121-623: Before the High Dam was built, even with the old dam in place, the annual flooding of the Nile during late summer had continued to pass largely unimpeded down the valley from its East African drainage basin . These floods brought high water with natural nutrients and minerals that annually enriched the fertile soil along its floodplain and delta ; this predictability had made the Nile valley ideal for farming since ancient times . However, this natural flooding varied, since high-water years could destroy

242-760: A "just solution" for the Palestinian refugees . The Peace Initiative was again endorsed at 2007 in the Riyadh Summit. In July 2007, the Arab League sent a mission, consisting of the Jordanian and Egyptian foreign ministers, to Israel to promote the initiative. Following Venezuela 's move to expel Israeli diplomats amid the 2008–2009 Israel–Gaza conflict , Kuwaiti member of parliament Waleed Al-Tabtabaie proposed moving Arab League headquarters to Caracas , Venezuela .

Through institutions, notably the Arab League Educational, Cultural and Scientific Organization (ALECSO) and the Economic and Social Council of its Council of Arab Economic Unity (CAEU), the League facilitates political, economic, cultural, scientific, and social programmes designed to promote

605-444: A growing period of almost one year. The high dam at Aswan releases, on average, 55 cubic kilometres (45,000,000 acre⋅ft) water per year, of which some 46 cubic kilometres (37,000,000 acre⋅ft) are diverted into the irrigation canals. In the Nile valley and delta, almost 336,000 square kilometres (130,000 sq mi) benefit from these waters producing on average 1.8 crops per year. The annual crop consumptive use of water

In 1966, the Roseires Dam was added to help irrigating the Gezira Scheme. The Jebel Aulia Dam on the White Nile south of Khartoum was completed in 1937 in order to compensate for

847-687: A million families were settled on these new lands. In particular the area under rice and sugar cane cultivation increased. In addition, about 1 million feddan (420,000 hectares), mostly in Upper Egypt, were converted from flood irrigation with only one crop per year to perennial irrigation allowing two or more crops per year. On other previously irrigated land, yields increased because water could be made available at critical low-flow periods. For example, wheat yields in Egypt tripled between 1952 and 1991 and better availability of water contributed to this increase. Most of

America and the United Kingdom offered to help finance construction of the High Dam, with a loan of $ 270 million, in return for Nasser's leadership in resolving the Arab-Israeli conflict. While opposed to communism, capitalism, and imperialism , Nasser identified as a tactical neutralist , and sought to work with both the U.S. and

The Arab League is rich in resources, such as enormous oil and natural gas resources in certain member states. Economic achievements initiated by the League amongst member states have been less impressive than those achieved by smaller Arab organisations such as

1210-513: A puzzle to scientists." A concern before the construction of the High Dam had been the potential drop in river-bed level downstream of the Dam as the result of erosion caused by the flow of sediment-free water. Estimates by various national and international experts put this drop at between and 2 and 10 meters (6.6 and 32.8 ft). However, the actual drop has been measured at 0.3–0.7 meters (0.98–2.30 ft), much less than expected. Flooding of

1331-674: A subsurface drainage system and approximately 7.2 square kilometres (2.8 sq mi) of water is drained annually from areas with these systems. The total investment cost in agricultural drainage over 27 years from 1973 to 2002 was about $ 3.1 billion covering the cost of design, construction, maintenance, research and training. During this period 11 large-scale projects were implemented with financial support from World Bank and other donors. The High Dam has resulted in protection from floods and droughts , an increase in agricultural production and employment, electricity production, and improved navigation that also benefits tourism. Conversely,

1452-497: A total of 2.1 gigawatts (2,800,000 hp). Power generation began in 1967. When the High Dam first reached peak output in 1970, it produced around half of Egypt's production of electric power (about 15 percent by 1998), and it gave most Egyptian villages the use of electricity for the first time. The High Dam has also improved the efficiency and the extension of the Old Aswan Hydropower stations by regulating upstream flows. At

The majority of the Arab League's citizens adhere to Islam , with Christianity being the second largest religion. At least 15 million Christians combined live in Egypt , Iraq , Jordan , Lebanon , Palestine , Sudan and Syria . In addition, there are smaller but significant numbers of Druze , Yazidis , Shabaks and Mandaeans . Numbers for nonreligious Arabs are generally not available, but research by

Due to the absence of appreciable rainfall, Egypt's agriculture depends entirely on irrigation . With irrigation, two harvests per year are possible, except for sugar cane which has

1815-548: Is a regional organization in the Arab world . The Arab League was formed in Cairo on 22 March 1945, initially with seven members: Egypt , Iraq , Transjordan , Lebanon , Saudi Arabia , Syria , and North Yemen . Currently, the League has 22 members . The League's main goal is to "draw closer the relations between member states and co-ordinate collaboration between them, to safeguard their independence and sovereignty, and to consider in

