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

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

Two American papers, "Can China Hungry the World?" and "Who Can Support China?", caused an uproar in China.

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

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

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

Song Weiyang's paper was first published in the "Journal of Fudan (Social Science Edition)" and attracted a small-scale attention from the school. Then he submitted it to "Chinese Social Sciences". The journal has a very high style and has not been approved.

However, Shenghai's local Academic Monthly has given it, which has attracted discussions among many sociologists and experts on rural issues.

A small number of scholars agree with Song Weiyang's point of view, but most of them criticize, believing that Song Weiyang is an alarmist statement. Their thinking is still a few years ago, believing that although the number of migrant workers is increasing, it will not cause large-scale abandonment of arable land, because the land of these migrant workers will be cultivated by other people in the village, and farmers want to grow grain on every inch of land.

But reality can shock people!

As Song Weiyang said in his paper, the area of ​​abandoned farmland in rural areas does not increase little by little, but increases geometrically.

This problem will be ignited next year, especially in rural southern China, where the number of migrant workers soared, and the area of ​​land abandoned soared. The national grain output fell year by year since 1999 and fell to the bottom in 2003. With the central government abolishing agricultural tax and reforming the grain purchase and sales system, the burden on farmers has been reduced, and grain output began to slowly rebound. It was also from this time that the country gradually relaxed the restrictions on liquor production, and China's liquor industry flourished rapidly.

In his paper, Song Weiyang selected several typical villages, listed the changes in the number of workers and abandoned areas over the past three years, and formed a correlation coefficient.

Calculated through this coefficient, the ratio of arable land abandonment in some provinces in the Yangtze River Basin will reach 8% by 2003. This is too terrifying and terrifying, so it is criticized by many scholars as nonsense.

Facts will prove that Song Weiyang is correct. Even if the central government abolishes the agricultural tax, the abandoned area in some provinces will once reach 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 rural issues began to go to the countryside for field investigations, and published several papers at the end of the year, one of which even appeared in "Chinese Social Sciences". The conclusions they came to were almost consistent with Song Weiyang and quickly attracted widespread discussions in the academic community.

As for the calculation coefficients of the number of rural workers and land abandoned area created by Song Weiyang, it will be used in various ways in the next seven or eight years, specifically for studying the problem of farmland abandoned. It was once called the "Song Weiyang Coefficient" by the academic community. Of course, this coefficient only existed for seven or eight years, because after 2005, rural demolition phenomena became more and more common, and using this coefficient to calculate the abandoned area is inaccurate.

Many years later, someone dug out Song Weiyang's paper from CNKI and then popularized the "Song Weiyang coefficient". Netizens said: "Song's father is a sociologist who has been delayed by business."

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

It’s normal to think about it. There have been a bumper agricultural harvest for three consecutive years. Who is still concerned about the food crisis?

Worrying nothing!

Even this thing is not politically correct. At this time, mainstream public opinion is shouting: Chinese people can support themselves! - From the official to the people, they are cheering for the increase in grain production year by year, and they are thinking hard about countermeasures for too much food and low grain damage to farmers.

Well, the mainstream research direction in the academic community is: If grain production continues to increase next year, how should grain prices be stabilized and how should farmers protect the interests of them?

...

The graduation ceremony is approaching, and heavy rain falls across the country.

Shenghai has been on and off for several days, and Song Weiyang is almost moldy in the cafe, and Xifeng's sales branches in various places are even more troublesome - it is the peak season, but beverage sales plummeted!

The store was empty and there were no customers. Lin Zhuoyun reached out to the eaves to receive the rain: "When will this rain stop? It's been a whole day."

Song Weiyang slapped 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 change your career and fortune telling?"

No matter how bad Song Weiyang has a poor memory, he still remembers the 98 flood, a major flood with a disaster area of ​​318 million mu!

From a time perspective, the flood outbreak is at the critical moment for rice heading and harvesting, which leads to a large-scale reduction in farmland production in the flooded areas. But even so, the national grain harvest in 1998 was a bumper harvest and reached the peak agricultural value in the 1990s. This proves that Song Weiyang's paper, the agricultural production reduction since 1999, has nothing to do with anything else, that is, more and more people work and less land farming, which is purely caused by abandonment.

Lin Zhuoyun glanced at the clock on the wall: "Doudou is about to get out of school. It's raining so hard, you can drive to pick her up."

"Then I'll leave." Song Wei raised his head and said.

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

Song Weiyang drove the shabby yellow van and arrived at the school gate in minutes, and then squatted in the car and played mobile games leisurely - Snake-eating!

Yes, Song Weiyang, the boss of Little Lingtong, has changed his phone to a new one, Nokia 6110, the world's first mobile phone to play games.

"Dingling!"

When the greedy snake was about to eat the screen, the school ringtone finally rang.

Soon, Doudou ran over with an umbrella, got into the car with a smile and said, "Uncle, our car is the most conspicuous and you can recognize it from a distance."

"Of course, it's much better than a Mercedes-Benz and BMW. Fasten your seat belt." Song Weiyang said.

Doudou will be going to junior high school next semester. She is already a big girl and keeps talking to Song Weiyang about interesting things in the school.

Back at the cafe, Doudou went straight to the arcade machine and started the computer and put coins into the work together.

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

Doudou bargained: "Get a coin, and I will do my homework after I finish the game."

"Immediately, right now!" said Lin Zhuoyun.

"Write it." Doudou pouted and left.

Lin Zhuoyun began to blame Song Weiyang: "You shouldn't have bought the arcade machine back."

Song Weiyang smiled and said, "As a child, it's a combination of work and rest."

Lin Zhuoyun said: "My sister opens a store in the city and can't come back a few times a month. Of course, I would like to urge Doudou to study hard. You can make up for trouble!"

"Hehe." Song Weiyang smiled foolishly.
Chapter completed!
