Chapter 6 Figure 6.1 depicts the situation of an overall aggregate food deficit in a country, composed of a market supply/import deficit (C-B) and an aggregate demand deficit (D-C). It applies to an open economy, with p indicating the level of world market prices (border price expressed in local currency units, see Annex 2B for explanation).

R-B: Demand deficit: Need/scope for project and/or relief food aid for targeted distribution of food to those people who lack the purchasing power to express their food needs as effective demand. R-A: Total aggregate (structural) food deficit: Needs to be covered by imports (commercial imports, programme food to be monetised, and project/relief food aid according to the proportion of the sub-deficits) in order to meet total requirements and to achieve food security. 2.5.1 Programme food aid to mitigate market supply deficits A market supply/import deficit (B-A) determines the potential scope for programme food aid to the extent that programme food aid deliveries substitute for commercial food imports. Such a substitution is desirable or necessary if a country is short of foreign exchange. Programme food aid has, in this case, the main function of foreign exchange support. As the effective demand for food exceeds domestic production and market supplies, food (aid) imports can be monetised up to the amount of a prevailing deficit, without the risk of market - 232 -
