A certain city has reached a mild drought level. What impact will this have on local life and food planting?

Although floods come quickly, the scope of their impact is relatively small, and their impact on agriculture generally lasts a short time. The impact is like a line. Crops can be replanted after the water recedes, but the drought affects a large area and has a greater impact on people's production and lives. Agriculture, industry, water transportation, logistics, and hydropower generation will all be severely affected.

1. I remember many times that my family’s turn was in the middle of the night, and then the family had to squat on the ground all night to wait.

So a severe drought of this level in Henan will not affect normal production and life. We have already done our work many years ago

If Henan is now If we still rely on the sky for food and farming, then there is a high probability that many of you sitting here will starve to death long ago. Keep your heart in your stomach. I have experienced severe droughts in my childhood. With the manpower and material resources we had at that time, we could overcome it. Why are we so timid now? We don’t even have this courage. Last year’s heavy rain There was also a period of hot and dry weather before. I can’t remember the exact number of days and the temperature.

I remember being in the steamer on my way to and from get off work a few days ago and feeling like I didn’t want to eat anything but ice cubes. When I saw the rainstorm warning and it started to rain, I felt quite happy. I thought it would be fine if it rained again. It was so hot that I didn't expect the rain to be too heavy. Later, the whole country knew the result. The temperature has been around 40 degrees Celsius for a while recently, which happened to be my eldest aunt's period and I was depressed because I couldn't even eat an ice cream.

2. Under this situation, Henan may not be the province most severely affected by drought.

The purpose of not allowing young crops to be harvested is to ensure that production will not be reduced next year and to maintain basic output. In early August, temperatures continued to rise in provinces and cities along the Yangtze River Basin, and rainfall continued to decrease, with some even falling at all. The meteorological station's precipitation monitoring map for the past 10 days shows that most areas south of the Yellow River will continue to be under the strong control of the subtropical high pressure and will still have a wide range of clear skies. In clear sky areas, large-scale heat waves will continue to occur, centered on the Yangtze River Basin.

In this case, the drought in the Yangtze River Basin will continue to worsen. Monitoring data from the National Climate Center of the China Meteorological Administration shows that meteorological drought has generally occurred in the Yangtze River Basin in my country, with many provinces reaching the level of moderate drought to severe drought. Special droughts have even begun to occur intensively in Sichuan, Chongqing, Hubei, Jiangxi, Zhejiang and other places. district. What's more serious is that the medium-term weather forecast points out that in the next 10 days from September 18 to 23, the Yangtze River Basin in southern my country will continue to maintain a large-scale area of ??little rain or no rain in Sichuan, Chongqing, Guizhou, Hubei, Hunan, Jiangxi, Anhui, Zhejiang and other provinces and cities for 10 days. Rainfall will remain the same as in the first half of the year, generally less than 10 mm, and drought may further expand and intensify.

3. There are even forecasts from the meteorological center’s supercomputer that until the end of August, the accumulated rainfall in the south of the Yangtze River will still be very scarce. In this case, the water levels of rivers and lakes will still be low. It will continue to decline, and the extreme drought area is likely to continue to expand. For many places in the Yangtze River Basin, the drought situation is becoming more and more serious. There are almost nine droughts in ten years, so why don’t you first ask why Henan builds so many water conservancy facilities? As long as I can remember, there has been a big battle in the countryside in the summer, which is to water the fields. Each household will have a turn for a certain time, and then the water from the big canal will flow into your property, and you need to be responsible for channeling it next to it. , allowing the water to flow where you want it to go without flooding it. As the saying goes, if there is a flood, a drought will cause a large area! The Yangtze River Basin is suffering from drought and high temperature disasters that are rare in history, which will have a great impact on the economy and people's livelihood.

Continued drought in the middle and lower reaches of the Yangtze River will directly lead to serious damage to crop yield and quality.

In areas with poor irrigation conditions, the booting, heading and grain filling of late rice will be adversely affected, causing wilting, ear jam, and reduced seed setting rate

; while the yield of cotton will and fiber quality will also be significantly reduced; at the same time, it will have a certain impact on autumn planting work such as vegetable sowing and transplanted rape seedlings

. In addition, continued high temperature and lack of rain will also affect the quality of citrus, grapefruit, navel, orange and other fruits. In terms of yield and quality, the fruits under sustained high temperatures and little rain are obviously smaller.

Continued high temperature weather has many impacts on the people.

Four. For example, it will directly lead to an increase in electricity bills. State Grid Nanjing Power Supply Company Market

Wu Fangzhu, deputy director of the Measurement Office of the Marketing Department, said: Relevant data experiments show that setting the same indoor temperature , every degree the outdoor temperature rises,

the energy consumption of air conditioners will increase by 6% to 10%. For every 1 degree Celsius increase in the global average surface temperature, the annual electricity consumption of residents in the middle and lower reaches of the Yangtze River will increase by about 9%

Continued high temperature weather will also affect people's health. In addition to increasing cases of heat stroke, it induces some diseases. It will bring extra difficulties to people who work outdoors

. It is the closure of the Three Gorges Dam that has led to poor water vapor circulation and heat exchange between the ocean and land, and the south-to-north water diversion

that has caused climate anomalies in the Han River Basin, the largest tributary of the Yangtze River. Another reason that many people ignore is that the Yangtze River failed to retain floods during the flood season, and its freshwater storage capacity was greatly reduced as we expanded the land reclamation from lakes.

By the way, Zhihu said that the price of ice cream has increased. When I went to pick up the express delivery, I bought ten ice cream sticks because there was a 20% discount for more than 10 sticks. I have never bought ice cream before. The news emphasized Henan and Hebei. It may be that drought conditions have occurred in several provinces on both sides of the Yellow River. In other words, the flow of water in the Yellow River is insufficient, and the water from the South-to-North Water Diversion Project has not been replenished this year. Generally speaking, it is probably related to the floods in Hunan. There is insufficient water discharge, so drinking water, that is, tap water, is the main source. ?The number of lakes in Hubei, the province of a thousand lakes, has been reduced by at least half, and the area of ??Dongting Lake and Poyang Lake is also shrinking sharply.

At present, the total freshwater storage capacity of all freshwater lakes in our country is only 220 billion cubic meters, which is only 42% of the 380 billion of Kusugul Lake in arid Outer Mongolia.

, not to mention a fraction of the 23 trillion of Lake Baikal in Russia.

How to reduce carbon emissions and increase green space while restoring the original water area is a difficult problem before us.

If the problem is solved well, the extreme high temperature and drought weather in the Yangtze River Basin in August this year can be avoided. If the problem is not solved well, this extreme high temperature and drought weather may spread and worsen! Everyone should protect the environment.
