Afforestation, restoration and conservation outside protected areas
Planting and restoration, and conservation outside notified parks: the national afforestation schemes and green credits, trees outside forests, community and other conserved areas, corridors, and the nature of cities. Prelims has asked about the aim of the Green India Mission.

Other Effective Area-based Conservation Measures
An OECM is the name for land that lies outside the formal protected area network and still conserves biodiversity in situ over the long term, which is how conservation is counted once it stops at no boundary.
- in situ
- Conservation of a species in its natural habitat, rather than in a zoo, gene bank or botanical garden.
- An OECM counts whoever owns the land, which is what separates it from a notified protected area.
- OECMs count towards Target 3 of the Kunming-Montreal Global Biodiversity Framework, adopted under the Convention on Biological Diversity (CBD), which is the 30x30 pledge.

National Conservation Estate
A column in August argued that India should stop counting only its notified parks and hold one estate instead, in which corridors and community land count towards the pledge as well.
- 30x30
- The Kunming-Montreal commitment to conserve at least 30 per cent of land and 30 per cent of oceans by 2030.
Protected areas
- National parks and sanctuaries already notified by the State
OECMs
- Community forests, wetlands and other biodiversity rich land outside parks
- Recognised under the Convention on Biological Diversity
Ecological corridors
- Strips of habitat that let animals move between protected areas
- Wildlife overpasses on the Delhi-Dehradun Economic Corridor and mitigation in the Pench-Seoni landscape were offered as proof that infrastructure and connectivity can coexist.

The Green India Mission
The Mission was written to improve the forest that already stands as much as to add new cover, and the auditor measured it against both.
- CAMPA
- The Compensatory Afforestation Fund Management and Planning Authority (CAMPA), set up under the Compensatory Afforestation Fund Act, 2016, which holds and releases the money paid by users of diverted forest land for afforestation elsewhere.
92%shortfall against the target for improving forest quality
98%shortfall against the target for added forest cover
- It targets 1.4 million hectares of improved forest quality, and as much again in added cover.
- It runs on public money and is meant to converge with CAMPA and the rural employment scheme.
- The Comptroller and Auditor General (CAG) audited it in 16 States and Union Territories from 2015-16 to 2024-25 and found it far behind its own targets.
- Forest quality improved over 0.11 million hectares and forest cover rose over 0.03 million hectares in that decade.
- Weak convergence with CAMPA and the rural employment scheme, thin funding and poor monitoring are blamed.

The Green Credit Programme
The other way of paying for planting is to price it: land restored to a set standard earns a credit, and the credit discharges somebody's obligation to plant.
- Compensatory afforestation
- The planting required elsewhere when forest land is diverted to a non-forest use, paid for by whoever takes the land.
- Canopy density
- The share of ground covered by tree crowns seen from above, which is how forest is graded as open, moderately dense or very dense.
- The programme was notified under the Environment (Protection) Act, 1986 on 12 October 2023, and is run by the Indian Council of Forestry Research and Education (ICFRE).
- Its plantation method was notified on 22 February 2024 and revised on 29 August 2025.
- State forest departments register the degraded parcels restored, and that registry and the credits earned on it sit on a public dashboard.
- A credit follows five years of restoration and a canopy density of at least 40 per cent, the line at which forest stops counting as open and counts as moderately dense.
- A credit is usable once, against compensatory afforestation, a statutory plantation requirement or a corporate social responsibility (CSR) obligation.

Master Plan for Delhi 2047
Delhi's plan to 2047 treats the Yamuna, the Ridge and the city's heritage as infrastructure the capital has to maintain, each with a programme of its own. That is a change of category: nature stops being the land left over and becomes something the city is obliged to keep working.
Yamuna
- Restore the floodplain
- Treat drains through constructed wetlands and bioremediation
Ridge
- Restore with native species
Heritage
- Cultural Resource Management Plans
- Adaptive reuse
- Transferable Development Rights
- The Master Plan for Delhi is the city's statutory land use plan, prepared by the Delhi Development Authority (DDA).
- A green-blue network plans a city's rivers, drains, wetlands, forests and parks as one connected system rather than as separate parcels of land.
- The Delhi Ridge is an extension of the Aravalli range, among the world's oldest fold mountains.

The Delhi Ridge and the Najafgarh drain
Neha Sinha's Wild Capital: Discovering Nature in Delhi reads the same city from the other end, through its plants rather than its plan. The review takes up the imported tree that took the Ridge, the river that was turned into a drain, and the species that hold on to bare rock.
- Xerophytic
- Adapted to survive with very little water, as the plants of deserts and dry scrub are.
Invasive species
- Vilayati kikar (Prosopis juliflora), introduced from the Americas
- Spreads fast and suppresses native plants
Seed dispersal
- Endozoochory: animals eat fruit and pass the seeds in their droppings
- Many native seeds germinate only after passing through an animal's gut, though soaking in water can work instead
Plant adaptations
- Thorns lack stomata and collect dew, a xerophytic adaptation
- Chasmophytes grow in cracks of rock and pavements
- Bio-crusts of lichens and mosses begin soil formation in primary succession
- The Najafgarh drain is the channelled course of the Sahibi river, which rises in the Aravalli hills of Rajasthan and joins the Yamuna in Delhi.
- A city this dry is mostly scrub country, so its native plants are xerophytic ones built to lose as little water as they can.
- Restoration at the Aravalli Biodiversity Park began by matching native plants to baking sun, desert winds or the shelter of rocks.

- Transferable Development Rights
- Building rights earned by not developing one's own land, usable or saleable elsewhere.
- Bioremediation
- The use of microorganisms or plants to break down or remove pollutants from water or soil.
- Primary succession
- Life colonising bare ground such as rock or sand, where no soil exists, and slowly building soil for later communities.

India's open natural ecosystems, its grasslands, savannas, scrub, ravines and deserts, are still recorded in many places as wastelands, and lose out in land use decisions accordingly.
