Chapter 5 economy: Supply based approaches will have indirect effects on food demand (e.g. through income changes of the producers or the real income effect of price changes), and vice versa. Furthermore, in order to be effective and sustainable, increased food supplies need to be absorbed by increased demand. On the other side, increased demand must be met by increased supplies, otherwise food prices will rise and offset any gain. Whether food security can be enhanced more effectively by supply or by demand based approaches depends also on the predominant types of food deficits in a particular country or area of concern: in countries or areas where temporary or structural production/supply deficits are the predominant problem (e.g. due to insufficient market production and scarcity of foreign exchange to pay for food imports), there is a priority need for supply based approaches (Fig. 5.1 a). In cases where, due to wide-spread poverty, demand deficits are the main issue of concern (Fig. 5.1 b), policy measures must be primarily geared towards employment and income generation or other measures to promote access to food of the vulnerable groups.

Its prior review will facilitate comprehension of the further analytical steps. - 186-
