Deforestation is the process of clearing or
removing forests or trees from a particular area, typically for
various human activities such as agriculture, urban
development, commercial logging, or mining. This practice
results in the loss of forest cover, which can have significant
environmental consequences, including habitat destruction,
reduced biodiversity, climate change (due to the release of
stored carbon dioxide), and disruption of local ecosystems.
Deforestation is a global environmental concern, and efforts
are made worldwide to mitigate its negative impacts and
promote sustainable forest management.

1. Agricultural expansion: One of the main drivers of deforestation in India is the
expansion of agricultural land. As the population grows, there is increasing demand for
food, leading to the conversion of forest land into fields and pastures.
2. Infrastructure development: The construction of roads, buildings, and other
infrastructure projects often requires the clearing of forests.
3.Commercial Logging: The demand for wood and other forest products, such as paper,
fuel, and furniture, drives logging and deforestation.
4. Mining and Dam : The extraction of minerals and other resources from forests can
lead to deforestation.
5. Human settlement: As people move into forested areas, they often clear the land for
housing, agriculture, and other purposes, leading to deforestation.
6. Government policies: Government policies and incentives can also contribute to
deforestation, either directly or indirectly. For example, policies that promote agricultural
expansion or resource extraction may lead to the clearing of forests.

• It cause the bio-diversity leading to disturbance in
ecological balance world wide.
• Forests are home to countless species of plants,
animals, and microorganisms. Deforestation destroys
their habitats, leading to the loss of biodiversity. Many
species are unable to survive without their natural
habitats, which can result in their extinction.

Deforestation contributes to climate change in several ways.
Forests act as carbon sinks, absorbing carbon dioxide from the
atmosphere as they grow. When forests are cleared or burned, the
stored carbon is released back into the atmosphere as carbon dioxide,
contributing to global warming. The loss of forests also reduces the
planet’s capacity to absorb carbon dioxide from the atmosphere, further
exacerbating climate change.
The report estimated that in less than 10 years, 45-64 percent of India’s
forest cover will be covered under climate change hotspots and by 2050 it will
extend to the entire Indian forest cover.

• Deforestation also affects human communities and livelihoods, as
forests are a source of oxygen, food, clean water, and medicine.
– Globally, forests are home to approximately 30,00,00,000 human
beings. They are also a source of raw material for many
commercially important products such as paper, wood, and fabric.
– Approximately 1.6 billion jobs are forest-dependent.
– Deforestation also increases the frequency and severity of flooding
events, as trees and natural vegetation help to hold soil in place and
regulate the water cycle.
• A study found that felling large areas of forest in snowy regions can
double or even quadruple the number of large floods around the
streams and rivers that pass through those forests

Forests play a crucial role in
regulating the water cycle by
absorbing rainfall and releasing it
gradually. Deforestation disrupts this
cycle, leading to changes in patterns
of weather and water availability

• To control deforestation, we can take measures such as
afforestation, which involves growing trees in the forest to
replace those that have been cut down. We can also
increase the use of plant-based products to reduce the
demand for wood-based products. Governments can also
implement policies and regulations to protect forests and
encourage sustainable forest management practices

– Deforestation is a major threat to India’s biodiversity and climate
stability.
– It has negative impacts on wildlife, ecosystems, human health, and
economy.
– Deforestation can be controlled by implementing policies and laws
that protect forests and regulate land use.
– Reforestation and afforestation are also important strategies to
restore forest cover and mitigate the effects of deforestation.
– Promoting sustainable agriculture and forestry practices can also
help to reduce deforestation and its impacts.
