The Bonn Challenge Barometer of Progress

As of: July 2020

Objective and activities

Forests possess a great variety of species, serve as carbon sinks and fulfil many other functions that must be preserved. The Bonn Challenge is the most important international initiative for forest restoration. The participating states set the goal of restoring around 150 million hectares of forest by 2020. The project uses the “Bonn Challenge” barometer of progress to develop a system to document and publish the progress of the Bonn Challenge, and to inform donors and partners about the implementation status. The barometer is being developed in six pilot countries and implemented all over the world. The methodology is used to measure progress in policy and budget commitments, technical knowledge, implementation on the ground and ‘carbon benefits’. Experiences from the pilot countries are published, and the implementation status of the Bonn Challenge, success stories and reporting are disseminated via high-profile public campaigns.

State of implementation/results

  • The Bonn Challenge Barometer has been developed and is currently operational in 9 countries
  • IUCN released the 2nd Bonn Challenge Progress report in June 2019 presenting and analyzing the data collected over 2018.
  • The Barometer protocol is a flexible yet standardised assessment framework developed by IUCN in partnership with the participating countries Brazil, El Salvador, Mexico, Rwanda, Sri Lanka. The Bonn Challenge Barometer’s protocol (conceptual framework) is now in implementation phase in the six pilot countries. In-depth application of the Barometer in 2018 in six pilot countries and rapid application in an additional 13 countries yielded the following results: Altogether, these 19 countries have collectively pledged a total 97 Mha, representing 57 % of current commitments. From the 13 countries reporting on area under restoration, we now know that 43.7 Mha are under restoration transition. This equates to 29% of the total Bonn Challenge target. For 5 pilot countries participating in this initiative, 89 % of pledged hectares are under restoration. This is a total of 27.34 million hectares out of 30 million hectares pledged. For the five countries with in-depth Barometer application, the management of degraded forest lands through silviculture and natural regeneration, and the improvement of agricultural lands through agroforestry, are the predominating FLR strategies (87 %). – See also here:…