1936-425: Is about 38 cubic kilometres (31,000,000 acre⋅ft). Hence, the overall irrigation efficiency is 38/46 = 0.826 or 83%. This is a relatively high irrigation efficiency. The field irrigation efficiencies are much less, but the losses are reused downstream. This continuous reuse accounts for the high overall efficiency. The following table shows the distribution of irrigation water over the branch canals taking off from

2057-635: Is divided into five parts when it comes to transport, with the Arabian Peninsula and the Near East being entirely connected by air, sea, roads and railways. Another part of the League is the Nile Valley , made up of Egypt and Sudan . These two member states have started to improve the River Nile's navigation system to improve accessibility and thus foster trading. A new railway system is also set to connect

2178-535: Is essential to prevent a deterioration of crop yields from soil salinization and waterlogging. By 2003, more than 2 million hectares have been equipped with a subsurface drainage system at a cost from 1973 to 2002 of about $ 3.1 billion. Contrary to many predictions made prior to the Aswan High Dam construction and publications that followed, that the prevalence of schistosomiasis (bilharzia) would increase, it did not. This assumption did not take into account

2299-634: Is much lower. The Egyptian position changed completely after the overthrow of the monarchy , led by the Free Officers Movement including Gamal Abdel Nasser . The Free Officers were convinced that the Nile Waters had to be stored in Egypt for political reasons, and within two months, the plan of Daninos was accepted. Initially, both the United States and the USSR were interested in helping development of

2420-620: The Abu Simbel temples, were preserved by moving them to the shores of the lake under the UNESCO Nubia Campaign. Also moved were Philae , Kalabsha and Amada . These monuments were granted to countries that helped with the works: These items were removed to the garden area of the Sudan National Museum of Khartoum : The Temple of Ptah at Gerf Hussein had its free-standing section reconstructed at New Kalabsha , alongside

2541-510: The Ancient Egyptian religion , Hapi was the god of the Nile and the annual flooding of it. Both he and the pharaoh were thought to control the flooding. The annual flooding of the Nile occasionally was said to be the Arrival of Hapi . Since this flooding provided fertile soil in an area that was otherwise desert, Hapi symbolised fertility. The god Osiris was also closely associated with

However, they were still not able to retain sufficient water to cope with the driest summers, despite the Aswan Low Dam being raised twice, in 1907–1912 and in 1929–1933. During the 1920s, the Sennar Dam was constructed on the Blue Nile as a reservoir in order to supply water to the huge Gezira Scheme on a regular basis. It was the first dam on the Nile to retain large amounts of sedimentation (and to divert

2904-730: The Beirut Summit on 28 March 2002, the league adopted the Arab Peace Initiative , a Saudi-inspired peace plan for the Arab–Israeli conflict . The initiative offered full normalisation of the relations with Israel . In exchange, Israel was required to withdraw from all occupied territories , including the Golan Heights , to recognise Palestinian independence in the West Bank and Gaza Strip , with East Jerusalem as its capital, as well as

3025-592: The Delta Barrages and wide systems of new canals were built, changing the irrigation system from the traditional basin irrigation to perennial irrigation whereby farmland could be irrigated throughout the year. Thereby, many crops could be harvested twice or even three times a year and agricultural output was increased dramatically. In 1873, Isma'il Pasha commissioned the construction of the Ibrahimiya Canal , thereby greatly extending perennial irrigation. Although

Those of the Secretariat-General were agreed in May 1953. Since then, governance of the Arab League has been based on the duality of supra-national institutions and the sovereignty of the member states. Preservation of individual statehood derived its strengths from

While about 10 km of the water saved is lost due to evaporation in Lake Nasser, the amount of water available for irrigation still increased by 22 km. Other estimates put evaporation from Lake Nasser at between 10 and 16 cubic km per year. The dam powers twelve generators each rated at 175 megawatts (235,000 hp), with

Large-scale treatment programmes in the 1990s using single-dose oral medication contributed greatly to reducing the prevalence and severity of S. mansoni in the Delta. Sediment deposited in the reservoir is lowering the water storage capacity of Lake Nasser. The reservoir storage capacity is 162 km, including 31 km dead storage at the bottom of the lake below 147 m (482 ft) above sea level, 90 km live storage, and 41 km of storage for high flood waters above 175 m (574 ft) above sea level.

