What is the primary cause of deforestation?

  1. Natural disasters

  2. Agricultural expansion

  3. Urbanization

  4. Climate change


Correct Option: B
Explanation:

Agricultural expansion, particularly for large-scale farming and cattle ranching, is the leading cause of deforestation worldwide.

Which of the following is NOT a consequence of deforestation?

  1. Loss of biodiversity

  2. Increased soil erosion

  3. Enhanced carbon sequestration

  4. Disruption of water cycles


Correct Option: C
Explanation:

Deforestation reduces carbon sequestration by removing trees that absorb and store carbon dioxide from the atmosphere.

What is agroforestry?

  1. A system of agriculture that integrates trees and crops

  2. A method of farming that uses only organic fertilizers

  3. A technique for increasing crop yields through genetic modification

  4. A practice that involves clearing forests for agricultural purposes


Correct Option: A
Explanation:

Agroforestry is a sustainable land management system that combines the cultivation of crops with the planting of trees and shrubs.

How does agroforestry contribute to deforestation prevention?

  1. By providing alternative sources of income for farmers

  2. By reducing the need for new agricultural land

  3. By improving soil fertility and water retention

  4. All of the above


Correct Option: D
Explanation:

Agroforestry offers farmers economic incentives to conserve forests, reduces the pressure to clear new land for agriculture, and enhances the resilience of agricultural systems to environmental challenges.

Which of the following is NOT a benefit of agroforestry?

  1. Increased biodiversity

  2. Improved soil health

  3. Reduced water pollution

  4. Increased vulnerability to pests and diseases


Correct Option: D
Explanation:

Agroforestry systems are generally more diverse and resilient than monocultures, making them less susceptible to pest and disease outbreaks.

What is the role of agroforestry in climate change mitigation?

  1. It reduces greenhouse gas emissions by sequestering carbon in trees.

  2. It helps regulate the Earth's temperature by providing shade and evapotranspiration.

  3. It improves soil carbon storage and reduces soil erosion.

  4. All of the above


Correct Option: D
Explanation:

Agroforestry systems contribute to climate change mitigation by sequestering carbon, regulating temperature, and improving soil health.

Which of the following is NOT an example of an agroforestry system?

  1. Silvopasture (integrating trees with livestock grazing)

  2. Alley cropping (planting trees or shrubs between crop rows)

  3. Forest farming (harvesting non-timber forest products)

  4. Monoculture farming (growing a single crop on a large scale)


Correct Option:
Explanation:

Monoculture farming, which involves growing a single crop on a large scale, is not considered an agroforestry system due to its lack of diversity and integration of trees.

What are some challenges associated with implementing agroforestry?

  1. Lack of technical knowledge and skills among farmers

  2. Limited access to financial resources and credit

  3. Cultural and social barriers to adopting new farming practices

  4. All of the above


Correct Option: D
Explanation:

Implementing agroforestry can be challenging due to a combination of technical, financial, and socio-cultural factors.

Which of the following is NOT a potential solution to deforestation?

  1. Promoting sustainable agriculture practices, including agroforestry

  2. Reducing the demand for forest products through responsible consumption

  3. Strengthening forest governance and law enforcement

  4. Expanding protected areas without considering the needs of local communities


Correct Option: D
Explanation:

Expanding protected areas without considering the needs and rights of local communities can lead to conflicts and undermine conservation efforts.

What is the role of international cooperation in addressing deforestation?

  1. Establishing global agreements and targets for forest conservation

  2. Providing financial and technical assistance to developing countries

  3. Promoting trade policies that support sustainable forest management

  4. All of the above


Correct Option: D
Explanation:

International cooperation is essential for addressing deforestation, as it requires coordinated efforts to reduce demand, promote sustainable practices, and support forest conservation initiatives.

Which of the following is NOT a benefit of agroforestry for smallholder farmers?

  1. Increased crop yields and diversification of income sources

  2. Improved soil fertility and water conservation

  3. Reduced vulnerability to climate change and extreme weather events

  4. Increased risk of crop failure due to competition with trees


Correct Option: D
Explanation:

Agroforestry systems are designed to optimize the interactions between trees and crops, minimizing competition and maximizing benefits.

What is the term used to describe the process of converting degraded or barren land into productive agricultural land?

  1. Reforestation

  2. Agroforestry

  3. Afforestation

  4. Silviculture


Correct Option: C
Explanation:

Afforestation refers to the process of planting trees on land that has not been forested recently, often involving the conversion of degraded or barren land into productive agricultural or forest land.

Which of the following is NOT a key component of sustainable agroforestry practices?

  1. Crop diversification and integration of trees

  2. Use of chemical fertilizers and pesticides

  3. Soil and water conservation measures

  4. Management of pests and diseases through ecological methods


Correct Option: B
Explanation:

Sustainable agroforestry practices emphasize the use of natural methods for pest and disease management, minimizing the reliance on chemical inputs.

What is the term used to describe the practice of planting trees in rows or strips within agricultural fields?

  1. Silvopasture

  2. Alley cropping

  3. Forest farming

  4. Agroforestry


Correct Option: B
Explanation:

Alley cropping is a specific agroforestry technique that involves planting trees or shrubs in rows or strips within agricultural fields, providing benefits such as shade, windbreaks, and improved soil fertility.

Which of the following is NOT a potential benefit of agroforestry for biodiversity conservation?

  1. Providing habitat and food sources for a variety of species

  2. Reducing habitat fragmentation and creating corridors for wildlife

  3. Increasing genetic diversity and resilience of ecosystems

  4. Promoting the spread of invasive species


Correct Option: D
Explanation:

Agroforestry systems are designed to enhance biodiversity and provide habitat for native species, rather than promoting the spread of invasive species.
