The Bonn Challenge is a global effort to restore 150 million hectares of the world’s deforested and degraded land by 2020 and 350 million hectares by 2030. It is an implementation vehicle for national priorities such as water and food security and rural development while contributing to the achievement of international climate change, biodiversity and land degradation commitments.

The 2020 target was launched at a high-level event in Bonn in 2011 and was later endorsed and extended to 2030 by the New York Declaration on Forests of the 2014 UN Climate Summit.

Underlying the Bonn Challenge is the forest landscape restoration approach, which aims to restore ecological integrity at the same time as improving human well-being through multifunctional landscapes.

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