 Looking at water resources is important because Australia is the driest continent which 70% of that is arid or semi arid. In addition to its water scarcity, it also has the lowest percentage of the rainfall as runoff, so ensuring sustainable use of Australia's scarce water resources is critical. Climate change is affecting agriculture, sea level rise, wildfire and causing extreme weather. But actually all of them are happening through changing in the water storage. So each of them is a water storage then. Nowadays, satellites, hundreds of kilometers up there in this space, are providing us with the different components of the water storage, such as soil moisture, rainfall, and even deep groundwater aquifers. Using satellite data not only gives a continental estimation of water scarcity over the continent, but also can ensure the accuracy of sub-millimeter for water storage estimation. A water budget can be easily estimated by the satellites as they are able to observe and measure how much water is entering to the country and how much water is existing in the land. So such information helps us to estimate available water over a region. If we can estimate water budget over an area for a long time, we may be able to predict it for the future as well. So we are saving lives because we are saving water.
