Like a broken cell phone that can only text or take pictures, but not make a single call, more than 75 percent of the Earth’s land areas have lost some or most of their functions, undermining the well-being of the 3.2 billion people that rely on them to produce food crops, provide clean water, control flooding and more.
These once-productive lands have either become deserts, are polluted, or have been deforested and converted for unsustainable agricultural production. This is a major contributor to increased conflict and mass human migration, and left unchecked, could force as many as 700 million to migrate by 2050, according to the world’s first comprehensive evidence-based assessment of land degradation, released today in Medellín, Colombia.