Dulles was angered more by Nasser's diplomatic recognition of China , which was in direct conflict with Dulles's policy of containment of communism. Several other factors contributed to the US deciding to withdraw its offer of funding for the dam. Dulles believed that

On the Egyptian side, the project was led by Osman Ahmed Osman 's Arab Contractors . The relatively young Osman underbid his only competitor by one-half. The Aswan High Dam is 3,830 metres (12,570 ft) long, 980 m (3,220 ft) wide at the base, 40 m (130 ft) wide at

5687-403: The High Aswan Dam, the floods could be controlled and the water could be stored for later release over multiple years. The Aswan Dam was designed by Nikolai Aleksandrovich Malyshev of the Moscow-based Hydroproject Institute . Designed for both irrigation and power generation , the dam incorporates a number of relatively new features, including a very deep grout curtain below its base. Although

5808-461: The High Dam has not created ecological problems as serious as some observers have charged, its construction has brought economic losses as well as gains. These losses derive largely from the settling in dam's lake of the rich silt traditionally borne by the Nile. To date (1971), the main impact has been on the fishing industry. Egypt's Mediterranean catch, which once averaged 35,000–40,000 tons annually, has shrunk to 20,000 tons or less, largely because

5929-485: The High Dam. When the Suez War broke out, the United Kingdom, France, and Israel seized the canal and the Sinai. But pressure from the U.S. and the USSR at the United Nations and elsewhere forced them to withdraw. In 1958, the USSR proceeded to provide support for the High Dam project. In the 1950s, archaeologists began raising concerns that several major historical sites, including the famous temple of Abu Simbel were about to be submerged by waters collected behind

6050-495: The Nile The flooding of the Nile (commonly referred to as the inundation) has been an important natural cycle in Nubia and Egypt since ancient times . It is celebrated by Egyptians as an annual holiday for two weeks starting August 15, known as Wafaa El-Nil . It is also celebrated in the Coptic Church by ceremonially throwing a martyr 's relic into the river, hence the name, The Martyr's Finger ( Coptic : ⲡⲓⲧⲏⲃ ⲛⲙⲁⲣⲧⲏⲣⲟⲥ , Arabic : Esba` al-shahīd ). The flooding of

The flooding of the Nile is the result of the yearly monsoon between May and August causing enormous precipitations on the Ethiopian Highlands whose summits reach heights of up to 4,550 m (14,930 ft). Most of this rainwater is taken by the Blue Nile and by the Atbarah River into

The British began construction of the first dam across the Nile in 1898. Construction lasted until 1902 and the dam was opened on 10 December 1902. The project was designed by Sir William Willcocks and involved several eminent engineers, including Sir Benjamin Baker and Sir John Aird , whose firm, John Aird & Co. ,

6413-414: The Nile Basin – most of which could have been predicted – it is a failure". Periodic floods and droughts have affected Egypt since ancient times. The dam mitigated the effects of floods, such as those in 1964, 1973, and 1988. Navigation along the river has been improved, both upstream and downstream of the dam. Sailing along the Nile is a favorite tourism activity, which is mainly done during the winter when

6534-466: The Nile Valley fluctuated 8–9 m (26–30 ft) per year with the water level of the Nile. During summer when evaporation was highest, the groundwater level was too deep to allow salts dissolved in the water to be pulled to the surface through capillary action . With the disappearance of the annual flood and heavy year-round irrigation, groundwater levels remained high with little fluctuation leading to waterlogging . Soil salinity also increased because

6655-403: The Nile and the fertility of the land. During inundation festivals, mud figures of Osiris were planted with barley. Arab League The Arab League ( Arabic : الجامعة العربية , al-Jāmiʿa al-ʻArabiyya , Arabic: [al.d͡ʒaː.mi.ʕa al.ʕa.ra.bij.ja] ), formally the League of Arab States ( Arabic : جامعة الدول العربية , Jāmiʿat ad-Duwal al-ʿArabiyya ),

6776-526: The Nile is about 134 million tons. This means that the dead storage volume would be filled up after 300–500 years if the sediment accumulated at the same rate throughout the area of the lake. Obviously sediment accumulates much faster at the upper reaches of the lake, where sedimentation has already affected the live storage zone. Before the construction of the High Dam, the 50,000 km (31,000 mi) of irrigation and drainage canals in Egypt had to be dredged regularly to remove sediments. After construction of

For example, the sardine catch off the Egyptian coast declined from 18,000 tons in 1962 to a mere 460 tons in 1968, but then gradually recovered to 8,590 tons in 1992. A scientific article in the mid-1990s noted that "the mismatch between low primary productivity and relatively high levels of fish production in the region still presents

His ideas of further reservoirs using Lake Victoria , Lake Albert and Lake Tana and of reducing the evaporation in the Sudd by digging the Jonglei Canal were opposed by the states concerned. Eventually, Gamal Abdel Nasser , President of Egypt from 1956 to 1970, opted for

