Chapter 6 1) The local purchase potential which is determined by the marketable surpluses available in a country or region which can be absorbed by local purchases without disturbing the local food market. Close market and price monitoring is required to assess such potential, in order to avoid severe market distortions that may occur if local purchases exceed available market supplies. It appears, however, realistic to assume that such market potentials can be gradually developed by repeated local purchase operations in the same areas (demand induced expansion of local marked production). An already widely applied alternative, incorporating most of the advantages of local purchases mentioned above, consists in so-called triangular or trilateral transactions, specifically if neighboring countries or countries belonging to the same region as the recipient countries are involved. Triangular transactions function according to the following principle: Figure 6.3: Triangular transactions in food aid Donor country Food aid Fin ial co itment flow Recipient country < Commodity flow Procurement country 2) The funding requirements for local purchases. While food aid deliveries from surplus producing countries are often additional to other development aid, local purchases require additional and specifically allocated financial resources. This is likely to limit the potential scope for local purchases. In spite of such limitations, the share of food aid procured in developing countries has substantially increased in recent years, reaching 16.2 percent of all food aid deliveries in 1995 (see Table 6.1). About 70 percent of the commodities were procured in a third country through triangular or trilateral transaction and 30 percent through local purchases in the recipient country itself. 2.6 Evaluating and improving the efficacy of food aid interventions For an assessment of the efficacy of food aid interventions in enhancing food security, various aspects have to be taken into account. These are in summary: * The objectives of the food aid interventions: improving food security (mitigating acute food shortages, transitory, chronic food insecurity), foreign exchange support, budgetary support, compatibility of objectives of donors and the recipient country, distinction between short-run and long-term objectives. -238-
