摘要

20 years already has passed after going into the 21st century. The world's population is steadily increasing and has already reached about 7.5 billion. It is estimated to exceed 9.5 billion by 2050. China, with the largest population is expected to continue the population growth in the future by stopping the one-child policy. The world population is expected to surpass 10 billion within the 21st century. Resources are limited on the confined earth. We must survive using our limited resources well, especially the farmland. The farmland per capita continues to decrease. Therefore, it is necessary to raise the land productivity of agriculture. In order to increase land productivity, it requires timely and exact operations. Agricultural land productivity cannot be increased without the proper agricultural mechanization and should be promoted through the development of new means of mechanization in all regions. At the same time, the problem of declining agricultural labor force is emerg-ing all over the globe.
