Attaining food security in Central Asia—emerging issues and challenges for policy research

Developing long-term strategies for improving food security, alleviating poverty and encouraging sound use of natural resources is fundamental for sustained economic growth in Central Asia. However, the process of policy and institutional reforms has been complex and slow. This paper, based on several rounds of client consultation, attempts to synthesize emerging issues and challenges that confront food and agricultural sectors in Central Asia. It argues that developing institutions that will foster a policy dialogue on long-term issues related to food, agriculture and the environment within and among the Central Asian countries is fundamental to identify development strategies for the next 10 to 15 years. This will require setting priorities for future food, agriculture, and natural resource policy research and analysis that will help in generating and sharing information on the policy challenges and solutions useful for Central Asia in its quest to reduce malnutrition, eradicate poverty and protect the natural resource base.     

The food security challenge for southern Africa

This paper considers food security aims and instruments against a background of changed circumstances internationally and regionally. The international changes discussed are: a sharper focus on achieving macro-economic stabilization, which inter alia has led to closer scrutiny of what the public sector should be financing, and a decline in funding for agriculture; a reduced role for governments in commercial-type activities; the shift towards greater integration of world markets; and changing prospects for international aid flows. Regionally, southern Africa is moving away from a past of conflict and inward-looking economies, towards greater cooperation and trade, and less interventionist economic management.The commendable SADC food security strategy paper of June 1997 is considered, and its implications drawn out. The main messages are that (a) household food insecurity results from poverty, (b) national food insecurity results from faltering development and weak external trade performance, and (c) future strategies must therefore lie with greater efficiency in the use of resources and with patterns of development which are most effective in creating employment and incomes. Arguably there is therefore no case for a food security agenda that is separate from broad-based development aimed at poverty alleviation. This understanding of food security is at variance with some of the policies and development programmes in the region. Promotion of self-sufficiency in grains, specific food-security instruments, and controls over and interventions in markets may all be counter to improving food security for the region if they hinder policy and institutional reforms called for by the wider development agenda.The main roles for governments in promoting food security are discussed in terms of creating an enabling environment for development, correcting for market failures, and targeted measures to achieve social objectives. Food security needs both an urban and a rural focus, and involves all economic sectors. For rural areas, governments' roles may usefully be defined in terms of supporting household strategies aimed at raising and stabilizing incomes through livelihood diversification, intensification of farming, and migration.Two priority policy areas which are central to achieving food security objectives are discussed at some length: trade policy and the promotion of smallholder farming. The roles of government in these areas are discussed in the light of economic theory and past experiences in the region. A vision for a future trade regime is outlined, and strategic interventions by governments are identified. The challenge for governments in supporting smallholder farming is, first, to define with greater rigour than in the past the priority uses for public funds, and, second, to find much more efficient ways of delivering services than in the past. It will otherwise be difficult to make a case for reversing the decline in public funding for the sector.The paper ends with brief discussions of the roles for aid and for SADC in promoting food security, and with a question of whether a new initiative is needed to strengthen trade policy skills in the region.     

U.S. national security export controls: Implications for global competitiveness of U.S. high-tech firms

U.S. exporters of high-technology, ‘dual-use’ products are competitively disadvantaged in global markets by the complexity, range, and stringency of U.S. national security export controls. This paper demonstrates that fungibility of high technology and lax interpretation of multilateral export control agreements by other advanced countries have made the existing control regime ineffective. It further shows that persistent U.S. restrictiveness of exports in non-critical, widely available goods and technologies may needlessly and permanently erode U.S. firms' competitive position in existing as well as rapidly-opening markets worldwide. The need to revise the notion of national security to include not only military security, but also its complement, economic security, is discussed. The pivotal issue of enforceability of multilateral controls is explored, and corporate strategies for U.S. high-tech firms to achieve export control policy change are suggested.     

The development of food security policy for South Africa (SAFSP): a consultative process

Recognising the need for rapid delivery, and that the existing White Paper on Agriculture provided broad guidelines only, the Minister of Agriculture initiated a policy development process to provide a clear framework to guide Departments in their work. In October 1996, food security was identified as one of the priority areas requiring urgent attention. Given the particular nature of the South African economy, it was understood from the outset that food security was a multi-disciplinary issue, which required a policy framework beyond the confines of agriculture. The first step of the Food Security Policy for South Africa (SAFSP) is the result of the efforts of the Food Security Working Group responsible for the preparation of the Discussion Document on Food Security Policy. The process of developing the document was participatory and consultative. This paper describes the process involved in developing the food security policy, and further outlines some strategic measures to achieve food security. The paper consists of seven sections; Section 1 is the introduction and background and, Section 2 presents the history and concept for developing SAFSP. Section 3 discusses the process that resulted in a SAFSP discussion paper, while Section 4 and Section 5 provide an outline of the contents of the discussion document and policy proposals, respectively. Section 6 presents conclusions.
