Abstract:

Central Asia is of great significance for maintaining world food security because of its special geographical location and high grain production capacity. Exploring the potential of grain production in this region will help alleviate the global food crisis. In this paper, the GAEZ method, combined with the FAOSTAT database, is used to quantitatively analyze the potential yield per unit area and potential area of nine grain crops in the five Central Asian countries. And based on the assumption that the production area is a constant, the output per unit area is a constant, while the output per unit area and the production area are changed. In addition, the grain production potential, and the range of development potential in this region are measured. The results show that among the five countries, Kazakhstan has the greatest potential for grain production and development potential. In terms of crop types, wheat has the greatest potential for grain production and development potential, followed by barley; while oats, rye, sorghum, millet and buckwheat have the least grain production and development potential, and are concentrated in Kazakhstan In addition, sorghum has the largest range of development potential in the whole region.

Key words: production potential, development potential, grain, Central Asia
