The Rio Grande/Rio Bravo is an ecological treasure, winding 1,800 miles through the Southern Great Plains and
the Chihuahuan Desert, the largest desert in North America. An essential river to communities in the
American Southwest and Northern Mexico, the Rio Grande/Rio Bravo provides fresh water to nearly 16 million
people across both countries, including over 20 Tribal Nations and Pueblos. The Rio Grande is also rich in
biodiversity. It is the lifeblood of the Chihuahuan Desert ecoregion, which is home to more mammals than
Yellowstone National Park and more birds than the Everglades National Park. And 50% of all fish species in
the river are found nowhere else in the world.
The Rio Grande/Rio Bravo is one of the world’s most at-risk rivers suffering from water scarcity due to the
human-caused climate crisis, water management, infrastructure, and increasing water use. Without urgent
interventions, the river may cease to support the millions of people and wildlife who rely on it and impact
its ability to support production of the commodities that many of us enjoy.
