Innovative Conservation Science to Meet the Challenges of our Time

How to protect the world’s biodiversity will be the point and priority of the 2024 United Nation’s Biodiversity Conference (COP16) October 21 through November 1 in Cali, Colombia. This year’s meeting will focus on the Global Biodiversity Framework developed at the last Biodiversity Conference (COP15) in Montreal, Canada.

COP16: Your Guide to the 2024 UN Biodiversity Conference

October 21-November 1 in Cali, Colombia

Since 2015, governments have had the legally binding Paris Agreement—like a collective guiding star on climate—but now is the time to update decadal globally agreed targets for nature. So the focus is implementing the new, 10-year Global Biodiversity Framework: humanity’s roadmap towards a more nature-positive future.

The science is clear: As global biodiversity continues to decline at an alarming rate, we must protect 30% of terrestrial, inland water and marine areas by 2030. To ensure long-lasting protection, these conserved areas must be effectively managed and inclusively governed.

Biodiversity + Climate Change

Two crises pose a serious threat to life on Earth: the climate change crisis and the nature crisis. They are intrinsically linked. Natural ecosystems play a fundamental role in climate change mitigation, from strengthening the capacity of low-lying areas to withstand storms, to building resilience to drought, floods and fire.

30X30 Protected Areas

TNC supports a new deal for nature calling for 30 percent of ocean, land and water to be managed as intact and fully functional natural ecosystems. It’s not enough to draw lines on a map—we need to improve the design, management, financing and interconnectivity of these critical areas that sustain us all.

Coconut Palms Dominate Over Half of Pacific Atoll Forests

First study of its kind shows that decades of coconut palm agriculture have led to deforestation on over 80 percent of Pacific atolls, and coconut palms now cover more than half of the atolls’ forested areas.

Biodiversity + Protected Areas

Protections should be placed in areas scientifically identified as having the highest conservation value and that represent the planet’s biodiversity. But protected areas alone are not enough without science-based management. A protected area that has lost most of its large mammals, birds and trees through illegal activities cannot fully contribute to reducing extinction rates.

Biodiversity + Indigenous Knowledge

Scientific evidence shows us that indigenous peoples and local communities are often more effective conservation stewards than government-funded protected area agencies. Indigenous owned and managed lands and waters should receive recognition and support for their role in achieving biodiversity conservation targets.

Biodiversity + Siting

Very little of the planet is truly “untouched”—95 percent of the Earth’s surface outside of the polar regions has been modified by humans. Whether it’s clearing land to grow crops and build cities, or fragmenting habitats with highways and railroads, human development has changed the surface of the planet in a variety of ways.

Biodiversity + Cities

Science to help plan cities with nature in mind. With nearly 70 percent of the world’s population expected to live in urban areas by 2050, cities are swelling to accommodate newcomers. It is and will be necessary to integrate biodiversity protection into development, but a new deal for nature should establish national incentives for nature-based solutions in urban areas.
