Forests are essential in our lives and are among the planet's most important carbon sinks. Besides providing habitats for wildlife, they filter the air, stabilise and protect soils, store water, and contribute to the balance of our climate. However, global forest areas have declined sharply in recent decades due to increasing settlements, agriculture, illegal logging, and raw material extraction. Afforestation, reforestation, and revegetation activities significantly increase a forest’s carbon storage capacity in both the biomass of the forest and in the soil. The storage capacity varies according to the tree species, age, and location. Experts distinguish these activities in the following way:

Afforestation converts non-forested areas into forest ones. Reforestation restores forest areas that have been damaged or deforested in the past. Revegetation increases the vegetation through planting trees, shrubs, or other plants.
