Maybe many friends don’t know that there was a worldwide food crisis in the 1990s.

In 1991, world cereal production fell by 3120% compared with the previous year, and China's cereal production decreased by 1147%; in 1993, world cereal output fell by 3157% compared with the previous year, and China's cereal output fell by 2181%; in 1995, world cereal output fell again by 3100%. , And broke out a world food crisis affecting the world.

　　 "Will China Starve the World?" "And "Who can feed China?" "Two American papers caused an uproar in China.

　　 The most critical impact of this incident on the Song family is that China began to restrict the production of liquor and greatly increased the consumption tax on liquor.

　　 At the same time, the grain purchase quota of Chinese farmers is getting higher and higher, and farmers need to hand in more and more public grain. In addition, after 1995, China's grain harvest lasted for three years, and finally passed this food crisis smoothly.

　　 China’s grain output in 1998 reached its peak in the 1990s. For this reason, there are many experts studying agriculture, rural areas and farmers, but few pay attention to food security issues, because China's grain production is constantly increasing every year and grain prices continue to fall.

　　 Song Weiyang’s paper was first published in the "Fudan Journal (Social Science Edition, which attracted small-scale attention in the school. Then he submitted his manuscript to "Chinese Social Sciences", which was too high in style and failed to pass.

　　 It was given by Shenghai’s local "Academic Monthly", which caused discussions among many sociologists and experts on agriculture, rural areas and farmers.

　　 A small number of scholars agree with Song Weiyang's views, but most of them criticize Song Weiyang, thinking that Song Weiyang is alarmist. Their thinking is still a few years ago. They think that although the number of migrant workers is increasing, it will not cause large areas of farmland to be abandoned, because the land of these migrant workers will be cultivated by other people in the village, and the farmers can't wait for every inch of land. Plant food.

　　 But the reality is eye-catching!

　　 Just like Song Weiyang said in the paper, the area of ​​farmland abandoned in rural areas has not increased little by little, but has increased geometrically.

　　 This problem will be detonated next year, especially in southern rural areas, where the number of migrant workers and farmers has skyrocketed, and the area of ​​land abandoned has also skyrocketed. The national grain output has fallen year by year since 1999, and reached the bottom in 2003. With the abolition of the agricultural tax and the reform of the grain purchase and sale system by the central government, the burden on farmers has been reduced, and grain production has begun to slowly rise. It was also from this time that the country gradually released restrictions on the production of liquor, and China's liquor industry quickly prospered.

　　 Song Weiyang selected a few typical villages in the paper, listed the changes in the number of workers and the land abandoned over the past three years, and integrated a correlation coefficient.

　　 Calculated by this coefficient, the percentage of cultivated land abandoned in certain provinces of the Yangtze River Basin will reach 8% by 2003. This is horrible and terrifying, so it has been criticized as nonsense by many scholars.

　　 Facts will prove that Song Weiyang is correct. Even if the central government abolished the agricultural tax, the abandoned area in some provinces once reached 4%. If the agricultural tax is not abolished, it is absolutely possible that the abandoned area will increase to 8%, or even more!

　　 Inspired by Song Weiyang’s paper, several experts on agriculture, rural areas and farmers began to conduct field investigations in rural areas, and published several papers at the end of the year. One of them even appeared in "Chinese Social Science". The conclusions they reached were almost the same as Song Weiyang, which quickly aroused large-scale discussions in academia.

　　 As for the calculation coefficient of the number of rural workers and the area of ​​land abandoned by Song Weiyang, it will be used in various ways in the next seven or eight years, specifically for the study of the problem of abandonment of cultivated land. It was once called the "Song Weiyang coefficient" by academic circles. Of course, this coefficient has only existed for seven or eight years, because after 2005, the phenomenon of rural demolition has become more and more common, and it is not accurate to use this coefficient to calculate the abandoned area.

　　 Many years later, someone turned up Song Weiyang's paper from Zhiwang.com, and then popularized the "Song Weiyang coefficient". Netizens said: "Papa Song is a sociologist who was delayed by business."

