Wie Saudi-Arabien Seine Wüste In Einen Grünen Wald Verwandelt

this is

Saudi

Arabia, which with an area of ​​2 million square kilometers is the 14th largest country in the world by land mass, however 95% of the kingdom is a hot dry desert where you can find a lot of sand, it is also one of the few. countries where there is not a single river, it is a country where the average annual rainfall is less than 150 mm; however, if you take a closer look, you will see something totally unexpected. Farmland

Saudi

Arabia is crisscrossed by a network of farmland where farmers are prosperous and can harvest many different fruits an unusual feature in the hot desert which will also be immediately noticeable as most of the arable land is in the county the country has 35000 square kilometers of arable land that is larger than the Netherlands and more than three times the size of katata in However, in the early 1960s,

Saudi

Arabia only had 400 square kilometers of arable land. farming as ko If the oil-rich kingdom was able to multiply its acreage in such a short time, in this video you will learn the ingenious methods

Saudi

Arabia used to turn its desert into an oasis of farmland

Saudi

Arabia may be home to many sand dunes, but that was not always the case around 10,000 years ago in Arabia, significantly more rainfall and an expansion of lakes and vegetation than it made possible human settlements throughout the peninsula, however, in the following millennia, a series of extreme droughts led to drastic changes in the ecosystem.

There is evidence that people adapted and continued to inhabit the sandy land from the fact that the Juba oasis was inhabited by humans during the dark millennium of a dry spell some 5,900 to 5,300 years ago in which much of it is said to have of Arabia was destroyed. uninhabitable, in other areas of northern Arabia, people built walls around oases and built landscape features to catch draining water and start digging wells while water is scarce on the surface,

Saudi

Arabia sits on water reservoirs , the so-called aquifers, which are similar to the kingdom's huge oil reserves, but

Saudi

Arabia has been pumping water from the ground for years; most of the water is withdrawn for agriculture However, where large-scale irrigation has enabled cultivation and harvesting, there is the problem of pumping groundwater which can actively dry up, especially when used for large-scale irrigation such as this is the case of

arabia to conserve its water

saudi

arabia introduced a technology that has made a big difference this technology is pivot irrigation what is pivot irrigation and where did it come from in 1948 an innovative farmer from Nebraska named Frank Seilbach developed a novel irrigation system that he patented in 1952 Center Pivot irrigation is done mechanically employs an irrigation system that irrigates crops in a circular pattern around a center pivot which explains why the acreage shown at the beginning of the video it is circular most of it is a long radial tube supported by irrigation towers these towers revolve around a central point of the whole mechanism The pipe ra dial itself consists of evenly working nozzles that distribute water to surrounding plants.

As the pipe gradually rotates, the water is evenly discharged from the nozzles to provide nutrients to the plants. With the irrigation pivot radial pipe system, water flows in a straight line across the field, all pipe nozzles have the same flow rate and cover the same area ensuring that water is distributed evenly over the crops. Center pivot can cover up to 130 acres depending on the length of pipes connected to them and nearly 155 acres on a swing arm system, making the system suitable for large-scale agriculture. the irrigation system includes the pivot to stretch the entire mechanism rotates is the area where the water first enters the pivot tubes this is also where another important component is the control panel the control panel contains the hardware that allows farmers to operating the machine is the brain of the system from which the farmer can start and stop the machine, change direction and change operating modes, eg dry or wet operation. and advanced digital control panels to the next Components include the power tower or propulsion unit, the part of the machine that touches the ground, and associated hardware that allows the system to move.

It usually consists of wheels, a base that supports a power train and other major structural supports, there is also the tower. The box, which is the propulsion unit, controls and ensures that the entire system moves in the right direction and for the required time. With pivot irrigation, farmers can easily apply water evenly over large areas. Also, the amount of labor during harvest time is significantly reduced, solving two problems. high labor costs and the inconsistency of farm workers, this method of irrigation also helps save huge amounts of energy in the long run, it is also known to be much more efficient when it comes to water use, it helps prevent runoff and maintains the water bill farmers can be considerably reduced also with this system farmers can better control the water level in their soil the semi-automatic mechanism and the lateral movement of the sprinklers make it easier for farmers to manage the water level is has shown that the efficiency of water application with central irrigation contributes is almost 80%, which is much higher than traditional methods.

A centralized irrigation system is very versatile because it can irrigate almost any type of crop, and the same system can also be used to apply fertilizer, pesticides, and other necessary fluids—about two-thirds of all irr igated areas of

Saudi

Arabia are irrigated with the Center Pivot irrigation system, which has helped convert many acres of land into intensively irrigated farmland. Government support and incentives for farmers to grow food. Initially, farmers in

Saudi

Arabia complained of excessive corrosion on the laterals of center pivot irrigation systems because they used different water quality standards. To combat the problem, many farms are replacing expensive steel laterals with polyethylene pipe to combat the non-corroding problem.

Polyethylene side channels equipped with short downpipes were placed directly under the standard steel pipe and 150 to 200 cm above the soil surface. Farmers started this transformation with input from their own experience and from their technicians without the distributors. of center pivot and Involve designers who rely on a predetermined pressure for each sprinkler depending on the salinity of the water, this replacement is done every three to five years by the owners of the irrigation system.In 1992, about 92% of d Its irrigation water is drawn from non-renewable aquifers, which represents more than 85% of total national water consumption. As a result, the number of Piro irrigation systems in

Saudi

Arabia increased rapidly.

The centralized irrigation system may be efficient, but it doesn't really solve the problem it only postponed the problems the increase in irrigated areas led to a significant increase in pressure on

Saudi

Arabia's water supply and therefore problems of availability when the intense moder began an incredible agriculture of 120 cubic miles or 500 Under the desert there was enough cubic miles of water to fill Lake Erie in the US, but in recent years up to five cubic miles or 21 cubic kilometers on farms, virtually none of which is replaced by rainfall because there is actually none based on withdrawal rates found in a study from the School of Oriental in African Studies in London in 2004, the

s were on their way to use at least 96 cubic miles, or 400 cubic kilometers, of its groundwater supply by 2008.
Experts estimate that four qui Many parts of the sow's fossil water supplies are now depleted, even in

Saudi

Arabia, it has become part of the fertile land in modern times it became an arid desert, that was the case in albaida, about 20 miles south of bleating, the problem was that the inhabitants, the so-called Bedouins, were required by law to settle. in an area that leads to overgrazing and As the community gradually disappears, the community cut down trees to sell for charcoal and soon the once fertile land was reduced to a rocky desert. Deeper wells had to be dug for water as scant seasonal rains kept water in the ground from torrents that emptied into the Red Sea.
So instead of seeping into the ground and replenishing reserves, the government invited the scientist Stanford University permaculture scientist Nils Batman and Harvard University bioethicist and butturist Mona Handy to try to reverse the change Speckman lived through from 2010 to 2018. Albaida residents built rock terraces and dams Separate ditches and troughs on the ground to help collect rainwater Pacman and Handy use ancient Incan water-saving methods and local transportation to stop seasonal flooding and direct water to flow into useful streams. hardy trees. In 2015, Pac-Man and the Bedouins planted 10 species of trees, a total of 4,000 trees. Most of the trees died, but enough grew to raise hope for a green landscape that provides food for bees and animals.
The windbreak provides seeds. for oil and charcoal extraction l and improves the soil through nitrogen fixation when funding was withdrawn the project ran into problems and was abandoned for a few years but when the rains returned the trees sprouted again, maybe some One day everyone's success is emulated throughout
