Why are forests important? Give five reasons.

Forests release oxygen as they grow and hold huge amounts of carbon. They are home to a large proportion of the world's land plants and animals. They protect soil from erosion and keep streams and groundwater supplied. They also provide wood, food, fodder and medicines, along with jobs, income and cultural value for many communities.

How do forests help in controlling climate change?

Forests store carbon in wood, roots, leaves, litter and soil. FRA 2025 puts this forest carbon stock at about 714 gigatonnes. A growing forest can also act as a carbon sink, taking in more carbon dioxide than it gives out. When forests are cut or burnt, stored carbon goes back into the air.

What is the difference between deforestation and forest degradation?

Deforestation means forest land is converted to another use, such as farms, mines or towns, so the forest is gone. Degradation means the forest still stands but has become poorer, with fewer trees, damaged soil or less wildlife. Both reduce the benefits a forest can give.

How can students help protect forests?

Students can plant and care for native saplings, save paper, avoid starting fires near forests, and learn about local conservation laws. They can also join school eco-clubs, visit nature camps, and talk to their families about wasting less wood and buying products that do not come from cleared forest.

Importance of Forests: Why Forests Matter to People and the Planet

Q: How much of the world is covered by forest?

According to FAO's Global Forest Resources Assessment 2025, forests cover 4.14 billion hectares. That is about 32 per cent of the world's land area, or roughly half a hectare of forest for every person. The tropical domain holds the biggest share, 45 per cent of all forests.

Why are forests important? Forests are important because they keep the planet’s air, water, soil and climate healthy. They are home to a large proportion of the world’s land plants and animals. They also feed, house and employ millions of people. In short, forests support life on Earth in ecological, economic and social ways.

This page is the main guide to forests and their value on this site. It explains each role of forests briefly, then points you to a detailed article for every sub-topic. Start here, then follow the links for exam-level depth.

What is a forest?

A forest is a large area of land where trees are the main kind of plant and their tops, the canopy, shade much of the ground. Rainforests, deciduous forests, conifer forests and mangroves differ a lot in climate and plant life. Our guide to types of forests and their role explains each kind in detail.

How much of the world is covered by forests?

Global forest figures come from the Global Forest Resources Assessment (FRA) of the Food and Agriculture Organization (FAO). FAO publishes it every five years. The latest edition is FRA 2025, released on 21 October 2025 and covering 236 countries and areas.

According to FRA 2025, forests cover 4.14 billion hectares. This is about 32 per cent of the global land area. It works out to roughly 0.50 hectare of forest per person. The tropical domain holds 45 per cent of the world’s forests.

Forests are spread very unevenly. FRA 2025 reports that just five countries hold 54 per cent of all forests. In order of area, these are Russia, Brazil, Canada, the United States and China. Europe has the largest regional forest area, with a quarter of the world total. South America has the highest proportion of its land under forest, at 49 per cent.

How does India compare?

India reports its own figures through the Forest Survey of India. According to ISFR 2023, India’s forest cover is 7,15,342.61 km², which is 21.76% of its geographical area. Tree cover outside forests adds another 1,12,014.34 km² (3.41%). Together, forest and tree cover make up 8,27,356.95 km², or 25.17% of the country.

In ISFR 2023, FSI counts as forest cover all land of one hectare or more with a tree canopy density of 10% or more. It then splits this cover into three density classes. Very dense forest has a canopy density of 70% or more. Moderately dense forest lies between 40% and 70%. Open forest, the least dense class, has 10% to under 40%. Forest land with canopy below 10% is called scrub.

Why are forests important for the environment?

The ecological role of forests is the one most asked about in exams. Forests work like a giant life-support system. FAO notes that forests are habitat for a large proportion of the world’s biodiversity. They also help to regulate the global carbon and water cycles.

Forests release oxygen and store carbon

Green leaves use sunlight, water and carbon dioxide to make food. This process is called photosynthesis. As forests grow, photosynthesis releases oxygen into the air. The carbon taken in is built into wood, roots and leaves, and some of it passes into the soil.

The total carbon held in a forest is called its carbon stock. According to FRA 2025, the world’s forests store about 714 gigatonnes of carbon. Of this, 46 per cent lies in soil and 44 per cent in living trees and roots. The remaining 10 per cent is in litter and dead wood.

A carbon sink is a different idea. It describes a flow, not a store. A forest acts as a sink while it takes in more carbon than it gives out, for example while young trees are growing. A forest that is burnt or felled can turn into a source of carbon instead.

Forests protect soil

Tree roots bind soil particles together. Fallen leaves form a soft layer of litter that cushions raindrops. As a result, less soil is washed or blown away. When forests on slopes are cleared, the topsoil is lost quickly and landslides become more likely.

