Grand Challenges for Engineering in the 21st Century

Want to know what to do with your life. A diverse committee of experts from around the world, at the request of the U.S. National Science Foundation, identified 14 challenges that, if met, would improve how we live.

Here is their list in no particular order. You can learn more about each challenge by clicking on it.

You can vote for which is most important

The committee decided not to rank the challenges. NAE is offering the public an opportunity to vote on which one they think is most important and to provide comments at the Engineering Challenges website


That seems to be the conclusion of a report from the National Oceanic and Atmospheric Administration that finds the northern Gulf of Mexico is sinking much faster than previously thought.

Every year, the Mississippi and other rivers dump millions of tons of sediment into the Gulf. All that weight pushes down on the Earth, causing some shoreline areas to disappear entirely, and other to sink dangerously low. Low-lying areas are vulnerable to flooding, especially during hurricane season.

Planners need to know how high or low each area is, in order to make the proper precautions. But a recent re-measuring showed that Louisiana is sinking faster than expected. Hurricane preparations currently underway may not be enough to protect some areas.
