1.3. FOREST RESOURCES

Forests are one of the most important natural resources and a part of biosphere since these are natural assets on this earth. Forests predominantly composed of trees, shrubs, woody vegetation etc… Approximately 1/3rd of the earth’s total land area is covered by forests. Forests are important ecologically and economically. Ecologically forests are to be considered as earth’s lungs because they consume CO₂ and release O₂ which is required for sustaining the life on this earth. The poisonous gas CO₂ is absorbed by the trees of forests and reduces the global warming and helps to continue hydrological cycle, reduce soil erosion. Forest ecosystems are extremely good & hold a good quantity of water.

Forests play a crucial role in maintaining ecological balance on Earth. They cover about one-third of the planet's land area and are vital for life. Trees in forests take in carbon dioxide (CO₂), a greenhouse gas, and release oxygen (O₂), which is essential for the survival of most living beings. This process makes forests often referred to as the 'lungs of the Earth.' Additionally, forests aid in regulating the water cycle, preventing soil erosion, and contributing to the overall health of the environment.

Think of forests as a giant air filter. Just like how an air filter cleans the air in our homes by removing dust and pollutants while providing us with fresh, breathable air, forests filter the air on a global scale. They absorb harmful gases like CO₂ and release clean oxygen for us to breathe.

Economically forests provide timber, fodder to grazing animals, firewood (conventional fuel), bamboos, rubbers, medicines, gums, resins, food items etc.

Forests serve several economic purposes. They provide timber for construction and furniture-making, fodder for livestock, and firewood for cooking. Additionally, forests are a source of non-timber products such as rubber, medicinal plants, and various foods. The diversity of resources available in forests supports local economies and provides livelihoods for many people, particularly those living in rural areas.

Imagine a supermarket filled with a variety of products. Each aisle has something different: one for grains, another for dairy, and another for fresh produce. Similarly, forests are like a supermarket of natural resource products; they supply us with a range of materials that we use in our daily lives, from building materials to food and medicines.

1. Watershed protection: • Reduce the rate of surface run-off of water. • Prevent flash floods and soil erosion. • Produces prolonged gradual run-off and thus prevent effects of drought. 2. Atmospheric regulation: • Absorption of solar heat during evapo-transpiration. • Maintaining carbon dioxide levels for plant growth. • Maintaining the local climatic conditions. 3. Erosion control: • Holding soil (by preventing rain from directly washing soil away). 4. Land bank: • Maintenance of soil nutrients and structure.

Forests play a vital role in environmental protection. They protect watersheds by controlling the flow of water, minimizing flash floods and preventing soil erosion. During heavy rains, the trees and undergrowth absorb water, allowing it to seep gradually into the ground rather than running off quickly and washing away soil. Additionally, through processes like evapo-transpiration, forests help regulate local climates and maintain the balance of gases in the atmosphere, which is essential for plant growth.

Think of forests as nature's sponge. Just like a sponge absorbs water and releases it slowly, forests soak up rainwater, preventing flooding and retaining moisture in the soil, which is beneficial during dry spells. Without this 'sponge effect,' our lands would suffer more frequent flooding and droughts.

Exploitation of forest has taken place to meet human demands in the following ways: - Due to wood cutting and large scale logging for raw materials like timber, pulp wood, fuel wood etc - Deforestation due to road construction - Clearing of forest to create more agricultural lands to meet the food needs of growing population - Encroachment of forests leading to destruction of about 19.57 lakh hectares (2013) of forest in the country - About 78% of forest area is under heavy grazing - Mining activities leads to clearing of forests - Big hydro electric projects result in large scale destruction of forest.

Over-exploitation of forests refers to the unsustainable practices that lead to the degradation and reduction of forest areas. This includes activities such as logging for timber, converting forest land into agricultural areas, and building infrastructure like roads. Encroachment, excessive grazing, and mining also contribute to forest loss. As human populations grow, the demand for land and resources increases, leading to pressures on these vital ecosystems.

Imagine you have a beautiful garden. If every day you pick flowers, cut plants to make space for a swing, and have your pets running all over, eventually your garden will lose its beauty and health. Similarly, when we exploit forests without care, we threaten their ability to thrive, ultimately losing valuable ecosystems.

Deforestation is the permanent destruction of indigenous forests and woodlands. The term does not include the removal of industrial forests such as plantations of gums or pines. Deforestation has resulted in the reduction of indigenous forests to four-fifths of their pre-agricultural area. Indigenous forests now cover 21% of the earth's land surface. Deforestation refers to the loss of forest cover (or) the aimless destruction of trees. The clearing of forests across the earth has been occurring on a large scale basis for many centuries. This process involves the cutting down, burning and damaging of forests. Currently 12 million hectares of forests are cleared annually and the current rate of deforestation continues, the world’s forests will vanish within the next 100 years about 80% of the original forests on the earth have already been cleared.

Deforestation refers to the complete removal of forests and woodlands, often to make way for agriculture, urban development, or logging. It can have devastating impacts on biodiversity, climate change, and the balance of ecosystems. Currently, a significant portion of the world's forests is lost every year due to human activities, which threatens the existence of many species and the overall health of our planet.

Consider a jigsaw puzzle: each piece represents an important part of an ecosystem. If you remove too many pieces, the image becomes incomplete and eventually unsolvable. Deforestation removes vital pieces from our ecological puzzle, leading to a fragmented and less resilient environment.
