Giving Compass' Take:
- Researchers are concerned that the conservation ’30×30′ narrative—30% of the protection of nature by 2030—is not enough to reverse biodiversity and land depletion that has already happened.
- How can donors help increase conservation goals and ambition in climate action?

To meet international goals for maintaining food, clean water, and air, 50% of Earth’s non-Antarctic land surface must remain vegetated, research shows.
April Reside of the University of Queensland’s School of Agriculture and Food Sciences says that losing much more loss of Earth’s native environments may prove disastrous.
“Late last year, a new Global Biodiversity Framework was agreed upon at the United Nations COP15, which includes among its targets the protection of 30% of land and 30% of seas.
“However, our work shows these ambitions need to be set much higher if essential ecosystem functions and services such as soil health, clean air, and water, and more, are to be maintained.
“We cannot set our ceiling at looking after only 30% of the planet—instead, we need to maintain natural ecosystems over much larger areas.
“This ’30×30′ narrative—30% of the protection of nature by 2030—simply won’t be enough to ensure our survival. We need to think more broadly, to halt and, where possible, reverse the depletion of natural ecosystems.”
Reside says changes in the way the biosphere is managed and exploited can make the 50% vegetation target a reality.
The team identified and set out explicit goals for soil conservation, water quality regulation, climate regulation, and biodiversity conservation from existing international agreements.
They then used existing models and global datasets describing soil erosion rates, carbon storage, important biodiversity areas, and wetland and riparian areas, identifying what total area of the terrestrial land surface was required to achieve these goals.
Professor Martine Maron says that this level of conservation was ambitious, but could be achieved in a variety of ways beyond simply establishing more formal protected areas.
“Creating more and better protected areas is great, but we must also create strong policy on deforestation, integrate nature with productive land uses, and support sustainable land uses that don’t deplete natural capital,” Maron says.
“Such management can and should co-occur—and be driven by—people who live in and rely on places where natural and sustainably managed vegetation remains in place.
