes a forecast of how the situation may evolve and an analysis of possible food and non-food responses.
