Afforestation
Establishing forests on lands that have not been forested for a long period, typically 50 years or more.
What is Afforestation?
Afforestation is the process of planting new forests on lands that have historically not contained forests, or that have been without forests for a very long period (e.g., typically defined as 50 years or more). It involves active tree planting and management to establish a forest ecosystem where one did not previously exist.
Why is Afforestation important?
Afforestation is a vital nature-based solution for carbon removal, as growing trees absorb CO₂ from the atmosphere through photosynthesis. It also offers numerous co-benefits, including biodiversity conservation, soil health improvement, water quality regulation, and local community benefits. It's a key strategy for climate change mitigation.

Frequently asked questions
Afforestation involves planting trees on land that has not been forested for a long time, while reforestation involves replanting trees on land that was previously forested but has been recently cleared (e.g., due to logging or wildfires).
Beyond carbon removal, afforestation can enhance biodiversity, prevent soil erosion, improve water quality, support local economies, and provide recreational opportunities.
Challenges include land availability, ensuring appropriate species selection for local conditions, securing long-term maintenance, managing risks like fires and diseases, and ensuring community engagement and benefit-sharing.
