CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

Conservation and restoration of coastal ecosystems, including tidal salt marshes, seagrass meadows and mangrove forests (collectively called blue carbon (BC) ecosystems), offer excellent opportunities around nature-based solutions for climate mitigation and adaptation. The purpose of this three-day workshop is to provide decision makers with information on: (i) how to use and implement the IPCC 2013 Wetlands Supplement, (ii) how mangroves fit into the national Forest Reference Emission Level (FREL) and Nationally Determined Contributions (NDCs); (iii) the importance of the Transparency, Accuracy, Comparability, Completeness, Consistency (TACCC) principles of the UNFCCC; and (iv) how to improve estimates of uncertainty for the FREL through advanced techniques such as Monte Carlo simulations.

Goal and objectives
The overall goal of the workshop is to build the capacity of officials of the Philippines Government in developing higher tier and more accurate emission factors (EFs) for mangroves, incorporating those EFs into the upcoming FREL and NDCs, and participating in REDD+ and other C credit payment mechanisms. The workshop is designed to allow direct interaction and two-way communication with Philippines Government officials with the following specific objectives:

  1. To familiarize participants with the IPCC 2013 Wetlands Supplement through hands-on sessions on the use and understanding of the Wetlands Supplement for mangroves by navigating through Chapter 4 (Coastal wetlands) of the Supplement, and to provide scientific background for some key EFs (e.g. deforestation) for a better understanding on how to develop Tier 2 EFs.
  2. To present the Transparency, Accuracy, Comparability, Completeness, Consistency (TACCC) principles of the UNFCCC.
  3. To introduce methods for estimating uncertainty into activity data and emission factors for reports such as those on the FREL (e.g. Monte Carlo simulations).

The program is designed to allow exchange of knowledge and experience among participants and facilitators/resource persons in the following areas:

  • Methods: The use of IPCC Wetlands Supplement, especially the chapter on coastal wetlands
  • Methods: Introduction to uncertainty analysis (Monte Carlo)
  • Data: Identification of data availability and gaps through TACCC diagnostic
  • Methods: How to incorporate mangroves into the FREL and NDCs

Expected outputs

  • Participants will familiarize themselves with the IPCC 2013 Supplement on Wetlands.
  • Participants are aware of the gaps in data and information (missing sources and sinks) and practice with quality control and quality assurance (QA/QC) exercises to improve the FREL.
  • Participants are well-equipped with methods and analytical capacity to further develop improved FREL and updated NDCs.
