How healthy is your Orinoco River?

Overall the Orinoco River has moderately good health, but there is still room to improve.

At the sub-basin scale, results showed a strong west-east gradient in scores as the Upper Meta had the poorest grade, whereas the Mataven had the highest grade.

The differences between west and east portions of the Orinoco basin are distinguished by development pressure in the west, resulting in poorer water quality, and significant changes to the landscape.
