One of the biggest challenges facing the world is availability of fresh water. Only about one third of a percent is of the fresh water available on earth is found in surface and ground water for human consumption. Globally these sources of fresh water have been dwindling away and becoming scarcer every year as water demand grows. This problem is true throughout the world and is especially prevalent in the arid regions of the world such as the Southwest United States. Since I am a student here at the University of Arizona and a resident of the state now, these growing water issues not only affect me but all of the residents of Tucson, Arizona. This makes water sustainably critical to the entire region and me. …show more content…

The few rivers and lakes that exist do not contain a sufficient supply of water to meet the demand of the populace. This requires the majority of the water that is supplied to come from groundwater. Ground water is a series of aquifers, springs, and wells that store water beneath the surface. These underground water resources take time to accumulate because they are filled by surface runoff that has to seep through pores and crevices in soil, sands, and rock. In arid climates it takes even longer to accumulate because of the lack of precipitation each year. At the current rate of ground water pumping the water that is being pumped out of aquifers and springs is greater than it is replenished naturally. With population expected to grow in Tucson and around Arizona the groundwater depletion will only continue to

  • Water Consumption In Phoenix

    687 Words  | 2 Pages

    Increase in water consumption is a topic usually discussed inasmuch as this problem affects many cities. Phoenix is located in the State of Arizona, with around 540 square miles. Moreover, according to official site of City of Phoenix, the city ranks as one of the fastest-growing cities in the nation with approximately 1.4 million people. The city of Phoenix, although it is being in an arid area, has a per capita consumption lower than expected. The consumption of water is essential for life; however, what have to be analyzed is the withdrawal of water; furthermore, the capacity of regeneration of water resources mainly for future generations, which is the concept of sustainability. There are many aspects that would influence the consumption of water; however, each city has its own particularities. Although, Phoenix when analyzed as totality does not have an excessive consumption; it is a peculiar city and if an analysis is done in small scale, such as neighborhood, it is possible to identify the major consumer of water. “Determinants of residential water demand reflect both indoor and outdoor use and including size of the houses, if the houses have swimming pools, lot size, and the prevalence of gardens and vegetation that require water.” (Elizabeth A. Wentz & Patricia Gober, 2007). In addition, according to Phoenix City, since 1881, when the city was officially incorporated, until today’s date, the city of Phoenix has been improving its own capacity to provide water for the population. Phoenix can reach 2.2 million people by the 2030 (Census Boreau, 2010). A challenge for the future is to find new resources to provide water for the population even in severe drought.

  • Water Scarcity in the USA

    985 Words  | 2 Pages

    Over the past fifty years, the U.S. population has doubled in size. During this time, total water usage per person has almost tripled. Since the end of World War II, there has been a steady increase of people moving out of rural areas and into cities. As a result, the domestic self-supplied population has greatly decreased and the need for public-water supply systems has intensified. These factors, in conjunction with certain economic trends, precipitation, and global climate changes, pose difficult challenges in the years to come.

  • Mexico City Water Shortage

    1575 Words  | 4 Pages

    Caused by climate change and urbanization, water shortages are a major concern of the Mexican government at both the local and federal level. Mexico City, the third largest city in the world with more than twenty million inhabitants, struggles with water scarcity because of the potential risk it poses to the wellbeing of its citizens. Similar to the situation in other megacities, such as Jakarta and Bangkok, Mexico City’s water supplies are being depleted because of a growing urban population. (CBC News , 2009 ) Unable to sufficiently supply the increasing population size of the city, the water in the Mexico Valley aquifer is being drawn out faster than the aquifer’s recharge rate. Exacerbated by the fragmented nature of Mexico’s political culture, the exploitation of Mexico City’s water resources due to a growing urban population is detrimentally degrading the environment and creating a self-perpetuating problem that places the city and its inhabitants at risk.

