Forest Policy and Legislation

3.1 National Forest Policy, 1988

The National Forest Policy, 1988 replaced the colonial-era Forest Policy of 1952. Its principal aim is to ensure environmental stability and ecological balance.

Key objectives:

  • Maintain environmental stability and restore ecological balance
  • Conserve natural heritage and protect biological diversity
  • Increase forest and tree cover to one-third of the total land area (two-thirds in hills and mountains)
  • Meet the requirements of rural and tribal populations for fuelwood, fodder, minor forest produce, and small timber
  • Create a massive people's movement, with involvement of women, for achieving conservation goals
  • Increase the productivity of forests to meet essential national needs

Key principles:

  • No forest land should be diverted to non-forest purposes without prior approval
  • Rights of tribals and forest dwellers to be protected
  • Forests should not be worked for revenue generation alone -- conservation must take priority

3.2 Forest Conservation Act, 1980

The Forest (Conservation) Act, 1980 was enacted to check indiscriminate diversion of forest land to non-forest uses. It requires prior approval of the Central Government for:

  • Dereservation of reserved forests
  • Use of forest land for non-forest purposes
  • Assignment of forest land by way of lease to any private person or entity

3.3 Forest (Conservation) Amendment Act, 2023

The Forest (Conservation) Amendment Act, 2023 (Act No. 15 of 2023) introduced significant changes:

Feature Detail
Renamed Act renamed to Van (Sanrakshan Evam Samvardhan) Adhiniyam, 1980
Preamble Added Statutory recognition to India's commitment to Net Zero Emission by 2070, NDC targets by 2030, and increasing forest cover to one-third of land area
Applicability Clarified Covers land declared as forest under Indian Forest Act, 1927 or any other law, and land recorded as forest in government records on or after 25 October 1980
Exemptions Land diverted to non-forest use before 12 December 1996; strategic projects within 100 km of international borders/LAC/LoC; up to 10 ha for security infrastructure; up to 5 ha in LWE-affected districts for public utility
New Permitted Activities Infrastructure for frontline forest staff, ecotourism facilities, zoo and safari within forests

Gram Sabha Empowered to initiate, verify, and approve claims -- central authority in the process
Protection No eviction or removal of forest dwellers until recognition and verification of rights is complete

Social Forestry and Joint Forest Management (JFM)

4.1 Social Forestry

Social forestry involves the management and protection of forests and afforestation on barren lands, with the purpose of meeting the needs of the community. It includes:

  • Farm Forestry -- growing trees on private agricultural land
  • Community Forestry -- raising trees on community lands (village commons, roadsides, canal banks)
  • Extension Forestry -- planting trees in areas beyond conventional forests (wastelands, degraded lands)
  • Agro-forestry -- integrating trees with agricultural crops and livestock on the same land

4.2 Van Mahotsav

Van Mahotsav is an annual tree planting festival observed across India during the first week of July, started in 1950 by K.M. Munshi, the then Union Minister for Food and Agriculture. It aims to generate public awareness about afforestation and environmental conservation.

4.3 Joint Forest Management (JFM)

JFM is a participatory approach that involves local communities and the forest department in forest protection and management. It was initiated following the 1988 National Forest Policy and formalised through a Government of India circular in 1990.

Key features:

  • Formation of Village Forest Committees (VFCs) or Forest Protection Committees (FPCs) at the village level
  • Communities share responsibilities of forest protection and receive a share of forest produce in return
  • Covers degraded forest areas -- community participation helps in regeneration
  • Over 1.18 lakh JFM committees operate across India, covering roughly 23 million hectares

4.4 CAMPA -- Compensatory Afforestation Fund

The Compensatory Afforestation Fund Act, 2016 (CAF Act) establishes a non-lapsable fund at the national and state levels to compensate for loss of forest land diverted to non-forest use.

