1985 the meteorological and public safety

March 22, 2007 is the fifteenth session of the carry out the and local levels for sustainable water resources shortage, effective and just treatment.
order apt alleviate the globe water supply and demand, along to the United Nations , given the shortage of universal freshwater resources, not merely in many countries will presently fall into the plight of water, economic evolution ambition be restricted, January 18, 1993, the 47th United Nations General Assembly passed a resolution to decide the 22 March each annual as World Water Day is the ideal life-sustaining liquid. mammalian body is 60-65% water, human body heaviness of 2 / 3, 99% of the head, bones are too 44% water. According to estimates of hydrological geographers, world The total amount of approximately 1.38 billion cubic kilometers of water, of which 97.5% is sea water (1.345 billion cubic kilometers). the world's fresh water resources list as merely 2.5% of the aggregate amount of water, and in this infrequent freshwater resources, there More than 70% is frozen in the Antarctic and Arctic ice hats, coupled with tough to use sleet mountain glaciers and permafrost, 87% of freshwater resources is tough to use. people creatures truly accessible freshwater resources in rivers, lakes and groundwater portion of the total amount of water almost 0.26% of the Earth. a long time, the human mind has a erroneous concept that water seems to be inexhaustible, merely in truth it is very finite water resources . with the social evolution, population growth, irrational use and environmental pollution, human demand for water increasing, but the water available for human use has been instantly diluted, depletion of freshwater resources on the brim of a emergency.
Water is the existence of all living entities, the foundation for development, not only in the Water Day, we tin calculate of spliced to the water, saving water, to make our lives each day to chance will be a desolate woods will stop to exist, plants will dead, the Earth will emerge infinite miles of desert, all life will cease to exist, signs of life will vanish, mankind will not survive.
lack of water Resources
countries are facing many of the world water crisis: water shortages 1.2 billion people, 3.0 billion people lack water sanitation facilities each year 3000000-400 million people die of water-related diseases. data show that the world by region delivery, Brazil, Russia, Canada, China, the United States, Indonesia, India, Colombia and the Congo and other 9 countries of the world's freshwater resources accounted for 60% of freshwater resources. about 40% of the total world population in 80 countries and regions in a serious shortage of water. 20th century, 50 years after the world's rapid population growth, rapid industrial development. On the one hand, the human demand for water to amplify at an agitating rate; the other hand, dining a lot more serious water pollution of water resources for expense. With population growth, irrational use and pollution, the source of life on Earth is gradually drained. According to March 2003, held in Kyoto, Japan, the Third World Water Forum UN World Water Assessment Report showed that for every world day about 200 tons of garbage dumped in rivers, lakes and streams, 8 liters per liter of wastewater will taint the water; all the rivers flowing through cities are dirty in Asia; the United States 40% of the water basin is processed food garbage, metals, fertilizers and pesticide pollution; 55 rivers in Europe only five water quality was poor. According to United Nations statistics, about 11 million people a day without neat water, about 6,000 children a day die from unsafe water and sanitation failure caused by the disease. With the increased damage caused by water pollution, World water crisis not only hinder the sustainable development, but also intimidate world truce, the quondam 50 years, the conflict caused by water from a total of 507, of which 37 had its violent ecology, 21, turned into a naval conflict since. experts advise that, with the increasingly scanty water resources, water, intensified rivalry for knight.
serious water shortage in China is an arid nation. fresh water resources total 2.8 trillion cubic meters, accounting for 6% of global water resources, but only 2300 cubic meters per capita,aboard April 22, world average of only 1 / 4. in consecutive years, the World Bank statistics, ranks 132 countries in 82. to the 20th century, more than 600 cities in the nation, more than 400 cities in the problem of inadequate water supply exists, the extra serious water up to 110 cities.
also an important element in exacerbating the water crisis, for maximum of fresh water from precipitation. In the context of global warming, extreme weather accidents, the probability and intensity of will mushroom. CMA Regional Meteorological Centre in Chengdu of Sichuan and Chongqing specialists in the dry and warm climate in winter was diagnosed and evaluated, experts say: In 2006, the dry and warm spring weather is occasioned along caustic drought in Sichuan and Chongqing, the chief zone. According to the Meteorological file inquiry, the impact deserving to the lukewarm, highly regarded, Sichuan, Chongqing, ranking History winter temperatures over the same time, respectively, the fourth, 3 tall merit of the year. Sichuan, Chongqing, the average winter temperature in the same period were higher than the regular 1.1 ℃, 1.2 ℃; in 2006 seasoned hot and dry summer followed at large experience drier winter and spring of this year, the keen problem of serious shortage of rainfall, drought still continued follow-up effects, resulting in construction of water cache and water warehouse was less than natural rice fields, rivers and water generally in the lowest water level roaming, the water chart is falling quickly. As of March 9, 41 zones and counties beneath the jurisdiction of Chongqing, only five counties are not subject to drought, the metropolis place of ​​136 thousand hectares of harvests affected by the drought, now 34 areas in Chongqing About 140 million human in the county drinking water problems exist.
