Thirst

Water covers 71% of our planet. Yet billions of people face a future where turning on a tap is no longer guaranteed.

This is the story of how abundance became scarcity — and what we can still do about it.

The Scarcity Gap

Since 1960, global freshwater resources per person have halved as population doubled.

Rivers that once ran year-round now dry up before reaching the sea. Aquifers that took millennia to fill are being drained in decades.

Note: The bar chart shows renewable freshwater per capita in cubic metres. The Middle East & North Africa region is now below the 500 m³/year "absolute scarcity" threshold.

A World of Stress

By 2025, two-thirds of the world's population may live in water-stressed conditions.

Water stress occurs when demand exceeds available supply. Climate change is accelerating the shift from occasional drought to chronic scarcity.

Hot zones: Northern China, India, the Middle East, and the southwestern United States are experiencing the fastest rates of groundwater depletion.

The Human Cost

Water scarcity is not an abstract statistic. It shapes daily life, health, and survival.

People without safe water 0 2 billion
Deaths per year from water-related disease 0 829,000
Hours spent collecting water (women/girls daily) 0 200 million
Global crop production at risk by 2050 0 25%

When water runs short, food prices rise, economies stall, and conflict over resources becomes more likely. The World Bank estimates that water scarcity could reduce GDP growth in some regions by up to 6%.

Pathways Forward

The crisis is severe, but solvable. The technologies and policies that work already exist.

  • Drip irrigation can cut agricultural water use by 40% while increasing yields.
  • Water recycling in cities can reduce freshwater demand by up to 50%.
  • Desalination is now cheaper than ever; Israel gets 80% of its drinking water from the sea.
  • Well-managed watersheds and wetland restoration improve both supply and quality.
  • Water pricing reforms reduce waste and fund infrastructure where it is needed most.

What remains is the political will and investment to scale what already works.
