Summarize the main idea and the main point (s) of the passage in no more than 60 words. Use your own -words as far as possible.China accounts for almost 22 percent of the world’s population and is one of the world’s largest and most rapidly growing economies. However, it has only 10 percent of the world’s total cultivated area and is having increasing difficulties in securing water for agricultural purposes.Despite population growing at an average rate of around one percent a year and its economy at around 9 percent a year since the early 1990s，China has so far maintained approximate self- sufficiency in agricultural products overall, in the sense that exports have been approximately matching imports. In fact, China has been the world’s fourth largest importer after the European Union, the United States and Japan.The ability of China's agriculture to keep pace with growing demand reflects a few key factors. Yield improvements have been achieved through more intensive use of inputs such as fertilizers, agricultural machinery and irrigation, and the introduction of advanced technologies in agricultural production.The Chinese government has had a policy of agricultural self-sufficiency. However, China's membership of the World Trade Organization (WTO) since 2001 could signal a greater preparedness to accept imports and embrace opportunities provided by export markets. Importantly, however, more than three decades of reforms have permitted the market to have a greater influence on what farmers are producing and selling. Reflecting these factors，China has been gradually shifting its agricultural production away from land intensive products，such as cereals, toward higher value, labor intensive products such as meat, fruit, vegetables, eggs, milk, fish and seafood. That is, China is producing more in line with its comparative advantage.____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
