Approaches to food security assessments

Answers

a) Early warning and surveillance approaches
This form of assessment depends on the continuous collection and interpretation of information.
Many early warning systems and surveillance systems have been set up at country, regional and
international levels. Systems rely heavily on secondary data (information already collected by
another agency), which come mainly from national government statistics on rainfall, crop
production, prices and imports/exports and from satellite imagery. Such systems have generally
been successful in predicting impending food crises, although not as accurate at pinpointing
exactly when a crisis is likely to occur.
b) Economic and livelihoods approaches
These approaches view food security within a broad economic or livelihoods (means of living)
context. One-time surveys are usually carried out and information collected on a variety of
indicators both quantitative (based on amounts or numbers) and qualitative (based on qualities or opinions). The information is used to estimate the household food deficit and to project what the deficit may be in the future.
c) Nutritional status approaches
Food security has an indirect effect on nutritional status and is one element that is assessed along with other factors that impact on nutritional status. Nutritional status approaches tend to be one- time surveys that collect a variety of information.
