Explain the state of agriculture in …

Although China's agricultural output is the largest in the world, only 10% of its total land area can be cultivated. ... 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. These are the Northeastern Plain, the North China Plain and the Middle-Lower Yangtze Plain . Benefiting from climate, topography , economic and historical factors, eastern China has become the major agricultural production area in the country. It is a staggering accomplishment that China is able to feed 20 percent of the world's population with only 7 percent of the world's farmland. The relationship between the Chinese people and their land is further complicated by the uneven distribution of the population.
