Chapter 1147 Overthrowing the Consensus of the Whole World!

For Chang Haonan, this number is indeed conservative.

According to a comparison of remote sensing and statistical results from Mongolia Province, the area of ​​sandy and semi-sandy land that has the potential to be transformed in Wumeng City in the east alone should be around 60-80 million acres -

Because the huge amount of degraded land area is not a long-standing thing in statistical lists, local governments have no incentive to make false reports on this kind of data.

The results are basically credible.

Moreover, although Chang Haonan had never been exposed to any agricultural projects in his previous life, he also knew that Mongolia Province had actually been developed into a top agricultural production area.

Thanks to the relatively flat terrain, it is still the kind of production area that does not require intensive farming.

The reason why I fold it in half as soon as I open my mouth is mainly because of the psychological endurance of the leaders.

Otherwise, when you came up and said you wanted to build nearly 100 million acres of new farmland, it was a bit exaggerated.

But...

It can only be said that Chang Haonan's considerations are indeed a bit humane.

But not much.

What is the concept of 40 million acres?

According to statistics in 1996, the total cultivated land area in China was only a little over 1.9 billion acres.

In 2003, the meeting did not propose a red line for cultivated land. Considering the large amount of occupation over the years, the actual optimistic estimate is only about 1.8 billion acres.

This is equivalent to conjuring up 2.2% of the existing cultivated land area out of thin air.

If you put it in the general field, increasing production capacity by only 2% is really not worth mentioning.

But this is agriculture.

A lifeline industry in the physical sense.

If necessary agricultural products are short of 2%, then the market price will definitely not only increase by 2% without considering policy deployment.

Instead, it will rise until 2% of people starve to death.

Therefore, after hearing this number, he still heard a few faint inhaling sounds coming from around him.

Li Zhongyi, who had been sitting on the edge just now and muttered about making a fortune, suddenly raised his head and made a tactical tilt at the same time.

Looking at Chang Haonan, one sentence could clearly be read:

"Little ancestor, what kind of cruel work are you going to do?"

Seeing that the atmosphere was a bit cold, Chang Haonan finally realized that perhaps transforming 40 million acres of cultivated land was still a bit beyond imagination for China at the moment.

But he was also very wronged.

It was obviously the leader who insisted on asking "without considering the capital investment and other costs" just now.

Then you should expect to get a very exaggerated number...

In fact, Chang Haonan himself had some preconceptions about this.

At the beginning of the 21st century, both internationally and domestically, there was overwhelming publicity that global warming would lead to land degradation and reduced agricultural production, etc., which led to everyone generally having pessimistic expectations about the future.

Leaders are also human beings and will be affected by this kind of public opinion.

But in fact, after more than ten years, everyone discovered that this matter also depends on the situation.

For Western Europe and the United States, the above conclusion is indeed correct.

But for Central Asia, East Asia and North Asia, the northward shift of precipitation and isotherms is beneficial to agricultural production.

Therefore, there is indeed a huge difference in concepts between Chang Haonan, who has experienced these things, and people who were "born" in this era.

Fortunately, he also left a hook before, so he can continue to make up for it now:

"Of course, this is without considering other external constraints... If such a large-area soil improvement project can be implemented, in addition to the visible economic and social benefits, it will even have an impact on the ecology of the entire Northeast Asia region. The impact on the environment is no less than that of a century-old project like the South-to-North Water Diversion Project, which mobilizes the entire country.”

"Therefore, even if it is only the first phase of the project, it needs to be further implemented in stages. Considering that this is still a new technology, especially the effect under long wheelbase and large area conditions is lacking data, so first of all, we are preparing to use 3- In five years, we will conduct a medium-scale experiment covering an area of ​​500,000 to 1 million acres, and then..."

However, before Chang Haonan could finish explaining the entire three-step plan, another leader raised his hand and interrupted him:

"We will talk about these processes in detail later... If you really think that eastern Mongolia alone has the potential to transform tens of millions of acres of land, then no matter how small the scale of the first step is, when planning It must be carried out in accordance with the standards of the century project.”

"So, there are a few issues that you need to consider carefully."

Although he was indeed shocked by Chang Haonan's answer at first, he was a senior leader who was used to the world and quickly regained his rationality.

"Even the eastern part, which you just mentioned, has relatively good climate conditions, is still a semi-arid area. The surface water systems that Mongolia's agriculture can rely on are mainly the Hetao Basin of the Yellow River and the Xiliao River, but these two water systems are also It is impossible for all the industrial and mining industries in the four cities of Hohhot, Baotou, Echi and Chi to be used for agricultural production.”

Although there was no map in the entire conference room, he still stretched out his hand as he spoke and pointed at several locations in the air in front of him.

Almost exactly corresponds to the places just mentioned.

Apparently very knowledgeable about the actual situation:

"If agricultural production relies on groundwater for a long time, it will undoubtedly lead to overexploitation, which is not a long-term solution."

"In this case, if the decision-makers really pass the mid- to long-term plan for 40 million acres, or even a larger scale, how are you going to solve the water conflict?"

This question is a very accurate one.

It is also the part of the plan that has the biggest loopholes on the surface.

Although the five eastern leagues and cities are part of the Northeast in terms of division, geographically, only part of the land east of the Greater Khingan Range is actually an extension of the Songnen Plain.

As a matter of course, it has long been a major agricultural production area.

The three sandy lands mentioned by Chang Haonan before cannot really benefit from the environmental dividends of the Northeast.

And at the beginning of the 21st century, it was the most serious stage of soil erosion.

The water resource balance of Inner Mongolia Province and even the entire North is already at a precarious level.

The Yellow River even had an outrageous record of zero runoff into the sea for several consecutive years.

In this case, let alone 40 million mu, even 4 million mu may become the last straw that breaks the camel's back.

Sitting next to him, Zhuang Bingchang, who had not spoken since he introduced his work, changed his face slightly.

He has worked in the Northeast and Northwest for a long time and knows very well that all the situations the other party said are true.

In fact, Chang Haonan had not revealed this figure of 40 million mu to him before...

However, the former showed a slightly happy expression-

Asking such a specific question shows that the other party has been moved.

If others keep discussing some topics floating in the sky, it will be really troublesome.

Therefore, he immediately replied:

"From the perspective of treating the symptoms, a number of water conservancy facilities can be built in this area."

"As you said just now, the Xiliao River can support the irrigation of the Horqin Sandy Land and the eastern part of the Hunshandake Sandy Land, but it suffers from insufficient flow. Therefore, we can consider learning from the successful experience of the South-to-North Water Diversion Project, diverting water from the Chuoer River to the Xiliao River, supplying water to cities and industrial parks along the route, combining irrigation with power generation and other comprehensive utilization."

When Chang Haonan said this, he only heard a burst of laughter from the surroundings.

"Nothing."

Soon someone explained:

"Thank you Academician Chang for your good wishes for the South-to-North Water Diversion Project..."

Jokes aside.

Although the first phase of the South-to-North Water Diversion Project has just started, there are still 300-400 kilometers of water conservancy projects even in the investigation stage before the project was established.

Compared with the earth-shaking big pie mentioned above, this "Yinchujiliao" proposal seems less out of line.

"You just said that this is a symptomatic treatment..."

The leader who asked the question first took the lead in calming down the somewhat loose atmosphere:

"So it sounds like... Academician Chang, do you have a way to cure the root cause?"

This time, Chang Haonan shook his head very straightforwardly:

"With today's human technology level, it is still a bit too difficult to completely overcome the laws of nature..."

Some eyes then revealed a bit of regret.

If the climate can be fundamentally improved, it will definitely be a sure win in long-term international competition.

However, Chang Haonan's words have not yet been finished:

"So, it is not me who can cure the root cause, but the environment itself."

In just one sentence, many people experienced a great ups and downs in their mentality.

"The environment itself?"

A leader from the land and resources system suddenly became interested:

"Academician Chang, you don't support the plan to dig a hole in the Yanshan Mountains to let the warm and humid air from the Bohai Sea blow into Inner Mongolia, do you?"

Chang Haonan: "..."

Zhuang Bingchang: "..."

Other leaders: "..."

Chang Haonan himself didn't even know that someone had proposed such an idea.

It sounds similar to digging the Himalayas to let the Indian Ocean air flow blow into Xinjiang Province...

He shook his head quickly:

"There is no need to be so troublesome..."

"In fact, as long as the current trend continues, then in a dozen years, with global warming, the water and heat conditions and environmental carrying capacity in central and western my country will naturally improve..."

"!!!"

Dozens of people in the conference room almost all focused their attention on Chang Haonan again-

The 40 million mu of arable land just now is only exaggerated in terms of quantity.

After all, China has never stopped researching soil consolidation and sand control technology since the founding of the country.

It's just that I never thought it would have such a good effect in the past.

However, as mentioned before.

This conclusion was made in 2004, but the direction is completely different from the currently commonly defined "common sense"!

"Can you tell me the reason?"

Someone soon asked:

"Is it calculation, or..."

"The evolution of the earth's climate is too complicated, and there is almost no 100% reliable theory... Calculation alone is definitely not enough."

Chang Haonan replied:

"My judgment is based on two reasons. One is the analysis of the laws of soil stratigraphy and historical climatology. The increase in earth temperature is not a bad thing for a continental country like my country..."

"Second, my country has systematically implemented a surface greening project that has lasted for more than 40 years and is the largest in human history. Although manpower alone is not enough to reverse nature, it has the foundation to undertake the improvement of climate conditions. This is an advantage that no other country has, and it also means that we cannot copy the research results of foreign researchers in the field of ecological environment..."

"Academician Chang, wait a minute..."

The leader who had just asked the question took a deep breath and did not let Chang Haonan continue.

It must be admitted that what the latter said just now was indeed very nice.

Especially the second point, which almost aimed at the preferences of his generation.

But reason told him that the more nice words were, the more attention should be paid to judging their accuracy.

Moreover, Chang Haonan was not a geophysical expert.

Compared with the rich experimental data and calculation process he had brought out when introducing the soil consolidation and sand control technology, the explanation of these few sentences was a bit too thin.

As a scholar, Chang Haonan can make speculations that are in line with logic and existing theories based on his own judgment.

But as a decision maker, he must ensure that he listens to both sides.

At least he must find professionals to prove it.

"This is a serious matter. We may have to confirm the correctness of this conclusion again."

"So I propose to adjourn temporarily and continue to discuss this issue when the time is right..."
