'afforestational' originates from the word 'afforestation', which is derived from the Latin prefix 'ad-' meaning 'to' and 'forestis' meaning 'forest'.

'afforestation' evolved from the Old French word 'afforrest', which meant 'to turn into a forest', and eventually became the modern English word 'afforestation'.

Initially, it meant 'to turn land into a forest', and this meaning has largely remained the same in modern usage.
