Carte du projet Half-Earth

Si nous voulons sauver les espèces de l'extinction, nous avons besoin d'un atlas complet qui cartographie la biodiversité de la Terre et qui soit accessible à tous. Ce n'est qu'à cette condition que nous pourrons prendre des décisions complexes sur la meilleure façon de préserver la nature pour toutes les formes de vie.

The E.O. Wilson Biodiversity Foundation’s objective is to map the location and distribution of the planet’s species at a high enough resolution to allow for on-the-ground decisions to be made at a local level. Together with our partners, we have developed the Half-Earth Project Map, a high-resolution, dynamic world map and decision-support tool that guides where place-based species conservation activities are needed the most to protect Earth’s species, including our own.

The map visualizes a global assessment of biodiversity richness and rarity at a 1–50 km scale for all terrestrial and marine vertebrates and at 1km to country scale for hundreds of thousands of invertebrate and plant species. No other open-access tool contains this resolution of global species data.

“The Half-Earth Project map is becoming a powerful tool for discovery as it combines the best of our mapping technology and global biodiversity data to help us chart a new path forward for the planet.”

Designed for a wide variety of users, the map is easy to read and navigate and can be accessed by anyone in any community. Coupled with data showing human pressures, irrecoverable carbon, and existing protected areas, the map reveals priority areas for conservation.

The Species Protection Index (SPI) measures the amount and location of currently protected land in a country and the number and location of species found both inside and outside of these protected areas. SPI ranges from 0–100, with 100 reflecting a country practicing good stewardship and promoting equitable conservation efforts within its borders. SPI is an important Essential Biodiversity Variable, an indicator for success that can be used to determine how a country is doing in any given area regarding global biodiversity stewardship and identify where additional attention is needed.

Les fiches de rapport nationales résument les efforts de conservation d'un pays. Ils peuvent être utilisés pour explorer les progrès, les besoins et les défis en matière de conservation propres à chaque pays et peuvent aider à prioriser le soutien et les ressources en conséquence.

The Half-Earth Project Map is led by the E.O. Wilson Biodiversity Foundation in collaboration with Vizzuality, Map of Life, and Esri, with funding support from Esri, the Gordon and Betty Moore Foundation, the Burt’s Bees Foundation, and Jeff and Laurie Ubben.
