IntroductionWater is a quintessential element of all life on Earth. Of all the water on Earth, about 3% is fresh and can be immediately used for human consumption. Perth's climate is drying, but Western Australia continues to consume relatively large amounts of water. The problem of high water consumption in a dry climate is far from simple. There are many elements that contribute to water consumption in Western Australia. In general, these factors fall into the three pillars of sustainability: social, economic and environmental. Each of these pillars is made up of many components, and all of these components are connected in complex and numerous ways. The whole is greater than the sum of its parts. Using systems analysis to examine the interconnected drivers of water consumption in Perth and Western Australia is a good way to uncover the hidden root causes of WA's water consumption problem and start leveraging where it helps. Context of water consumption in Western Australia the water that supplies Western Australia comes from a variety of sources, including surface water and groundwater. Recent technologies have emerged that allow Western Australia to utilize previously unusable water sources, 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 enable the analysis of more elements of water consumption in Perth and surrounding areas, not just the city's water consumption, but also the consumption of other key sectors that fuel the Perth and WA economy, including the mining and agriculture. the supply comes from the Gnangara underground water system, which, depending on weather conditions, consumes more water by watering the gardens more than necessary. Additionally, families must have money to purchase irrigation systems and water their gardens. If these attitudes do not change within the household, how can we expect a change in water consumption outside the household in businesses? CONCLUSION - 300There are good reasons to be concerned about water sustainability in Western Australia. Water is connected to all spheres of sustainability: environmental, social and economic. Using systems analysis to explore the reasons why water consumption is the way it is in WA, three key factors emerged: an arid climate, well-being in WA and community awareness and education. These three factors are intertwined and influence each other. While water consumption in Western Australia can be… I'll finish this later.