　　 But now it is regrettable that the top domestic academic journals do not accept Song Weiyang's papers at all, and the relevant departments and most scholars do not pay attention to it. Only a few experts on agriculture, rural areas and farmers were shocked by Song Weiyang's data and went to the countryside to conduct field investigations at his own expense.

　　 It’s normal to think about it. There have been three consecutive years of bumper agricultural harvests. Who cares about the food crisis?

　　 Groundless worries!

　　Even this thing is not politically correct. At this time, the mainstream public opinion is shouting: The Chinese can support themselves! -From the government to the private sector, they are praising the increase in grain production year after year, and are thinking hard about countermeasures for the fact that there is too much grain and low grain prices hurt farmers.

　　 Well, the mainstream research direction in academia is: If grain production continues to increase next year, how to stabilize grain prices and how to protect the interests of farmers.

　　...

　　The graduation ceremony is just around the corner, and there is heavy rain everywhere in the world.

　　Shenghai has been on and off for several days. Song Weiyang's nest is almost moldy in the coffee shop. Xifeng's sales branches in various places are even more troublesome-it is the peak season, but the sales of beverages have plummeted!

　　 There were no customers in the shop. Lin Zhuoyun reached out to catch the rain under the eaves: "When can this rain stop? It's been a whole day in a row."

　　 Song Weiyang lay on the table and said: "There may be a major flood this year."

　　 Lin Zhuoyun said: "There are floods every year."

　　 "This year may be different." Song Weiyang said.

　　 Lin Zhuoyun smiled and said, "Do you want to switch to fortune telling?"

　　 No matter how bad Song Weiyang's memory is, he still remembers the 98 floods, the huge floods of 318 million mu across the country!

　　 From the perspective of time, the outbreak of the flood coincided with the critical time of rice heading and harvesting, which caused a large area of ​​farmland in the flood-affected area to reduce production. But even so, the national grain harvest in 1998 was a bumper crop, reaching the peak value of agriculture in the 1990s. This corroborates Song Weiyang's thesis that the reduction in agricultural production since 1999 has nothing to do with other things, but more and more part-time jobs and less and less farming, which is purely a result of abandonment.

　　 Lin Zhuoyun glanced at the clock on the wall: "Doudou will soon be over from school. The rain is so heavy, you can drive to pick her up."

　　 "Then I'm leaving." Song Wei raised his body and said.

　　From Time Cafe to Fudan Attached Elementary School, the straight-line distance is less than one kilometer, and Doudou usually walks to and from school.

　　 Song Weiyang drove that shit-yellow dilapidated van, came to the school gate in minutes, and then squatted in the car to play the mobile game-Snake!

　　 Yes, Song Weiyang, who is the owner of PHS, has got a new mobile phone, Nokia 6110, the world's first mobile phone that can play games.

"Jingle Bell!"

　　 When the greedy snake was about to fill the screen, the school bell finally rang.

　　 Not long after, Doudou ran over with an umbrella, UU reading www. uukanshu.com got into the car with a smile and said, "Uncle, our car is the most conspicuous, you can recognize it from a long distance."

　　 "Of course, it's much easier to use than Mercedes-Benz BMW. Fasten your seat belt." Song Weiyang said.

　　 Doudou will enter junior high school next semester. She is already a big girl, and she keeps chatting with Song Weiyang about school fun.

　　 Back to the coffee shop, Doudou rushed to the arcade machine, turned on the coin, and went in one go.

　　 "Go do your homework!" Lin Zhuoyun appeared like a demon.

　　 Doudou bargaining: "Take a coin, and I will do my homework after I hit it."

　　 "Immediately, right away!" Lin Zhuoyun said.

　　 "Write as you write." Doudou pouted and left.

　　 Lin Zhuoyun began to complain about Song Weiyang: "You shouldn't buy the arcade machine."

　　 Song Weiyang smiled and said, "Children, work and rest together."

　　 Lin Zhuoyun said: "My sister opened a shop in the city, and she can't come back a few times a month. Of course, I want to urge Doudou to study hard. It's okay for you to add chaos!"

　　 "Hehehe." Song Weiyang smiled smirkly.

　　 Suddenly, the phone rang to help, but it was from the detective office: "Boss, I found it. Song Xinghua has retired, and Song Weihong and Li Chenggong are both laid-off workers."...
