Understanding what works in forest-based climate change mitigation
1. Understanding what works in forest-based
climate change mitigation
Amy Duchelle
UNFCCC COP24 Official Side Event – Katowice, Poland
06 December 2018
2. FORESTS AS KEY TO CLIMATE SOLUTION
• Staying below 1.5oC
depends on forest
protection, sustainable
forest management, and
restoration
• What have different forest-
based mitigation actions
achieved so far?
• Rigorous impact evaluation
needed to promote learning
and inform future efforts

6. FOREST & LAND USE OUTCOMES
The few evaluations of local REDD+ initiatives on forest/land use
outcomes show moderately encouraging results
Simonet et al. 2018. Transforming REDD+ Book.
7. SOCIAL & OTHER ENVIRONMENTAL OUTCOMES
• Well-being effects small,
with mixed sign, but more
likely to be positive when
incentive components
included
• Land tenure highlighted as
persistent challenge
• Studies on biodiversity
and adaptation outcomes
scarce

9. TAKE-AWAY MESSAGES
• Need for more reliable evidence on
impacts of forest-based mitigation
• Challenges in evaluating impacts of
real-world policies and programs
(controls, diversity of interventions,
real effects vs. general noise of data,
etc.)
• Call for scientific upgrade in impact
evaluations (“Conservation Impact
Evaluation 2.0”)