During this short period, those rivers contribute up to ninety percent of the water of the Nile and most of the sedimentation carried by it, but after the rainy season, dwindle to minor rivers. The flooding as such was foreseeable, although its exact dates and levels could be forecast only on a short-term basis, by transmitting

7260-408: The U.S. would supply him with weapons only if they were used for defensive purposes and if he accepted American military personnel for supervision and training. Nasser did not accept these conditions, and consulted the USSR for support. Although Dulles believed that Nasser was only bluffing and that the USSR would not aid Nasser, he was wrong: the USSR promised Nasser a quantity of arms in exchange for

7381-501: The USSR for Egyptian and Arab benefit. After the UN criticized a raid by Israel against Egyptian forces in Gaza in 1955, Nasser realized that he could not portray himself as the leader of pan-Arab nationalism if he could not defend his country militarily against Israel. In addition to his development plans, he looked to quickly modernize his military, and he turned first to the U.S. for aid. American Secretary of State John Foster Dulles and President Dwight Eisenhower told Nasser that

7502-406: The USSR would not fulfill its commitment of military aid. He was also irritated by Nasser's neutrality and attempts to play both sides of the Cold War . At the time, other Western allies in the Middle East, including Turkey and Iraq, were resentful that Egypt, a persistently neutral country, was being offered so much aid. In June 1956, the Soviets offered Nasser $ 1.12 billion at 2% interest for

7623-426: The United States, the United Kingdom, and the International Bank for Reconstruction and Development (IBRD) withdrew their support in 1956. The first Soviet loan of $ 100 million to cover construction of coffer dams for diversion of the Nile was extended in 1958. An additional $ 225 million was extended in 1960 to complete the dam and construct power-generating facilities, and subsequently about $ 100 million

7744-418: The annual spread of sediment due to the Nile floods occurred along the banks of the Nile. Areas far from the river which never received the Nile floods before are now being irrigated. A more serious issue of trapping of sediment by the dam is that it has increased coastline erosion surrounding the Nile Delta. There is a lack of reliable statistics. Before the construction of the High Dam, groundwater levels in

7865-442: The basin irrigation method. Agricultural land was divided into large fields surrounded by dams and dykes and equipped with intake and exit canals. The basins were flooded and then closed for about 45 days to saturate the soil with moisture and allow the silt to deposit. Then the water was discharged to lower fields or back into the Nile. Immediately thereafter, sowing started, and harvesting followed some three or four months later. In

7986-541: The change to perennial irrigation. The dams also protected Egypt from the droughts in 1972–1973 and 1983–1987 that devastated East and West Africa. The High Dam allowed Egypt to reclaim about 2.0 million feddan (840,000 hectares) in the Nile Delta and along the Nile Valley, increasing the country's irrigated area by a third. The increase was brought about both by irrigating what used to be desert and by bringing under cultivation of 385,000 hectares (950,000 acres) that were previously used as flood retention basins. About half

On 26 July 1956, with wide Egyptian acclaim, Nasser announced the nationalization of the Suez Canal that included fair compensation for the former owners. Nasser planned on the revenues generated by the canal to help fund construction of

There are further emergency spillways for an extra 5,000 cubic metres per second (180,000 cu ft/s), and the Toshka Canal links the reservoir to the Toshka Depression. The reservoir, named Lake Nasser ,

8349-433: The dam flooded a large area, causing the relocation of over 100,000 people. Many archaeological sites were submerged while others were relocated. The dam is blamed for coastline erosion, soil salinity, and health problems. The assessment of the costs and benefits of the dam remains controversial decades after its completion. According to one estimate, the annual economic benefit of the High Dam immediately after its completion

8470-402: The dam should be torn down. Tearing it down would cost only a fraction of the funds required for "continually combating the dam's consequential damage" and 500,000 hectares (1,900 sq mi) of fertile land could be reclaimed from the layers of mud on the bed of the drained reservoir. Samuel C. Florman wrote about the dam: "As a structure it is a success. But in its effect on the ecology of

Weeds have been gradually brought under control by manual, mechanical and biological methods. Mediterranean fishing and brackish water lake fishery declined after the dam was finished because nutrients that flowed down

8712-487: The dam. A rescue operation began in 1960 under UNESCO (for details see below under Effects). Despite its size, the Aswan project has not materially hurt the Egyptian balance of payments . The three Soviet credits covered virtually all of the project's foreign exchange requirements, including the cost of technical services, imported power generating and transmission equipment and some imported equipment for land reclamation. Egypt

