A vast lowland region in South America spanning parts of Argentina, Paraguay, and Bolivia, known for its grasslands and savannas.
From Quechua 'chacu' or Spanish 'chaco' meaning hunting ground or field. The term refers to the Great Chaco, one of South America's largest wilderness areas.
The Chaco is one of the world's least explored and least populated regions despite being larger than France—it remains a frontier where indigenous peoples maintain traditional lifestyles while the rest of the world races forward.
