Moderate
Moderate
SE England drier than parts of Mediterranean. Leaky pipes waste ~20% of supply.
🇳🇴 Norway
Entire nation
Low
Very low
Among most water-secure nations on Earth. No credible shortage projection under any climate model.
Water zero projections

When natural freshwater
systems fail

Estimated year at which natural freshwater supply can no longer meet drinking water demand without emergency-scale intervention. Assumes business-as-usual trajectories and no major policy change.

"For much of the world, 'normal' is gone."

⚠ All estimates assume no major policy change, infrastructure investment, or desalination scale-up. "Water zero" = drinking water systems fail at scale, not every drop gone. Subnational regions (cities, aquifer zones) collapse before national figures.

What you can do

Actionable steps
at every scale

The science is settled, the question is what we do with it. Here are concrete actions (personal, community, political, and systemic) that compound when millions of people take them.

Individual

Start in your own home

  • Install low-flow showerheads and faucet aerators, reduces household water use 25–50% with no lifestyle change
  • Fix leaks immediately. A single dripping faucet wastes 3,000+ gallons per year.
  • Reduce or eliminate meat consumption, especially beef. Animal agriculture uses 70% of global freshwater and beef production requires ~1,800 gallons per pound. A plant-based diet reduces your water footprint by up to 55%.
  • Shift diet toward lower water-intensity plant foods. Lentils, beans, and vegetables require 90% less water than animal proteins.
  • Collect rainwater where legal for lawn and garden use. Many municipalities provide free barrels.
  • Run dishwashers and washing machines on full loads only; use cold water settings where possible.
  • Know where your water comes from, your local utility watershed report is public record.
Community

Build local resilience

  • Advocate for greywater recycling systems in your municipality, treated household water can be reused for irrigation and toilets.
  • Support local Indigenous water rights and knowledge. Indigenous-led watershed stewardship is among the most effective in the world.
  • Push your school board or employer to install water refill stations and eliminate single-use plastic bottles.
  • Organize or join community water audits, many local governments fund them.
  • Plant native, drought-adapted species in shared green spaces to reduce irrigation load.
  • Support local farmers practising regenerative agriculture, which rebuilds soil water retention.
Political

Demand better governance

  • In Canada: demand the federal government update the 1987 water policy. Write to your MP directly. It's 38 years out of date.
  • In the US: pressure representatives to renegotiate the Colorado River Compact, which allocates water based on 1920s data that no longer reflects reality.
  • Oppose development projects that don't include water impact assessments.
  • Support candidates with explicit, costed water infrastructure plans, not vague "clean water" pledges.
  • Advocate for water pricing reform that makes large industrial and agricultural users pay true market rates while protecting low-income household access.
  • Demand transparent public water accounting, where does your city's water go, and who has rights to it?
Systemic

Push for structural change

  • Support international water aid organizations working in Pakistan, India, and sub-Saharan Africa where crisis is already acute.
  • Oppose virtual water exports, countries exporting water-intensive crops from water-stressed regions are effectively exporting their water.
  • Push for wetland protection legislation. Wetlands are the Earth's water filters and flood buffers, we've lost 35% in 50 years.
  • Support investment in water-efficient agricultural technology, drip irrigation, crop switching, soil health, over continued aquifer mining.
  • Back forest protection. Forests are watersheds. Amazon deforestation is dismantling South America's rainfall system.
  • Treat water as infrastructure, not commodity. Oppose privatization of municipal water systems.
