GFOI R&D and GOFC-GOLD Land Cover Science Meeting
2nd Expert workshop on lessons learned from Accuracy Assessments in the context of REDD+


Oslo, Norway

26-28 June, 2017


Organized by:

The GFOI R&D Coordination component, the GOFC-GOLD Land Cover Office , and the Norwegian Space Center (NSC)


The background information on the meeting can be found in the announcement.

Workshop objectives

The objective is to actively work on providing improved guidance on accuracy assessments in the context of REDD+. In particular, the workshop provided guidance to practitioners to meet the IPCC good practice criteria related to bias and uncertainty in estimates of activity data. More specifically we aim to:

  1. Discuss and present country examples and case studies for accuracy assessments.
  2. Draw lessons learned and synthesize them into good practice for accuracy assessments.
  3. Discuss how understanding of uncertainties can feed back into efforts for continuous improvements.
  4. Scope a new MGD module capturing the new guidance
  5. Discuss additional related and follow-up issues for GFOI R&D synthesis (i.e. EFs) and contributions to 2019 methodological refinement of the IPCC GPG

Agenda and outcomes

Day 1: Monday 26 June



Henrik Fliflet

Background and objectives

Martin Herold

Summary of first workshop on this topic: What has been agreed? What requires further discussion at this workshop?

Andres Espejo

Lunch break


Presentation of case studies and experiences:

  • What are good practices for countries to assess the uncertainty of accuracy for area estimates /activity data?
  • What are the lessons learned from your country examples?
  • How methodological advancements and new data can improve estimation (i.e. from Sentinels) and how should that effect the AA procedures?

Andres Espejo, Kay Kallweit, Evan Notmann, Christoph Sannier

Day 2: Tuesday 27 June


Further discussions on case studies and experiences:

  • What type of guidance can be provided with respect to operational methods/examples?
  • What issues remain open issue and require further discussions to develop solutions?
  • What issues cannot be solved because we lack basic R&D?

Erik Naesset, Ronald McRoberts , Stephen Stehman

Lunch break


Further discussions on case studies and experiences continued

Pontus Olofsson

New guidance plans Working groups on synthesizing and developing new guidance:

  • What new points need to be included in the guidance?
  • Is any current guidance obsolete?

Carly Green Discussion facilitated by Maria Sanchez

Workshop dinner

Day 3: Wednesday 28 June


SEPAL demonstration

Erik Lindquist

Working group discussions and presentations on scoping of new MGD module:

  • What guidance is needed for the MGD?
  • How can we formulate this?
  • What new modules are required?

Ronald McRoberts on sampling design Discussion facilitated by Carly Green

Lunch break


Next steps:

  • Addressing additional issues which need further (i.e. uncertainties of trends?)
  • Next expert workshops on uncertainties related to EFs and biomass estimates

Discussion facilitated by Martin Herold
