Reforestation could be defined as the natural or intentional restocking of existing forests that have been depleted, through deforestation activities. Reforestation is effective because a single tree can absorb as much as 22 kilograms of carbon dioxide per year and can sequester 0.91 tonnes of carbon dioxide by the time it reaches 40 years old.This has an impact of reducing climate change and safeguarding natural resources.

The cost of planting tree is low, making reforestation a go-to method for cost effective means of reducing carbon dioxide in the atmosphere and increment of vegetation cover. Reforestation could be done through various methods including, large-scale industrial plantations, the introduction of trees into existing agricultural systems, small-scale plantations, establishment of tree cover on communal lands, and rehabilitation of degraded areas through tree planting or assisted natural regeneration. Required is establishment of reforestation programs and initiatives for counteracting global climate change drivers. Reforestation has also been shown to be useful in the process of nurturing once farmed land back to a condition where it can be used for agriculture or conservation.

Reforestation can also help mitigate the effects of soil degradation and pollution depending on the methods of planting, location, and plant spec
