Can the Chinese catch up with the United States in per capita grain output?
China and the United States are the two largest food producers in the world. The combined grain production of China and the United States is as high as 126.6 billion tons, accounting for 27% of the world's total grain production46% of 6.8 billion tons, nearly half of the world!This shows the position of our country and the United States in the world's grain industry!
At present, China's grain output is 695.4 billion tons, the United States of China 57.1 billion tons. Our country is the country with the largest grain production in the world!However, objectively speaking, China's food security is still far inferior to that of the United States. Why?Let's move on!At present, China's grain production is 1 more than that of the United StatesMore than 200 million tons. However, China's population is as high as 1.4 billion+, and the population of the United States is only 33.3 billion!Our population is more than four times that of the United States. This also determines that China's per capita grain output is inferior to that of the United States. China's per capita grain is only 492 kilograms, and the United States is as high as 1,715 kilograms. Although China's per capita grain has already exceeded the international per capita basic food ration line by 250 kilograms, the international food and clothing line by 28 kilograms, and the international security line by 400 kilograms. But the per capita gap with the United States is too great!The per capita food of the United States is 35 times!At most, China's current grain is to make a little contribution to the world's food security under the condition of having more independence!The United States, on the other hand, can use food as a weight to show its influence in the international community
So there is no room for further improvement in China's per capita grain?The answer is yes, of course, but space is quite limited!Our country is currently 695.4 billion tons of grain corresponds to 136 tons of arable land30,000 square kilometers;In China, the amount of arable land that can be fully cultivated is 14330,000 square kilometers, which shows that China's cultivated land reclamation rate has reached more than 95%. If China's cultivated land is completely reclaimed, according to the current population size, the per capita grain will be 510 kilograms at most
And what about the United States?United States 57.1 billion tons of grain corresponds to 152 tons of arable land30,000 square kilometers;However, the size of arable land in the United States is as high as 3.73 million square kilometers, and if all the suitable arable land in the United States is cultivated. Then the grain production of the United States will be as high as 1.6 billion tons, and according to the current size of the American population, then the per capita grain of the United States will be as high as 4,800 kilograms, while China's is 520 kilograms. The average American will be more than 9 times that of our country!
Of course, the size of our population is also gradually decreasing. If the population size of Japan and the United States are both about 600 million!According to the current Sino-US With the scale of arable land they have, China will have 1,160 kilograms of grain per capita, while the United States will have 952 kilograms!In this way, China's per capita grain will surpass that of the United States;However, China and the United States have maximized their respective farming potential, and if they are calculated according to a population of 600 million, China's per capita grain is 1,200 kilograms, and the United States is 2,670 kilograms!The United States is still more than twice the size of our country!
So on the whole, if the population of China and the United States does not change much. Under the condition of the existing cultivated land area and the limit cultivated land area, it is very difficult for China's per capita grain to surpass that of the United States!
