Water shortages now. Is that many countries, particularly because of the importance of water as a key factor of human life is the one driving the economy? Whether it's water sector, agriculture, industrial use of electricity, etc. On the surface of the Earth Water covers two-thirds of the total area, but it appears that the world population. 1 in 5 are experiencing water shortages. Greater severity, impact and economic well being of those countries, such as India, China, the people's United States. The fact that the overall water quantity, the geography of the world, 97.5% is salt water to fresh water areas, only about 2.5% 2.5% fresh water ice, this is divided into South and North Pole-on mountain 30.8% 68.9% of ground water, and the water in the river and the Lake, also known as water on the surface of just 0.3%. At any time. The economic expansion and population growth. The need to use multiple high water. A severe water shortage crisis, respectively, until the leading up to the war, such as in Africa, water, usurp the population of over 200 million people. Severe water shortages are being encountered by the United Nations reports. More violence is expected. Expand a broad war 20-year tussle water front. Report to the United Nations within a year, 7 billion people from a population of over 2568 60 countries are experiencing severe water shortages. Water scarcity conditions: 10 important issues ... need to fix. Kasikorn Research Center study analyzed Thailand water shortages occur. At least 10 reasons as factors the accelerator caused shortages of water. Details as follows: 1. the climate change crisis to the current greenhouse gases. One greenhouse (Greenhouse Effect), the stress causes the temperature of the Earth rise called Global Warming has changed the season, some areas. 2. the problem of pollution in rivers, canals, and water sources, many countries now. Water pollution is experiencing various natural spoilage due to emissions from industrial waste water. Into water sources without treatment (water treatment), chemical residues from agriculture, mining. The litter and waste into water sources. 3. the increase in the population. This year. World population is approximately 7.2 billion people. Expected to increase roughly 80 million people. Within the end of this year. The increase in population makes demand for water is rising as well. Although the quantity of water that is used in everyday life, only 8% of fresh water is contained, compared the rate of agricultural and industrial sectors use water that is approximately 70% and 22%, respectively. 4. agricultural and livestock production sectors, agriculture and livestock expansion rate of water as high as possible about 70% of total water use in the world. From the use of chemical insecticides. Use of chemical fertilizer and animals near water source of water pollution in the construction caused both on land and under ground is harmful to consumers. 5. industrial growth than a few years ago. There are several extending investment industrial regions of the world. Especially in developing countries (Developing Countries) make use of more advanced water production steps. As a consequence, With the release of waste water, which is contaminated with chemicals into rivers, canals, causing water pollution cannot be consumed. 6. the lack of a good use of water management. These problems occur in every region of the country Thailand and the world. 7. underground water drilling. Ground water contained approximately 30.8% of fresh water in the world. The current drilling underground water even more. Drilling underground water is much larger. Cause effect is adversely seek water shovel on the ground dry knitted. In the end, will become a desert. 8. the creation of the dam are both productive and waste. The benefits of the dam to release water catchment using electricity sector, agriculture, etc. However, the creation of a system of dams affect the Environnment. To change the direction of flow of the water and make it lose many forest areas. 9. forests were destroyed. The world is facing the loss of many forest resources. The world's forest space. Rod is approximately 3 billion hectares (about 18.75 billion acres). The forest is destroyed, the forest is the river catchment is lost. Problems of water scarcity.
