Supplementary Information:

This file contains detailed information on all of the individual components that were used to construct the global road map, and explains how the individual data layers were integrated.  The individual data layers are provided below.

Individual components of the Environmental-values Map

  • Supplementary Figure 1. Number of threatened terrestrial vertebrate species (birds, mammals, amphibians) that are listed as Threatened, Endangered, or Critically Endangered.
  • Supplementary Figure 2. Estimated number of plant species per ecoregion globally, adjusted for ecoregion area (no. species 10,000-km-2).
  • Supplementary Figure 3. Integrated biodiversity layer, incorporating data on threatened vertebrates and plant diversity.
  • Supplementary Figure 4. The geographic distribution of 35 biodiversity hotspots globally.
  • Supplementary Figure 5. Distribution of important Bird Areas and Endemic Bird Areas globally.
  • Supplementary Fig. 6. Distribution of Global 200 terrestrial ecoregions across Earth’s land surface.
  • Supplementary Figure 7. Merged layer showing the combined distribution of High-biodiversity Wilderness Areas and Frontier Forests.
  • Supplementary Figure 8. Composite map of key habitats and wilderness globally.
  • Supplementary Figure 9. Estimated carbon-stock losses (Mg C ha-1) from conversion of vegetation to agriculture.
  • Supplementary Figure 10. Magnitude of climate-regulation services (0-1 index of temperature and moisture regulation) from natural terrestrial vegetation.
  • Supplementary Figure 11. Composite map of carbon storage and climate-regulation services provided by terrestrial vegetation.

Individual components of the Road-benefits Map

  • Supplementary Figure 12. Estimated increases in calorie production per harvested hectare (kcal ha-1) from yield gap closure, for four major crops globally.
  • Supplementary Figure 13. Proportion of each 1-km2 pixel converted to farmland or grazing globally.
  • Supplementary Figure 14. Travel time (minutes) to nearest sizeable city (>50,000 residents) globally.
  • Supplementary Figure 15. Projected national-level increases in agricultural production (%) from 2000 to 2050.
  • Supplementary Figure 16. An empirically derived index of agro-ecological suitability based on local soil fertility and climatic conditions.
