Africa has 100 times more groundwater reserves than the surface

Africa in many people's impression is the high temperature, drought, and water shortage, often can see some news information, many Africans head to the water basin to go far away to find water. Is Africa that short of water? This is not the case, Africa's groundwater resources are very rich, about 100 times more than surface water, why do not Africans drill wells for water?

According to research findings, Africa's groundwater reserves are extremely rich, in Africa's largest desert, the Sahara Desert, groundwater reserves up to 375,000 cubic kilometers, and are freshwater resources. Great Lakes in North America, is the world's largest group of freshwater lakes. And the Sahara Desert groundwater reserves are as much as 16 times the water reserves of the Great Lakes in North America.

The rest of Africa's groundwater reserves, compared to the Sahara Desert region is more abundant. According to preliminary statistics, Africa's theoretical water reserves are up to 1,155 million kilowatts, second only to Asia. Since the water reserves are so rich, why is Africa still so short of water?

That is because the groundwater resources in Africa are too deep from the ground, take the Sahara desert, the average depth of groundwater is about 230 meters, and it is very difficult to discover water resources in these areas. And in recent decades, in many areas in Africa because of the climate, precipitation is decreasing year by year, and the surface of freshwater resources is difficult to protect people's normal life.

Although you can drill wells for water, the difficulty of drilling wells for water is relatively high, some places may dig down a dozen meters on the water, but many places down dig dozens of meters or even hundreds of meters may not be able to dig the water layer up. Some places with money will buy large machinery and equipment to drill wells, which can alleviate the lack of fresh water, but most are not very rich areas, to popularize is more difficult, and the local economy can not support it.

Manual drilling alone, good luck digging a dozen meters to dig the water, but most of the time there is no water. Manually digging a well too deep is not practical, so Africans would rather walk dozens of kilometers to find water, rather than drill a well for water. Not unwilling to drill wells, but the payoff is not proportional to the return.

If you have running water at home, do you think water is an easy resource to obtain, but in Africa, every dry season to get water is how difficult, each time to get water disintegrates, and also to walk 10 kilometers round trip, today over time to tell the story of a ten-year-old child in Ghana, Africa, to take care of his sick mother to go to work in a brick factory, early in the morning Zenny with Buddy in the brick factory to work, to see them make the familiar technology, The child paved the soil on top of the mold, she moved to an open space and took out the mold, so that two bricks were made, each time the production to Sichuan to wash the mold, see the two children so ink work, do not think they are sisters, in fact, not, they are classmates, but three years ago in school when they met,...
