Ever since a global mitigation mechanism that aims to reduce emissions by avoiding deforestation and forest degradation (REDD+) was introduced in climate change negotiations, governance challenges in implementing this concept in tropical forest countries have received considerable attention. In particular, multilevel governance has been identified as a key challenge, as REDD+ aims to tackle local deforestation activities through a global results-based financial scheme.
