Fresh water, sea water, ice, groundwater, rainwater: there are about 138.6 x 108 billion cubic meters of water on Earth. However, there are 1.5 billion people on Earth who lack drinking water. Moreover, the number of people on earth who lack drinking water is likely to reach as many as 2 billion by 2050. According to statistics, there are currently 20 of the world's most water-stressed countries.
Among the most water-scarce countries, Malta's annual per capita water availability is only 82 cubic meters, and its degree of water scarcity ranks first among water-scarce countries.
In terms of population projections based on UN assumptions, by 2050 Libya will be at the top of the list of water-scarce countries (it was the fourth most water-scarce in 1995), with an annual per capita availability of only 31 cubic meters.
In another 50 years, Malta, whose population is growing less rapidly, will become the fourth most water-scarce country, with a national per capita availability of 68 cubic meters.
In 1995, in addition to Malta, the most water-scarce countries were Qatar, Kuwait, Libya, Bahrain, Singapore, Barbados, Saudi Arabia, Jordan, Yemen, Israel, Tunisia, Algeria, Burundi, Cape Verde, Oman, the United Arab Emirates, Egypt, Kenya and Morocco.
Many experts say water will be more valuable than oil in the 21st century. It has already been discovered that water is not as abundant in the major oil-producing countries. This situation will not improve by 2050. However, oil-producing countries have a lot of cheap energy, which could enable them to work on desalination.
In another 50 years, Kuwait, Qatar, Saudi Arabia, Bahrain, Oman and Algeria will be the second, third, fifth, seventh, eleventh and fifteenth most water-stressed countries, respectively. Only the United Arab Emirates and Morocco will no longer be among the most water-scarce countries. But Somalia and Rwanda, two other countries that were not previously among the most water-scarce, will become new water-scarce countries and will be the 17th and 18th most water-scarce, respectively.
According to the Association for Teasing Balance and Population Land, the annual per capita possession of less than about 1,700 cubic meters of water is the eve of water scarcity, and less than 1,000 cubic meters is the eve of chronic water scarcity, according to the Association for Teasing Balance and Population Land.

Is China one of the thirteen countries in the world with the most water scarcity
The countries and regions of the world differ greatly in the amount of water resources they possess because of their different geographic environments. Ranked by the amount of water resources, the top few are, in order: Brazil, Russia, Canada, China, the United States, Indonesia, Bangladesh and India. When averaged over the population, it's a different story. China's per capita water resources is only 1/4 of the world's per capita amount. 65% of the world's freshwater resources are concentrated in 10 countries, while 80 countries, accounting for 40% of the population, suffer from serious water shortages. If a country has less than 2,000 cubic meters of water per capita per year, it is a water-scarce country. Those with less than 1,000 cubic meters of water per capita are severely water-scarce countries, of which there are 15. China is not rich in water per capita and is one of the water-scarce countries. Human demand for water is increasing day by day. The world's water consumption in 1975 was 3 trillion cubic meters, and in 2000 it was 7 trillion cubic meters. Some people analyze that after 2030, the world's water resources will be in short supply; in 2050, there will be a water deficit of 230 billion cubic meters; in 2070, there will be a water deficit of 410 billion cubic meters. Our experts analyze that China's total water demand in 2050 will be 800 billion cubic meters, an increase of 240 billion cubic meters over the present.

By then, Malta, whose population is growing less rapidly, will become the fourth most water-scarce country, with a national per capita availability of 68 cubic meters.

Water scarcity around the world
June 5 is World Environment Day 2003, and this year's theme is "Water - the key to the lives of 2 billion people! ". Relevant statistics show that 2 billion people around the world are currently facing water shortages, 3 billion people lack access to water sanitation facilities, and 3 to 4 million people die of water-related diseases every year. By 2025, the water crisis will have spread to 48 countries around the world and 3.5 billion people will face severe water shortages. Pictured on June 1, villagers in the Indian state of Gujarat are fetching water from a huge local well. At present, Gujarat is experiencing a rare drought in more than a decade, the hot sun, the local residents of the water has become a problem. Some other areas in India are also experiencing drought. Xinhua Stockholm, August 13 (Reporter Wu Ping) some famous international water experts in Stockholm International Water Resources Symposium on the 13th in the opening speech, called on the world to carry out cross-field cooperation to solve the increasingly serious global water shortage. Margaret Catley Carlson, chair of the Global Water Collaboration, said that in the face of increasingly scarce water resources, the world is facing the challenges of population growth, lack of funds and outdated concepts in three major areas, and that only by all parties, including government departments, scientific research institutes, local organizations and private enterprises **** the same efforts, it will be possible to find solutions to the problem. Won this year's Stockholm Water Prize Professor Takashi Asano of the University of California said that the current water shortage faced by mankind is largely man-made, because a large number of valuable water resources can not be fully utilized in vain, such as the serious industrial water waste phenomenon. He believes that industrial water consumption can be reduced by 40 to 90 percent if effective technologies are used. According to a study published by the International Water Management Institute (IWMI), more than 450 million people around the world*** are currently facing serious water shortages. If no action is taken, the number of people in the world suffering from severe water shortages will surge to 2.7 billion in 25 years. The Stockholm International Water Symposium was attended by more than 1,000 water experts and government officials from around the world.
