5. Proposed REDD+ implementation
REDD+ implementation activity
Reducing emissions through deforestation efforts. This activity is suitable for production and protection forests, continue facing the threat of deforestation..
Reducing emissions through forest degradation efforts. This activity is appropriate for all 3 types of forest, which continues to face the same risk of other degraded causes.
Forest Conservation. This is suitable for all types of forests, but especially those areas with primary forest.Bảo tồn rừng.
Sustainable management of forest resources. This is suitable for all types of forests, especially production forest.
Enhancing forest carbon stocks. This is suitable for any kind of forestry land, especially an area degraded or even bare land.
