Bonn Challenge

The Bonn Challenge is a global goal to bring 150 million hectares of degraded and deforested landscapes into restoration by 2020 and 350 million hectares by 2030. Launched by the Government of Germany and IUCN in 2011, the Challenge surpassed the 150-million-hectare milestone for pledges in 2017.

We respond to the urgent issue of land degradation affecting over 3 billion people and over 30 per cent of Earth’s arable land. We do this by working with countries, organisations and private entities to pledge and achieve ambitious targets to restore degraded and deforested lands.

We align our work with the Sustainable Development Goals (SDGs), the Aichi Biodiversity Targets, the Land Degradation Neutrality (LDN) goal, and the Paris Climate Change Agreement – all together providing a roadmap for a sustainable planet. u2028

To achieve these goals, we rely on a flexible, nuanced approach to restoration called forest landscape restoration (FLR). FLR restores ecological integrity while enhancing human well-being.
