註釋"Food security, assuring to all human beings the physical and economic access to the basic foods they need, is a broad, cross-cutting issue which has implications for a number of different sectors in the economy. Food security is often associated with food self-sufficiency and the need to grow more food. However, in reality it has much stronger links with issues of poverty, employment and income generation. For low income economies, where a large percentage of the population live in rural areas and depend on agriculture for their income, increasing food production may be an important element in increasing food security, but only because it increases small farmer income. In this manual, we set out a framework for assessing food security in an economy, and develop a model for evaluating the impact of economic policy measures, and in particular the package of policy measures often referred to as adjustment policy, on food security in a country."--Introduction.