8833-589: The dam. Complications ensued due to their rivalry during the Cold War , as well as growing intra-Arab tensions . In 1955, Nasser was claiming to be the leader of Arab nationalism , in opposition to the traditional monarchies, especially the Hashemite Kingdom of Iraq following its signing of the 1955 Baghdad Pact . At that time the U.S. feared that communism would spread to the Middle East, and it saw Nasser as

8954-496: The damage inflicted on a main transformer station in 1968 by Israeli commandos has been repaired, and the Aswan plant is fully integrated with the power network in Lower Egypt. By 1971 estimation, power output at Aswan won't reach much more than half of the plant's theoretical capacity, because of limited water supplies and the differing seasonal water-use patterns for irrigation and power production. Agricultural demand for water in

9075-502: The distance between the surface and the groundwater table was small enough (1–2 m depending on soil conditions and temperature) to allow water to be pulled up by evaporation so that the relatively small concentrations of salt in the groundwater accumulated on the soil surface over the years. Since most of the farmland did not have proper subsurface drainage to lower the groundwater table, salinization gradually affected crop yields. Drainage through sub-surface drains and drainage channels

9196-409: The dry season thereafter, farming was not possible. Thus, all crops had to fit into this tight scheme of irrigation and timing. In case of a small flood, the upper basins could not be filled with water which could mean food shortages or even famine. If a flood was too large, it would damage villages, dykes and canals. The basin irrigation method did not exact too much of the soils, and their fertility

9317-532: The eastern portion of the occupied West Bank known as the Jordan Valley . The Arab League met in Cairo on 12 October 2019 to discuss Turkish offensive into north-eastern Syria . Upon meeting, its member states voted to condemn the Turkish offensive, dubbing it both an 'invasion' and an 'aggression' against an Arab state, adding that the organization saw it as a violation of international law. On 9 September 2020,

9438-404: The extent of perennial irrigation that was already present throughout Egypt decades before the high dam closure. By the 1950s only a small proportion of Upper Egypt had not been converted from basin (low transmission) to perennial (high transmission) irrigation. Expansion of perennial irrigation systems in Egypt did not depend on the high dam. In fact, within 15 years of the high dam closure there

9559-461: The founding treaty of the Arab League. Adopted in 1945, it stipulates that "the League of Arab States shall be composed of the independent Arab States that have signed this Pact." In 1945, there were seven members, but the Arab League now has 22 members, including 8 African countries: and 7 observer states (note: the observer states below have been invited to participate during select Arab League sessions but do not hold voting privileges): Egypt

9680-556: The idea of the Aswan High Dam at Aswan in Egypt instead of having to deal with many foreign countries. The required size of the reservoir was calculated using Hurst's figures and mathematical methods . In 1970, with the completion of the Aswan High Dam which was able to store the highest floods, the annual flooding cycle in Egypt came to an end in Lake Nasser . The Nile was also an important part of ancient Egyptian spiritual life. In

9801-527: The interests of the Arab world. It has served as a forum for the member states to coordinate policy, arrange studies of and committees as to matters of common concern, settle inter-state disputes and limit conflicts such as the 1958 Lebanon crisis . The League has served as a platform for the drafting and conclusion of many landmark documents promoting economic integration. One example is the Joint Arab Economic Action Charter , which outlines

9922-403: The large number of subsurface drainage projects executed in the last decades to control the water table and soil salinity . Drainage through subsurface drains and drainage channels is essential to prevent a deterioration of crop yields from waterlogging and soil salinization caused by irrigation. By 2003, more than 20,000 square kilometres (7,700 sq mi) have been equipped with

10043-483: The largest ethnic group in the Arab League, there are several other ethnic groups that also reside in the region, including Berbers , Kurds , Somalis , Assyrians , Armenians , Nubians , Mandaeans , and Circassians . Each of these groups have their own distinct cultures, languages, and traditions. As of 1 July 2013, about 359 million people live in the states of the Arab League. Its population grows faster than in most other global regions. The most populous member state

10164-522: The league's history, other smaller Arab Organizations have achieved more than the league has, such as the GCC , but lately several major economic projects that are promising are to be completed, the Arab Gas Pipeline is to end by 2010, Connecting Egyptian and Iraqi Gas to Jordan, Syria and Lebanon, and then to Turkey thus Europe, a free trade Agreement ( GAFTA ) is to be completed by 1 January 2008, making 95% of all Arab products tax free of customs. The Arab League

10285-486: The league. Each country was given one vote in the council. The first major action was joint intervention to keep Palestine from being divided into two states in keeping with the decision of the United Nations General Assembly. When Transjordan agreed to this proposal, Egypt intervened to prevent this from happening. It was followed by the creation of a mutual defence treaty two years later. A common market

