Background

At its 43rd Session (Nairobi, Kenya, 11 – 13 April 2016), the IPCC Panel decided to prepare a special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems.

Experts met on 13 – 17 February 2017 in Dublin, Ireland to prepare a draft outline for the report.

At its 45th Session (Guadalajara, Mexico, 28 – 31 March 2017), the Panel approved the outline for Climate Change and Land: an IPCC special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems.

The Special Report was developed under the joint scientific leadership of Working Groups I, II, III in cooperation with the Task Force on National Greenhouse Gas Inventories, and supported by the Working Group III Technical Support Unit.

Authors and Review Editors

107 experts from 52 countries were selected as Coordinating Lead Authors and Lead Authors – who are working on  each individual chapter – and Review Editors, who ensured that comments by experts and governments were given appropriate consideration as the report developed.

40% of the Coordinating Lead Authors are women.  53% of the authors are from developing countries, making this the first IPCC report to have more authors from developing countries than from developed countries.  The full list of Coordinating Lead Authors, Lead Authors and Review Editors is here.

A call for nomination of authors was sent to governments, observer organizations and IPCC Bureau Members on 5 April 2017. Graphics that provide background information about the nominees are available here

Lead Author Meetings

 

Pre-Scoping

The Steering Committee for the Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems circulated a questionnaire to IPCC Focal Points and Observer Organizations ahead of the Scoping Meeting in February 2017 to get input on the structure and contents of the report. You can download the questionnaire and stakeholder consultation report here.

Scoping

A scoping meeting for the Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems was held on 13 – 17 February 2017 in Dublin, Ireland. The meeting resulted in a draft scoping paper describing the objectives and an annotated outline of the Special Report as well as the process and timeline for its preparation.

All the details of the scoping meeting are available in the scoping meeting report.
