But, water is inexhaustible, inexhaustible? We can answer with certainty: no. Although 70.8% of the earth's area is covered by water, but 97.55% of the water is seawater, neither direct drinking nor irrigation. Of the remaining 2.5% of fresh water, less than 1% of the world's total fresh water can actually be utilized by mankind. It is true that from the primitive life on earth until now, water has been in the service of life, work hard, never stop. But I do not know if you have ever thought about: water patience is also a limit, today's water resources have been in short supply! There are two main reasons for this situation: first, the lack of nature itself; second, man-made destruction. Of course, we can't blame God for being unfair to us, giving us a water-starved planet; on the contrary, we should thank God for creating a beautiful home for us.
But, it is in this urgent situation, we human beings are still wasting and destroying water resources. As a result of a large amount of industrial wastewater discharged into the Lian, Yung two rivers, resulting in serious pollution of the water quality of the two rivers, the water quality is only up to the standards of the three categories, neither for drinking, nor can be used for irrigation; similar to Nan'ao such as the island counties, the water are dependent on the "God's arrangements" - all of the ponds and reservoirs including The rain catchment area of the flood diversion project only accounts for 31% of the total rain catchment area, and the water supply for industrial and agricultural production and people's living is still difficult. From this we can see that it is urgent to deal with the problem of pollution and destruction of water resources. However, there is a serious shortage of water resources in the world today, and the number of wars triggered by water is increasing day by day. For example, of all the resources in the Middle East, the one that is most likely to cause a crisis is water, which is more expensive than oil in the Middle East. The vast majority of countries in the Middle East suffer from serious water shortages, and the Middle East has been in drought for more than a decade, facing a serious water crisis. The small Jordan River has given birth to two major religions, is the Middle East's most fiercely contested water source, the Middle East four major wars are related to it. Jordan pool for Israel's main source of water - Lake Galilee to provide two-thirds of the water. 1955 Johnston agreement stipulates the amount of water for all parties, but only Israel signed, the Arab countries in the 1960s to intercept the Jordan River. 1965, the Israeli army blew up the Syrian interceptor, the Arab-Israeli both have the destruction of the competition for each other's water resources as the primary strategic goal, Israel has the destruction of the competition for each other water resources as a primary strategic goal, and Israel occupied the Golan Heights, where the Jordan River originates. One of the difficulties in the Syrian-Israeli negotiations is Israel's insistence on taking possession of the vast majority of the West Bank's water resources. Currently, water resources in the West Bank are under Israeli control, with per capita water consumption three quarters that of Jewish settlers, while payments are two times higher. The water quality has deteriorated as a result of the over-pumping of groundwater, which in the Gaza Strip has become saline and unusable, and the lack of water has been exacerbated by the lack of management of water resources in the Strip since the violent conflict.
Three major water systems in the Middle East, along the rocky countries so far no comprehensive agreement to share water resources, disputes continue. The Nile River flows through 10 countries, due to the upstream Egypt is affected. Egypt's construction of the Aswan Dam, the country's water problems have been resolved, but caused the dissatisfaction of the upstream countries. A dispute, the Sudan will threaten to cut off the flow, Ethiopia and the Sudan in 1991 signed an agreement to take 4 billion tons of river water per year, Egypt is strongly opposed to Turkey's abundant water resources, Turkey built the water south to reduce the flow to Syria and Iraq by the two countries of the strong opposition. Turkey and Israel reached an agreement, the Manavgat River water with the world ship to Israel Jordan and Syria are also considering purchasing water from Turkey. Turkey wants to play the role of a water power to promote cooperation and stability in the Middle East. Israel wants Turkey*** to increase its water supply to Syria. in exchange for Syrian concessions on the Lake Gali border, but Turkey lets its daunted by the complex Arab-Israeli dispute and refuses to get involved.
It is clear that to use the right to water shortages for a period of time to be buffered. Is very not easy. The only way is to conserve water, and in this regard, Israel has done relatively well. Israel's 2/3 of the country are desert, seven months of the year without rain, per capita water resources of nearly 70 cubic meters, less than 1/4 of the Middle East, the world's per capita 3%, China's per capita 1/8. However, it is this piece of barren water-scarce land, Israel relies on the scientific use of water, built the modernization of agriculture, the world marveled.
Agriculture was Israel's founding of the country, in 1952, Israel to spend 1, 500 million U.S. dollars, took 10 years to build a 145-kilometer "north-south water transfer" pipeline, the mid-1960s to promote the scientific use of water drip irrigation methods, led to the take-off of the agricultural economy. Israel's agricultural population from 60% down to 3%, a farmer can feed 90 people, GDP per capita 18,000 U.S. dollars, jumping to the world's top 12. Israel greatly treasures water resources and regards water as a lifeline, and water conservation is a systematic process involving all aspects of society. As a result, success has been achieved.
