What is the primary goal of sustainable agriculture?

  1. Maximizing crop yields

  2. Minimizing environmental impact

  3. Reducing production costs

  4. Increasing profits


Correct Option: B
Explanation:

Sustainable agriculture aims to minimize the negative impact of agricultural practices on the environment, while still maintaining productivity and profitability.

How does sustainable agriculture promote biodiversity?

  1. By using genetically modified crops

  2. By reducing the use of pesticides and fertilizers

  3. By clearing forests for farmland

  4. By planting monocultures


Correct Option: B
Explanation:

Reducing the use of pesticides and fertilizers helps to protect beneficial insects and other organisms that contribute to biodiversity.

What is the role of crop rotation in sustainable agriculture?

  1. To prevent soil erosion

  2. To improve soil fertility

  3. To control pests and diseases

  4. All of the above


Correct Option: D
Explanation:

Crop rotation helps to prevent soil erosion, improve soil fertility, and control pests and diseases, all of which contribute to sustainable agriculture.

Which of the following is an example of a sustainable agricultural practice?

  1. Using drip irrigation

  2. Applying excessive amounts of fertilizer

  3. Clearing wetlands for agriculture

  4. Burning crop residues


Correct Option: A
Explanation:

Drip irrigation is a water-efficient irrigation method that minimizes water waste and reduces the risk of soil erosion.

How does biodiversity contribute to the resilience of agricultural systems?

  1. It increases the susceptibility of crops to pests and diseases

  2. It makes agricultural systems more vulnerable to climate change

  3. It enhances the ability of agricultural systems to adapt to changing conditions

  4. It reduces the productivity of agricultural systems


Correct Option: C
Explanation:

Biodiversity provides a buffer against environmental stresses, such as pests, diseases, and climate change, by increasing the resilience of agricultural systems.

What is the term for the practice of planting a variety of crops in close proximity to each other?

  1. Monoculture

  2. Intercropping

  3. Crop rotation

  4. Agroforestry


Correct Option: B
Explanation:

Intercropping is the practice of planting a variety of crops in close proximity to each other, which can improve soil fertility, reduce pests and diseases, and increase biodiversity.

Which of the following is a benefit of agroforestry?

  1. It increases soil erosion

  2. It reduces water pollution

  3. It decreases biodiversity

  4. It depletes soil nutrients


Correct Option: B
Explanation:

Agroforestry, the integration of trees and shrubs into agricultural systems, can help to reduce water pollution by filtering runoff and preventing soil erosion.

How does sustainable agriculture contribute to food security?

  1. By increasing the use of synthetic fertilizers

  2. By reducing the reliance on fossil fuels

  3. By promoting the use of genetically modified crops

  4. By enhancing the resilience of agricultural systems


Correct Option: D
Explanation:

Sustainable agriculture enhances the resilience of agricultural systems, making them more resistant to shocks and stresses, which contributes to food security.

What is the role of pollinators in sustainable agriculture?

  1. They contribute to soil fertility

  2. They help control pests and diseases

  3. They facilitate the reproduction of plants

  4. They reduce water pollution


Correct Option: C
Explanation:

Pollinators, such as bees and butterflies, play a crucial role in sustainable agriculture by facilitating the reproduction of plants, which is essential for crop production.

How can farmers reduce their reliance on synthetic pesticides and fertilizers?

  1. By increasing the use of genetically modified crops

  2. By adopting integrated pest management practices

  3. By clearing more land for agriculture

  4. By applying excessive amounts of manure


Correct Option: B
Explanation:

Integrated pest management practices, such as crop rotation, biological control, and pest monitoring, can help farmers reduce their reliance on synthetic pesticides and fertilizers.

Which of the following is an example of a sustainable agricultural certification?

  1. Fairtrade

  2. Organic

  3. Rainforest Alliance

  4. All of the above


Correct Option: D
Explanation:

Fairtrade, Organic, and Rainforest Alliance are all examples of sustainable agricultural certifications that promote environmentally friendly and socially responsible farming practices.

How does sustainable agriculture contribute to climate change mitigation?

  1. By increasing greenhouse gas emissions

  2. By reducing deforestation

  3. By promoting the use of fossil fuels

  4. By depleting soil carbon


Correct Option: B
Explanation:

Sustainable agriculture can contribute to climate change mitigation by reducing deforestation, which is a major source of greenhouse gas emissions.

What is the term for the practice of managing agricultural landscapes to enhance biodiversity and ecosystem services?

  1. Agroforestry

  2. Permaculture

  3. Conservation agriculture

  4. Agroecology


Correct Option: D
Explanation:

Agroecology is the practice of managing agricultural landscapes to enhance biodiversity and ecosystem services, such as pollination, pest control, and water regulation.

How can farmers promote soil health in sustainable agriculture?

  1. By reducing tillage

  2. By applying excessive amounts of synthetic fertilizers

  3. By burning crop residues

  4. By clearing forests for agriculture


Correct Option: A
Explanation:

Reducing tillage can help to promote soil health in sustainable agriculture by improving soil structure, increasing organic matter content, and reducing erosion.

What is the role of traditional knowledge in sustainable agriculture?

  1. It is irrelevant in modern agriculture

  2. It can contribute to the development of sustainable agricultural practices

  3. It is outdated and should be discarded

  4. It is harmful to the environment


Correct Option: B
Explanation:

Traditional knowledge, passed down through generations of farmers, can contribute to the development of sustainable agricultural practices that are adapted to local conditions and respect the environment.
