Bad news for wildlife: 2.3 million square miles of protected areas around the world face human pressure from activities like road building, urbanization, or grazing, according to a new study. Lead author Kendall Jones, a PhD candidate at the University of Queensland, said in a statement, “We found major road infrastructure such as highways, industrial agriculture, and even entire cities occurring inside the boundaries of places supposed to be set aside for nature conservation.”
Millions of square miles “have this level of human influence that is harmful to the species they are trying to protect,” University of Queensland professor James Watson told the BBC. “It is not passive, it’s not agnostic; it is harmful and that is quite shocking.” Scientists at the University of Queensland, University of Northern British Columbia, and Wildlife Conservation Society (WCS) teamed up for the study, described as a reality check, that was recently published in the journal Science.
Watson said that governments claim the areas are protected “when in reality they aren’t.” Even though more land has been protected in the last few decades, the lack of real protection is a major reason for biodiversity‘s continued, catastrophic decline.
There was a ray of hope in the study’s findings: protected areas that have strict biodiversity conservation objectives in place tend to experience less human pressure. WCS listed the Keo Seima Wildlife Sanctuary in Cambodia, the Yasuni Biosphere Reserve in Ecuador, and the Madidi National Park in Bolivia as examples.
Watson said, “We know protected areas work — when well-funded, well-managed and well placed, they are extremely effective in halting the threats that cause biodiversity loss and ensure species return from the brink of extinction. There are also many protected areas that are still in good condition and protect the last strongholds of endangered species worldwide. The challenge is to improve the management of those protected areas that are most valuable for nature conservation to ensure they safeguard it.”
