Planting of new forests or trees in areas or lands where there historically have not been any forests. Governments and non-governmental organizations (NGOs) directly engage in programs of afforestation to create forests that can help increase carbon capture and sequestration (see CCS), and improve biodiversity. According to some definitions afforestation can also mean planting forests on lands that have not contained forests for a long time, which distinguishes it from reforestation. (see also Reforestation)
