Excessive withdrawal of water for irrigation can lead to:

Depletion of groundwater levels
Waterlogging and salinity
Conflicts over water sharing
All of the above

The correct answer is: All of the above.

Excessive withdrawal of water for irrigation can lead to a number of problems, including:

  • Depletion of groundwater levels. When water is withdrawn from aquifers faster than it can be replenished, the water table can drop. This can lead to a number of problems, including wells going dry, sinkholes forming, and land subsidence.
  • Waterlogging and salinity. When water is applied to land in excess, it can cause the soil to become waterlogged. This can lead to a number of problems, including the growth of salt-tolerant plants, the death of crops, and the contamination of groundwater.
  • Conflicts over water sharing. When water is scarce, it can lead to conflicts between different users, such as farmers, industries, and cities. These conflicts can be difficult to resolve and can have a significant impact on the economy and environment.

It is important to manage water resources carefully to avoid these problems. This includes using water efficiently, recycling water, and protecting water quality.
