1. Introduction
The Queensland region recently suffered its worst drought in over a century. This period was shared with a rapid increase in the city’s population. A combination of severe drought and a rapid increase in population had a permanent impact on the city’s water management strategy. Brisbane population is expected to reach 4.5 million by 2050.
This report aims to look at how the relationship between Brisbane’s water resources and population growth have effected society, the economy and the environment. It will briefly look at the growth rate of Brisbane’s population how this subsequently affected the city’s ability to meet challenges in water demand. The report will critically analyse the State Government five water management strategies. It will explore whether the strategies are environmentally sustainable in the growing population. It will aim to determine whether the strategies effective in protecting the state’s biophysical resource. The report will critically evaluate the current and potential impacts of water management strategies to the biophysical resource base.
2. Population growth and water supply
The population growth of Brisbane has widely been viewed mark of economic prosperity (Wasimi, 2010). The Australian Labor government national policy encouraged population growth by giving financial incentives for people to have more children and encouraging migration (Lowe, 2010). However, the growth affected the city’s capacity to cope with growing demand for water. Brisbane’s water consumption is divided into ‘direct’ such as household water and ‘indirect’ such as commercial use (Rutherford and Finlayson, 2011). Brisbane’s water consumption growing rapidly due to the urban affluent lifestyle such ...

Australia’s resources otherwise known as factors of production – natural resources, labour, capital and enterprise, are relatively scarce, resulting in the economic problem of relative scarcity as we cannot satisfy all our needs and wants in Australia as they are unlimited. Collective and individual wants are
Water is the most relied upon resource on earth and if it disappeared life could not and would not exist on this planet. So if one of our main sources of water in South Australia, The Murray Darling-Basin, becomes unusable then we would need to find the problem and do everything possible to stop it or counteract it. This report investigates on salinity in the Murray Darling-Basin, using the issue question “Is there enough being done to counteract the effects of salinity in the Murray?” as the focus. Salinity is a key significant environmental challenge which the Murray faces and if left unmanaged it could cause serious implications for water quality, plant growth, biodiversity, land productivity, infrastructure and could lead to a loss of a water source that’s critical to human needs. In this investigation five different aspects of this salinity issue are presented and these aspects include what Salinity is and how it has become an issue, what the effects are, how salinity affects the rest of Australia, what can be done and is anyone doing anything and finally what the visions are for the future of the Murray and its salinity levels.
Metro Atlanta is on a collision course with reality – and the shock of this collision will have profound political and economic implications for future growth throughout the Southeast. The core problem is that Atlanta’s runaway growth will soon outstrip the available water supply (Corps, 1998). And if Atlanta continues to increase its water consumption until the maximum limits are reached, the effects on downstream users will become catastrophic, both economically and environmentally.

The Hoover Dam is a modern marvel and a testament to American ingenuity. At over six million six hundred thousand tons and jetting seven hundred sixty feet from the canyon floor, six hundred sixty feet across the bottom and, one thousand two hundred forty four feet across the top, the structure is awe inspiring even to a modern audience. Three quarters of a century since its completion it still stands as a symbol of one of the greatest construction projects of the ages. The need for a dam to block the Colorado River was not a new idea when construction began in 1931, but had been mulled around since the dawn of the century. Flooding due to runoff from the Rocky Mountains had devastated crops, and a need for hydroelectric power increased the need for a dam. In 1922 Black Valley was chosen as the spot for the dam’s construction. No one construction company was large enough to take on the project alone, so a group of companies formed a joint venture in order to bid the job. The Six Companies Inc. made up of Morrison-Knudson, the J.F. Shea Company of Portland, MacDonald & Kahn Ltd, Pacific Bridge Company of Portland, Henry J. Kaiser, Bechtel Company of San Francisco were awarded the winning bid for the dam at forty eight million eight hundred ninety thousand nine hundred fifty five dollars. The construction management team had a Herculean task in building this behemoth and faced many problems in its construction. A few of the major issues posed to the team were diverting the Colorado River, provisioning the men and material to get the job done, and the actual construction of the Hoover Dam. The heights involved with project led to many safety obstacles that had to be overcame.

Australia has had one of the most outstanding economies of the world in recent years - competitive, open and vibrant. The nation’s high economic performance stems from effective economic management and ongoing structural reform. Australia has a competitive and dynamic private sector and a skilled, flexible workforce. It also has a comprehensive economic policy framework in place. The economy is globally competitive and remains an attractive destination for investment. Australia has a sound, stable and modern institutional structure that provides certainty to businesses. For long time, Australia is a stable democratic country with strong growth, low inflation and low interest rate.(Ning)

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.

Clean and safe drinking water resources are becoming scarce as the population grows. The world is facing many problems, but the most important thing needed to survive, is water. Water is getting low in many countries, therefore residents are suffering the misfortune of not having the reliable source of clean water. Today many countries are having water shortages meaning rivers, lakes, streams and groundwater are not enough to rely on for supplying water demands. For example, California is facing a drastic water shortage, the natural water resources are not enough to fulfill their water demands.
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.
With the population expecting 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.