10406-593: The loss of plankton nourished by the silt has eliminated the sardine population in Egyptian waters. Fishing in high dam's lake may in time at least partly offset the loss of saltwater fish, but only the most optimistic estimates place the eventual catch as high as 15,000–20,000 tons. Lack of continuing silt deposits at the mouth of the river also has contributed to a serious erosion problem. Commercial fertilizer requirements and salination and drainage difficulties, already large in perennially irrigated areas of Lower and Middle Egypt, will be somewhat increased in Upper Egypt by

10527-440: The month of June, when it reached its lowest level again. Flooding reached Aswan about a week earlier than Cairo, and Luxor five to six days earlier than Cairo. Typical heights of flood were 45 feet (14 metres) at Aswan, 38 feet (12 metres) at Luxor (and Thebes) and 25 feet (7.6 metres) at Cairo. Whilst the earliest Egyptians simply laboured those areas which were inundated by the floods, some 7000 years ago, they started to develop

10648-525: The nations can, therefore, no more be questioned de jure than the independence of any of the other Arab States. [...] Therefore, the States signatory to the Pact of the Arab League consider that in view of Palestine's special circumstances, the Council of the League should designate an Arab delegate from Palestine to participate in its work until this country enjoys actual independence At the Cairo Summit of 1964,

10769-469: The natural flow of the Nile would have been too low to allow navigation of cruise ships. A new fishing industry has been created around Lake Nasser, though it is struggling due to its distance from any significant markets. The annual production was about 35,000 tons in the mid-1990s. Factories for the fishing industry and packaging have been set up near the Lake. According to a 1971 CIA declassified report, although

10890-429: The natural preference of ruling elites to maintain their power and independence in decision making. Moreover, the fear of the richer that the poorer may share their wealth in the name of Arab nationalism , the feuds among Arab rulers , and the influence of external powers that might oppose Arab unity can be seen as obstacles towards a deeper integration of the league. Mindful of their previous announcements in support of

11011-466: The negative environmental and social effects of the dam, its costs are thus estimated to have been recovered within only two years. One observer notes: "The impacts of the Aswan High Dam (...) have been overwhelmingly positive. Although the Dam has contributed to some environmental problems , these have proved to be significantly less severe than was generally expected, or currently believed by many people." Another observer disagreed and he recommended that

11132-430: The nutrient value of the sediment has often been overestimated. 88 percent of the sediment was carried to the sea before the construction of the High Dam. The nutrient value added to the land by the sediment was only 6,000 tons of potash , 7,000 tons of phosphorus pentoxide and 17,000 tons of nitrogen. These amounts are insignificant compared to what is needed to reach the yields achieved today in Egypt's irrigation. Also,

11253-545: The old town of Wadi Halfa and its surrounding villages. Some were moved to a newly created settlement on the shore of Lake Nasser called New Wadi Halfa, and some were resettled approximately 700 kilometres (430 mi) south to the semi-arid Butana plain near the town of Khashm el-Girba up the Atbara River . The climate there had a regular rainy season as opposed to their previous desert habitat in which virtually no rain fell. The government developed an irrigation project, called

11374-460: The one main irrigation canal, the Mansuriya Canal near Giza. The salt concentration of the water in the Aswan reservoir is about 0.25 kilograms per cubic metre (0.42 lb/cu yd), a very low salinity level. At an annual inflow of 55 cubic kilometres (45,000,000 acre⋅ft), the annual salt influx reaches 14 million tons. The average salt concentration of the drainage water evacuated into

11495-594: The outbreak of the First Libyan Civil War . The Arab League voted to restore Libya's membership on 27 August 2011 by accrediting a representative of the National Transitional Council , which was the partially recognised interim government of the country. Syria was suspended on 16 November 2011 in the aftermath of the outbreak of the Syrian Civil War . On 6 March 2013, the Arab League gave

11616-412: The population diminished accordingly; by 1800, Egypt had a population of some 2.5 million inhabitants. Muhammad Ali Pasha , Khedive of Egypt (r. 1805–1848), attempted to modernize various aspects of Egypt. He endeavoured to extend arable land and achieve additional revenue by introducing cotton cultivation, a crop with a longer growing season and requiring sufficient water at all times. To this end,

11737-414: The principles for economic activities in the region. Each member state has one vote in the Council of the Arab League , and decisions are binding only for those states that have voted for them. The aims of the league in 1945 were to strengthen and coordinate the political, cultural, economic and social programs of its members and to mediate disputes among them or between them and third parties. Furthermore,

11858-536: The project is voluntary, and the army intervenes only at the request of one of the member states. Heightened military arsenal in many member states and, in a small minority, civil wars as well as terrorist movements were the impetuses for JAF's establishment. In the early 1970s, the Economic Council put forward a proposal to create the Joint Arab Chambers of Commerce across international states. That led to