Forests regulate water

A forest acts like a sponge. Rainwater soaks slowly into the forest floor and recharges groundwater. Streams then keep flowing in the dry season. Trees also release water vapour through their leaves, a process called transpiration. This adds moisture to the air and can influence local rainfall.

FAO’s report on FRA 2025 says forests can reduce the risks of drought, floods, soil erosion, landslides and desertification. FRA 2025 also finds that 386 million hectares of forest are managed mainly to protect soil and water.

Forests are home to wildlife

Forests have many layers, from the canopy to the floor. Each layer offers different food and shelter. Birds nest high in the crowns, while deer, insects and fungi use the shady floor. This variety of niches is why a single forest can hold so many kinds of living things.

For a full list of these benefits, read our guide to forest ecosystem services, covered in the next section.

What are the ecosystem services of forests?

Ecosystem services are the benefits that people receive free from nature. Scientists group them into four types. Provisioning services are products such as wood and food. Regulating services control climate, water and disease. Cultural services include recreation and spiritual value. Supporting services, like soil formation and nutrient cycling, keep the other three going.

This framework is useful in college exams and essays. It turns a long list of benefits into four tidy groups. Our article on forest ecosystem services: provisioning, regulating, cultural and supporting explains each group with Indian examples.

What resources do we get from forests?

Forests are a storehouse of useful materials. NCERT’s Class 9 textbook Understanding Society: India and Beyond lists food, fuel, fodder, medicine, shelter, timber, bamboo and firewood. It also highlights non-timber forest products (NTFPs) such as honey, fruits, nuts, resins and medicinal plants.

Forest resources are often split into major produce (timber and fuelwood) and minor produce (everything else). The word “minor” can mislead. For many forest families, honey, tendu leaves and mahua flowers matter more than timber. Read forest resources: types, uses and economic value for a full breakdown.

Why are forests important for the economy?

Forests support whole industries. Timber goes into furniture, construction, paper and plywood. Bamboo, cane and grasses feed handicraft and cottage industries. Gums, resins, dyes and medicinal plants supply the pharmaceutical and cosmetic trades.

FRA 2025 shows how much forest is set aside for production. About 1.20 billion hectares, or 29 per cent of all forest, is managed mainly to produce wood and non-wood products. A further 616 million hectares is designated for multiple use, which often includes production.

Forests also earn money through ecotourism. NCERT’s Class 9 textbook names Uttarakhand, Assam and Kerala as Indian examples. Tourists pay for guides, homestays and park entry. Done well, this gives local people a reason to protect the forest.

Some forest goods carry a Geographical Indication (GI) tag. A GI tag shows that a product’s quality is linked to the place it comes from. Kandhamal Haldi from Odisha and Channapatna toys from Karnataka are forest-linked GI products named by NCERT.

Why are forests important for people and society?

For many communities, a forest is far more than a resource. NCERT’s Class 9 textbook explains that rural and tribal communities rely heavily on forests for their livelihoods. Groups such as the Gonds and Bhils also perform rituals to honour forest deities.

Livelihoods of forest dwellers

Forest dwellers gather tendu leaves, mahua flowers, honey, lac and bamboo to earn income. Women play a key role in collecting firewood, fodder, wild fruits and medicinal plants. They also carry traditional knowledge from one generation to the next.

Culture, faith and sacred groves

Many Indian communities protect small patches of forest for religious reasons. These are called sacred groves. They have local names such as Devrai, Devarakadu, Kavu and Sarna. Because nobody cuts them, sacred groves often keep rare plants and medicinal species alive.

Health, recreation and learning

Forests offer clean air, quiet and space to walk, trek and watch birds. FRA 2025 records 221 million hectares of forest allocated mainly to social services. These include recreation, tourism, education, research and the protection of cultural and spiritual sites.

What are the main threats to forests?

Forests face both natural and human threats. Clearing for farms and towns, fire, mining, road building and poaching all take a toll. NCERT’s Class 9 textbook adds that forested hills are prone to floods and landslides. The two biggest threats for exams are deforestation and fire.

FRA 2025 adds insects, diseases and severe weather to the list. In 2020 these damaged about 41 million hectares of forest, mostly in the temperate and boreal zones.

Forest fires

A forest fire is an uncontrolled fire that spreads through trees, shrubs and dry litter. NCERT’s Class 9 textbook names climate change and human-induced factors as the main reasons for such fires. It also notes that human care and preventive measures can stop many of them. Quick detection and public awareness are the main control tools.

