SCIENTISTS PREPARE BLUEPRINT FOR BIODIVERSITY LOSS REVERSAL

RESEARCH SHOWS HOW NATURAL LANDS CAN BE PROTECTED AND LINKED TOGETHER TO SUPPORT A GLOBAL RECOVERY THAT BENEFITS BOTH BIODIVERSITY AND HUMAN WELFARE 

A group of scientists and experts produced the first comprehensive global-scale analysis of terrestrial areas essential for biodiversity and climate resilience, totaling 50.4% of the Earth’s land. The report was published in Science Advances entitled “A ‘Global Safety Net’ to reverse biodiversity loss and stabilize the Earth’s climate,” and highlights the importance of protecting and restoring the natural world to address three converging crises – climate change, the loss of biodiversity, and the emergence of novel viruses such as COVID-19. 

The research team was led by the research organization RESOLVE in collaboration with the University of Minnesota, Arizona State University, Globaïa, and others with support from One Earth. The data compiled for the Global Safety Net (GSN1) is available through an interactive web application developed by One Earth in partnership with Google Earth Engine. Users can click on a country, state, or eco-region to see configurations of biologically important land for each region. 

The two-year research effort builds upon multiple global-scale data sets to identify areas that require conservation beyond the 15.1% of land area currently protected. These are compiled into five main layers at a 1 km resolution: Species Rarity Sites, High Biodiversity Areas, Large Mammal Landscapes, Intact Wilderness, and Climate Stabilization Areas. 

The report concludes that an additional 35.3% of land is needed to conserve sites of particular importance for biodiversity and ecosystem services. Fifty eco-regions and twenty countries contribute disproportionately to the total. One immediate priority identified is the protection of 2.3% of land area, which provides critical habitat for the world’s most endangered species. 

The paper presents for the first time a “common but differentiated” approach for area-based targets under the United Nations Convention on Biological Diversity, which will be held next year in Kunming, China. Each of the world’s 846 eco-regions has a unique combination of layers, offering recommended area-based conservation targets for each country. 

The analysis includes estimates of carbon storage by layer, making the same map relevant for government commitments under the Paris Climate Agreement (UNFCCC). It also highlights the vital role of indigenous lands in protecting biodiversity and reversing climate change, which cover 37% of the Global Safety Net area.

A complementary global-scale connectivity analysis was performed by the research organization Globaïa, demonstrating that a relatively modest land area – approximately 350 million hectares – could connect isolated fragments of nature together, increasing the resilience of ecosystems and our biosphere as a whole.
