One-third of the Earth’s land surface is already degraded. The UN estimates that more than 2.6 billion people are harmed by land degradation, with countries losing up to US$10.6 trillion (£7.8 trillion) a year because of damage to “ecosystem services”, including the benefits people get from nature such as water and food.
Unhealthy soil is a major contributor to land degradation.