Feature Detail
Fund Distribution 90% to State CAMPA; 10% to National CAMPA
Accumulated Corpus Approximately Rs. 95,000 crore at the time of the Act's enactment
Utilisation Compensatory afforestation, assisted natural regeneration, enrichment of biodiversity, wildlife habitat improvement, forest fire control, soil and water conservation
Operational Since Rules notified 10 August 2018; Act came into effect 30 September 2018

Mangroves in India

Mangroves are salt-tolerant trees and shrubs found in tropical and subtropical tidal regions. They provide critical ecosystem services including coastal protection, carbon sequestration, fish breeding habitat, and biodiversity support.

5.1 Mangrove Cover (ISFR 2023)

India's total mangrove cover is 4,992 sq km, constituting 0.15% of the country's geographical area.

5.2 Distribution

Region Share of India's Mangrove Cover Key Features
West Bengal (Sundarbans) ~42.45% Largest contiguous mangrove forest in the world; UNESCO World Heritage Site; home to Royal Bengal Tiger
Gujarat ~23.66% Spread across Gulf of Kutch, Gulf of Khambhat, and southern coast; cover increased by 253 sq km between 2001--2023
Andaman & Nicobar Islands ~12.39% Diverse mangrove species along sheltered coasts and creek systems
Odisha (Bhitarkanika) Significant Second largest mangrove ecosystem in India; Bhitarkanika hosts saltwater crocodiles
Andhra Pradesh Significant Krishna-Godavari delta mangroves
Maharashtra Moderate Mumbai's mangroves declared as reserved forests

These three regions (West Bengal, Gujarat, A&N Islands) together account for roughly 78% of India's total mangrove cover.

5.3 Ecosystem Services

  • Coastal Protection -- act as natural buffers against cyclones, storm surges, and tsunamis
  • Carbon Sequestration -- mangroves are among the most carbon-rich ecosystems (blue carbon)
  • Fish Nurseries -- provide breeding and nursery grounds for fish, shrimp, and crabs
  • Biodiversity -- support a wide variety of birds, reptiles, mammals, and aquatic organisms
  • Livelihood Support -- sustain fishing communities and support honey collection, timber, and fuelwood

5.4 Threats to Mangroves

  • Conversion to aquaculture ponds and agricultural land
  • Coastal industrial development and port expansion
  • Pollution from upstream industries and urban centres
  • Rising sea levels and increased salinity due to climate change
  • Cyclone damage, especially in the Bay of Bengal coast

5.5 MISHTI Scheme

The Mangrove Initiative for Shoreline Habitats & Tangible Incomes (MISHTI) was announced in the Union Budget 2023-24 to promote mangrove plantation along India's coastline through convergence of MGNREGS, CAMPA, and other sources.


Coral Reefs in India

Coral reefs are underwater structures formed by calcium carbonate secreted by corals (tiny marine animals called polyps). They are among the most biodiverse ecosystems on Earth.

6.1 Types of Coral Reefs

Type Description
Fringing Reef Grows directly from the shore; separated by a narrow, shallow lagoon; most common type globally
Barrier Reef Separated from the coastline by a deep, wide lagoon; runs parallel to the coast
Atoll A ring-shaped coral reef enclosing a central lagoon; forms over submerged volcanic islands
Patch/Platform Reef Isolated, flat-topped reefs found in shallow waters of continental shelves or lagoons

6.2 Coral Reef Distribution in India

India has four major coral reef regions:

Region Reef Type Coral Species Key Features
Gulf of Mannar Fringing 82 species 21 islands between Tuticorin and Rameswaram; Gulf of Mannar Marine National Park; rich pearl oyster beds
Lakshadweep Atoll 91 species 36 coral islands forming atolls; 10 inhabited; most extensive atoll formation in India
Andaman & Nicobar Fringing + Barrier 177 species Highest coral diversity in India; 329 km barrier reef on the west coast; Mahatma Gandhi Marine National Park
Gulf of Kutch Fringing + Platform 36 species Marine National Park in Jamnagar; northernmost coral reef in India; adapted to high turbidity and temperature variation

Patchy reefs are also found along the coast of Ratnagiri and Malvan in Maharashtra.

