Water shortage is a global problem and the consequences of water deficit can be a future crisis. According to Hasan Ali (2002, 1-3) the world large water deficient region is the Middle East. Jordan is one of the water-scarce countries in this area, Jordan is similarly in the top of ten water-deficient countries. The reasons of this problem are the features of nature such as semi-arid climate, few water sources and low precipitation. Because of that, the country has the lowest per head basis of water in the world. The other reasons are social effects namely rising population, resulting from a high degree of urbanization, gain of engineering systems and economic development (Akawwic et al. 2009, 197-198). The aim of this essay is to suggest the most effective solutions to avoid the future crisis in Jordan. Four solutions will be analysed in this essay: firstly, adoption of irrigation systems; secondly, water harvesting; thirdly, desalination; fourthly, water management. Initially, the largest customer of water resources is the agriculture sector. It is a really danger for Jordan because the statistics show that water consumption of agriculture is about 80 % of all water. Therefore, firstly, the suitable solution is to reduce water consumption of agriculture (Akawwic et al 2010, 201). It could be realized with using effective irrigation methods such as drip or micro irrigation (ibid.,202). The irrigation methods, in particular, “furrow and basin irrigation”, which were often used in past, required large quantities of water. Therefore, these approaches were substituted by micro irrigation, in order to economize water resources (Abbasi et al 2010, 337). Generally, micro irrigation is the favourable and effective method, but there is in...

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.
Desalination plants overall could be a huge benefit to society for its high quality of water and intuitive water treatment techniques, however the big environmental impacts and high costs to produce water at a desalination plant makes it unfavorable to most communities especially the poorer communities. Although costs for the production and upkeep for a desalination plant has been going down while the technology of it rises, the only true benefit for having a desalination plant would only come into affect when it is near a body of ocean, such as Tampa Bay Water. All in all desalination plants could soon be the face of future water treatment plants and water sources, but for the present time it is still only a niche water source.
Archaeological excavations on ancient agricultural sites reveal that there was little homogeneity in irrigation system building structure and style. In other words, most irrigation systems found were unique to the particular conditions farmers faced in the area. Ancient farmers likely built according to their individual circumstances, that is to say building structure, style, and size would have depended on proximity to geological surface runoff and/or active floodplains. This characteristic of Negev desert farming suggests “the agriculture systems were built in a wide variety of forms highly compatible with the local conditions by local farmers and not by a well-designed external governmental effort”. In short, farming methods in the region were unique to the local conditions and resources available to individual cultivators without the interference of a centralized system. The dissimilarities between different agricultural sites speak to the wide range of temperature and rainfall discrepancies between the northern and southern parts of the Negev desert. Unique agricultural set-ups allude to the necessity for ancient farmers to cultivate according to their individual needs based on location, rainfall, and access to floodplains.
Presently, in the USA the California state is starting suffer with water crises. Therefore, the state started planning many desalination plants. There are three current desalination station, and the government is planning more fifteen. Figure 9 shows the desalinations plants in the California state. There are many critics about the desalinization plants.20 Arguments use against the plants are which use huge amounts of energy, and is very danger for the marine life.20 Desalinated water construction costs approximately $2,000 an acre foot.20 In addition, to produce one gallon of drinking water need two gallons of seawater.20 This process consumes about 38 megawatts to remove 100 million gallons of seawater per day.20

Water was essential to all people of ancient civilizations. It was something they would depend on year in and year out. This was a big development because people learned how to use their surroundings (water) to their advantage. The reason that farming grew is because of the fertile soil. Rivers were the biggest part in how early people lived. Further into the paper I will explain the agriculture, water source, and the transportation within the Nile River, the Huang He (Yellow) River, and the Indus River.
An environmental policy refers to the commitment of an organization to the laws, regulations, and other policy mechanisms concerning environmental issues and sustainability. These environmental issues can pertain to anything from air and water pollution to deforestation and solid waste management. Today, we live in a world full of developing countries that face environmental issues and degradation every day. Yemen, known to be one of the least developed countries, is facing various environmental issues, as well as social and political challenges while on its way to development and becoming a much more stable country.
Above, is a quote from a man recovered from an article of writing back in the ancient Egyptian times. Irrigation is a form of re-routing water, to parts of land that the water is needed, in farming terms. For Example, there are two crops, one crop is getting all the water, and it’s flooding. With irrigation, the farmer will re-route the water towards the other crop, as well as sharing the water with the crop that was being flooded. So now, both crops are getting enough water and they are not flooding nor suffering from drought.
The average human can not live any longer than three days without water. Many of the world’s fresh water sources are running dry or are being contaminated, particularly in developing nations, leaving many without safe water to drink. Only two and a half percent of the Earth’s water is freshwater, and less than one percent is accessible by humans (not tied up in ice caps). This one percent of the Earth’s water supply is expected to sustain a population of over 7 billion people, each needing 2.6 liters a day to remain fully healthy, plus all of the water required for agriculture and industry. These scenarios will only become more and more prevalent as time moves on and we consume more water. The United Nations has classified our planet as being in the midst of a global “water crisis.” Global water supply and shortages are becoming an incredibly real and serious issue, and planning for the future is key to preventing population decline due to a lack of safe drinking water. Shortages of drinking water lead to wars and serious international conflict for basic human survival needs. One of the most popularly and commonly proposed solutions to this problem is to create seawater desalination plants to remove salt from ocean water to make it safe to drink. These water desalination plants, however, are not a viable option to carry us in to the future due to their potentially harmful impacts and expenses.
Water Issues in South Asia If there is any single most important issue that mars bilateral relations among the countries of the subcontinent, it is water. The issues of cross-border water distribution, utilisation, management and mega irrigation/hydro-electric power projects affecting the upper and lower riparian countries are gradually taking centre-stage in defining interstate relations as water scarcity increases and both drought and floods make life too often miserable. Thanks to its location, size and contiguous borders with other South Asian countries, it is India, in its capacity as both upper and lower riparian, that has come into conflict with most of its neighbours, except Bhutan, on the cross-border water issues. Given an atmosphere of mistrust, an upper riparian India has serious issues to resolve with lower riparian Pakistan and Bangladesh and, despite being lower riparian, with the upper riparian Nepal.

Sandra Postel, on the other hand, has a different opinion than Danielle’s. She proposed that “without increasing water productivity in irrigation, major food-producing regions will not have enough water to sustain crop production”.
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. The epidemic of neglecting the eminence of water in Lebanon is best illustrated when it comes to water pollution, lack of water conservation methods, and unjust beach dredging. On the other hand, this significant issue could be resolved by the collaborative efforts of the Lebanese society and authority.
