RAISG found that protected areas (1.7 million sq km) and indigenous lands (1.6 million sq km) amount to 45 percent of the Amazon, with another 475,168 sq km of native territories proposed for demarcation. There are some 33.7 million people living in the Amazon, including 385 indigenous tribes and at least 71 “isolated groups” (sometimes called “uncontacted groups”).
The highest ratio of officially protected Amazon lands occurs French Guiana (72.3 percent), Ecuador (72 percent), Venezuela (71.5 percent), and Colombia (64 percent). Guyana is the laggard of the the bunch with just under 20 percent of its Amazon territory under any form of protection.
The map relies on official government data, so areas that may be protected on paper, may not be protected on the ground. Nonetheless, the map is the most comprehensive protected areas pan-Amazon map available.
