Governments must protect quarter of world's land to avert environmental crisis

New analysis argues for protection of 25% of planet's land and 15% of oceans by 2020

Washington, DC – World leaders gathering in Japan next week at the UN's biodiversity summit must agree to put at least 25 percent of the Earth's land and 15 percent of the oceans under protection by 2020 if they are to be successful in their efforts to solve the current global environmental crisis, a new analysis by Conservation International showed today.

Putting a larger area of the planet under protection is crucial to secure important biodiversity and the delivery of vital services from nature to people. Natural habitats – and the species and genetic resources they harbor – support the global economy and billions of people who directly depend on them for immediate needs, like food, income and shelter. Currently, about 13 percent of the world's terrestrial areas and less than 1 percent of the open oceans are protected.

The analysis shows that at least 17 percent of the Earth's land is necessary to protect priority areas for known biodiversity and an additional 6-11 percent is needed to ensure adequate storage of carbon in natural ecosystems. The analysis clarifies that protected areas are not just strict nature reserves, but can also refer to areas managed for multiple uses, such as recreation, sustainable economic activities or for their unique beauty and cultural value.

When world leaders meet at the Convention on Biological Diversity (CBD), which starts next Monday in Nagoya, they will discuss a set of 20 targets to slow biodiversity loss over the coming decade – one of them being about the need to put areas under protection. The numbers being discussed are around 15-20 percent for land and a yet to be determined percentage for oceans.

"The current targets are clearly inadequate in protecting biodiversity and ensuring key services to people. Science shows us that we need more places to be protected and where the key places are," said Conservation International's Frank Larsen, lead author of the analysis. "There is also evidence that the costs of expanding protected areas are compensated by the many benefits, including new jobs and people's ability to withstand the effects of climate change."

Lina Barrera, Conservation International's Director of Biodiversity and Ecosystem Services Policy, added: "The problem is that most of the costs are local, while most of the benefits are global, so politicians do not see much incentive to make things happen. This is the time to be brave and get real about the need to put us on the path for a more sustainable future."

According to the analysis, protecting 25 percent of the lands and 15 percent of the oceans is still a preliminary and conservative estimate. It takes into account the needs to address only carbon storage, but when other important ecosystem services – like water supply, crop pollination and fisheries – are added, the numbers will be higher. Also, in regions highly impacted by environmental degradation, protected areas are likely to be the only intact natural environments that will remain.
