1- OVERVIEW:
As we know that water is very essential for our lives. With the increasing population the demand of natural water becoming high as it is used for commercial, residential and industrial purposes and water resources becoming less day by day. Global warming and climate change is one of the main reasons of reducing the rainfall and we don’t know how badly it will affect our rainfall system in near future.
In this section I will discuss the Sydney metropolitan water system and current situation of Sydney water system and its security towards supply and comparison to the old system.
• Background:
In 2004, plan was developed to increase the water supply through dams instead of water recycling. In 2006, focused were on the recycling water
In conclusion, this work has evaluated several solutions of the water shortage in China: water usage efficiency improvement, adopting the local agencies on controlling water resources and reasonable water pricing. It has been revealed that all of proposed solutions might be effective, but they should be properly applied and, probably, their combining can contribute to the combating the water scarcity in China. However, some of other solutions should have been evaluated, such as water recycling, and this work might become a base for further studies.
... upon solution to water access disagreements, social and political powers must be willing to compromise since the risks associated with disagreements regarding water allocation may be too great. As stated by Shiyyab (2004), “If sustained over a period of time, these problems will directly affect social harmony, domestic stability and eventually, regional peace.” (p. 30). Investments must be made by industry as well as local and national governments for purification of wastewater so that clean water, when needed, will be available. The necessity of obtaining water is a fundamental human right and,
Although water is all around, very little is drinkable. Six billion people live on earth and 1.1 billion in 31 countries are unable to access safe, clean drinking water. California has only 20 years of water supply left. Ironically, even the wettest place on earth, Cherrapunji, India, has often water shortages. After years of millions of people dying of thirst and disease, a corporate movement to find a solution to the water crisis has now swept the world. Water, a fleeting resource vital to every life, every single day of the year, is now being taken out of the governments control and becoming a commodity bought and sold by big business, a.k.a privatization.
Water shortage in arid and semi-arid regions and declining its availability to a crisis ...
Water is a quintessential element of all life on Earth. Of all the water on Earth, about three percent is fresh and can be used immediately for human consumption. Perth’s climate is drying, yet Western Australia is still consuming relatively high amounts of water. This problem of high consumption of water in a drying climate is far from straightforward There are many elements contributing to water consumption in Western Australia. Broadly, these factors fall under the three pillars of sustainability: social, economic and environmental. Each of these pillars are made up of many components, and all those components are intricately and numerously linked. The whole is greater than the sum of its parts. Using Systems Analysis to examine the interlinked factors of water consumption in Perth and Western Australia is a good way to uncover hidden root causes of the issue of water consumption in WA and start to apply leverage in the most serviceable places.
Perth has two seawater desalination plants, one is completed in 2006 with a 123,000 m3/d (45 GL/yr) water production powered by a wind farm. The other one is almost double size of first one, which is 100 GL/yr powered by 65 MWe of dedicated renewable energy, which together provide half the city’s needs.
Today, water usage is very high. One of the main reasons has been due to an increase in population. Human population is today on the rise. According to the CIA (2015), the birth rate of the human population stands at 1.86%. In the last 100 years, there has been tremendous growth in human population due to advances in medical technology as well as improvement in agriculture. This has led to an increase in water use over the years. In addition, the increase in industries over this period has also led to an increase in water use. Today, there are numerous industries that have come up, each requiring huge amounts of water to run smoothly. The increase in water usage today is partially responsible for the global water crisis. The huge demand for water means that there is less water available for each person and each industry.
Flooding is an extreme climatic event that generates devastation and economic losses all around the world. The extreme climatic events are increasing more severe and frequent due to the climate change. The climate change is a global scale, the mean annual surface temperature has increased over the past century by 0.6°C (IPCC, 2007).Climate models and theoretical arguments further indicate that extreme precipitation events will continue to increase with rises in greenhouse gas (GHG) concentrations (Min et al., 2011). Climate change will have significant impacts on precipitation patterns, overall increase in annual average temperature, increase precipitation of frequency, magnitude, precipitation amounts, severe events and flooding risk. The frequency, magnitude and severity of flooding are also increasing in many parts of the world associated with climate change, population pressure and urbanization (Hirabayashi et al., 2013., Jongman et al., 2014). These increases in the frequency and severity of extreme precipitation, impact of climate change associated damages and losses from flooding, is also likely to increase in the 21st century and beyond (Allamano et al., 2009; Pallet al., 2011).
Water purification and a wastewater treatment plants would be necessary in order to provide the citizens and visitors with clean healthy water. To prevent flooding, this city was built on flood plains.
Many scientific studies also show increases in the intensity, duration, and extent of droughts, higher atmospheric temperatures, warmer sea surface temperatures, changes in precipitation patterns, and diminishing glaciers and snowpack. The bottom line is that causes of climate change, such as greenhouse gas emissions, will have to be minimized if people want to do as much as possible to solve the water crisis.

Water scarcity is harmful to human life because when water is poorly managed throughout the world, those who need water are deprived of nutrients they truly need, causing them to die. This eventually affects the global population. Therefore, many experts have proposed several solutions such as the LifeSaver Bottle, TrojanUVPhox treatment system, and Waste Water Recycling. 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.
Many of these in later years shall need to be addressed as tension rises: Saving and consumption of water Improving drinking water supply Increasing access to clean water supply Decreasing tension between war-ing nation over resources With the population expected to rise 40-50% within the next 50 years, the demand for water in Agricultural needs and Environmental needs will rise as well, creating a more desperate water crisis. Developed countries struggle with managing water consumption. Our high demand in agriculture, industry, and domestic use further complicates this issue. With increasing urbanization and extravagant changes in lifestyle, our use and wasting of water will only increase.
However, in developing countries like India, the agricultural sector is heavily dependent on the south-west monsoons. In view of the rising temperatures worldwide due to global warming and changes in weather patterns associated with it, dependence on rains is not always a possible solution. Failure to properly rain can cripple the agricultural sector, which can lead to an overall rise in poverty. Thus, efficient methods of irrigation need to be developed.... ...
Rainwater harvesting provides an independent water supply during regional water restrictions and in developed countries is often used to supplement the main supply. In times of harsh weather such as droughts and floods, it provides a fresh supply of clean water as well as in cases of mitigate flooding occurring...
Global warming is one of the main causes, which leads to the lack of water and drought. A drought-like condition exists in most of India’s part. Government of India states that 68% of the country is disposed to the drought, which (consequences are) leads to massive migration of people to more favorable places, famine, conflicts among inhabitants. India is known in the world as one of the biggest producers of water-intensive crops such as rice, sugarcane and wheat. According to a survey done by Grail Research, approximately 82% of total water is used for agricultural consumption and 90% of it is employed for irrigation of rice, wheat and sugarcane (Grail Research, LLC, 2009). There are several solutions which could lead to the decr...
