chapterr 5 The preceding discussion has already revealed the close linkages which exist between price stabilisation and stocking policies: building-up of food stocks means increased market demand and has the effect of stabilising prices from falling below desired levels in times of abundant supplies, while a release of food stocks means increased market supplies and prevents prices from rising exorbitantly when market supplies are scarce. There are two exceptions to this general rule: 1) if stocks are built-up with food imports, there is no additional market demand and no price effect on the domestic market when stocks are built-up, and 2) if stocks are released via free food distribution to the poor, the volume of market supplies and the market prices will not be affected to the full extent of the stock release. In the latter case there may be indirect effects, if the beneficiaries of free food rations reduce their market demand for food, or if they sell part of the free food rations on the market. (Such phenomena are related to the issue of targeted assistance being addressed further below.) In establishing targets for the size of public food stocks, a compromise has to be found between the objective of maximising supply stability and food security, and minimising costs and budgetary burdens. The costs of public stockholdings are quite substantial and are seldom covered by the marketing margins, as indicated above. In defining optimal stocking levels for public food reserves, a number of different factors have to be taken into consideration, such as: * Production and supply risks, depending, for example, on the drought proneness of a country, the prevailing production systems (e.g. rain-fed versus irrigated agriculture), civil disorder, etc. * External supply routes for food imports: countries with easy access to external markets will have lower storage requirements than, for example, land-locked countries, countries with insufficient port facilities, or areas which are cut off from external markets for geographical, political or economic reasons. * The quality of the internal transport infrastructure determines the effectiveness and efficiency of internal transfers between (potential) surplus and deficit regions. * Private stocks held, for example, by farmers, traders or households, and the interrelationship between private and public stockpiling practices. Private stocks will reduce the need for public security reserves. The interaction between private and public stocking practices depends largely on: * The established marketing system: the role of public sector and private agencies in food marketing, pricing and marketing policies pursued by the government, and the efficiency of the marketing system. (The case of pan-seasonal pricing policies discouraging private stockholding has already been addressed in section 7.2 of Chapter 4.) - 196-
