  • Land degradation—a pervasive, systemic phenomenon in all parts of the world—is a major contributor to climate change.  Current degradation of some 12 million hectares per year, notably desertification, “is negatively impacting the well-being of at least 3.2 billion people” and represents “an economic loss of c.10% of global gross product.”
  • Declining land productivity also leads to socio-economic instability.
  • “Unless urgent and concerted action is taken, land degradation will worsen in the face of population growth, unprecedented consumption, and climate change.”
  • A global target of Land Degradation Neutrality will require new policies.  However, reversing current trends “could generate up to $1.4 trillion per year of economic benefits.”
  • The widespread lack of awareness is a major barrier to corrective actions.
