How does climate change affect agricultural productivity?

  1. Increased crop yields due to higher temperatures

  2. Reduced water availability leading to crop failure

  3. Enhanced soil fertility due to increased carbon dioxide levels

  4. Improved pest resistance in crops due to warmer climate


Correct Option: B
Explanation:

Climate change often leads to changes in precipitation patterns, resulting in droughts and water scarcity, which can severely impact crop yields and agricultural productivity.

Which greenhouse gas is primarily responsible for the rise in global temperatures?

  1. Carbon dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous oxide (N2O)

  4. Hydrofluorocarbons (HFCs)


Correct Option: A
Explanation:

Carbon dioxide (CO2) is the primary greenhouse gas contributing to global warming. It is released into the atmosphere through human activities such as burning fossil fuels and deforestation.

How does climate change affect the frequency and intensity of extreme weather events?

  1. It increases the likelihood of more frequent and severe droughts

  2. It reduces the occurrence of heatwaves and wildfires

  3. It leads to a decrease in the intensity of hurricanes and cyclones

  4. It results in milder winters and less snowfall


Correct Option: A
Explanation:

Climate change is associated with an increase in the frequency and severity of extreme weather events, including droughts, heatwaves, wildfires, and storms.

Which agricultural practice can help reduce greenhouse gas emissions?

  1. Conventional tillage

  2. Crop rotation

  3. Synthetic fertilizer application

  4. Rice cultivation with continuous flooding


Correct Option: B
Explanation:

Crop rotation is an agricultural practice that involves growing different crops in the same area in sequential seasons. It helps improve soil health, reduce the need for synthetic fertilizers, and mitigate greenhouse gas emissions.

How can farmers adapt to the impacts of climate change on agriculture?

  1. Switching to drought-resistant crop varieties

  2. Increasing irrigation water usage

  3. Using more synthetic fertilizers to boost crop yields

  4. Clearing forests to expand agricultural land


Correct Option: A
Explanation:

Switching to drought-resistant crop varieties is an effective adaptation strategy for farmers facing water scarcity due to climate change. These varieties can withstand dry conditions and produce reasonable yields even with limited water availability.

Which agricultural practice can help improve soil health and reduce erosion?

  1. No-till farming

  2. Monoculture cropping

  3. Frequent plowing

  4. Burning crop residues


Correct Option: A
Explanation:

No-till farming is a conservation agriculture practice that involves minimal soil disturbance. It helps improve soil structure, increase organic matter content, and reduce soil erosion, making it more resilient to climate change impacts.

How can agroforestry contribute to climate change mitigation?

  1. It reduces the need for synthetic fertilizers

  2. It enhances carbon sequestration in soil

  3. It increases the demand for water resources

  4. It promotes the use of genetically modified crops


Correct Option: B
Explanation:

Agroforestry practices, such as integrating trees and shrubs into agricultural systems, can enhance carbon sequestration in soil. Trees and shrubs absorb carbon dioxide from the atmosphere and store it in their biomass and roots, contributing to climate change mitigation.

Which agricultural practice can help reduce methane emissions from livestock?

  1. Feeding livestock with high-quality feed

  2. Using antibiotics in animal feed

  3. Increasing the number of livestock per unit area

  4. Allowing livestock to graze on natural grasslands


Correct Option: A
Explanation:

Feeding livestock with high-quality feed, such as legumes and grasses, can help reduce methane emissions by improving digestion and reducing the amount of methane produced during the fermentation process in the rumen.

How can farmers reduce the use of synthetic fertilizers in agriculture?

  1. Applying fertilizers based on soil testing

  2. Using organic fertilizers instead of synthetic ones

  3. Increasing the frequency of irrigation

  4. Planting genetically modified crops that require less fertilizer


Correct Option: A
Explanation:

Applying fertilizers based on soil testing helps ensure that crops receive the right amount of nutrients, reducing the risk of over-fertilization and minimizing the need for synthetic fertilizers.

Which agricultural practice can help conserve water resources in agriculture?

  1. Drip irrigation

  2. Flood irrigation

  3. Furrow irrigation

  4. Sprinkler irrigation


Correct Option: A
Explanation:

Drip irrigation is a water-efficient irrigation method that delivers water directly to the roots of plants, minimizing water loss through evaporation and runoff.

How can farmers reduce the vulnerability of their crops to pests and diseases under changing climate conditions?

  1. Using pesticides and herbicides more frequently

  2. Planting genetically modified crops resistant to pests and diseases

  3. Promoting biodiversity in agricultural systems

  4. Increasing the use of synthetic fertilizers


Correct Option: C
Explanation:

Promoting biodiversity in agricultural systems, such as planting diverse crop varieties and maintaining natural habitats, can enhance the resilience of crops to pests and diseases, reducing the need for chemical inputs.

Which agricultural practice can help reduce soil erosion and improve soil health?

  1. Contour farming

  2. Monoculture cropping

  3. Slash-and-burn agriculture

  4. Overgrazing


Correct Option: A
Explanation:

Contour farming is an agricultural practice that involves farming along the contours of the land, helping to reduce soil erosion and improve water infiltration.

How can farmers adapt to changing precipitation patterns due to climate change?

  1. Building dams and reservoirs to store water

  2. Switching to drought-resistant crop varieties

  3. Increasing the use of synthetic fertilizers

  4. Clearing forests to expand agricultural land


Correct Option: B
Explanation:

Switching to drought-resistant crop varieties is an effective adaptation strategy for farmers facing changing precipitation patterns. These varieties can withstand dry conditions and produce reasonable yields even with limited water availability.

Which agricultural practice can help reduce the release of nitrous oxide, a potent greenhouse gas, from agricultural soils?

  1. Using nitrification inhibitors

  2. Applying excessive amounts of nitrogen fertilizers

  3. Burning crop residues

  4. Leaving agricultural fields fallow


Correct Option: A
Explanation:

Using nitrification inhibitors is an effective strategy to reduce nitrous oxide emissions from agricultural soils. These inhibitors slow down the conversion of ammonium to nitrate, thereby reducing the amount of nitrous oxide produced.

How can farmers improve the resilience of their agricultural systems to climate change impacts?

  1. Adopting sustainable agricultural practices

  2. Relying solely on synthetic fertilizers and pesticides

  3. Expanding agricultural land into natural ecosystems

  4. Ignoring the impacts of climate change on agriculture


Correct Option: A
Explanation:

Adopting sustainable agricultural practices, such as crop diversification, soil conservation, and efficient water management, can enhance the resilience of agricultural systems to climate change impacts.
