Edited for resources


Water is a vital resource for human survival and is essential for agriculture, industry, and ecosystems. Climate change is exacerbating water insecurity by causing changes in precipitation patterns, leading to more extreme weather events such as droughts and floods, and impacting the availability of fresh water. It is projected that by 2025, 1.8 billion people will live in areas with absolute water scarcity and two-thirds of the global population, over 4 billion people, will live with severe water scarcity. In addition, water scarcity is likely to exacerbate in already water-stressed regions, reducing crop yields and increasing the risk of water-related disasters and conflict.

Addressing water insecurity is critical to ensuring food security and sustainable development, and it is essential that we take action to reduce greenhouse gas emissions, work toward shifting our systems and individual actions and adapt to the impacts of climate change on water resources. Below are resources where you can learn more key subsections of this complex matter, also including our coastal and oceanic water, groups working toward solutions and making positive progress as well as things you can do to take action.

Despite the ease of turning on the tap and accessing water in an instant, the journey your water took and its value is important to recognise. Water comes from various sources such as rainwater,  surface water (lakes, rivers, and streams), and groundwater (aquifers). A significant amount of the world’s water is also stored in glaciers and ice caps which are released into rivers and oceans when the ice melts.  Knowing where water comes from is important because it helps us understand water availability, quality and management going into the future considering the impacts of climate change on water resources.


Melbourne Water – The main water supplier in Melbourne, this resource page provides information on Melbourne’s sources of water, how it is treated and delivered, and how to conserve water. The City of Melbourne also provides a comprehensive page on the city’s water supply.


Yarra Valley Water – The Yarra Valley provides the majority of our fresh, high-quality water. This resource explains the water storage dams, supply, and delivery and the page includes an interactive map that shows the location of the water supply system and the different sources of water.


US Geological Survey – This resource aims to give a comprehensive understanding of the Earth’s water resources and their distribution, as well as the challenges and opportunities associated with managing these resources. It also provides information on the different forms of water such as freshwater, saltwater, and brackish water, where they are found on Earth and their relative availability with interactive maps and data.


As aforementioned, life as we know it critically relies on our freshwater supplies. With those supplies being threatened, the way we use and manage water faces compromisation. Information on why this is important and the different ways this nuanced challenge must be considered can be found below.
