KK: /riˌæfɔːrɪˈsteɪʃən/
The process of planting trees in an area where there used to be a forest but has been removed or destroyed.
The government launched a new initiative for reafforestation to combat climate change.
Reafforestation → It is formed from "re-" (meaning again) and "afforestare" (from Latin, meaning to establish a forest). The word "reafforestation" means the act of establishing a forest again in an area where it has been depleted or removed.
Think of 'again' ('re-') and 'establishing a forest' ('afforestare') to remember that reafforestation means to create a forest once more.
