Domestic Demand Composition and Projections for Major Upland Crops

摘要

Major upland crops, maize, soybean, cassava and rice, are consumed in various forms. In order to study the future market prospects of these crops, domestic demand was divided into major uses or demand components which were analyzed by country. Demandcomposition of the four commodities is summarized in Table 1. Moreover, middle-term demand projections were carried out. In estimating the future quantity demanded, a common simple econometric method using income and population growth rates and income elasticities was employed as far as possible. In cases where relevant income elasticities were not available, the most simple time trend approach of the amount produced was applied. The results of demand projections to the year 2000 are summarized in Table 2.
