Narrated by Anne Thompson of NBC News, the four-part video series draws on fundamental scientific research conducted to improve the way we use water efficiently and effectively. Viewers will learn how the vital aspects of human life – water, food, and energy – are reliant upon each other.

“A sustainable water supply is essential for a variety of interconnected human needs, from drinking water to electricity,” said Barry Johnson, NSF acting assistant director for engineering, which co-funded the videos with NSF’s Geosciences Directorate. “To meet our water needs in the future will require research and new water technologies for purification, smart agriculture, energy-positive water treatment and more.”

Viewers can learn more about the series and join the discussion by using the hashtag #HumanWaterCycle on Twitter.

Human Water Cycle: Water, Food and Energy

Scientists and engineers, including Greg Characklis at the University of North Carolina at Chapel Hill, are studying the connections between water, food and energy in the human water cycle to develop new, sustainable ways of meeting our water needs


Human Water Cycle: Drinking Water

Safe, clean drinking water is a fundamental human need. Orlando Coronell at the University of North Carolina at Chapel Hill is developing improved membrane technology to purify drinking water more effectively and efficiently.


Human Water Cycle: Agriculture

Soil salinization prevents crops from taking up water and nutrients due to an excess of salt in the soil. Meagan Mauter at Carnegie Mellon University is developing technology to monitor salinity levels to allow farmers to make better watering decisions.


Human Water Cycle: Wastewater

Wastewater is what gets flushed down the toilet, rinsed down the drain, and produced by places such as factories, workplaces, and homes. Kartik Chandran at Columbia University is changing the perception of wastewater by treating it more efficiently and creating energy from resources found in it.

About the National Science Foundation

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2010, its budget is about $6.9 billion. NSF funds reach all 50 states through grants to nearly 2,000 universities and institutions. Each year, NSF receives over 45,000 competitive requests for funding, and makes over 11,500 new funding awards. NSF also awards over $400 million in professional and service contracts yearly.