  • The Ogallala: Preserving the Great American Desert

    1871 Words  | 4 Pages

    Long ago, the middle of the North American continent was a treeless prairie covered by tall grasses and roaming buffalo. When European settlers came, they called this area the Great American Desert. Today, this "desert" is covered with fields of wheat, corn, and alfalfa made possible by center-pivot irrigation. My grandfather used to sell center-pivot systems and when my family drove to my grandparent's home in Nebraska, we would count how many "sprinklers" were watering each section of land. At the time, I didn't know that this water was being pumped from somethng called the Ogallala Aquifer, a huge underground water supply. Throughout the years, this aquifer has made the Great American Desert one of the best farming areas in the world. Unfortunately, the Ogallala Aquifer's future as a valuable resource is in jeopardy, unless citizens of the Plains states reduce their water consumption.

  • The Water Shortage in Mexico

    989 Words  | 2 Pages

    Mexico is high-urbanized country. Almost 78% of its citizens live in cities (Castro and Heller 2009). That is why citizens of urban areas suffer the most from the appreciable water shortage. The situation with water supply in urban areas is critical. As an example, Mexico City, with population about 20 million people, faces quite serious scarcity of water. It obtains water from 3 main basins, all of them are overexploited (UNESCO 2006). The solution of the government to this problem was to pump water from the aquifers. However, these palliative actions of the government have not solved the problem, three aquifers from which city gets water are overused (UNESCO 2006).

  • Las Vegas's Water Shortage

    717 Words  | 2 Pages

    Groundwater remained the main supply until 1971 which was when Las Vegas became more dependent on Colorado River water due to the “Southern Nevada Water System” (Brown, n.d.; Larsen et al., 2015). Since then up to 90,000 acre-feet of groundwater has been pumped on a yearly basis, this value surpasses the natural groundwater recharge (Laczniak et al., n.d.). Rain as well as snow serves as the primary sources of groundwater recharge for the aquifers while precipitation plays a minor role (Laczniak et al., n.d.). Due to there not being balanced discharge and recharge this has led to subsidence and as a result of this subsidence the storage capacity of aquifers has decreased due to compaction (Laczniak et al., n.d.). It is estimated that 187,000 acre feet of storage capacity in the aquifers has been lost due to compaction (Laczniak et

    Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.

  • The Water Crisis and Solutions

    1481 Words  | 3 Pages

    Freshwater is quite scarce, but it is even scarcer than one might think: about seventy percent of all freshwater is frozen in the icecaps of Antarctica and Greenland and is unavailable to humans. Most of the remainder is present as soil moisture or lies in deep underground aquifers as groundwater. It is not economically feasible to extract this waster for use as drinking water. This leaves less than one percent of the world’s fresh water that is available to humans. It includes the water found in lakes, reservoirs, groundwater that is shallow enough to be tapped at an affordable cost. These freshwater sources are the only sources that are frequently replenished by rain and snowfall, and therefore are renewable. At the current rates of consumption, however, this supply of fresh water will not last. Pollution and contamination of freshwater sources exacerbate the problem, further reducing the amount of freshwater available for human consumption. Something must be done if humans want to even survive in the near future: the lack of clean drinking water is already the number one cause of disease in the world today. The first step is worldwide awareness of the water crisis: governments and the citizens they govern worldwide need to know about this problem and be actively involved in solving this problem.

  • The Problem of Water Scarcity

    1538 Words  | 4 Pages

    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.

    Freshwater in the world makes up only a small portion of the water on the planet. While the percentage of water in the world is nearly 70%, only 2.5% is consumable. Even further, only 1% is easily accessible to basic human needs. According to National Geographic, “by 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change.” With this current trend, water will become more immersed in environmental, economic, political, and social changes.

    Many people around the world need water. Around 780 million people are unable to get clean water (One Billion Affected). People who do have access to clean water in their homes, have to pay a fee. The people who struggle to live obviously do not have enough money to buy water. People who are unable to have clean water have a good chance of dying either from disease or from dehydration. At least 3.4 million people die a year from water problems such as sanitation (One Billion Affected).
