Human pressure destroying world's protected land

IANS  |  Sydney 

One-third of the world's protected land is in a state unlikely to conserve endangered thanks to intense human pressure, says an international study that offers a shocking reality check on efforts to avert a crisis.

The greatest damaging impacts of human activities on protected land is found in heavily populated places including Asia, and Africa, said the study published in the journal Science.

"We found major such as highways, industrial agriculture, and even entire cities occurring inside the boundaries of places supposed to be set aside for nature conservation," said from the University of in Australia.

"More than 90 per cent of protected areas, such as national parks and nature reserves, showed some signs of damaging human activities," Jones added.

For the study, the researchers used the most comprehensive global map of human pressure on the environment, the Human Footprint, to analyse human activity across almost 50,000 protected areas.

The results showed that six million square kilometres of protected land -- equivalent to two-thirds the size of -- is in a state unlikely to conserve endangered

Large, strictly protected areas were under far less human pressure than smaller protected areas where wider ranges of human activities were permitted, the findings showed.

The study clearly showed nations were overestimating the space available for nature inside protected areas, said James Watson, at the University of

"Governments are claiming these places are protected for the sake of nature when in reality they aren't," Watson said.

"It is a major reason why biodiversity is still in catastrophic decline, despite more and more land being protected over the past few decades," Watson added.
