Try these first

1. 1.

   What is over-irrigation?

   Hint

   Think about how much water crops actually need.

2. 2.

   How does seepage affect groundwater levels?

   Hint

   Consider what happens when water escapes from canals.

3. 3.

   What is the major consequence of over-irrigation?

   • Reduced soil fertility
   • Increased crop yield
   • Soil erosion

   Hint

   Think about what happens when crops get too much water.

4. 4.

   True or False: Poor drainage can lead to water accumulation in the soil.

   • True
   • False

   Hint

   Consider what stagnant water indicates.

5. 5.

   Imagine an area with both flat terrain and clayey soil has been over-irrigated for several weeks. Discuss the potential long-term effects of this scenario on agricultural output and local ecosystems.

   Hint

   Consider factors such as soil health, crop yield, and biodiversity.

6. 6.

   Evaluate the implications of urbanization on rural water logging issues, particularly how infrastructure changes can exacerbate the problem.

   Hint

   Think about how cities change natural landscapes.
