Question

Irrigation without proper drainage of water leads to:
A. Desertification
B. Soil erosion
C. Waterlogging
D. All of the above

Answer 1

Hint: Ponds or lakes that get flooded because of improper drainage of water can become a breeding ground for mosquitoes which can cause malaria and other diseases. Irrigation without proper water drainage leads to water logging and salinity of the soil, which can cause severe damage to crops.

Complete step by step answer:
Ponds or lakes that get flooded because of improper water drainage can become a breeding ground for mosquitoes which can cause malaria and other diseases. Maintaining the natural balance between water sources and the earth is important so that soil becomes moist but not soggy. This will make plants' growth easier while protecting them from pests and diseases. To irrigate a field for successful crop production, it is necessary to have proper water drainage from the field. Irrigation without proper water drainage leads to water logging and salinity of the soil, which can cause severe damage to crops.
This causes plants close to the ground to die due to a lack of oxygen in the soil and change in temperature and moisture levels. Excessive use of water for irrigation without proper disposal can negatively affect the environment and a person's physical health. Without getting rid of the excess water, it will likely pollute the soil and lead to erosion.
Option C is the correct answer.

Note:The water table can rise due to excess water added to the fields. This can happen during irrigation or in rainy seasons. In addition, a rising water table is usually caused by groundwater that moves due to earthquakes, volcanoes or geothermal heat from beneath the ground.
