Deforestation and Land Degradation Questions

Multiple choice

Which of the following is NOT a potential negative consequence of forest fragmentation?

  1. Loss of Biodiversity

  2. Increased Carbon Emissions

  3. Enhanced Soil Fertility

  4. Reduced Risk of Forest Fires
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Forest fragmentation typically leads to a decline in soil fertility, as the loss of forest cover can result in soil erosion and nutrient depletion. Enhanced soil fertility is not a potential negative consequence of forest fragmentation.

Multiple choice

Which of the following is NOT a potential strategy for reducing deforestation?

  1. Promoting Sustainable Agriculture

  2. Expanding Protected Areas

  3. Encouraging Agroforestry Practices

  4. Increasing Timber Prices
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Increasing timber prices is not a potential strategy for reducing deforestation. While higher timber prices may provide an incentive for forest owners to manage their forests sustainably, they can also lead to increased deforestation as forest owners may be tempted to clear more forests to take advantage of the higher prices.

Multiple choice

What is the main cause of deforestation in India?

  1. Agriculture

  2. Industrialization

  3. Mining

  4. Urbanization

  4. War and conflict
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Natural disasters, such as floods, droughts, and wildfires, are the primary cause of environmental displacement, forcing people to leave their homes and communities.

Multiple choice

What is the primary cause of soil alkalinity in India?

  1. Excessive irrigation

  2. High rainfall

  3. Intensive agriculture

  4. Deforestation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Excessive irrigation, particularly with water high in salts, can lead to the accumulation of salts in the soil, resulting in soil alkalinity.
