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 ...

“Last Call at the Oasis” is a documentary about our world’s water crisis. The film discusses how many large cities in America are getting closer to use up their available water, how many areas across the globe do not have access to drinking water and are forced to drink contaminated water, how water shortages are causing acts of violence and are causing stress to agricultural communities, and a possible solution of using recycle water to stop us from wasting so much water. The film goes around the globe to talk to scientists who are studying contaminated water, people who have become very sick due to this water, and to the agricultural community in Australia where, unfortunately, some farmers have take their own lives due to water shortages.
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 water that supplies Western Australia comes from a variety of sources, including surface water and groundwater. Recent technologies have emerged which allow WA to use water sources that were previously unusable, such as desalinated ocean water and recycled wastewater (Government of Western Australia, 2012). The scale for this report is the state of Western Australia. This scale will allow for analysis of more elements of water consumption in Perth and its surrounding areas, not just the city’s consumption of water, but consumption from other key industries that fuel the economy of Perth and WA, including mining and agriculture.
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.
“Don’t waste that water! Kids in Africa don’t even have water to drink!” Almost every American has heard this saying before. We have heard this because there are water shortages in third world countries like Africa, as seen in the movie “Blue Gold”. But why have we developed this notion that there are only water shortages in third world countries? When in reality, there is a shortage of water right here in our home country. The Colorado River’s water is high in demand as it serves millions of people, powers industries, and is home to all different kinds of wildlife. The Colorado River will not be able to keep up with the increasing demand of water and soon enough the river will go dry. Organizations like the Colorado River Water Users Association are trying to change the way that the water is used and adjust how it is managed. The Colorado River is drying up and the western states are running out of water, however, public policy is trying to regulate and preserve the Colorado River to make it more sustainable in the future.
Decreasing rainfall and exterior reservoir recharge since the mid-1970s in Western Australia have been related to fluctuations in atmospheric circulation that are constant with what would be predictable in an atmosphere subjective by rising greenhouse gas intensities. The Water Corporation of Western Australia is focusing the lessening surface water resource by setting out to distribute a ‘climate-independent’ reserve of water for domestic
The following is a report on Australian drought situation. It will identity the definition of the drought, describe the causes of drought, represent impact of drought in Queensland and introduce management to help farmers cope with future drought occurrences.
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
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.
With Australia’s population rapidly nearing 23.5 million people, the issue of sustainability and the number of people Australia can allow to live comfortably without significant damage to the surrounding environment is extremely important. The misconception that Australia is underpopulated with plenty of room to accommodate the worlds rising population is widespread. With the majority of Australian land being arid and inhospitable, finding available land and resources to accommodate a rising population is placing a huge amount of pressure on the Australian environment. Australia’s population growth consists of two main components; births minus deaths and net migration. While Australia’s birth rate sits at 1.9, lower than the 2.1 needed to replace our aging population, our expanding population comes from overseas migration accounting for around 60 per cent of our growth (Department of Immigration and Border Protection). Currently the total migration rate is set at 210,000 people per year making Australia’s population quickly on the rise. This poses an important discussion regarding the impacts of such a rise and if there is a specific number that constitutes a sustainable Australia regarding population. The issues that may come to pass as a result of overpopulation are great and varied. These include and are not limited to; resource shortages, social conflict, overcrowding, pollution, habitat and biodiversity loss and a lowering in national health standards. The Australian Conservation Foundation (ACF) has put forward arguments opposing a rising population due to the predicted environmental damage we would face as an outcome. A few of the main problems associated with an unconstrained population are outlined in this essay.
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)
Water shortage in United States is a potential problem. Today almost no one consider how serious the issue is. Water is the main resource of our living; we have it and do not realize how much water we waste. In U.S.A. there are over usage of water in irrigation, agriculture, industry and over usage in residential purposes. According to CBS News report (Strassmann, 2010), average American uses about 150 gallons every day, while Englishmen use 40 gallons, Chinese – 22 and Kenyan - 13 gallons. Strassmann also points out that scientists count, that consumption of water is much more than supply, so that in next three years 36 states will faced the problem of water shortage. Nowadays, Las Vegas, Texas, California, Colorado, Nevada have already run into troubles.
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. As of this year, nearly 1.1 billion people live without clean drinking water and 2.6 billion live without adequate water sanitation. The McDonald's down the street, however, will sell you a 1/3 pounder burger for only 150 gallons. Changes in lifestyle can easily reduce this number and help not only save water, but money as well. Currently, with our diminishing water supply, one of the main goals of humanitarian organizations is ensuring that everyone has t...
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.
