Making exchange entitlements operational: the food economy approach to famine prediction and the RiskMap computer program.
The effect of production failure or some other shock on household income and food supply depends upon: (a) the pattern of household income, and (b) its ability to compensate for any deficit which may have occurred, for example, by the sale of assets or finding additional paid employment. The corollary is that the prediction of the likely effect of some event on the future state of the economy or food supply of a population of households requires an understanding of the economy of the households concerned and the economic context to which these relate. This paper describes an attempt to develop an approach to prediction using a dynamic model of economy based on quantitative descriptions of household economy obtained by systematic rapid field-work and summarises the experience of the use of this approach to date.
