Why are we running out of fresh water?
The problem of water scarcity is worsening as a result of climate change and population growth. In our new whitepaper, we dive into water scarcity, and how technology could help alleviate the problem.
As every schoolchild knows, water covers approximately 70% of Earth’s surface. Yet around half of the world’s population currently experiences severe water scarcity for at least part of the year,1 and around two billion people currently don’t have access to safe drinking water.2
As the graphic below shows, this is because despite most of the planet being covered in water, just 3% of this is fresh water, which is needed for people, animals and crops. Two-thirds of that scarce fresh water is locked up in glaciers or is otherwise unavailable for use.3
Compounding the problem, much of our accessible fresh water has become polluted. Climate change is also accelerating the frequency of extreme weather events.
Together, these factors have put intense pressure on our fresh water resources.
Pressure on the planet’s supply of clean water, exacerbated by a growing population and rising industry use, is drawing increasing public and political focus.
Along with hundreds of pledges and commitments, governments are driving investment in clean water. The European Investment Bank commits €3 billion to water infrastructure investment annually,4 and the US Bipartisan Infrastructure Law has launched a €50 billion water infrastructure plan.5
The water tech market is projected to grow by 32% from 2022 to 2028, with the majority of total expenditure by technology concentrated in fluid-handling equipment such as pipes, pumps and valves.6
