Declining water tables
Salinization of soils
Land subsidence
All of the above
Answer is Right!
Answer is Wrong!
The correct answer is D. All of the above.
Excessive groundwater extraction for irrigation can lead to a number of problems, including:
- Declining water tables: When groundwater is extracted, the water table drops. This can have a number of negative consequences, including making it more difficult to extract water, reducing the amount of water available for other uses, and causing land subsidence.
- Salinization of soils: When groundwater is extracted, it can leave behind salts that were dissolved in the water. These salts can build up in the soil, making it less productive.
- Land subsidence: When groundwater is extracted, the ground above the aquifer can subside. This can damage infrastructure, such as buildings and roads, and can also make it more difficult to extract water.
It is important to manage groundwater resources carefully to avoid these problems. This can be done by using water conservation measures, such as drip irrigation, and by recycling wastewater.