6.3 Coral Bleaching

Coral bleaching occurs when stressed corals expel their symbiotic zooxanthellae algae, turning white. Main causes include:

  • Rising sea surface temperatures -- even a 1-2 degree C increase above normal triggers bleaching
  • Ocean acidification -- increased CO2 absorption lowers pH, weakening coral skeletons
  • Sedimentation and pollution -- reduces light availability for zooxanthellae
  • El Nino events -- major bleaching events in 1998, 2010, 2016, and 2020 linked to El Nino-driven warming

6.4 Conservation Measures

  • Gulf of Mannar Marine National Park (1986)
  • Mahatma Gandhi Marine National Park, Wandoor (A&N Islands)
  • Marine National Park, Gulf of Kutch (1982)
  • Coral Reef Research and monitoring under the National Coastal Mission
  • India is a member of the International Coral Reef Initiative (ICRI)

Wetlands in India

Wetlands are areas where water covers the soil or is present at or near the surface for varying periods during the year. They act as transitional zones between terrestrial and aquatic ecosystems.

7.1 Types of Wetlands

Type Examples
Inland Natural Lakes, oxbow lakes, floodplains, swamps, marshes
Inland Human-made Reservoirs, tanks, ponds, waterlogged areas
Coastal Natural Mangroves, estuaries, lagoons, backwaters, coral reefs, mudflats
Coastal Human-made Salt pans, aquaculture ponds
High-altitude Pangong Tso, Tso Kar, Tso Moriri (Ladakh); glacial lakes

7.2 Ramsar Convention

The Convention on Wetlands of International Importance, signed at Ramsar, Iran on 2 February 1971, is an intergovernmental treaty providing a framework for the conservation and wise use of wetlands. India signed the Convention in 1982.

Key concepts:

  • Wise Use -- maintaining the ecological character of wetlands while allowing sustainable utilisation
  • Montreux Record -- a register of Ramsar sites where changes in ecological character have occurred or are likely; India's two sites on Montreux Record are Keoladeo National Park (Rajasthan) and Loktak Lake (Manipur)
  • World Wetlands Day -- observed on 2 February each year

7.3 India's Ramsar Sites

As of February 2026, India has 98 Ramsar sites covering approximately 13,60,805 hectares. India ranks third globally (after the United Kingdom with 176 and Mexico with 144) and first in South Asia for number of Ramsar sites.

State-wise top holders:

Important for UPSC

Prelims focus areas:

  • Champion and Seth classification -- 6 major groups, 16 type groups
  • ISFR 2023 data -- total cover (25.17%), top states (MP, Arunachal, Chhattisgarh), mangrove cover (4,992 sq km)
  • Ramsar Convention year (1971), India's accession (1982), total sites (98 as of 2026), Montreux Record sites (Keoladeo, Loktak)
  • Forest Conservation Act 1980 vs. Amendment Act 2023 -- new name, preamble, exemptions
  • FRA 2006 -- 4 hectare limit, Gram Sabha role, eligibility cutoff (13 December 2005)
  • Coral reef types and distribution in India -- atoll only in Lakshadweep, highest diversity in Andaman & Nicobar
  • CAMPA -- 90:10 fund split (State:Centre)

Mains themes:

  • Forest conservation vs. development -- dilemma of diverting forest land for infrastructure (link to FCA 2023 amendment debates)
  • Tribal rights and forest governance -- FRA 2006 implementation challenges, community forest rights
  • Mangrove and wetland ecosystem services -- role in climate resilience, disaster risk reduction
  • Coral bleaching and ocean warming -- impact on marine biodiversity and livelihoods
  • Afforestation quality vs. quantity -- plantation monocultures vs. natural forest regeneration (ISFR data showing VDF increase but MDF/OF decline)
  • Wetland conservation governance -- centralised vs. decentralised approach (2010 rules vs. 2017 rules)

Useful interlinkages:

  • Forest Conservation + Tribal Rights --> GS2 (Social Justice) and GS3 (Environment)
  • Wetlands + Disaster Management --> Mangroves as natural cyclone barriers (GS3)
  • CAMPA + Fiscal Federalism --> Rs. 95,000 crore fund, 90:10 split, utilisation challenges (GS2/GS3)
