What is the primary focus of agroecology?

  1. Maximizing crop yields

  2. Reducing the use of synthetic pesticides and fertilizers

  3. Promoting biodiversity in agricultural systems

  4. All of the above


Correct Option: D
Explanation:

Agroecology aims to create sustainable agricultural systems that are in harmony with the natural environment. This includes practices such as crop rotation, cover cropping, and integrated pest management, all of which contribute to increased biodiversity and reduced reliance on synthetic inputs.

Which of the following is NOT a benefit of agroecological practices?

  1. Increased soil fertility

  2. Reduced water pollution

  3. Higher yields

  4. Increased vulnerability to pests and diseases


Correct Option: D
Explanation:

Agroecological practices typically promote biodiversity and enhance the natural resilience of agricultural systems, making them less susceptible to pests and diseases.

What is the term for the practice of growing different crops in sequence on the same land?

  1. Crop rotation

  2. Monoculture

  3. Intercropping

  4. Agroforestry


Correct Option: A
Explanation:

Crop rotation is a fundamental agroecological practice that helps to maintain soil fertility, control pests and diseases, and improve overall crop health.

Which of the following is an example of an agroecological pest management strategy?

  1. Using synthetic pesticides

  2. Releasing beneficial insects

  3. Applying chemical fertilizers

  4. Burning crop residues


Correct Option: B
Explanation:

Releasing beneficial insects, such as ladybugs or lacewings, is a biological pest control method that is commonly used in agroecological systems.

What is the term for the practice of growing trees and shrubs alongside crops?

  1. Agroforestry

  2. Silvopasture

  3. Alley cropping

  4. All of the above


Correct Option: D
Explanation:

Agroforestry, silvopasture, and alley cropping are all practices that involve integrating trees and shrubs into agricultural systems. These practices provide multiple benefits, including improved soil fertility, increased biodiversity, and enhanced carbon sequestration.

Which of the following is a key principle of agroecology?

  1. Working with nature rather than against it

  2. Maximizing short-term profits

  3. Using synthetic inputs to boost yields

  4. Ignoring the social and economic aspects of agriculture


Correct Option: A
Explanation:

Agroecology emphasizes the importance of working in harmony with natural ecosystems to create sustainable agricultural systems. This includes practices that mimic natural processes and promote biodiversity.

What is the term for the practice of managing livestock on pasture in a way that mimics the grazing patterns of wild herbivores?

  1. Holistic grazing

  2. Rotational grazing

  3. Continuous grazing

  4. Zero grazing


Correct Option: A
Explanation:

Holistic grazing is a management approach that aims to mimic the natural grazing behavior of wild herbivores. This involves moving livestock frequently to different parts of the pasture, allowing the vegetation to recover and maintain its diversity.

Which of the following is an example of an agroecological soil management practice?

  1. Applying synthetic fertilizers

  2. Using cover crops

  3. Tilling the soil frequently

  4. Leaving crop residues on the field


Correct Option: B
Explanation:

Cover crops are plants that are grown to cover the soil and protect it from erosion. They also help to improve soil fertility and biodiversity.

What is the term for the practice of managing water resources in agricultural systems?

  1. Water conservation

  2. Irrigation

  3. Drainage

  4. All of the above


Correct Option: D
Explanation:

Water management in agroecological systems involves a combination of practices to conserve water, improve irrigation efficiency, and manage drainage to prevent waterlogging.

Which of the following is NOT a challenge to the adoption of agroecological practices?

  1. Lack of knowledge and technical support

  2. Economic barriers

  3. Social and cultural barriers

  4. Government policies that favor conventional agriculture


Correct Option: A
Explanation:

While lack of knowledge and technical support can be a barrier to the adoption of agroecological practices, it is not a challenge that is unique to agroecology. Economic barriers, social and cultural barriers, and government policies that favor conventional agriculture are all significant challenges that need to be addressed.

What is the term for the practice of integrating livestock and crop production in the same system?

  1. Agroforestry

  2. Silvopasture

  3. Integrated farming

  4. All of the above


Correct Option: C
Explanation:

Integrated farming is a holistic approach to agriculture that combines crop production, livestock production, and other agricultural activities in a mutually beneficial way.

Which of the following is a key goal of agroecology?

  1. Increasing yields

  2. Reducing environmental impacts

  3. Improving food quality and safety

  4. All of the above


Correct Option: D
Explanation:

Agroecology aims to achieve multiple goals simultaneously, including increasing yields, reducing environmental impacts, and improving food quality and safety.

What is the term for the practice of managing pests and diseases without the use of synthetic pesticides?

  1. Biological control

  2. Cultural control

  3. Chemical control

  4. Physical control


Correct Option: A
Explanation:

Biological control involves the use of natural enemies, such as predators, parasites, and pathogens, to control pests and diseases.

Which of the following is NOT a benefit of agroecological practices for farmers?

  1. Increased resilience to climate change

  2. Reduced production costs

  3. Improved soil health

  4. Increased vulnerability to pests and diseases


Correct Option: D
Explanation:

Agroecological practices typically promote biodiversity and enhance the natural resilience of agricultural systems, making them less susceptible to pests and diseases.

What is the term for the practice of managing agricultural systems in a way that mimics natural ecosystems?

  1. Permaculture

  2. Natural farming

  3. Biodynamic agriculture

  4. All of the above


Correct Option: D
Explanation:

Permaculture, natural farming, and biodynamic agriculture are all approaches to agriculture that aim to mimic the structure and function of natural ecosystems.
