Irrigation in Saudi Arabia

Irrigation in Saudi Arabia is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Irrigation in Saudi Arabia rather than just read about it. In short: Center pivot irrigation in Saudi Arabia is typical of many isolated irrigation projects scattered throughout the arid and hyper-arid regions of the Earth. Nonrenewable fossil water is mined from depths as great as 1 km (3,000 ft), pumped to the surface, and distributed via large center pivot irrigation feeds.

Key takeaways

Irrigation in Saudi Arabia belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Irrigation in Saudi Arabia to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Irrigation in Saudi Arabia from memory before moving on to harder problems.

Reference excerpt

Center pivot irrigation in Saudi Arabia is typical of many isolated irrigation projects scattered throughout the arid and hyper-arid regions of the Earth. Nonrenewable fossil water is mined from depths as great as 1 km (3,000 ft), pumped to the surface, and distributed via large center pivot irrigation feeds. The circles of green irrigated vegetation may comprise a variety of agricultural commodities from alfalfa to wheat. Diameters of the normally circular fields range from a few hundred meters to as much as 3 km (1.9 mi). The projects often trace out a narrow, sinuous, and seemingly random path. Actually, engineers generally seek ancient river channels now buried by the sand seas. The fossil waters mined in these projects accumulated during periods of wetter climate in the Pleistocene glacial epochs, between 10,000 and 2 million years ago, and are not being replenished under current climatic conditions. The projects, therefore, will have limited production as the reservoirs are drained.

A network of dams has been built to trap and use precious seasonal floods. Vast underground water reservoirs have been tapped through deep wells. Desalination plants have been built to produce fresh water from the sea for urban and industrial use, thereby freeing other sources for agriculture. Facilities have also been put into place to treat urban and industrial run-off for agricultural irrigation. These efforts collectively have helped transform vast tracts of the desert into fertile farmland. Land under cultivation grew from under 400,000 acres (1,600 km2) in 1976 to more than 8 million acres (32,000 km2) in 1993. Saudi Arabia is suffering from a major depletion of the water in its underground aquifers and a resultant break down and disintegration of its agriculture as a consequence. As a result of the catastrophe, Saudi Arabia has bought agricultural land in the United States, Argentina, and Africa. Saudi Arabia ranked as a major buyer of agricultural land in foreign countries.

International Cooperation The cooperation between the Saudi Irrigation Organization (SIO) and Food and Agriculture Organization (FAO) is based on strengthening national capacities in irrigation systems' management and improving water-use efficiency in the agricultural sector through technical and advisory collaboration. This partnership aims to promote the adoption of efficient irrigation technologies, develop a national code for irrigation practices, assess and improve the performance of irrigation networks and canals, and implement training programs and awareness sessions for farmers and agricultural sector personnel on modern irrigation technologies and sustainable practices. This cooperation has been reflected through the launch of intensive training programs and the organization of joint field visits to review projects and initiatives aimed at rationalizing water consumption and enhancing agricultural productivity.

Worked examples

Example 1 — a first encounter with Irrigation in Saudi Arabia

Start with the simplest possible case. Write down what Irrigation in Saudi Arabia claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Irrigation in Saudi Arabia before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Irrigation in Saudi Arabia ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Irrigation in Saudi Arabia

In research: Irrigation in Saudi Arabia appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Irrigation in Saudi Arabia in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Irrigation in Saudi Arabia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agriculture in Saudi Arabia, Irrigation by country, Water supply and sanitation in Saudi Arabia, so understanding it makes those chapters shorter.
In everyday life: Look for Irrigation in Saudi Arabia outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
