Chapter 5 greater are the effects as described above. If world market prices were above the domestic market price, no commercial food imports would take place under free market conditions. There are further factors and conditions governing the level of domestic prices, import prices and the volume of food imports, and determining the extent to which the effects described above take place. This refers, for example, to the following issues: 1) The exchange rate (see section 3.3 of Chapter 4 and Annex 2B); 2) Government market and price interventions (see section 7 of Chapter 4); 3) Concessional (food aid) imports, implying lower import prices compared to commercial imports (this issue will be discussed in detail in Chapter 6), and: 4) The uses of food aid. Food aid supplies can be used, for example: to build up food stocks/security reserves (see section 2.2.2 above); to increase general market supplies, by feeding the food aid deliveries into normal market channels to sell them at normal market prices. (Typical approach to programme food aid, see Chapter 6. The effects are as described above); for specific food and nutrition interventions, aimed at improving the consumption of those who, due to poverty or other reasons, have insufficient access to the food they need. This refers for example to targeted food subsidies, emergency relief, feeding programmes for vulnerable groups, food for work schemes, etc. Such approaches are discussed in the following section. 3. Improving Access to Food 3.1 Access to food on national and household levels Often the crucial food problem does not consist of a general shortage in the volume of food production and supplies but in insufficient access to the food which is available on the market or which would be produced and made available if absorbed by effective demand (see the important link between food demand and food markets in Figure 4-2, Chapter 4). A precondition for food security is, therefore, not only the availability of adequate and reliable food supplies but also sufficient access to food supplies for the household to meet their requirements. The importance of access to food as the other essential precondition of food security was emphasized at the World Food Summit and is reflected in the Commitment number two "We will implement policies aimed at eradicating poverty and inequality and improving physical and economic access by all, at all times, to sufficient, nutritionally adequate and safe food and its effective utilisation" (see Chapter 6, section 5). Access to adequate food as a prerequisite for food security applies to the national as well as the individual household level. - 199-