According to FRA 2025, fire affected an average of 261 million hectares of land each year in 2007-2019. Almost half of this burnt land (49 per cent) was forest. In 2019 alone, about 123 million hectares of forest burnt, and 79 per cent of it lay in the subtropical domain. Learn more in forest fires: causes, effects and prevention.

Deforestation

Deforestation is the permanent clearing of forest so that the land can be used for something else. Farms, pastures, mines, dams, roads and towns are common replacements. As human numbers grow, the demand for farmland and timber keeps pushing into forest land.

According to FRA 2025, about 489 million hectares of forest have been lost to deforestation since 1990. The rate has slowed, from 17.6 million hectares a year in 1990-2000 to 10.9 million hectares a year in 2015-2025. FAO still calls the current rate too high. Our guide to deforestation: meaning and causes explains the drivers one by one.

What happens when forests are cut down?

Losing a forest sets off a chain of damage. Without roots to hold it, soil washes into rivers and silts up dams. Streams may dry up in summer and flood in the monsoon. Animals lose their homes and food, and some species may die out.

The climate is affected too. Cutting and burning trees releases stored carbon back into the air as carbon dioxide. Local temperatures can rise once the shade and moisture of the canopy are gone. Forest families also lose their income and their way of life.

Each of these effects deserves careful study. Read effects of deforestation on the environment for the full list with examples.

How can we stop deforestation?

There is no single solution, but many tools work together. Governments can protect forests by law and set up national parks and sanctuaries. Communities can manage nearby forests and share their benefits. Consumers can choose recycled paper and certified wood.

FRA 2025 shows some progress. About 813 million hectares of forest, roughly 20 per cent of the total, now lie in legally protected areas. More than half of all forests, 2.13 billion hectares, are covered by long-term management plans. Explore practical answers in how to stop deforestation: 12 solutions that work.

What is afforestation and how is it different from reforestation?

Afforestation means planting trees on land that has not had forest for a long time, such as bare hillsides or wasteland. Reforestation means replanting trees where a forest was recently cut or burnt. Both increase tree cover, but they start from different kinds of land.

Feature	Afforestation	Reforestation
Starting land	Land without forest for a long time	Land where forest was recently lost
Main aim	Create a new forest	Restore a lost forest
Typical sites	Barren hills, wasteland, roadsides	Logged, burnt or cleared forest land
Example in India	Social forestry on degraded land	Replanting after a forest fire

Social forestry, which plants trees on village common land, roadsides and wasteland, is a well-known Indian approach to afforestation. Read what is afforestation? meaning, examples and benefits for details. For a side-by-side comparison, see afforestation vs reforestation: differences and examples.

Planting is not the whole answer, though. FRA 2025 reports that naturally regenerating forests make up 92 per cent of the world’s forest area. Protecting these older forests often does more good than planting new ones.

How are forests conserved?

Forest conservation means using and protecting forests so that they last for future generations. It tries to balance the needs of nature with the needs of people who live in and around forests.

Key methods include protected areas, controlled felling, fire control, social forestry and community management. The Joint Forest Management (JFM) programme lets villagers protect forests while sharing forest produce. The Forest Rights Act, 2006 recognises the traditional rights of forest-dwelling communities.

NCERT’s Class 9 textbook gives a strong example. Mendha Lekha, a Gond village in Gadchiroli, Maharashtra, was the first in India to gain rights over its forest under the Forest Rights Act. The Gram Sabha controls tree cutting, prevents fires and harvests bamboo sustainably. Read forest conservation: methods and importance for more methods.

What was the Chipko Movement?

The Chipko Movement was a people’s campaign to save trees in the hills of present-day Uttarakhand (then Uttar Pradesh). “Chipko” means “to hug” or “to cling”. When forest contractors came to fell trees, villagers, including many women, hugged the trees to stop the felling.

Local activists led the campaign. The Government of India describes Chandi Prasad Bhatt as one of the pioneers of the Chipko movement. NCERT’s Class 12 sociology book tells how Gaura Devi, head of the village women’s club in Reni, gathered other women and faced the loggers until they left. The book also shows that villagers depended on these forests for firewood and fodder.

NCERT’s Class 9 textbook links Chipko to the earlier Bishnoi Movement in Rajasthan, led by Amrita Devi. Both show that ordinary forest communities can protect forests. Chipko is a favourite exam topic. Our article on the Chipko Movement: history, leaders and impact covers the full story.

Where can I find an essay on the importance of forests?

Many school exams ask for an essay or paragraph on this topic. This page is a study guide, so it does not use essay format. For ready-to-learn essays of 150, 200 and 500 words, see our essay on importance of forests.
