A global aspiration

The Bonn Challenge is a global aspiration to restore 150 million hectares of the world’s deforested and degraded lands by 2020 and 350 million hectares by 2030.  It was launched by world leaders at a ministerial roundtable in Bonn, Germany, in September 2011.  Underlying the Bonn Challenge is the forest landscape restoration approach, which aims to restore ecological integrity at the same time as improving human wellbeing through multi-functional landscapes.

The Bonn Challenge is not a new global commitment but rather a practical means of realizing many existing international commitments, including the CBD Aichi Target 15, the UNFCCC REDD+ goal, and the Rio+20 land degradation neutral goal.
