Use afforestation carefully as a means to sequester carbon, restore degraded ecosystems, foster biodiversity, and support vulnerable communities.
Afforestation involves the deliberate introduction of trees to areas that have never or not recently had trees in order to create a forest. Planting trees has become popular in recent years. The practice has the potential to sequester a significant amount of carbon, given that a single tree can absorb one tonne of carbon in its lifetime. Some afforestation projects plan to grow one trillion trees. Afforestation has diverse benefits, including the creation of living barriers that stave off desertification, protecting land from flooding, and generating income from sustainable forest products. However, afforestation must be done carefully. It should only be attempted where it is ecologically appropriate, the new trees harmonize with native flora and fauna, and the risk of monocultures is minimized. Projects must be equitable and involve the participation of the Indigenous peoples and local communities who call the land home.