11979-506: The reservoir will eventually silt in, even the most conservative estimates indicate the dam will give at least 200 years of service. The earliest recorded attempt to build a dam near Aswan was in the 11th century, when the Arab polymath and engineer Ibn al-Haytham (known as Alhazen in the West) was summoned to Egypt by the Fatimid Caliph , Al-Hakim bi-Amr Allah , to regulate the flooding of

12100-516: The rise of the river could be seen at the first of the cataracts of the Nile (at Aswan) as early as the beginning of June, and a steady increase went on until the middle of July, when the increase of water became very great. The Nile continued to rise until the beginning of September, when the level remained stationary for a period of about three weeks, sometimes a little less. In October, it often rose again and reached its highest level. From this period, it began to subside and usually sank steadily until

12221-489: The sea and the coastal lakes is 2.7 kilograms per cubic metre (4.6 lb/cu yd). At an annual discharge of 10 cubic kilometres (2.4 cu mi) (not counting the 2 kilograms per cubic metre [3.4 lb/cu yd] of salt intrusion from the sea and the lakes, see figure "Water balances"), the annual salt export reaches 27 million ton. In 1995, the output of salt was higher than the influx, and Egypt's agricultural lands were desalinizing . Part of this could be due to

12342-610: The setting up of mandates to promote, encourage and facilitate bilateral trade between the Arab world and significant trading partners. Following adoption of the Alexandria Protocol in 1944, the Arab League was founded on 22 March 1945. The official headquarters of the League was the Boustan Palace in Cairo. It aimed to be a regional organisation of Arab states with a focus to developing the economy, resolving disputes and coordinating political aims. Other countries later joined

12463-565: The signing of an agreement on Joint Defence and Economic Cooperation on 13 April 1950 committed the signatories to coordination of military defence measures. In March 2015, the Arab League General Secretary announced the establishment of a Joint Arab Force with the aim of counteracting extremism and other threats to the Arab States. The decision was reached while Operation Decisive Storm was intensifying in Yemen. Participation in

12584-543: The southern Egyptian city of Abu Simbel with the northern Sudanese city of Wadi Halfa and then to Khartoum and Port Sudan . The third division of the League is the Maghreb , where a 3,000 km stretch of railway runs from the southern cities of Morocco to Tripoli in Western Libya . The fourth division of the League is the Horn of Africa , whose member states include Djibouti and Somalia . These two Arab League states are separated by only ten nautical miles from

12705-527: The southern part of Sudan . It is referred to as the food basket of the Arab World , the region's instability including the independence of South Sudan has not affected its tourism industry, that is considered the fastest growing industry in the region, with Egypt , UAE , Lebanon , Tunisia , and Jordan leading the way. Another industry that is growing steadily in the Arab League is telecommunications. Economical achievements within members have been low in

12826-642: The summer far exceeds the amount needed to meet the comparatively low summer demand for electric power. Heavy summer irrigation use, however, will leave insufficient water under Egyptian control to permit hydroelectric power production at full capacity in the winter. Technical studies indicate that a maximum annual output of 5 billion kWh appears to be all that can be sustained due to fluctuations in Nile flows. Lake Nasser flooded much of lower Nubia and 100,000 to 120,000 people were resettled in Sudan and Egypt. In Sudan, 50,000 to 70,000 Sudanese Nubians were moved from

12947-634: The time of completion, it was the largest power station in Africa and the 6th largest hydroelectric power station in the world. All High Dam power facilities were completed ahead of schedule. Twelve turbines were installed and tested, giving the plant an installed capacity of 2,100 megawatts (MW), or more than twice the national total in 1960. With this capacity, the Aswan plant can produce 10 billion kWh of energy yearly. Two 500-kilovolt trunk lines to Cairo have been completed, and initial transmission problems, stemming mainly from poor insulators, were solved. Also,

13068-791: The two regions. The last division of the League is the isolated archipelago of the Comoros located off the coast of East Africa , which is not physically connected to any other Arab state, but still trades with other Arab League members. In collecting literacy data, many countries estimate the number of literate people based on self-reported data. Some use educational attainment data as a proxy, but measures of school attendance or grade completion may differ. Because definitions and data collection methods vary across countries, literacy estimates should be used with caution. United Nations Development Programme , Human Development Report 2010. The Persian Gulf region has had an oil boom , enabling more schools and universities to be set up. While Arabs constitute

13189-436: The whole crop , while low-water years could create widespread drought and consequently famine . Both these events had continued to occur periodically. As Egypt's population grew and technology increased, both a desire and the ability developed to completely control the flooding, and thus both protect and support farmland and its economically important cotton crop. With the greatly increased reservoir storage provided by

