The Bonn Challenge is a global initiative aimed at restoring degraded and deforested lands around the world. Launched in 2011 by Germany and the International Union for Conservation of Nature (IUCN), the challenge set a goal of restoring 150 million hectares of land by 2020 and 350 million hectares by 2030. As of 2013, over 20 million hectares of land had been pledged for restoration by countries such as Brazil, Costa Rica, El Salvador, Rwanda, and the United States.

 

Restoration efforts have already been successful in countries such as South Korea, Costa Rica, Pakistan, China, Rwanda, and Brazil. The IUCN estimates that fulfilling the goals of the Bonn Challenge would generate approximately $84 billion per year in net benefits, which could positively affect income opportunities for rural communities.

 

The Bonn Challenge aims to address a variety of issues, including economic security, water security, food security, and climate change. Landscape restoration will contribute to international commitments to reduce climate change by sequestering 1 billion metric tons of carbon dioxide, which will reduce the current emission gap by 20%.

 

One of the most significant commitments to the Bonn Challenge was made by Pakistan's Khyber Pakhtunkhwa province. The 'Billion Tree Tsunami' initiative is a significant step in this direction, and it was the first sub-national pledge to be fully implemented and increased.

 

In addition, the African Forest Landscape Restoration Initiative is also part of the Bonn Challenge. This initiative aims to restore 100 million hectares of land by 2030, with 28 African countries having made a total commitment of 113 million hectares. Ethiopia has made the largest single commitment, pledging to restore 1 million hectares of land. In 2019, the Ethiopian Prime Minister Abiy Ahmed announced the country's goal of planting 4 billion trees in that year alone.

 

In conclusion, the Bonn Challenge is an essential global initiative that aims to restore degraded and deforested lands around the world. Achieving the challenge's goals would generate significant economic, social, and environmental benefits, helping to address issues such as climate change, water security, and food security. Successful restoration programs in countries such as South Korea, Costa Rica, Pakistan, China, Rwanda, and Brazil demonstrate the potential of the initiative.
