The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development. 70% of this demand derives from agriculture which shows the influence of water on food supply globally as well not just drinking water (Sawin “Water Scarcity could overwhelm the Next Generation”). But increasing water use is not just a matter of the greater number of people needing it to drink and eat; it also comes from pollution and misuse of water supplies, by either dumping or runoff of bacteria or chemicals into water. This also “causes other pollutions as well such as soil and air pollution, accelerating wetland damage and human caused global warming” (Smith and Thomassey 25). According to UN report, recent estimates suggest that climate change will account for about 20 percent of the increase in global water scarcity in coming decades.
One main causes of water scarcity is water mismanagement worldwide. Water mismanagement has become a crisis of governance that will impact heavily ...

- ... Of that 3 percent, the vast majority is used for agricultural (70 percent) and industrial (22 percent) purposes. Less than 1 percent of the world’s freshwater is readily accessible for human use (drinking, cooking, and hygiene). (Rights, 9) There is so much water in the world, but most of the water is saltwater that we cannot use. Then even the water we can use is 3 percent of how much water there is in the world. Now with China, India, and the United States being affected by the water scarcity, they will also be affected by the impact of not producing enough grain.... [tags: global, contamination,aquifers]

- An immerging issue is the one that has appeared in the past few years. Water shortage is not something most people in developed countries think about. People in developed countries use thousands of gallons of water every day and do not even stop to think about it. This is because it is cheap and readily available. This is a completely different story in developing countries where the people there have to walk miles on end to get a pale of water. The people in these unfortunate countries use very little water every day because to them water is sacred.... [tags: water shortage, developing countries, clean water]

- "Environmental factors are more significant in explaining water scarcity than human factors." Discuss. Water is one of the most vital resources to a human that there is. 70% of the Earth is covered by water but only 3% of that is fresh and able to be consumed. When it is taken into account that roughly two thirds of that fresh water is trapped in ice at Antarctica it shows how little water we actually have. According to research, some 1.1 billion people worldwide lack access to water and a further 2.7 billion find water to be scarce for at least one month per year....

- When the question is asked “what is the biggest problem in the world”, to many the first that comes to mind is possibly war, education, or even climate change. But unshockingly, the revelation is that the world’s biggest problem at this moment is neither war, nuclear warfare, or even the supposed apocalypse brought about by global warming. According to the European Union, it’s the lack of drinking water. But with all the propaganda raising awareness of the issue, why is this still a problem. Celebrities and organizations around the world pool together millions of dollars into these projects every year yet, somehow every 29 seconds a child somewhere is dying due to contaminated water....

- Water is vital for humanity as it sustains human life and is a fundamental aspect in most of the products which are consumed by an average living person. This is why water supplies are crucial, because through them this substance is provided sadly these services are being perturbed by various obstacles that at the end are provoking a severe water scarcity around the globe. This has been attempted to be solved by privatising water services, since it is believed that water available for free has generated an overexploitation of this resource....

- Introduction A major part of the world we live in, as well as our bodies, consist of water. Since it is a restricted source, the preservation of clean water and its adequate distribution throughout the planet is extremely vital. However, today 783 million people lack access to improved water sources. Many countries are still struggling to reach the water-related objectives of the Millennium Development Goals – threatening their advancement and ecological maintainability – and millions of people die each year from treatable waterborne diseases....

- “Water is the lifeblood of this planet. Every time a good is bought or sold there is a virtual exchange of water. Every time we interact with water, we change it, redirect it, or otherwise alter its state. We have never learned how to efficiently manage water.”(Cluckie, 2009) Ian Cluckie, Professor of Hydrology and Water Management, emphasizes the fact that humans can’t survive without water. Although water is a renewable resource that can replenish under hydrological cycles, our intervention has interrupted its natural cycle causing its supply to decrease.(Cluckie, 2009) The value of water is constantly being compared to diamonds....

- Dripping Water Have you ever experienced water shortage. Have you ever paid to access public areas. Have you ever seen a brown river. Welcome to Lebanon. “Thousands have lived without love, none without water” (Auden, 1940). The genuine predicament lies in the mismanagement of the water resources, not in the amount of available water in Lebanon. As the international population is growing, the need for water is increasing at the same rate. Therefore, it is essential to manage the remaining resources rationally for the better of the international community.... [tags: Water, Water supply, Water resources]

- “Agriculture is a major user of ground and surface water in the United States, accounting for 80% of the Nation's consumptive water use and over 90% in many Western States” (“Irrigation and Water Use”). As population grows, our demand for food and agriculture also grows. Therefore, we need a more efficient irrigation system. In “U.S. to tighten tap for farmers”, Bloomekatz mentioned that the government had reduced or even refused to supply water to some agriculture fields in 2009. In Central Valley, the government had refused to provide water for over 200 water districts.... [tags: Drinking Water Scarcity]
