query: What is the average farm size in China?
passage: Agriculture in China
Although China's agricultural output is the largest in the world, only about 15% of its total land area can be cultivated. China's arable land, which represents 10% of the total arable land in the world, supports over 20% of the world's population. Of this approximately 1.4 million square kilometers of arable land, only about 1.2% (116,580 square kilometers) permanently supports crops and 525,800 square kilometers are irrigated. The land is divided into approximately 200 million households, with an average land allocation of just 0.65 hectares (1.6 acres).
passage: History of agriculture in the People's Republic of China
China is an important producer of oilseeds, including peanuts, rapeseed, sesame seed, sunflower seed, and safflower seed. Oilseed output in 1955 was 4.8 million tons. Output, however, did not expand between 1955 and 1975, which meant per capita oilseed availability decreased substantially because of population growth. Production from 1975 to 1985 more than tripled, to 15.5 million tons, but China continues to have one of the world's lowest levels of per capita consumption of oilseeds.
