The efforts to conserve parks and protected areas around the world are being aided by Earth observations from space-based sensors operated by NASA and other space agencies as well as commercial providers.
The book released recently highlights how the view from space is being used to protect some of the world's most interesting, changing, and threatened places, NASA said.
"Sanctuary: Exploring the World's Protected Areas from Space," published by the Institute for Global Environmental Strategies (Arlington, Virginia) with support from NASA, debuted at the 2014 World Parks Congress in Sydney, Australia.
"NASA and numerous other space agency partners from around the globe have used this view from space to make incredible scientific advances in our understanding of how our planet works," NASA Administrator Charles Bolden wrote in the book's foreword.
"As a result, we can now better gauge the impact of human activity on our environment and measure how and why our atmosphere, oceans, and land are changing," wrote Bolden.
There are about 209,000 protected areas worldwide, covering 14 per cent of the planet's land and 11 per cent of coastal areas, as well as 3.6 per cent of the world's oceans.
Protected areas featured in "Sanctuary" include Hawaii's Papaphanaumokuakea Marine National Monument, New Zealand's Mount Egmont National Park, the weaving waterways of the Sundarbans in Bangladesh, and the Great Barrier Reef in Australia.
