Which of the following may result to forest denudation?
Deforestation is a primary cause of human-caused carbon dioxide emissions leading to global warming. All forests contain large amounts of carbon. Therefore, higher concentrations of atmospheric carbon dioxide lead to a warmer climate. Global warming threatens ecosystems and biodiversity globally.
Where does forest deforestation happen?
95% of global deforestation occurs in the tropics. Brazil and Indonesia alone account for almost half. After long periods of forest clearance in the past, most of today’s richest countries are increasing tree cover through afforestation.
How does forest degradation occur?
There are a few main drivers of forest degradation. One is climate change: higher temperatures and unpredictable weather patterns increase the risk and severity of forest fires, pest infestation, and disease. But the main cause of forest degradation is unsustainable and illegal logging.
What’s happening to forests in the Philippines?
Aside from logging (whether legal or illegal), other causes of deforestation in the Philippines are forest fires, “kaingin” farming (slash-and-burn agriculture), and mining operations. Volcanic eruptions have also devastated some of the country’s tropical rainforests.
What is the meaning of forest denudation?
Answer: Forest Denudation – to strip a forest by depriving it of something it needs in order to exist. For example, to strip it’s surface layers, in some cases by erosion. Commonly through a ripping and burning process to create farmland. Also when harvesting Native forests for timber in an unsustainable fashion.
What is effects of forest?
Forest improves the environment in many ways such as: Relative humidity of air is increased. increase fertility of surface soil. These add large quantities of organic matter in soil by which water and nutrient holding capacity of soil is increased. Domestic animals as well.
What are the causes and consequences of forest degradation?
The loss forest cover influences the climate and contributes to a loss of biodiversity. The economic activity is adversely affected by siltation, flooding, soil degradation and reduced timber supplies.
How much forest is left in the Philippines?
The forest area of the Philippines is estimated to have declined from 12 million hectares in 1960 to a current level of about 5.7 million hectares (which includes less than 1 million hectares of virgin forest largely confined to very steep and inaccessible areas).
How can we protect forest?
Some of the steps we can take to conserve our forest resources are as follows:
- Regulated and Planned Cutting of Trees:
- Control over Forest Fire:
- Reforestation and Afforestation:
- Check over Forest Clearance for Agricultural and Habitation Purposes:
- Protection of Forests:
- Proper Utilisation of Forest and Forests Products:
