In the last few decades, the global change in land use has been driven primarily by agricultural activities. This rapid expansion and intensification has affected converted ecosystems, and poses a threat to biodiversity, the planet’s climate system and its hydrological cycles. Currently, we are using about 12% of the world’s land surface for crop production. The proposed planetary boundary is to exceed no more than 15%, coupled with a global program that:

  • uses the most productive land for agriculture
  • preserves forests and ecosystems with high environmental and biodiversity values
  • maintains soil carbon and ecosystems in healthy conditions

The remaining 3% ‘allowance’ refers to abandoned cropland in Europe, North America, and North Asia and some areas of Africa’s savannas and South America’s tropical ecoregion.
