As 3,000 delegates trudged through thick Davos snow to meetings and parties, one thing they were not short of was water. But that did not stop the Hollywood A-lister Matt Damon taking centre stage to launch a campaign to combat water scarcity.
It is an issue that is threatening developing economies around the world in a way that risks spilling over to the rest of the world. Water scarcity has been a regular feature in the World Economic Forum's list of top threats for the past seven years.
Damon is trying to change this through water.org, the company established by the star in 2009 with Gary White, an engineer and entrepreneur. It uses private money to do public good, helping some of the 663 million people who do not have access to clean water.
Research by the World Bank shows "water stress" could knock up to 6 percentage points off growth in some regions by 2050. This was likely to cause "extreme societal stress" in regions such as the Middle East and, in extreme scenarios, trigger mass migration as families relocate to find water and survive.
In short, a lack of clean water is a "risk multiplier" that is contributing to the issues shaping the world today, including the continuing refugee crisis. Dominic Waughray, a member of the WEF's executive committee, says unless industry takes action to tackle this issue, the damage to the global economy could be much greater.
