Development of a global balance model on demand and supply in major cereals for assessing CO₂emissions and woody biofuel supply potentials by arable land cultivations

Abstract

This research targeted the potential evaluations of CO₂emissions and woody biofuel when the cultivated arable land isexpanded by increase of cropproduction. In orderto consider the issuesas well as the soaring crop prices and population growth in developing countries, food supply-demand balance model is constructed, and then the worldwide mid-term market analysis of major crops is accomplished. The analysis results show that demand of all main crops is increasing especially that of soybean. Moreover the largest impact of increasing demand is appearing in China and South America and result of such situations is that much more production and cultivated arable land in South America isrequired to fulfill the increasing demand. Finally asone of research results, South America would act asa dominating role in maintaining the supply-demand balance of cropsin the future.