13310-452: Was E£ 255 million , $ 587 million using the exchange rate in 1970 of $ 2.30 per E£1 : E£140 million from agricultural production, E£100 million from hydroelectric generation, E£10 million from flood protection, and E£5 million from improved navigation. At the time of its construction, total cost, including unspecified "subsidiary projects" and the extension of electric power lines, amounted to E£450 million . Not taking into account

13431-471: Was "specifically designed to fail at producing the kind of greater collaboration and integration that might have weakened political leaders at home." The Arab League member states cover over 13,000,000 km (5,000,000 sq mi) and straddles two continents: Africa and Asia . The area largely consists of arid deserts, such as the Sahara . Nevertheless, it also contains several highly fertile lands like

13552-453: Was agreed to reinstate Syria's membership. The Arab League is a political organization which tries to help integrate its members economically, and solve conflicts involving member states without asking for foreign assistance. It possesses elements of a state representative parliament while foreign affairs are often conducted under UN supervision. The Charter of the Arab League endorsed the principle of an Arab nation-state while respecting

13673-519: Was called "New Nubia". Housing and facilities were built for 47 village units whose relationship to each other approximated that in Old Nubia. Irrigated land was provided to grow mainly sugar cane. In 2019–20, Egypt started to compensate the Nubians who lost their homes following the dam impoundment. Twenty-two monuments and architectural complexes that were threatened by flooding from Lake Nasser, including

13794-550: Was designed by Nikolai Aleksandrovich Malyshev of the Moscow-based Hydroproject Institute , along with some Egyptian engineers. 25,000 Egyptian engineers and workers contributed to the construction of the dams. Originally designed by West German and French engineers in the early 1950s and slated for financing with Western credits, the Aswan High Dam became the USSR's largest and most famous foreign aid project after

13915-515: Was established in 1965. The Arab League has not achieved much cooperation throughout its history. According to Michael Barnett and Etel Solingen , the design of the Arab League reflects Arab leaders' individual concerns for regime survival: "the politics of Arab nationalism and a shared identity led Arab states to embrace the rhetoric of Arab unity in order to legitimize their regimes, and to fear Arab unity in practice because it would impose greater restrictions on their sovereignty." The Arab League

14036-487: Was made available for land reclamation. These credits of some $ 425 million covered only the foreign exchange costs of the project, including salaries of Soviet engineers who supervised the project and were responsible for the installation and testing of Soviet equipment. Actual construction, which began in 1960, was done by Egyptian companies on contract to the High Dam Authority, and all domestic costs were borne by

14157-621: Was not seriously burdened by payments on the credits, most of which were extended for 12 years with interest at the very low rate of 2-1/2%. Repayments to the USSR constituted only a small net drain during the first half of the 1960s, and increased export earnings derived from crops grown on newly reclaimed land have largely offset the modest debt service payments in recent years. During 1965–1970, these export earnings amounted to an estimated $ 126 million, compared with debt service payments of $ 113 million. The Soviets also provided technicians and heavy machinery. The enormous rock and clay dam

14278-535: Was solid evidence that bilharzia was declining in Upper Egypt. S. haematobium has since disappeared altogether. Suggested reasons for this include improvements in irrigation practice. In the Nile Delta, schistosomiasis had been highly endemic, with prevalence in the villages 50% or higher for almost a century before. This was a consequence of the conversion of the Delta to perennial irrigation to grow long staple cotton by

14399-520: Was suspended from the Arab League on 26 March 1979 due to the Egypt–Israel peace treaty , with the League's headquarters moving from Cairo to Tunis , Tunisia. In 1987, Arab League states restored diplomatic relations with Egypt, the country was readmitted to the League in May 1989 and the League's headquarters were moved back to Cairo in September 1990. Libya was suspended on 22 February 2011, following

14520-431: Was sustained by the annual silt deposit. Salinisation did not occur, since, in summer, the groundwater level was well below the surface, and any salinity which might have accrued was washed away by the next flood. It is estimated that by this method, in ancient Egypt, some 2 million up to a maximum of 12 million inhabitants could be nourished. By the end of Late Antiquity , the methods and infrastructure slowly decayed, and

14641-724: Was the main contractor. In 1952, the Greek-Egyptian engineer Adrian Daninos began to develop the plan of the new Aswan Dam. Although the Low Dam was almost overtopped in 1946, the government of King Farouk showed no interest in Daninos's plans. Instead the Nile Valley Plan by the British hydrologist Harold Edwin Hurst was favored, which proposed to store water in Sudan and Ethiopia, where evaporation
