The Next Edge

To feed, employ, and sustain the world, our oceans must first be in good health. It is becoming increasingly clear that humans have a substantial impact on these marine ecosystems, and that these impacts are not just threatening the high-seas, but also the humans that depend on them for their livelihoods and well-being.

The health of our oceans is, therefore, primarily a human concern. But how do we measure the health of something as vast and bewildering as an entire ocean?

For many years, scientists have struggled to find a way to make the concept of ocean health meaningful and measureable. There have been a few breakthroughs but no real solution to allow us to concretely measure if things are getting better or worse and by how much? That is, until now.

Published in last week’s issue of the journal Nature The Ocean Health Index is a groundbreaking tool that allows us to take a look at how we as humans benefit from the big blue. The Index examines social, economic, and ecological factors, scaling both globally and locally to give us an accurate assessment. It finally gives us the baseline we need to measure progress...

Comparing different parts of the world's oceans, the index weighs whether the human activity there is sustainable or in need of better management.
