GRADE 8 Agriculture – Water harvesting and storage Quiz

1. Which of the following is a common traditional method of water harvesting in Kenya?

Installing sprinkler systems
Using drip irrigation systems
Digging terraces on hills
Building concrete dams
Explanation:

Digging terraces on hills is a common traditional method of water harvesting in Kenya as it helps to prevent soil erosion and retain water for crops.

2. What is the purpose of water harvesting in agriculture?

To conserve water for irrigation
To increase evaporation of water
To reduce soil fertility
To waste water resources
Explanation:

The purpose of water harvesting in agriculture is to conserve water for irrigation, especially during dry seasons, to ensure sustainable crop production.

3. Which of the following is a benefit of water harvesting and storage in agriculture?

Reduced water availability
Improved soil moisture retention
Increased soil erosion
Decreased crop yields
Explanation:

One of the benefits of water harvesting and storage in agriculture is improved soil moisture retention, which helps crops access water during dry periods.

4. What is a common method of storing harvested rainwater on farms in Kenya?

Discarding excess water
Not utilizing collected water
Running sprinklers constantly
Using water tanks or reservoirs
Explanation:

A common method of storing harvested rainwater on farms in Kenya is by using water tanks or reservoirs to ensure water availability during dry periods.

5. Why is proper water harvesting important for sustainable agriculture?

To increase soil erosion
To decrease crop yields
To encourage desertification
To conserve water resources
Explanation:

Proper water harvesting is important for sustainable agriculture because it helps conserve water resources for irrigation and crop production, especially in arid regions like Kenya.

6. Which of the following is a disadvantage of not implementing water harvesting practices in agriculture?

Reduced soil erosion
Increased water availability
Improved crop yields
Limited water supply for crops
Explanation:

A disadvantage of not implementing water harvesting practices in agriculture is limited water supply for crops, leading to decreased yields and food insecurity.

7. What is the primary goal of water harvesting and storage in agriculture?

To waste natural resources
To ensure water availability for crops
To encourage water run-off
To deplete groundwater sources
Explanation:

The primary goal of water harvesting and storage in agriculture is to ensure water availability for crops, especially in regions prone to droughts like Kenya.

8. Which of the following is a sustainable practice for water harvesting in agriculture?

Ignoring water conservation techniques
Implementing rainwater harvesting systems
Avoiding water storage facilities
Using excessive water for irrigation
Explanation:

A sustainable practice for water harvesting in agriculture is implementing rainwater harvesting systems to collect and store water efficiently for crop irrigation.

9. How does water harvesting contribute to environmental conservation in agriculture?

By increasing pollution levels
By reducing water waste
By depleting natural water sources
By promoting deforestation
Explanation:

Water harvesting contributes to environmental conservation in agriculture by reducing water waste and promoting efficient use of limited water resources for sustainable farming practices.

10. What role does water storage play in enhancing food security in Kenya?

It prevents crop failure
It encourages food wastage
It causes soil degradation
It leads to food shortages
Explanation:

Water storage enhances food security in Kenya by preventing crop failure during dry seasons and ensuring continuous food production for the growing population.
