Afforestation vs Reforestation
Creating new forest where none existed versus restoring forest on land that was recently forested — different carbon and ecology outcomes.
Start here
Afforestation is establishing forest cover on land that was not forest for a long period (wasteland, scrub, grassland); reforestation is restoring tree cover on land that was recently deforested or degraded forest. Both appear in climate pledges and CAMPA funds, but ecologists treat them differently — afforestation on natural grasslands can harm biodiversity, while reforestation tries to undo recent damage.
UPSC tests definitions under IPCC/UNFCCC land categories (Afforestation vs Reforestation in LULUCF) and Indian schemes like Green India Mission and compensatory afforestation under the Forest (Conservation) Act.
Side-by-side comparison
| Feature | Afforestation | Reforestation |
|---|---|---|
| Legal trigger (India) | Forest (Conservation) Act compensatory afforestation | Working plan / CAMPA for degraded RF |
| Species choice | Often commercial monoculture (eucalyptus, teak) | Prefer native mix in restoration projects |
| Biodiversity outcome | Variable; may simplify ecosystem | Can restore habitat if native structure returns |
| UNFCCC term | Afforestation (A) under LULUCF | Reforestation (R) — both AR projects |
| Criticism in India | Plantations ≠ ecological forests; tribal rights | Quality vs target hectares planted |
| IPCC land category | Afforestation (A) — non-forest to forest land-use change | Reforestation (R) — forestland remaining forest after temporary loss |

Teak plantation on Rajasthan scrub vs restoring Chhattisgarh mine patch
Planting teak on land that was semi-arid scrub for centuries is afforestation — new forest category on non-forest land. After an iron-ore lease ends in Chhattisgarh, mandatory reclamation replants native species on what was forest five years ago — that is reforestation. The first changes land-use category; the second heals a fresh wound.
What this means for the exam
Afforestation = forest where there was no (recent) forest. Reforestation = forest again on recently lost forest land.
Understand the difference
CAMPA and the plantation debate
Compensatory Afforestation Fund (CAMPA) collects levies when forest land is diverted. States spend on plantations — often afforestation on non-forest plots. Critics argue hectare counts hide ecological loss: a 100-year-old moist deciduous forest cannot be “replaced” by a five-year eucalyptus block. True reforestation with native species on degraded forest land is closer to ecological restoration.
India’s forest cover statistics rose partly from plantations on non-forest land (afforestation) while mined and encroached tracts await genuine reforestation. Van Mahotsav tree-planting on school grounds is horticulture — not necessarily either term in the technical IPCC sense.
